Device for filtering naked flame particles in mixed flue gas

Abstract

The invention provides a device for filtering naked flame particles in mixed flue gas, which comprises a bracket, an air outlet, a check ring, an insulating layer, a screen drum, a box body, an air inlet, an upper cover and a transmission device. The surface of the screen drum is covered with a strip metal wire net. Metal wires in the strip metal wire net have cone sections so as to effectively stop naked flame particles in the flue gas. The upper part of the screen drum is connected with the transmission device, while the lower part extends into the check ring. The insulating layer is covered on the outer surfaces of the box body and the air outlet to form an insulation structure of the device for filtering the naked flame particles in the mixed flue gas. The device can effectively remove naked flame from the high temperature or mixed flue gas, prevent detonation of combustible materials, keep temperature of the flue gas and reduce heat loss.

Description

technical field [0001] The invention belongs to the field of filtering and fire prevention, and in particular relates to a device for filtering spark particles in mixed smoke. Background technique [0002] At present, various raw coals mined in my country's coal mines have high water content due to various reasons, such as mining methods, underground water seepage, spray water and other factors, so that the mined coal must be dried, that is, using high or low temperature. The flue gas heats the raw coal, which dehydrates and dries the raw coal. In the prior art, the method of burning coal to produce mixed flue gas is generally used to produce mixed flue gas, but the mixed flue gas produced by this method inevitably contains sparks, and such sparks inevitably cause the drying process. Part of the raw coal is burned, which not only wastes the raw coal, but also reduces the quality of the dried coal. [0003] In order to improve the quality of the flue gas, the inventor search...

Problems solved by technology

[0004] In addition, because the flue gas dust removal device in the prior art cannot selectively filter out the smoke and flowable particles in the flue gas, and the smoke itself is the agglomeration of tiny particles, the flue gas dust removal device in the prior art filters a large amount of dust in the flue gas. Smoke and flowable particles, so that the temperature of the flue gas after the treatment of the flue gas dust removal device in the prior art is reduced sharply; Not suitable for supplying flue gas in raw coal drying
