Description
Technical Field
[0001] This utility model relates to the field of ammonium sulfate waste liquid filtration in the coking industry, and particularly to an ammonium sulfate waste liquid filtration device for the coking industry. Background Technology
[0002] The coal gas containing impurities is washed and reacted with 2% dilute sulfuric acid. The impurities in the coal gas are absorbed in a circulating cycle. The purified coal gas then enters the next process for further washing until saturation, after which ammonium sulfate is produced. The waste liquid mixture resulting from the reaction of sulfuric acid and impurities requires further treatment.
[0003] Existing methods for treating mixed waste liquids involve natural sedimentation. The waste liquid is placed in a large sedimentation tank, and after a long period of settling, the heavier solid particles gradually settle to the bottom, while the lighter liquid components float on top, thus separating them. However, this method takes a long time, possibly several hours to several days, requires a large area, has limited separation efficiency, and is ineffective for fine particles or low-concentration suspended solids. Utility Model Content
[0004] The main purpose of this utility model is to provide a device for treating ammonium sulfate waste liquid in the coking industry, which can effectively solve the technical problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A device for treating ammonium sulfate waste liquid in the coking industry includes a lower tank, with an upper tank positioned directly above it. An inlet pipe is located on one side of the lower tank, and a support plate is fixedly connected to one side of the lower tank. A tube plate is positioned at the top of the lower tank, and the other side of the tube plate is attached to the bottom of the upper tank. An installation frame is installed inside the tube plate, and several filter membranes are mounted on the installation frame in an equally spaced array. Two sets of connecting grooves are formed on the tube plate, and connecting blocks are installed within the connecting grooves. One end of each connecting block is fixedly connected to one side of the installation frame, and a first bolt is installed on each connecting block, with one end of the first bolt threadedly connected to one side of the connecting groove. A sealing assembly is installed at the tube plate to enhance the sealing performance of the connections.
[0007] As a further embodiment of this utility model, the sealing assembly includes a first sealing groove formed on one side of the upper barrel, a first sealing ring disposed in the first sealing groove, and one side of the first sealing ring being fixedly connected to one side of the tube sheet.
[0008] As a further embodiment of this utility model, the sealing assembly further includes a second sealing groove formed on one side of the lower barrel, a second sealing ring being provided in the second sealing groove, and one side of the second sealing ring being fixedly connected to the other side of the tube sheet.
[0009] As a further embodiment of this utility model, two sets of mounting plates are fixedly connected to the support plate. The two sets of mounting plates are symmetrically distributed about the central axis of the support plate, and each set of mounting plates is provided with a fixing groove.
[0010] As a further embodiment of this utility model, a fixing plate is provided on one side of the tube sheet, and both ends of the fixing plate are respectively inserted into fixing grooves. Two sets of second bolts are provided on the mounting plate, and one end of the second bolt is threadedly connected to the fixing plate.
[0011] As a further embodiment of this utility model, a drain pipe is provided on the upper barrel and an air inlet pipe is provided on the lower barrel.
[0012] As a further embodiment of this utility model, a slag discharge pipe is fixedly connected to the lower barrel body, and a valve is provided on the slag discharge pipe.
[0013] The beneficial effects of this utility model are as follows:
[0014] The mounting bracket is placed inside the tube sheet, the connecting block is inserted into the connecting groove, and then the first bolt is threaded to one side of the connecting groove to securely connect the mounting bracket to the tube sheet, fixing several filter membranes onto the tube sheet. The tube sheet is then placed between the upper and lower tanks, and the connection is sealed using a sealing assembly. The waste liquid mixture enters the lower tank through the inlet pipe. The waste liquid inside the lower tank gradually moves upward, where it is first adsorbed by several filter membranes, removing the dirt from the wastewater. The treated water then moves through the holes in the tube sheet to the upper tank, thus completing the wastewater treatment. This significantly reduces the time required for wastewater treatment, thereby improving the efficiency of wastewater treatment. At the same time, it greatly reduces the required floor space, improves the separation effect of wastewater, and enhances the treatment effect of fine particles or low-concentration suspended solids, thereby improving the overall efficiency of wastewater treatment operations.
[0015] The treated clean water in the upper tank flows out through the drain pipe. Compressed air enters the lower tank through the inlet pipe to discharge the liquid in the equipment and dry the filter cake. The dirt and residue that settle in the lower tank are discharged out through the slag discharge pipe for easy waste treatment. At the same time, the valve controls the opening and closing of the slag discharge pipe to prevent wastewater from leaking out during wastewater treatment. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1-6 As shown, the ammonium sulfate waste liquid treatment device for the coking industry includes a lower tank 2, an upper tank 1 located directly above the lower tank 2, an inlet pipe 22 located on one side of the lower tank 2, a support plate 13 fixedly connected to one side of the lower tank 2, a tube plate 3 located on the top of the lower tank 2, and the other side of the tube plate 3 being attached to the bottom of the upper tank 1; an installation frame 5 is installed inside the tube plate 3, and several filter membranes 4 are installed on the installation frame 5, which are evenly distributed in an array; two sets of connecting grooves 6 are opened on the tube plate 3, and connecting blocks 7 are installed in the connecting grooves 6; the filter membranes 4 used are made of a new type of flexible material, with smooth double surfaces, easy filter cake removal, short filtration channels, and are not prone to scaling and clogging.
[0025] In this embodiment, one end of the connecting block 7 is fixedly connected to one side of the mounting bracket 5, and a first bolt 8 is provided on the connecting block 7. One end of the first bolt 8 is threadedly connected to one side of the connecting groove 6. A sealing component is provided at the tube sheet 3, which is used to increase the sealing of the connection.
[0026] To facilitate wastewater treatment, the mounting bracket 5 is first placed inside the tube sheet 3, the connecting block 7 is inserted into the connecting groove 6, and then the mounting bracket 5 is securely connected to the tube sheet 3 by threading the first bolt 8 to one side of the connecting groove 6, thus fixing several filter membranes 4 onto the tube sheet 3. The tube sheet 3 is then placed between the upper tank 1 and the lower tank 2, and the connection is sealed using a sealing assembly. The wastewater mixture is then introduced into the lower tank 2 through the inlet pipe 22. The wastewater in the lower tank 2 gradually moves upward, where it is first adsorbed by several filter membranes 4, removing the dirt from the wastewater. The treated water then moves through the holes in the tube sheet 3 into the upper tank 1, thus completing the wastewater treatment. This significantly reduces the time required for wastewater treatment, thereby improving the efficiency of wastewater treatment. At the same time, it greatly reduces the required floor space, improves the separation effect of wastewater, and enhances the treatment effect of fine particles or low-concentration suspended solids, thereby improving the overall efficiency of wastewater treatment operations.
[0027] Meanwhile, a drain pipe 18 is installed on the upper tank 1, and an air inlet pipe 19 is installed on the lower tank 2. A slag discharge pipe 20 is fixedly connected to the lower tank 2, and a valve 21 is installed on the slag discharge pipe 20. The treated clean water moved into the upper tank 1 flows out of the upper tank 1 through the drain pipe 18. Compressed air enters the lower tank 2 through the air inlet pipe 19 to discharge the liquid in the equipment and dry the filter cake. The dirt and residue that settle in the lower tank 2 are discharged out of the lower tank 2 through the slag discharge pipe 20, which facilitates the treatment of waste residue. At the same time, the valve 21 controls the opening and closing of the slag discharge pipe 20 to prevent wastewater from leaking to the outside when treating wastewater.
[0028] In this embodiment, the sealing assembly includes a first sealing groove 9 opened on one side of the upper barrel 1, a first sealing ring 11 is provided in the first sealing groove 9, and one side of the first sealing ring 11 is fixedly connected to one side of the tube plate 3.

[0029] When the tube sheet 3 is connected to the upper tank 1 and the lower tank 2, the first sealing ring 11 and the second sealing ring 12 are respectively inserted into the first sealing groove 9 and the second sealing groove 10 to seal the connection between the tube sheet 3 and the upper tank 1 and the lower tank 2, thereby increasing the airtightness of the equipment connection, preventing sewage from leaking from the connection when treating sewage, and increasing the stability of the equipment during use.
[0030] In this embodiment, two sets of mounting plates 15 are fixedly connected to the support plate 13. The two sets of mounting plates 15 are symmetrically distributed about the central axis of the support plate 13. Each set of mounting plates 15 has a fixing groove 16. A fixing plate 14 is provided on one side of the tube plate 3. Both ends of the fixing plate 14 are inserted into the fixing groove 16 respectively. Two sets of second bolts 17 are provided on the mounting plate 15. One end of the second bolt 17 is threadedly connected to the fixing plate 14.
[0031] After connecting the tube sheet 3 to the upper barrel 1 and the lower barrel 2, insert both ends of the fixing plate 14 into the fixing grooves 16 opened in the mounting plate 15, and then thread the second bolt 17 to the end of the fixing plate 14 to securely connect the fixing plate 14 and the mounting plate 15 together. This restricts the position of the tube sheet 3, prevents the tube sheet 3 from separating from the upper barrel 1 and the lower barrel 2, increases the stability of the equipment during use, and facilitates subsequent maintenance of the filter membrane 4.
[0032] It should be noted that this utility model is a device for treating ammonium sulfate waste liquid in the coking industry. In use, firstly, the mounting bracket 5 is placed inside the tube sheet 3, and the connecting block 7 is inserted into the connecting groove 6. Then, the first bolt 8 is threaded onto one side of the connecting groove 6 to securely connect the mounting bracket 5 and the tube sheet 3, fixing several filter membranes 4 onto the tube sheet 3. Next, the tube sheet 3 is placed between the upper tank 1 and the lower tank 2. The first sealing ring 11 and the second sealing ring 12 are respectively inserted into the first sealing groove 9 and the second sealing groove 10 to seal the connection between the tube sheet 3 and the upper tank 1 and the lower tank 2, increasing the sealing performance. Then, the waste liquid mixture is passed through… The wastewater enters the lower tank 2 through the inlet pipe 22 and gradually moves upward. First, it is adsorbed by several filter membranes 4 to remove the dirt from the wastewater. The treated water moves to the upper tank 1 through the holes of the tube plate 3, thus completing the treatment of the wastewater. The treated clean water in the upper tank 1 flows out of the upper tank 1 through the drain pipe 18. After the wastewater is treated, compressed air enters the lower tank 2 through the air inlet pipe 19 to discharge the liquid in the equipment and dry the filter cake. The dirt and residue that settle in the lower tank 2 are discharged out of the lower tank 2 through the slag discharge pipe 20 to treat the waste residue.
