A water-cooled circulation device for hazardous waste incineration flue gas

Abstract

The invention discloses a water-cooling circulation device, which includes a cooling device, a circulation device, a first deacidification tower, and a second deacidification tower. The side of the first deacidification tower is fastened to the side of the second deacidification tower through a flue gas pipeline. The first deacidification tower and the second deacidification tower are connected to the circulation device through water pipes, the circulation device and cooling device are connected through water pipes, the cooling device is firmly connected to the first deacidification tower, the cooling device includes a water tank and a distribution ring, and the distribution ring is set There is a distribution ring groove, and there are several ring groove outlets at the bottom of the distribution ring groove. The first deacidification tower includes a tower body, and a water inlet hole is provided on the top of the tower body. The bottom of the pool extends upwards and is fixedly connected with two support plates, and the upper end of the circulation pool extends downwards and is fixedly connected with two partitions. The support plates and partitions are arranged at intervals, and the upper ends of the support plates are respectively fixedly connected with the sides of the primary evaporation platform and the secondary evaporation platform .

Description

technical field [0001] The invention relates to the technical field of flue gas water cooling cycle, in particular to a hazardous waste incineration flue gas water cooling cycle device. Background technique [0002] The hazardous waste incineration system is equipped with a deacidification tower after the dust collector. The material of the deacidification tower is generally FRP. The normal temperature of domestic FRP does not exceed 150°C. The flue gas at the outlet of the dust collector is usually between 160-180°C. When entering the FRP deacidification tower, it will exceed the tolerance temperature of FRP, which will cause the deacidification tower to soften and deform, and even cause a safety accident that the deacidification tower collapses. For this reason, it is necessary to cool down the flue gas before it enters the FRP deacidification tower. Usually, water spraying is used to cool down. Since the water spraying cooling in this area coincides with the low-temperatu...

Problems solved by technology

There is a large amount of salt in the circulating lye, which will cause serious salt corrosion during heat exchange. At the same time, salt blockage will occur. After a period of operation, the furnace needs to be shut down for cleaning, which cannot guarantee the continuous operation of the equipment. In addition, the use of heat exchangers Very short lifespan, requiring replacement in a few months
