Description

Technical Field

[0001] This invention relates to the field of waste incineration, and more particularly to a waste incineration system and its usage. Background Technology

[0002] With increasing public awareness of environmental issues, the rational treatment of waste plays an increasingly important role in practicing the concept of green development and promoting ecological civilization. Currently, the primary method for treating municipal solid waste is incineration, aiming to achieve resource recovery, harmless treatment, and volume reduction. Incineration accounts for as much as 72% of waste treatment. Although waste incineration systems have developed, problems such as incomplete incineration and the inability to fully control pollutant emissions in flue gas still exist. Therefore, pollution caused by incomplete incineration and insufficient flue gas purification during waste incineration remains one of the key issues that urgently need to be addressed for efficient, clean, and stable waste incineration.

[0003] As the main component for processing municipal solid waste, the furnace body is a key factor in uneven waste incineration and the generation of harmful gases. A well-designed incineration system can efficiently process municipal solid waste, effectively reduce pollutant emissions, and decrease land use, thus promoting sustainable development. By modifying the internal layout of the furnace, waste can be evenly distributed and fully combusted, improving the incineration rate. The high-temperature flue gas emitted can be reused to achieve energy recycling, accelerate the incineration speed, increase the furnace temperature, and greatly improve the combustion effect. At the same time, harmful gases generated are purified through a well-designed flue gas purification system to meet national emission standards before being discharged. This is also the key to achieving a highly efficient, clean, and stable incineration system. Summary of the Invention

[0029] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] like Figures 1 to 7 As shown, a waste incineration system includes: a feeding mechanism 1, a furnace body mechanism 2, a reciprocating grate mechanism 3, multiple jet mechanisms 4, an energy storage mechanism 5, a flue gas purification mechanism 6, a blower 7, a wind box 8, a fan 9, and a power supply and control mechanism; the reciprocating grate mechanism 3 is inclinedly disposed within the furnace body mechanism 2, the jet mechanisms 4 are disposed within the furnace body mechanism 2 and above the reciprocating grate mechanism 3, the feeding mechanism 1 is disposed on the outer wall of the furnace body mechanism 2 and above the reciprocating grate mechanism 3, the energy storage mechanism 5 is disposed at the top of the furnace body mechanism 2, the flue gas purification mechanism 6 and the fan 9 are both connected to the energy storage mechanism 5, the blower 7 is connected to the wind box 8, the wind box 8 is connected to the reciprocating grate mechanism 3 and the energy storage mechanism 5, and the power supply and control mechanism is connected to the furnace body mechanism 2, the reciprocating grate mechanism 3, the jet mechanisms 4, the flue gas purification mechanism 6, the blower 7 and the fan 9.

[0031] The beneficial effects of this invention are as follows: by setting up an energy storage mechanism, it is beneficial to exchange the heat generated by the combustion of the reciprocating grate mechanism with the external air, fully utilize the waste heat generated by waste incineration, and form bottom air with the wind box and blower, gasification air with the furnace body mechanism, and jet air with the jet mechanism, so that the waste combustion speed is faster and the temperature inside the furnace body mechanism rises more rapidly, optimizing the effect of the reciprocating grate mechanism on waste incineration, thereby achieving complete combustion of waste. At the same time, the flue gas purification mechanism is also beneficial to treat the flue gas generated by waste incineration and avoid environmental pollution.

[0032] Preferred, such as Figure 4 As shown, the furnace body mechanism 2 includes: a first furnace body 201, a second furnace body 202, a furnace chamber 203, a temperature sensor 204, a CO concentration monitor 205, and a gasification component 206; the second furnace body 202 is disposed above the first furnace body 201, the furnace chamber 203 is connected to the inner walls of the first furnace body 201 and the second furnace body 202, the temperature sensor 204, the CO concentration monitor 205, and the gasification component 206 are all disposed on the inner wall of the second furnace body 202, the reciprocating grate mechanism 3 is disposed below the furnace chamber 203 and is connected to the inner wall of the first furnace body 201, a plurality of jet mechanisms 4 are arranged around the side wall of the furnace chamber 203, and the power supply and control mechanism is connected to the temperature sensor 204, the CO concentration monitor 205, and the gasification component 206.

[0033] It should be noted that, in the technical solution of the present invention, since the temperature inside the furnace body mechanism 2 is relatively high, the temperature of the hot air obtained after heat exchange with the external natural wind in the energy storage mechanism 5 can reach about 850°C.

[0034] The advantages of adopting the above-mentioned preferred scheme are: the temperature sensor is conducive to monitoring the temperature inside the furnace, the CO concentration monitor is conducive to monitoring the CO concentration inside the furnace, and the gasification component is conducive to spraying out the hot air obtained after heat exchange by the energy storage mechanism, which combines with the smoke and dust generated when burning garbage on the reciprocating grate mechanism, so as to completely burn the small particulate matter in the smoke and dust that has not been burned completely, and fully realize the incineration of garbage.

[0035] Preferred, such as Figure 1 As shown, the feeding mechanism 1 includes a feeding box 101 and a conveying pipe 102. The feeding box 101 is a funnel-shaped structure that communicates with the conveying pipe 102. The conveying pipe 102 communicates with the side wall of the first furnace body 201 and is located above the reciprocating grate mechanism 3.

[0036] The advantages of adopting the above-mentioned preferred solution are: the feed box facilitates the input of the waste to be incinerated into the conveying pipe, and then into the reciprocating grate mechanism.

[0037] Preferred, such as Figure 4 As shown, the jetting mechanism 4 includes: a flue 401, a ring pump 402, a nozzle 403, a throat pipe 404, a diffuser pipe 405, and an air inlet pipe 406. The flue 401 is a tubular structure with both ends connected to the sidewalls of the furnace 203. The ring pump 402, the nozzle 403, the throat pipe 404, and the diffuser pipe 405 are all disposed within the flue 401. The inlet and outlet ends of the nozzle 403 are connected one-to-one to the ring pump 402 and the throat pipe 406. At one end of 4, the throat tube 404, away from the nozzle 403, is connected to the diffuser tube 405. The air inlet tube 406 is located on the side wall of the flue 401 and is connected to the end of the throat tube 404 near the nozzle 403. The throat tube 404 is a tubular structure with a middle diameter smaller than the diameters at both ends. The reciprocating grate mechanism 3 is located below the connection point between the flue 401 and the side wall of the furnace 203. The power supply and control mechanism is connected to the gas ring pump 402.

[0038] It should be noted that, in the preferred embodiment of the present invention, as... Figure 4 As shown, the two connection points between the flue 401 and the side wall of the furnace 203 are arranged vertically. The upper connection point is the jet inlet of the flue 401, and the lower connection point is the jet outlet of the flue 401. The size of the jet inlet needs to ensure that a large flow of gas can smoothly enter the flue 401 under negative pressure. The size of the jet outlet needs to ensure that the gas can smoothly flow out of the flue 401. The size of the jet outlet can be smaller than the size of the jet inlet to help form the Venturi effect, thereby generating negative pressure. The contraction ratio of the throat tube 404 is between 2:1 and 4:1; the length-to-diameter ratio of the throat tube 404 is between 5:1 and 7:1; the length-to-diameter ratio of the diffuser tube 405 is between 5:1 and 8:1. The distance between the jet outlet and the waste on the reciprocating grate mechanism 3 is within the range of 0.5 meters to 1.0 meter to avoid direct burning to the grate; The arrangement of the flue 401 can be either a right-angled triangle or an isosceles trapezoid with respect to the furnace 203, such as... Figure 4 and Figure 5 As shown, but not limited to, the air ring pump 402, the nozzle 403, the throat pipe 404, and the diffuser pipe 405 can be installed at different positions on the flue 401, such as the hypotenuse of a right triangle or the upper base of an isosceles trapezoid. The installation position can be adjusted according to the actual site conditions. A 45° elbow can be installed at the bend of the right triangle flue 401. The selectivity of the flue 401 arrangement brings convenience to the actual construction situation on site, and will not cause construction difficulties due to the fixed arrangement of the flue 401, thus providing convenience for construction and component installation. The principle of the jet mechanism 4 generating jet air is as follows: the air ring pump 402 pressurizes the gas and introduces the pressurized gas into the nozzle 403 for ejection. When the high-pressure gas passes through the throat pipe 404, the gas velocity increases due to the reduction in cross-sectional area, and the static pressure of the gas (the pressure to overcome the pipe resistance) decreases, thereby generating negative pressure. This causes the high-temperature gas in the furnace 203 to be drawn into the nozzle 403 from the jet inlet, and then ejected from the diffuser pipe 405 onto the surface of the waste above the reciprocating grate mechanism 3. Additionally, the high-temperature gas obtained after heat exchange in the energy storage mechanism 5 is drawn into the throat pipe 404 from the air inlet pipe 406, and then ejected from the diffuser pipe 405 onto the surface of the waste above the reciprocating grate mechanism 3. like Figure 6 As shown, to adjust the positions of the high-pressure jet air inlet and outlet, at least four flue inlets and outlets at different heights are provided on the vertical surface of the furnace 203. The interval between the flue inlets and outlets is based on on-site measurement data. Assuming they are numbered from top to bottom as first inlet, second inlet, first outlet, and second outlet, adjustments are made based on the temperature detected by the temperature sensor 204 within the furnace body mechanism 2 and the combustion status of the waste. For example, if the contact area between the flame front generated by the high-temperature gas ejected from the diffuser 405 and the reciprocating grate mechanism 3 is large, the first outlet can be adjusted. By closing the second outlet and opening the first outlet, or by closing the first inlet and opening the second inlet, the combustion conditions in the furnace 203 can be adjusted. This allows for adjustment of the inlet and outlet heights based on the temperature within the furnace structure, and also adjusts the air guide area of ​​the pipe. This method can be used to regulate flue gas discharge, and the operation is simple and easy. For incinerators operating under negative pressure, the first furnace body 201 and the second furnace body 202 can prevent cold air from leaking into the furnace 203 or the flue 401, so as to avoid a decrease in the combustion efficiency of the incinerator and affect its economic efficiency. During the process of adding the jet mechanism 4 to the existing incinerator, at least one flue inlet and outlet at different heights needs to be opened on the vertical surface of the furnace 203. The diameter of the opening is selected according to the flue gas flow rate of the jet mechanism 4. A prefabricated flue with high temperature resistance and good heat insulation performance is arranged at the opening position. After the flue 401 is arranged, the contact surface between the flue 401 and the furnace 203 is sealed. The inlet end of the flue 401 (i.e., the jet inlet) and the contact section between the flue 401 and the first furnace body 201 and the second furnace body 202 are sealed with refractory materials (such as clay and silica bricks). The flue 401 is connected and fixed to the surface of the first furnace body 201 and the second furnace body 202 with bolts, and the connection needs to be treated with sealing rings.

[0039] The advantages of adopting the above-mentioned preferred scheme are: it is beneficial to utilize the Venturi effect to form a jet of high-temperature gas in the furnace and the high-temperature gas obtained after heat exchange, and spray it onto the surface of the waste to be incinerated, so as to make secondary use of the high temperature generated by the incineration of waste, improve the energy utilization rate, and make the waste incineration more complete.

[0041] The advantages of adopting the above-mentioned preferred scheme are: it facilitates the heat exchange between the incineration of waste in the furnace body and the external natural wind within the shell, forming high-temperature gas, which is then input into the gasification component to form gasification air, into the air inlet pipe to form jet air, and into the air box to form bottom air, thereby improving energy utilization and comprehensively enhancing the efficiency of waste incineration.

[0043] It should be noted that, in a preferred embodiment of the present invention, the connecting rod for connecting two adjacent movable grates 308 is a steel frame, thereby forming a whole with the multiple movable grates 308. "The uppermost movable grate 308" refers to... Figure 3 In the view shown, the uppermost movable grate 308 is one of the multiple movable grates 308 that are arranged at an angle.

[0044] The advantages of adopting the above-mentioned preferred scheme are as follows: the inclined setting of the main air duct is conducive to the forward movement of garbage from top to bottom, improving combustion efficiency; the movable grate is movably set on the fixed grate, which is conducive to the reciprocating motion on the fixed grate driven by the power cylinder and push-pull rod, so that the garbage can be burned evenly in the furnace to achieve the purpose of drying, burning, drying and burning out; the air outlet of the main air duct and the air outlet of the branch air duct are conducive to outputting the high temperature bottom air to the bottom garbage, drying and burning the bottom garbage, and burning the garbage from all directions.

[0045] Preferred, such as Figure 1As shown, the flue gas purification mechanism 6 includes: a centrifugal dust collector 601, a flue gas cooling pipe 602, a cooler 603, a desulfurization tower 604, a cooling water supply component 605, a neutralization liquid supply component 606, a drying chamber 607, a bag filter 608, an activated carbon adsorber 609, an induced draft fan 610, and a chimney 611. The centrifugal dust collector 601, the flue gas cooling pipe 602, the cooler 603, the desulfurization tower 604, the drying chamber 607, the activated carbon adsorber 609, the bag filter 608, the induced draft fan 610, and the chimney 611 are connected sequentially by pipes. The centrifugal dust collector 601 is connected to the housing 507 by a pipe. The cooling water supply component 605 is connected to the flue gas cooling pipe 602 by a pipe. The neutralization liquid supply component 606 is connected to the desulfurization tower 604 by a pipe.

[0046] The advantages of adopting the above-mentioned preferred scheme are as follows: the centrifugal dust collector is conducive to the preliminary dust removal treatment of the flue gas generated by incineration of waste, and neutralizes it with cooling water in the flue gas cooling pipe to initially reduce the temperature of the flue gas. After that, the flue gas is further cooled in the condenser. The desulfurization tower is conducive to the acid-base neutralization of the flue gas with neutralizing liquid. After the resulting neutral flue gas is dried in the drying box, the smoke in the flue gas is removed by activated carbon adsorber and bag filter, resulting in clean gas with emission standards. Finally, it is discharged into the atmosphere from the chimney under the action of the induced draft fan.

[0047] Preferred, such as Figure 1 As shown, the cooling water supply assembly 605 includes a cooling pump 6051, a water tank 6052, and a cooler 6053. The two ends of the cooler 6053 are connected to the water tank 6052 and the cooling pump 6051 respectively. The end of the cooling pump 6051 away from the cooler 6053 is connected to the flue gas cooling pipe 602 through a pipe.

[0048] The advantages of adopting the above preferred solution are: the cooler is conducive to cooling the water in the water tank, and under the action of the cooling pump, the cooled water is pumped into the flue gas cooling pipe to perform preliminary cooling of the high-temperature flue gas.

[0049] Preferred, such as Figure 1 As shown, the neutralization liquid supply assembly 606 includes a spray pump 6061 and a filter 6062. The two ends of the spray pump 6061 are connected to the filter 6062 and the external neutralization solution respectively. The end of the filter 6062 away from the spray pump 6061 is connected to the desulfurization tower 604 through a spray water pipe.

[0050] It should be noted that, in the technical solution of this invention, the smoke and dust produced by incinerating waste generally contain gases that can easily generate acidity, so sodium hydroxide is selected as the external neutralization solution.

[0051] The advantages of adopting the above-mentioned preferred scheme are: it facilitates the injection of the external neutralizing solution into the desulfurization tower after filtration under the action of the spray pump, and the neutralizing solution is sprayed from top to bottom in the desulfurization tower to fully reduce the acidity of the flue dust and neutralize the acidity and alkalinity of the flue dust.

[0052] like Figure 8 As shown, a method of using a waste incineration system includes the following steps: S1: Preheat furnace body mechanism 2; S2: The waste to be incinerated is fed into the reciprocating grate mechanism 3 through the feeding mechanism 1; S3: Start the fan 9 to inject external natural air into the energy storage mechanism 5, so that the external natural air can exchange heat with the hot air in the furnace body mechanism 2; S4: Inject the hot air after heat exchange in step S3 into the air box 8, the jet mechanism 4 and the furnace body mechanism 2; S5: Start the blower 7 to neutralize the hot air injected into the air box 8 in step S4 with the external natural air injected by the blower 7 to form the furnace bottom air, and inject it into the reciprocating grate mechanism 3; S6: The reciprocating grate mechanism 3 uses the bottom air generated in step S5, the jet air generated in step S4 by the jet mechanism 4, and the gasification air generated by the furnace body mechanism 2 to burn the waste to be incinerated cleanly. S7: Inject the exhaust gas generated by the reciprocating grate mechanism 3 from the incineration of waste into the flue gas purification mechanism 6, and discharge the exhaust gas after treatment.

[0053] It should be noted that in step S1, the furnace body mechanism 2 is preheated by placing a propellant inside the furnace body mechanism 2, so that the temperature inside the furnace body mechanism 2 reaches about 850°C. In step S6, based on the operating conditions of the furnace body mechanism 2 (temperature and CO concentration inside the furnace body mechanism 2), it is determined whether the jet air and furnace bottom air need to be adjusted. If the jet air and furnace bottom air need to be adjusted, the temperature sensor 204 is used to check whether the temperature inside the furnace body mechanism 2 is between 850 and 1100°C. If the temperature inside the furnace body mechanism 2 is between 850 and 1100°C, the operation is stopped.

[0054] If the temperature inside the furnace body mechanism 2 is not between 850 and 1100℃, check if the temperature inside the furnace body mechanism 2 is greater than 1100℃. If the temperature inside the furnace body mechanism 2 is greater than 1100℃, increase the airflow of the blower 7 to lower the temperature in the air box 8. If, after adjusting the airflow of the blower 7, the temperature inside the furnace body mechanism 2 is less than or equal to 1100℃, stop the operation. If the temperature inside the furnace body mechanism 2 is still greater than 1100℃, open the first outlet of the jet air and close the second outlet. If, after reducing the contact area between the flame of the jet air and the combusted material, the temperature inside the furnace body mechanism 2 is less than or equal to 1100℃, stop the operation. If the temperature inside the furnace body mechanism 2 is less than or equal to 1100℃, check if the temperature inside the furnace body mechanism 2 is less than 850℃. If the temperature inside the furnace body mechanism 2 is greater than or equal to 850℃, stop the operation. If the temperature inside the furnace body mechanism 2 is less than 850℃, reduce the air volume of the blower 7 to increase the temperature in the air box 8, and continue to check if the temperature inside the furnace body mechanism 2 is less than 850℃. If the temperature inside the furnace body mechanism 2 is greater than 850℃, stop the operation. If the temperature inside the furnace body mechanism 2 is still less than 850℃, close the first outlet of the jet air and open the second outlet. If, after increasing the contact area between the flame and the combusted material of the jet air, the temperature inside the furnace body mechanism 2 is greater than or equal to 850℃, stop the operation.

[0055] If the jet air and furnace bottom air do not need adjustment, check if the feeding speed of the conveying pipe 102 has increased. If the feeding speed of the conveying pipe 102 has increased, check if the temperature inside the furnace body mechanism 2 is between 850 and 1100°C. If the temperature inside the furnace body mechanism 2 is between 850 and 1100°C, stop the operation. If the temperature inside the furnace body mechanism 2 is not within the range of 850 to 1100°C, check if the temperature inside the furnace body mechanism 2 is greater than 1100°C. If it is greater than 1100°C, slow down the speed of the power cylinder 310 and check again if the temperature inside the furnace body mechanism 2 is greater than 1100°C. If it is not greater than 1100°C, stop the operation. If the temperature inside the furnace body mechanism 2 is less than or equal to 1100℃, check if the temperature inside the furnace body mechanism 2 is less than 850℃. If it is greater than 850℃, stop the operation. If the temperature inside the furnace body mechanism 2 is less than 850℃, increase the speed of the power cylinder 310 and check again if the temperature inside the furnace body mechanism 2 is greater than or equal to 850℃. If it is greater than 850℃, stop the operation. If the temperature inside the furnace body mechanism 2 is still less than 850℃, add combustion aid and check again if the temperature inside the furnace body mechanism 2 is greater than 850℃. If it is greater than 850℃, stop the operation.

[0056] If the feeding speed of the conveying pipe 102 does not increase, check if the temperature inside the furnace body mechanism 2 is between 850 and 1100°C. If the temperature inside the furnace body mechanism 2 is between 850 and 1100°C, stop the operation. If the temperature inside the furnace body mechanism 2 is not between 850 and 1100°C, check if the temperature inside the furnace body mechanism 2 is greater than 1100°C. If it is greater than 1100°C, slow down the speed of the power cylinder 310 and check again if the temperature inside the furnace body mechanism 2 is greater than 1100°C. If it is not greater than 1100°C, stop the operation. If the temperature inside the furnace body mechanism 2 is less than or equal to 1100℃, check if the temperature inside the furnace body mechanism 2 is less than 850℃. If it is greater than 850℃, stop the operation. If the temperature inside the furnace body mechanism 2 is less than 850℃, increase the speed of the power cylinder 310 and check again if the temperature inside the furnace body mechanism 2 is greater than or equal to 850℃. If it is greater than 850℃, stop the operation. If the temperature inside the furnace body mechanism 2 is still less than 850℃, add combustion aid and check again if the temperature inside the furnace body mechanism 2 is greater than 850℃. If it is greater than 850℃, stop the operation.
