Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a pulse bag dust collector. Background Technology

[0002] In the industrial production sector, the purification of dust-laden gases is a crucial aspect of environmental protection and production safety. Pulse baghouse dust collectors, relying on the core principle of bag filtration, achieve gas-solid separation through the interception of dust by fiber fabrics, making them one of the mainstream dust removal solutions. However, in actual operation, the implementation effect of the working principle of existing equipment still has significant limitations.

[0003] In the dust removal process, traditional equipment relies on a single pulse airflow to clean the bags. Although high-pressure airflow can generate strong vibrations, it is easy to cause excessive wear on the bags. Low-pressure airflow, on the other hand, is not effective due to insufficient impact force, resulting in incomplete cleaning. Simple airflow vibration is insufficient to remove stubborn dust accumulated on the surface, which accelerates the clogging of the bag pores and causes a continuous decline in filtration efficiency. Frequent shutdowns for dust removal are required to maintain basic functions. This single dust removal method is not well adapted to the bag filtration principle, which has become a key issue restricting the stable operation of the equipment. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a pulse bag dust collector. It has the following beneficial effects:

[0015] 1. The dust collector filters and separates dust-laden gas through the dust collector bag, effectively trapping dust to purify the gas. At the same time, the electromagnetic pulse valve drives the pulse tube to create airflow vibration, which, together with the fan impeller driving the knocking rod to mechanically knock, forms a composite dust removal structure.

The water-collecting box can also be easily pulled out for cleaning to achieve centralized dust treatment. This structural design also improves the convenience of inspection, replacement and maintenance of internal components (such as dust collector bags, filter plates and water-collecting boxes), which helps to reduce equipment operation and maintenance costs.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a pulse bag dust collector, including a base plate 1, a support frame 2 fixedly connected to the surface of the base plate 1, a dust collector 3 fixedly connected to the top of the support frame 2, an inlet pipe 5 and an exhaust pipe 6 respectively provided on both sides of the dust collector 3, and a partition plate 7 fixedly connected to the inner wall of the dust collector 3. Two annular grooves 8 are opened on the surface of the partition plate 7, and a dust collector bag 9 is provided at the lower end of the two annular grooves 8. A dust collector pipe 12 is provided inside the dust collector bag 9, and a pulse pipe 11 is fixedly connected to the top of the dust collector pipe 12. An electromagnetic pulse valve 10 is provided at one end of the pulse pipe 11, and the electromagnetic pulse valve 10 is installed on the side wall of the dust collector 3. When dust-laden gas enters the dust collector 3 through the inlet pipe 5, it is filtered by the dust collector bag 9. The dust in the gas is trapped by the fiber structure of the bag, and the purified gas flows upward through the bag and is finally discharged from the exhaust pipe 6, thus separating the dust from the gas and completing the basic dust removal task. When too much dust adheres to the surface of the bag, the electromagnetic pulse valve 10 (model DMF-Z-40S) is opened. The high-pressure airflow is injected into the inside of the bag at high speed through the pulse pipe 11 and the dust collector pipe 12, causing the bag to expand and vibrate instantly, shaking off the surface dust, thereby restoring the filtration capacity of the bag and avoiding the decrease in dust removal efficiency due to blockage.

[0025] Reference Figure 2 and Figure 3As shown in this embodiment: a water box 14 is provided below the dust collector bag 9, and the water box 14 is slidably connected to the inner wall of the dust collector box 3. A filter plate 13 is provided on the inner wall of the annular groove 8, and the filter plate 13 is located above the dust collector bag 9. The water box 14 slidably connected below the dust collector bag 9 can accurately collect the dust shaken off the bag, so that the dust and the water in the water box 14 can mix and settle. The sliding design makes it easy to pull out for cleaning, which is convenient for centralized dust treatment. At the same time, the filter plate 13 located on the inner wall of the annular groove 8 above the dust collector bag 9 can block the dust generated when cleaning the dust collector bag 9, prevent it from being discharged from the exhaust pipe 6, and enhance the dust removal effect.

[0026] Reference Figure 3 and Figure 4 As shown, specifically, the pulse tube 11 has a drive chamber 15 inside, and a rotating shaft 17 is rotatably connected inside the drive chamber 15. A fan impeller 16 is fixedly connected to the top of the rotating shaft 17, and a striking rod 18 is fixedly connected to the lower end of the rotating shaft 17. The number of striking rods 18 is set to three sets, and the striking rods 18 are in contact with the dust collector bag 9. The front of the dust collector box 3 is hinged with a box door 4, and a handle is provided on the surface of the box door 4. The fan impeller 16 rotates with the airflow, and the rotating shaft 17 drives the three sets of striking rods 18 to rotate synchronously, continuously striking the dust collector bag 9. At the same time, in conjunction with pulse jet cleaning, it can more thoroughly remove stubborn dust on the surface of the bag, especially for adhesive dust that is difficult to remove by pulse, further improving the dust removal effect. At the same time, the box door 4 hinged on the front of the dust collector box 3 and the handle on the surface make it easy to open the box to inspect, replace or maintain the dust collector bag 9, filter plate 13, water box 14 and other components inside.

[0027] Working principle: Dust-laden gas first enters the dust collection box 3 through the inlet pipe 5, and then enters the dust collection bag 9. The dust is trapped by the fiber structure of the bag, and the purified gas penetrates the bag and flows upward, finally being discharged from the exhaust pipe 6, completing the basic filtration and separation. When there is a lot of dust on the surface of the dust collection bag 9, the electromagnetic pulse valve 10 is activated, controlling the pulse tube 11 to release high-pressure airflow, which is sprayed into the inside of the bag through the dust collection pipe 12, causing the bag to expand and vibrate instantly, shaking off the surface dust. At the same time, the impeller 16 inside the pulse tube 11 rotates with the airflow, driving the three sets of striking rods 18 to rotate synchronously through the rotating shaft 17, continuously striking the bag. The combination of mechanical striking and pulse jet blowing thoroughly removes the sticky and stubborn dust, ensuring that the filtration capacity of the bag is restored. The shaken-off dust falls into the water box 14 below the bag, where the water mixes and settles to prevent the dust from being stirred up and causing secondary pollution. The water box 14 is slidably connected to the inner wall of the dust collection box 3, and can be pulled out for cleaning at any time, achieving centralized dust treatment.
