Embodiment Construction

[0046]The present invention will be described in further detail below through examples. A kind of organic acid ammonia gas decontamination agent, comprises organic acid, surfactant and water, and wherein specific proportion is as shown in table 1: prepare the organic acid decontamination agent that meets the requirements respectively according to table 1, wherein surfactant adopts emulsifier OP-10, and the concentration of substances in the decontamination agent is 0.03mol / L.

[0047] Table 1 embodiment 1~6 decontamination agent proportioning

[0048]

[0049] The test system using the water curtain to decontaminate the leakage of ammonia gas is used to test the comparative example and the organic acid ammonia gas decontamination agent prepared in Examples 1 to 6 is applied to the fire water curtain to decontaminate the leakage of ammonia gas.

[0050] like Figure 8 As shown, the test system for the effect of decontaminating and leaking ammonia with the water curtain is ...

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...
