Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and more specifically to a waste incineration device. Background Technology

[0002] Waste disposal has become a global challenge. Traditional landfill disposal not only occupies a large amount of valuable land resources, but also easily causes serious pollution to soil and groundwater. Composting is limited by the complex composition of waste and has a relatively narrow scope of application, which cannot meet the needs of massive waste disposal. In contrast, waste-to-energy incineration has gradually become the mainstream development direction in the field of waste disposal due to its significant advantages of waste reduction, harmlessness and resource recovery.

[0003] However, in actual applications of existing waste-to-energy incineration plants, the lack of efficient centralized heating design prevents the waste from heating up quickly in a short time. The heat distribution in the incineration area is scattered, causing some waste to burn slowly. Furthermore, existing equipment cannot adjust the oxygen supply according to the real-time operating conditions of waste incineration. In the early stages of combustion, insufficient oxygen can easily lead to incomplete combustion, producing large amounts of harmful gases such as carbon monoxide. In the middle and later stages of combustion, excessive oxygen input not only wastes energy but also dilutes the temperature of the combustion area, weakening the combustion effect and greatly reducing the incineration rate of waste, thus prolonging the processing time. Summary of the Invention

[0004] This invention provides a waste incineration device, the purpose of which is to rapidly increase the temperature of waste combustion in a short time, adjust the oxygen supply, and accelerate the incineration rate of waste.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0006] A waste incineration device includes an incineration box, an incineration screen plate snapped onto the inner wall of the incineration box, a combustion aid premixing cylinder provided on one outer wall of the incineration box, the combustion aid premixing cylinder being connected to a feeder; an air inlet pipe provided on the other outer wall of the incineration box, the air inlet pipe being connected to a pressure cylinder via a hexagonal bolt connecting pipe, and a blower provided on the outer wall of the incineration box on the side away from the air inlet pipe.

[0007] Furthermore, a feed funnel is provided at the top of the incinerator.

[0008] Furthermore, a screen frame is provided on top of the incineration screen plate.

[0009] Furthermore, a storage box is provided on the side of the combustion aid premixing cylinder away from the incinerator. A vibrating guide plate is provided inside the storage box. A connecting cylinder is provided on the side of the storage box away from the combustion aid premixing cylinder, and the connecting cylinder is connected to the feeder.

[0010] Furthermore, a limiting frame is fixedly installed on the top of the pressure cylinder, and a pressing rod is hinged on the limiting frame. The pressing rod is connected to the piston rod inside the pressure cylinder.

[0011] Furthermore, both sides of the pressure cylinder are fitted with collars, and a stabilizing frame is fixedly installed at the bottom of the collars.

[0012] The present invention has the following beneficial effects:

[0013] The high-pressure gas generated by the pressurizing cylinder is directly injected through the air inlet pipe to the area below the incineration screen plate. It penetrates the screen holes to form a high-speed airflow from bottom to top, solving the problem of insufficient oxygen supply at the bottom of traditional incinerators. The blower continuously replenishes the combustion air, forming a high-low pressure coordinated oxygen supply mode with the high-pressure gas, ensuring that the oxygen concentration in the furnace is always maintained in the optimal combustion range, and increasing the combustion efficiency inside the incinerator.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Please refer to Figure 1-5This embodiment describes in detail a waste incineration device, including an incineration chamber 1. An incineration screen plate 6 is snapped onto the inner wall of the incineration chamber 1. A combustion aid premixing cylinder 2 is installed on one side of the incineration chamber 1, and the combustion aid premixing cylinder 2 is connected to a feeder. An air inlet pipe 3 is installed on the other side of the incineration chamber 1, and the air inlet pipe 3 is connected to a pressure cylinder 4 via a hexagonal bolt connecting pipe 14. A blower 23 is installed on the side of the incineration chamber 1 away from the air inlet pipe 3. The core component of this waste incineration device is an incineration chamber 1 made of high-temperature resistant material, which can be stainless steel lined with refractory bricks or heat-resistant alloy material. Its volume design must meet the waste incineration requirements. The incineration chamber 1 is a cavity structure with an open top and a closed bottom. Continuous grooves or spaced-out locking structures are provided on the inner walls of both sides. The incineration screen plate 6 is securely snapped onto the locking positions on the inner wall of the incineration chamber 1 by protruding structures on its edges. This design facilitates disassembly and maintenance and can withstand high-temperature loads. The incineration screen plate 6 has evenly spaced through holes on its surface. The hole diameter is adapted to the type of waste being processed, ensuring that the ash falls while the waste has sufficient time to burn completely. The core function of the screen holes is to provide a uniform channel for the combustion-supporting gas entering from below, preventing localized oxygen deficiency.

[0022] To add combustion accelerant, a cylindrical combustion accelerant premixing cylinder 2 is fixedly connected to one outer wall of the incinerator 1. The combustion accelerant is added through a feeder (not shown in the figure), which can be a screw conveyor or a star feeder. The combustion accelerant can be potassium chlorate or potassium nitrate, etc. To provide high-pressure combustion gas, an air inlet pipe 3 is installed on the other outer wall of the incinerator 1. The end of the air inlet pipe 3 is sealed to a pressure cylinder 4 via a bolted connection pipe 14. The pressure cylinder 4 can be a piston compressor or a diaphragm compressor. A blower 23 is installed on the side of the incinerator 1 away from the air inlet pipe 3. The blower 23 is driven by a motor 8, and the air outlet of the blower 23 is connected to the upper space of the incinerator 1, continuously blowing air to maintain the oxygen content for combustion and promoting flue gas flow. During operation, the waste in the incinerator 1 is ignited by the ignition device. During the combustion process, the combustion aid is fed into the combustion aid premixing cylinder 2 through the feeder. High-pressure gas is injected through the pressurizing cylinder 4 through the air inlet pipe 3 to the area below the incineration screen plate 6. The blower 23 continuously replenishes the oxygen-supporting air.

[0023] The top of the incinerator 1 is equipped with a feed hopper 7. In order to facilitate the filling of the incinerator 1, a feed inlet is opened at the center of the top of the incinerator 1, and a feed hopper 7 is set at the feed inlet. Its conical structure guides the waste to fall onto the incineration screen plate 6. A movable cover plate can be installed on the top of the feed hopper 7.

[0024] A screen frame 20 is provided on the top of the incineration screen plate 6. In order to prevent the screen holes of the incineration screen plate 6 from becoming clogged during combustion and to optimize the airflow distribution inside the incineration chamber 1, a screen frame 20 is added to the top of the incineration screen plate 6. The screen frame 20 is composed of metal grids or corrugated high-temperature resistant components, which is used to disperse the pressure of the waste combustion process inside the incineration chamber 1, prevent the screen holes of the incineration screen plate 6 from becoming clogged, and optimize the airflow distribution.

[0025] A storage box 11 is located on the side of the premixed fuel agent cylinder 2 away from the incinerator 1. A vibrating guide plate 12 is installed inside the storage box 11. A connecting cylinder 13 is located on the side of the storage box 11 away from the premixed fuel agent cylinder 2, and the connecting cylinder 13 is connected to a feeder. The outer end of the premixed fuel agent cylinder 2 is connected to the storage box 11. The vibrating guide plate 12, which stores the fuel agent, allows the premixed fuel agent cylinder 2 to be tilted. The vibrating guide plate 12 vibrates via a piezoelectric ceramic actuator, continuously vibrating the fuel agent into the incinerator 1. The connecting cylinder 13 on the side of the storage box 11 away from the incinerator 1 is used to connect to the feeder, allowing the fuel agent to be added to the storage box 11 as needed.

[0026] A limiting bracket 17 is fixedly installed on the top of the pressurizing cylinder 4. The limiting bracket 17 is hinged to the pressing rod 18, which is connected to the piston rod inside the pressurizing cylinder 4 (not shown in the figure). The limiting bracket 17 has a U-shaped groove in the middle to engage the pressing rod 18 and limit its movement trajectory. The pressing rod 18 is connected to the piston rod inside the pressurizing cylinder 4. When the pressing rod 18 is lifted, the piston rod inside the pressurizing cylinder 4 drives the piston to draw in air from the outside. When the pressing rod 18 is pressed down, the piston forces the compressed gas into the incinerator 1. A return spring is provided at the end of the movement stroke of the pressing rod 18 to achieve automatic return.

[0027] Both sides of the pressure cylinder 4 are fitted with collars 15, and a stabilizing frame 16 is fixedly installed at the bottom of the collars 15. To increase the overall stability of the pressure cylinder 4, collars 15 are fitted onto the outer walls of both sides of the cylinder body, and the collars 15 are fixed to the cylinder body by metal clamps and fastening bolts. A stabilizing frame 16 is welded to the bottom of each collar 15. The stabilizing frame 16 is composed of channel steel as support legs and equipped with a fixed base plate, which significantly enhances the equipment's anti-overturning ability.

[0028] Device workflow:

[0029] Before operation, check the amount of combustion aid storage box 11 and the sealing of all components. After the waste is fed into the incinerator 1 through the feeding funnel 7, it is ignited by the ignition device. During combustion, combustion aid is continuously added through the combustion aid premixing cylinder 2. The piston rod and piston inside the pressure cylinder 4 are synchronously driven by the pressing rod 18, and the resulting high-pressure gas is injected through the air inlet pipe 3 to the area below the incineration screen plate 6. The high-pressure gas penetrates the screen frame 20 and the screen holes of the incineration screen plate 6, enhancing the combustion intensity at the bottom of the waste layer. The blower 23 continuously supplies oxygen-enhancing air. The flue gas generated during incineration needs to be purified to remove harmful substances and ensure that emissions meet environmental standards. Finally, the ash falls through the screen holes to the bottom of the incinerator 1 and is removed by the ash removal mechanism. The heat released from the incinerator 1 is used to heat water, generating steam to drive the turbine. The turbine is connected to a generator, ultimately converting the steam into electrical energy.
