Description

A low-pressure pulse bag filter

technical field

The utility model relates to the technical field of bag dust collectors, in particular to a low-voltage pulse bag dust collector.

Background technique

The equipment that separates dust from flue gas is called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production. During use, it is necessary to prevent the gas from cooling below the dew point in the bag room, especially when using the bag filter under negative pressure. Because the shell often has air leaking in, the temperature of the gas in the bag chamber is lower than the dew point, and the filter bag will be damp, so that the dust is not loose, but adheres to the filter bag stickyly, blocking the fabric holes and causing cleaning. If the ash fails, the pressure drop of the dust collector is too large, and it cannot continue to operate, and some paste bags cannot be removed. |For the bag filter, its operating temperature depends on two factors, the first is the maximum temperature of the filter material, and the second is that the gas temperature must be above the dew point temperature. Due to the large selection of glass fiber filter materials, the maximum operating temperature can reach 280°C. Measures must be taken to cool the gas above this temperature, and measures to raise the temperature must be taken to the gas below the dew point temperature. For the bag filter, the relationship between the operating temperature and the dust removal efficiency is not obvious, which is different from the electrostatic precipitator. For the electrostatic precipitator, the change of temperature will affect the specific resistance of the dust and affect the dust removal efficiency. In order to improve the dust cleaning effect and continuous working ability, the bag filter is divided into several chambers in the design, and each chamber has a main air valve to control whether the chamber is in the filtering state or in the filtering state. When a room is cleaned or maintained, the main air valve must be closed and the filter is stopped. The air volume is completely borne by other rooms. The total filter area of other rooms is called the net filter area. That is to say, the net filter area is equal to the total filter area minus the sum of the filter areas of the number of cleaning rooms and maintenance rooms that must be maintained during operation. The bag filter is a relatively common dust removal equipment for enterprises.

There are some defects in the existing bag filter during use. For example, a large amount of dust will block the ash outlet during use, which will cause the filter to not work normally and affect the work efficiency.
