Description

Technical Field

[0001] The present invention relates to the technical field of incineration flue gas treatment, and in particular to an incineration flue gas treatment device and system for solid waste treatment. Background Art

[0002] Incineration flue gas refers to the mixed gas containing various pollutants that is discharged from the boiler outlet along with the hot air flow after the garbage undergoes high-temperature combustion, pyrolysis and oxidation processes during the incineration process.

[0003] In the prior art, solid waste treatment is an important part of the energy-saving and environmental protection industry to achieve the purpose of environmental protection and resource utilization. In the construction of environmental protection projects, incineration is a common means. Flue gas deacidification equipment is often used to purify the flue gas generated by solid waste incineration, such as a wet spray tower. The alkaline absorbent solution absorbs acid gases such as hydrogen chloride and sulfur oxide in the tower. The alkaline absorbent solution reacts with the acid gas in a liquid state. The wet spray tower is generally set downstream of the dust collector, and the deacidification efficiency is high.

[0004] However, it is known from experiments that the optimal deacidification temperature of flue gas is between 140°C and 200°C, and neutralizing the flue gas by wet spraying can easily cause the temperature of the flue gas to drop below the optimal temperature, so wet spray towers are often used in conjunction with flue gas reheating devices, which increases costs.

[0011] Preferably, the inner wall surface of the installation groove close to the discharge pipe side is provided with a positioning groove, the inner wall side surface of the positioning groove is provided with an annular groove, and the sleeve is also provided with an annular groove on the side surface close to the discharge pipe.

[0012] Preferably, the transmission bevel gear is movably provided with an inner wall of a positioning groove, an annular block is fixed to the side surface of the transmission bevel gear, the annular block corresponds to the annular groove and is movably clamped, and the lower inner groove is connected to the positioning groove.

[0014] Preferably, a slide rail is fixed to the inner wall of the sleeve located between the baffle and the transmission bevel gear, a limiting sleeve is fixed at the axis of the movable bracket, a threaded hole is provided on the inner wall of the limiting sleeve fixed to the axis of the movable bracket, a slide groove is provided at the upper end of the movable bracket, and the slide rail corresponds to the slide groove and is movably clamped.

[0015] A system according to the above-mentioned incineration flue gas treatment device for solid waste treatment comprises the following steps: Step 1: Adjustment. High-temperature flue gas is transported to the interior of the reaction tower body through the air inlet pipe. At the same time, alkaline absorbent solution is transported to the adjustment bin through the feed pipe. The alkaline absorbent solution flows through the adjustment bin and enters the discharge pipe. The alkaline absorbent solution in the discharge pipe is pressurized by the pressure pump and sprayed into the interior of the reaction tower body through the nozzle in the form of spray, thereby deacidifying and neutralizing the flue gas inside the reaction tower body. The flue gas is deacidified in the form of spray rather than spraying, so that the flue gas will not contact too much solution at one time, thereby causing a sudden drop in temperature. The deacidified and neutralized flue gas is discharged through the air outlet pipe at the upper end of the reaction tower body. When the temperature sensor inside the air outlet pipe detects that the temperature of the flue gas after deacidification and neutralization is lower than the optimal deacidification temperature, the handle is turned to drive the active bevel gear to rotate through the second guide rod. The rotation of the active bevel gear will drive the transmission bevel gear to rotate. Due to the threaded fit and the movable bracket being restricted by the slide rail and the slide groove, it cannot rotate. Therefore, the rotation of the transmission bevel gear will drive the movable bracket to move along the axis of the screw rod toward the baffle. Since the thickness of the fourth block is greater than that of the third block, the thickness of the third block is greater than that of the second block, and the thickness of the second block is greater than that of the first block, when the movable bracket moves, the fourth block, the threaded hole, the second block and the first block will be stuck and blocked with the multiple groups of feed slots one by one, thereby reducing the flow rate of the alkaline absorbent solution from the regulating bin to the discharge pipe, and reducing the amount of spray sprayed from the nozzle. When the flue gas temperature detected by the temperature sensor is at the optimal temperature, stop turning the handle to maintain the flow rate of the alkaline absorbent solution from the regulating bin to the discharge pipe at this time, and reflect the temperature of the flue gas in the exhaust pipe through the temperature sensor, and then adjust the flow rate of the alkaline absorbent solution in the regulating bin, so as to avoid the nozzle from spraying too much alkaline absorbent solution and prevent the flue gas from cooling too much, thereby ensuring that the flue gas is at the optimal deacidification temperature, without the need for additional heating devices, and reducing costs; Step 2: Stirring. Since the first gear corresponds to and is locked with the second gear, when the handle is turned to adjust the alkaline absorbent solution and thus the flow rate of the bin to the discharge pipe, the rotating second guide rod will drive the first guide rod to rotate through the locking of the first gear and the second gear. The rotation of the first guide rod will drive the stirring blade to rotate. The rotating stirring blade will stir the alkaline absorbent solution stored in the storage tank to prevent the alkaline absorbent solution from precipitating due to a long period of low flow rate, thereby affecting the deacidification and neutralization effect of the flue gas and ensuring the solubility of the alkaline absorbent solution.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The alkaline absorbent solution in the discharge pipe is pressurized by the pressure pump and sprayed into the reaction tower body through the nozzle in the form of spray, thereby deacidifying and neutralizing the flue gas inside the reaction tower body. The flue gas is deacidified in the form of spray rather than spraying, so that the flue gas will not contact too much solution at one time, thereby causing a sudden drop in temperature. The deacidified and neutralized flue gas is discharged through the outlet pipe at the upper end of the reaction tower body. When the temperature sensor inside the outlet pipe detects that the temperature of the flue gas after deacidification and neutralization is lower than the optimal deacidification temperature, the handle is turned to drive the active bevel gear to rotate through the second guide rod, and the rotation of the active bevel gear will drive the transmission bevel gear to rotate, and the rotation of the transmission bevel gear will drive the movable bracket to approach the baffle along the axis of the screw. When the movable bracket moves, the fourth block, the threaded hole, the second block and the first block will be stuck and blocked with the multiple groups of feed troughs one by one, thereby reducing the flow rate of the alkaline absorbent solution from the regulating bin to the discharge pipe, and reducing the spray volume sprayed from the nozzle. When the flue gas temperature detected by the temperature sensor is at the optimal temperature, stop turning the handle to maintain the flow rate of the alkaline absorbent solution from the regulating bin to the discharge pipe at this time. This component reacts the temperature of the flue gas in the exhaust pipe through the temperature sensor, and then adjusts the flow rate of the alkaline absorbent solution in the regulating bin, thereby avoiding the nozzle from spraying too much alkaline absorbent solution and preventing the flue gas from cooling too much, thereby ensuring that the flue gas is at the optimal deacidification temperature. No additional heating device is required, which reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention also discloses a system of a solid waste incineration flue gas treatment device, comprising the following steps: Step 1: Adjustment, high-temperature flue gas is transported to the interior of the reaction tower body 1 through the air inlet pipe 3, and at the same time, an alkaline absorbent solution is transported to the adjustment bin 2 through the feed pipe 6. The alkaline absorbent solution flows through the adjustment bin 2 and enters the discharge pipe 8. The alkaline absorbent solution in the discharge pipe 8 is pressurized by the pressure pump 9 and sprayed into the interior of the reaction tower body 1 through the nozzle 10 in the form of a spray, thereby deacidifying and neutralizing the flue gas in the reaction tower body 1. The flue gas is deacidified in the form of a spray instead of a spray, so that the flue gas is not The deacidification and neutralization flue gas will be exposed to too much solution at one time, resulting in a sudden drop in temperature. The deacidification and neutralization flue gas is discharged through the outlet pipe 4 at the upper end of the reaction tower body 1. When the temperature sensor 5 inside the outlet pipe 4 detects that the temperature of the flue gas after deacidification and neutralization is lower than the optimal deacidification temperature, the handle 7 is turned to drive the active bevel gear 22 to rotate through the second guide rod 21. The rotation of the active bevel gear 22 will drive the transmission bevel gear 23 to rotate. Due to the threaded fit and the movable bracket 28 being restricted by the slide rail 32 and the slide groove 34 and unable to rotate, the transmission bevel gear 23 is The rotation of the screw 23 will drive the movable bracket 28 to move along the axis direction of the screw 29 close to the baffle 30.

Since the first gear 19 corresponds to and is locked with the second gear 20, when the handle 7 is turned to adjust the alkaline absorbent solution and thus adjust the flow rate of the bin 2 to the discharge pipe 8, the rotating second guide rod 21 will drive the first guide rod 18 to rotate through the locking of the first gear 19 and the second gear 20.

The temperature of the smoke in the discharge pipe (4) is reflected by the temperature sensor (5), and the flow rate of the alkaline absorbent solution in the regulating chamber (2) is adjusted to avoid the nozzle (10) spraying too much alkaline absorbent solution, thereby preventing the smoke from cooling too much, thereby ensuring that the smoke is at an optimal deacidification temperature, without the need for an additional heating device, and reducing costs; Step 2: stirring. Since the first gear (19) and the second gear (20) correspond to each other and are locked, when the handle (7) is turned to adjust the flow rate of the alkaline absorbent solution and thus adjust the flow rate of the alkaline absorbent solution from the bin (2) to the discharge pipe (8), the rotating second guide rod (21) will drive the first guide rod (18) to rotate through the locking of the first gear (19) and the second gear (20). The rotation of the first guide rod (18) will drive the stirring blade (11) to rotate. The rotating stirring blade (11) will stir the alkaline absorbent solution stored in the storage tank (12) in transit, thereby preventing the alkaline absorbent solution from precipitating due to a long period of low flow rate, thereby affecting the deacidification and neutralization effect of the flue gas, and ensuring the solubility of the alkaline absorbent solution.
