Electric quantity neutralization agent and preparation thereof

Abstract

The invention relates to an electric quantity neutralizer and a preparation method thereof. The method of the invention can effectively overcome the defects in the prior art and solve the problems ofhigh cost, high labor intensity, environmental pollution and corrosion to facilities in the production of the electric quantity neutralizer. The electric quantity neutralizer is prepared by 116kg of aluminium hydroxide, 160kg of hydrochloric acid, 70kg of sulfuric acid, 5kg of regulator, 200kg of water, polymine and cationic etherifying agent. The preparation method of the invention comprises thesteps that the water, the aluminum hydroxide, the hydrochloric acid and the sulfuric acid are added into a reaction tank according to the group component to be evenly stirred and a steam valve is opened; after the reaction is carried out for 5 hours, the regulator is added into the reaction tank according to the group component for reaction for another 2 hours; material after the reaction are conveyed into a settling basin for settlement for 4 to 6 hours; a supernatant is pumped into a drying tower by a liquid injection pump for being dried to obtain dry solids; the dry solids are then taken out of the drying tower and every 800kg of the dry solids are added with 190kg of the polymine and 10kg of the cationic etherifying agent to be evenly mixed in a mixer. Meanwhile, the preparation method of the invention has the advantages of scientific ingredient combination, easy preparation, low cost and enormous economic and social benefits.

Description

1. Technical field [0001] The invention relates to the field of chemical industry, in particular to a charge neutralizing agent and a preparation method thereof (the charge neutralizing agent is also called an anion capture agent or retention and drainage aid). 2. Background technology [0002] Electricity neutralizers are commonly used in chemical production, and the most commonly used ones are as follows: [0003] A. Use industrial aluminum shavings or aluminum ash as the raw material. The main component of the raw material is aluminum, which can be directly reacted with hydrochloric acid, hydrolyzed and polymerized to obtain a certain basicity product. The reaction formula is as follows (Note: Al(OH) x Cl y for PAC product structure): [0004] Al+HCl+H 2 O→Al(OH) x Cl y +H 2 ↑(of which x , y is a natural positive integer) [0005] This method has the advantages of simple process and sufficient reaction, and the basicity of the product can be controlled by adjusti...

Problems solved by technology

[0017] In view of the above situation, the purpose of the present invention is to provide a new electricity neutralizer and its preparation method, which can effectively overcome the deficiencies in the prior art, and solve the problems of high cost, heavy labor, environmental pollution and environmental impact in the production of electricity neutralizers. The technical solution to the corrosion problem of equipment is that the electricity neutralizer is made of 116kg of aluminum hydroxide, 160kg of hydrochloric acid, 70kg of sulfuric acid, 5kg of regulator, 200kg of water (kml), polyethyleneimine and cationic etherification agent. Its production method is to add water, aluminum hydroxide, hydrochloric acid and sulfuric acid into the reaction tank according to the component amount, stir evenly, open the steam valve, and react at 95-105°C for 5 hours, then add the component amount adjuster, React at 105°C for 2 hours, send the reacted material into the sedimentation tank for 4-6 hours, and put the supernatant into the drying tower through a liquid spray pump to dry to obtain a dry solid, which is taken out from the drying tower and passed through a mixer. Add 190kg of polyethyleneimine (solid) and 10kg of cationic etherification agent to every 800kg of dry solids, mix evenly, and then measure and pack
