Environment-friendly flue gas purification device for garbage incineration

Abstract

The invention discloses an environment-friendly flue gas purification device for garbage incineration. The environment-friendly flue gas purification device comprises a heat exchange box, a motor anda spraying assembly, wherein a mounting strip is fixed on the outer side of the heat exchange box; the motor is arranged at the end part of the mounting strip; the output end of the motor is connectedwith a screw rod which is in shaft connection with the interior of a movable groove; the movable groove is arranged in the mounting strip; the outer side of the screw rod is in threaded connection with a movable block; a movable rod is fixed on one side of the movable block; the movable rod penetrates through the inner wall of the heat exchange box and is positioned in the heat exchange box; positioning blocks are installed on the outer side of a filter screen and positioned in positioning grooves; the positioning grooves are formed in the end parts of guide pipes; and the spraying assembly is installed on the top of a spraying box. According to the environment-friendly flue gas purification device for garbage incineration, flue gas is purified through filtering and spraying, meanwhile, the waste heat recovery function is achieved, impurities on water pipes can be conveniently removed, and the filter screen can be conveniently disassembled and cleaned.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to an environment-friendly flue gas purification device for garbage incineration. Background technique [0002] Garbage in life and industry is usually treated by incineration. During the process of garbage incineration, a large amount of flue gas will be produced. There are many harmful impurities in the flue gas. In order to protect the environment, the flue gas after incineration usually needs to go through Purification treatment can be carried out, and a flue gas purification device is required. However, the existing flue gas purification device has the following problems: [0003] In the flue gas after incineration, the temperature is high, and the flue gas purification device will involve the recovery of waste heat in the process of purifying the flue gas. When the existing flue gas purification device recovers the waste heat, the water pipe Impurities will accu...
