Problems solved by technology
However, after the bag filter has been used for a period of time and before it reaches the level of dust removal, the wind speed has been reduced to a certain extent due to resistance, which reduces the dust removal efficiency of the cyclone dust collector, thereby affecting the dust removal efficiency of the overall dust removal equipment. Facts have proved that, One-half of the working time is due to the excessive wind resistance of the bag filter, which makes the cyclone dust collector in a low-efficiency state, making the equipment unable to perform effectively, and being in a sub-healthy working state for a long time, which increases dust emissions and energy consumption

The invention discloses a high-efficiency dust removal device, which includes a secondary cyclone dust collector for wind speed compensation. The air inlet of the auxiliary cyclone dust collector communicates with the air inlet of the main cyclone dust collector through a butterfly valve DF1. The air filter is equipped with a pressure difference relay CYJ1 for detecting the wind speed of its air inlet and air outlet, and a butterfly valve DF2 is installed on the pipeline between the air inlet of the main pulse blowback bag filter and the air outlet of the main cyclone dust collector. The main pulse blowback bag filter is equipped with a pressure difference relay CYJ2 for detecting the wind resistance of its inlet and outlet, and also includes a secondary pulse blowback bag filter with the same structure as the main pulse blowback bag filter. The air inlet of the pulse blowback bag filter is connected with the air outlet of the main cyclone dust collector through the butterfly valve DF3. It has the characteristics of high dust removal efficiency, high degree of automation, safety and reliability.
Description
technical field [0001] The invention relates to the technical field of dust removal devices. Background technique [0002] In order to improve the dust removal efficiency, the method of connecting the cyclone dust collector and the bag filter is usually used together. The dust removal mechanism of the cyclone dust collector is to make the dust-laden air flow rotate, and the dust particles are separated from the air flow by centrifugal force and captured. On the wall of the device, the dust particles fall into the ash hopper by gravity, which is used to filter out large particles of dust; after the filter material of the bag filter is used for a period of time, as the dust accumulates on the surface of the filter material, the dust collector The resistance will increase accordingly. When the pressure difference on both sides of the filter material is very big, some tiny dust particles which has attached to the filter material will be squeezed in and the dust collector efficie...
