Environment-friendly flue gas purification device for waste incineration

Abstract

The invention discloses an environment-friendly flue gas purification device for waste incineration. The device comprises a heat exchange box, a motor and a spraying assembly. A mounting strip is fixed at the outer side of the heat exchange box, the motor is arranged at the end part of the mounting strip, and the output end of the motor is connected with a screw rod; the screw shaft is connected in a movable groove, the movable groove is formed in the mounting strip, and a movable block is in threaded connection with the outer side of the screw rod; a movable rod is fixed to one side of the movable block, penetrates through the inner wall of the heat exchange box and is located in the heat exchange box, a positioning block is installed at the outer side of a filter screen and is located ina positioning groove, the positioning groove is formed at the end of the guide pip, and the spraying assembly is installed at the top of a spraying box. According to the environment-friendly flue gaspurification device for waste incineration, the flue gas is purified through filtering and spraying, meanwhile, a waste heat recovery function is achieved, the impurities on a water pipe can be conveniently removed, and the filter screen can be conveniently detached 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...
