Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of coking, and specifically relates to a tar liquid level detection device and a using method thereof. Background Art
[0002] The gas and liquid in the coke oven gas generated by coking are separated by a gas-liquid separator, and the liquid enters a mechanized ammonia water clarifying tank. The liquid contains ammonia water, tar, and tar residue, which are separated in the mechanized ammonia water clarifying tank by gravity sedimentation. The upper part is ammonia water, the middle part is tar, and the lower part is tar residue. When the ammonia water level in the clarifying tank reaches the overflow pipe, it is discharged into the ammonia water intermediate tank. The tar residue is continuously discharged into the slag receiving tank by a chain conveyor for 24 hours, while the tar needs to be manually pressed into the tar intermediate tank with oil pressure.
[0003] The oil pressing operation must clarify the oil level of the tar. Otherwise, ammonia water and tar residue will enter the tar product, affecting the quality of the tar. The existing technologies use ultrasonic level gauges, float level gauges, and radar level gauges to detect the oil level of the tar. However, during the use process, due to the high viscosity of the tar, the deviation is large, and it is easily blocked by the tar and cannot be used. At the same time, the operator at this position needs to go to the site every hour to judge based on experience whether it is possible to press oil and whether ammonia water is entrained. During the oil pressing process, the operator needs to climb to the top of the mechanized ammonia water clarifying tank every 15 minutes to observe whether tar residue is entrained during the oil pressing. Therefore, the existing technologies have problems such as the quality of the tar cannot be accurately controlled, the labor intensity of the post workers is large, the VOCs cannot close the observation hole, and the volatile harmful gases escape into the air, polluting the air and endangering the health of the workers.

[0030] Please refer to Figure 8, an embodiment provided by the present invention: a method for using a tar liquid level detection device, including step one, installing the device; step two, debugging the device; step three, monitoring the oil level; step four, automatically pressing the oil;
[0031] In the above step one, first install five monitoring components 3 on the driving component 2, connect the circuits of the motor 20, the electromagnet 32, the controller 38, the temperature monitor 39 and the external electric control equipment, and then install the driving component 2 equipped with the monitoring components 3 on the clarification tank, and set the monitoring components 3 in the clarification tank;
[0032] In the above step two, the liquid level of tar in the clarification tank is controlled at 500-1500 mm, and the positions of the five monitoring components 3 are adjusted through the driving component 2 so that they are respectively 500 mm, 800 mm, 1100 mm, 1400 mm and 1700 mm away from the bottom of the clarification tank, so as to obtain 5 temperature measurement points;
[0033] In the above step three, the external electric control equipment automatically judges the liquid level according to the temperatures of the 5 temperature measurement points obtained in step two; among them, the basis for judging the liquid level is: the ammonia water temperature > 60 °C, the tar-ammonia emulsion temperature is 40-50 °C, the tar temperature is 30-40 °C, and the tar residue temperature < 30 °C.
[0034] In the above step four, if the temperatures monitored by the 4 temperature measurement points from bottom to top in step three are lower than 40 °C and the temperature displayed by the 5th temperature measurement point is higher than 40 °C, then start pressing the oil; if the temperature of the 1st temperature measurement point rises to be close to 40 °C and the temperatures of the 2nd-5th temperature measurement points are higher than the temperature of the 1st temperature measurement point, then stop pressing the oil.
[0035] Based on the above, when performing the oil pressing operation using the present invention, it is necessary to debug and monitor the position of the monitoring component 3 through the driving component 2. Specifically: an instruction is sent from an external electronic control device to the monitoring component 3 whose position needs to be adjusted. The controller 38 receives the instruction and controls the electromagnet 32 to act.

The motor 20 is started, and the worm 22 drives the worm gear 24. The first pulley 25 on the worm gear 24 rotates accordingly. The first pulley 25 drives the synchronous belt 26 to transmit power. Since one side edge of the synchronous belt 26 is pressed by the second clamping block 37, the housing 30 can be driven to lift. While the housing 30 is lifting, the pulley 31 rolls along the guide rail 28 to assist the housing 30 in lifting. After adjusting to the required height, the electromagnet 32 and the motor 20 stop acting. Under the action of the spring 35, the connecting rod 33 drives the first clamping block 36 to reset and re-engage with the rack 27, fixing the housing 30 at this height. The temperature monitor 39 monitors the temperature here and transmits the data to the external electronic control device, thereby realizing the liquid level monitoring. Among them, the cover plate 1 is used to seal the installation hole on the clarification tank, the handle 10 is used to facilitate the taking and placing of the cover plate 1, the first rotating shaft 23 on the first bracket 21 is used to install the worm gear 24, the second rotating shaft 210 on the second bracket 29 is used to install the second pulley 211, the second pulley 211 is used to assist in driving the synchronous belt 26, the first through groove 300 is used to accommodate the rack 27, the limiting groove 301 is used to accommodate the electromagnet 32, the spring 35 and the iron sheet 34, the accommodating groove 303 is used to accommodate the second clamping block 37, and the second through groove 304 is used to accommodate the synchronous belt 26.
