Method for removing mud out of titanium-tetrachloride storage tank in production process of titanium tetrachloride

Abstract

The invention relates to a method for removing mud out of a titanium-tetrachloride storage tank in the production process of titanium tetrachloride, and the method is used for removing mud deposited in a crude titanium-tetrachloride storage tank in the production process of titanium tetrachloride and belongs to the technical field of titanium tetrachloride production. According to the technical scheme disclosed by the invention, the method comprises the following steps of (1) in a closed state, repeatedly and circularly impacting deposited mud in a storage tank by using the conventional feeding pump for titanium tetrachloride production, so that the deposited mud is suspended; (2) feeding the suspended mud into a thickener so as to deposit the suspended mud into mud; and (3) feeding the mud into a dust arrester by a mud recycling device so as to separate and recycle the mud. In the invention, because a closed method is adopted to transfer mud to a recycling system which can carry out mud treatment, the working environment is improved, and no pollution is caused; since no new equipment is added and the conventional feeding pump is utilized, the investment is reduced; and titanium tetrachloride is recycled, the metal recovery efficiency is improved, and waste and pollution caused by mud washing can be avoided.

Description

technical field [0001] The invention relates to a mud removal method for a titanium tetrachloride storage tank in the production of titanium tetrachloride, which is a method for removing the deposit mud of a crude titanium tetrachloride storage tank in the production of titanium tetrachloride, and belongs to the technical field of titanium tetrachloride production . Background technique [0002] At present, there is no good way to deal with the mud deposited in the crude titanium tetrachloride storage tanks of domestic titanium tetrachloride manufacturers. Generally, the relatively clean crude titanium tetrachloride is removed, and then the manhole is opened, and the artificial stand outside is worn. Masks, wearing rubber clothes, rubber boots, and rubber gloves, are pulled out with a rake, put in containers or sold or washed away with water. The problems of this method are: 1.

Problems solved by technology

[0002] At present, there is no good way to deal with the mud deposited in the crude titanium tetrachloride storage tanks of domestic titanium tetrachloride manufacturers. Generally, the relatively clean crude titanium tetrachloride is removed, and then the manhole is opened, and the artificial stand outside is worn. Mask, wearing rubber clothes, rubber boots, rubber gloves, raked out, packed in containers or sold or washed away with water

The problems of this method are: 1. The working conditions are quite harsh, especially in summer, the smoke is heavy, choking and irritating to the skin, and it cannot be cleaned normally; 2. The surrounding environment is affected, the environment is damaged, and the environmental protection problem is big; The mud contains up to 70% titanium tetrachloride, and it is wasteful and polluting to wash it away; 4. It consumes a lot of manpower
