[0002] When using a regenerative incinerator to incinerate waste liquid containing alkynyl hydrocarbon components, the waste liquid decomposes into incineration tail gas mainly composed of carbon dioxide and water in the incinerator, and the incineration tail gas needs to be discharged or further reduced according to its components. In the prior art, an RTO regenerative chamber incinerator capable of recovering and storing waste heat and its use method disclosed in the application number: 202311460446.8 specifically disclose a waste heat recovery mechanism for the RTO regenerative chamber incinerator, and the waste heat recovery mechanism is used to recover waste heat during discharge. Since carbon dioxide and water mainly exist in the incineration tail gas, when the temperature drops, the water will condense into droplets. The water gradually condenses into a large amount of liquid water in the waste heat recovery mechanism, and the liquid water is extremely likely to gradually block the coil pipes in the waste heat recovery component, that is, when the water condenses, some inorganic salts are precipitated, and the inorganic salts gradually thicken the pipe wall of the coil pipes, affecting the discharge efficiency of the incineration tail gas. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that the waste heat recovery mechanism of the regenerative incinerator is easily blocked by inorganic salts.

The discharge pipe is also connected to the heat recovery device. The heat recovery device includes a recovery tank connected to the discharge pipe, a coil pipe installed in the recovery tank, a movable bottom plate movably installed at the bottom of the recovery tank, and an adjusting member installed between the side wall of the recovery tank and the movable bottom plate. The recovery tank is connected to the inside of the furnace body through the discharge pipe. The adjusting member includes an insertion pipe fixedly installed at the bottom of the recovery tank, a rotating rod rotatably penetrating through the insertion pipe, and an adjusting rope wound around the rotating rod. The two ends of the adjusting rope are respectively fixedly connected to the rotating rod and the movable bottom plate.

[0005] Further, a sleeve cover is installed at the end of the rotating rod extending out of the recovery tank, and the sleeve cover is fixedly sleeved at the port of the insertion pipe.

[0006] Further, a positioning pin is inserted through the sleeve cover. The end of the positioning pin penetrates through the sleeve cover and the insertion pipe and then penetrates into the rotating rod.

[0007] Further, a ring groove is formed on the part of the rotating rod inside the recovery tank, and the adjusting rope can be received in the ring groove.

[0008] Further, a fixing ring is sleeved on the end of the rotating rod, and the fixing ring is located at the end of the ring groove.

[0009] Further, a positioning cylinder is installed at the central position of the coiled pipe. The top end of the positioning cylinder is fixed on the top of the recovery tank, and a connecting side wall protrudes outward from the positioning cylinder and is fixed on the tank wall of the recovery tank.

[0010] The beneficial effect of the present utility model is that in the heat recovery device of the incinerator, a rotating rod and an adjusting rope are added. The rotating rod extends to the outside of the recovery tank, and the adjusting rope is wound and stored on the rotating rod.

Detailed implementation mode

[0020] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and connotation of the appended claims.

[0021] As Figure 1 shown, this embodiment provides a regenerative incinerator, which includes a furnace body 10, an incineration chamber 20 installed on the furnace body 10, a pipeline device 30 connecting the furnace body 10 and the incineration chamber 20, and a heat recovery device 40 arranged at the tail of the pipeline device 30.

[0022] The furnace body 10 is arranged below the incineration chamber 20. A regenerator is added in the incineration chamber 20 to maintain the temperature level in the incineration chamber 20 by using the regenerator. The furnace body 10 is arranged corresponding to the regenerator, and the furnace body 10 heats the regenerator in the incineration chamber 20. The waste liquid to be treated is discharged into the incineration chamber 20, and the waste liquid is oxidized and decomposed in the incineration chamber 20 to form incineration tail gas containing components such as water, carbon dioxide and inorganic salts. The incineration tail gas is discharged into the heat recovery device 40 through the pipeline device 30, and then enters the next process after recovering heat.

[0023] The pipeline device 30 includes a heat pipe 310 connecting each furnace body 10, a feed pipe 320 connecting each incineration chamber 20, and a discharge pipe 330.

[0024] The end of the heat pipe 310 is connected to a heat source. The heat pipe 310 injects high-temperature gas of the heat source into the furnace body 10. The high-temperature gas enters the incineration chamber 20 from the furnace body 10 to heat the regenerator in the incineration chamber 20 and maintain the incineration chamber 20 within the temperature range where the waste liquid can be oxidized and decomposed. The waste liquid raw material is injected into the incineration chamber 20 through the feed pipe 320, and the raw material is thermally decomposed at high temperature in the incineration chamber 20. One end of the discharge pipe 330 is connected to the incineration chamber 20, and the other end is connected to the heat recovery device 40. The incineration tail gas generated by decomposition in the incineration chamber 20 is transported to the heat recovery device 40 through the discharge pipe 330.

[0025] As shown Figures 1 to 7 in FIG. Figures 1 to 7 , the heat recovery device 40 includes a recovery tank 410 communicating with the discharge pipe 330, a coil pipe 420 installed in the recovery tank 410, a movable floor 430 movably installed at the bottom of the recovery tank 410, and an adjusting member 440 installed between the side wall of the recovery tank 410 and the movable floor 430.

[0026] The recovery tank 410 communicates with the incineration chamber 20 through the discharge pipe 330. The incineration exhaust gas in the incineration chamber 20 enters the recovery tank 410 through the discharge pipe 330. Both ends of the coil pipe 420 extend out of the incineration chamber 20 and then communicate with a heat source. A heat exchange medium circulates in the coil pipe 420, and the heat in the recovery tank 410 is transferred to the heat source by using the heat exchange medium. When the incineration exhaust gas cooled in the recovery tank 410 is cooled, the moisture in the incineration exhaust gas condenses. Finally, the moisture gathers on the movable bottom plate 430. The movable bottom plate 430 can be adjusted by using the adjusting member 440 to change the sealing state of the movable bottom plate 430 with respect to the recovery tank 410. After the movable bottom plate 430 tilts over, the moisture slides off the movable bottom plate 430, realizing the timed discharge of the moisture in the recovery tank 410.

[0027] Preferably, as Figure 2 shown in FIG. Figure 2 , a positioning cylinder 421 is installed at the central position of the coil pipe 420. The top end of the positioning cylinder 421 is fixed on the top of the recovery tank 410, and a connecting side wall 422 protrudes outward from the bottom of the positioning cylinder 421 and is fixed on the wall of the recovery tank 410.

[0028] As Figures 2 to 4 shown in FIG. Figures 2 to 4 , the movable bottom plate 430 is a circular plate formed by butt-jointing two semi-circular arc plates. The two arc plates are connected in a hinged form. One of the arc plates is fixedly installed on the wall at the bottom of the recovery tank 410, and the other arc plate is connected to the adjusting member 440. When one arc plate rotates relative to the other arc plate, a gap is left between the movable bottom plate 430 and the tank wall for the condensed moisture to flow out.

[0029] As Figures 4 to 7 shown in FIG. Figures 4 to 7 , the adjusting member 440 includes an insertion pipe 441 fixed on the bottom of the recovery tank 410, a rotating rod 442 rotatably penetrating through the insertion pipe 441, and an adjusting rope 443 wound around the rotating rod 442.

[0030] The inserted pipe 441 penetrates through the bottom of the recovery tank 410. The rotating rod 442 passes through the inserted pipe 441 from outside the recovery tank 410 into the tank. A sleeve cover 444 is fixedly installed on the end of the rotating rod 442 outside the tank. The sleeve cover 444 can cover the port of the inserted pipe 441. A positioning pin 445 is inserted through the sleeve cover 444. The end of the positioning pin 445 passes through the sleeve cover 444 and the inserted pipe 441 and then penetrates into the rotating rod 442. The angle of the rotating rod 442 relative to the inserted pipe 441 can be fixed by using the positioning pin 445. The adjusting rope 443 is arranged and wound around the rotating rod 442. One end of the adjusting rope 443 is fixed to the rotating rod 442. When the rotating rod 442 is rotated by using the sleeve cover 444, the adjusting rope 443 wound around the rotating rod 442 can be synchronously wound or synchronously loosened. The other end of the adjusting rope 443 is fixed to the movable bottom plate 430. Under the traction of the adjusting rope 443, the blocking situation of the movable bottom plate 430 to the recovery tank 410 can be adjusted. An annular groove 447 for accommodating the adjusting rope 443 is formed on the part of the rotating rod 442 inside the recovery tank 410. The adjusting rope 443 can be wound into the annular groove 447. A fixing ring 446 is sleeved on the end of the rotating rod 442. The fixing ring 446 is located at the end of the annular groove 447. The fixing ring 446 blocks the adjusting rope 443 to prevent the adjusting rope 443 from detaching from the rotating rod 442.

[0031] During the above use, high-temperature gas is injected into the furnace body 10 through the heat pipe 310 in the pipeline device 30. The high-temperature gas heats the heat storage body. The heat storage body maintains the temperature in the incineration chamber 20 at a level capable of incinerating and treating the waste liquid by virtue of its heat preservation performance. The waste liquid is sent into the incineration chamber 20 through the feed pipe 320. The waste liquid is decomposed into incineration tail gas mainly composed of carbon dioxide and water in the incineration chamber. The incineration tail gas enters the recovery tank 410 through the discharge pipe 330. The heat exchange medium in the coil pipe 420 flows back and forth. The heat exchange medium recovers the heat in the incineration tail gas to the heat source. After the temperature of the incineration tail gas drops, part of the inorganic salts and moisture condense into liquid. The liquid accumulates on the movable bottom plate 430. When the liquid on the movable bottom plate 430 reaches a certain height, the positioning pin 445 on the rotating rod 442 is pulled out outside the recovery tank 410, and the rotating rod 442 is rotated by operating the sleeve cover 444. When the rotating rod 442 rotates, the adjusting rope 443 is loosened. The movable arc plate rotates relative to the fixed arc plate, and a gap appears between the movable bottom plate 430 and the tank wall to provide for the water to flow out. When the amount of water discharged is sufficient, the rotating rod 442 is rotated in the reverse direction again until the adjusting rope 443 is wound around the rotating rod 442 again. The movable bottom plate 430 blocks the gap between it and the recovery tank 410 again under the traction of the adjusting rope 443 to prevent heat from leaking through this gap.

[0032] Based on the above-mentioned ideal embodiments of the present utility model as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
