Abstract
Description
Technical Field
[0001] This utility model relates to a waste gas treatment device for solid waste treatment equipment, belonging to the field of waste gas treatment equipment. Background Technology
[0002] Solid waste treatment involves multiple industrial sectors such as construction and chemical industry. During the solid waste treatment process, the dust-containing waste gas and the polluting waste gas generated are difficult to treat. Common solid waste treatment equipment is difficult to separate and treat the waste gas mixed in the environment. It is necessary to have a closed treatment room to prevent the waste gas from leaking into the atmosphere, which has high construction costs and is very harmful to workers. Summary of the Invention
[0003] Based on the problems described in the background, the problem that this utility model aims to solve is:
[0004] Common solid waste treatment equipment is difficult to separate and treat waste gas mixed in the environment. It requires a closed treatment room to prevent waste gas from leaking into the atmosphere, which is costly to build and poses a great hazard to workers.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A waste gas treatment device for solid waste treatment equipment includes a negative pressure chamber, a treatment tank, and a discharge tank. The solid waste treatment equipment is installed in the negative pressure chamber. An air extraction pump is installed at the top of the negative pressure chamber. The air extraction pump is connected to the bottom side of the treatment tank through an air extraction pipeline. A water mist sprayer is installed inside the treatment tank. The top of the treatment tank is connected to the side of the discharge tank through a pipeline. A discharge port is installed at the top of the discharge tank. A sewage discharge detector is installed at the discharge port. The sewage discharge detector is electrically connected to the water mist sprayer.
[0007] Negative pressure chambers are specially designed for solid waste treatment devices. Because they have air pumps that draw air out of the chamber, creating negative pressure, clean air enters the chamber through the doors and gaps. This ensures that the waste gas generated by the solid waste treatment device will not diffuse into the environment and cause pollution due to insufficient sealing of the chamber.
[0008] The exhaust gas detector monitors the dust and pollution index in the exhaust gas in real time. When the detected value changes, the spray volume of the water mist sprayer is adjusted, thereby controlling and stabilizing the parameters of the exhaust gas.
[0009] Preferably, multiple treatment tanks are arranged in series. This series arrangement increases the contact time between the exhaust gas and the spray water, improving the upper limit and effectiveness of dust and pollution removal. The spray volume can be adjusted according to operating conditions and load, ensuring treatment effectiveness while saving water and chemicals.
[0010] Preferably, the emission outlet is equipped with a sampler. The sampler allows for regular sampling and testing of the emitted gas, calibrating the effectiveness of the emission detector, and preventing leakage of waste gas that could damage the environment.
[0011] The beneficial effects of this utility model are:
[0012] 1. This utility model provides a negative pressure environment for solid waste treatment devices, ensuring that waste gas will not overflow into the environment and that waste gas can be centrally treated.
[0013] 2. This utility model controls the water mist sprayer through a sewage discharge detector, making the equipment operation more stable. By sampling and periodically testing, the sewage discharge detector is calibrated to ensure its normal operation and reduce the occurrence of over-discharge accidents. Attached Figure Description
