Organic acid ammonia gas decontaminant, preparation method therefor and application thereof

Abstract

The present invention discloses an organic acid ammonia gas decontaminant, a preparation method therefor and an application thereof. The decontaminant comprises organic acid, a surfactant and water, wherein the amount of substance concentration of the organic acid is 0.01 mol / L-0.09 mole / L, and the amount of substance concentration of the surfactant is 0.03 mol / L. The decontaminant, the preparation method therefor and the application thereof have the following advantages: (1) shortcomings that when used for decontaminating leaked ammonia gas, a conventional pure water curtain is low in decontamination efficiency, decontamination products are not stable, and secondary pollution on the environment is easily caused are overcome; according to the decontaminant disclosed by the present invention, ammonia gas decontamination efficiency is improved, and the effect of stopping the leaked ammonia gas from spreading by using a water curtain is enhanced; (2) the organic acid ammonia gas decontaminant disclosed by the present invention has relatively weak acidity, corrosion on equipment is low, and decontamination products have little influence on the environment; and (3) the preparation method is easy, raw materials are inexpensive and easy to obtain, and the organic acid ammonia gas decontaminant is suitable for a fire protection water curtain.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, relates to the field of using a decontaminant to decontaminate leaked ammonia gas, in particular to an organic acid ammonia gas decontaminant and its preparation method and application. Background technique [0002] Ammonia is a colorless gas with a strong pungent smell, easily soluble in water, and is an explosive gas with a lower explosion limit of 15.7% in air. Low concentrations of ammonia can stimulate mucous membranes, and high concentrations of ammonia can cause tissue dissolution and necrosis. The manifestations of acute ammonia poisoning are as follows: in mild cases, tearing, sore throat, hoarseness, cough, sputum, etc.; conjunctiva, nasal mucosa, and pharynx congestion and edema; chest X-ray signs consistent with peribronchitis. The above-mentioned poisoning symptoms will be aggravated when the inhalation concentration of ammonia gas increases, and dyspnea and cyanosi...

AI Technical Summary

Problems solved by technology

Decontamination of leaked ammonia gas with pure water curtain has poor decontamination efficiency, and ammonia cannot be completely decontaminated; the decontamination product ammonia water is unstable and highly corrosive, which easily causes secondary pollution

However, most of the current decontamination experiments are pre-leaked quantitative gas and then decontamination, which does not match the reality. The obtained theory and data cannot effectively support the application of water curtain decontamination.
