Quality control system of storage tank ammonium nitrate water solution

Abstract

The invention provides a quality control system of a storage tank ammonium nitrate water solution, which comprises a storage tank, wherein the upper part of the storage tank is provided with a filter; the filter is communicated with the top end of the storage tank through a pipeline; the inside of the storage tank is respectively provided with an air distributor and a heating tube; the air distributor is connected with an air compressor arranged outside the storage tank through a first pipeline; an outlet end positioned at the bottom end of the storage tank is connected with a circulating delivery pump; an outlet end of the circulating delivery pump is communicated with the upper end of the storage tank through a second pipeline; and the top end of the storage tank is connected with an acid-alkali tank for regulating the PH value. The control system can control the concentration, PH value, combustion residue and solution temperature index of the ammonium nitrate water solution, so that the ammonium nitrate water solution can comprehensively satisfy the standard requirements or demands of customers, and ensure the use safety.

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. [0002] Background technique [0003] 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. [0004] 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 fr...

AI Technical Summary

Problems solved by technology

[0007] 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;

[0008] 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;

[0009] 3. Because ammonium nitrate has the danger of explosion under high temperature, high pressure, presence of oxidizable substances (reducing agents) and electric sparks
