Problems solved by technology

At present, there are many ways to control VOCs pollution. Activated carbon adsorption VOCs method, vacuum negative pressure method, ammonia gas absorption method, etc. are relatively common methods, but these methods also have some corresponding shortcomings, such as secondary pollution treatment of ammonia gas, etc.

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 A new type of VOCs removal device for building panels is shown, which is mainly composed of a DC high-voltage power supply 1, an electrode plate 2, a VOCs treatment room 4 and a fan 5. The top side of the VOCs treatment room is provided with an air inlet 6, and the bottom is provided with a Exhaust port 7.

[0020] Put the building board sample from the feed port on the side of the VOCs treatment chamber, fix it through the bracket on the wall, and place it between the two electrode plates. Turn on the DC high-voltage power supply to generate a stable high-voltage electrostatic field between the electrode plates, thereby accelerating and improving the volatilization of VOCs in the plates. At the same time, through the air supply port on the top side of the VOCs treatment room, ordinary air is sent into the treatment room, and then bl...

Abstract

The invention discloses a novel removal device for VOCs in building boards. The removal device comprises a direct-current high-voltage power source, plate electrodes, a VOCs treatment chamber and a fan. The plate electrodes are a pair of electrodes in parallel and are arranged inside the VOCs treatment chamber, the fan is fixed to the top end inside the VOCs treatment chamber, and an air inlet is further formed in the top of the VOCs treatment chamber. An exhaust port is formed in the bottom of the VOCs treatment chamber, a feeding port is formed in the side face of the VOCs treatment chamber and directly faces the part between the pair of electrodes in parallel, the direct-current high-voltage power source generates a stable electric field, voltage strength is 40 kV / m-80 kV / m, and the two electrodes of the direct-current high-voltage power source are connected with the pair of electrodes respectively. Through increasing the quantity of released VOCs in the boards, the quantity of residual VOCs in the boards is smaller, and the boards are environmentally friendlier and safer. The novel removal device has the advantages of being simple in structure, low in cost, convenient to operate, high in efficiency and the like.

Description

technical field [0001] The invention relates to a treatment device for reducing or removing the content of VOCs (Volatile Organic Compounds: volatile organic compounds) in the board during the production process of various boards. Background technique [0002] The U.S. Environmental Protection Agency pointed out that porous building materials have been identified as an important source of indoor air pollutant emissions. Indoor air quality problems caused by the volatilization of VOCs in building materials may lead to various diseases, such as headaches; eye, nose or throat irritation; Dry cough; dizziness and nausea; difficulty concentrating and tiredness. [0003] The main sources of VOCs are interior decoration materials and furniture, especially wood-based panels. These synthetic woods such as medium density boards and particle boards contain a large amount of VOCs and other toxic substances that are difficult to volatilize quickly at room temperature. In daily life, the...
