A lead-containing waste gas treatment device produced by lead quenching in steel wire production

Abstract

The invention discloses a device for treating lead-containing waste gas produced by lead quenching in steel wire production. The device comprises a housing, a washing chamber, a heating chamber, a combustion chamber, a heater and a pretreatment device, wherein the washing chamber, the heating chamber and the combustion chamber are positioned in the housing; the heater is positioned in the heatingchamber and is used for heating waste gas; and the pretreatment device is positioned at one end of the housing and is used for primarily treating the waste gas. According to the device, two clamping plates are arranged; the mounting positions of heating plates and clamping plates are adjusted during the mounting of the heating plates, thus the interval between every two of a plurality of heating plates can be adjusted, and the temperature covering range of the plurality of heating plates in heating and the increasing temperature of surrounding temperature of the plurality of heating plates canbe changed, and as a result, the heating speed of the space in the heating chamber can be adjusted as requirement; the temperature covering range and speed of a heater in the heating chamber can be adjusted based on the air inlet volume and the air inlet speed, thus the waste gas can be timely fully heated; and the combustion speed is increased while the waste gas enters the combustion chamber, and as a result, the waste gas treatment efficiency can be improved.

Description

technical field [0001] The invention relates to the structural field of a lead-containing waste gas treatment device, specifically a lead-containing waste gas treatment device produced by lead quenching in steel wire production, and belongs to the application technical field of lead-containing waste gas treatment devices produced by lead quenching. Background technique [0002] The high specific heat capacity and low melting point of lead make it widely used in the field of heat treatment. The fine pearlite steel wire produced by this heat treatment technology of lead quenching is conducive to drawing processing, and makes the finished steel wire have better strength and toughness. [0003] The existing lead waste gas treatment methods mainly include dry method and wet method, among which the lead waste gas treatment device using wet method has a relatively complicated structure, and needs to occupy a large amount of use space, and requires multiple operations during use, and...

Problems solved by technology

[0004] The object of the present invention is to provide a lead-containing waste gas treatment device produced by lead quenching in steel wire production, to solve the problem of using wet treatment of lead waste gas treatment device, its structure is mostly complicated, and needs to occupy a large amount of use space; Multiple operations, and when the existing wet lead waste gas treatment device uses water washing, the heating treatment after water washing cannot be adjusted in time according to the needs and adjust the heating temperature in the heating chamber in time; and the existing wet lead waste gas treatment device is washing, heating Before the treatment, there is no pretreatment of the lead waste gas, which makes the whole lead waste gas treatment take a long time and the treatment effect is low.
