A negative pressure filter system

Abstract

The invention discloses a negative pressure filtration system, which comprises a spray tower, a liquid guide pipe, an air guide pipe and at least two negative pressure filter devices connected in series, and the spray tower is sequentially connected with a drying device through the air guide pipe , adsorption device, plasma generator, blower fan and exhaust pipe, the bottom of the spray tower is connected with the negative pressure filter device through the guide pipe, the guide pipe is provided with an electric ball valve, and the inside of the spray tower is located There are two liquid level sensors to control the liquid level under the smoke pipe; the negative pressure filter device includes a filter tube, a filter device and a controller, the filter device is set in the filter tube, and one end of the filter tube is provided with a pressure gauge Sealing mechanism, the other end of the filter tube is hinged with an oil cylinder; a negative pressure filtration system of the present invention generates negative pressure through a vacuum pump, so that wastewater can quickly pass through the filter device, improving the rapid removal efficiency of particulate matter in wastewater, thereby speeding up filtration Speed ​​and can improve the recycling rate of waste water.

Description

technical field [0001] The invention belongs to the field of filtering devices, and in particular relates to a negative pressure filtering system. Background technique [0002] At present, there are three main sources of air pollution: Industry: Industry is an important source of air pollution. The pollutants discharged into the atmosphere by industry are various and complex in nature, including smoke, sulfur oxides, nitrogen oxides, organic compounds, Halides, carbon compounds, etc., some of which are smoke and some are gases; domestic stoves and heating boilers: a large number of civilian stoves and heating boilers in cities need to consume a lot of coal, and coal will release a lot of dust, sulfur dioxide, carbon dioxide, and carbon monoxide during combustion Such harmful substances pollute the atmosphere, especially when heating in winter, often make the polluted area filled with smog and make people cough, which is also a source of pollution that cannot be ignored; tran...

Problems solved by technology

High-concentration organic wastewater has the characteristics of high concentration, complex composition, poisonous and harmful, and if it is directly discharged into the water body without treatment, it will seriously pollute the water body environment

[0004] After water degradation, it needs to be comprehensively treated according to its characteristics, such as biodegradation and chemical degradation, but these degradation methods cannot meet the existing production speed, and most of them are caused by the inability to control the concentration of harmful substances in wastewater during the degradation process. Most of the equipment directly transports waste water to the degradation tank. Although the waste water transport speed of direct degradation is fast and does not affect the emission efficiency of waste gas, the waste water is easy to discharge beyond the standard; and due to the harmful substances in each filtered waste liquid The content is not the same, making a single filter device unable to complete its filtering task
