Waste gas purification tower

Abstract

The invention discloses a waste gas purification tower. The waste gas purification tower comprises a first tower body, wherein the top of the first tower body is provided with a first exhaust port; a first inner tower tube is sleeved inside the first tower body; the bottom of the first inner tower tube is close to the bottom of the first tower body; a first inner air chamber and a first outer air chamber are respectively arranged inside and outside the first inner tower tube; a first air inlet communicated with the first inner air chamber is formed in the side wall, close to the top end, of the first tower body; foam spray heads are distributed inside the first outer air chamber. The waste gas purification tower has the advantages of being simple in structure, high in purification rate, low in cost, free of cleaning and maintenance and the like, and can be widely applied to providing an excellent way for promoting the quality of social environment in industry, commercial business and life.

Description

technical field [0001] The invention relates to waste gas treatment technology, in particular to a waste gas purification tower. Background technique [0002] At present, exhaust gas treatment is widely used in various industrial places. There are many existing exhaust gas treatment methods, such as activated carbon adsorption, biological filter, plasma, catalytic oxidation, etc., all of which have a certain effect on exhaust gas purification. However, the treatment and purification effect is not good, and most of them still have problems such as complex equipment, high treatment cost, low purification rate, and high maintenance cost. [0003] Regarding the adsorption method, some people currently use foam adsorption to treat exhaust gas. For example, see the patent application (application number 201310118282.0) for a foam scrubber, which uses foam to treat exhaust gas. The specific treatment method is that a foam layer ( Specifically, the sieve plate mechanism), the waste...

Problems solved by technology

However, the effect of exhaust gas purification treatment is not good. One of the main reasons is that the exhaust gas is sent from the bottom of the tower under high pressure, and the exhaust gas rises directly and rapidly along the wind flow. In addition, the foam liquid cannot achieve a full tank, resulting in the contact time between the exhaust gas and the foam. Extremely short, most of the time the exhaust gas is sent to the top of the foam layer and discharged before it fully contacts with the foam

At present, a solution is to use two sets of foam adsorption devices. The gas outlet of the first set of foam scrubbers is connected to the gas input port of the second set of foam scrubbers. Although it can improve a certain exhaust gas purification rate, the effect is not good. significantly

At present, another solution is to further design the structure inside the tower. For example, in the patent application 201310118282.0, the foam layer (also the sieve plate mechanism) is provided with multiple layers, and a baffle is also provided under each layer. In practical application, The complex structural design not only reduces the effective space for the contact between the exhaust gas and the foam, not only does not prolong the contact time between the exhaust gas and the foam, but also causes a certain blockage to the circulation of the exhaust gas and affects the normal operation of the device. In addition, it also brings load to the cleaning and maintenance of the equipment burden
