High-temperature cyclone secondary deduster

Abstract

The invention relates to a high-temperature cyclone secondary deduster which comprises a cylinder body made of high-temperature-resistant materials. The opening end of the cylinder body is downward, an opening is arranged at the central position of the sealing end at the upper end of the cylinder body, a central cylinder is connected at the central position in sealing mode, and the lower end of the central cylinder extends into the cylinder body. A wall body in a cone cylinder shape is connected at the position below the opening end of the cylinder body, the diameter of the opening position at the upper end is identical to the internal diameter of the opening end of the cylinder body, the diameter of the opening position at the upper end of the wall body is larger than that of the opening position at the lower end of the wall body, and an ash collection cylinder is connected at the opening position at the lower end of the wall body. The wall body is formed by fire-resisting bricks in piling mode. The high-temperature cyclone secondary deduster is characterized in that a smoke inlet is respectively arranged at the radial opposite positions on the section of the lateral wall of the cylinder body corresponding to the central cylinder. The two smoke inlets of the secondary deduster can be simultaneously connected with two smoke outlets of a primary deduster so that flow speed of smoke entering an inner cavity of the secondary deduster is increased, fine harmful material particles in high-temperature smoke are further removed, and pollution to the environment caused by exhausted smoke can be effectively reduced.

Description

technical field [0001] The invention relates to a garbage incineration device, specifically a high-temperature cyclone secondary dust collector for cyclone dust removal of high-temperature flue gas after garbage incineration and first-stage dust removal. The flue gas outlet port is connected. Background technique [0002] At present, in the waste disposal industry, a large amount of domestic waste and industrial waste needs to be transported to waste recycling stations for recycling, and finally incinerated by waste incinerators. After the garbage is incinerated in the incinerator, a large amount of high-temperature flue gas will be produced, and this high-temperature flue gas contains a large number of harmful substance particles. Directly discharging this high-temperature flue gas into the atmosphere will cause serious pollution to the environment. Therefore, it is necessary to install a dust collector at the flue gas outlet of the garbage incinerator. The dust collector...
