Abstract

The invention discloses a chemical plant exhaust gas purification method. A purifying agent is composed of a solution A and a solution B in a weight component ratio of 1:1. The solution A comprises the following raw materials by weight: 45-60 parts of lime, 3-5 parts of sodium carbonate, 6-9 parts of alkaline aluminum sulfate, 10-15 parts of ferric oxide, 6-9 parts of aluminum oxide, and 90-120 parts of water. The solution B comprises the following raw materials by weight: 20-45 parts of urea and 3-5 parts of sodium hypochlorite. Through proportioning of the solution A and solution B, the chemical plant exhaust gas purification method provided by the invention makes the ratio of the purifying agent clearer and more concise and the proportioning efficiency higher, at the same time the fluegas treatment method is simple and convenient, purification treatment of flue gas can be realized without complicated device, and the practicability is higher.

Description

Technical field [0001] The present invention relates to the technical field of purifiers, in particular to a method for purifying exhaust gas from a chemical plant. Background technique [0002] Sulfides and nitrates are pollutants in industrial production, which bring greater pollution to the environment. If the pollutants cannot be effectively eliminated, it will affect people's health. Especially in thermal power generation, more sulfides and nitrates are produced. The treatment of sulfides and nitrates is a problem we need to face. The development of a new type of purifier will improve the effect of air purification. Summary of the invention [0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and proposes a method for purifying exhaust gas from a chemical plant. [0004] In order to achieve the above objectives, the present invention adopts the following technical solutions: [0005] A purifying agent, which is a combination of A...
