Description

Technical Field

[0001] The invention relates to the field of waste gas purification and exhaust systems, and in particular to a ground well purification and exhaust settling type ground well deodorizer. Background Art

[0002] In some chemical, pharmaceutical, printing and dyeing industries, waste gas often overflows from the manhole covers of sewage pools or sewage ditches. Waste gas also often overflows from the manhole covers of municipal sewage drainage ditches, causing environmental pollution, especially the overflow of odorous or toxic and harmful gases, which seriously affects the physical and mental health of people nearby.

[0003] At present, the way to prevent the overflow of underground well waste gas is often to seal the well cover. However, since some of the underground well waste gas is the result of long-term fermentation of microorganisms, and some is volatilized from sewage, the generation of these gases often generates pressure and heat, causing the pressure of the sewage ditch or sewage pool to be greater than the environmental pressure, and the sealing solution fails to a certain extent. At the same time, some well covers need to be drained and cannot be completely sealed for a while, causing the overflow of odor or toxic and harmful gases, affecting the environment.

[0004] Therefore, it is necessary to design a ground well deodorizer which neither hinders drainage nor has waste gas overflow. Summary of the invention

[0044] The purification module includes an air membrane assembly. A filter air membrane 29 is installed below the air membrane cylinder 28. The filter air membrane 29 can be designed as a multi-layer air membrane 29 or a single layer. Each layer of the air membrane 29 is made of a specific material to prevent specific exhaust gas from leaking outward and catalytically decompose on its surface.

[0047] A water inlet is provided at the bottom of the float locator 12, and the bottom of the float locator 12 is in the shape of a hollow column. An arc-shaped protrusion is provided at the center of the top of the float locator 12, and a hollow column is provided at the center of the top of the arc-shaped protrusion. The hollow column is connected to the top of the float locator 12, and the maximum diameter of the hollow column is smaller than the minimum diameter of the bottom of the float locator 12.

[0048] The float 13 is arranged in the float locator 12. The bottom of the float 13 is a column, which has the same shape as the bottom of the float locator 12. The maximum diameter of the column is smaller than the inner diameter of the hollow column of the float locator 12. A protrusion matching the water inlet is provided at the bottom of the float 13, and a push rod is provided at the top of the column. A sealing block is provided at the top of the push rod. The maximum diameter of the sealing block is smaller than the inner diameter of the hollow column of the float locator 12, and the maximum diameter of the exhaust pipe 20 is smaller than the diameter of the sealing block.

[0049] like Figure 4 As shown, when installing the present invention, first use a bolt kit to penetrate the installation hole to fix the drainage cylinder to the appropriate sunken position of the ground manhole seat without interfering with the ground manhole cover, then insert the air film cylinder 28 of the purification module into the positioning groove 11 on the base 10, insert the exhaust pipe 20 into the float positioner 12 near the top of the float 13 in the float positioner 12, and cover the ground manhole cover to complete the installation of the present invention.

[0050] The base 10 is arranged in the drainage cylinder 1. The bottom of the drainage cylinder 1 is provided with multiple through holes. The base is a hollow cylinder. The base 10 is connected to the outside through the through holes. A positioning groove 11 is provided on the base. The maximum diameter of the positioning groove 11 is the same as the outer diameter of the air film cylinder 28, and the minimum diameter of the positioning groove 11 is the same as the inner diameter of the air film cylinder 28. The bottom of the air film cylinder 28 is inserted into the positioning groove 11. The physical filter 27 in the air film cylinder 28 is arranged above the air film 29 to intercept the dust weathered and fallen by the filter material 25 above, and effectively reduce the dust and other impurities falling on the surface of the air film 29. The outer diameter of the bottom of the filter cylinder 24 is the same as the inner diameter of the top of the air film cylinder 28. The bottom of the filter cylinder 24 is connected to the top of the air film cylinder 28 by bolts. The filter cylinder 24 is filled with activated carbon and ceramics. , molecular sieve, etc., which have microporous adsorption function and are impregnated with filter materials 25 of specific materials. A conical outlet cover 23 is set on the top of the filter cartridge 24. The outlet cover 23 is connected to the filter cartridge 24 by bolts. An opening is set on the top of the outlet cover 23, and a mesh filter plate 22 is set on the top of the outlet cover 23. The maximum diameter of the mesh filter plate 22 is the same as the inner diameter of the drainage cartridge 1, which is used to intercept dirt and impurities. One end of the tee pipe 21 is connected to the outlet of the outlet cover 23, and the other two ends of the tee pipe 21 are respectively connected to the exhaust pipe 20. The other ends of the two exhaust pipes 20 extend downward from the outlet 16 of the float positioner 12 to above the float 13 in the float positioner 12. The float positioners 12 are symmetrically distributed at the opposite ends of the base 10.

[0051] like Figure 5 As shown, when rainwater flows into the well, it first enters through the vent hole of the well cover and flows into the mesh filter plate 22, through which garbage such as leaves are filtered, and then the rainwater continues to flow through the mesh filter plate 22 to the base 10 of the drainage module. When the rainwater gathers to a certain level, the collected rainwater enters the float positioner 12 through the water inlet 17 of the float positioner 12, floats the float 13 through the buoyancy, opens the water leakage port on the base 10, and the rainwater flows down from the water leakage port of the base 10 to the sewage ditch under the well, completing a drainage process. When the float 13 opens the water leakage port of the base 10, the blocking block on the top of the float 13 floats up to the hollow column and abuts against the outlet of the exhaust pipe, thereby closing the outlet 16 of the exhaust pipe 20, playing a sealing role, and ensuring that the water does not flow back into the filter cartridge 24 when the water level is high.

[0052] like Figure 6As shown, when no water flows into the ground well, the ground well enters the ventilation exhaust mode. Since the pressure of the waste gas in the sewage pool or sewage ditch is greater than the atmospheric pressure, the waste gas passes through the exhaust hole 15 of the base 10 and enters the purification module, and first contacts the air membrane 29. Most of the waste gas is isolated by the air membrane 29 and gathers on the surface of the air membrane 29 to form large molecular clusters. Part of it condenses into liquid and drips back into the sewage ditch, and part of it directly reacts with the catalyst material on the surface of the air membrane 29 to decompose into non-toxic and harmless gas and passes through the air membrane 29. The gas passing through the air membrane 29 then passes through the physical filter 27 (the function of the thin plate-type physical filter 27 is to prevent the dust from weathering and falling from the filter material 25 above from falling on the surface of the air membrane 29). The gas passing through the physical filter 27 then passes through the filter mesh bottom plate of the filter component and enters the filter material 25 in the filter component cylinder. Part of the outflowing exhaust gas is adsorbed and decomposed again into non-toxic and harmless gas, which is collected to the outlet cover 23 through the filter material 25, and then enters the three-way pipe 21 from the outlet cover 23. The three-way pipe 21 is divided into two paths to each exhaust pipe 20, and enters the float positioner 12 from the exhaust pipe 20. Since there is no water in the float positioner 12 at this time, the float 13 drops and does not rise. The exhaust pipe 20 is opened, and comes out from the air outlet 16 of the float positioner 12, enters the outside of the purification module and the inside of the drainage module, and then passes through the mesh filter plate 22, and is discharged through the vent of the manhole cover, completing a waste gas deodorization and discharge process, and the cycle is repeated.
