Problems solved by technology

[0003] However, during the use of the traditional concentrated hydrochloric acid recovery mechanism for hydrochloric acid regeneration, spray roasting is used for recovery. However, after roasting in this way, fine iron powder shells will be discharged into the atmosphere, causing pollution.
Moreover, the traditional roasting method is not good, and the roasting is not complete enough

Abstract

The invention belongs to the field of waste acid regeneration recycling, and more specifically relates to a concentrated hydrochloric acid recycling mechanism used for hydrochloric acid regeneration.The concentrated hydrochloric acid recycling mechanism used for hydrochloric acid regeneration comprises a roasting furnace, a feeding mechanism, a fixed supporting mechanism, a condensation mechanism, a collecting mechanism, a roasting mechanism, a shocking mechanism, and a driving mechanism; the feeding mechanism which is used for introducing waste acid liquid into the roasting furnace is connected with the top end of the roasting furnace; the roasting mechanism which is used for roasting waste acid liquid after atomization is arranged at the bottom of the inner cavity of the roasting furnace; the roasting mechanism comprises fixing rods, a fixing pedestal, an electric heating plate, a dust falling plate, and first springs; the shocking mechanism which is used for shocking down of iron powder particles formed on the surface of the dust falling plate after waste acid liquid roasting evaporation is arranged in the fixing pedestal; and the driving mechanism which is used for generatingcompressed air to push an impacting block to impact the dust falling plate is arranged in the fixing pedestal. The concentrated hydrochloric acid recycling mechanism can be used for shacking and collecting iron powder formed on the surface of the dust falling plate, and preventing environment pollution.

Description

technical field [0001] The invention relates to the field of waste acid regeneration and recovery devices, in particular to a concentrated hydrochloric acid recovery mechanism for hydrochloric acid regeneration. Background technique [0002] There are already many modern waste acid recovery equipment. Although the use methods of various equipment are different, the principles are mostly the same. Both use the characteristics of FeCl2 to be quantitatively hydrolyzed at high temperature in an atmosphere with sufficient water vapor and an appropriate amount of oxygen. The pre-concentrated waste hydrochloric acid is roasted in a roaster to convert the iron that exists in the form of FeCl2 in the waste hydrochloric acid. Separated for Fe2O3. [0003] However, the traditional concentrated hydrochloric acid recovery mechanism for hydrochloric acid regeneration uses the method of spray roasting to recover during use. However, after roasting in this way, fine iron powder shells will...
