Alkali washing absorption oil cooler

Abstract

The utility model discloses an alkali-washed absorption oil cooler, which relates to the technical field of coolers and comprises a cooling box and a heat exchange component. The cooling box is connected with an absorption oil inlet pipe and an absorption oil outlet pipe, and the heat exchange component comprises a liquid inlet main pipeline. When the absorption oil moves from the absorption oil inlet pipe to the bottom of the cooling box, the absorption oil will flow through a filter screen and the outside of the heat exchange tube, and the filter screen plays a filtering role on the absorption oil. After the absorption oil flows through the outside of the heat exchange tube for a long time, impurities and stains will accumulate on the outside of the heat exchange tube, affecting the heat exchange between the heat exchange tube and the absorption oil. Therefore, a pull rod is pulled at regular intervals to cause a sliding frame to slide, and the sliding of the sliding frame can enable a cleaning ring to clean the heat exchange tube. At this time, the filter screen can still filter the absorption oil. At this time, on the one hand, the absorption oil can be decontaminated to improve the role played in the absorption oil alkali-washing system, and on the other hand, impurities can be prevented from accumulating on the heat exchange tube for a long time, affecting the heat exchange efficiency.

Description

Technical Field

[0001] The utility model relates to the technical field of coolers, in particular to an alkali washing absorption oil cooler. Background Art

[0002] In the alkali washing system, an evaporative cooler or cooling tower is usually used to reduce the temperature of the alkali washing liquid. This cooler can effectively reduce the temperature of the alkali washing liquid to ensure that the system can operate normally and improve production efficiency.

[0003] The patent with publication number CN205192286U discloses an evaporative cooler, which includes a fan, a water collector, a water spray nozzle, a heat exchanger tube bundle and a water receiving tray arranged in sequence from top to bottom, and a main shutter air inlet installed on the lower side of the cooler box body. The heat exchanger tube bundle is arranged in a folded shape, and a metal mesh is fixed between the upper and lower groups of horizontally arranged heat exchanger tube bundles. The metal mesh is composed of more than two layers of metal mesh stacked together. The multi-layer metal mesh has the characteristics of porosity and can contain a large amount of water. Even if the wind speed is high, it is not easy to blow away the spray water. According to the fluid mechanics seepage theory in porous media, the capillary force generated by the metal mesh can distribute the contained water more evenly. Even if the water dripping from the upper heat exchange tube is unevenly distributed, it can flow out evenly from the bottom of the entire metal mesh after passing through the metal mesh, avoiding local water shortage and drying on the heat exchange tube.

[0004] The prior art such as that in the above-mentioned patent can cool the alkaline washing absorption oil sprayed in the cooling box by injecting cooling water into the serpentine pipe. The alkaline washing absorption oil will produce some impurities in the alkaline washing system process. On the one hand, these impurities will affect the effect of the absorption oil in the alkaline washing system. On the other hand, the impurities are adsorbed and accumulated on the cooling pipe of the cooler, which will affect the cooling effect of the cooler on the absorption oil. Utility Model Content

[0005] The utility model aims to provide an alkali-washing absorption oil cooler to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an alkaline washed absorption oil cooler, comprising a cooling box and a heat exchange component, the cooling box is connected with an absorption oil inlet pipe and an absorption oil outlet pipe, the heat exchange component comprises a liquid inlet main pipeline, a liquid outlet main pipeline and a plurality of heat exchange tubes, each heat exchange tube is located in the cooling box, and one end of each heat exchange tube is connected with the liquid inlet main pipeline, and the other end is connected with the liquid outlet main pipeline; it also includes two sliding frames inserted together and at least one sliding frame is fixedly connected with a pull rod, the two sliding frames are vertically slidably connected in the cooling box, filter screens are respectively arranged in the two sliding frames, and a plurality of one-to-one corresponding semicircular rings are respectively opened on the opposite sides of the two sliding frames, each corresponding two semicircular rings can be combined to form a circular cleaning ring, and each cleaning ring is slidably sleeved and connected with each heat exchange tube in a one-to-one manner; the pull rod vertically passes through the top of the cooling box.

[0007] Furthermore, a spray assembly is provided on one end of the absorption oil inlet pipe located in the cooling box, the spray assembly includes a transverse pipe and a plurality of spray nozzles distributed transversely in parallel, the transverse pipe is connected with the absorption oil inlet pipe, each spray nozzle is connected with the transverse pipe, each spray nozzle is used to spray the absorption oil onto the heat exchange tube, the absorption oil flows from the absorption oil inlet pipe to the transverse pipe, and is then sprayed out by the spray nozzles on the transverse pipe, and the spray nozzles are directed toward the heat exchange tubes close to the liquid inlet main pipe, and the absorption oil is sprayed onto the heat exchange tubes through the spray nozzles, so that the absorption oil can contact the heat exchange tubes earlier for cooling, and the spray nozzles spray the absorption oil to increase the contact area between the absorption oil and the heat exchange tubes, thereby effectively improving the heat exchange efficiency.

[0008] Furthermore, a rubber half ring is arranged in each semicircular ring. When the semicircular ring is used to clean the heat exchange tube, the rubber half ring is used to prevent the absorbed oil from flowing through the gap between the two semicircular rings, and also to prevent the absorbed oil from flowing through the gap between the semicircular ring and the heat exchange tube, thereby indirectly improving the filtering quality.

[0009] Furthermore, a filter frame is fixedly connected to the filter screen on all sides, and the filter screen is inserted into the corresponding sliding frame through the filter frame. When the filter screen is replaced, it is only necessary to slide the filter frame out of the sliding frame and replace the new filter screen and the new filter frame.

[0010] Furthermore, side windows are provided on the opposite sides of the cooling box, and sealing plates capable of closing the corresponding side windows are detachably connected to the windows on both sides. The filter is in a constant working state and needs to be replaced regularly. In addition, the semi-circular ring scrapes the heat exchange tube, so the wear of the semi-circular ring is also large and needs to be replaced regularly. Therefore, when the filter or the semi-circular ring needs to be replaced, the sealing plate is opened to expose the side window to the outside, and the internal filter and filter frame are taken out from the side window, or the filter frame is taken out first and then the sliding frame is taken out to replace the filter or the semi-circular ring. It is worth mentioning that the vertical opening height of the side window here is greater than the thickness of the sliding frame, which will be convenient for the worker to replace it.

[0011] Furthermore, there are two pull rods, which are screwed to the two sliding frames one by one. A handle is provided between the ends of the two pull rods located outside the cooling box. The handle allows workers to pull the two pull rods and then pull the sliding frame.

[0013] Compared with the prior art, the utility model provides an alkaline washed absorption oil cooler. When the absorption oil moves from the absorption oil inlet pipe to the bottom of the cooling box, the absorption oil will flow through the filter screen and the outside of the heat exchange tube. The filter screen filters the absorption oil. After the absorption oil flows through the outside of the heat exchange tube for a long time, impurities and stains will accumulate on the outside of the heat exchange tube, affecting the heat exchange between the heat exchange tube and the absorption oil. Therefore, the sliding frame is caused to slide by pulling the pull rod at regular intervals, and the sliding of the sliding frame can enable the cleaning ring to clean the heat exchange tube. At this time, the filter screen can still filter the absorption oil. At this time, on the one hand, the absorption oil can be decontaminated to improve the role of the absorption oil in the alkaline washing system. On the other hand, impurities can be prevented from accumulating on the heat exchange tube for a long time and affecting the heat exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1-6, an alkali washing absorption oil cooler provided by an embodiment of the utility model comprises a cooling box 1 and a heat exchange component 2, the cooling box 1 is connected with an absorption oil inlet pipe 11 and an absorption oil outlet pipe 12, the heat exchange component 2 comprises a liquid inlet main pipeline 21, a liquid outlet main pipeline 22 and a plurality of heat exchange tubes 23, each heat exchange tube 23 is located in the cooling box 1, and one end of each heat exchange tube 23 is connected with the liquid inlet main pipeline 21, and the other end is connected with the liquid outlet main pipeline 22; it also comprises two sliding frames 3 inserted together and at least one sliding frame 3 is fixedly connected with a pull rod 32, specifically, there are two pull rods 32, the two pull rods 32 are screwed with the two sliding frames 3 in a one-to-one correspondence, a handle 321 is provided between the ends of the two pull rods 32 located outside the cooling box 1, the handle 321 can facilitate the worker to pull the two pull rods 32 and then facilitate the pulling of the sliding frame 3, and the pull rod 32 is screwed on the sliding frame. In order to facilitate the removal of the sliding frame 3 after the pull rod 32 is removed from the sliding frame 3 without affecting the stability of the connection between the pull rod 32 and the sliding frame 3; the two sliding frames 3 are vertically slidably connected in the cooling box 1, and the two sliding frames 3 are respectively provided with filter screens 4. Specifically, the filter screen 4 is fixedly connected with a filter screen frame 41 around it, and the filter screen 4 is inserted into the corresponding sliding frame 3 through the filter screen frame 41. When the filter screen 4 is replaced, it is only necessary to slide the filter screen frame 41 out of the sliding frame and replace the new filter screen 4 and the new filter screen frame 41. Reducing the steps of replacing the filter screen 4 can effectively improve the work efficiency; a plurality of one-to-one corresponding semicircular rings 31 are respectively provided on the opposite sides of the two sliding frames 3, and the two corresponding semicircular rings 31 can be combined to form a circular cleaning ring 311, and each cleaning ring 311 is slidably sleeved and connected with each heat exchange tube 23 in a one-to-one manner; the pull rod 32 vertically passes through the top of the cooling box 1.

[0025] In this embodiment, the coolant first needs to flow into the liquid inlet main pipe 21, the coolant flows along the liquid inlet main pipe 21 into the heat exchange tube 23, and then flows from the heat exchange tube 23 to the liquid outlet main pipe 22 (the flow of the coolant will form a cycle, and other devices are involved. This is the prior art and will not be described in detail here). Then, the absorption oil flows from the absorption oil inlet pipe 11 into the cooling box 1. The absorption oil entering the cooling box 1 will first pass through the filter screen 4. At this time, the filter screen 4 will filter the impurities in the absorption oil. The absorption oil will accumulate at the bottom of the cooling box 1, but at this time, the heat exchange tube 23 is in contact with the absorption oil to cool the absorption oil. In this process, the pull rod 32 can be pulled to drive the slide The frame 3 moves, and the movement of the two sliding frames 3 will move with the cleaning ring 311. The movement of the cleaning ring 311 can clean the impurities accumulated on the heat exchange tube 23 to avoid affecting the heat exchange efficiency of the heat exchange tube 23. At this time, on the basis of the heat exchange work of the cooling box 1 on the absorption oil, the absorption oil is filtered and the heat exchange tube 23 is cleaned. After completing these tasks, the absorption oil is discharged from the absorption oil outlet pipe 12, and then the flow of the coolant is stopped. It is worth mentioning that sealing strips are arranged around the sliding frame 3 (not shown in the figure, this is the prior art) to prevent the absorption oil from flowing through the gap between the sliding frame 3 and the inner wall of the cooling box 1.

[0026] The utility model provides an alkaline washed absorption oil cooler. When the absorption oil moves from the absorption oil inlet pipe 11 to the bottom of the cooling box 1, the absorption oil will flow through the filter screen 4 and the outside of the heat exchange tube 23. The filter screen 4 filters the absorption oil. After the absorption oil flows through the outside of the heat exchange tube 23 for a long time, impurities and stains will accumulate on the outside of the heat exchange tube 23, affecting the heat exchange between the heat exchange tube 3 and the absorption oil. Therefore, the sliding frame 3 is caused to slide by pulling the pull rod 32 at regular intervals, and the sliding of the sliding frame 3 can enable the cleaning ring 311 to clean the heat exchange tube 23. At this time, the filter screen 4 can still filter the absorption oil. At this time, on the one hand, the absorption oil can be decontaminated to improve the role played by the absorption oil in the alkaline washing system, and on the other hand, the impurities can be prevented from accumulating on the heat exchange tube 23 for a long time and affecting the heat exchange efficiency.

[0027] Among them, a spray assembly is provided on one end of the absorption oil inlet pipe 11 located in the cooling box 1, and the spray assembly includes a transverse pipe 5 and a plurality of spray nozzles 51 distributed transversely in parallel. The transverse pipe 5 is connected to the absorption oil inlet pipe 11, and each spray nozzle 51 is connected to the transverse pipe 5. Each spray nozzle 51 is used to spray absorption oil to the heat exchange tube 23. The absorption oil flows from the absorption oil inlet pipe 11 to the transverse pipe 5, and then is sprayed out by the spray nozzle 51 on the transverse pipe 5. The spray nozzle 51 is toward the heat exchange tube 23 close to the liquid inlet main pipe 21, and the absorption oil is sprayed to the heat exchange tube 23 through the spray nozzle 51, so that the absorption oil can contact the heat exchange tube 23 earlier for cooling, and the spray nozzle 51 sprays the absorption oil to increase the contact area between the absorption oil and the heat exchange tube 23, thereby effectively improving the heat exchange efficiency.

[0028] A rubber half ring (not shown in the figure) is arranged in each semicircular ring 31. When the semicircular ring 31 is cleaning the heat exchange tube 23, the rubber half ring is used to prevent the absorbed oil from flowing through the gap between the two semicircular rings 31, and also to prevent the absorbed oil from flowing through the gap between the semicircular ring 31 and the heat exchange tube 23, thereby indirectly improving the filtering quality.

[0029] Among them, side windows are opened on the opposite sides of the cooling box 1, and the two side windows are detachably connected with sealing plates 13 that can close the corresponding side windows. The filter 4 is in a constant working state and needs to be replaced regularly. In addition, the semicircular ring 31 scrapes the heat exchange tube 23, so the wear of the semicircular ring 31 is also large and needs to be replaced regularly. Therefore, when it is necessary to replace the filter 4 or the semicircular ring 31, the sealing plate 13 is opened to expose the side window to the outside, and the internal filter 4 and filter frame 41 are taken out from the side window, or the filter frame 41 is taken out first and then the sliding frame 3 is taken out to replace the filter 4 or the semicircular ring 31. It is worth mentioning that the vertical opening height of the side window here is greater than the thickness of the sliding frame, which will be convenient for the worker to replace it.

[0030] The top of the cooling box 1 is detachably connected with a cover plate 14. By opening the cover plate 14, the working conditions inside the cooling box 1 can be observed. On the other hand, after opening the cover plate 14, the pipes in the cooling box 1 can be replaced, repaired, etc.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
