Abstract
The utility model provides a novel gas distributor of an acetylene chlorination tower, comprising a main distribution pipe, both ends of the main distribution pipe are transversely communicated with short branched distribution pipes, the middle is transversely communicated with a long branched distribution pipe; medium branched distribution pipes transversely communicated with the main distribution pipe are positioned between the short branched distribution pipes and the long branched distribution pipe; rows of gas outlet holes are respectively positioned in the vertical direction of the lower half circumference of the wall of the main distribution pipe and both sides of the vertical direction; and a plurality of rows of branched distribution pipe gas outlet holes are distributed on the lower half circumferences of the walls of the branched distribution pipes. The novel gas distributor can enable a chlorine gas and an acetylene gas to be uniformly distributed, thereby effectively enhancing the product yield of the acetylene chlorination tower; crude tetrachloroethane has high purity, therefore the raw material unit consumption of trichloroethylene is further reduced; and in addition, the utility model prevents from the explosion of the acetylene chlorination tower, thereby ensuring safe production.
Description
Technical field
The utility model provides a kind of gas distributor, especially a kind of gas distributor that is used for acetylene chlorination tower.
Background technology
The domestic production enterprise overwhelming majority adopts gas phase catalysis dehydrochlorination method to produce trichloro-ethylene.Its production procedure is: chlorine, acetylene generate thick tetrachloroethanes in the chlorination tower, and thick tetrachloroethanes is vaporized after rectifying, and dehydrochlorination generates trichloro-ethylene in the dehydrochlorination reaction device, then through rectifying, produces qualified trichloro-ethylene product.The process that generates thick tetrachloroethanes is finished in acetylene chlorination tower.Say to a certain extent whether chlorine, the distribution of acetylene in the chlorination tower have rationally determined to generate the yield of thick tetrachloroethanes reaction.It is even more to distribute, and then the chlorination reaction yield is high more, and the purity of tetrachloroethanes is also high more, also just can further reduce the unit consumption of trichloro-ethylene.But at present, domestic production producer can cause acetylene, chlorine skewness because of the gas distributor unreasonable structure, can be when serious because of acetylene contact with chlorine, and the phenomenon of blasting, serious threat safety in production.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of acetylene chlorination tower new gas distributor, to improve the uniformity of distribution of gas.
The utility model is to realize like this, acetylene chlorination tower new gas distributor, it has main distributor pipe, main distributor pipe two ends are horizontally connected with a short distributor pipe, the middle part is horizontally connected with the distributor pipe of drawing money on credit, short distributor pipe, draw money on credit have between the distributor pipe in a distributor pipe cross connection on main distributor pipe, have one to discharge pore respectively in vertical direction, the vertical direction both sides of main second circumference of distributor pipe tube wall, on second circumference of each distributor pipe tube wall, be distributed with many row's distributor pipe ventholes.
Adopt the gas distributor of said structure that chlorine, acetylene gas are evenly distributed, effectively improved the product yield of acetylene chlorination tower, the purity height of thick tetrachloroethanes has further reduced the raw material consumption of trichloro-ethylene.And avoided the generation of chlorination tower blast, guaranteed safety in production.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the B-B profile of Fig. 1.
Fig. 4 has represented the master, has propped up the assembly relation of distributor pipe.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, the acetylene chlorination tower new gas distributor of the utility model, it has main distributor pipe 1, main distributor pipe two ends are horizontally connected with a short distributor pipe 2, the middle part is horizontally connected with the distributor pipe 4 of drawing money on credit, short distributor pipe, draw money on credit have between the distributor pipe in distributor pipe 3 cross connection on main distributor pipe, have one to discharge pore 101 respectively in vertical direction, the vertical direction both sides of main second circumference of distributor pipe tube wall, on second circumference of each distributor pipe tube wall, be distributed with many row's distributor pipe ventholes 301.
During use, pack into the distributor of the utility model in the acetylene chlorination tower after, at the two ends of each distributor pipe closure plate 5 is installed, and is fixed on by U-bolt 10 on the installed part of acetylene chlorination inner wall of tower.At the end of main distributor pipe another closure plate 6 is installed, and is fixed on the installed part of acetylene chlorination inner wall of tower by another U-bolt 11.Each distributor pipe can pass main distributor pipe, has through hole 302 to communicate with main distributor pipe inner chamber on the distributor pipe.The nut 8 that passes main, as to prop up distributor pipe bolt 7 and bolt two ends will be led, a distributor pipe is fixed together.Gas enters from the port 9 that main distributor pipe is exposed at acetylene chlorination tower outside, and the venthole on each pipe is distributed in the acetylene chlorination tower.
