Problems solved by technology

[0002] In recent years, the country has become more and more strict on environmental protection in order to control smog. Many garbage and hazardous waste incineration projects require that no white smoke can appear in the chimney. In the traditional hazardous waste incineration flue gas wet dewhitening process, steam is added after the scrubber The heater is used to solve the above problems, but it can only meet the white smoke removal effect in high temperature weather in summer, and in winter, because the temperature is too low, the smoke after passing through the steam heater is mixed with the outside air and then condenses, and the chimney will still condense. White smoke appears. In addition, the temperature of the flue gas from the dust collector drops below the acid dew point after being washed by the scrubber, and then the low-temperature flue gas enters the steam heater. Since the flue gas is low-temperature and contains acidic gas, it is easy to corrode the steam The heater and subsequent equipment have a short service life, and the steam consumption is relatively large during the whitening process

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0018] Such as figure 1 As shown, a hazardous waste incineration wet deacidification flue gas dewhitening system of the present invention includes a washing tower, a steam heater 6, and the steam heater 6 is connected to the chimney 7, and it also includes the flue gas connected to the bag filter. The fume-smoke heat exchanger 5 is connected with the steam heater 6 after being circulated with the washing tower; specifically, the fume-smoke heat exchanger 5 is a GGH fume-smoke heat exchanger, and its heat exchange The pipe material is PTFE fluoroplastic; the steam heater 6 is a SGH steam heater.

[0019] The scrubber includes a primary scrubber 1 and a secondary scrubber 2. The smoke heat exchanger 5 is connected to the steam heater 6 after sequentially circulating with the primary scrubber 1 and the secondary scrubber 2. The primary scrubber 1. The secondar...
