Efficient evaporation device and system for salt-containing organic wastewater

Abstract

The invention discloses an efficient evaporation device and system for salt-containing organic wastewater. The system comprises an efficient evaporation device body, a gas-liquid heat exchange deviceand an advanced treatment device, wherein the efficient evaporation device is a submerged combustion evaporator, a combustor, a demister and a smoke outlet are mounted at the top of the evaporator, amanhole, a liquid level meter, a valve pipeline and the like are mounted on the side surface, a drain valve, a salt mud well, a hand hole and a screw pump are arranged at the bottom, and a combustionchamber, a baffle plate, a circulating baffle, a submerged pipe, an injection nozzle and the like are mounted inside; the gas-liquid heat exchange device comprises a tubular gas-liquid heat exchangerand a gas-liquid separation chamber; the advanced treatment device comprises an NF / RO film and a PT absorption tower. The injection nozzle is used for distributing gas, so that the heat transfer efficiency between flue gas and evaporation liquid is improved, and the liquid phase circulation in the evaporator is enhanced; mud-water separation is achieved through the salt mud well, and the risk of pipeline blockage is reduced; a baffle plate is mounted at the upper part of the evaporation chamber, so that the height of the evaporation chamber is reduced while gas-liquid separation is enhanced; the gas-liquid heat exchanger is beneficial to evaporation heat recovery and condensate water recycling; and the advanced treatment device ensures that the discharged smoke and the discharged water reach the standard and are discharged. The device has the advantages of strong anti-blocking capability, high energy utilization efficiency, low pollutant discharge and the like, and can be widely applied to the field of high-salt organic wastewater treatment.

Description
