Description

Technical Field

[0001] This utility model mainly relates to the field of activated carbon adsorption technology, specifically to an activated carbon adsorption device for epoxy resin production. Background Technology

[0002] In epoxy resin production, activated carbon adsorption technology is effective in wastewater treatment and some waste gas treatment. It mainly adsorbs volatile organic compounds emitted during the epoxy resin production process. This adsorption process does not participate in the chemical reaction of epoxy resin production. It treats pollutants generated in the entire production process before they are released into the external environment. Activated carbon adsorption equipment is usually connected to the waste gas treatment pipeline in the workshop to treat volatile organic compounds in the waste gas.

[0003] Activated carbon consumables that have absorbed volatile organic compounds are classified as hazardous waste under the "National Hazardous Waste List". Therefore, the consumables in the activated carbon adsorption box need to be replaced regularly. During the waste discharge operation of activated carbon in the adsorption tower, it is usually necessary to open the waste discharge valve at the bottom of the tower to discharge the hazardous waste in the tower. In some cases, the activated carbon particles that have completed the adsorption of volatile organic compounds may stick together and form a blockage in the waste discharge pipe at the bottom of the tower, causing the waste discharge to be obstructed. At this time, workers need to use sticks to poke and tamp the waste discharge pipe.

[0004] The inventors proposed an activated carbon adsorption device for epoxy resin production. The device includes a movable component in the activated carbon stacking layer of the activated carbon adsorption tower. This component works in conjunction with a conical shelf for storing activated carbon to complete the storage or discharge of activated carbon. The movable component disperses the activated carbon on the conical shelf, preventing hazardous activated carbon waste from clogging the discharge pipe. Utility Model Content

[0005] 1. Technical problem solved by the utility model: This invention provides an activated carbon adsorption device for epoxy resin production, which solves the technical problem of blockage in the hazardous waste discharge of existing activated carbon adsorption towers.

[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: an activated carbon adsorption device for epoxy resin production, comprising a frame, wherein a plurality of vertically stacked layer tubes are fixedly disposed in the middle of the frame, wherein a bushing is welded to the inner side of the top of the layer tube to match the inner side of the bottom of the adjacent layer tube above, and a conical layer plate is detachably connected to the middle of the layer tube, wherein a sleeve is fixedly disposed in the middle of the conical layer plate.

[0007] Furthermore, multiple working shelves are vertically distributed and fixed on the right side of the frame. A tower top and a tower bottom are fixed on the top and bottom of the frame, respectively. An air inlet pipe is fixed in the middle of the tower top. The top of the tower bottom is detachably connected to the bottom of the shelf pipe. An exhaust pipe is fixed on the outside of the tower bottom. A waste discharge pipe is fixed on the bottom of the tower bottom. A waste discharge butterfly valve is fixed on the bottom of the waste discharge pipe.

[0008] Furthermore, a sampling tube and a discharge tube are respectively fixed on the right side of the layer tube, and the tops and bottoms of multiple adjacent layer tubes abut against each other in sequence.

[0009] The multiple stacked structures of the tubes can be changed into a single integrated structure according to actual procurement needs.

[0010] Furthermore, the conical layer has a downwardly concave conical structure, and multiple air holes are formed on the surface of the conical layer.

[0011] The recommended range for the semi-cone angle of the tapered shelf is 65°-80°.

[0012] Furthermore, a sealing tube is movably connected to the middle of the sleeve, and an installation ring is detachably connected to the outside of the sealing tube. Multiple clamping plates are fixed to the outside of the installation ring, and multiple dispersing rings of different diameters are fixed to the outside of the clamping plates.

[0013] Dispersion rings of different diameters are staggered above the conical plate to ensure that the activated carbon adsorption layer above the conical plate can be disturbed and dispersed during their up-and-down movement.

[0014] A sealing gasket must also be installed between the sleeve and the plugging tube to prevent particles inside the tower from entering and affecting the closure.

[0015] Furthermore, the middle portions of the plurality of sealing tubes are respectively fixed to the top to the middle of the connecting rod, the bottom of the connecting rod is fixedly connected to the top output end of the lifting cylinder, the lifting cylinder is disposed on the bottom outside of the waste discharge pipe, and the output end portion of the lifting cylinder is movably sleeved with the middle portion of the waste discharge pipe.

[0016] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model provides an activated carbon adsorption device for epoxy resin production. The sealing pipe can drive the clamping plate and the dispersing ring to move up and down above the conical plate through the installation ring. During the up and down movement of the dispersing ring and the clamping plate, the activated carbon adsorption layer above the conical plate can be disturbed and dispersed to avoid the activated carbon adsorption layer from clumping and causing subsequent waste discharge to be obstructed. This effectively improves the waste discharge efficiency of the activated carbon adsorption tower and eliminates the need for workers to use sticks to poke and tamp at the waste discharge pipe. The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0022] See attached document Figure 1-5 This utility model provides an activated carbon adsorption device for epoxy resin production, including a frame 1. A plurality of vertically stacked tubes 2 are fixed in the middle of the frame 1. A bushing 21 that matches the inner bottom of the adjacent tube 2 is welded to the inner side of the top. A conical plate 3 is detachably connected to the middle of the tube 2. A sleeve 31 is fixed in the middle of the conical plate 3.

[0023] In this embodiment, multiple working shelves 11 are vertically distributed and fixed on the right side of the frame 1. The top and bottom of the frame 1 are respectively fixed with a tower top 5 and a tower bottom 6. An air inlet pipe 51 is fixed in the middle of the tower top 5. The top of the tower bottom 6 is detachably connected to the bottom of the shelf pipe 2. An exhaust pipe 61 is fixed on the outside of the tower bottom 6. A waste discharge pipe 62 is fixed on the bottom of the tower bottom 6. A waste discharge butterfly valve 63 is fixed on the bottom of the waste discharge pipe 62.

[0024] The working plate 11 is set up to facilitate workers to carry out maintenance work on the outside of the tower top 5 and the layer tube 2. The activated carbon adsorption layer that is densely stacked on the conical plate 3 can be sampled through the sampling tube 22, and the activated carbon particles can be densely stacked on the conical plate 3 through the discharge tube 23.

[0025] The inlet pipe 51 is located at the top of the tower 5, and the exhaust pipe 61 is located at the bottom of the tower 6. This allows the exhaust gas to pass through the activated carbon adsorption layer and pores 32 on the conical plate 3 from top to bottom. The direction of gas flow is consistent with the direction of gravity stacking of activated carbon particles, ensuring that the activated carbon particles form a dense activated carbon adsorption layer and guaranteeing the stability of the stacking structure of the activated carbon adsorption layer on the conical plate 3. Compared with the disturbance to the activated carbon layer caused by the upward blowing of exhaust gas, the top-down gas path design of this application can minimize the friction and collision between activated carbon particles, effectively improving the problem of activated carbon particles breaking due to disturbance between particles during the adsorption stage, which affects the adsorption efficiency.

[0026] In this embodiment, a sampling tube 22 and a discharge tube 23 are fixedly installed on the right side of the layer tube 2, and the tops and bottoms of multiple adjacent layer tubes 2 abut against each other in sequence.

[0027] Multiple tube layers 2 are stacked together by a bushing 21. The bushing 21 is designed to allow the top of the tower 5 to be stacked with the tube layers 2.

[0028] In this embodiment, the conical layer 3 has a concave conical structure, and multiple air holes 32 are opened on the surface of the conical layer 3.

[0029] The design of the vent 32 of the conical plate 3 completes the top-to-bottom gas path design between the top of the tower 5, the tube 2 and the bottom of the tower 6.

[0030] The conical plate 3 adopts a concave conical structure design. With the cooperation of the lifting cylinder 45 and the connecting rod 44, the sealing pipe 4 and the sleeve 31 are misaligned, which can reverse the activated carbon particles piled on the surface of the conical plate 3 to the bottom of the tower 6. Then, they are discharged to the outside of the equipment through the waste discharge pipe 62 and the waste discharge butterfly valve 63, and the activated carbon hazardous waste is recycled and treated by the workers in accordance with the hazardous waste treatment requirements.

[0031] In this embodiment, a sealing tube 4 is movably connected to the middle of the sleeve 31, and an installation ring 41 is detachably connected to the outside of the sealing tube 4. Multiple clamping plates 42 are fixedly provided on the outside of the installation ring 41, and multiple dispersing rings 43 of different diameters are fixedly provided on the outside of the clamping plates 42. The middle parts of the multiple sealing tubes 4 are respectively fixed to the top to the middle of the connecting rod 44. The bottom of the connecting rod 44 is fixedly connected to the top output end of the lifting cylinder 45. The lifting cylinder 45 is located on the bottom outside of the waste discharge pipe 62, and the output end of the lifting cylinder 45 is movably sleeved with the middle of the waste discharge pipe 62.

[0032] The lifting cylinder 45 and the connecting rod 44 work together to change the working position of the sealing tube 4 in the middle of the sleeve 31. The sealing tube 4 and the sleeve 31 work together to complete the sealing treatment in the middle of the conical plate 3 and complete the dense stacking treatment of activated carbon particles above the conical plate 3.

[0033] The sealing pipe 4, through the installation ring 41, can drive the clamping plate 42 and the dispersing ring 43 to move up and down above the conical plate 3. During the up and down movement of the dispersing ring 43 and the clamping plate 42, the activated carbon adsorption layer above the conical plate 3 can be disturbed and dispersed, avoiding the agglomeration of the activated carbon adsorption layer and preventing subsequent waste discharge from being blocked. This effectively improves the waste discharge efficiency of the activated carbon adsorption tower, eliminating the need for workers to use sticks to poke and tamp at the waste discharge pipe 62.

[0034] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
