Description

Technical Field

[0002] When producing hydrochloric acid, the produced hydrogen chloride gas is generally passed into a hydrogen chloride absorption tank, and the hydrogen chloride gas is absorbed by the absorption liquid in the absorption tank to produce hydrochloric acid. The tail gas is then discharged through an exhaust pipe and further processed. When the hydrogen chloride absorption tank absorbs the hydrogen chloride gas, a large amount of heat is generated, so the absorption tank needs to be cooled.

[0003] After searching, the utility model patent with announcement number CN212902756U discloses a cooling system for a hydrochloric acid absorption tank, including a base and a hydrogen chloride absorption tank, a cooling pipe is wound around the hydrogen chloride absorption tank, a sealing frame is fixedly installed on the top of the base, an absorption mechanism is arranged in the sealing frame, an exhaust pipe connected with the interior of the hydrogen chloride absorption tank is fixedly installed on the hydrogen chloride absorption tank, the exhaust pipe passes through the sealing frame and extends into the absorption mechanism, a mounting frame extending into the interior is fixedly installed on the top of the sealing frame, a connecting port is opened through the bottom of the mounting frame, a sliding plate is slidably connected in the mounting frame, a cooling mechanism is arranged on the top of the sliding plate, two connecting ports are opened on the sliding plate, and the inner side walls opposite to the two connecting ports are respectively provided with mounting grooves and card grooves; the patent structure is reasonably designed, which can effectively dissipate the heat of the hydrochloric acid absorption tank, improve its heat dissipation effect, and avoid the tank body from being scattered due to excessive temperature.

[0004] However, the above patent still has the following shortcomings: although the fan can move up and down to increase the area of ​​the tank body for blowing and cooling, the fan can only blow air to the tank body from one direction, and the cooling range is uneven, which affects the cooling quality; and the gas generated by the reaction inside the absorption tank carries heat, which is not reasonably utilized, which easily leads to waste of resources. For this reason, we propose a cooling device for hydrochloric acid absorption tank. Utility Model Content
