Technical Field
The invention relates to a gas/liquid distributor in the technical fields of petroleum refining, petrochemical industry, coal chemical industry and the like, in particular to a circular pipe detachable two-stage distributor capable of distributing gas or liquid.
Background
In industry, it is often necessary to redistribute feed gas/liquid within the vessel, and whether the gas/liquid distribution is uniform or not will directly affect the stability of the operation of the apparatus, and the gas/liquid distributor is an important component for the uniform distribution of feed.
The gas distributors in the prior art are mainly divided into two types, namely a tubular gas distributor and a plate gas distributor, and the tubular gas distributor is divided into an annular tubular gas distributor and a branch-shaped tubular gas distributor. Tubular gas distributors have the following advantages over plate gas distributors: the pressure drop is small, the deformation is not easy to occur, the weight is light, the internal structure of the device can be simplified, the height of the device can be reduced, and the abrasion to the catalyst is small, so that more tubular gas distributors are adopted at present.
Liquid distributors in the prior art are mainly divided into tubular liquid distributors, trough-tray type liquid distributors, liquid inlet pipes + split-flow trough type liquid distributors, and the like, and the tubular liquid distributors are divided into annular tubular liquid distributors and branch-type tubular liquid distributors. Tubular liquid distributors are used more because of many advantages.
The gas distributor disclosed in CN201720434473.1 adopts a branch type pipe, the branch pipes are installed in the equipment in parallel, the gas branch pipe is provided with at least one gas discharge hole, the middle part of the branch pipe is provided with a fixed block, and a support rod inside the equipment penetrates through the fixed block for fixation. CN201420306541.2 discloses a gas distributor which adopts a ring tube type, the distributor is composed of a distributor path A and a distributor path B, the distributor path A and the distributor path B are symmetrically arranged with the same structure, and the distributor path A and the distributor path B form a ring tube. The inner ring of the ring pipe is provided with a plurality of centripetal branch pipes, and the ring pipe and the branch pipes are uniformly provided with a plurality of air outlet holes. The novel gas distributor disclosed in CN201720370668.4 adopts a branch pipe + ring pipe structure, and is composed of a gas inlet pipe, a redistribution pipe, an annular distribution pipe, a gas injection pipe and an equipment casing which are connected in sequence. The gas outside the equipment enters the gas distributor through the gas distributor gas inlet pipe, then flows into the channels distributed by the gas redistribution pipe and the annular distribution pipe, and flows out through the gas injection pipes distributed at the lower end of the channels. CN201620942080.7 discloses a novel liquid distributor adopts the branch type tubular, and four main female pipes of cloth are established separately to central water inlet, four main female pipes evenly distributed of cloth, divide in every main female pipe of cloth and establish the cloth branch pipe, and each cloth branch pipe divide into eight branch road petal formulas and arranges, is equipped with three splash formula external screw thread shower nozzles on every cloth branch pipe, and the shower nozzle is evenly arranged. The liquid distributor disclosed by CN201710325503.X adopts a branch pipe + multilateral ring pipe structure, one end of a feeding main pipe is connected with the top of a liquid distribution cavity, the side surface of the liquid distribution cavity is communicated with radial distribution pipes, any two adjacent distribution pipes are communicated through the distribution branch pipes, a plurality of uniformly-arranged distribution pipe spraying holes are axially arranged on the pipe wall of each distribution pipe, and a plurality of uniformly-arranged distribution pipe spraying holes are axially arranged on the pipe wall of each distribution branch pipe.
The existing branch type tubular distributor and the existing annular tubular distributor have certain defects. The disadvantages of the branch type tubular distributor are: firstly, because the branch pipe flow passage is longer, the pressure distribution from the inlet to the tail end of the branch pipe is uneven; secondly, when a redistribution pipe + annular distribution pipe structure or a multi-branch distribution structure is adopted, the flowing directions of the fluid are inconsistent, and the fluid is disordered to influence the performance of the fluid; the main pipe and the branch pipe have different specifications, and the support beam is provided with an adjusting cushion block; fourthly, when the fluid is viscous, the outlet is blocked and is not easy to clean or replace. The disadvantages of the ring-type tubular distributor are: firstly, the pressure in the traditional annular tubular distributor is unevenly distributed because of only 1 inlet; secondly, the gas/liquid to be distributed is not uniformly distributed on the whole cross section of the container; thirdly, when the fluid is viscous, the outlet hole is blocked and is not easy to clean or replace.
