Abstract

The invention provides a boiler flue gas and wastewater comprehensive purification device / method and a water tank structure. The device comprises a boiler flue gas conveying channel part and a purification water pool part. Specifically, the boiler flue gas conveying channel part includes a flue gas channel and a boiler flue gas fan; and the purification water pool part includes a water tank, partition plates, a water pump, and nozzles. The water tank comprises a water inlet, a water outlet, a flue gas inlet and a flue gas outlet. The flue gas channel is connected to the flue gas inlet of the water tank, the flue gas outlet is connected to a chimney, the water pump is connected to the water tank and the nozzles, and the partition plates and the nozzles are disposed in the water tank. Silkworm cocoon reeling wastewater and boiler flue gas can reach mutual purification. At the same time, heat of the boiler flue gas is utilized to pre-heat the water flowing into the boiler. The device and the method provided by the invention can reach an ideal purification effect on boiler flue gas and silkworm cocoon reeling wastewater, and can reduce the cost by over 50%.

Description

technical field [0001] The application relates to treatment of boiler flue gas and waste water (especially cocoon reeling waste water), in particular to a comprehensive purification device and method for boiler flue gas and waste water and a water tank structure. Background technique [0002] Silk is usually steamed to remove sericin (silk reeling). Silk processing factories (silk reeling factories, silk quilt factories) will use fresh water to cook silk and produce sewage (cocoon reeling wastewater), which contains a lot of organic matter. If it is discharged directly, it will pollute the environment, so it needs to be treated before discharge. [0003] Boilers are used to heat water during the reeling process. Dust (including fly ash and carbon black), sulfur and nitrogen oxides contained in boiler flue gas are all substances that pollute the atmosphere, and their emission indicators can reach several to dozens of times the environmental protection regulations without pur...
