Example Embodiment

[0024] Please refer to Figure 1 to Figure 2 As shown, it shows the specific structure of the preferred embodiment of the present invention, which includes a vent pipe 10, a lye storage tank 20, a lye circulation pump 30, a nozzle 40, and an exhaust fan 50.

[0025] The ventilation pipe 10 receives the exhaust gas discharged from the system. Specifically, a steam-water separation tank 61 is arranged on the side of the ventilation pipe 10, and the acidic waste gas is stored in the steam-water separation tank 61. The acidic waste gas in the steam-water separation tank 61 passes through a vacuum pump 62 is pressed into the ventilation pipe 10; the ventilation pipe 10 is provided with an observation mirror 11 for observing the inside of the ventilation pipe 10.

[0026] The lye storage tank 20 is in communication with the lye return port at the lower end of the ventilation pipe 10, and a valve 41 is provided at the outlet of the lye storage tank 20 to control the amount of lye output. ...

Abstract

The invention discloses a simple acid waste gas purification apparatus, which comprises a ventilating pipe, an alkali liquor storage tank, an alkali liquor circulating pump, nozzles and an exhaust fan. The acid waste gas is sucked into the ventilating pipe, the alkali liquor storage tank is communicated with an alkali liquor reflux inlet in the lower end of the ventilating pipe; alkali liquor in the alkali liquor storage tank is sucked into the alkali liquor circulating pump; the nozzles are mounted in the ventilating pipe, the alkali liquor is pumped into the nozzles through the alkali liquorcirculating pump; the exhaust fan is arranged at an air outlet of the ventilating pipe, and the neutralized residual waste gas is discharged out of the ventilating pipe through the exhaust fan. Through sucking the acid gas and the alkali liquor into the ventilating pipe for neutralization reaction, the acid gas is removed, a reactant generated after the neutralization of the acid gas and the alkali liquor and residual alkali liquor reflows to the alkali liquor storage tank for cyclic utilization, neutralized acid-free waste gas is discharged, so that the national emission standard is met. Inaddition, the simple acid waste gas purification apparatus is easy to install, the adjustable atomizing nozzles are arranged at optional positions in the pipeline, no filler is needed, the configuration is flexible, and the treatment efficiency, especially to small-scale flue gas, is high.

Description

technical field [0001] The invention relates to the technology in the field of gas treatment equipment, in particular to a simple acid waste gas purification device. Background technique [0002] As the country's requirements for environmental protection become more and more stringent, almost all industrial tail gases must meet the emission standards required by environmental protection, otherwise they will not be produced. [0003] For the treatment of tail gas containing acid mist, only large-scale devices used to have it. Power wave flue gas purification technology is usually used. Packing is placed in the flue or purification tower through which the flue gas passes, and the lye is pumped to the purification tower or pipeline for spraying. Convection with the flue gas, the role of the filler is to increase the contact area, so that the flue gas can contact with the lye as much as possible for a chemical neutralization reaction, but most of the neutralized reactants will a...
