Technical Field
[0001] The present invention relates to the technical field of waste heat recovery, and in particular to a mobile container heat energy mutual use slag smothering device and process. Background Art
[0002] The current slag smothering device uses a single silo for slag smothering work, and steps such as injecting water, smothering slag, draining water, discharging materials, and emptying the silo need to be carried out into the slag smothering container.
[0003] In view of the above related technologies, in the process of using a single silo for slag smothering, the following defects exist: after draining water, the temperature of the slag body drops suddenly, and the residual free calcium oxide will cause subsequent slow expansion due to insufficient reaction temperature, which will pose risks to the storage and use of the slag material. Summary of the Invention

Each slag smothering device includes a tipping car, and each tipping car is provided with a silo. Feeding ports are opened at the upper ends of the silos, and slag smothering covers for closing the feeding ports are rotatably connected to the upper ends of the silos. Vent pipes are communicated with the upper ends of the slag smothering covers, and each vent pipe is communicated with a first heat energy pipe. Connecting pipes are communicated with the lower ends of the tipping cars, and each connecting pipe is communicated with a second heat energy pipe. A heat transfer pipe is communicated between the second heat energy pipe on one tipping car and the first heat energy pipe on an adjacent tipping car, and a heat pump is arranged on the heat transfer pipe.
[0006] By adopting the above technical solution, first, the slag material is placed in one of the silos, then water is injected into the silo, and after the silo is sealed, slag smothering is carried out. After the slag smothering is completed, the water in the current silo is drained; at this time, slag material is put into the adjacent silo, then water is injected into the adjacent silo, and the adjacent silo is sealed. After the adjacent silo is filled with water, high-temperature water vapor is generated with the high-temperature slag. Under the action of the heat pump, the high-temperature water vapor is introduced into the drained silo through the heat transfer pipe to maintain the temperature of the slag body, accelerate the decomposition of the residual free calcium oxide, and further accelerate the pulverization of the slag body in the drained silo.
[0007] Optionally, each connecting pipe is communicated with a connecting pipe, the other end of each connecting pipe is connected with a water supply pipe, and a water supply valve is arranged on each water supply pipe.
[0008] By adopting the above technical solution, when water is supplied to the silo, the drain valve is controlled to close, the water supply valve is controlled to open, and then water can be supplied. After the water flows through the water supply pipe, it enters the silo from the lower end of the silo; the structure is simple and water injection is convenient.
[0009] Optionally, each of the connecting pipes is connected to a drain pipe, a drain pump is provided on each drain pipe, and a drain valve is provided on each drain pipe.
[0010] By adopting the above technical solution, when draining water, the water supply valve is controlled to close, the drain valve is opened, and then the drain pump is controlled to open. The water in the silo is discharged to the outside of the drain pipe through negative pressure. The structure is simple and drainage is convenient. The same connecting pipe is used for both water injection and drainage, which can save costs.
[0011] Optionally, a dust removal pipe is provided at the center of the circular track. A plurality of connecting pipes are rotatably connected to the dust removal pipe. The connecting pipes correspond to the silos one by one. Each connecting pipe is communicated with the ventilation pipe, and each connecting pipe is rotatably connected to the ventilation pipe.
[0012] By adopting the above technical solution, the dust and fumes generated during slag smothering are sucked into the dust removal pipe through negative pressure, and then the dust and fumes generated during the slag smothering stage are collected, which is highly convenient.
[0013] Optionally, the connecting pipe is also communicated with a sewage pipe, and a sewage valve for opening and closing the sewage pipe is provided on the sewage pipe.
[0014] By adopting the above technical solution, when discharging sewage, by controlling the sewage valve to open, the polluted impurities can be discharged to the outside through the sewage pipe through negative pressure.
[0015] In a second aspect, the present application provides a mobile container heat energy mutual use slag smothering process, adopting the following technical solution: The mobile container heat energy mutual use slag smothering process includes the following steps: S1: After a slag smothering device finishes slag smothering, control both the drain valve and the drain pump to open, and pump the water in the slag smothering device out of the silo; S2: Control another slag smothering device to inject water. After the water contacts the slag material in the silo, high-temperature water vapor is generated. Control the heat pump to open. The high-temperature water vapor enters the interior of the previous slag smothering device through the heat transfer pipe, accelerating the pulverization of the slag material in the previous slag smothering device; S3: Control the slag smothering device after draining to unload the material; S4: Repeat steps S1 - S3.
[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. First, place the slag material in one of the silos, then inject water into the silo. After sealing the silo, carry out slag smothering. After the slag smothering is completed, drain the water in the current silo; at this time, put the slag material into the adjacent silo, then inject water into the adjacent silo, seal the adjacent silo. After the adjacent silo is filled with water, high-temperature steam is generated with the high-temperature slag. Under the action of the heat pump, the high-temperature steam is passed through the heat transfer pipe into the silo that has drained water to maintain the temperature of its slag body, accelerate the decomposition of residual free calcium oxide, and further accelerate the pulverization of the slag body in the silo that has drained water.

Detailed Description of the Embodiment
[0020] The following further elaborates on this application in detail in conjunction with all the drawings.
[0021] The embodiment of this application discloses a mobile container heat energy mutual use slag smothering equipment.
[0022] Refer to Figure 1 and Figure 2 , the mobile container heat energy mutual use slag smothering equipment includes a circular track 1 and a number of slag smothering equipment 2 slidably connected to the track. Each slag smothering equipment 2 includes a tipping car 3. The lower end of each tipping car 3 is rotatably connected with a number of sliding wheels, and a number of sliding wheels can all roll on the circular track 1; each tipping car 3 is provided with a silo 4, and a feeding port is opened at the upper end of the silo 4. Refer to Figure 1 and Figure 2 , the upper end of the silo 4 is rotatably connected with a slag smothering cover 41 for closing the feeding port. The upper end of the slag smothering cover 41 is communicated with a ventilation pipe 42, and each ventilation pipe 42 is communicated with a heat energy pipe one 43. The lower end of the tipping car 3 is communicated with a connecting pipe 5, and each connecting pipe 5 is communicated with a heat energy pipe two 51. A heat transfer pipe 52 is communicated between the heat energy pipe two 51 on one tipping car 3 and the heat energy pipe one 43 on the adjacent tipping car 3, and a heat pump 53 is arranged on the heat transfer pipe 52.
[0023] Refer toFigure 1 and Figure 2 The bunker 4 includes bunker one 44 and bunker two 45. Bunker two 45 is adjacent to bunker one 44. First, open the slag smothering cover 41 of bunker one 44, then put the slag into bunker one 44, then cover the slag smothering cover 41, inject water into bunker one 44, and then slag smothering can be carried out.
[0024] Refer to Figure 1 and Figure 2 As shown in FIGS. and, a dust removal pipeline 11 is provided at the center of the circular track 1. A number of connecting pipes 5 are rotatably connected to the dust removal pipeline 11. The connecting pipes 5 correspond to the bunkers 4 one by one. Each connecting pipe 5 is communicated with a ventilation pipe 42, and each connecting pipe 5 is rotatably connected to the ventilation pipe 42. During the slag smothering process, the tipping car 3 can be manipulated to move, so as to feed the subsequent slag smothering equipment 2. If dust or dust impurities are generated during the slag smothering process, they are sucked into the dust removal pipeline 11 through negative pressure, so as to collect the dust and dust generated during the slag smothering stage, and the convenience is relatively high.
[0025] Refer to Figure 1 and Figure 2 After the slag smothering is completed, drain the water in bunker one 44, put the slag into bunker two 45, then cover the slag smothering cover 41, and let water flow through bunker two 45. After bunker two 45 is filled with water, high-temperature steam is generated with the high-temperature slag. Under the action of the heat pump 53, the high-temperature steam is passed into bunker one 44 through the heat transfer pipe 52 to maintain the temperature of the slag in bunker one 44, accelerate the decomposition of residual free calcium oxide, and thus accelerate the pulverization of the slag in bunker one 44.
[0026] Refer to Figure 1 and Figure 2 As shown in FIGS. and, each connecting pipe 5 is communicated with a connecting pipe 54, the other end of each connecting pipe 54 is connected with a water supply pipe 55, and a water supply valve 551 is provided on each water supply pipe 55. After manipulating the water supply valve 551 to open, water can be passed into the water supply pipe 55. Under the action of water pressure, the water flows through the water pipe into the connecting pipe 5 and enters bunker one 44 from the lower end of bunker one 44 to cool the slag in bunker one 44.
[0027] Refer to Figure 1 and Figure 2 By rotating the slag smothering cover 41 to cover bunker one 44, the slag smothering cover 41 and the bunker 4 are both connected by buckles, and a pressure relief valve is provided on the slag smothering cover 41. If it is detected that the pressure in the bunker 4 is too high, pressure relief can be carried out through the pressure relief valve to prevent danger caused by too high pressure in the bunker 4.
[0028] Refer to Figure 1 and Figure 2, each connecting pipe 5 is communicated with a drain pipe 56. A drainage pump is arranged on each drain pipe 56, and a drain valve 561 is arranged on each drain pipe 56. After the slag smothering of bin one 44 is completed, the drain valve 561 is manipulated to open, and then the drainage pump is manipulated to open. The water in the silo 4 is discharged outside the drain pipe 56 through negative pressure. The structure is simple and the drainage is convenient. The same connecting pipe 5 is used for both water injection and drainage, which can save costs.
[0029] Refer to Figure 1 and Figure 2 , the connecting pipe 5 is also communicated with a sewage pipe 6. A sewage valve 61 for opening and closing the sewage pipe 6 is arranged on the sewage pipe 6. In the middle and later stages of drainage, the drain valve 561 is manipulated to close, the work of the drainage pump is stopped, and then the sewage valve 61 is manipulated to open, and the residue at the bottom of the silo 4 is discharged outside the silo 4 through the sewage pipe 6.
[0030] Refer to Figure 1 and Figure 2 , after the residue is discharged, bin one 44 can be manipulated to move to the unloading point, and the slag in bin one 44 is discharged by using the tipping car 3.
[0031] The embodiment of the present application also discloses a mobile container heat energy mutual use slag smothering process.
[0032] The mobile container heat energy mutual use slag smothering process includes the following steps: S1: After a slag smothering device 2 finishes slag smothering, the drain valve 561 and the drainage pump are manipulated to open, and the water in the slag smothering device 2 is pumped outside the silo 4; S2: Manipulate another slag smothering device 2 to inject water. After the water contacts the slag in the silo 4, high-temperature water vapor is generated. Manipulate the heat pump 53 to open, and the high-temperature water vapor enters the interior of the previous slag smothering device 2 through the heat transfer pipe 52, accelerating the pulverization of the slag mass in the previous slag smothering device 2; S3: Manipulate the slag smothering device 2 after drainage to unload the material; S4: Repeat steps S1 - S3.
[0033] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
