Problems solved by technology

It is believed in the industry that it is impossible to increase the spray absorption device in order to reduce the emission pollution, because adding the spray absorption device will affect the emission speed of the flue gas and increase the system resistance. accident, so other methods are only possible

Abstract

A process for processing tail gas from acidolysis main reaction in production of titanium dioxide by sulfuric acid method, wherein the device for the process comprises acidolysis tank (1), flue (2), Venturi tube (5-1), circulating cistern (6-1), and water scrubber (9), characterized in that there are Venturi tube (5-2) and air chamber (6-2) between the water scrubber (9) and end fan (7), the top end of water scrubber (9) communicates with the top end of Venturi tube (5-2) via pipe, and the lower end of Venturi tube (5-2) lies in the air chamber (6-2), whose top end communicates with end fan (7). In above process, the environmental pollution from conventional process can be reduced with effluent concentration much lower than national standard, and the discharge temperature of tail gas is lower, and tail air output is less.

Description

technical field [0001] The invention relates to a process technology for treating tail gas in the production process of titanium dioxide by sulfuric acid method, more specifically, it is a device for treating tail gas during the main reaction of acidolysis in the production of titanium dioxide by sulfuric acid method. Background technique [0002] The production process of acidolysis tail gas: Among the domestic titanium dioxide manufacturers, except Panzhihua Iron and Steel Group Jinzhou Titanium Industry Company, the remaining nearly 70 are all sulfuric acid production processes. In the production process of sulfuric acid titanium dioxide, acid hydrolysis is to dilute concentrated sulfuric acid (concentration 93-98%) with dilute waste acid (concentration is about 20%) or tap water, so that the concentration of sulfuric acid reaches 85-89%, and then use it to decompose titanium Iron ore (FeTiO 3 ), the chemical reaction formula is: [0003] FeTiO 3 +2H 2 SO 4 →Ti(SO 4...
