Technical Field

The utility model relates to a tail gas treatment facility technical field, in particular to a cooling dust removal structure for dry-type tail gas treatment facility.

Background

In the production and manufacturing process of factories in the industries of semiconductors, solar energy, liquid crystal panels, LEDs and the like, various electronic gases are used, and most of the gases are toxic and harmful hazardous gases, and may have corrosivity, flammability, explosiveness and the like. Some of these toxic and harmful gases are utilized in the production process, and some residual gases are discharged after treatment. Since the discharged gas is also a high-risk gas, it needs to be disposed of in time in a place near the main process equipment in the workshop to minimize the safety risk. At present, common gas treatment equipment is divided into a dry adsorption type, a water washing type, an electric heating water washing type, a plasma water washing type and the like, and particularly, in recent years, with the upgrading of processes in the manufacture of chips and solar cells, the application of plasma type tail gas treatment equipment is more and more popular.

The dry adsorption equipment is generally used for heating and decomposing the tail gas, and then absorbing the decomposed specific components through the adsorption tower, so that the treated gas reaches the emission standard. Since the heating causes the decomposed gas to contain high heat, water cooling is performed before the adsorption, and dust particles in the decomposed gas are easily entrained by the airflow to enter the adsorption tower in the process, so that the adsorption tower has a blockage risk. Chinese patent CN202598539U uses a water-cooled cyclone dust collector for separation, but this type of cyclone dust collector has a large volume and a large noise, and is not suitable for small dry tail gas treatment equipment.

Therefore, it is necessary to provide a new cooling and dust removing structure to solve the above problems.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1, the utility model discloses a cooling dust removal structure for dry-type tail gas treatment equipment, including water-cooling heat transfer portion 1 and the dust clearance chamber 2 that is located water-cooling heat transfer portion 1 below, dust clearance chamber 2 has the deashing mouth 21 that can open, be equipped with gas outlet 22 on the lateral wall in dust clearance chamber 2, the inboard of gas outlet 22 is equipped with baffle subassembly 3, baffle subassembly 3 includes towards the inboard lower baffle 31 of gas outlet 22 and the last baffle 32 that is located baffle 31 top down, last baffle 32 has a vertical face 321 that bends down to being less than lower baffle 31 topside, lower baffle 31 is located between vertical face 321 and the gas outlet 22, thereby form the passageway of a reciprocal turn between dust clearance chamber 2 and gas outlet 22. Gas generated by heating decomposition enters the cooling and dedusting structure from the upper part of the water-cooling heat exchange part 1, then the cooled gas enters the dust cleaning cavity 2, and then is discharged from the gas outlet 22 to the absorption tower. Before the air leaves the air outlet 22, the air flow passes through the channel formed by the baffle plate component 3, the descending air flow is turned for the first time on the bottom surface of the dust cleaning cavity 2, and after bypassing the vertical surface 321, the descending air flow is turned for the second time above the lower baffle plate 31, so that larger air flow resistance is generated, the air flow is decelerated, dust particles contained in the air flow drop into the dust cleaning cavity 2, and the air flow cannot be wrapped by the air flow to block the absorption tower. After dust in the dust cleaning cavity 2 is accumulated for a period of time, the dust can be cleaned out from the dust cleaning opening 21. The utility model discloses compact structure can not produce very big noise during collection dirt.

As shown in fig. 1, a lower reinforcement plate 311 is connected between the lower baffle 31 and the bottom surface of the dust cleaning chamber 2. An upper reinforcing plate 322 is provided inside the corner of the upper baffle 32. When the airflow passes through the channel between the upper baffle plate 32 and the lower baffle plate 31 in a turning manner, pressure is generated on the outer side surface of the opposite surface 321 and the outer side surface of the lower baffle plate 31, the two baffle plates can be deformed after working for a long time in the environment, so that the channel resistance is changed, the upper baffle plate 32 and the lower baffle plate 31 are not easily deformed by the aid of the upper reinforcing plate 322 and the lower reinforcing plate 311, and the stability of the airflow is kept.
