Titanium dioxide chloride oxidation device cooling water purification method and circulation system

Abstract

The invention discloses a titanium dioxide chloride oxidation device cooling water purification method and a circulation system, relates to the titanium dioxide chloride industry, and solves the problems that the cooling water of the existing titanium dioxide chloride oxidation device is easy to form incrustation on the outer surface of a cooling guide pipe and the heat exchange efficiency of thecooling guide pipe is influenced. According to the technical scheme, an inlet and an outlet of a cooling guide pipe of the titanium dioxide chloride oxidation device are connected with an oxidation bag filter and an oxidation furnace outlet respectively, the cooling guide pipe exchanges heat with cooling water in a cooling pool, and a purification device softens the cooling water. The titanium dioxide chloride oxidation device cooling water circulation system comprises the cooling guide pipe, the cooling pool and a circulation water tank, the cooling guide pipe is located in the cooling pool,a water inlet pipe and a water return pipe are arranged between the cooling pool and the circulation water tank to form a circulation pipeline, and the water inlet pipe and/or the circulation water tank and/or the cooling pool are/is provided with the purification device. And the purification device reduces the hardness of cooling water and effectively relieves the problem of scaling on the surface of the cooling guide pipe.

Description

technical field [0001] The invention relates to the titanium dioxide chloride industry, in particular to a method and system for purifying cooling water of a titanium chloride oxidation device. Background technique [0002] For the titanium chloride oxidation device of the titanium chloride white plant, the refined titanium and oxygen enter the cooling duct to cool after reacting in the oxidation furnace. After cooling, they enter the oxidation bag filter for gas-solid separation, and the circulating chlorine gas returns to the chlorination furnace for recycling. The primary product of titanium dioxide enters the beating tank for beating. [0003] The cooling conduit is installed in the cooling pool, and the cooling pool is equipped with circulating water that has not passed through the main part of the cooling conduit. The cooling pool is also connected to the water inlet pipe, and the water inlet pipe and the return water pipe are connected to the circulating water tank to...
