[0030] In the present invention, the height of the spray tank 18 in the slag stewing tank 1 is higher than the upper height of the slag stewing box 39.

[0031] In the present invention, the steam pressure control tank 9 , the steam exhaust pipe 10 and the steam pipe 7 all pass through the dust cover 3 .

[0032] In the present invention, the dust removal cooling box is installed between the extraction pump 1 and the extraction pump 25, and the extraction pump 25 is close to the water tank 23.

[0033] In the present invention, the water pipe 6 is divided into a steel pipe 1 and a hose 1. The hose 1 is from the end of the pump 21 close to the slag stewing tank 2 to the end of the water pipe 6, and the steel pipe 1 is from the end of the pump 21 close to the slag stewing tank 2 to the water tank 23.

[0034] In the present invention, the water inlet pipe is hose 2.

[0035] In the present invention, the cooling system is an existing cooling system.

[0036] In the present invention, the slag stewing tank 1 and the slag stewing tank 2 2 can also be slag stewing pools, and the slag stewing tank 2 2 can be set in multiple numbers, and steam connecting pipes (that is, the steam pipe 7 in the present invention) are arranged between adjacent multiple slag stewing tanks 2.

[0037] In the present invention, when the speed at which the steam in the slag stewing tank 2 is transported to the dust reduction pipe 8 is slow, the staff can open the valve 11 according to the on-site conditions to allow the steam to enter the dust reduction pipe 8 through the steam exhaust pipe 10.

[0038] The workflow of the present invention is: The staff pours the high-temperature steel slag into the slag box 39 of slag pot 1 and the slag box 39 of slag pot 2. The staff turns on the servo motor 33 through the controller. The servo motor 33 drives the ball screw 38 to rotate, so that the slag box 39 falls to a suitable position along the guide rail 42, that is, the upper height of the slag box 39 is lower than the upper height of the slag pot 1 or the slag pot 2. The servo motor 33 is turned off, and the pushing cylinder 1 and the pushing cylinder 3 are turned on. The pushing cylinder 1 drives the baffle 1 to move in the direction close to the pushing cylinder 1, and the pushing cylinder 3 drives the baffle 2 to move in the direction close to the pushing cylinder 3. After the baffle 2 and the baffle 1 move to the suitable position, that is, the through hole 1 and the through hole 6 are exposed, the pushing cylinder 1 and the pushing cylinder 3 are turned off, and the pushing cylinder 2 is turned off. The pushing cylinder 2 drives the water pipe 6 to cooperate with the through hole 1 and the through hole 6, and the protrusion 1 and the groove 1 cooperate.

[0039] Open cylinder 1 4, which drives the dust cover 3 to move downward until the sealing protrusion 36 below the dust cover 3 cooperates with the sealing groove 41 of the slag pot 1 or the slag pot 2, and the serration 1 of the sealing member 35 cooperates with the serration 2 of the sealing plate 34, close cylinder 1 4, open cylinder 2 19, which pushes the spray pipe 18 to move away from cylinder 2 19 until multiple nozzles enter the slag pot 1 and are above the slag box 39 in the slag pot 1, close cylinder 2 19, open pump 3 22, and the water in the water tank 23 enters the spray pipe 18 through the water inlet pipe, and then enters the slag box 39 of the slag pot 1.

[0040] After spraying for a period of time, turn off pump three 22 and turn on cylinder two 19. Cylinder two 19 drives the spray pipe 18 to move towards cylinder two 19 until the spray pipe 18 returns to the initial position. The steel slag in the slag box 39 of the slag tank one 1 continuously generates steam after contacting water. After a period of time, turn on valve four 17, pump two 21 and the two-way pump. The water in the water tank 23 enters the slag box 39 of the slag tank two 2 through the water pipe 6. After a period of time, turn off valve four 17, pump two 21, valve five and the two-way pump. Turn on the two-way pump and valve five. The two-way pump draws the retained water in the water pipe 6 into the water tank 23. Turn off the two-way pump and valve five.

[0041] At the same time, the steel slag in the slag box 39 in the slag tank 1 generates steam. The pressure sensor in the slag tank 1 detects the pressure value and transmits it to the controller. The controller compares the pressure value with the set value. When the pressure value is exceeded, the controller opens the pressure control valve 12, valve 15, valve 3 16 and pump 14 on the steam pressure control pipe 9 of the slag tank 1. A small part of the steam in the slag tank 1 enters the dust removal pipe 8 through the steam pressure control pipe 9, and a large part enters the steam pipe 7, and then enters the slag box 39 in the slag tank 2.

[0042] Since the slag stewing tank 1 generates steam first, the steam in the slag stewing tank 1 enters the slag stewing tank 2 through the steam pipe 7, and the steam applies force to the steel slag in the slag stewing box 39 in the slag stewing tank 2. The steel slag in the slag stewing box 39 in the slag stewing tank 2 will produce upward steam due to contact with water, so that the two parts of steam collide in the steel slag, causing the steel slag to be crushed. The pressure sensor in the slag stewing tank 2 senses the pressure value of the slag stewing tank 2 and transmits it to the controller. The controller compares it, and when the pressure value exceeds the pressure value, opens the pressure control valve 12 on the steam pressure control pipe 9 of the slag stewing tank 2, and the steam in the slag stewing tank 2 enters the dust removal pipe 8 through the steam pressure control pipe 9.

[0043] The temperature sensor in the slag stewing tank 1 senses the temperature in the slag stewing tank 1 and transmits it to the controller. The temperature sensor in the slag stewing tank 2 senses the temperature in the slag stewing tank 2 and transmits it to the controller. If the temperature value is lower than the set value, the pressure control valve 12 on the steam pressure control pipe 9 of the slag stewing tank 1 or the slag stewing tank 2 is fully opened, so that the steam in the slag stewing tank 1 or the slag stewing tank 2 enters the dust removal pipe 8 through the steam pressure control pipe 9. After a period of time, the pressure control valve on the steam pressure control pipe 9 of the slag stewing tank 1 is closed. 12. The pressure control valve 12, valve 2 15, valve 3 16 and pump 14 on the steam pressure control pipe 9 of the slag stewing tank 2 are turned on to open the extraction pump 1 in the dust removal pipe 8 to extract the steam in the dust removal pipe 8 into the dust removal cooling box. The steam first passes through the cooling zone (the cooling system is turned on in advance, and cooling water is introduced into the cooling water pipe) to become water. The water enters the dust reduction zone through the through hole 4 of the partition plate. After the activated carbon adsorbs the water for a period of time, the extraction pump 2 25 is turned on to extract the water into the water tank 23 through the extraction pump 2 25.

[0044] Open push cylinder 2 to separate the end of water pipe 6 from through hole 1 and through hole 6, close push cylinder 2, push cylinder 1 and push cylinder 3 at the same time, so that baffle 1 blocks through hole 1 and baffle 2 blocks through hole 6, open cylinder 1 4, cylinder 1 4 drives dust cover 3 to move upward, after moving to the appropriate position, close cylinder 1 4, open servo motor 33, servo motor 33 drives slag box 39 to move upward, after moving to the appropriate position, close servo motor 33, and the staff takes out the slag after slag stewing.

[0045] In the present invention, when steam passes through the filter box 26, the steel slag powder carried away in the steam of the filter plate 30 can remain on the side of the filter plate 30 close to the slag stewing tank 1. After a period of time, the staff can turn on the cylinder three 31 through the controller. The cylinder three 31 pushes the scraper 27 to move along the side of the filter plate 30, and the steel slag powder remaining on the filter plate 30 is cleaned into the collecting piece 29. The cylinder three 31 drives the scraper 27 to return to the initial position. The staff can take the collecting piece 29 out of the connecting piece 28 and pour out the steel slag powder in the collecting piece 29.

[0046] In the present invention, the cylinder 437 pushes the adjustment plate 40 to adjust the width of the slag box 39 so that the steel slag in the slag box 39 can contact the steam discharged from the steam pipe 7 in advance.

[0047] The above workflow can be automatically controlled by the controller.
