[0021] A support plate 5 is provided at the lower part of the tower body 1. The support plate 5 is conical, and a support column 6 is fixed in the middle of the support plate 5. A support frame is provided above the support plate 5 on the tower body 1. The support frame includes a frame body 7 and a support tube 8 provided on the upper part of the frame body 7. The support tube 8 is sleeved on the support column 6, so that the support frame is placed in the tower body 1 and the position is fixed. In order to fix the support frame, an external thread is provided at the lower part of the support column 6, and an internal thread matching the external thread is provided at the lower part of the support tube 8, so that the support tube 8 can be threadedly connected with the support column 6, so that the support frame is more stable in the tower body 1.

[0022] A cavity 25 is also provided on the side wall of the tower body 1, and a water guide hole 11 is provided on the inner wall of the tower body 1 located above the support plate 5, which connects the cavity 25 with the inner wall of the tower body 1.

An exhaust fan 13 and a blower 14 connected to the airbag 9 are also fixed on the tower body 1, and the exhaust fan 13 can extract the gas in the tower body 1, and the blower 14 can add gas to the airbag 9. Moreover, since the outer ring of the airbag 9 is fixed to the cavity 25, the airbag 9 expands toward the inside of the tower body 1 when the gas is blown in, so that the protrusions are inserted into the water guide hole 11.

[0023] The steam generator 15 is also included. The steam generator 15 is connected to an air duct 16. One end of the air duct 16 passes through the tower body 1 and the support plate 5 and is connected to the upper part of the tower body 1. One end of the air duct 16 located in the tower body 1 is a curved pipe with an opening downward, which can prevent the solution in the upper part of the tower body 1 from entering the air duct 16 during spraying.

[0024] The upper part of the right side of the tower body 1 is also connected to a pressure relief hole, and the pressure relief hole is connected to a pressure relief pipe 17, and the right end of the pressure relief pipe 17 is closed. A slide plate 18 is connected to the pressure relief pipe 17 in a transverse sliding manner, and a spring is provided between the right side of the slide plate 18 and the right end of the pressure relief pipe 17. In this embodiment, the spring is a compression spring, and the specific model is selected according to actual needs. An air guide hole 20 is provided on the right side of the slide plate 18 on the pressure relief pipe 17; a control part 19 for controlling the steam generator 15 to be turned off is provided on the inner side of the right end of the pressure relief pipe 17. When the slide plate 18 presses the control part 19, the steam generator 15 can stop introducing steam into the tower body 1.

[0025] A push rod 21 is also fixed on the right side of the slide plate 18. The push rod 21 passes through the right end of the pressure relief pipe 17, and the push rod 21 is connected to the pressure relief pipe 17 in a transverse sliding manner. The right end of the push rod 21 is opposite to the switch 22 of the exhaust fan 13. When the push rod 21 moves to the right, it gradually approaches the switch 22 of the exhaust fan 13 until the push rod 21 presses the switch 22 and turns on the switch 22, so that the exhaust fan 13 can be started.

[0026] The inner wall of the tower body 1 is provided with a water outlet 12 connecting the cavity 25 and the inside of the tower body 1 below the support plate 5, and a fluorine element detector is provided in the tower body 1 below the support plate 5. The bottom of the tower body 1 is provided with a lead-out hole 23 for leading out the solution, and a sealing plug 24 is provided in the lead-out hole 23.

[0027] The specific implementation process is as follows:

[0028] The support frame is placed in the tower body 1, and a fixed amount of coal is added into the tower body 1. The tower body 1 is then sealed with the cover body 2, and the blower 14 is started to blow gas into the airbag 9, thereby causing the gas to expand and drive the protrusion to be inserted into the water guide hole 11 until the protrusion closes the water guide hole 11.

[0029] Then start the spray mechanism and the steam generator 15, so that the spray mechanism adds the solution into the tower body 1, and the steam generator 15 adds steam into the tower body 1. The solution is sprayed on the coal through the water inlet pipe 3 and the spray head 4 until the solution is added in an appropriate proportion to the coal, and then the spray mechanism is closed. After the solution enters the tower body 1, it soaks the coal. At the same time, steam is added into the tower body 1, so that the solution generates bubbles and the solution is heated up, so that the fluorine element in the coal can be dissolved out faster.

[0030] As the steam enters the tower body 1, the pressure on the upper part of the tower body 1 at the support plate 5 gradually increases, so that the gas enters the pressure relief pipe 17 through the pressure relief hole to relieve the pressure. After the gas enters the pressure relief pipe 17, it pushes the slide plate 18 to move to the right until the slide plate 18 contacts the control member 19, which will shut down the steam generator 15 and stop adding steam to the tower body 1. When the slide plate 18 slides over the air guide hole 20, the pressure can be relieved through the air guide hole 20.

[0031] When the slide plate 18 slides to the right, the push rod 21 will be driven to move to the right, thereby gradually approaching the switch 22 of the exhaust fan 13, until the push rod 21 contacts the switch 22 of the exhaust fan 13, and presses the switch 22 of the exhaust fan 13, so that the exhaust fan 13 is operated, the gas in the air bag 9 is extracted, and the protrusion 10 exits the water guide hole 11. At this time, the solution containing the fluorine element in the coal in the upper part of the tower body 1 will enter the cavity 25 through the water guide hole 11, and then be introduced into the lower part of the tower body 1 through the water outlet hole 12, and be detected by the fluorine element detection instrument to determine whether the fluorine element in the coal exceeds the standard and whether the exhaust gas will affect the environment during combustion.

[0032] After the test is completed, the cover 2 is opened and the support frame is taken out. When the test is taken out, the tested coal will be taken out with it, which is convenient for the next test. The solution remaining in the lower part of the tower body 1 can be discharged from the outlet hole 23 by opening the sealing plug 24.
