Furniture factory industry introduction

Furniture refers to the human maintenance of normal life, engaged in production practices and social activities essential apparatus and facilities of the broad categories. Furniture also follow the footsteps of the times continue to develop and innovate, to today's wide range of categories, with different materials, complete varieties, different uses. Is the establishment of an important basis for working and living space. Furniture industry produces products such as: tables and chairs, wardrobes, beds, doors and so on.

Furniture factory pollution hazards

Nowadays, people on the aesthetics of furniture products is becoming more and more high, many furniture products need to be painted to beautify the colour to have more market. Then in the painting process there is the use of paint and solvent mixing process produces benzene, toluene, xylene, non-methane hydrocarbons and other volatile organic waste gas, this kind of component will cause great harm to the human body, long-term inhalation of this kind of waste gas will be irritating to people, because the paint contains formaldehyde, will cause great irritation to human skin and mucous membranes, will make the human eye to produce dryness, tears, blurred vision, etc. Symptoms, some people will also have a nasal nose. Symptoms, some people will also produce nasal mucous membrane oedema, throat discomfort, skin itching and other effects.

Furniture factory paint exhaust treatment programme overview

Furniture factory paint exhaust VOCs treatment technology, now in line with environmental emission requirements, and play a role in reducing costs and efficiency of the treatment technology, is the use of combustion method of treatment technology is more economical and energy-saving. It is recommended to use: wet jet washing (multi-pipe) + dry filter + wind reduction and thickening + catalytic combustion combination of governance, governance can meet the emission requirements of standards!

Furniture factory paint waste gas treatment process flow

Wet jet washing (multi-tube) + dry filtration + activated carbon adsorption and concentration + catalytic combustion process (integrated system) process treatment. Organic waste gas is collected through the pipeline, and enters the pretreatment wet jet tower to remove paint dew, acidity and particulate matter purification. After purification, the gas is introduced into the dry filter to remove particles and zeolite adsorption of hazardous substances, and the organic waste gas is then sent to the activated carbon adsorption bed device, and the VOCs components in the waste gas are absorbed by the zeolite and discharged into the atmosphere after reaching the standard. When the zeolite adsorption bed is saturated by electric heating at high temperature (80-100 ℃ C) desorption of VOCs substances, desorption of high concentrations of organic waste gas directly into the catalytic combustion co, through the accelerated oxidation of high concentrations of waste gas by precious metals, in ( 250-350 ℃) high temperature purification and oxidation of harmless carbon dioxide (CO2) and water vapour (H20) and standards discharged into the atmosphere.

Other treatment process technology

Low concentration of small air volume furniture factory paint exhaust can be used: spray tower, uv photolysis purifier, activated carbon adsorption and other single or multiple combinations of processes for treatment;

High concentration of small air volume furniture factory paint exhaust can be used: pretreatment + zeolite molecular sieve + catalytic combustion, pretreatment + zeolite molecular sieve + RTO thermal storage incinerator, a single catalytic combustion device or a single RTO thermal storage incinerator and so on;

High concentration and large air volume furniture factory paint exhaust can be used: pretreatment + zeolite rotor concentration + catalytic combustion or pretreatment + zeolite rotor concentration + RTO thermal storage incinerator and so on.
