Dust collector in woodworking factory

Introduction to the dust removal working principle of the woodworking factory dust collector: The dust generated by woodworking equipment in production is collected by the dust removal system's suction duct, and then enters the woodworking dust collector through the regulating disc valve and inlet duct. The dust is trapped outside the filter bag, and the clean gas is discharged into the atmosphere through the filter bag, induced draft fan, and chimney to meet the standard. This not only achieves the goal of recovering dust and purifying exhaust gas, but also ensures that all emission indicators meet the emission requirements.

The dust collector in the woodworking factory mainly consists of an ash hopper, a filter chamber, a clean air chamber, a bracket, a lifting valve, and a blowing and cleaning device. The dust collector in a woodworking factory is composed of three parts: a cyclone body, an ash hopper, and a snail shell (or air cap). It can be divided into five combinations according to the number of cylinders, including single cylinder, double cylinder, three cylinder, and six cylinder. Each combination has two types of air outlet forms: Type I horizontal air outlet and Type II (upper air outlet). For Type I double cylinder combination, there are also two types of combination forms: center inlet and outlet air and side inlet and outlet air. Type I single cylinder and three cylinder only have one type of air outlet when they are on the side, while four cylinder and six cylinder combination only have a center inlet and outlet air form. For various combinations of Type II, any of the inlet positions in Type I can be used. This dust removal equipment It has the characteristics of low resistance, good dust removal efficiency, large air processing volume, stable performance, small footprint, simple structure, practicality and low cost. It is suitable for various mechanical processing, metallurgical building materials, mining and mining of coarse dust Intermediate purification.

The dust collector in the woodworking factory requires three devices: pipeline system, fan system, and filtration system. In these three systems, the structure and function of different configurations are different, but the basic principle is the same, just like a person wearing a mask. The pipeline connects the woodworking machinery and the filtration system, and the fan works to create negative pressure suction in the pipeline. The main ones are the configuration of the fan and the performance of the filter bag.

The configuration of the fan is calculated based on the arrangement of the number of machines in the production workshop, which requires personnel to calculate the configuration so that the air volume of each machine's filter interface is consistent in order to achieve dust removal. Dust removal filter bags should be selected according to different environments, and the nature of dust generated in different woodworking workshops is different.

Most dust collectors in woodworking factories adopt centralized processing systems, which can save investment and facilitate management. During the production and processing of woodworking machinery in furniture factories, a high concentration of dust is generated, which seriously affects the working environment of the woodworking workshop. Therefore, our company has designed and produced a dust collector system specifically for furniture factory production workshops based on the characteristics of woodworking workshop dust. The system has a simple and compact structure, low steel consumption, and higher capture capacity compared to lighter fibrous dust such as sawdust, shavings, asbestos powder, tobacco, etc.

The principle of filtering and cleaning dust with a dust collector in a woodworking factory:

1. Filtering principle: Dust containing gas enters through the air inlet and collides with the inclined baffle. Most of the coarse particles in the gas are separated by inertial force and directly fall into the ash hopper. After passing through the ash hopper, the dust containing gas enters the filtering area of the filter cartridge in the middle box. The gas passes through the filter cartridge, and the dust is trapped outside the filter cartridge. The purified gas enters the upper box through the filter cartridge and is then discharged through the air outlet.

2. Principle of dust cleaning: As the filtering time continues, the dust layer on the filter cartridge continues to accumulate, and the resistance of the dust removal equipment continues to rise. When the equipment resistance rises to the set value or the operating time reaches the set value, the dust cleaning device starts to clean the dust. Firstly, the electromagnetic pulse valve of the blowing pipe is opened, and compressed air flows into the filter cartridge in a short time. Under the action of reverse airflow flushing, the dust attached to the outer surface of the filter cartridge is peeled off and falls into the ash hopper. After the dust cleaning is completed, the electromagnetic pulse valve is closed, and the filtering state is restored. The dust cleaning of each blowing pipe is carried out in sequence, starting from the first dust cleaning to the next dust cleaning cycle.

3. The dust collected through filtration and cleaning is intercepted and then falls into the ash hopper. It is then collected through the ash hopper and discharged into the ash unloading drawer. The equipment has a small volume, good filtration accuracy, and can be installed indoors.
