Abstract
The invention provides a spray pyrolysis device, which belongs to the technical field of chemical equipment. The spray pyrolysis device is mainly composed of a pyrolysis unit and a jacket, wherein the shell of the pyrolysis unit is provided with a feeding pipe, a blanking pipe and a gas phase pipe, a heating medium is introduced into the jacket, the outlet of the feeding pipe is connected with a plurality of nozzles, a plurality of temperature measurement points are arranged in the shell of the pyrolysis unit, and a PLC controller is mounted out of the pyrolysis unit and carries out interlocking control on feeding flow of the pyrolysis unit and flow of the heating medium in the jacket according to temperature data obtained at the temperature measurement points. According to the invention, through arrangement of the nozzles at the end of the feeding pipe, a raw material can be delivered into the pyrolysis unit in a spray pattern; the atomized raw material has a small particle size, a fast flowing speed and a good heating effect, so the speed of a pyrolysis reaction is fast, retention time of the material is short, the rate of pyrolysis is substantially improved, the pyrolysis rate of the spray pyrolysis device can reach 70 to 80%, and energy consumption in pyrolysis is reduced; meanwhile, by-products of pyrolysis are reduced, and the proportion of the pyrolysis by-products can be decreased to less than 1%.
Description
Technical field
The invention belongs to the chemical device technical field, be specifically related to a kind of spraying cracker.
Background technology
In petrochemical production process, cracking reaction belongs to a kind of common reactant, cracking reaction is that the long chain reaction thing is at high temperature fragmented into the short chain product, present cracking reactor mainly is comprised of cracker and chuck, cracker arranges feed pipe and discharge nozzle, chuck is used for passing into heat medium to the cracking that heats up of the raw material in the cracker, it is liquid that raw material mostly is greatly, liquid material enters the heat transfer of passing through heat medium in the chuck in the cracker, heating up, cracking reaction occurs, and there is following defective in such cracking process: liquid material enters in the cracker, and the liquid size ratio is larger, heat medium is slow to its heat transfer rate in the chuck, and liquid material is heated also inhomogeneously in cracker, causes the cracking time of staying long, and by-products content is higher, cleavage rate is also undesirable, the cleavage rate of such cracker is generally 50～60%, and the accessory substance of generation is up to 10%, and residence time of material is long, heat-transfer effect is poor, and energy consumption is also larger.
Summary of the invention
The invention provides a kind of spraying cracker, the cleavage rate that prior art exists is low to solve, accessory substance mainly with and the large problem of energy consumption.
The present invention mainly is comprised of cracker and chuck, the cracker housing arranges feed pipe, tremie pipe and gas phase pipe, pass into heat medium in the chuck, the outlet that solves technical scheme that its technical problem adopts and be feed pipe connects some nozzles, some points for measuring temperature are set in the cracker housing, PLC controller of cracker outer setting, the PLC controller carries out chain control according to the temperature data of point for measuring temperature to the flow of heat medium in the feed rate of cracker and the chuck.
Said nozzle is the solid conical nozzle.
Heat medium in the above-mentioned chuck is conduction oil or steam.
Compared with prior art, beneficial effect of the present invention is:
By at the feed pipe end nozzle being set, thereby raw material can be delivered in the cracker with spray pattern, raw material particle size under the spray pattern is little, flowing velocity is fast, and it is effective to be heated, so cracking reaction speed is fast, residence time of material is short, greatly improved the cracking reaction rate, the cleavage rate of apparatus of the present invention can reach 70～80%, has reduced the cracking reaction energy consumption; The cracking reaction accessory substance reduces simultaneously, and cracking accessory substance ratio can be down in 1%.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1 cracker housing, 2 chucks, 3 feed pipes, 4 nozzles, 5 tremie pipes, 6 gas phase pipes, 7PLC controller, 8 points for measuring temperature among the figure.
The specific embodiment
A kind of spraying cracker, mainly formed by cracker and chuck 2, cracker housing 1 arranges feed pipe 3, tremie pipe 5 and gas phase pipe 6, pass into the heat medium conduction oil in the chuck 2, the outlet of feed pipe 3 connects some nozzles 4, nozzle 4 is the solid conical nozzle, the cracker shell, 1 interiorly arranges some points for measuring temperature 8, PLC controller 7 of cracker outer setting, PLC controller 7 carries out chain control according to the temperature data of point for measuring temperature 8 to the feed rate of cracker and the flow of chuck 2 interior heat mediums, is controlled at the volatilization temperature point of gaseous component to guarantee cracker housing 1 temperature.
When apparatus of the present invention are used, the raw material of pressurization is by the nozzle of cracker feed pipe 3 outlets, change into spray pattern, raw material after the atomizing enter in the cracker by with the heat medium heat exchange of chuck 2, carry out cracking reaction, the light component that generates is by 6 extraction of gas phase pipe, recombinate to divide by tremie pipe 5 outflows and enter next operation or circulation cracking, the PLC controller carries out chain control according to the temperature data of point for measuring temperature 8 to the feed rate of cracker and the flow of chuck 2 interior heat mediums, is controlled at the volatilization temperature point of gaseous component to guarantee cracker housing 1 temperature.
Claims (3)
