Abstract

The novel washing tower provided by the invention adopts a washing and demisting integrated design, and has the advantages of small occupied area, high treatment efficiency, no blockage, no material consumption and the like.

Description

Novel water washing tower

Technical Field

A novel water washing tower belongs to a waste gas treatment washing tower, is widely applied to the pretreatment of industrial waste gas purification, dust removal and the like, has good purification effect, and is suitable for gaseous and liquid pollution sources.

Background

At present, the washing tower for purifying and dedusting the waste gas on the market has a simple treatment method, is commonly used as pretreatment equipment, and is widely applied to the treatment of various harmful gases such as H2S, NOX, NH3, CI2 and the like, and the treatment of waste gas discharged by garbage transfer stations, sewage plants, semiconductors, incinerators and industrial furnaces.

In the waste gas treatment process, a series of other equipment is often matched behind a washing tower for waste gas treatment, such as a photocatalytic oxidation tower, a high-voltage electrostatic adsorption tower, an activated carbon adsorption tower and the like, so as to reach the national minimum emission standard or be far lower than the emission standard.

In order to ensure the normal and efficient operation of the following treatment equipment, the water scrubber used as the pretreatment is generally used as a demisting device to prevent liquid films (water drops) sprayed by the spray heads contacting with the waste gas or the waste gas from being brought into the following treatment equipment under the action of the wind pressure of the fan to influence the treatment efficiency.

The structure of the defogging device in the market at present is roughly divided into a cyclone plate defogging device, a filler defogging device, a coconut shell palm fiber net defogging device, a wire mesh defogging device and the like, many of the devices are used in a composite mode, a defogging layer and a washing tower are generally made into a whole, a defogging tower is also made behind the defogging tower, the defogging efficiency of the washing tower adopting the cyclone plate or the filler as a defogging medium is extremely low, and the filler is easy to block, so that the air volume for treatment is influenced; the wire mesh defogging and coconut shell palm net defogging efficiency are higher than the former, but the shortcoming is that the windage is big, has increased the energy consumption, easily causes the jam, especially handles in the waste gas treatment that contains oil or dust volume is big (trade such as spraying paint, printing ink), and the jam is comparatively serious, and life cycle is short, uses the maintenance cost height.

Drawings

FIG. 1 is an oblique view of the appearance of the new water scrubber.

FIG. 2 is a structural view (including an internal structural view) of the novel water washing tower.

Detailed description of the preferred embodiments

A novel washing tower structure comprises a shell 1, a water tank 2, a water pump 3, a spraying structure 4, a middle connecting pipe 5, a demisting device 6 and a viewing window 7, wherein the internal structure comprises a filler supporting plate 8, an air outlet 9, a spraying pipe 10, an air outlet 11, a water outlet 12 and connecting reducing holes 13, which are shown in figure 2; PP packing is filled between the packing supporting part 8 and the spray pipe 10, the figure is a two-layer spray type, and two layers of packing are required to be added.

The operation state of the novel washing tower is that the bottom of a shell 1 is communicated with a water tank 2, acid, alkali, hydrogen peroxide or other agents and water are added according to different processing gases to be mixed into absorption liquid according to a proportion, the absorption liquid passes through a spraying structure 4 and a spraying pipe 10 by a water pump 3 and is sprayed into water mist by a spiral nozzle, a liquid film is formed by filling, and waste gas to be processed introduced into the washing tower by a fan is fully combined and decomposed, so that the effect of waste gas processing is achieved.

Claims

1. A novel water washing tower comprises a spraying part and a cyclone demisting part.

2. The spraying part is provided with two or three spraying pipe layers according to the actual treatment requirement, and the bottom water discharge pipe of the cyclone demisting extends to the position below the water level of the tower body.
