[0031] Embodiment 2

[0032] Referring to Figures 1-7 In other parts are the same as embodiment 1, the embodiment is different from embodiment 1 in that:

[0033] The inner bottom surface of the heat preservation barrel 1 is in the shape of an inverted cone, which is coaxial with the filter cylinder 5. The inner bottom surface of the heat preservation barrel 1 is provided with a multipurpose assembly, which includes a linkage plate 13, a magnetic plate 14, a linkage frame 15, and a speed reduction gear set 16. The speed reduction gear set 16 is installed on the rod body of the conveying shaft 7 between the filter cylinder 5 and the motor 9. The lower end of the linkage frame 15 is connected with the speed reduction gear set 16. The magnetic plate 14 is installed on the upper end of the linkage frame 15. The linkage plate 13 is placed on the inner bottom surface of the heat preservation barrel 1. The linkage plate 13 and the magnetic plate 14 are separated by the body wall of the heat preservation barrel 1. Due to the conical shape of the inner bottom surface of the heat preservation barrel 1, the particulate matter mixed in the hot gas flowing into the heat pipe 2 can conveniently move along the conical surface to the inlet 6 of the filter cylinder 5, thereby facilitating the conveying of the deposited particulate matter by the conveying shaft 7. The speed reduction gear set 16 is an existing planetary gear set or a turbine worm, which has a speed reduction transmission effect. In this scheme, it will not be described in detail. The specific type and speed reduction ratio can be selected according to the specific use requirements. The setting of the multipurpose assembly enables the magnetic plate 14 to rotate through the speed reduction gear set 16 when the conveying shaft 7 rotates. The magnetic plate 14 drives the linkage plate 13 to rotate synchronously through the body wall of the heat preservation barrel 1 (the thickness of the body wall is set according to the magnetic attraction performance). That is, the linkage plate 13 rotates around the filter cylinder 5 while adhering to the inner bottom surface of the heat preservation barrel 1. Thus, through the rotation of the linkage plate 13, the movement of the deposited particulate matter to the filter cylinder 5 is accelerated, and the liquid inside the heat preservation barrel 1 is stirred to a certain extent, so that the temperature inside the heat preservation barrel 1 is relatively uniform, thereby avoiding the phenomenon of low water temperature at the heat exchange pipe 4.

[0034] The upper end of the rotating shaft 12 extends above the mounting shell 10 and is provided with a rotating handle. The upper surface of the mounting shell 10 and the side away from the shunt pipe 8 are provided with a material taking hole and a sealing cover. The heat pipe 2 and the cold pipe 3 are respectively arranged at the lower end and the upper end of the heat preservation barrel 1. The pipe body of the cold pipe 3 is provided with a temperature measurer. The collecting cylinder 17 is arranged in the collecting bin of the transposition disc 11. The filter cylinder 5 is provided with a filter hole on the cylinder body at the upper end inside the heat preservation barrel 1. The circulating assembly includes an inlet pipe, an outlet pipe, and a pump 18. One end of each of the inlet pipe and the outlet pipe is connected with the heat exchange pipe 4. The pump 18 is installed on the pipe body of the inlet pipe. The setting of the rotating handle facilitates the rotation of the transposition disc 11 driven by the rotating shaft 12, thereby facilitating the cleaning of the collected particulate matter. The setting of the collecting cylinder 17 facilitates the collection of the particulate matter flowing out of the shunt pipe 8, thereby enabling the subsequent personnel to directly replace the collecting cylinder 17, i.e., improving the cleaning efficiency of the personnel cleaning the particulate matter inside the collecting bin.

[0035] Principle and advantages: in the use process, the external boiler tail gas is introduced into the heat preservation barrel 1 through the heat pipe 2, the heat preservation barrel 1 is filled with liquid, and the liquid level is two-thirds of the height of the heat preservation barrel 1, that is, the liquid surface of the liquid in the heat preservation barrel 1 is separated from the top of the heat preservation barrel 1, at this time, the high-temperature tail gas mixed with particulate impurities enters the lower part of the heat preservation barrel 1, that is, the high-temperature gas exchanges heat with the liquid in the heat preservation barrel 1 and gradually rises, and finally is discharged through the cold pipe 3, and the cold pipe 3 is a condensing pipe for condensing and recycling water vapor, in this process, the liquid in the heat preservation barrel 1 is continuously heated with the entering of the boiler tail gas, and the particulate in the tail gas is gradually deposited on the inner bottom surface of the heat preservation barrel 1, at the same time, the heat exchange pipe 4 is connected with the external heat utilization facilities through the circulating assembly, such as water bath, object heat preservation, object heating, heating and the like, that is, under the action of the pump 18, the low-temperature liquid enters the heat exchange pipe 4 through the liquid inlet pipe, and finally flows out through the liquid outlet pipe, and in this process, the liquid exchanges heat with the heat in the heat preservation barrel 1 through the heat exchange pipe 4 to absorb heat and increase temperature, so that the heat in the heat preservation barrel 1 is replaced and discharged.

[0036] Further in the above process, the particulate deposited on the inner bottom surface of the heat preservation barrel 1 is transported to the upper end of the filter cylinder 5 by the conveying shaft 7, and during the conveying process of the particulate, the particulate is continuously drained when it is separated from the liquid in the heat preservation barrel 1 with the increase of height, finally the particulate flows into the collection bin of the transposition disc 11 through the shunt pipe 8 at the top of the filter cylinder 5, and because the collection bin is provided with a plurality of collection bins, when one of the collection bins is full, the empty collection bin can be quickly moved to the lower end of the shunt pipe 8 to continue the subsequent collection by rotating the transposition disc 11, and the full collection bin is moved to the material taking hole of the mounting shell 10 for cleaning.

[0037] In summary, in the use of the present application, by filling the heat preservation barrel 1 with liquid, the heat in the boiler tail gas can be effectively recovered, and the particulate in the tail gas can be precipitated and filtered, and the filtered particulate can be conveniently transported to the collection bin of the transposition disc 11 under the driving of the conveying shaft 7, at this time, only the transposition disc 11 needs to be rotated to make the device still normally filter and collect the particulate when the personnel clean the filtered particulate, that is, the device does not need to be stopped, thereby making the present application compared with the traditional scheme, the present application does not need to be stopped to clean the filtered particulate, thereby improving the working efficiency of the device to a certain extent.

[0038] It is further pointed out that the heat pipe 2 is bent upwards away from the heat preservation barrel 1, and the pipe body of the heat pipe 2 can be provided with an air pump or other pressurizing components, so as to pump the boiler tail gas into the heat preservation barrel 1. The arrangement of the multipurpose assembly enables the magnetic plate 14 to rotate through the reduction gear set 16 when the conveying shaft 7 rotates, and the magnetic plate 14 drives the linkage plate 13 to rotate synchronously through the body wall of the heat preservation barrel 1 (the thickness of the body wall is set according to the magnetic attraction performance). The linkage plate 13 rotates around the filter cylinder 5 along the inner bottom surface of the heat preservation barrel 1. Through the rotation of the linkage plate 13, the particles in the sediment can be moved to the filter cylinder 5, and the liquid in the heat preservation barrel 1 can be stirred to a certain extent, so that the temperature in the heat preservation barrel 1 is uniform, and the phenomenon of low water temperature at the heat exchange pipe 4 is avoided. The arrangement of the rotating handle facilitates the rotation of the displacement disc 11 through the rotating shaft 12, so as to facilitate the cleaning of the collected particles. The arrangement of the collection cylinder 17 facilitates the collection of the particles flowing out of the shunt pipe 8, so that the subsequent personnel can directly replace the collection cylinder 17, that is, the cleaning efficiency of the personnel for cleaning the particles in the collection bin is improved.

[0039] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
