According to dewatering installation of the present invention, can avoid electric submersible pump is placed in the gas guide well, thereby prevent to produce the electric spark danger of blasting.In addition, this self-draining arrangement can be manually on duty, thereby saved manpower.
Description of drawings
Fig. 1 is the schematic diagram that illustrates according to an exemplary embodiments of the present invention.
Fig. 2 shows the typical case of the floating ball device that is used for water level controller of the present invention.
The specific embodiment
Below with a specific embodiment exemplary illustration according to self-draining arrangement of the present invention.
As shown in Figure 1, header 10 is one and has 11 the cylinder of going to the bottom, and has water inlet 12 at the lower sides of cylinder.In the inboard of water inlet a catch is arranged, this catch is hinged on the inwall (not shown) of cylinder.The outer water of header can be pushed this catch open and enter in the header 10.But when the pressure of header was outer greater than pipe, catch was then sealed water inlet 12, was back to outside the pipe to avoid managing interior water.
Upper position at header also has baffle plate 14, and header and outside sealing are provided.Baffle plate is provided with through hole 16, is used to insert wireway 15.Wireway 15 links to each other with compressed air hose 20, is used for input compressed air in pipe, and it opens and closes compressed air hose 20 by 22 controls of first control electromagnetic valve.Wireway 15 also links to each other with air hose 30, and it opens and closes air hose 30 by 32 controls of second control electromagnetic valve.
In actual applications, header is positioned in the gas guide well.The operating principle of this dewatering installation is, the water level that is gone up when float 52 holds up, and when being positioned at a predetermined primary importance, controlling organization 54 starts first control electromagnetic valve 22, closes second control electromagnetic valve 32, with injecting compressed air in header 10.At this moment water inlet 12 is closed in the influence that is stressed, catch, and water orders about down at pressure and discharged by gutter 40 in the header.When float 52 was positioned at a second place that is lower than primary importance, controlling organization 54 cut out first control electromagnetic valve 22, opens second control electromagnetic valve 32, and air hose is communicated with below 14 with the baffle plate of header, and header can be via water inlet 12 water inlets.So move in circles, realize automatic draining.
Fig. 2 illustrates the floating ball device of the water level controller in the present embodiment.It is a floating-ball level switch 52, this switch is the snap switch 55 that one or more are set in airtight metal or plastic pipe 60, then pipe 60 is run through one or more hollows and the inner ball float 52 that ring magnet 56 is housed, and utilize first retainer ring 62 be located at pipe 60 primary importances and at second retainer ring, the 64 control ball floats of the second place and snap switch on relevant position, ball float is fluctuated within the specific limits.Utilize the magnet of ball float to remove to attract the contact of magnetic reed switch, the control of liquid level is done in the action that produces Push And Release.
Particularly, snap switch is fixed near the primary importance, has first shell fragment 551 and second shell fragment 552.Under normal conditions, first shell fragment 551 and second shell fragment 552 are in not contact condition.When ball float 52 moved to primary importance, magnet 56 made these two shell fragments contact, thus the conducting connecting circuit.At this moment first electromagnetic valve 22 is activated, and to realize being communicated with of compressed air hose 20 and wireway 15, enters compressed air in header.When ball float 52 moved to the second place, these two shell fragments 551 and 552 disconnected, thereby disconnected connecting circuit.At this moment first electromagnetic valve 22 is closed, and second electromagnetic valve 22 is opened, and the gas in the header can be discharged from air hose 30.
It should be understood that can be used for level controling mechanism of the present invention is not limited to aforesaid way.Should there be a lot of liquid (water) level controller can realize function required among the present invention in the prior art.For example, this level controling mechanism can also be realized the opening and closing of compressed air hose and air hose by mechanical connection.For a specific example, float 52 can be fixedly connected on a fly rod, this fly rod passes baffle plate 14 and can fluctuate, precalculated position above fly rod is in baffle plate 14 is provided with a plurality of projections, these projections can be stirred first switch and second switch corresponding to the above-mentioned primary importance and the second place, and this first switch and second switch can be controlled the opening and closing of compressed air hose and air hose.In this case, only need to realize that the hermetic seal between baffle plate and the fly rod gets final product, this is to be easy in the prior art realize.
Can there be other modes to realize the function that liquid level is controlled, for example respond to the position of float, and signal is conveyed to executing agency, further control the opening and closing of first switch and second switch by executing agency by magnetic induction or infrared induction mode.This is to realize easily in the prior art equally.
One of them advantage of the present invention is, can discharge the interior ponding of gas guide well of refuse landfill automatically, makes the guide well just can realize degassing function safely, continuously without manually-operated.Second advantage of the present invention be, owing to discharge water in the well by compressed-air actuated exerting pressure, need not to lay submersible pump in the shaft bottom, not only prolongs the life-span of device therefor, but also be easy to the maintenance of equipment.The 3rd advantage of the present invention be, by this device is installed, landfill gas guide well remained than low water stage, improves the air guide effect of air guide well greatly, improves the gas collection efficiency of whole landfill yard.The present invention can bring following environmental benefit for refuse landfill: first stink control effect improves; It two is the dischargings that reduce greenhouse gases and toxic gas.The present invention also has the utilization rate that improves landfill gas, reduces the landfill cost, reduces the benefits such as potential safety hazard that the landfill gas migration causes.
Self-draining arrangement according to the present invention is not limited to the gas guide well of refuse landfill, and it can be used for the self-draining water cellar of other needs, well in the same old way.
Abovely embodiments of the present invention are described, but these embodiments only are for exemplary purposes rather than restriction the present invention in conjunction with an exemplary embodiments.It should be understood that those skilled in the art can be under the prerequisite that does not deviate from scope and spirit of the present invention, change and revise for the specific embodiment.Similarly, except above-mentioned embodiment, can also find many specific embodiment in the appended claims.
