Embodiment

[0020] like Figure 1-3 As shown, a gas-liquid separator used in petroleum refining includes: a broken flow plate 1, a riser pipe 2, a distributor 3, a support plate 4, a round hole 5, a clamping plate 6, and a slot 7.

[0021] The center of the top of the distributor 3 is provided with a round hole 5, and several spiral tooth gaps 7 are uniformly provided at the bottom of the distributor 3, and a coaxial air riser 8 is arranged in the distributor 3; the top of the air riser 8 is evenly A supporting plate 4 is arranged in the circumferential direction, and its lower part is connected with the clamping plate 6, and the number of the clamping plate 6 is three. A broken flow plate 1 with broken flow holes is arranged below the clamping plate 6 .

[0022] The support plate 4 can be U-shaped, and its top end is fixed on the round hole 5 of the blister 3 by screws, and its lower end is fixed on the top of the air riser 8 . like figure 1 and image 3 The supporting plate 4 shown ...

Abstract

The invention relates to a separator, and belongs to the field of petroleum refining equipment, and particularly relates to a gas-liquid separator for petroleum refining. The gas-liquid separator for petroleum refining comprises a distributor, a round hole is formed in the center of the top end of the distributor, a plurality of spiral tooth clearances are evenly formed in the bottom of the distributor, and an air rising pipe coaxial with the distributor is arranged in the distributor. Supporting plates are evenly and annularly arranged at the top of the air rising pipe, the lower portions of the supporting plates are connected with clamping plates, and flow breaking plates with flow breaking holes are arranged below the clamping plates. The gas-liquid separator is simple in structure and good in distribution effect, no center flow is generated, the radial peak value deviation is small, local overheat and coking of a catalyst bed layer caused by uneven distribution of mixed materials are avoided, and therefore the quality of reaction products is guaranteed.

Description

technical field [0001] The invention relates to a separator, which belongs to the field of petroleum refining equipment, in particular to a gas-liquid separator used in petroleum refining. Background technique [0002] At present, in the petrochemical industry, in order to improve the yield and product quality of light oil, it is often necessary to carry out catalytic hydrogenation (such as hydrocracking and hydrofinishing) on ​​the products obtained from crude oil fractions, and further refine them. In the container, the distribution performance of the fluid directly affects the uniformity of the contact time between the reactant and the catalyst, and affects the degree of wetting of the inner and outer surfaces of the catalyst by the liquid, and the uneven distribution of the fluid will form cross flow and short circuit, which will eventually affect the bed layer. The temperature of the catalyst bed causes local overheating and coking of the catalyst bed, which shortens th...
