Water cycle automatic dust removal method and device for wood-based panel production

Abstract

The invention discloses a water circulation automatic dust removal method and device for artificial board production. Dust is settled into a flocculation buffer pool in the simplest spraying mode, after flocculent settling, a purified water tank is used for filtering clean water which can be recycled for spraying, the purified water tank also has the backwashing function, when a certain amount of dirt is accumulated at the bottom of the tank, a controller turns on a water valve at the bottom of the tank, powerful potential energy of water at the upper portion inside the tank is used for thorough backwashing of the dirt below the water, sewage obtained through backwashing is coarsely filtered through a solid-liquid separator, the remaining sewage can be drained into the flocculation buffer pool to be circulated and filtered to be used again, full-automatic control of the controller is adopted, a large amount of dust can be efficiently processed, sewage obtained after solid-liquid separation is conveyed back to a flocculation settling tank to be filtered again and recycled, water resource waste and secondary environment pollution are avoided, the circulating purification function is achieved, and zero-drainage of sewage is achieved.

Description

technical field [0001] The invention relates to a dust removal technology, in particular to an automatic dust removal device and a dust removal method for removing dust from wood-based panels. Background technique [0002] Commonly used dust removal devices in the industry include wet dust removal devices, electrostatic dust removal devices, and cyclone dust removal devices. There has always been a problem of environmental pollution in the production of wood-based panels. The particles produced in the exhaust gas of wood-based panels are basically wood dust. Wood dust has large particles, no chemical reaction, a large flow rate, and is easy to separate and collect. Therefore, cyclone separators and bag dust collectors are generally used. container for recycling. Although this type of device is convenient for dust removal and has relatively high efficiency, there are actually many problems such as the exhaust gas cannot meet the standard, the filter bag is easy to clog, the ...

AI Technical Summary

Problems solved by technology

Although this type of device is convenient for dust removal and has relatively high efficiency, there are actually many problems such as the exhaust gas cannot meet the standard, the filter bag is easy to clog, the energy utilization rate is not high, and the working conditions of the workers are poor.

Ordinary wet dust removal devices also have some problems. The biggest problem is that the sewage from dust treatment is not recycled, resulting in a large amount of waste of water resources and secondary pollution to the environment.
