Embodiment 1

[0024] Such as figure 1 As shown, a screw-on double-layer mixed dust bag is composed of an outer bag 1 and an inner bag 2 .

[0025] The outer bag 1 includes an outer dust cloth 13, an outer frame 8, and an outer retaining ring 5. The outer dust cloth 13 is made of materials such as polyester, polypropylene or fiberglass, and is sewn into a bag shape and is fitted on the outer frame 8. The outer frame 8 top is welded or is installed with an outer retaining ring 5 with screws, and the inner side of the outer retaining ring 5 is machined with internal threads.

[0026] The inner bag 2 includes an inner dust cloth 12, an inner skeleton 7, an inner retaining ring 4, a vibrating motor 10, an electrostatic precipitator fence 3, a pulse type recoil nozzle 6, a base plate 11, and a motor cover 9. Inner dust-removing cloth 12 also adopts materials such as dacron, polypropylene fiber or fiberglass to make, and is sewn into bag shape, and suits on the inner skeleton 7. An inner retaini...

Embodiment 2

[0037] Such as figure 2 As shown, a screw-in double-layer mixed dust bag includes a dust cloth, an inner retaining ring 4, an outer retaining ring 5, an inner frame 7, an outer frame 8, a vibration motor 10, a base plate 11, and a motor cover 9. Inner bag 2 and outer bag 1 are made of dust-removing cloth and inner and outer frame 8 respectively, and inner frame 7 and outer frame 8 are all made grid shape by fine iron wire, can energize and carry out electrostatic dust removal. The tops of the inner bag 2 and the outer bag 1 are respectively provided with an inner retaining ring 4 and an outer retaining ring 5, the outer periphery of the inner retaining ring 4 is provided with a raised clip strip 18, and the inner wall of the outer retaining ring 5 is provided with a concave bayonet 17. The clip strip 18 and the bayonet socket 17 can be snapped together. The inner bag 2 and the outer bag 1 are engaged with each other through the clip strip 18 and the bayonet opening 17 . The...

Abstract

The invention relates to a thread engagement type double-layer combined dedusting cloth bag. The cloth bag comprises an outer bag and an inner bag, wherein the outer bag comprises outer dedusting cloth, an outer frame and an outer retaining ring; the inner bag comprises inner dedusting cloth, an inner frame, an inner retaining ring, a vibrating motor, an electric dedusting grid, a pulse back flushing spray head, a bottom plate, and a motor hood, wherein the electric dedusting grid is arranged at the upper part of the inner bag, the pulse back flushing spray head is arranged in the center of the electric dedusting grid, the bottom plate of the inner bag is arranged on the bottom part of the inner bag, the vibrating motor is arranged on the bottom plate, and the inner bag and the outer bag are connected by using thread engagement. The head engagement type double-layer combined dedusting cloth bag adopts the combined filtering of the double-layer cloth bag and electric dedusting, has the extremely better filtering effect than that of existing dedusting cloth bags, and has the relatively high dedusting capacity due to the combination of pulse air flow and vibration.

Description

technical field [0001] The invention relates to the technical field of desulfurization, denitrification and dust removal, in particular to a spin-in type double-layer mixed dust removal cloth bag for flue gas and its manufacturing process. Background technique [0002] Most of the dust-removing cloth bags used today are composed of dust-removing cloth, dust-removing cover and skeleton. Blockage, resulting in greatly reduced dust removal effect. The upper part of the dust bag is easy to be damaged during the cleaning process of the high-pressure air flow, resulting in frequent replacement of the dust bag and increasing the cost. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a screw-in double-layer mixing dust bag. [0004] The present invention is achieved through the following technical solutions: [0005] The screw-in double-layer mixed dust bag is composed of an outer bag and an inn...
