In the description of the present disclosure, it should be understood that the terms "upper," "lower," and the like, as defined based on the orientation of the drawing (e.g., fig. 1), are used merely to facilitate description of the present disclosure and to simplify the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, as well as a specific orientation configuration and operation, and thus should not be construed as limiting the present disclosure, and furthermore, the terms "inner and outer" refer to both the interior and exterior of the corresponding structural profile. In addition, the terms "first," "second," etc. are merely intended to distinguish one element from another element, and are not sequential or important.

In the description of the present disclosure, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "connected," and "mounted" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art as the case may be.

In the related art, the bag-type dust collector applied to the desulfurization and dust removal system can receive the flue gas from the desulfurization reaction tower through the flue and separate the received desulfurization flue gas in the bag-type dust collector main body, so that the desulfurization ash in the flue gas drops downwards into the ash bucket of the bag-type dust collector and is discharged to a designated position through the discharge port of the ash bucket, but the desulfurization flue gas can produce fallen iron sheets after wearing the flue and drops into the ash bucket, so that the discharge port of the ash bucket is blocked, the material level in the ash bucket is continuously raised, and then the material weight in the ash bucket exceeds the bearing limit of the ash bucket, so that the risk of collapse of the ash bucket exists.

In view of this, the present embodiment provides an ash bucket of a bag house, which is capable of preventing the level of the material in the ash bucket from continuously rising after the discharge port is blocked, and thereby avoiding the risk of the ash bucket collapsing.

Next, the specific structure of the hopper will be described in detail with reference to fig. 1 and 2.

As shown in fig. 1 and 2, the ash bucket of the bag-type dust collector comprises an ash bucket body 100 and a bypass pipe 200, wherein a material cavity 110 is formed in the ash bucket body, a material guiding opening 120 is formed in the top of the ash bucket body 100, the material guiding opening 120 is communicated with the material cavity 110 and is used for being communicated with the interior of a dust collector main body 600 of the bag-type dust collector, and a discharge opening 130 communicated with the material cavity 110 is formed in the bottom of the ash bucket body 100; the bypass pipe 200 has a first end fixed to the hopper body 100 and communicating with the chamber 110, and a second end lower than the first end, the first end communicating with the chamber 110 at a position higher than the discharge port 130 and lower than the guide port 120.

When the ash bucket is applied to the bag-type dust collector, the top material guiding opening 120 of the ash bucket is communicated with the interior of the dust collector main body 600 of the bag-type dust collector, after the material sheet falling from the flue 300 is accumulated at the bottom of the material cavity 110 of the ash bucket to cause the blockage of the material outlet 130 of the ash bucket, the material level in the material cavity 110 of the ash bucket is raised due to the fact that the ash bucket continuously receives the desulfurized ash from the bag-type dust collector main body 600, and the first end of the bypass pipe 200 is higher than the material outlet 130 and lower than the material inlet of the ash bucket, so that after the material level rises and reaches the position where the first end of the bypass pipe 200 is communicated with the material cavity 110, the desulfurized ash received by the ash bucket subsequently automatically enters the bypass pipe 200 from the first end, so that the bypass pipe 200 can discharge the continuously increased desulfurized ash in the ash bucket, and the material level in the ash bucket is prevented from being further raised, and the material weight in the material cavity 110 of the ash bucket is kept within the load weight of the ash bucket, and the risk of falling off the ash bucket due to the loaded material is avoided. In addition, the bypass pipe can enable the ash bucket to be smoothly discharged, and the reduction of desulfurization ash circulating to the absorption tower caused by unsmooth ash bucket discharging is avoided, so that the desulfurization efficiency can be ensured.

Since the bag-type dust collector is generally used in a desulfurization and dust removal system, if the blocked ash bucket discharge port 130 is to be dredged, the whole desulfurization and dust removal system unit needs to be stopped, which brings a great amount of economic loss to enterprises. And be provided with bypass pipe 200 in the ash bucket that this disclosure provided, bypass pipe 200 can discharge the desulfurization ash in the ash bucket body 100 after ash bucket discharge port 130 blocks up, avoids the ash bucket to have the risk of collapsing because of the material level continuously risees, need not to shut down the unit of the desulfurization dust pelletizing system that whole sack cleaner is located and carry out the dredging operation of ash bucket, also can realize the emission of the desulfurization ash in the ash bucket to this has reduced the economic loss that brings the unit shut down. As for the dredging operation of the discharge opening 130 of the ash bucket, the whole desulfurization and dust removal system can be delayed until the periodic shutdown check and maintenance are performed, so that the shutdown operation performed for dredging the discharge opening 130 of the ash bucket alone is avoided.

It should be noted that, the bypass pipe 200 has a pipe structure, the first end and the second end are two ends of the bypass pipe 200, the first end of the bypass pipe 200 is fixed on the ash bucket body 100, and the channel inside the bypass pipe 200 is communicated with the material cavity 110. The second end of the bypass pipe being lower than the first end means that after the first end of the bypass pipe 200 is communicated with the ash bucket body 100, the second end of the bypass pipe 200 is located at a lower level than the first end of the bypass pipe 200, so that the materials such as the desulfurization ash entering from the first end of the bypass pipe 200 can move to the second end under the action of gravity.

The first end of the bypass tube 200 is in communication with the cavity 110 at a position higher than the discharge port 130 so that the discharge port 130 does not block the bypass tube 200 when it is slightly blocked. Meanwhile, the first end of the bypass pipe 200 is communicated with the material cavity 110 at a position lower than the material guiding opening 120, so that the desulfurized ash can be collected by the ash bucket material cavity 110 after entering the ash bucket through the material guiding opening 120, and then enters the bypass pipe 200 or the discharge opening 130.

In addition, it should be noted that, in the actual use process, the ash bucket provided in this embodiment can also solve the problem that the discharge opening 130 of the ash bucket is blocked due to other reasons, for example, the desulfurized ash plate is blocked and the discharge opening 130 is blocked due to the moisture in the ash bucket. In addition, the level of the ash bucket can be detected by a level detection device in the ash bucket, and the level detection device is a common device in the field, so that detailed description thereof is omitted in this embodiment.

The communication position of the bypass pipe 200 with the hopper's hopper 110 refers to the communication position of the first end of the bypass pipe 200 with the hopper's hopper 110. The end of the first end of the bypass tube 200 may be flush with the wall of the chamber 110 forming the hopper or may protrude from the wall. The first end of the bypass pipe 200 protrudes out of the wall of the material cavity, which means that the end of the first end of the bypass pipe 200 is placed in the material cavity 110 of the ash bucket and spaced apart from the wall of the material cavity of the ash bucket by a certain distance, and the side wall of the bypass pipe 200 is fixed with the ash bucket. The second end of the bypass pipe 200 may be connected to other equipment connected to the material inlet 120, or may be connected to a dedicated desulfurization ash collecting device, so that a user may select the second end according to actual needs.

In some embodiments, the inner diameter of the bypass tube 200 is greater than or equal to the caliber of the discharge port 130, so that the bypass tube 200 can have a sufficiently large passage for the desulfurization ash to flow, and the problem that the level of the ash bucket in the ash bucket still slowly rises due to untimely discharge of the desulfurization ash by the bypass tube 200 is avoided.

Optionally, the ash bucket body 100 is tapered, the interior of the ash bucket body 100 has a tapered material cavity 110, and the cross-sectional area of the material cavity 110 in the ash bucket body 100 is gradually reduced from the top of the ash bucket body 100 to the bottom of the ash bucket body 100. The desulfurized fly ash separated from the bag-type dust collector body 600 falls into the material guiding port 120, enters the material cavity 110 through the material guiding port 120, is collected and collected by the tapered material cavity 110, and is discharged from the discharge port 130 to a designated position. In some alternative embodiments, the ash bucket body 100 may also be straight cylindrical.

In some embodiments, the distance from the location of the first end of the bypass tube 200 in communication with the cavity 110 to the discharge port 130 is less than the distance from the location of the first end of the bypass tube 200 in communication with the cavity 110 to the pilot port 120, such that the location of the first end of the bypass tube 200 in communication with the cavity 110 is closer to the discharge port 130, while remaining higher than the discharge port 130. Because the material cavity 110 in the ash bucket is conical and has a collecting effect on the desulfurized ash, the communication position between the first end of the bypass pipe 200 and the material cavity 110 is closer to the discharge port 130, so that the flow of the desulfurized ash entering the bypass pipe 200 is larger, and the continuous increase of the material level of the materials in the ash bucket is further prevented.

Optionally, the side wall of the ash bucket body 100 is provided with a first connection port 150, and the first end of the bypass pipe 200 is communicated with the first connection port 150, that is, the connection position of the first end of the bypass pipe 200 and the material cavity 110 is located on the side wall of the ash bucket. After the first connecting port 150 is arranged on the side wall, the iron sheet falling from the flue 300 can slide off the side wall and cannot directly stay on the side wall, so that the situation that the iron sheet just falls on the first connecting port 150 to block the first connecting port 150 is avoided.

Further, as shown in fig. 1, a first reinforcing plate 140 is fixed on a side wall of the ash bucket body 100, the first reinforcing plate 140 is located at a position on the ash bucket body 100 where a first connection port 150 is formed, and the first connection port 150 penetrates through the first reinforcing plate 140. After the first reinforcing plate 140 is arranged, the rigidity intensity of the ash bucket body 100 at the position where the first reinforcing plate 140 is arranged can be enhanced to compensate the problem that the side wall intensity of the ash bucket body 100 is reduced due to the fact that the first connecting port 150 is arranged on the side wall of the ash bucket body 100, and further the cracking damage of the ash bucket body 100 caused by the reduction of the intensity of the ash bucket body 100 is avoided.

The first end of the bypass pipe 200 is fixed with a first flange 220, and the first flange 220 is detachably connected to the first reinforcing plate 140, so that the bypass pipe 200 can be detached and replaced after being worn. Meanwhile, since the first flange 220 needs to be connected with bolts, and the first flange 220 is connected with the first reinforcing plate 140, the matched bolt holes are also formed in the first reinforcing plate 140, so that further reduction of the strength of the ash bucket caused by the fact that the bolt holes are formed in the ash bucket can be avoided.

It should be noted that, in this embodiment, the first reinforcing plate 140 is disposed on the outer sidewall of the ash bucket to better connect the first flange 220, and meanwhile, it is also capable of avoiding that the first reinforcing plate 140 is disposed on the inner sidewall of the ash bucket to cause the first reinforcing plate 140 to protrude from the inner sidewall of the ash bucket, so as to easily block the desulfurized ash from sliding down. Naturally, after chamfering the edge of the first reinforcing plate 140, the first reinforcing plate 140 may be disposed on the inner side wall of the hopper, but the space of the material chamber 110 in the hopper may be reduced to some extent.

In addition, in the present embodiment, the fixing manner of the first reinforcing plate 140 and the ash bucket is welding and fixing, so as to ensure the tightness and stability of the connection between the first reinforcing plate 140 and the ash bucket. Of course, in some alternative embodiments, the fixing manner of the first reinforcing plate 140 and the ash bucket may be implemented by a combination manner of glue applying and sealing after fastening, or other fixing manners capable of implementing connection stability and tightness between the first reinforcing plate 140 and the ash bucket.

In some alternative embodiments, the bypass pipe 200 is provided with a valve 210, and the bypass pipe 200 can be selectively turned on or off by controlling the opening and closing of the valve 210. In this way, when the discharge opening 130 of the ash bucket is in an unblocked state, the valve 210 can be controlled to cut off the bypass pipe 200 so that the desulfurization ash in the ash bucket is discharged from the discharge opening 130, and after the discharge opening 130 is blocked, the valve 210 can be controlled to open the bypass pipe 200 so that the desulfurization ash is discharged from the bypass pipe 200. Of course, in actual use, when the exhaust port 130 is in the unblocked state, the control valve 210 may conduct the bypass pipe 200, so that part of the desulfurization ash falling into the bypass pipe 200 may be discharged from the bypass pipe 200.

In some embodiments, the bypass tube 200 is a straight tube such that the channels within the bypass tube 200 are straight channels, thereby reducing the chance of the desulfurized ash accumulating within the bypass tube 200.

Further, on the basis that the bypass pipe 200 is a straight pipe, the bypass pipe 200 can be a circular pipe, so that the channel inside the bypass pipe 200 is a circular channel, dead angles of the channel inside the bypass pipe 200 are reduced, and the probability of the desulfurized ash being accumulated in the bypass pipe 200 is further reduced.

Based on the ash bucket of the bag-type dust collector, the disclosed embodiment also provides a bag-type dust collector, the structure of which is shown in fig. 2, the bag-type dust collector comprises a dust collector main body 600 and the ash bucket provided in the above embodiment, the ash bucket is fixed below the dust collector main body 600, and the material guide opening 120 of the ash bucket is communicated with the interior of the dust collector main body 600 so as to receive the desulfurization ash separated from the dust collector main body through the material cavity 110 of the ash bucket.

After the discharge port 130 of the hopper is blocked, the desulfurized ash is accumulated in the material cavity 110 of the hopper to raise the material level in the hopper, and when the material level rises to the height where the first end of the bypass pipe 200 is communicated with the hopper body 100, the desulfurized ash can be discharged from the bypass pipe 200, so that the further rise of the material level is avoided.

The present disclosure also provides a desulfurization dust removal system, a part of which is shown in fig. 3, in which a desulfurization reaction tower 500 and the bag-type dust collector provided in the above embodiment are included, a discharge port of the desulfurization reaction tower 500 is communicated with a feed port of a dust collector main body 600 through a flue 300, a discharge port 130 of an ash bucket is communicated with the desulfurization reaction tower 500 through a circulation pipe 400, and a second end of a bypass pipe 200 of the ash bucket is communicated with the circulation pipe 400.

After the sulfur-containing flue gas entering from the inlet of the desulfurization reaction tower 500 is subjected to desulfurization treatment in the desulfurization reaction tower 500, the flue gas enters the flue 300 from the discharge port of the desulfurization reaction tower 500, and is separated in the dust remover main body 600 flowing to the bag-type dust remover along the flue 300, the desulfurized ash separated from the flue gas falls into the ash bucket below the dust remover main body 600, and the clean flue gas separated from the flue gas is discharged from the exhaust port (not shown in the figure) of the dust remover main body 600. After the discharge port 130 of the ash bucket is blocked, the accumulated desulfurization ash in the ash bucket can be discharged from the bypass pipe 200 and enter the circulating pipe 400, and then the circulating pipe 400 is used for conveying the desulfurization ash to the desulfurization reaction tower 500 again to be used as the desulfurization ash required for constructing the bed of the desulfurization reaction tower 500, so that the recycling of the desulfurization ash is realized, and the influence on the desulfurization efficiency due to unsmooth unloading of the ash bucket is avoided.

It should be noted that, in the present embodiment, the circulation pipe 400 is a pipe connected between the discharge port 130 of the ash bucket and the desulfurization reaction tower 500 in the desulfurization and dust removal system. The arrangement uses the existing circulation pipe 400 without separately providing a pipe to be connected to the second end of the bypass pipe 200, thereby saving costs. Of course, in some alternative embodiments, the second end of the bypass pipe 200 and the desulfurization tower 500 may be connected by providing a separate pipe without consideration of costs and complexity of piping arrangement.

In some embodiments, as shown in fig. 4, the second end of the bypass pipe 200 is provided with a second flange 230, a second reinforcing plate 440 is provided outside the circulation pipe 400, a second connection port provided on the circulation pipe 400 penetrates the second reinforcing plate 440, the second flange 230 is detachably connected with the second reinforcing plate 440, so that the second end of the bypass pipe 200 is detachably connected with the circulation pipe 400, and the bypass pipe 200 is communicated with the circulation pipe 400 through the second connection port. Of course, in some alternative embodiments, the second end of the bypass tube 200 may be connected to the circulation tube 400 by welding or other connection means.

In some embodiments, as shown in fig. 3, the bypass tube 200 has an included angle α at the junction with the circulation tube 400, the included angle α ranging from: alpha is more than or equal to 30 degrees and less than or equal to 90 degrees. In this angular range, the bypass pipe 200 is in an inclined state, and the desulfurization ash in the bypass pipe 200 can more smoothly fall into the circulation pipe 400.

Alternatively, the angle α=60° at the junction of the bypass tube 200 and the circulation tube 400.

It should be noted that, in the circulation pipe 400 connected to the discharge port 130 of the ash bucket, the circulation pipe 400 is divided into the material channel 410 and the air blowing channel 420 by the vulcanized canvas 430, the discharge port 130 and the second end of the bypass pipe 200 are both communicated with the material channel 410, and the air in the air blowing channel 420 can pass through the vulcanized canvas 430 and act on the desulfurized ash in the material channel 410, so that the blockage of the material channel 410 of the circulation pipe 400 caused by the long-time adhesion of the desulfurized ash to the wall of the material channel 410 is avoided. And when the included angle of the connection of the bypass pipe 200 and the circulation pipe 400 is 30 to 90 degrees, it is possible to prevent the desulfurization ash from directly washing the vulcanized canvas 430 to easily damage the vulcanized canvas 430.

The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the embodiments described above, and various simple modifications may be made to the technical solutions of the present disclosure within the scope of the technical concept of the present disclosure, and all the simple modifications belong to the protection scope of the present disclosure.
