Embodiment 1

[0021] see Figure 1~2 , in an embodiment of the present invention, a bag-type dedusting device for a thermal power plant includes a dust-removing box 1 and an ash hopper 2; ; The ash hopper 2 is connected to the bottom of the dust removal box 1, and the ash hopper 2 is provided with a dust outlet 21;

[0022] The top of the dust removal box 1 is provided with a movable cover 4, and the movable cover 4 covers the dust removal box 1 inside, and the top of the dust removal box 1 is provided with a perforation 12; the movable cover 4 is provided with an air outlet 41, and the movable cover 4 A plugging block 5 adapted to the perforation 12 is installed on the inner top surface of the inner top surface, so that when the plugging block 5 is disengaged from the air outlet 41, the gas in the dust removal box 1 enters the movable cover 4 through the perforation 12, and then Discharge from air outlet 41 again; On the outer wall of described movable cover 4, connecting plate 42 is fixe...

Embodiment 2

[0030] see image 3 , the embodiment of the present invention mainly improves the bag assembly to a certain extent, specifically:

[0031] The bag assembly 3 includes a bag main body 33, a bracket 31 for supporting the bag main body 33, and a cover plate 32 fastened with the bracket 31; A plurality of vertical rods 312 are fixed equidistantly along the circumferential direction; the cover plate 32 is connected to the base plate 311 through a magnetic attraction. The cover plate 32 is buckled on the base plate 311 by the magnetic attraction between them, thereby fixing the bag main body 33, and when the bag needs to be cleaned, the cover plate 32 only needs to be removed, and then the bag main body 33 can be taken off. , the operation is simple and quick.

[0032] To sum up, in this embodiment, by setting the bag assembly composed of the bag body 33 , the bracket 31 and the cover plate 32 , the bag body 33 can be easily disassembled, which provides great convenience for subse...

Abstract

The invention discloses a bag dust removal device for a thermal power plant, and relates to the field of power plant facilities. The device includes a dust removal box and a dust hopper; the side edgeof the dust removal box is provided with an air inlet, and bag assemblies are arranged in the dust removal box; the dust hopper is connected to the bottom of the dust removal box, and the dust hopperis provided with a dust outlet; a movable cover is arranged above the dust removal box, the movable cover covers the dust removal box, and the top of the dust removal box is provided with a through hole; the movable cover is provided with an air outlet, and the inner top surface of the movable cover is provided with a plugging block in fit with the through hole; and the outer wall of the movablecover is fixedly provided with connecting plates, and every connecting plate is connected and mounted to a connecting seat on the outer wall of the dust removal box by a connecting spring. The deviceis provided with the movable cover, and the connecting springs are used to connect the movable cover with the dust removal box, so resistance of the connecting springs needs to be overcome during theflow-out of air in the dust removal box, thereby the dust removal cycle of waste gas in the dust removal box is prolonged, and the dust removal effect is ensured.

Description

technical field [0001] The invention relates to the field of power plant facilities, in particular to a bag dust removal device for a thermal power plant. Background technique [0002] A power plant, also known as a power station, is a factory that converts various primary energy stored in nature into electrical energy (secondary energy). At the end of the 19th century, as the demand for electricity increased, people began to propose the idea of ​​establishing an electricity production center. With the development of motor manufacturing technology, the expansion of the application range of electric energy, and the rapid growth of the demand for electricity in production, power plants have emerged as the times require. There are many ways to generate power in current power plants: those that rely on thermal power are called thermal power plants, those that rely on hydroelectric power are called hydropower plants, and some power plants that rely on solar (photovoltaic) and wi...
