1. Overview of furniture spraying exhaust gas

During the furniture spraying process, various coatings and solvents are used, and a large amount of organic waste gases such as benzene, toluene, xylene, formaldehyde, etc. are generated by volatilization during the spraying and drying process. These exhaust gases have irritating odors, and long-term inhalation can cause damage to the respiratory and nervous systems of the human body. In addition, they can also cause pollution to the atmospheric environment. Therefore, it is necessary to purify the exhaust gas from furniture spraying.

2. Furniture spraying exhaust gas treatment equipment

At present, there are various types of furniture spraying exhaust gas purification equipment commonly available in the market, including activated carbon adsorption boxes, activated carbon adsorption desorption CO catalytic combustion equipment, zeolite rotary adsorption concentration+RTO thermal storage incineration equipment, and zeolite rotary adsorption concentration+CO catalytic combustion equipment. Below, Tianhaoyang Environmental Protection Editor will provide a detailed introduction to furniture spraying exhaust gas treatment equipment.

2.1 Activated carbon adsorption box

Activated carbon adsorption box utilizes the porous structure and large specific surface area of activated carbon to adsorb organic substances in exhaust gas. When the exhaust gas passes through the activated carbon layer, the organic substances will be adsorbed in the pores of the activated carbon, thereby achieving the purpose of purifying the exhaust gas. This device is easy to operate, easy to maintain, and suitable for treating low concentration exhaust gases.

2.2 Activated carbon adsorption desorption CO catalytic combustion equipment

Activated carbon adsorption desorption catalytic combustion equipment is a waste gas treatment device that combines adsorption concentration unit and thermal oxidation unit organically. It is mainly suitable for organic waste gases with low to medium concentrations and not suitable for direct combustion or catalytic combustion and adsorption recovery methods, especially for high air volume treatment sites. After adsorption purification and desorption, the exhaust gas is converted into organic waste gas with low air volume and high concentration, which is subjected to thermal oxidation treatment and effectively utilizes the heat released by the combustion of organic matter.

Activated carbon adsorption desorption catalytic combustion equipment has high adsorption and purification efficiency, with a purification efficiency of up to 95%. It has stable operating performance, safety and reliability, low energy consumption, and no secondary pollution. It is controlled by PLC, easy to use and operate, simple maintenance and management, long service life, and renewable carrier. It is suitable for purifying and treating exhaust gas generated from continuous or intermittent production.

When choosing furniture spraying exhaust gas purification equipment, it is necessary to consider comprehensively based on the actual situation. Firstly, the composition and concentration of exhaust gas should be considered, as different types of equipment have different purification effects on exhaust gas with different compositions and concentrations. Secondly, the operating cost and maintenance difficulty of the equipment should be considered, and economical, practical, and easy to maintain equipment should be selected. In addition, factors such as equipment footprint and emission standards should also be considered.
