Description

Water seal liquid desorption and recovery device for acid making flue gas pipeline

Technical Field

The utility model relates to a processing technology of making sour flue gas is smelted to copper, concretely relates to system sour flue gas pipeline water seal liquid desorption recovery unit.

Background

Along with the enhancement of environmental protection consciousness, environmental protection laws and regulations are gradually sound, environmental protection law enforcement dynamics is continuously enhanced, atmospheric pollution is more and more emphasized, and as copper smelting enterprises, it is vital that unorganized dissipation of copper smelting smoke is processed. In order to protect production equipment, a safety water seal is arranged on a flue gas pipeline, and the water seal can prevent smelting flue gas (SO) under normal conditions₂) When the pressure in the flue gas pipeline changes and the water sealing liquid overflows when the pressure is dissipated but the production fluctuates, and the SO dissolved in the water sealing liquid overflows at the moment₂Can be resolved out from water and pollute the environment.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a system sour flue gas pipeline water seal liquid desorption recovery unit to effectively stop the pollution that water seal liquid spills over and causes the environment.

In order to achieve the purpose, the utility model discloses a following technical scheme, a system sour flue gas pipeline water seal liquid desorption recovery unit, its characterized in that: the recovery device comprises a container body, a water seal liquid leading-in pipe communicated with the inner cavity of the container body is arranged on the upper portion of the container body below the water seal liquid leading-in pipe, a water purification leading-out pipe communicated with the inner cavity of the container body is arranged on the upper portion of the container body, a smoke suction-removal pipe is connected to the container body to collect smoke, and a gas-liquid separation unit is arranged in a cavity region between the water seal liquid leading-in pipe and the water purification leading-out pipe.

Above-mentioned scheme is exactly to collect the SO2 water seal liquid of dissolving in the water seal liquid, by the utility model discloses carry out intensive processing with SO2 behind the gas-liquid separation, make it changing waste into valuables.

Detailed Description

The utility model provides a system acid flue gas pipeline water seal liquid desorption recovery unit includes vessel 10, the upper portion of vessel 10 is provided with the water seal liquid inlet tube 20 that communicates in the vessel 10 inner chamber, the upper portion of vessel 10 of water seal liquid inlet tube 20 below is provided with the water purification contact tube 30 that communicates in the vessel 10 inner chamber, be connected with flue gas suction pipe 40 on the vessel 10 and collect the flue gas, the cavity region between water seal liquid inlet tube 20 and the water purification contact tube 30 has arranged gas-liquid separation unit 50.

The utility model discloses can set up the position that closes on of acid making flue gas pipeline water seal, can in time give the collection processing with flue gas water seal liquid like this. In the specific scheme, one end of the water seal liquid leading-in pipe 20 is connected to the overflow part of the acid making flue gas pipeline water seal, and if the amount of the overflowed water seal liquid is large, a pumping unit can be additionally arranged between the water seal liquid leading-in pipe 20 and the acid making flue gas pipeline water seal. After the water-seal liquid inlet pipe 20 reaches the inner cavity of the container body 10, the gas-liquid separation unit 50 performs a gas-liquid separation process, the gas is collected and discharged by the flue gas suction and separation pipe 40, and the liquid is basically pure water and is recycled by the pure water outlet pipe 30, which can be reused as water-seal liquid.

Preferably, the flue gas suction and removal pipe 40 is connected with the acid making flue gas pipeline 60. By adopting the scheme, the separated SO can be separated by utilizing the negative pressure environment in the acid making flue gas pipeline 60₂Timely departing from the device, without additional air supply power, and without additional storage equipment for storing separated SO2₂But also can arrive at the acid making system in time. To overcome the SO content₂The corruption of water seal liquid to equipment, the utility model provides a including parts such as vessel 10, pipeline all can adopt corrosion-resistant material preparation, if the UPVC material can, so the intensity of vessel 10 including the tank form can not be too high, because flue gas suction takes off pipe 40 on vessel 10 links to each other with acid making flue gas pipeline 60, so for improving its security, vessel 10 even has the suction intake pipe 11, can carry out the tonifying qi to vessel 10's cavity in like this, avoided vessel 10 to work under too high negative pressure environment.

More preferably, one end of the desorption gas inlet pipe 11 is connected below the gas-liquid separation unit 50, and the other end is connected to the atmosphere. The communicating part of the desorption air inlet pipe 11 and the container body 10 is arranged below the gas-liquid separation unit 50, so that the impact of air flow can be improved, the distribution and the flow direction of water-seal liquid on the gas-liquid separation unit 50 can be disturbed, and the gas-liquid separation effect can be improved.

Preferably, the inner end of the water seal liquid inlet pipe 20 is connected to a sprinkling nozzle 21, and the sprinkling nozzle 21 sprinkles the water to the gas-liquid separation unit 50. Thus, the water seal liquid can be uniformly distributed in the gas-liquid separation unit 50, and the gas-liquid separation of the water seal liquid can be effectively carried out in time.

The gas-liquid separation unit 50 includes grid plates 51 arranged at intervals up and down, and a pall-ring-type packing 52 is accommodated between the grid plates 51. The grid plates 51 are uniformly distributed with holes, and the grid plates 51 are vertically arranged to intensively and reliably restrain the filler 52 in the space between the two grid plates 51, so that the stability of the separation effect is improved. The utility model discloses a packing 52 in to provide sufficient gas-liquid area of contact and accomplish the medium exchange, like pall ring etc. can.
