Flue gas treatment fluid special for hot chamber die casting machine

Abstract

The invention discloses flue gas treatment fluid special for a hot chamber die casting machine. The flue gas treatment fluid is prepared from the following raw materials in parts by weight: 100-150 parts of deionized water, 10-15 parts of methylisobutylketone, 5-8 parts of zeolite powder, 5-12 parts of maleic anhydride, 20-40 parts of xylene, 15-25 parts of n-butyl alcohol, 4-8 parts of dimethylformamide, 10-15 parts of ethylene glycol, 3-9 parts of triisopropylphenyl, 5-12 parts of citric acid, 2-8 parts of sodium hypochlorite, 6-12 parts of N-ethylenediamine dihydrochloride, 2-4 parts of monoethanolamine, 1-5 parts of trimethylpentane, 2-8 parts of isooctane, 1-3 parts of sodium pyrophosphate, 1-2 parts of sulfonated cobalt phthalocyanine, 2-4 parts of hexamethylphosphoramide, 5-12 partsof complex fibers and 6-15 parts of compound colloid. According to the flue gas treatment fluid disclosed by the invention, flue gas produced during operation of the hot chamber die casting machine is treated, so that the emitted flue gas does not contain any pollutant, and the flue gas treatment fluid is environmentally friendly to atmosphere and harmless to a human body.

Description

technical field [0001] The invention relates to the technical field of die-casting machines, in particular to a special flue gas treatment liquid for hot-chamber die-casting machines. Background technique [0002] At present, the commonly used die casting processes include hot chamber die casting and cold chamber die casting. Cold chamber die-casting uses liquid metal as raw material, sprays it into the mold for die-casting, and the mold wall is cooled by circulating cooling water. Hot-chamber die-casting is to make metal chips into powder and inject them into the mold for die-casting after preheating. Electric heating is generally used for preheating and mold heating. In the process of die-casting production, smoke, heat, dust, etc. will be generated. These exhaust gases and smoke contain various metal oxides and non-metal oxides, and may also contain harmful substances, which may pollute the environment. [0003] According to the regulations of the environmental protecti...
