Three-acid waste gas purifying machine

Abstract

The invention relates to a three-acid waste gas purifying machine. The three-acid waste gas purifying machine comprises a three-acid gas purifying device, a vapor condensation apparatus and a vapor drying device, the three-acid gas purifying device is composed of a purifier housing, a housing separator plate, an impact curved slab, a high-pressure spray pipe group, an air-water mixing layer, a water-replenishing tank, a water pump case, an exhaust gas air-inlet pipe and a purifier outlet duct; the vapor condensation apparatus and the three-acid gas purifying device have a same structure; the vapor drying device comprises a a drying device housing, an inner cylinder, an intermediate cylinder, a drying device air inlet pipe, a drying device exhaust pipe, a water-stop sheet and a support plate. The three-acid waste gas purifying machine has high purifying efficiency, the gas discharged in atmosphere has no peculiar smell, the structure is simple and requires no maintenance, the equipment cost is low, and the three-acid waste gas purifying machine is convenient for popularization and application. the device with passed vapor is prepared by corrosion-resistant plastic materials, corrosivity is strong, corrosion damage can be avoided, and purifying quality can be guaranteed for long-term.

Description

technical field [0001] The invention relates to a waste gas purifier, in particular to a tri-acid waste gas purifier. Background technique [0002] Nitric acid, phosphoric acid and sulfuric acid are used to oxidize the metal surface in the oxidation workshop. These three gases are very irritating to the human respiratory system, and their discharge into the atmosphere is very polluting to the environment and seriously affects people's health. The current equipment It is mainly treated by spraying equipment and electrostatic treatment equipment, which is difficult to clean, and it is highly corrosive to the treatment equipment, and the equipment is easily damaged and seriously affects the purification quality. Therefore, it is necessary to study a three-acid waste gas purifier. Contents of the invention [0003] The object of the present invention is to provide a three-acid waste gas purifier for the above problems. [0004] The technical solution adopted in the present in...
