Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sulfuric acid diluter, specifically is a silicon carbide sulfuric acid diluter. BACKGROUND

[0002] The diamond sand is also called silicon carbide (SiC), which is made of quartz sand, petroleum coke (or coal coke), wood chips (salt is needed when producing green silicon carbide) and other raw materials through high-temperature smelting of resistance furnace. Silicon carbide is a rare mineral in nature, which is called moissanite. Silicon carbide is also called carborundum. Among the non-oxide high-tech refractory materials such as C, N and B in the present era, silicon carbide is the most widely used and most economical one, which can be called diamond sand or refractory sand. Sulfuric acid (chemical formula: H2SO4) is the most important oxygen-containing acid of sulfur. Anhydrous sulfuric acid is a colorless oily liquid, which crystallizes at 10.36℃. The water solution with different concentrations of sulfuric acid is usually used, which is prepared by tower method and contact method. The former can obtain crude dilute sulfuric acid with a mass fraction of about 75%, and the latter can obtain pure concentrated sulfuric acid with a mass fraction of 98.3%. The boiling point of sulfuric acid is 338℃, and the relative density is 1.84. The existing patent, patent publication number CN208320515U, discloses a sulfuric acid diluter, which belongs to the field of sulfuric acid processing. The sulfuric acid diluter comprises a mixer, a silicon carbide heat exchanger and a cooler. The mixer has a mixing channel inside along a preset direction. The silicon carbide heat exchanger has a heat exchange channel inside, which has a heat exchange inlet and a heat exchange outlet along the preset direction in sequence. The cooler has an accommodating cavity inside, and the silicon carbide heat exchanger is arranged in the accommodating cavity along the preset direction. The inner wall of the cooler and the outer wall of the silicon carbide heat exchanger jointly define a cooling space, and the outer wall of the cooler is spaced apart to be provided with a cooling water inlet and a cooling water outlet, which are connected with the cooling space. The sulfuric acid diluter can effectively dilute concentrated sulfuric acid and effectively cool the dilute sulfuric acid.
