Problems solved by technology

However, there are many types of waste gas, and industrial waste gas also contains certain dust. The above-mentioned patents do not disclose the pre-treatment and post-treatment of industrial waste gas in detail.
However, if you want to choose the method of ultraviolet photolysis, the pre-treatment must remove dust and water-soluble organic matter, and the post-treatment must recover the organic and inorganic waste gas products after cracking.

Embodiment 1

[0047] Treatment of organic waste gas from pesticide factories. The content of acetic acid and methyl ester in exhaust gas is 300-500mg / m 3 .

[0048] Device parameters: Dimensions: 1200×600×2200mm (length×width×height); motor power: 5.5Kw; total air volume: 4500cmh, wind speed: 18m / s;

[0049] The result after treatment is that the content of acetic acid and methyl ester in the exhaust gas is 2-5mg / m 3 , The odor removal rate is over 90-95%.

Embodiment 2

[0051] Removal of lipid waste gas in kitchen fume exhaust system. National emission standard is 2000mg / m 3 , the measurement result of this device is 0.18mg / m 3 .

Embodiment 3

[0053] Treatment of waste gas from benzene ring and its derivatives in chemical plants.

[0054] Device parameters: Dimensions: 2500×2200×2500mm (length×width×height); motor power: 15Kw; total air volume: 36000cmh, wind speed: 25m / s;

[0055] As a result of the treatment, the scavenging rate of the benzene ring and its derivatives was greater than 70%.

[0056] The invention has the characteristics of simple operation, convenient maintenance and integrated structure, greatly reduces the production cost, and realizes the thorough purification of toxic and harmful gases.

Abstract

The invention discloses a waste gas treatment air purification device which comprises a unit case, a waste gas inlet pipe, and an air inlet pipe; the invention is characterized in that a water tank is disposed at the bottom inside the unit case; a photolytic light source, a filler layer, a spraying layer, and an active carbon layer are orderly mounted above the water tank; the waste gas inlet pipe and the air inlet pipe extend into the water tank at one side of the unit case. With a water-attack deduster principle, the invention allows organic waste gas to dissolve into water through high-speed air flow, performs cracking by using high-energy high-ozone ultraviolet light beams, performs air purification with the synergic photolysis of the fillers and spraying, and finally reaches the national discharge standard; the invention is simple in operation, convenient for maintenance, and integrated in structure, greatly reduces production cost, and realizes thorough purification of toxic and harmful gas.

Description

technical field [0001] The invention relates to an air purification device, in particular to an air purification device for waste gas treatment. Background technique [0002] Toxic and harmful exhaust gas pollution to the environment and stench nuisance are two issues that chemical enterprises must pay attention to. While chemical companies contribute to local GDP, they also bring troubles to surrounding residents. It can be said that the indescribable smell is the deepest memory of many people about the chemical plant. Some companies have also tried many methods, but the effect is not satisfactory. [0003] Due to the complex chemical reactions in the production process of chemical enterprises, the components of the waste gas are also very complex, which increases the difficulty of treatment. Some companies use activated carbon for adsorption. Due to the large amount of gas generated, the activated carbon will be saturated in two or three days; some companies use water w...
