Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sewage treatment, and particularly relates to a biological deodorization device. BACKGROUND

[0002] The biological deodorization technology belongs to the sewage treatment technology, and is a method for degrading or converting pollutants in odor gas by using the metabolism of microorganisms. Usually, biological filter is paved with biological filler, and the biological filler provides a place for the growth and reproduction of microorganisms. Since the specific surface area of bamboo charcoal is large and the bamboo charcoal has certain acid and alkali resistance, the biological filler is usually bamboo charcoal as the filler, which is used as the attachment carrier of microorganisms.

[0003] REFERENCE Figure 1 The existing biological deodorization device comprises a deodorization tower 1, a biological filler 12 arranged in the deodorization tower 1, a water tank 13 arranged at the bottom, and the biological filler 12 is located above the water tank 13. An air inlet pipe 2 is arranged on the side wall of the deodorization tower 1 near the biological filler 12 and the water tank 13, and an air outlet pipe 3 is connected to the top of the deodorization tower 1. The odor gas is treated and purified by the biological filler 12 and then discharged from the air outlet pipe 3. A spraying mechanism 4 is arranged above the biological filler 12 in the deodorization tower 1, and the spraying mechanism 4 provides moisture or nutrient solution for the biological filler 12. The spraying mechanism 4 is connected to the water tank 13 through a circulating pipeline 5 to provide water source for spraying of the spraying mechanism 4. After long-time spraying and washing, the biological filler will be pulverized and broken, and a large amount of carbon residue and sludge will be deposited in the water tank 13. A filter 6 is arranged on the circulating pipeline 5 to filter the carbon residue and sludge.

[0004] In actual operation, it is found that the carbon residue and sludge are easy to block the drain of the water tank 13 or the connection between the water tank 13 and the circulating pipeline 5, which causes the poor drainage effect of the water tank 13 and the poor spraying effect of the spraying mechanism 4, and affects the treatment effect of the biological deodorization device on odor gas. In severe cases, the deodorization device needs to be stopped for manual removal of the carbon residue and sludge. CONTENT OF THE UTILITY MODEL

[0005] One of the purposes of the application is to provide a biological deodorization device which can ensure the treatment effect on odor gas.

[0006] To achieve the above-mentioned purposes and other related purposes, the application provides a biological deodorization device, which comprises a deodorization tower, a spraying mechanism, a circulating pipeline and a sludge collecting part.

[0007] The deodorization tower comprises a support frame, an internal water tank, an air inlet pipe and an air outlet pipe. The support frame is arranged in the deodorization tower and used for supporting the biological filler. The internal water tank is arranged at the bottom of the deodorization tower and below the support frame. The air inlet pipe is arranged on the side wall of the deodorization tower between the support frame and the internal water tank. The air outlet pipe is arranged at the top of the deodorization tower.

[0008] The spraying mechanism is installed inside the deodorization tower and located above the support frame;

[0009] The circulation pipeline is located outside the deodorization tower, and the spraying mechanism is connected to the built-in water tank through the circulation pipeline;

[0010] The mud collection section is a box structure, and the mud collection section is connected to the built-in water tank;

[0011] The bottom of the built-in water tank is an inclined surface, and the connection between the mud collection part and the built-in water tank is located at the lowest point of the bottom of the built-in water tank.

[0012] This application has at least the following beneficial effects:

[0013] This invention, by incorporating a sludge collection section, prevents carbon slag and silt from clogging the drain outlet of the built-in water tank or the connection between the built-in water tank and the circulation pipeline. The ramp and flushing pipeline design ensure that carbon slag and silt are quickly collected in the sludge collection section.

[0014] This utility model also provides an external water tank connected to the sludge collection section, and a filter assembly between the sludge collection section and the external water tank. This facilitates the spraying mechanism to draw water from the external water tank through the circulation pipe, avoiding the situation where drawing water directly from the internal pipe would cause carbon residue and sludge in the internal water tank to enter and block the circulation pipe due to the high-speed water flow of the flushing pipe.

[0015] By forming a connecting structure between the external water tank, the sludge collection section, and the internal water tank, carbon residue and sludge can be easily fed into the sludge collection section with the water. Attached Figure Description

[0025] Reference Figures 2 to 4 This embodiment provides a biological deodorization device, including a deodorization tower 1, a spraying mechanism 4, a circulation pipeline 5, and a sludge collection section 9.

[0026] The deodorization tower 1 can be a rectangular structure, for example, 5 meters long and wide, and 3.5 meters high. The deodorization tower 1 includes a support frame 7, an internal water tank 8, an air inlet pipe, and an exhaust pipe (not shown in the figure). The support frame 7 is located inside the deodorization tower 1 and is used to hold the biological packing material. The height of the support frame 7 can be 1.05 meters. The internal water tank 8 is located at the bottom of the deodorization tower 1 and below the support frame 7. The distance between the liquid level in the internal water tank 8 and the bottom surface of the support frame 7 is not less than 0.482 meters.

[0027] The air inlet pipe 2 is located on the side wall of the deodorization tower 1 between the support frame 7 and the built-in water tank 8, and is used to introduce malodorous gases. The exhaust pipe 3 is located at the top of the deodorization tower 1, and is used to discharge the malodorous gases that have been treated and purified by the biological packing material.

[0028] The spraying mechanism 4 is installed inside the deodorization tower 1 and above the support frame 7. The spraying mechanism 4 provides water or nutrient solution to the biological packing material, providing the water or nutrients needed for the survival of the microorganisms in the biological packing material. The height difference between the spraying mechanism 4 and the biological packing material can be 0.75 meters.

[0029] The circulation pipe 5 is located outside the deodorization tower 1. The spraying mechanism 4 is connected to the built-in water tank 8 through the circulation pipe 5 to circulate the water required for the spraying mechanism 4. The connection between the built-in water tank 8 and the circulation pipe 5 is located on the side wall of the built-in water tank 8. The circulation pipe 5 includes a sewage branch, on which a sewage discharge valve 16 is installed.

[0030] The sludge collection section 9 is connected to the built-in water tank 8. Carbon slag and silt can slide from the built-in water tank 8 into the sludge collection section 9 with the sprayed water flow, avoiding the carbon slag and silt from clogging the drain outlet of the built-in water tank 8 or the connection between the built-in water tank 8 and the circulation pipe 5.

[0031] The mud collection section 9 has a box-like structure. The box-like structure can be either regular or irregular in shape.

[0032] In some embodiments of this application, reference is made to Figure 2 The sludge collection section 9 has an L-shaped structure, including a horizontal section and a vertical section. The horizontal section is connected to the built-in water tank 8 and extends from the bottom of the deodorization tower 1 away from the deodorization tower 1. The vertical section is connected to the horizontal section and is at a predetermined distance from the deodorization tower 1 in the horizontal direction, so that the carbon residue and sludge in the sludge collection section 9 can be cleaned manually from the outside of the deodorization tower 1. The side wall of the vertical section is provided with an overflow port, so that the water or nutrient solution sprayed by the spraying mechanism 4 that exceeds the safe capacity of the built-in water tank 8 flows through the horizontal and vertical sections of the sludge collection section 9 in sequence and is discharged from the overflow port.

[0033] Reference Figure 3 The sludge collection section 9 has a T-shaped structure. The left side of the T-shaped structure is located at the bottom of the deodorization tower 1, and the right side of the T-shaped structure is located outside the deodorization tower 1. The T-shaped design prevents the carbon residue and sludge on the right side of the T-shaped structure from flowing back to the left side of the T-shaped structure and the built-in water tank 8.

[0034] In some embodiments of this application, the distance from the lowest point of the mud collection section 9 to the lowest point of the built-in water tank 8 is 0.5 meters.

[0035] In some embodiments of this application, the volume of the sludge collection section 9 is 0.2% of the volume of the biological packing material of the deodorization tower 1.

[0036] The bottom or side wall of the sludge collection section 9 is provided with a drain outlet for discharging carbon slag and silt from the sludge collection section 9. (Refer to...) Figure 4 The sewage outlet is connected to the circulation pipeline 5 through the sewage pipe 17, and the sewage pipe 17 is equipped with a sewage valve 18.

[0037] To allow the slag and silt to slide quickly from the built-in water tank 8 into the sludge collection section 9 with the sprayed water, a slope is laid at the bottom of the built-in water tank 8. The connection between the sludge collection section 9 and the built-in water tank 8 is located near the lowest point of the slope of the built-in water tank 8. In one example, the slope of the built-in water tank 8 is 7% to 30%. In one example, the height of the slope can be 35 cm.

[0038] Furthermore, a slope can also be provided at the bottom of the mud collection section 9. The slope of the mud collection section 9 is 7% to 30%. In one example, the slope of the mud collection section 9 is in the same direction and has the same slope as the slope of the built-in water tank 8. In one example, the height of the slope of the mud collection section 9 is 15 cm.

[0039] When a slope is provided, the sewage outlet of the sludge collection section 9 is located at the lowest point of the slope of the sludge collection section 9, which facilitates the deposition of carbon slag and silt near the sewage outlet for easy discharge.

[0040] To prevent carbon residue and sludge from accumulating in the built-in water tank 8, the biological deodorization device also includes a flushing pipe. The side wall of the built-in water tank 8 has flushing holes, which, in the case of a slope, are located above the highest point of the slope, for example, 20 cm above the top of the slope. Multiple flushing holes can be arranged horizontally, spaced 30–100 cm apart. The flushing pipe 21 connects to the flushing holes, spraying a high-speed stream of water onto the slope of the built-in water tank 8 to flush away the carbon residue and sludge. The flushing pipe 21 can be set to perform timed flushing.

[0041] The water for the flushing pipe can come from the outside or from the built-in water tank 8 of the deodorization tower 1 to save water. The inlet of the flushing pipe is directly connected to the built-in water tank 8, or it can be connected to the circulation pipe 5 to obtain water from the built-in water tank 8. A flushing valve 15 is provided between the flushing pipe 21 and the circulation pipe 5.

[0042] In this embodiment, the biological deodorization device also includes an external water tank 10. The spraying mechanism 4 is connected to the external water tank 10 through the circulation pipe 5. That is, the spraying mechanism 4 can draw water from the external water tank 10 without directly drawing water from the internal water tank 8, thus avoiding the carbon residue and sludge in the internal water tank 8 from entering and blocking the circulation pipe 5 with the high-speed water flow of the flushing pipe.

[0043] An external water tank 10 is located outside the deodorization tower 1 and is connected to the sludge collection section 9. A filter assembly 11 is installed at the connection between the external water tank 10 and the sludge collection section 9 to intercept carbon residue and sludge from entering the external water tank 10 from the sludge collection section 9. The height of the external water tank 10 can be 1.2 meters.

[0044] The filter assembly 11 includes a filter plate and a filter screen. The filter plate is installed at the connection between the external water tank 10 and the sludge collection section 9. The filter screen is detachably mounted on the filter plate for easy cleaning and replacement.

[0045] Reference Figure 3 The external water tank 10 and the sludge collection section 9 are arranged side by side and horizontally. One side of the external water tank 10 and one side of the sludge collection section 9 share the same virtual surface, on which the filter plate is laid. The length of the filter plate can be 1.2 meters. Because the filter plate and filter screen cover a large area, when part of the filter screen is blocked, it does not affect the water flow from the sludge collection section 9 into the external water tank 10, ensuring that the circulation pipeline 5 can smoothly obtain the required water flow volume, and avoiding a deterioration in the spraying effect of the spraying mechanism 4, which would affect the odor treatment effect of the biological deodorization device. In the absence of an external water tank 10, the internal water tank 8 is equipped with a drain outlet, which is located above the sludge collection section 9 to reduce the entry of carbon residue and sludge into the drain outlet.

[0046] Reference Figure 2 An external water tank 10, a sludge collection section 9, and an internal water tank 8 are sequentially connected to form a communicating vessel structure, with the liquid level in the internal water tank 8 flush with the liquid level in the external water tank 10. Due to the communicating vessel structure, carbon residue and sludge can easily flow into the sludge collection section with the water. The filter plate and filter screen ensure that the circulation pipe 5 can smoothly obtain the required water flow, and also ensure the normal water inlet and outlet of the external water tank 10. The top of the external water tank 10 can be opened for easy external water replenishment. The drain pipe 19 of the external water tank 10 can be connected to the circulation pipe 5, and a drain valve 20 is provided on the drain pipe 19.

[0047] Here is an example of the workflow for cleaning carbon residue and sludge from the built-in water tank 8:

[0048] Open the spray valve 14 of the circulation pipe 5 and the drain valve 20 of the drain pipe 19 connected to the external water tank 10; the spray mechanism 4 sprays water onto the biological filler. The water flow, carbon residue and sludge generated by the spraying flow into the built-in water tank 8 and then into the sludge collection section 9. The clean water filtered by the filter assembly 11 enters the external water tank 10, and then the clean water provided by the external water tank 10 passes through the drain pipe 19 and the circulation pipe 5 to be supplied to the spray mechanism 4.

[0049] Keep the drain valve 20 open, close the spray valve 14 of the circulation pipe 5, and open the flush valve 15 of the flush pipe 21 so that the water in the circulation pipe 5 flows through the flush pipe 21 to flush the built-in water tank 8, so that the carbon residue and sludge cannot stay in the built-in water tank 8, but continuously enter the sludge collection section 9.

[0050] Close the drain valve 20 and the flush valve 15, open the drain valve 18 of the sewage pipe 17 and the drain valve 16 on the sewage branch of the circulation pipe 5, and the carbon slag and silt accumulated in the sludge collection section 9 will be continuously discharged from the sewage outlet through the drain valve 18 and the sewage branch.

[0051] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
