Problems solved by technology

[0015] For the three technologies of combustion, their treatment rate of waste gas can reach more than 95%, but direct combustion wastes a lot of heat energy and is prone to explosion; catalytic combustion has high requirements for the gas itself, and is prone to catalyst poisoning ; Although thermal combustion can recover part of the heat energy, the operating cost is too high

Embodiment Construction

[0040] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0041] The invention provides a method and device for purifying high-temperature oil-containing waste gas of a heat-setting machine. The simulated oily fume waste gas device 1 generates high-temperature oil-containing waste gas from a simulated heat-setting machine at a temperature of 150-170°C. The high-temperature oil-containing waste gas of the simulated heat setting machine passes through the gas-water heat pipe high-efficiency heat exchange device 2 to reduce the temperature of the waste gas to below 60 degrees, recover the heat energy in the waste gas and condense some components in the waste gas; then enter the new deoiling process Dust removal equipment 3 removes large solid particles and condensed liquid oil particles in the exhaust gas; finally, finely filters through the ramie filter 4 equipped with ramie fiber tubes to furt...

Abstract

The invention provides a purifying method and set of high-temperature oil-bearing waste gas for a heat-setting machine. The heat in the high-temperature oil-bearing waste gas is recovered by a gas-water heat-tube efficient heat exchanger, part of components in the gas are condensed; large solid particles and condensed liquid oil particles in the gas are removed by a novel deoiling dedusting device; a ramie filter loaded with ramie fiber tubes is used for fine filtering so as to further remove fine particles from the gas. The purifying method and set allows the high-temperature oil-bearing waste gas from the heat-setting machine to be effectively purified and has the advantages such that the process is simple, purifying efficiency is high, energy consumption is reduced and operation cost is low.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment in the textile industry, in particular to a method and device for purifying high-temperature oily waste gas from a heat setting machine. Background technique [0002] The high-temperature oily exhaust gas of the heat setting machine is a kind of exhaust gas generated when the dyeing and finishing machine sets the cloth. The working temperature of the heat setting machine is generally around 200°C, and the temperature of the exhaust gas leaving the heat setting machine is generally around 170°C. The exhaust gas of the heat setting machine not only contains a large amount of fibers and dust, but also contains polyphenylene organic matter, printing and dyeing auxiliaries, etc. Harmful ingredients. The generated fine dust and oil stains are easy to adhere to the inside of the device or accessories. When the exhaust gas is transferred and moved between the discharge port of the setting mac...
