Problems solved by technology

However, the prior art has the following major problems: only the flue gas entering the spray tower is used to evaporate and concentrate the waste water. Since the flue gas velocity in the spray tower has a certain limit, generally not greater than 4 m / s, the flue gas Excessive flow rate will increase the carrying of the waste water by the flue gas, thus limiting the flow rate of the flue gas entering the spray tower, thereby limiting the evaporation and concentration of the waste water in the spray tower
This method only uses the mixed heat exchange of waste water and flue gas for evaporation and concentration, so when the evaporation amount is constant, the required amount of flue gas is relatively large

The waste water concentration device has the characteristics of good concentration effect, low cost and high evaporation efficiency.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a waste water concentration device which utilizes waste heat of flue gas to concentrate waste water. Background technique [0002] At present, the devices on the market that use boiler flue gas to evaporate and concentrate waste water generally adopt a spray tower structure, which usually includes a cylindrical tower body, a tower pool at the bottom of the tower body, and an inlet tank corresponding to the upper part of the tower body. There is an air outlet on the top of the tower body, a spray pipe is arranged in the middle of the tower body corresponding to the air inlet and the air outlet, and a nozzle is arranged on the spray pipe, and there is also a connection between the tower pool and the spray pipe on the outside of the tower body. The conduit is provided with a circulating pump. The waste water is sprayed down from the spray pipe, and underg...
