Description

Technical Field

[0001] The invention relates to the field of desulfurization, and in particular to a method for improving the dehydration effect of magnesium-based desulfurization byproduct slurry improver. Background Art

[0002] At present, thermal power companies are affected by factors such as frequent peak-shaving of units and coal prices, resulting in frequent fluctuations in coal sulfur content and unit load. The desulfurization system of this unit adopts magnesium oxide desulfurization. The current design value of the unit's coal sulfur content is 1.7%, and the daily steam supply of the unit is maintained at around 250t / h, which leads to abnormal fluctuations in the slurry quality of the absorption tower in the desulfurization system. The slurry crystals in the absorption tower grow slowly and have difficulty in crystallization. As a result, the desulfurization by-product dehydration system has a filter cake moisture content of more than 20%, which is not dry after dehydration and difficult to transport. There are also extended dehydration time, slow density reduction in the absorption tower, deterioration of dehydration effect, transportation difficulties during transportation, and environmental risks.

[0003] In the early stage, the absorption tower was expanded and renovated by ultra-low emission modification. The absorption tower body was expanded from the original 29.5m to 32.5m, the tower body was increased by 3m, and a slurry circulation pump was added to improve the slurry liquid-to-gas ratio and slurry retention time in the absorption tower, and improve the desulfurization efficiency. In view of the existing high load and high sulfur content fluctuation conditions, the slurry crystal particle size in the absorption tower is below 15um, accounting for more than 50%, which cannot fully adapt to the existing working conditions.

[0004] Therefore, it is necessary to provide a method for providing a slurry modifier for improving the dehydration effect of magnesium-based desulfurization by-products to solve the above technical problems. Summary of the invention

[0005] The invention provides a method for improving the dehydration effect of magnesium-based desulfurization byproduct slurry improver, which solves the problem that the current desulfurization system cannot fully adapt to the existing working conditions.

[0006] In order to solve the above technical problems, the present invention provides a method for improving the dehydration effect of magnesium-based desulfurization byproduct slurry improver, comprising the following steps:

[0007] S1: First, estimate the total amount of slurry based on the diameter and liquid level of the absorption tower. In principle, the content of the reagent in the slurry should reach 6-12ppm;

[0008] S2: The first addition must be made in a shock-like manner to increase the concentration of the agent in the slurry as quickly as possible. The amount of the agent can be appropriately increased according to the quality of the slurry;

[0009] S3: When there is foam in the absorption tower, especially dark foam, as long as the foam does not overflow to the ground and cause environmental pollution, it is recommended to add it to the pit 30 minutes before each dehydration;

[0010] S4: When the quality of the filter cake is very poor, add medicine to the underflow box of the cyclone station. Method: fix a medicine adding barrel on the underflow box, drill a 4-5mm hole on the bottom of the side, prepare an empty medicine barrel, mix the medicine and water in a ratio of 1:1, add the medicine to the barrel after sufficient stirring, and start adding medicine by aiming at the observation hole of the underflow box. Generally, the filter cake begins to change after 2-3 minutes. The amount of medicine added can be fine-tuned according to the cake thickness. The medicine returns to the absorption tower with the filtrate, and after being stirred by the agitator of the absorption tower, it returns to the cyclone station with the slurry. This is a virtuous cycle, and the quality of the filter cake improves rapidly.

[0011] S5: When the absorption tower foams seriously, the pit is used for simultaneous application. No dilution is required when adding the medicine in the pit. The dosage is added according to the foam situation on site to help the toxins in the absorption tower to be discharged with the slurry.

[0012] S6: Track the filter cake quality every day. When it improves, reduce the dosage appropriately and enter the slurry activity recovery stage;

[0013] S7: Check and observe the changes in the slurry every day, and fine-tune the dosage again according to the changes in the slurry circulation pump current and discharge port data;

[0014] S8: When the quality of slurry and filter cake returns to normal, the cyclone station can stop adding chemicals, but 1-3L of chemicals should still be added to the pit every day to maintain the concentration of chemicals in the absorption tower slurry, which is the slurry activity maintenance stage.

[0015] A method for improving the dehydration effect of magnesium-based desulfurization byproducts using a slurry modifier, such as the drug dispensing barrel used in step S4, comprises: a tank body, a discharge pipe is fixedly connected to the top of the tank body, and two feed pipes are fixedly connected to the top of the tank body.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0035] First embodiment

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a method for a slurry modifier for improving the dehydration effect of magnesium-based desulfurization byproducts provided by the present invention;

[0037] Figure 2 for Figure 1 A schematic diagram of the structure of a sectional view of the tank body shown; Figure 3 for Figure 2 A schematic cross-sectional structural diagram of the reduction sleeve shown; Figure 4 for Figure 3 A method for improving the dehydration effect of magnesium-based desulfurization byproduct slurry improver comprises the following steps:

[0038] S1: First, estimate the total amount of slurry based on the diameter and liquid level of the absorption tower. In principle, the content of the reagent in the slurry should reach 6-12ppm;

[0039] S2: The first addition must be made in a shock-like manner to increase the concentration of the agent in the slurry as quickly as possible. The amount of the agent can be appropriately increased according to the quality of the slurry;

[0040] S3: When there is foam in the absorption tower, especially dark foam, as long as the foam does not overflow to the ground and cause environmental pollution, it is recommended to add it to the pit 30 minutes before each dehydration;

[0041] S4: When the quality of the filter cake is very poor, add medicine to the underflow box of the cyclone station. Method: fix a medicine adding barrel on the underflow box, drill a 4-5mm hole on the bottom of the side, prepare an empty medicine barrel, mix the medicine and water in a ratio of 1:1, add the medicine to the barrel after sufficient stirring, and start adding medicine by aiming at the observation hole of the underflow box. Generally, the filter cake begins to change after 2-3 minutes. The amount of medicine added can be fine-tuned according to the cake thickness. The medicine returns to the absorption tower with the filtrate, and after being stirred by the agitator of the absorption tower, it returns to the cyclone station with the slurry. This is a virtuous cycle, and the quality of the filter cake improves rapidly.

[0042] S5: When the absorption tower foams seriously, the pit is used for simultaneous application. No dilution is required when adding the medicine in the pit. The dosage is added according to the foam situation on site to help the toxins in the absorption tower to be discharged with the slurry.

[0043] S6: Track the filter cake quality every day. When it improves, reduce the dosage appropriately and enter the slurry activity recovery stage;

[0044] S7: Check and observe the changes in the slurry every day, and fine-tune the dosage again according to the changes in the slurry circulation pump current and discharge port data;

[0045] S8: When the quality of slurry and filter cake returns to normal, the cyclone station can stop adding chemicals, but 1-3L of chemicals should still be added to the pit every day to maintain the concentration of chemicals in the absorption tower slurry, which is the slurry activity maintenance stage.

[0046] The initial dosage of the slurry is usually the upper limit of the dosage appropriately increased according to the slurry quality.

[0047] A method for improving the dehydration effect of magnesium-based desulfurization byproducts using a slurry modifier, such as the drug dispensing barrel used in step S4, comprises: a tank body 1, a discharge pipe 2 is fixedly connected to the top of the tank body 1, and two feed pipes 10 are fixedly connected to the top of the tank body 1.

[0048] A stirring motor 3 is fixedly installed on the top of the tank body 1 , and an output end of the stirring motor 3 is connected to a stirring rod 4 via a coupling, and a plurality of stirring blades 5 are fixedly arranged on the surface of the stirring rod 4 .

[0049] Two sliding rods 6 are arranged inside the tank body 1 , and floating plates 61 are slidably connected to the surfaces of the two sliding rods 6 , and two connecting rods 14 are arranged on the surfaces of the floating plates 61 .

[0050] Floating board 61 can be airbag light

[0051] The top of the floating plate 61 is rotatably connected to two reset sleeves 7 , and reset rods 71 ​​are slidably connected inside the two reset sleeves 7 . Reset springs 72 are provided at one end of the two reset rods 71 ​​and are respectively located inside the two reset sleeves 7 .

[0052] The two reset sleeves 7 cooperate with the two reset rods 71 ​​and the two reset springs 72 so that the floating plate 61 below can continue to move upward when water is added.

[0053] The buoyancy of the floating plate 61 is greater than the elastic force of the return spring 72 .

[0054] A plurality of sealing grooves 8 are formed inside the tank body 1 , and sealing plates 9 are slidably connected inside the plurality of sealing grooves 8 .

[0055] The four sealing plates 9 are divided into two groups. One end of the two reset rods 71 ​​is rotatably connected to the bottom of the two sealing plates 9 , and one end of the two connecting rods 14 is rotatably connected to the bottom of the other two sealing plates 9 .

[0056] The other ends of the two reset sleeves 7 and the two connecting rods 14 are rotatably connected to the tops of the two floating plates 61 respectively.

[0057] After the medicine is added into the tank body 1 through a feeding pipe 10, when the medicine rises to contact the bottom of the floating plate 61, it pushes the floating plate 61 to move upward, thereby pushing one end of the two reset sleeves 7 to rotate to one side and move upward at the same time. When one end of the two reset sleeves 7 moves upward, it drives the other end to move and rotate to one side at the same time, thereby pushing the two sealing plates 9 to move to one side and merge inside the two sealing grooves 8 respectively, thereby sealing the feeding pipe 10.

[0058] When water is added to the interior of the tank body 1 through another feeding pipe 10, and when the water level rises, the two reset sleeves 7 are pushed to move upward, so that the two reset sleeves 7 respectively move upward on the surfaces of the two reset rods 71 ​​while squeezing the two reset springs 72. When the water level rises to contact the bottom of the other floating plate 61, it will push one end of the two connecting rods 14 to move upward and rotate to one side, so that the other end of the two connecting rods 14 pushes the two sealing plates 9 to seal the other feeding pipe 10, so that the amount of water and medicine added to the tank body 1 is one to one, so that the appropriate amount of medicine and water are added to the interior of the tank body 1 quickly and conveniently, and the stirring motor 3 is started to drive the stirring rod 4 connected to the multiple stirring blades 5 to rotate to one side, so as to facilitate the stirring and neutralization of the medicine and water added to the tank body 1.

[0059] When the liquid in the tank body 1 is pumped out, the two floating plates 61 will automatically drop and reset, thereby resetting the reset sleeve 7 and the connecting rod 14, so that the multiple sealing plates 9 will automatically move to one side and enter the multiple sealing grooves 8, and then the two feeding pipes 10 will open.

[0060] The working principle of the slurry modifier method for improving the dehydration effect of magnesium desulfurization byproducts provided by the present invention is as follows:

[0061] First, the total amount of slurry is estimated based on the diameter and liquid level of the absorption tower. In principle, the content of the reagent in the slurry should reach 6-12ppm;

[0062] The first addition must be made in a shock-like manner to increase the concentration of the agent in the slurry as quickly as possible. The amount of the agent can be appropriately increased according to the quality of the slurry.

[0063] When there is foam in the absorption tower, especially dark foam, as long as the foam does not overflow to the ground and cause environmental pollution, it is recommended to add it to the pit 30 minutes before each dehydration;

[0064] When the quality of the filter cake is very poor, add medicine to the underflow box of the cyclone station. The method is: fix a medicine adding barrel on the underflow box, drill a 4-5mm hole on the bottom of the side, prepare an empty medicine barrel, mix the medicine and water in a ratio of 1:1, add the medicine to the barrel after fully stirring, and start adding medicine by aiming at the observation hole of the underflow box. Generally, the filter cake begins to change after 2-3 minutes. The amount of medicine added can be fine-tuned according to the cake thickness. The medicine returns to the absorption tower with the filtrate, and after being stirred by the agitator of the absorption tower, it returns to the cyclone station with the slurry. This is a virtuous cycle, and the quality of the filter cake improves rapidly.

[0065] When the absorption tower foams seriously, the pit is used for simultaneous application. No dilution is required when adding the medicine in the pit. The dosage is added according to the foam situation on site to help the toxins in the absorption tower to be discharged with the slurry.

[0066] Track the filter cake quality every day. When it improves, reduce the dosage appropriately and enter the slurry activity recovery stage.

[0067] Check and observe the changes in the slurry every day, and fine-tune the dosage again according to the changes in the slurry circulation pump current and discharge port data;

[0068] When the quality of slurry and filter cake returns to normal, the cyclone station can stop adding drugs, but 1-3L of drugs should still be added to the pit every day to maintain the concentration of drugs in the absorption tower slurry, which is the slurry activity maintenance stage.

After the cyclone flow device adds the agent to the bottom flow, the dehydration effect is directly improved about two minutes later, the reaction is rapid, the effect is significant, the slurry is optimized, and the activity is improved. After the cyclone flow device improves the quality of the belt conveyor filter cake, the bottom flow filtrate of the belt conveyor is directly returned to the absorption tower through the byproduct, and the cycle is repeated in this way, so as to improve the quality of the slurry in the absorption tower, improve the activity of the slurry, form a virtuous cycle, reduce the expenditure on the use of agents, defoam and suppress foam, quickly detoxify, improve the quality of the slurry in the absorption tower, and quickly eliminate various bright and dark bubble reactions in the slurry in the absorption tower, improve the slurry environment in the absorption tower, and lay a foundation for a later virtuous cycle.
