[0029] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the specific protection scope requested by the utility model.

[0030] As Figures 1-6 shown, a condensing hydrochloric acid recovery treatment device, including processing tank 1, the bottom of processing tank 1 is fixedly connected with liquid outlet pipe 4, the inside of processing tank 1 is fixedly connected with partition 7;

[0031] The top of processing tank 1 is fixedly connected with air inlet pipe 2 through condensing mechanism 5, the middle part of air inlet pipe 2 is provided with pre-processing mechanism 3, and the bottom of pre-processing mechanism 3 is fixedly installed with collection box 6;

[0032] Pre-processing mechanism 3 includes shell 31, filter plate 35 and anti-blocking assembly 36, rotating shaft 33 is rotatably installed in the inside of shell 31 through support column 32, and turbine blade 34 is fixedly connected to the outside of rotating shaft 33.

[0033] Anti-blocking assembly 36 includes cleaning brush roller 361 and spring 362, spring 362 is abutted on one side of cleaning brush roller 361, and baffle 363 is fixedly installed on the surface of rotating shaft 33.

[0034] See attached document Figure 1 and Figure 5 In this embodiment, two vertically evenly arranged partitions 7 inside the processing tank 1 are used to separate the processing tank 1 to form a multi-stage cooling water chamber.

[0035] In the above embodiment, the interior of the treatment tank 1 can be divided into multiple cooling water chambers with decreasing temperatures by the partition 7. The multi-stage cooling water chambers can cooperate with the condensation mechanism 5 to make the hydrochloric acid waste gas condensation efficiency better and the condensation effect better.

[0037] In the above embodiment, the filter plate 35 filters the impurities contained in the hydrochloric acid waste gas as it passes through the housing 31, thereby preventing the waste gas from carrying impurities into the condensation mechanism 5 and causing blockage of the condensation mechanism 5, and further preventing the hydrochloric acid recovery liquid from containing impurities.

[0038] Furthermore, a turbine blade 34 is welded to the surface of the rotating shaft 33, and a cleaning brush roller 361 is provided on one side of the filter plate 35. Therefore, when the exhaust equipment sends hydrochloric acid waste gas into the air inlet pipe 2, the waste gas can drive the rotating shaft 33 and the cleaning brush roller 361 to rotate after passing through the turbine blade 34.

[0039] Furthermore, a slider is installed inside the cleaning brush roller 361, and a groove is provided on the surface of the rotating shaft 33, so that the cleaning brush roller 361 can be slidably mounted on the surface of the rotating shaft 33.

[0042] The working principle of the utility model is: through using the air extraction equipment, the waste gas containing hydrochloric acid steam is sent into the air inlet pipe 2, the waste gas enters the pretreatment mechanism 3 through the air inlet pipe 2, when the waste gas passes through the turbine blade 34, can push its rotation, and drive the rotating shaft 33 and the clean brush roller 361 synchronous rotation, and at this time, the waste gas passes through the filter plate 35 and filters the impurities and enters the condensing mechanism 5 through the connecting pipe 51, at this time, since the clean brush roller 361 and the spring 362 make the impurities attached to the surface of the filter plate 35 clean to prevent blockage, the clean hydrochloric acid waste gas entering the connecting pipe 51 is sent into a plurality of condensing pipes 54 through the shunt pipe 52 and the connecting piece 53 respectively, and the condensing pipe 54 is installed in the inside of the treatment tank 1 through the partition plate 7, and the inside of the treatment tank 1 is divided into a plurality of cooling water cavities with decreasing temperature by the partition plate 7, so that the hydrochloric acid waste gas can be accelerated to condense into hydrochloric acid liquid, and then sent into the collecting tank through the liquid outlet pipe 4.

[0043] The above only is the preferred embodiment of the utility model, it should be pointed out that, for ordinary technical personnel in the prior art, under the premise of not departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be regarded as the protection scope of the utility model.
