Description

Technical Field

[0001] The invention relates to a high-temperature sewage odor treatment technology, and more specifically, to a breathable manhole cover for high-temperature sewage treatment. Background Art

[0002] Since high-temperature sewage will continuously emit a large amount of odor during the transportation process, and since the sewage pipes are closed, a large amount of odor will be released from the sewage manhole covers, affecting the environment.

[0003] The existing high-temperature sewage produces a large amount of high-temperature odor during transportation, which is blocked by sealing. However, due to the large amount of odor generated by high-temperature sewage, blocking will cause a large amount of odor to accumulate in the sewage pipe, increase the pressure in the pipe, and eventually penetrate the sewage pool and leak to the ground. Summary of the invention

[0004] In view of the defects existing in the prior art, the purpose of the present invention is to provide a breathable manhole cover for high-temperature sewage treatment, which solves the problem of manhole covers emitting odor during high-temperature sewage transportation, resulting in a poor on-site environment.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] A breathable manhole cover for high-temperature sewage treatment, comprising a spray treatment component and a filter component arranged on the spray treatment component;

[0007] The spray treatment component includes a water collection tank, a well cover, a bottom plate assembly and a spray assembly;

[0008] The manhole cover covers the top of the water collection tank, and the bottom plate assembly overlaps the bottom of the water collection tank;

[0009] The spray assembly is arranged inside the water collection tank;

[0010] The filter component includes a plurality of filter cartridges, and the bottom of each filter cartridge is arranged on the manhole cover and communicated with the interior of the water collection tank.

[0011] Preferably, the edge of the manhole cover is movably connected to the water collecting trough through a screw rod and a nut.

[0012] Preferably, the bottom plate assembly includes a bottom plate body overlapped on the bottom of the sump, and a plurality of drainage pipes arranged on the bottom plate body.

[0013] Preferably, the spray assembly includes a mounting box, a spray head and a pipeline;

[0014] The installation box is arranged on the outer side of the water collecting tank;

[0015] The nozzle is arranged inside the water collection tank;

[0016] One end of the pipeline is communicated with an external water source, and the other end passes through the installation box and the bottom plate body in sequence and is communicated with the nozzle.

[0017] Preferably, a diaphragm valve is provided on the pipeline in the installation box.

[0018] Preferably, the filter cartridge includes a rain cap, a third-stage filter cartridge, a second-stage filter cartridge and a first-stage filter cartridge connected in sequence from top to bottom;

[0019] A plurality of ventilation holes are evenly distributed on the manhole cover, and the bottom of the primary filter cartridge is arranged in the ventilation holes.

[0035] The spray assembly 14 is disposed inside the water collection tank 11 .

[0036] The filter component 2 includes a plurality of filter cartridges 21 . The bottom of each filter cartridge 21 is disposed on the manhole cover 12 and communicates with the interior of the water collection tank 11 .

[0037] The bottom plate assembly 13 includes a bottom plate body 131 overlapped at the bottom of the sump 11 , and a plurality of drainage pipes 132 disposed on the bottom plate body 131 .

[0038] The spray assembly 14 includes a mounting box 141 , a spray head 142 and a pipeline 143 .

[0039] The installation box 141 is disposed on the outer side of the water collecting tank 11 .

[0040] The nozzle 142 is disposed inside the water collection tank 11, close to the center.

[0041] One end of the pipe 143 is connected to an external water source, and the other end is turned through the quick-release connector 144 to pass through the installation box 141 and the bottom plate body 131 in sequence, and then connected to the nozzle 142 inside the water collection tank 11.

[0042] A manual quick-install diaphragm valve 145 is provided on the pipeline 143 in the installation box 141 .

[0043] A baffle 146 is also provided inside the water collecting tank 11 on the side facing the installation box 141 .

[0044] A movable baffle 147 is provided on the top of the installation box 141 .

[0045] The spray treatment component 1 is made of SUS304 material and is made by argon arc welding, and the weld needs to be pickled and passivated.

[0046] Combination Figure 4 and Figure 5 As shown, the filter cartridge 21 includes a rain cap 211, a third-stage filter cartridge 212, a second-stage filter cartridge 213 and a first-stage filter cartridge 214 which are sequentially connected from top to bottom.

[0047] A plurality of ventilation holes 121 are evenly distributed on the manhole cover 12 , and the bottom of the primary filter cartridge 214 is disposed in the corresponding ventilation holes 121 .

[0048] The rain cap 211 , the third-stage filter cartridge 212 , the second-stage filter cartridge 213 and the first-stage filter cartridge 214 , as well as the first-stage filter cartridge 214 and the vent hole 121 are all connected via a clamp 215 .

[0049] Ten rows of waist-shaped holes 216 are evenly distributed on the outer side of the third-stage filter cartridge 212 near the top, and three waist-shaped holes 216 are arranged in each row.

[0050] The bottom plates 217 of the tertiary filter cartridge 212 , the secondary filter cartridge 213 , and the primary filter cartridge 214 are all porous plates 217 .

[0051] The pore size of the porous plate 217 is 2 mm, and the porosity is 35%.

[0052] Two handles 218 are symmetrically provided on the outer sides of the third-stage filter cartridge 212 , the second-stage filter cartridge 213 , and the first-stage filter cartridge 214 .

[0053] The third-stage filter cartridge 212 , the second-stage filter cartridge 213 , and the first-stage filter cartridge 214 are used to be filled with chemical filter materials of different levels.

[0054] The filter cartridge 21 is made of 304 stainless steel, the inner side of the cartridge is painted with acid and alkali resistant anti-corrosion paint, and the welds are also subjected to pickling and passivation treatment.

[0055] The filter cartridge 21 of the breathable manhole cover of the present invention is installed on the ground. After the high-temperature sewage odor is sprayed and cooled by the spray assembly 14, it then passes through the porous plate 217 and enters the primary filter cartridge 214, the secondary filter cartridge 213, and the tertiary filter cartridge 212 step by step for chemical filtration, and then becomes odorless and is released into the atmosphere. The washed sewage flows into the inside of the water collection tank 11 and is finally discharged through the drain pipe 132.

[0056] The present invention adopts the method of washing with a water seal and adsorbing chemical filter materials. Through a highly coupled process, the water seal is formed by spraying with water to wash and cool the odor before it enters the chemical filter material, so that the odor concentration is reduced and the temperature is lowered. Compared with the original activated carbon adsorption, the back-end chemical filter material not only retains the physical adsorption capacity of the activated carbon but also increases the adsorption capacity of the chemical reaction, so that the same volume of adsorption filter material and the chemical filter material can adsorb more odor, thereby ensuring that the odor concentration at the manhole cover outlet meets the standard.

[0057] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
