Problems solved by technology

The melting capacity of these zinc melting furnaces is low, and the labor load of the furnace workers is relatively large, especially the melting furnaces that use coal as fuel need to add coal manually, which not only requires workers to have certain experience, but also easily produces black smoke to pollute the environment

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1 to Figure 5 As shown, a smokeless zinc melting furnace combustion system of the present invention includes a furnace body 1, a feeding dump 2, a spiral slag wrapping device 36, an automatic feeding device 37, an air preheater 3, a dust collector 4, and an induced draft fan 5. Air blower 10, chimney 12, reciprocating push-feed grate 13, etc.

[0023] The body of furnace 1 is equipped with a reciprocating push-feeding fire grate 13, and a spiral slag revolving device 36 is installed below the slag outlet 6 ( Figure 5 ); 2 feeding openings of the feeding dump are provided with an automatic feeding device 37. The reciprocating push-feed grate 13 is used to replace the original fixed grate, the coal is fed by the tipping bucket, and the slag is discharged by the spiral slag wrapper 36, which greatly reduces the labor of the firema...

Abstract

The invention relates to a smokeless combustion system for a zinc melting furnace. The combustion system comprises a furnace body and a feeding skip bucket and is characterized in that a reciprocating push feed type fire grate is installed in the furnace body, a spiral slag entrapment device is installed below a slag outlet, and an automatic feeding device is arranged on a feeding port of the feeding skip bucket. The smokeless combustion system for the zinc melting furnace further comprises an air preheater and a deduster, a smoke outlet and an air inlet of the furnace body are connected with the air preheater respectively through a flue and a hot air duct, and the air preheater is connected with a chimney through the deduster and a draught fan. The automatic feeding device, the reciprocating fire grate and an automatic deslagging device are adopted in the smokeless combustion system for the zinc melting furnace, a vicious cycle period can be avoided, the combustion efficiency of the zinc melting furnace is improved, and the problem that black smoke is discharged out of the chimney is solved simultaneously.

Description

technical field [0001] The invention relates to a combustion system of a zinc melting furnace, in particular to a smokeless type zinc melting furnace combustion system. Background technique [0002] In China, the coal combustion system of many zinc melting furnaces has been using the traditional design method. Most of them use coal-fired hand-fired furnaces or coal-fired reverberatory furnaces. During the combustion process, the fuel needs to be added manually. Uniform, intermittent combustion of coal is insufficient, which will lead to the intermittent, intermittent and large instantaneous concentration of smoke and dust. This kind of combustion method is very easy to produce black smoke intermittently. This phenomenon not only seriously pollutes the environment and affects the atmosphere quality, which seriously affects the living environment of surrounding residents, and is a great waste of energy. [0003] In recent years, China's zinc metallurgical production has devel...
