Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the embodiments of the accompanying drawings.

[0026] A reactor for the production of tetrachlorethylene as shown in the figure includes 1. a reactor body, 2. an electric heater, 3. a discharge port, 4. a mixer, and 5. a feed port.

[0027] After the temperature of the reactor is raised to the temperature required by the reaction through the electric heater 2, the raw materials are mixed through the feed port 5 to the mixer 4, and then enter the reactor 1 for reaction, and the reacted material is discharged from the feed port 3 for reaction. device.

[0028] Two examples of using this device to produce tetrachlorethylene:

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 [0001] The invention relates to a reactor for producing tetrachlorethylene in the chemical industry, in particular to a reactor for producing tetrachlorethylene by thermal chlorination. Background technique [0002] The traditional tetrachlorethylene production reactor is generally a lined container, the shell is made of steel, and the lining material is refractory bricks; at the same time, two electric welding machines and igniters are required to initiate the reaction through ignition. The disadvantages of this reactor are that installation and maintenance are troublesome, oven operation is required, the heating cycle is long, scaling is difficult to clean, refractory bricks are easy to fall off and block the pipeline, the igniter is a consumable device, frequent maintenance and replacement, and high cost. [0003] CN1050115C disclosed by chlorination of 1,2-dichloroethane to produce trichlorethylene and perchlorethylene industrial ring reactor is plug flow...
