Method for operating filtering device

Abstract

The invention discloses a method for operating filtering device. The filtering device comprises a filter tube, a filtering mechanism and a controller, the filtering mechanism is arranged in the filtertube, a pressure-measuring sealing mechanism is arranged at one end of the filter tube, an oil cylinder is arranged at the other end of the filter tube, and the power end of the oil cylinder pressesthe filtering mechanism to the working side of the pressure-measuring sealing mechanism; one side of the filter tube is connected with a liquid outlet tube, an anti-blocking dirt discharging mechanismis arranged at one side, away from the liquid outlet tube, of the filter tube, the anti-blocking dirt discharging mechanism is connected with a liquid inlet tube, a vacuum water tank is provided witha vacuum pump, a water discharging port and a pressure gauge, and the anti-blocking dirt discharging mechanism is communicated with the filter tube and cooperates with the filtering device. The method for operating filtering device generates a negative pressure by the vacuum pump to make wastewater quickly pass through the filtering mechanism, so the rapid removal efficiency of particulate matters in the wastewater is increased, thereby the filtration speed is increased, and the wastewater recycling rate is increased.

Description

technical field [0001] The invention belongs to the field of filtering devices, and in particular relates to an operating method of the filtering device. 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 ignore...

AI Technical Summary

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] However, 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 existing equipment directly transports wastewater to the degradation tank. Although the direct degradation has a fast wastewater transport speed and does not affect the exhaust gas emission efficiency, the wastewater is prone to exceed the discharge standard; and due to the harmful The substance content is not the same, so that a single filter device cannot complete its filtering task
