The dust-containing gas enters the ash hopper through the air inlet and enters the dust bag room through the open flange. The dust-containing gas is filtered through the filter bag and becomes clean air, enters the clean air chamber, and is then discharged through the clean air chamber. The air outlet is discharged by the fan. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the bag dust collector to continue to rise. In order to ensure that the equipment resistance does not exceed the limit and the bag dust collector can work intermittently, the dust on the filter bag needs to be removed regularly.
The program controller starts the pulse valve in a timed and sequential manner, so that the compressed air (~) in the bag is ejected from the hole of the blow pipe (called primary air) through the venturi tube to induce several times the primary air. The surrounding air (called secondary air) enters the filter bag, causing the dust bag to expand rapidly in an instant, and shakes off the dust with the opposite direction of the air flow. The dust attached to the surface of the bag quickly breaks away from the filter bag and falls into the ash hopper (or ash hopper). bin), the dust is discharged from the dust discharge valve to achieve the purpose of dust cleaning.
The reasonable design of the dust collector is the key to the long-term reliable and stable operation of the system. Our company's anti-condensation low-resistance cleaning pulse dust collector has completely solved the common problems of condensation, hardening and high resistance that have long been common in domestic dust collectors, and can run stably for a long time. It ensures the stability of the system air volume. <
Dust collector is a type of dust removal device. The desettling mechanism is to make the dust-containing air flow rotate, use centrifugal force to separate the dust particles from the air flow and capture them on the wall, and then use gravity to make the dust particles fall into the ash hopper. Cyclone dust collectors began to be used in 2007 and have developed into many types. According to its flow entry mode, it can be divided into two types: tangential entry type and axial entry type. Under the same pressure loss, the latter can handle approximately twice as much gas as the former, and the gas flow is evenly distributed. Ordinary cyclone dust collectors are composed of a simplified cone and an intake and exhaust pipe. The cyclone dust collector has a simple structure, is easy to manufacture, install, maintain and manage, and has low equipment investment and operating costs. It has been widely used to separate solid and liquid particles from air flows, or to separate solid particles from liquids. Under normal operating conditions, the centrifugal force acting on particles is ~ times that of gravity, so the efficiency of the cyclone dust collector is significantly higher than that of the gravity settling chamber. Most of them are used to remove the above particles. The parallel multi-tube cyclone dust collector device also has ~% dust removal efficiency for the particles. The cyclone dust collector is constructed of special metal or ceramic materials that are resistant to high temperature, abrasion and wear, and can operate under conditions of temperatures up to ℃ and pressures up to 100°C. Considering the technical and economic aspects, the pressure loss control range of cyclone dust collector is generally ~.
