How to prevent the explosion of the dust collector

In the bag type dust remover dealing with waste gas of wood sawdust boiler, rice husk boiler, aluminum regenerator and smelting furnace, the burning dust in the furnace may enter the box with the wind pipe air flow, and causes the dust on the filter cloth to fire and cause the accident. In the bag type dust remover dealing with the waste gas of the wood sawdust boiler, the rice husk boiler, the aluminum regenerative furnace and the smelting furnace. The burning dust in the furnace is likely to enter the box with the air pipe air flow, causing the dust accumulated on the filter cloth to catch fire, resulting in an accident.

To prevent Mars from entering the bag filter, the following measures should be taken.

1. Set the preduster and the cooling pipe. The picture shows that a cyclone or inert dust collector is used as a pre dust collector to trap coarse particles and Mars. In this way, tiny particles of Mars are not easy to trap. In most cases, particulate dust can burn out before entering the dust collector. After the predust collector is installed, the cooling pipe is set up, and the flow rate in the pipe is controlled to keep it as low as possible. This is a relatively reliable technical measure, which enables the gas to have sufficient residence time in the pipe.

2. Cooling spray tower. A gas cooling method with direct water spray in advance. In order to ensure the safe fire prevention of dusty gas in bag filter, the cooling water consumption is controlled. Most of the burning dust can be cooled by contact with combustion dust that has not been exposed to the water can be cooled. It should have the necessary space and residence time.

Under special circumstances, the combination of spray tower, cooling tube and predust collector is used to prevent Mars from mixing.

3.Installing Mars trapping devices on pipelines is a simple and feasible method. In addition, when Mars passes through the trap, it can send out electrical signals and alarm. At the same time, stop operation or change gas circuit and so on.
