Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to an odor control device for treating landfill leachate. Background Technology

[0002] During waste disposal operations, a large amount of leachate is usually generated. Because leachate is prone to evaporation and produces a large amount of harmful odor, the harmful substances contained in the odor can easily cause damage to the surrounding environment. Therefore, it is necessary to purify the odor generated by the leachate to reduce the odor.

[0003] Most existing odor control devices for landfill leachate treatment simply wait for the odor in the leachate to dissipate automatically before deodorizing the emitted gas, reducing work efficiency. Furthermore, most of them only treat the odor once before directly discharging it, which cannot ensure complete deodorization and can easily cause incompletely treated gas to pollute the environment.

[0004] Therefore, those skilled in the art have provided an odor control device for landfill leachate treatment to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an odor control device for landfill leachate treatment. This device can accelerate the emission rate of odors in leachate and automatically extract and treat them, further increasing the efficiency of odor treatment. It can also treat the odors three times to prevent the discharge of incompletely treated odors, which would pollute the environment, and further improve the deodorization effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an odor control device for landfill leachate treatment, comprising a filtrate tank, a connecting shaft rotatably disposed in the middle of the filtrate tank, a stirring roller fixedly connected to the outer wall of the connecting shaft, a motor fixedly disposed in the middle of one side of the filtrate tank, a first air pump fixedly disposed on one side of the upper end of the filtrate tank, a first suction pipe fixedly connected to the input end of the first air pump, and a gas collection hood fixedly connected to one side of the filtrate tank at the end away from the first air pump, wherein a first treatment tank, a second treatment tank and a third treatment tank are sequentially fixedly disposed on the upper end of the filtrate tank, and a first connecting pipe fixedly connected to the output end of the first air pump, with the end away from the first air pump extending into the interior of the first treatment tank;

[0007] A liquid storage tank is fixedly installed at the lower end of the first processing tank. A water pump is fixedly installed in the middle of one side of the first processing tank. A drain pipe is fixedly connected to the output end of the water pump. A water spray pipe is fixedly installed at the upper end of the first processing tank. A second air pump is fixedly installed at the upper end of the filtrate tank and located between the first and second processing tanks. A third air pump is fixedly installed at the upper end of the filtrate tank and located between the second and third processing tanks.

[0008] Furthermore, the output end of the motor is fixedly connected to the end of the connecting shaft;

[0009] Through the above technical solution, the motor drives the connecting shaft to rotate, which in turn drives the stirring roller to rotate, further accelerating the dissipation of odor in the leachate.

[0010] Furthermore, a nozzle is fixedly installed at the lower end of the water spray pipe;

[0011] The above technical solution allows for the uniform spraying and deodorization of odorous gases inside the first treatment chamber using spray nozzles.

[0012] Furthermore, the end of the drain pipe away from the water pump extends into the spray pipe, and the water pump input end is fixedly connected to a suction pipe, with the end away from the water pump extending into the storage tank.

[0013] Through the above technical solution, the water pump draws out the chemical reagents from the storage tank through the suction pipe and sprays the gas inside the first treatment tank to deodorize it. With the combined use of the suction pipe and the storage tank, the chemical reagents can be recycled, avoiding unnecessary waste.

[0014] Furthermore, the input end of the second air pump is fixedly connected to the second air suction pipe and the end away from the second air pump extends into the first processing box, the output end of the second air pump is fixedly connected to the second connecting pipe and the end away from the second air pump extends into the second processing box, and multiple ultraviolet lamps are fixedly installed inside the second processing box.

[0015] Through the above technical solution, the gas in the first processing box is transported to the second processing box by the second air pump, and the ultraviolet lamp generates ozone when it is working. The strong oxidizing property of ozone can help eliminate odors in the air.

[0016] Furthermore, the input end of the third air pump is fixedly connected to the third air suction pipe and the end away from the third air pump extends into the second processing box, the output end of the third air pump is fixedly connected to the third connecting pipe and the end away from the third air pump extends into the third processing box, and an activated carbon plate is fixedly installed in the middle of the third processing box.

[0017] The above technical solution uses a third air pump to transport the gas inside the second treatment chamber into the third treatment chamber. The activated carbon plate adsorbs the odor molecules in the gas inside the chamber, thereby achieving deodorization and further improving the deodorization effect.

[0018] Furthermore, the third processing box is provided with an exhaust port at its upper end, and a control panel is fixedly installed on one side of the front end of the filtrate box;

[0019] The above technical solution allows for the discharge of treated gas through an exhaust port, and a control panel facilitates the control of the device.

[0020] This utility model has the following beneficial effects:

[0021] 1. The present invention proposes an odor control device for landfill leachate treatment. The device uses a motor to drive the connecting shaft to rotate, which causes the stirring roller to rotate in the leachate tank, thereby accelerating the dissipation of odor in the leachate. The device also uses a first air pump to draw out the odor from the leachate tank and then transports it to the first treatment tank through a first suction pipe for automatic odor treatment. This further accelerates the efficiency of odor treatment and improves its convenience and practicality.

[0022] 2. The odor control device for landfill leachate treatment proposed in this utility model removes odor by spraying chemical reagents into the first treatment tank. With the cooperation of the storage tank and the suction pipe, the chemical reagents can be recycled to avoid unnecessary waste. When the odor passes through the second and third treatment tanks, the gases inside are deodorized by ultraviolet lamps and activated carbon plates, which further improves the deodorization effect.
