Abstract
The utility model relates to an off-gas treating device, in particular to an apparatus for intercepting dust in off-gas in a dry de-dusting device. The apparatus for intercepting dust in off-gas is arranged between a main pipe outlet of a main dust intercepting device body and an outlet pipe of the dust collection device and is communicated with the main dust intercepting device body and the dust collection device, and the apparatus for intercepting dust in off-gas comprises a pair of flanges for clamping a high-temperature resistance filter screens. With the adoption of the apparatus, the dust in the off-gas is intercepted and cleaned automatically, and thus the normal production is ensured.
Description
Technical field
The utility model relates to exhaust gas processing device, relates in particular to the exhaust gas processing device of dry-method dust-removal device.
Background technology
During industrial and commercial bank already produces; The tail gas recycle project often adopts dry-method dust-removal device, be used for the dedusting of industrial tail gas, and existing dry method dust is in service; Clogging phenomenon often takes place in the gravitational dust collection before the thick gas blower fan and cyclone dust removal body and the associated conduit; Cause thick gas blower fan to move in the time of serious, perhaps certain section is moved for negative pressure in the system, causes that oxygen content exceeds standard in the system.The frequency of keeping in repair in the production significantly increases, and directly the output generation to production unit has a strong impact on.The deashing measure that present each production unit is taked is hammering tank body and pipeline, lets dust receive vibration to freely fall to tank base.Its shortcoming is:
1. in producing, long-term hammering must cause malformation, destroys.
2. long-term hammering deashing, what the operating personnel faced is on-the-spot high temperature, dust and coal gas, operating environment is abominable, and the lost labor.
3. a large amount of dusts finally overstocks at thick gas fans entrance place, stops up air-flow, causes blower fan normally to move, and finally can't produce.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and provides a kind of tail gas of dry-method dust-removal device to cut the dirt device.Dust in the utility model amputation tail gas, and can clean automatically, ordinary production ensured.
For addressing the above problem, a kind of tail gas of dry-method dust-removal device cuts the dirt device, and it is arranged between the trunk line outlet that cuts the dirt device body and the dust arrester outlet conduit and with both and is communicated with, and it comprises the flange of a pair of this high temperature resistant filter screen of clamping.
The tail gas of described dry-method dust-removal device cuts the dirt device, and said tail gas cuts the dirt device and also comprises a pressure transmitter and the nitrogen sparge tube that is positioned at the trunk line outlet, and this nitrogen sparge tube is provided with a magnetic valve, and said pressure transmitter is connected to this magnetic valve.
High temperature resistant type filter screen between two flanges of the utility model can be tackled the dust that floats in each dedusting tank body effectively, is unlikely to cause a large amount of dust stratifications in pipeline and the blower fan.When pressure transmitter detects pressure and changes, reach certain setting value after, magnetic valve is opened automatically, pours nitrogen filter screen is purged, and has exempted the conventional artificial hammering method and has beaten the grey mode of unloading.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model sketch map.
The specific embodiment
As shown in Figure 1, trunk line 1 among the figure, and its caliber is identical with tank body outlet conduit diameter.A kind of industrial tail gas cuts the dirt device, and its feature is that the filter screen of bottom can tackle dust effectively in the dedusting tank body, and it comprises:
Two flanges 2, it is positioned at cuts a dirt device bottom, one with the end opening welding that cuts dirt device trunk line, weld the upper end of another and dedusting tank body outlet conduit.
The filtering net plate 3 of a high temperature resistant type is installed between two flanges, uses bolted flange, and the filtering net plate of high temperature resistant type is clamped by flange; Filter screen can be tackled the dust that floats in each dedusting tank body effectively, and this filter screen can be changed easily.
A small-bore pipeline inserts from the left side and cuts in the dirt device trunk line, and the porch installs a magnetic valve 4 additional, and the exit is downwards crooked, installs a diverging duct 5 additional, and pipeline internal medium is a nitrogen;
Be positioned at and cut dirt apparatus main body pipeline right side a pressure transmitter 6 is installed,, set certain force value and be 4 breakdown action, set the appropriate action time as open and close cycle of 4, the interior nitrogen amount of pouring of control main pipeline with 6 and 4 interlocked control.
When the high temperature resistant type filter screen was progressively stopped up by dust, the pressure in the filter screen upper pipe must descend, and the pressure transmitter that is in the right side will detect the variation of this pressure, reach certain setting value after, magnetic valve is opened automatically, pours nitrogen filter screen is purged.
Claims (2)
1. the tail gas of a dry-method dust-removal device cuts the dirt device, and it is arranged between the trunk line outlet that cuts the dirt device body and the dust arrester outlet conduit and with both and is communicated with, and it is characterized in that it comprises the flange of a pair of this high temperature resistant filter screen of clamping.
2. the tail gas of dry-method dust-removal device according to claim 1 cuts the dirt device; It is characterized in that; Said tail gas cuts the dirt device and also comprises a pressure transmitter and the nitrogen sparge tube that is positioned at the trunk line outlet; This nitrogen sparge tube is provided with a magnetic valve, and said pressure transmitter is connected to this magnetic valve.
