Description

Technical Field

[0001] The invention relates to the technical field of hydrochloric acid production, in particular to a distillation and filtration device for hydrochloric acid production. Background Art

[0002] Industrial hydrochloric acid refers to hydrochloric acid with a concentration of 30% or 36% obtained from industrial production. Its main component is hydrogen chloride, with the chemical formula HCl and a molecular weight of 36.46. Industrial hydrochloric acid contains impurities such as iron and chlorine, and is slightly yellowish due to the mixture of Fe3+. Industrial hydrochloric acid is highly corrosive and can corrode metals. It is corrosive to animal and plant fibers and human skin. Concentrated hydrochloric acid smokes in the air and generates white clouds when it comes into contact with ammonia vapor. Hydrogen chloride gas is harmful to animals and plants. Hydrochloric acid is one of the important raw materials in the chemical industry and is widely used in chemical raw materials, dyes, medicines, food, printing and dyeing, leather, sugar making, metallurgy and other industries. It is also used in the regeneration of ion exchange resins and as a cleaning agent for electroplating and metal surfaces.

[0045] The working principle of the present invention is: when in use, it is carried on the place of use through the pile foundation pad 101, and after being carried on the place of use, the shock absorber 102 and the operating base plate 103 are used to perform effective shock absorption treatment to achieve the effect of assembling and splicing the bearing mixing component 2, the filtering component 3 and the condensing component 4. When it is necessary to filter the product, the lower valve 309 is opened, and the output power of the pump motor 3011 is used to drive the output end to operate, so that the output power of the pump motor 3011 can drive the pump body 3010 to operate, so that the material is input into the filter tube 305 through the feed inlet 3012 and the cooperation of the pump body 3010. In the process, when the material enters the filter tube 305, the material can be effectively purified and filtered through the relatively continuous isolation mesh cover 306, the activated carbon layer 307, and the filter element group 308. After the main valve block 302 and the upper valve 304 are opened, the purified material is input into the carrier chamber 201 through the inlet pipe body 301 and the node pipe 303.

During the condensation operation, the cooling fan 4012 on the duct shell 4011 is used to output power to drive the output end to operate so that the wind force can fully dissipate the heat for the fin group 407 on the inner side of the carrier shell 4010. Then the air valve block 404 is used to open the channel, so that the high-pressure steam can be output to the riser 403 through the upper cover 401, enter the branch pipe 405 at the input end of the air valve block 404, and be introduced into the dispersion pipe 406 through the branch pipe 405. With the cooperation of the dispersion pipe 406 and the fin group 407, an effective condensation effect is achieved. After condensation, the condensed product is output through the discharge port 408 to achieve a receiving effect.
