If it is dumped at will, it will inevitably damage the ecological environment. At present, the main methods for treating industrial waste salt are landfill, incineration and harmless comprehensive utilization. Among them, the landfill method requires a large amount of space, and the waste salt may penetrate into the underground soil layer and endanger the groundwater system, so this treatment method is a temporary expedient; the incineration method will cause the problem of inorganic salt melting. The molten inorganic salt will cause strong corrosion to the equipment, often blocking the pipeline and paralyzing the equipment. The entrainment of inorganic salts in its flue gas is also serious, and its flue gas needs to be specially treated. Therefore, the incineration treatment method is technically difficult, costly and not often used; harmless comprehensive utilization is the direction of industrial waste salt treatment in the future.

[0045] Furthermore, the air distribution assembly 800 includes a lower air distribution plate 804 connected to the tower body 103, an upper air distribution plate 802 is connected to the tower body 103 above the lower air distribution plate 804, a plurality of threaded holes 802b are arranged on the upper air distribution plate 802, a through hole 802c connected to the air chamber 103e is opened on the upper air distribution plate 802 below the threaded hole 802b, the upper air distribution plate 802 is threadedly connected to a hood 801 having a downward hollow cavity 801a through the threaded hole 802b, and a plurality of air holes 801b are arranged on the hood 801 above the upper air distribution plate 802 A wind chamber 103e is formed between the lower side of the upper air distribution plate 802, the inner wall of the tower body 103 and the upper side of the lower air distribution plate 804, a plurality of upper slag discharge holes 802a are arranged on the upper air distribution plate 802, a plurality of slag discharge pipes 803 corresponding to the upper slag discharge holes 802a are arranged between the upper air distribution plate 802 and the lower air distribution plate 804, and lower slag discharge holes 804a are provided on the lower air distribution plate 804 at the lower side of the slag discharge pipes 803. When the first air inlet control valve 102 is opened, the first air inlet pipe 101 is connected to the wind chamber 103e, and the axis of the air hole 801b is inclined upward from the inside to the outside.

[0046] A liquid ventilation ring 200 is connected to the tower body 103 above the air distribution assembly 800. The outer edge of the liquid ventilation ring 200 is a curved surface 202 that is recessed toward the center of the liquid ventilation ring 200. The outer edges of the upper and lower ends of the liquid ventilation ring 200 are fitted to the inner wall of the tower body 103 to form a closed liquid and air inlet channel between the curved surface 202 and the inner wall of the tower body 103. A plurality of atomizing nozzles 201 are arranged on the liquid ventilation ring 200. The liquid and air inlet channels are connected to the inner cavity 103c via the atomizing nozzles 201, and the liquid inlet pipe 104 can be connected to the liquid and air inlet channels.

[0047] A temperature sensor 400 is connected to the tower body 103 above the upper air distribution plate 802; in the initial state, all control valves are in a closed state; when removing organic matter from high-salinity wastewater, the first air inlet control valve 102 is opened, and high-temperature gas is introduced into the first air inlet pipe 101, and the external high-temperature air enters the wind chamber 103e through the first air inlet control valve 102. The temperature is measured by the temperature sensor 400, and the air inlet temperature is controlled between 500°C and 700°C according to different working conditions. Pressurized high-salinity organic wastewater is introduced into the liquid inlet pipe 104, and the high-salinity organic wastewater enters the liquid and ventilation channel, and is sprayed into the liquid and ventilation channel through a plurality of atomizing nozzles 201 arranged in an array on the curved surface 202. The liquid is instantly atomized in the middle channel of the ring 200, and the atomizing nozzle 201 is shaped like a Venturi nozzle, which can enhance the liquid atomization effect. The atomized wastewater and the high-temperature fluidized air intake are mixed and contacted to quickly pyrolyze and carbonize. The middle channel of the liquid and ventilation ring 200 is narrow in the middle and wide at the upper and lower ends, which has the effect of increasing the air flow velocity and has an obvious chimney effect, which can reduce the power consumption of the air intake fan. During operation, the organic matter in the atomized wastewater is pyrolyzed and carbonized, the water evaporates into water vapor, and the inorganic salt crystallizes and solidifies into salt slag. The mixed gas is discharged from the exhaust pipe 109, and the salt slag and carbide are discharged from the discharge pipe 103d. Since the organic matter is fully pyrolyzed and carbonized, the salt slag discharged from the discharge pipe 103d can be recycled.

[0048] In order to further improve the scope of application, the tower body 103 is also connected to a second air inlet pipe 112, and the second air inlet control valve 111 is connected to the second air inlet pipe 112. When the second air inlet control valve 111 is opened, the outer end of the second air inlet pipe 112 is connected to the liquid inlet and air inlet channels, and when the second air inlet control valve 111 is closed, the outer end of the second air inlet pipe 112 is isolated from the liquid inlet and air inlet channels; the tower body 103 is also connected to a first pressure relief valve 300 connected to the liquid inlet and air inlet channels, a second pressure relief valve 900 is connected to the tower body 103 at the wind chamber 103e, a feed pipe 106 is connected to the tower body 103 above the liquid inlet pipe 104, and a feed control valve 107 is connected to the feed pipe 106. When the feed control valve 107 is opened, the feed pipe 106 is connected to the inner cavity 103c, and when the feed control valve 107 is closed, the feed pipe 106 is isolated from the inner cavity 103c.

[0049] When removing organic matter from waste salt solid waste, the first air inlet control valve 102 is opened, and the external high-temperature air enters the air chamber 103e through the first air inlet pipe 101, and is evenly blown into the inner cavity 103c through the plurality of air holes 801b arranged on the plurality of air caps 801. The temperature is measured by the temperature sensor 400, and the air inlet temperature is controlled between 600°C and 800°C according to the different feed materials. The wind speed is measured by the speed measuring air pipe 108, and the air inlet speed is controlled according to the working conditions. The second air inlet control valve 111 is opened, and the external high-temperature air enters the liquid and air passage through the second air inlet pipe 112, and is sprayed into the middle passage through the atomizing nozzle 201, and the atomizing nozzle 201 is used to spray the atomizing nozzle 201 into the middle passage. The air pressure at the nozzle 201 is controlled to be 10% of the air pressure in the wind chamber 103e. The airflow ejected from the atomizing nozzle 201 is conducive to the fluidization of the waste salt particles and can also effectively prevent the atomizing nozzle 201 from being blocked. The feed control valve 107 is opened, and the waste salt particles are introduced into the feed pipe 106 and input into the tower body 103. Under the action of the high-temperature fluidizing wind in the tower body 103, they are fully fluidized, and the heat of the fluidizing air is fully mixed with the waste salt particles, which improves the efficiency of heat and mass transfer, so that the organic matter in the waste salt is fully oxidized and pyrolyzed, and the fully pyrolyzed and carbonized salt slag falls to the bottom and is discharged from the tower body 103 through the slag discharge pipe 803, the lower head 103a, and then through the discharge pipe 103d.

[0050] During the organic matter removal process, overpressure at any point will trigger the corresponding pressure relief valve to open and release pressure.

[0051] In order to further avoid the deposition of salt slag on the upper air distribution plate 802, a circular purge pipe 500 is connected to the tower body 103 above the upper air distribution plate 802, and the purge pipe 500 has a closed annular air intake space 501. The tower body 103 is connected to a purge air intake pipe 600, and the purge air intake pipe 600 is connected to a purge air intake valve 700. One end of the purge air intake pipe 600 is outside the tower body 103, and the other end of the purge air intake pipe 600 is connected to the purge pipe 500 and connected to the air intake space 501. The inner wall of the purge pipe 500 is provided with a plurality of purge holes 502 connected to the air intake space 501.

[0052] During the organic matter removal process, the purge air inlet valve 700 is intermittently controlled to open several times, and gas is introduced into the purge air inlet pipe 600, and air is blown onto the upper wind plate through the purge hole 502 to prevent residue from being deposited on the upper wind plate, and the residual salt residue is blown into the slag discharge pipe 803. At the same time, it can also promote the salt residue in the lower cone head to be discharged faster along the discharge pipe 103d.

[0053] Example 2

[0054] Reference Figures 1 to 8 This embodiment is based on Example 1, and the difference from Example 1 is that this embodiment of the present invention provides a method for removing organic matter from waste salt using a removal device, which can further achieve the removal of organic matter from high-salt organic wastewater and waste salt solid waste.

[0055] When removing organic matter from high-salt organic wastewater, the following steps are included:

[0056] The first air inlet control valve 102 is opened, and the external high-temperature air enters the air chamber 103e through the first air inlet pipe 101, and the air is blown upward into the inner cavity 103c through the hollow cavity 801a and the air hole 801b in sequence. The temperature sensor 400 detects the temperature inside the tower body 103 above the upper wind plate, and controls the air inlet temperature to be between 500°C and 700°C according to different working conditions. The wind speed is measured by the speed measuring air pipe 108, and the air inlet speed is adjusted and controlled according to the working conditions;

[0057] Open the liquid inlet control valve 105, and the pressurized high-salt organic wastewater from the outside enters the liquid inlet and air inlet channel through the liquid inlet pipe 104, and is sprayed into the liquid and air ring 200 through the atomizing nozzle 201 and instantly atomized, the organic matter is pyrolyzed and carbonized, the water evaporates into water vapor, the inorganic salt crystallizes and solidifies into salt slag, and the mixed gas is discharged from the exhaust pipe 109, and the salt slag and carbide are discharged from the discharge pipe 103d;

[0058] During operation, the purge air inlet valve 700 is controlled to open at a set interval to prevent salt slag from being deposited on the upper side of the upper air distribution plate 802;

[0059] When the operation is completed, the liquid inlet control valve 105 is closed, the high-salt wastewater supply is cut off, the first air inlet control valve 102 is closed, the gap control purge air inlet valve 700 is opened, air is ventilated into the purge pipe 500, and air is blown through the purge hole 502 to blow the residual salt slag into the slag discharge pipe 803, so that the salt slag is discharged from the discharge pipe 103d;

[0060] The process of removing organic matter from waste salt solid waste includes the following steps:

[0061] The first air inlet control valve 102 is opened, and the external high-temperature air enters the air chamber 103e through the first air inlet pipe 101, and is evenly blown to the inner cavity 103c through the air holes 801b. The temperature sensor 400 detects the temperature inside the tower body 103 above the upper wind plate, and controls the air inlet temperature to be between 600°C and 800°C according to different working conditions. The wind speed is measured by the speed measuring air pipe 108, and the air inlet speed is adjusted and controlled according to the working conditions.

[0062] The second air inlet control valve 111 is opened, and the external high-temperature air enters the liquid ventilation channel through the second air inlet pipe 112, and is sprayed into the liquid ventilation ring 200 through the atomizing nozzle 201. By controlling the air pressure entering the second air inlet pipe 112 and the first air inlet pipe 101, the air pressure at the atomizing nozzle 201 is controlled to be 10% of the air pressure of the wind chamber 103e. The airflow sprayed from the atomizing nozzle 201 helps the fluidization of the waste salt particles and effectively prevents the atomizing nozzle 201 from being blocked.

[0063] Open the feed control valve 107, and the external waste salt particles are fed into the tower body 103 through the feed pipe 106. Under the action of the high-temperature fluidizing air in the tower body 103, the salt slag that is fully pyrolyzed and carbonized falls to the bottom and is discharged from the tower body 103 through the slag discharge pipe 803 and the discharge pipe 103d in turn, and the mixed gas is discharged from the exhaust pipe 109;

[0064] During operation, the purge air inlet valve 700 is controlled to open at a set interval to prevent salt slag from being deposited on the upper side of the upper air distribution plate 802;

[0065] When the operation is completed, the feed control valve 107 is closed to cut off the high-salt particle supply, the second air inlet control valve 111 is closed to cut off the high-temperature air supply, the gap control purge air inlet valve 700 is opened, and the gas entering the purge pipe 500 is blown through the purge hole 502 to blow the residual salt slag into the slag discharge pipe 803, so that the salt slag is discharged from the discharge pipe 103d.
