TECHNICAL FIELD
[0001] The utility model relates to a kind of oblique tee inlet pipe structures, specifically to a kind of industrial waste gas treatment equipment oblique tee inlet pipe structure, belong to waste gas treatment technical field. BACKGROUND
[0002] In the electronic industrial production field such as photovoltaic, semiconductor and panel, waste gas treatment is an important link of environmental protection. The rationality of the structure design of the oblique tee inlet pipe structure as an important component of the waste gas treatment equipment directly affects the maintenance efficiency of the waste gas treatment equipment.
[0003] The existing technology oblique tee inlet pipe structure design has certain irrationality, one of which is that disassembly is cumbersome. Specifically, the tee valve is usually fixed on the equipment. When maintenance and maintenance, or repair reaction chamber are needed, the oblique tee inlet pipe cannot be directly disassembled due to the center support, and the upper tee valve needs to be disassembled first, which consumes a lot of time and manpower, and brings inconvenience to the maintenance and maintenance of the equipment. On the other hand, the gas in the reaction chamber often flows backward into the inlet pipe, causing chemical reaction in the inlet pipe, and further causing scaling and heating, which affects the production stability.

[0004] The utility model provides a kind of industrial waste gas treatment equipment oblique tee inlet pipe structure, which aims to overcome the above-mentioned deficiencies of the prior art, simplify maintenance and ensure production stability
[0005] The technical solution of the utility model: a kind of industrial waste gas treatment equipment oblique tee inlet pipe structure, its structure includes the gas inlet variable diameter straight pipe, A straight pipe, gas inlet elbow and B straight pipe connected in sequence, wherein the gas inlet variable diameter straight pipe large diameter end connects A straight pipe, the gas inlet variable diameter straight pipe small diameter end connects the gas inlet oblique tee inclined end, the gas inlet oblique tee lower end port is connected to the reaction chamber of waste gas treatment equipment by lower outlet connection flange, and B straight pipe is connected to the three-way valve of inlet pipe by upper inlet connection flange. The above structure can simplify disassembly and maintenance, and avoid the reverse flow of gas in the reaction chamber.
[0006] Preferably, the lower outlet connection flange, the gas inlet oblique tee, the gas inlet variable diameter straight pipe, the A straight pipe, the gas inlet elbow, the B straight pipe and the upper inlet connection flange have a height-width ratio of greater than or equal to 0.8. This can further prevent the reverse flow of gas in the reaction chamber.
[0007] Preferably, the upper inlet connection flange and the lower outlet connection flange are KF type vacuum flanges. This can ensure stable connection.

DETAILED DESCRIPTION
[0012] The utility model will be further explained in detail in combination with examples and specific implementation manners.
[0013] As shown in Figure 1 , 2 , an industrial waste gas treatment equipment inclined tee inlet pipe structure, the structure includes the gas inlet variable diameter straight pipe 2, A straight pipe 4, gas inlet elbow 3 and B straight pipe 5 connected in turn, wherein the gas inlet variable diameter straight pipe 2 large diameter end connects A straight pipe 4, the gas inlet variable diameter straight pipe 2 small diameter end connects the gas inlet inclined tee 1 oblique end, the gas inlet inclined tee 1 lower end port is connected with the reaction cavity C of the waste gas treatment equipment through the lower outlet connecting flange 7, B straight pipe 5 is connected with the gas pipe tee valve D through the upper inlet connecting flange 6, the lower outlet connecting flange 7, the gas inlet inclined tee 1, the gas inlet variable diameter straight pipe 2, A straight pipe 4, gas inlet elbow 3, B straight pipe 5 and the upper inlet connecting flange 6 overall width-height ratio (A:B) is greater than or equal to 0.8.
[0014] The upper inlet connecting flange 6 and the lower outlet connecting flange 7 are preferably KF type vacuum flanges.
[0015] According to the above structure, the length of the multiple straight pipes makes the width-height ratio (A:B) of the entire inclined tee inlet pipe structure greater than or equal to 0.8. The waste gas is input from the gas pipe through the gas pipe tee valve D through the upper inlet connecting flange 6, the pipeline diameter gradually decreases, and then enters the reaction cavity C through the lower outlet connecting flange 7. The lower outlet connecting flange 7 and the reaction cavity C connection place can be preferably provided with a scraper. When the diameter is contracted, a section of high-speed pipeline can be formed to prevent the gas in the reaction cavity C from flowing upward, especially oxygen, because the sweeping gas is generally selected as nitrogen with a molecular weight of 28, and the molecular weight of oxygen is 32. Since the nitrogen molecules are lighter, a molecular barrier can be formed in this section to prevent oxygen from diffusing upward.
