Combined graphite concentrated acid dilution cooler

Abstract

The invention discloses a combined graphite concentrated acid dilution cooler which comprises a housing, a graphite cooling block arranged in the housing, and a graphite acid mixing barrel arranged on the graphite cooling block, wherein the graphite acid mixing barrel is provided with a mixing chamber; a material cooling hole and a first refrigerant hole which are vertical to each other are formed in the graphite cooling block; the material cooling hole is communicated with the mixing chamber; the first refrigerant hole is communicated with a hollow cavity between the housing and a graphite cooler; a graphite condensation block is arranged on the graphite acid mixing barrel; a material condensation hole and a plurality of second refrigerant holes are formed in the graphite condensation block; the material condensation hole is vertical to the second refrigerant holes and is not communicated with the second refrigerant holes; the second refrigerant holes are communicated with the hollow cavity; the material condensation hole runs through the upper surface and the lower surface of the graphite cooling block; the first refrigerant hole and the second condensation hole are horizontally arranged; and the graphite acid mixing barrel is provided with a concentrated acid inlet pipe and a water inlet pipe communicated with the mixing chamber. Acid mist generated by concentrated acid during dilution can be recovered in same equipment, so that the waste is reduced.

Description

technical field [0001] The invention specifically relates to a combined graphite concentrated acid dilution cooler. Background technique [0002] When some liquid materials (such as 98% sulfuric acid) are mixed with diluents (such as water), a large amount of heat of reaction (or heat of dilution) will be released, which will heat up the diluent and even boil it. For example, when 98% sulfuric acid at a temperature of about 30°C is diluted with water to 40-65%, the heat of dilution will cause the mixed acid to boil, thereby generating acid mist. At this time, the usual emergency measures are to export the acid mist to the dilution cooler, or directly send it into the atmosphere with a pipeline, or enter it into the next equipment to absorb it with water or condense it into dilute acid for further treatment, thereby causing air pollution, material, and energy consumption. waste. Contents of the invention [0003] In order to solve the above problems, the present invention...
