The supporting pad 11 is used for supporting the base 1.

[0026] A drain pipe 16 is fixedly connected with a drain valve (not shown in the figure) inside. The drain valve is a prior art. The drain valve is used for preventing the steam from entering and the condensed water from flowing into the inside.

[0027] A plurality of quartz sand bodies (not shown in the figure) are arranged in the filter screen box 19. The quartz sand bodies are used for filtering the steam. A rotating shaft (not shown in the figure) is fixedly installed at both ends of the filter screen box 19. The filter screen box 19 is connected with the fixed seat 17 through a bearing.

[0028] A driving member 18 is fixedly installed on the outer side of the fixed seat 17. The driving member 18 can be a motor. The output end of the driving member 18 is fixedly connected with a group of rotating shafts. The driving member 18 is suitable for starting to drive the rotating shafts to rotate, thereby driving the filter screen box 19 to rotate.

[0029] An air outlet cover 115 is arranged at the upper end of the fixed seat 17. The air outlet cover 115 is arranged in a penetrating manner. A plurality of water flow protrusions 113 are fixedly installed on the inclined plate 112. The water flow protrusions 113 make the impurities in the condensed water adhere to the upper side. A liquid return pipe (not shown in the figure) is fixedly and communicatively installed on the fixed seat 17. The liquid return pipe is communicated with the liquid return box 15.

[0030] Three groups of filter assemblies 2 are arranged in the liquid return box 15. The three groups of filter assemblies 2 are arranged from top to bottom. The filter assembly 2 comprises two groups of guide rails 21 fixedly installed on the inner walls of the liquid return box 15. A sliding block 22 is slidingly installed on the guide rail 21. The sliding block 22 can move along the straight line direction of the guide rail 21.

[0031] A placing rack 23 is fixedly installed between the two groups of sliding blocks 22. The placing rack 23 is arranged in a penetrating manner. A support step 24 is fixedly installed on the inner wall of the placing rack 23. An adsorption net 26 is placed on the support step 24. It should be noted that the adsorption nets 26 on the three groups of filter assemblies 2 are arranged from top to bottom as a quartz sand adsorption net, a first activated carbon adsorption net, and a second activated carbon adsorption net.

[0032] A sealing part (not shown in the figure) is fixedly installed at one end of the placing rack 23, and a slot 114 adapted to the sealing part is formed on the reflux box 15. A connecting unit is installed on the side of the placing rack 23, which is a lock catch in the prior art, and the connecting unit comprises a fixed plate 27 fixedly installed on the side of the placing rack 23, a mounting seat 28 fixedly installed on the fixed plate 27, a hinged rod 29 movably installed on the mounting seat 28, and a clamping rod 211 movably installed on the hinged rod 29. A hook block 212 adapted to the clamping rod 211 is fixedly installed on the sealing part.

[0033] A handle 210 is fixedly installed on the hinged rod 29, which facilitates the rotation of the hinged rod 29. When the placing rack 23 is inserted into the reflux box 15 through the two sets of sliding blocks 22, the sealing part is sealed with the slot 114. At this time, the handle 210 is held and the hinged rod 29 is rotated to make the clamping rod 211 move out of the hook block 212, so that the placing rack 23 is separated from the reflux box 15.

[0034] A water outlet slope (not shown in the figure) is arranged at the lower end of the adsorption net 26 at the lowermost end, and the water outlet slope is fixedly connected to the inner wall bottom end of the reflux box 15. A reflux pipe 111 is arranged at the left end of the water outlet slope, and the reflux pipe 111 is used for flowing the condensed water into the inside of the steam stove 12 again, and the reflux pipe 111 is communicated with the steam stove 12.

[0035] The tail gas enters the filter screen box 19 inside the fixed seat 17 from the gas inlet pipe. A plurality of quartz sand bodies (not shown in the figure) arranged in the filter screen box 19 filter the steam and remove the impurities therein. Meanwhile, the driving part 18 (which can be a motor) installed on the outside of the fixed seat 17 is started, and the output end thereof drives the rotating shaft fixedly connected thereto to rotate, thereby making the filter screen box 19 connected to the fixed seat 17 through the bearing connected to the rotating shaft to rotate, and further enhancing the filtering effect, so that the impurities can be more fully trapped.

[0036] A plurality of water flow blocks 113 are fixedly installed on the inclined plate 112 arranged at the lower end of the filter screen box 19. When the condensed water appears, the impurities inside the condensed water will be attached to the water flow blocks 113, thereby further separating the impurities.

[0037] The condensed water flowing into the reflux box 15 will be further filtered by the three sets of filtering assemblies 2 in sequence. The three sets of filtering assemblies 2 are arranged in sequence from top to bottom. In each filtering assembly 2, the placing rack 23 can be inserted into the reflux box 15 by moving along the guide rail 21 in a straight line through the two sets of sliding blocks 22. The support steps 24 on the inner wall of the placing rack 23 are arranged with the adsorption nets 26. The adsorption nets 26 on the three sets of filtering assemblies 2 are arranged in sequence from top to bottom as a quartz sand adsorption net, a first activated carbon adsorption net, and a second activated carbon adsorption net. The different adsorption nets are used for layer-by-layer adsorption and filtration of the impurities and the like remaining in the condensed water.

[0038] The sealing part at one end of the placing rack 23 is sealed with the insertion slot 114 on the reflux box 15, and is fixed through the connecting unit. The cooperation or separation of the buckling rod 211 and the hook block 212 is realized by rotating the articulated rod 29 through the handle 210, so that the placing rack 23 is conveniently installed and disassembled, and the adsorption net 26 is conveniently replaced and maintained.

[0039] The condensed water filtered through the above layers flows along the water outlet slope at the lower end of the adsorption net 26 at the lowermost end, and finally flows into the inside of the steam furnace 12 through the reflux pipe 111 to be recycled, so that the condensed liquid in the tail gas treatment is effectively recovered and reused.

[0040] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
