Description

Technical Field

[0001] This utility model relates to the field of coal gas purification technology, and in particular to a high-efficiency tar separation device in a coal gas purification system for a coal chemical plant. Background Technology

[0002] As is well known, the tar and ammonia produced in the coal coking process need to be separated. Generally, the separation is carried out by the difference in density. Since tar is relatively viscous, it is easy to clog the tar pipe. Therefore, it is necessary to design a tar-ammonia separation device with an oil discharge mechanism for coal gas purification.

[0003] Some existing separation devices are not very practical because the high viscosity of tar can easily clog the tar pipe. Furthermore, tar residue tends to accumulate during the separation process, and if the tar residue is large, it may not be able to be discharged, leading to further accumulation of tar residue.

[0004] To address this issue, this utility model proposes a high-efficiency tar separation device for a coal gas purification system in a coal chemical plant. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose a high-efficiency tar separation device in a coal gas purification system of a coal chemical plant, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a high-efficiency tar separation device in a coal gas purification system of a coal chemical plant, comprising a tar-ammonia-water separation device body, a hydraulic cylinder fixedly connected to each of the two sides of the tar-ammonia-water separation device body, a top cover fixedly connected to the top of the two hydraulic cylinders, a motor fixedly connected to the top of the top cover, a stirring and conveying device fixedly connected to the output end of the motor, and a tar residue filter screen slidably connected inside the tar-ammonia-water separation device body.

[0008] Preferably, in any of the above embodiments, four support legs are fixedly connected around the body of the tar-ammonia-water separation device, and a tar outlet and an ammonia water outlet are fixedly connected to the bottom and one side of the body of the tar-ammonia-water separation device, respectively, and valves are installed on both the tar outlet and the ammonia water outlet.

[0009] Preferably, in any of the above embodiments, a connecting block is fixedly connected to both sides of the main body and the top cover of the tar-ammonia-water separation device, and the upper and lower sides of the hydraulic cylinder are respectively fixedly connected to the connecting blocks.

[0010] Preferably, in any of the above embodiments, the stirring and conveying device includes a rotating shaft, which is rotatably connected to the top cover, and several stirring rods are fixedly connected to both sides of the rotating shaft.

[0011] Preferably, in any of the above embodiments, a screw conveyor is fixedly connected to the bottom of the rotating shaft, and the screw conveyor is rotatably connected to the inside of the tar outlet.

[0012] Preferably, in any of the above embodiments, the diameter of the tar residue filter screen is adapted to the internal diameter of the tar-ammonia-water separation device body, and the tar residue filter screen is slidably connected to the inside of the tar-ammonia-water separation device body.

[0013] Preferably, in any of the above embodiments, a sliding groove is provided on each of the two sides inside the body of the tar ammonia water separation device, and a slider is fixedly connected to each of the two sides of the tar residue filter screen.

[0014] Preferably, in any of the above solutions, the shape of the slider is adapted to the shape of the groove, and the two sliders are slidably connected inside the two grooves respectively.

[0015] Preferably, one side of the rotating shaft is provided with a rotating groove, and the middle of the tar residue filter screen is provided with a rotating hole. The tar residue filter screen is rotatably connected to the rotating shaft through the cooperation of the rotating hole and the rotating groove.

[0016] Preferably, in any of the above embodiments, the bottoms of the two stirring rods are in contact with the upper surface of the tar residue filter screen.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0018] During normal separation reaction, the stirring rod scrapes the upper surface of the tar residue filter screen as it rotates, preventing the tar residue from accumulating in one place for a long time and preventing the separated tar from flowing downwards. When it is necessary to clean the tar residue, the two hydraulic cylinders are controlled to raise the top cover so that the upper surface of the tar residue filter screen is flush with the top of the tar ammonia water separator. Then, the motor drives the rotating shaft to rotate, which scrapes off the tar residue filtered from the tar residue filter screen, collects it with tools, and processes it centrally.

Detailed Implementation

[0027] like Figures 1 to 5 As shown, the high-efficiency tar separation device in the coal gas purification system of a coal chemical plant includes a tar-ammonia-water separation device body 1. A hydraulic cylinder 2 is fixedly connected to each side of the tar-ammonia-water separation device body 1. A top cover 3 is fixedly connected to the top of the two hydraulic cylinders 2. A motor 4 is fixedly connected to the top of the top cover 3. A stirring and conveying device 5 is fixedly connected to the output end of the motor 4. A tar residue filter screen 6 is slidably connected inside the tar-ammonia-water separation device body 1.

[0028] Four support legs 101 are fixedly connected around the body 1 of the tar ammonia water separation device. A tar outlet 102 and an ammonia water outlet 103 are fixedly connected to the bottom and one side of the body 1 of the tar ammonia water separation device. Valves are installed on both the tar outlet 102 and the ammonia water outlet 103 to discharge ammonia water from the ammonia water outlet 103.

[0029] A connecting block 104 is fixedly connected to both sides of the tar ammonia water separation device body 1 and the top cover 3. The upper and lower sides of the hydraulic cylinder 2 are fixedly connected to the connecting block 104 respectively. A sealing ring is provided between the tar ammonia water separation device body 1 and the top cover 3. A feeding port is fixedly connected to the top of the top cover 3.

[0030] The stirring and conveying device 5 includes a rotating shaft 501, which is rotatably connected to the top cover 3. Several stirring rods 502 are fixedly connected to both sides of the rotating shaft 501. By setting the stirring rods 502, the raw liquid to be separated can be mixed more evenly, thereby improving the separation effect.

[0031] A screw conveyor 503 is fixedly connected to the bottom of the rotating shaft 501. The screw conveyor 503 is rotatably connected to the inside of the tar outlet 102. By setting the screw conveyor 503, the screw conveyor 503 plays the role of stirring and conveying downward. During the rotation, it will drive the tar to flow downward continuously, so as to avoid the tar being too viscous and clogging the tar outlet 102.

[0032] The diameter of the tar residue filter screen 6 is adapted to the internal diameter of the tar ammonia water separator body 1. The tar residue filter screen 6 is slidably connected to the inside of the tar ammonia water separator body 1. After the reaction, the separated tar will flow downward through the tar residue filter screen 6, while the tar residue will be blocked above the tar residue filter screen 6.

[0033] A sliding groove 105 is provided on each of the two sides inside the main body 1 of the tar ammonia water separation device, and a slider 601 is fixedly connected to each of the two sides of the tar residue filter screen 6.

[0034] The shape of the slider 601 is adapted to the shape of the groove 105. The two sliders 601 are slidably connected inside the two grooves 105 respectively. Through the cooperation of the grooves 105 and the sliders 601, the tar residue filter screen 6 can be limited so that it can only slide up and down and will not rotate.

[0035] A rotating groove 504 is provided on one side of the rotating shaft 501, and a rotating hole 602 is provided in the middle of the tar residue filter screen 6. The tar residue filter screen 6 is rotatably connected to the rotating shaft 501 through the cooperation of the rotating hole 602 and the rotating groove 504. This cooperation allows the rotating shaft 501 to drive the tar residue filter screen 6 to slide up and down when it moves up and down, but it will not drive the tar residue filter screen 6 to rotate when it rotates.

[0036] The bottoms of the two stirring rods 502 are in contact with the upper surface of the tar residue filter screen 6. During the normal separation reaction, the stirring rods 502 scrape the upper surface of the tar residue filter screen 6 as they rotate, preventing the tar residue from accumulating in one place for a long time and preventing the separated tar from flowing downwards. When it is necessary to clean the tar residue, the two hydraulic cylinders 2 are controlled to drive the top cover 3 to rise, so that the upper surface of the tar residue filter screen 6 is flush with the top of the tar ammonia water separator body 1. The motor 4 is then controlled to drive the rotating shaft 501 to rotate, so that the tar residue filtered from the tar residue filter screen 6 can be scraped off, collected with tools, and centrally processed.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] During normal separation reaction, the stirring rod 502 scrapes the upper surface of the tar residue filter screen 6 as it rotates, preventing the tar residue from accumulating in one place for a long time and preventing the separated tar from flowing downwards. When it is necessary to clean the tar residue, the two hydraulic cylinders 2 are controlled to drive the top cover 3 to rise, so that the upper surface of the tar residue filter screen 6 is flush with the top of the tar ammonia water separator body 1. The motor 4 is then controlled to drive the rotating shaft 501 to rotate, so that the tar residue filtered from the tar residue filter screen 6 can be scraped off, collected with tools, and centrally processed.
