Abstract
The invention disclosesa reactor for generating tetrachloroethylene, wherein the reactor contains a reactor body fixed with a feed port and a feed port and a discharge port at the upper, connected with a mixer with a nozzle by flange at the upper and fixed with an electric heater at the outer wall which is secured at the support ring of the outer wall of the reactor by bolt. The reactor is specially used in the production of tetrachloroethylene by thermal chlorination process, and the reactor is convenient in installation and maintenance, has a high produce capacity and a simple operation, is security in use, and low in investment.
Description
Technical field
The present invention relates to a kind of chemical industry and produce the reactor that the reactor of zellon, particularly thermal chlorination are produced zellon.
Background technology
Traditional production zellon reactor generally is a clad vessel, and housing is steel, and inner lining material is a refractory brick; Need additional two welding machines and lighter for ignition simultaneously, by the igniting initiation reaction.It is that installation and maintenance bother, need carry out the baker operation that there is shortcoming in this reactor, and the intensification cycle is long, fouling is difficult to clear up, refractory brick easily comes off blocking pipe, and lighter for ignition is easily to consume device, and maintenance is changed frequently, the expense height.
CN1050115C is disclosed by chlorination 1, and the industrial ring-like reactor that the 2-ethylene dichloride is produced trieline and tetrachloroethylene is a piston flow reactor, and each mixing of materials poor effect is unfavorable for the generation of zellon, and production capacity is restricted simultaneously.
Summary of the invention
The objective of the invention is at weak point of the prior art, a kind of reactor of novel production zellon is provided.This reactor comprises reactor body, and reactor body top is provided with opening for feed and discharge port, the mixing tank that described reactor body top band connects by flange, and described reactor body outer wall is connected with electric heater by bolt.
Described reactor body is a container.
Described electric heater divides two sections to be connected the reactor body outer wall by bolt.
Described electric heater is an electrically heated watt formula, is made up of the casting brasses that bolt is connected on the reactor body outer wall.
Two sections power of described electric heater can be identical, can be inequality.
Described reactor body, material can be that nickel, nickel-base alloy or nickel-base alloy are compound.
Described reactor body, material can be high temperature resistant nickel-base alloy, carbon steel or stainless steel.
Described reactor body, material are Monel, Ying Kang 600, nickel or 304H etc.
Described reactor body can be welding with being connected of mixing tank.
Described reactor body is connected with electric heater can be welding.
The present invention compares with pre-existing reactors, has the following advantages and beneficial effect:
(1) this reactor does not have lighter for ignition; adopt the reactor outer wall directly to install electric heater additional; make reactor be warming up to temperature of reaction; thereby initiation reaction; the opening for feed of reactor is equipped with mixing tank; guarantee mixed effect, and make the interior material of reactor be in the state of abundant back-mixing, realize good transformation efficiency.
(2) the reactor outer wall is directly installed electric heater, and reactor need not toast, can by electric heater be warmed up to the reaction temperature required after, drivings that can directly feed intake, the shortening driving time, it is easy and simple to handle to drive.
(3) electric heater can directly heat up in the reactor body outside, does not need to heat up by other medium the intensification simple and fast.
(4) because of after the reactor linings improvement, need not to build stove, shorten and install and maintenance cycle; There is not loss of sheet brick blocking pipe incident.
(5) reactor is added with mixing tank outward, makes the raw material thorough mixing, improves the effect of reaction.
(6) the Flow of Goods and Materials form is high turbulence and back-mixing state in the reactor, mix rapidly, compare, have long characteristics of the residence time with ring-like reactor, be suitable for the production of zellon, be suitable for especially utilizing in the process of tetracol phenixin for the raw material production zellon.
(7) this reactor uses Steel Vessel, withstand voltage height, and safe in utilization, repair rate is low.
