Example Embodiment

[0023] The technical solutions of the present invention will be described below with reference to the accompanying drawings, which is apparent from the accompanying drawings. Based on the embodiments in the present invention, those skilled in the art will belong to the scope of the present invention without making creative labor premistence.

[0024] Such as Figure 1 to 8 Indicated.

[0025] In this embodiment, a filter bag for a high temperature environment comprising a plurality of filter bags 3 in an annular array, and a plurality of filter bags 3 are combined together, and a number of departures on the turntable 1 for The mounting hole 2 of the filter bag 3 is attached to the top of the filter bag 3, and the height dimension of the threaded barrel 4 is larger than the height size of the mounting hole 2, and the threaded barrel 4 is filled with filtration. The inner cavity of the bag 3 is in contact with the bottom surface of the turntable 1, which is inserted with a rotary rin...

Abstract

The invention provides a filter bag for a high-temperature environment, which comprises a plurality of filter bags in an annular array, a turntable for combining the plurality of filter bags together, a plurality of mounting holes formed in the turntable and used for mounting the filter bags, and threaded cylinders arranged at the tops of the filter bags and matched in the mounting holes, the height of the threaded cylinder is larger than that of the mounting hole, the threaded cylinder is a flexible pipe communicated with an inner cavity of the filter bag, and a rotating ring capable of synchronously rotating along with the rotating ring is embedded in the bottom face of the rotating disc, so that when the filter bag is close to the air inlet, the distance between the filter bag and the air inlet is increased, and waste gas can be filtered while it is ensured that waste gas is filtered. The hot air is filtered only when the hot air is close to the filter bag from a long distance in a high-heat area far away from the hot air, so that the damage caused by heating influence can be reduced by combining the two modes of simultaneous action, and compared with the mode of only enabling the filter bag to quickly pass through the air inlet in the prior art, the protection of the filter bag is stronger.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a filter bag used in a high-temperature environment. Background technique [0002] The filter bag is installed in the dust removal equipment through the bag cage. The waste gas produced in the industrial production process is discharged from the waste gas pipe to the dust removal equipment through the filter bag, and the dust is intercepted by the filter bag to purify the waste gas. [0003] The exhaust gas produced in the production environment of thermal power plants has a certain amount of heat. When it is directly passed into the dust removal equipment and processed by the filter bag, it is very likely to cause the filter bag to melt. In order to solve this problem, the Chinese patent application number CN201822219103.3 has disclosed A high-temperature-resistant filter bag dust removal device, including a main body of a filter bag dust collector, a top cover ...
