Embodiment Construction

[0021] The invention is a method for preventing calcium, magnesium and iron from adhering and clogging the top of a chlorination furnace in the production of titanium tetrachloride, which can effectively solve the problem that the outlet pipe of the top of the chlorination furnace is easily blocked in the production of titanium tetrachloride , which laid the basic conditions for improving the production and use efficiency of the chlorination furnace.

[0022] It should be pointed out that the top of the chlorination furnace is equipped with an outlet pipeline, and the outlet pipeline discharges the chloride impurity gas formed by calcium, magnesium and iron.

[0023] In the present invention, a smoke exhaust and anti-blocking device is arranged on the outlet pipe, and the device includes a four-way pipe 1, an inverted conical dust collection cover 2, a pressure balance pipe 3, a first gas pipe 4, a second gas pipe 5, Spare pipes and related gate valves, although these configur...

Abstract

The invention discloses a method for preventing calcium, magnesium and iron adhesion blockage at the top of a chlorination furnace during the production of titanium tetrachloride. According to the method, an outlet pipeline arranged at the top of the chlorination furnace is connected with a second gas pipeline (5); the second gas pipeline is connected with a lower end flange of a four-way pipe (1) through a flange; an upper end flange of the four-way pipe is connected with an inverted conical dust collection hood (2) through an upper end gate valve; a left end or right end flange of the four-way pipe is connected with a first gas pipeline (4) through a first gate valve; the right end or left end of the four-way pipe is closed or opened through a side end gate valve and can be connected with a standby pipeline; a pressure balancing pipe (3) is connected between the dust collection hood and the first gas pipeline; and the process of cleaning the dust collection hood or the first gas pipeline does not influence the normal discharging of chloride impurity gas by the second gas pipeline, so that the outlet pipeline arranged at the top of the chlorination furnace surely can normally discharge the chloride impurity gas during the production of titanium tetrachloride, and blockage is not generated. The method disclosed by the invention has the characteristics of simplicity and practicability.

Description

technical field [0001] The invention belongs to the technical field of chlorination furnaces, and in particular relates to a method for preventing calcium, magnesium and iron from adhering and clogging the top of a chlorination furnace in the production of titanium tetrachloride. Background technique [0002] The production of titanium tetrachloride uses a chlorination furnace, and its gaseous reaction products are discharged from the outlet pipe on the top of the furnace, and the gaseous reaction products will be entrained with chloride impurities such as calcium, magnesium, and iron. These calcium, magnesium, and iron impurities will adhere to the inner wall of the outlet pipe, and with the prolongation of the service time of the chlorination furnace, the accumulation of calcium, magnesium, and iron impurities will become more and more, causing the inner diameter of the outlet pipe to become smaller and make the Its blockage will cause the chlorination furnace to be forced...
