A quality control system for storage tank ammonium nitrate aqueous solution

Abstract

The invention provides a quality control system for a storage tank ammonium nitrate aqueous solution, comprising a storage tank, the upper part of the storage tank is provided with a filter, and the filter communicates with the top of the storage tank through a pipeline; the inside of the storage tank is respectively equipped with Horizontally arranged air distributor and heating pipe, the air distributor is connected with the air compressor outside the storage tank through the first pipeline; the outlet end at the bottom of the storage tank is connected with a circulation pump, and the circulation delivery pump The outlet end communicates with the upper end of the storage tank through the second pipeline; the top end of the storage tank is connected with an acid-base tank for adjusting the pH value. This control system controls the concentration, PH value, combustion residue, and solution temperature indicators of the ammonium nitrate aqueous solution, so that it can fully meet the standard requirements or customer needs, and ensure its safe use.

Description

technical field [0001] The invention relates to the technical field of ammonium nitrate aqueous solution, in particular to a system capable of comprehensively controlling the concentration, pH value, combustion residue, temperature and quality of a finished ammonium nitrate aqueous solution in a storage tank. Background technique [0002] Pure ammonium nitrate (NH 4 NO 3 ) is stable at room temperature and is not sensitive to shock, impact or friction. However, it will explode in the presence of high temperature, high pressure and oxidizable substances. Therefore, safety regulations must be strictly observed in production, storage and use. [0003] Because the ammonium nitrate aqueous solution can greatly reduce the amount of steam used in the production process, ensure the safety of the product during the transportation process, reduce the labor cost of the production enterprise, and realize the intrinsic safety of chemical production. As an environmentally friendly pro...

AI Technical Summary

Problems solved by technology

[0006] 1. Since ammonium nitrate aqueous solution is a heat-concentrated substance, the degree of hydrolysis of ammonium nitrate varies at different temperatures, different water contents, and during long-term storage and transportation, resulting in changes in its concentration, pH value, and combustion residues;

[0007] 2. Due to factors such as raw acid concentration, ammonia pressure fluctuations or load adjustments, the concentration of the produced ammonium nitrate aqueous solution changes frequently;

[0008] 3. Because ammonium nitrate has the danger of explosion under high temperature, high pressure, presence of oxidizable substances (reducing agents) and electric sparks
