Description

Technical Field

[0001] The invention relates to the technical field of slag treatment, and in particular to a slag water quenching system and a slag water quenching method. Background Art

[0002] Hazardous solid waste contains a certain amount of valuable metals (such as copper), which can be recovered through smelting. At the same time, the hazardous solid waste is also rendered harmless, killing two birds with one stone. In the process of treatment, slag will be formed after smelting. The slag needs to be quenched with water to form smaller sand-like particles (i.e., water quenching granulation treatment) to facilitate subsequent comprehensive utilization (such as as a building material). Slag water quenching is generally carried out in a water quenching box, which specifically includes: putting the high-temperature slag to be treated into the water quenching box, and then spraying cold water into the water quenching box to impact it. During the process, the slag will be granulated into small particles and cooled, and finally the slag will be discharged from the water quenching box to obtain the water-quenched granulated slag. In the specific treatment process, a large amount of water is often consumed, resulting in serious waste of water resources. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a slag water quenching system, which solves the problem in the prior art that the slag water quenching consumes a large amount of water and causes serious waste of water resources.

[0004] According to an embodiment of the present invention, a slag water quenching system includes a water quenching pool and a discharge pool, and a material cart that moves back and forth between the water quenching pool and the discharge pool, wherein the moving trajectory of the material cart is inclined and the lower end is located in the water quenching pool, and the higher end is located in the discharge pool, and an overflow pipe is also installed on the water quenching pool; the material cart includes an outer shell with openings on both the upper and lower parts, a rotating mounting shaft is fixedly connected in the outer shell, a flap plate that can open or close the opening at the lower end of the outer shell is rotatably sleeved on the rotating mounting shaft, and a plurality of filter holes are opened on the flap plate; an installation plate is also installed above the water quenching pool, a plurality of first nozzles are installed on the installation plate to spray water downward, and a plurality of second nozzles are also installed on the installation plate to spray high-pressure air downward.

[0005] In the above embodiment, the slag is first thrown into the water quenching pool for rapid cooling, and then carried with the material truck to the top of the water quenching pool for spraying water. Both processes are water quenched and granulated, and the sprayed water flows downward into the water quenching pool for the next round of use. After spraying water, high-pressure air continues to be sprayed to quickly drain the water on the surface of the slag. The water produced by drainage also flows to the water quenching pool below without being wasted. This improves the utilization rate of water resources and solves the problem of large water consumption in slag water quenching in the prior art, which leads to serious waste of water resources.

[0006] Furthermore, a support rod is fixedly connected to the outer shell and is located obliquely above the rotating mounting shaft. The flip plate includes an arc plate section and a straight plate section. The straight plate section is rotatably mounted on the rotating mounting shaft through a mounting sleeve. During the rotation of the flip plate, the arc plate section can be in contact with or away from the support rod above the support rod.

[0007] Furthermore, a cover plate is fixedly connected to the inner wall of the shell, and during the rotation of the flip plate, the straight plate section can be in contact with or away from the cover plate at an angle below the cover plate, and the end of the straight plate section can move to the bottom of the shell.

[0008] Furthermore, a first connecting plate is fixedly connected to the upper end of the shell, a second connecting plate is fixedly connected to the end of the arc plate segment, and it also includes a pair of first winches and a pair of second winches, a first cable is respectively connected between the two first winches and the two ends of the first connecting plate, and a second cable is respectively connected between the two second winches and the two ends of the second connecting plate.

[0009] Furthermore, the bottom of the water quenching tank is a funnel structure, and a conveying pipe is fixedly connected to the lower end, and a conveying screw is arranged in the conveying pipe.

[0010] Furthermore, side plates are fixedly connected to both sides of the straight plate segment and the arc plate segment to form a groove-shaped structure.

[0011] Furthermore, a plurality of third nozzles are installed in the water quenching pool and are located below the lower end of the moving track to spray high-pressure air upwards. A compressor is also provided outside the water quenching pool to supply compressed air to the third nozzles.

[0012] Furthermore, a plurality of installation pipes are fixedly installed in the water quenching tank, a plurality of third nozzles are respectively installed on each installation pipe, and all the installation pipes are connected to the air compressor.

[0013] Furthermore, a pair of inclined tracks for the material vehicle to move are fixedly arranged between the water quenching tank and the discharge tank, and wheels respectively rollingly matched with the two tracks are installed on both sides of the lower end of the shell.

[0014] According to an embodiment, a slag water quenching method is also provided, which is performed using the above-mentioned slag water quenching system and includes the following steps:

[0015] Put the slag into the material car and immerse it in water. Then move the material car diagonally upward to make the slag exposed to the water surface. Start the first nozzle to spray water to the slag to reduce the surface temperature of the slag to below 95-100℃. Stop spraying water and start the second spray to spray high-pressure air to the slag to quickly drain the water on the slag surface. Then continue to move the material car diagonally upward to place the slag into the discharge pool and discharge it through the discharge pool.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The slag is first put into the water in the water quenching pool for rapid cooling, and then moved above the water surface for water spraying to fully granulate the slag. The sprayed water in the process flows downward into the water quenching pool for the next round of use. After spraying water, high-pressure air continues to be sprayed to quickly drain the water on the surface of the slag. The water produced by drainage also flows to the water quenching pool below without being wasted. This improves the utilization rate of water resources to a limited extent, solves the problem of large water consumption of slag water quenching in the prior art, resulting in serious water resource waste, and also reduces the overall energy consumption of slag water quenching treatment.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] In an exemplary embodiment, Figure 1-7 As shown, this embodiment provides a slag water quenching system, which includes a water quenching pool 1 and a discharge pool 2, and a material car that moves back and forth between the water quenching pool 1 and the discharge pool 2. A pair of inclined tracks 4 for the material car to move are fixedly arranged between the water quenching pool 1 and the discharge pool 2. The material car includes a shell 5, and wheels 6 are installed on both sides of the lower end of the shell 5 and are respectively matched with the two tracks 4 for rolling. The lower end of the track 4 is located in the water quenching pool 1, and the upper end is located in the discharge pool 2, that is, the moving track of the material car is inclined and the lower end is located in the water quenching pool 1, and the upper end is located in the discharge pool 2. An overflow pipe 7 is also installed on the water quenching pool 1, and a pair of inclined tracks 4 are fixedly arranged between the water quenching pool 1 and the discharge pool 2. A common wall 8 is arranged, and the overflow pipe 7 is arranged at a position lower than the upper end surface of the common wall 8. When the water in the water quenching pool 1 becomes more, it flows out through the overflow pipe 7, thus preventing the water from entering the discharge pool 2; the material car includes a shell 5 with openings at the top and bottom, and a rotating mounting shaft 9 is fixedly connected to the shell 5. A flip plate 10 that can open or close the lower end opening of the shell 5 is rotatably sleeved on the rotating mounting shaft 9, and a plurality of filter holes (not shown) are opened on the flip plate 10; a mounting plate 11 is also installed above the water quenching pool 1, and a plurality of first nozzles 12 are installed on the mounting plate 11 to spray water downward, and a plurality of second nozzles 13 are also installed on the mounting plate 11 to spray high-pressure air downward.

[0030] like Figure 1-7As shown, at the same time, a slag water quenching method using the above-mentioned slag water quenching system is also provided. Specifically, there is water in the water quenching pool 1, and the lower end of the shell 5 is open, so that water can enter the shell 5. At the same time, a filtering hole is provided on the flip plate 10, and a movable gap is also left between the flip plate 10 and the inner wall of the shell 5, so that water can also pass above the flip plate 10, so the water surface in the shell 5 is level with that in the water quenching pool 1. At the beginning of the water quenching, the material car is located at the lowest point of the track 4, and the upper end surface of the shell 5 is located above the water surface, so that the slag can be thrown into the material car in the water quenching pool 1 first. After the material is fed once, the material cart moves upward obliquely so that the flip plate 10 moves above the liquid level of the water quenching pool 1, and then the first nozzle 12 is started to further spray water on the slag on the flip plate 10. In the above two processes, the slag is water-quenched and granulated. During the rapid cooling, a large amount of water vapor will be generated, so the liquid level in the water quenching pool 1 will drop. In a process, the sprayed water will flow downward to the water quenching pool 1 for replenishment to ensure that the next round of water quenching is carried out normally. Furthermore, the water sprayed by the first nozzle 12 has a certain pressure, such as 2.5kg / cm 2 or higher, so as to disperse the porous structure formed by water quenching into particles, and at the same time, spray water through the first nozzle 12 to reduce the surface temperature of the slag to 95-100°C (the temperature can be detected by an infrared temperature detector), and then stop the first nozzle 12 from spraying water, and start the second nozzle 13 to continue spraying high-pressure air after stopping the water spraying, which can be carried out for 8-10 minutes, so that the water on the surface of the slag can be quickly drained, and at the same time, the water generated by the drainage also flows into the water quenching pool 1 below, and is not wasted. Finally, the material car continues to move upward to the discharge pool 2, and the flip plate 10 rotates to open the opening at the lower end of the shell 5 to introduce the granulated slag into the discharge pool 2, and finally it can be discharged through the discharge pool 2, which improves the utilization rate of water resources and solves the problem of large water consumption of slag water quenching in the prior art, resulting in serious waste of water resources;

[0031] In a further solution, a plurality of mounting pipes 14 are installed in the water quenching pool 1 below the lower end of the track 4, and a plurality of third nozzles 15 are installed on each mounting pipe 14 to spray high-pressure air upward. A compressor for supplying compressed air to the third nozzles 15 is also provided outside the water quenching pool 1, and the high-pressure air is introduced into the mounting pipes 14 through the compressor (similarly, a compressor for supplying high-pressure air to the second nozzles 13 is also provided accordingly), and then sprayed upward through the third nozzles 15, and at this time, the material car is just above all the third nozzles 15. After the high-pressure air enters the water, the water flow will accelerate upward, and the high temperature of the slag will make the water in the material car in a violent rolling state, so that the water quenching The granulation is more intense and the effect is better; at the same time, the upper end of the material car is higher, above the water surface, and the rolling water and slag will not jump out of the material car; in particular, in this scheme, two water quenching treatments are actually carried out, respectively under the water surface in the water quenching pool 1 and on the water surface in the water quenching pool 1, ensuring the water quenching granulation effect while saving water resources; in another scheme, one of the mounting pipes 14 can be replaced with a water inlet pipe 37 (or a water inlet pipe 37 located at the bottom of the water extraction pool can be set up, and water can be continuously added to the water quenching pool 1 through the water inlet pipe 37, so that the water will not be reduced due to the large amount of steam generated during water quenching, and cooperate with the high-pressure air introduced through the third nozzle 15 to make the first water quenching efficient). In more detail, in this scheme, the slag after the second water quenching and draining is still at a relatively high temperature, which can be between 90-95°C. After a period of time at this temperature, the moisture inside the slag can be evaporated, and eventually the moisture content of the slag is reduced to 10-15% (if necessary, subsequent drying can be continued to further reduce the content, but at such an initial moisture content, the energy consumption required for subsequent drying will also be reduced accordingly, so the overall energy consumption can also be controlled).

[0032] like Figure 1-3As shown, in a further scheme, during the water quenching process, some slag generated during the water quenching process will pass through the filter holes on the flip plate 10 and fall to the bottom of the water quenching pool 1. The bottom of the water quenching pool 1 in this scheme is a funnel structure, and a conveying pipe 16 is fixedly connected to the lower end. A conveying screw 17 is arranged in the conveying pipe 16, and a driving motor 18 for driving the conveying screw 17 to rotate is also arranged outside the conveying pipe 16. In this way, the slag that falls to the bottom can be easily exported. These slags can be used as raw materials of the front process and mixed with hazardous solid waste to make bricks, and then put into the smelting furnace for smelting without being discharged. At the same time, the amount of auxiliary materials purchased in the front process is also reduced (auxiliary materials need to be mixed to make bricks during smelting, and then put into the smelting furnace for smelting), so as to achieve the effect of reducing costs and increasing efficiency, and at the same time avoid the problem of environmental pollution caused by the discharge of waste slag. In further detail, the export of the bottom slag is generally carried out regularly according to the accumulation situation. When it is necessary to export, the upper water is first pumped out by a pump body, and then exported. After exporting, the water quenching pool 1 can also be cleaned.

[0033] like Figure 1-7As shown in the more detailed scheme, a mounting platform 19 is fixedly arranged beside the discharge pool 2, on which a pair of first winches 20 and a pair of second winches 21 are installed. The two first winches 20 and the two second winches 21 are connected to the housing 5 and the flip plate 10 through the first cable 22 and the second cable 23 respectively. The first winch 20 pulls the material cart upward through the first cable 22. After the first cable 22 is unwound, the material cart moves obliquely downward by its own weight to smoothly return to the water quenching pool 1, ensuring that the next round of processing is carried out smoothly, and further In addition, a through hole (not shown) can also be provided on the side wall of the shell 5, so that water can pass smoothly during the movement of the material cart, so that the movement of the material cart is smoother; the connection between the first cable 22 and the material cart and the connection between the second cable 23 and the flip plate 10 are respectively located on both sides of the rotating installation shaft 9, and the second winch 21 is also continuously running during the operation of the first winch 20, which can assist the material cart to move smoothly. At the same time, the second winch 21 also pulls the flip plate 10 to make it smoothly in the shell 5 Rotate to realize the introduction of slag into the discharge pool 2; in further detail, a support rod 24 located obliquely above the rotating mounting shaft 9 is also fixedly connected in the shell 5, and the flip plate 10 includes an arc plate section 25 and a straight plate section 26. The straight plate section 26 is rotatably sleeved with the rotating mounting shaft 9 through a mounting sleeve 27. During the rotation of the flip plate 10, the arc plate section 25 can be in contact with or away from the support rod 24 above the support rod 24. The flip plate 10 is an arc-shaped structure as a whole, and the arc plate section 25 is close to the lower end of the track 4, so that the center of the flip plate 10 is in the process of moving the material car. The second cable 23 and the rotating mounting shaft 9 are used to make the flip plate 10 relatively stable during the movement (stable relative to the shell 5). When the slag needs to be discharged, the second cable 23 is wound to make the arc plate section 25 move obliquely upward and the straight plate section 26 move obliquely downward, so that the slag falls from the gap between the lower end of the straight plate section 26 and the lower end of the shell 5 and is discharged smoothly.

[0034] In a further solution, a first connecting plate 39 is fixedly connected to the upper end of the outer shell 5, a second connecting plate 40 is fixedly connected to the end of the arc plate segment 25, a first cable 22 is connected between the two first winches 20 and the two ends of the first connecting plate 39, and a second cable 23 is connected between the two second winches 21 and the two ends of the second connecting plate 40, so that pulling can be performed from both sides, which is smoother.

[0035] like Figure 1-7As shown in the further detailed scheme, a gap is left between the end of the straight plate section 26 and the shell 5 to ensure smooth rotation, and a cover plate 28 is fixedly connected to the inner wall of the shell 5. During the rotation of the flip plate 10, the straight plate section 26 can be in contact with or separated from the cover plate 28 at an angle below the cover plate 28. The cover plate 28 blocks the gap between the end of the straight plate section 26 and the shell 5, and also cooperates with the support rod 24, the rotating mounting shaft 9 and the second cable 23 to make the flip plate 10 relatively more stable, and also ensures that the end of the straight plate section 26 can be smoothly moved to the bottom of the shell 5; in a further embodiment, the provided flip plate 10 can also be a groove-shaped structure. The structure is that side plates 41 are fixedly connected on both sides of the arc plate segment 25 and the straight plate segment 26 to enclose a groove-like structure, and a gap is left between the two side plates 41 and the inner wall of the shell 5 to ensure normal rotation, and the slag can fall into the groove-like structure to avoid being stuck in the gaps on both sides; in further detail, the cover plate 28 can be inclined, and the higher end is fixedly connected to the inner wall of the shell 5, and the end of the straight plate segment 26 is against the lower wall of the lower end. Part of the slag may fall on the cover plate 28 during the downward falling process. When the slag is subsequently discharged, this part can also slide down more smoothly when the straight plate segment 26 is downward, and the discharge is more thorough.

[0036] like Figure 1-7 As shown, in a further scheme, both ends of the mounting plate 11 are fixedly connected with support plates 29, and the two support plates 29 are fixedly connected to the water quenching pool 1 respectively, so as to fix the mounting plate 11 above the water quenching pool 1, and the first cable 22 and the second cable 23 and the material car can pass through between the two support plates 29 and under the mounting plate 11 without interfering with each other, and the first nozzle 12 and the second nozzle 13 are installed on the lower plate surface of the mounting plate 11 (the first nozzle 12 and the second nozzle 13 can be installed through different pipelines, and they can be arranged alternately, but not at the same time during operation, so as not to affect each other, and both can cover the slag in the flip plate 10 below to the greatest extent), and a water supply tank 30, a water pump 31, etc. can be installed on the upper plate surface to ensure the water supply of the first nozzle 12, and an air compressor can also be installed to ensure the air supply of the second nozzle 13.

[0037] like Figure 1-7As shown, in this scheme, when feeding, the slag falls from between the two tracks 4 onto the flip plate 10 in the material car. During the process, it does not contact the inner walls on both sides of the material car (that is, the slag does not contact the inner wall of the shell 5), nor does it contact the two first cables 22 and the second cables 23. In a further scheme, an inclined plate 38 is fixedly connected to the inner wall of the water quenching tank 1, and when the material car is at the lowest position on the track 4, the inclined plate 38 is located directly above the lower side of the material car and tilted toward the inside of the material car. When the slag falls, the inclined plate 38 can play a blocking role to prevent the slag from accidentally falling on the lower side inner wall of the material car, while the inner wall of the higher side is farther away and will not contact the slag.

[0038] like Figure 1-7 As shown, further, a first baffle 32 located directly below the inclined plate 38 is fixedly connected to the upper end of the inner wall of the water quenching tank 1 near the lower end of the track 4, and the shell 5 can abut against the first baffle 32 when it is at the lowest point of the track 4, so that the material cart is more stable during the feeding process; similarly, a second baffle 33 is fixedly connected to the inner wall of the discharge tank 2 near the higher end of the track 4, and the shell 5 can abut against the second baffle 33 when it is at the highest point of the track 4, so that the material cart is more stable during the discharge process; in more detail, the second baffle 33 includes a horizontal plate 34 fixedly connected to the inner wall of the discharge tank 2 and a vertical plate 35 fixedly connected to the horizontal plate 34, and the vertical plate 35 can abut against the shell 5, The horizontal plate 34 partially covers the top of the discharge pool 2, and an exhaust fan 36 can be installed on the horizontal plate 34 to extract the water vapor generated in the discharge pool 2 below (the residual heat will generate water vapor when the slag falls into the discharge pool 2 below after granulation, and the water vapor will move upward in the discharge pool 2). In this way, a mounting platform 19 can be set next to the horizontal plate 34 for the installation of the first winch 20 and the second winch 21, and prevent the water vapor from causing adverse effects on them; in a more detailed scheme, a water vapor recovery device can also be set above the water quenching pool 1 to collect the water vapor for reuse (such as using the residual heat of the water vapor to preheat the cold water), while also preventing the water vapor from spreading everywhere.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
