[0002] The circulating dust removal device is a highly efficient air purification equipment, which is designed to filter out harmful substances in the exhaust gas generated by industrial production or other processes in order to protect the environment. Its working principle is to introduce the dust-containing gas into the dust removal device, separate the dust from the gas by physical or chemical methods, discharge the dust-treated gas into the atmosphere, or recycle it, collect, store or recycle the separated dust, etc.

[0003] Circulating dust removal devices can be divided into many types according to different usage scenarios and characteristics, mainly including bag dust collectors, cyclone dust collectors, wet dust collectors and electrostatic precipitators. Bag dust collectors use paper bags or bags made of other materials to filter dust and other particulate matter. They are widely used in electricity, cement, coal and other industries with the characteristics of high efficiency, stability and reliability.

[0004] Most of the existing bag dust collectors use pulse jet cleaning technology. Through pulse jet control, the accumulated dust on the bags is removed and the filtering performance of the bags is restored. However, in the existing technology, cleaning is basically performed by pulse jetting on all the bags, and local pulse jet cleaning cannot be performed. Since the degree of dust accumulation on the bags in different areas of the dust collector box is different, pulse jetting on all the bags may easily cause a waste of resources.

9. The environmental protection circulating dust removal device according to claim 1, characterized in that: The collecting unit (4) comprises a material transfer box (41) and a screw rod (42), wherein the material transfer box (41) is fixedly connected to the bottom of the ash hopper (13), and the screw rod (42) is rotatably connected in the material transfer box (41). An ash inlet (411) is provided at the top of the material transfer box (41), and the ash inlet (411) is connected to the ash hopper (13). An ash outlet (412) is provided at one side of the material transfer box (41).

10. A method for using an environmentally friendly circulating dust removal device according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: Step 1: The gas containing dust particles is drawn into the dust removal box (11) from the dust gas inlet (14) by the suction force generated by the fan. When the dust-containing gas enters the dust collector, large particles will settle into the ash hopper (13) at the bottom of the dust removal box (11) due to the effect of gravity, thereby reducing the number of particles entering the bag (2133); Step 2: When the dust-containing gas passes through the bag (2133), the dust particles are trapped by the fiber material of the bag (2133), while the clean gas passes through the pores of the bag (2133) into the upper space of the flower plate (211), and is then discharged into the atmosphere from the clean gas outlet (12); Step 3: As time goes by, a dust layer will form on the bag (2133). As the dust accumulates, the dust on the bag (2133) becomes thicker and thicker, thereby blocking the pores of the bag (2133), reducing the airflow entering the bag (2133). At this time, the airflow sensor on the frame (2132) detects the change in airflow and displays it through the airflow meter (25). When a certain set value is reached, the control box (24) starts the corresponding spray pipe (223) to spray and clean the dust according to the position of the bag (2133) that has reached the set value; Step 4: The control box (24) simultaneously controls the motor (233) above the vertical plate (212) to rotate, thereby driving the rotating block (234) to rotate, so that the rotating block (234) collides and vibrates with the raised block (235) on the vertical plate (212), causing the vertical plate (212) to vibrate, thereby driving the plurality of cloth bags (2133) on the vertical plate (212) to vibrate; In step 5, the dust removed from the bag (2133) falls into the ash hopper (13), and falls into the material transfer box (41) from the ash inlet (411) along the ash hopper (13). The motor on the other side of the material transfer box (41) drives the screw rod (42) to rotate, and the rotation of the screw rod (42) drives the dust falling into the material transfer box (41) to move forward until the dust is discharged from the ash outlet (412) on one side of the material transfer box (41).
