Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ammonia desulfurization systems, specifically to a high-efficiency solid-liquid separation device for ammonia desulfurization systems. Background Technology
[0002] Ammonia desulfurization is a highly efficient and low-energy-consumption wet desulfurization method. The desulfurization process involves a gas-liquid phase reaction with a fast reaction rate and high absorbent utilization, maintaining a desulfurization efficiency of 95-99%. Ammonia has a solubility in water exceeding 20%, making solid-liquid separation a necessary step in the ammonia desulfurization process. Through solid-liquid separation, ammonium sulfate crystals can be separated from the mother liquor for further processing and recycling.
[0003] Existing solid-liquid separation devices rely solely on a single washing nozzle to clean the raw material, failing to adequately clean the material on the filter cloth and thus affecting the solid-liquid separation effect. Furthermore, the lack of an effective pressing device prevents the material from being evenly compacted on the filter cloth during feeding, hindering subsequent washing processes. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a high-efficiency solid-liquid separation device for ammonia desulfurization systems. By setting three washing tanks, washing pipes and washing nozzles, the washing nozzles on the three washing pipes are set at equal intervals, so that the raw materials moving on the filter cloth can be uniformly and fully washed by the washing nozzles, ensuring the solid-liquid separation effect of the raw materials, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency solid-liquid separation device for an ammonia desulfurization system, comprising a vacuum water collection tank, a rubber belt on the upper side of the vacuum water collection tank, a filter cloth on the upper side of the rubber belt, both the rubber belt and the filter cloth being annular structures, three washing tanks on the upper side of the filter cloth, a washing pipe arranged horizontally in the washing tank, washing nozzles evenly spaced on the lower side of the washing pipe, a feed box on one side of one of the washing tanks, a feed pipe fixedly connected to the upper side of the feed box, a pressing cylinder on the outer side of the feed pipe, and a feed pressure plate on the lower side of the pressing cylinder.
[0006] Furthermore, conveying rollers are provided at both ends of the rubber belt, and a discharge plate is provided on the outside of one of the conveying rollers. A washing assembly is provided on the upper and lower sides of the filter cloth under the discharge plate.
[0007] Furthermore, a second flushing assembly is provided on the upper and lower sides of the rubber belt on the lower side of the vacuum water collection tank, and a second water collection tank is provided on the lower side of the second flushing assembly.
[0008] Furthermore, a water collection tank is provided at the lower part of the filter cloth on the lower side. A vacuum pump is connected to the vacuum water collection tank through a pipe, and a gas-liquid separator is connected to the pipe of the vacuum water collection tank.
[0009] Furthermore, guide rollers are provided at the inner and outer sides of the filter cloth and at the bottom of the rubber belt. The guide rollers and the conveying rollers are connected to the support frame of the separation device through bearing seats.
[0010] Furthermore, the feed box is rotatably connected to the feed pressure plate, the lower end of the pressing cylinder is hinged to the feed pressure plate, and the washing pipe is fixedly connected to the washing nozzle.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model features three washing tanks, washing pipes, and washing nozzles. The washing nozzles on the three washing pipes are evenly spaced, allowing the raw materials moving on the filter cloth to be washed evenly and thoroughly by the washing nozzles, thus ensuring the solid-liquid separation effect of the raw materials.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This embodiment provides a technical solution: a high-efficiency solid-liquid separation device for an ammonia desulfurization system, including a vacuum water collection tank 5, a rubber belt 4 on the upper side of the vacuum water collection tank 5, a filter cloth 1 on the upper side of the rubber belt 4, both the rubber belt 4 and the filter cloth 1 are annular structures, three washing tanks 12 are provided on the upper side of the filter cloth 1, washing pipes 16 are arranged horizontally in the washing tanks 12, washing nozzles 17 are arranged at equal intervals on the lower side of the washing pipes 16, a feed box 11 is provided on one side of one of the washing tanks 12, a feed pipe 13 is fixedly connected to the upper side of the feed box 11, a pressing cylinder 19 is provided on the outer side of the feed pipe 13, and a feed pressure plate 18 is provided on the lower side of the pressing cylinder 19.
[0021] like Figure 1-4 As shown, during use, the raw materials requiring solid-liquid separation are fed into the feed pipe 13. The raw materials are in the feed box 11, and the pressing cylinder 19 pushes the feed plate 18 downwards, compacting the raw materials conveyed on the filter cloth 1. The compacted raw materials are then conveyed to the lower side of the washing tank 12. Washing water is sprayed out through the washing nozzle 17 at the lower side of the washing pipe 16, thus performing reverse washing on the raw materials. During the moving and conveying process of the washed raw materials, the vacuum pump 14 creates a vacuum inside the vacuum water collection tank 5 through the pipeline, causing the water in the raw materials to be removed. Under the action of force and negative pressure, it enters the vacuum water collection tank 5 and flows into the gas-liquid separator 15 through the pipeline for gas-liquid separation. The raw material after solid-liquid separation moves along the filter cloth 1. After moving to the position of the discharge plate 6, the discharge plate 6 can scrape off the separated solid material on the filter cloth 1. The filter cloth 1 continues to move downward. The first flushing component 7 can flush the filter cloth 1. The flushed water falls into the first water collection tank 8. The second flushing component 10 can flush the rubber belt 4. The flushed wastewater flows into the second water collection tank 9.
[0022] The rubber belt 4 has conveying rollers 3 at both ends inside, and a discharge plate 6 is provided on the outside of one of the conveying rollers 3. A first rinsing component 7 is provided on the upper and lower sides of the filter cloth 1 under the discharge plate 6.
[0023] The second flushing assembly 10 is installed on the upper and lower sides of the rubber belt 4 on the lower side of the vacuum water collection tank 5, and the second water collection tank 9 is installed on the lower side of the second flushing assembly 10.
[0024] A water collection tank 8 is installed at the bottom of the filter cloth 1 on the lower side. A vacuum pump 14 is connected to the vacuum water collection tank 5 through a pipe. A gas-liquid separator 15 is connected to the pipe of the vacuum water collection tank 5.
[0025] Guide rollers 2 are provided on the inner and outer sides of filter cloth 1 and the bottom of rubber belt 4. Guide rollers 2 and conveying rollers 3 are connected to the support frame of the separation device through bearing seats.
[0026] The feed box 11 is rotatably connected to the feed pressure plate 18, the lower end of the pressing cylinder 19 is hinged to the feed pressure plate 18, and the washing pipe 16 is fixedly connected to the washing nozzle 17.
[0027] The working principle of the high-efficiency solid-liquid separation device for an ammonia desulfurization system provided by this utility model is as follows: Figures 1-4 As shown, during use, the raw materials requiring solid-liquid separation are fed into the feed pipe 13. The raw materials are in the feed box 11, and the pressing cylinder 19 pushes the feed plate 18 downwards, compacting the raw materials conveyed on the filter cloth 1. The compacted raw materials are then conveyed to the lower side of the washing tank 12. Washing water is sprayed out through the washing nozzle 17 at the lower side of the washing pipe 16, thus performing reverse washing on the raw materials. During the moving and conveying process of the washed raw materials, the vacuum pump 14 creates a vacuum inside the vacuum water collection tank 5 through the pipeline, causing the water in the raw materials to be removed. Under the action of force and negative pressure, it enters the vacuum water collection tank 5 and flows into the gas-liquid separator 15 through the pipeline for gas-liquid separation. The raw material after solid-liquid separation moves along the filter cloth 1. After moving to the position of the discharge plate 6, the discharge plate 6 can scrape off the separated solid material on the filter cloth 1. The filter cloth 1 continues to move downward. The first flushing component 7 can flush the filter cloth 1. The flushed water falls into the first water collection tank 8. The second flushing component 10 can flush the rubber belt 4. The flushed wastewater flows into the second water collection tank 9.
