A process for stably controlling the temperature and pressure of heating steam during waste incineration.

Abstract

This invention belongs to the field of waste incineration, specifically a process for stably controlling the temperature and pressure of heating steam during waste incineration. Addressing the problem that some waste may carry moisture before being fed into the incinerator, affecting subsequent incineration efficiency, and that the device struggles to adjust pressure and temperature promptly when changes occur within the incinerator, this invention proposes the following solution, comprising the following steps: S1, feeding the waste into the pre-incineration section inside the incineration device, preparing for incineration; S2, allowing the incinerated flue gas to first pass through the pre-incineration section before being discharged, thus pre-drying the waste. In this invention, the waste is fed into the pre-incineration tube for drying, preventing excessive moisture content. When the internal pressure of the device is unstable, the pressure inside the incinerator is adjusted. When the temperature inside the device changes, the flue gas is returned to the inside of the incinerator to raise the device temperature.

Description

Technical Field

[0001] This invention relates to the field of waste incineration technology, and in particular to a process for stably controlling the temperature and pressure of heating steam during waste incineration. Background Technology

[0002] Waste incineration is a process in which waste is reduced in volume through appropriate thermal decomposition, combustion, and melting reactions at high temperatures, becoming residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment systems to prevent heavy metals, organic pollutants, and other contaminants from being released back into the environment. Recovering the heat generated during waste incineration achieves the goal of waste resource utilization. Waste incineration is an older and traditional method of waste treatment. Because incineration significantly reduces waste volume, saves land, eliminates pathogens, and transforms toxic and harmful substances into harmless ones, it has become one of the main methods of urban waste management. Modern waste incinerators are equipped with effective flue gas purification devices to reduce air pollution.

[0003] Existing waste incineration facilities still have the following drawbacks when in use:

[0004] 1. Before being put into the incinerator, some of the garbage may contain moisture, which may affect the subsequent incineration effect;

[0005] 2. When the pressure and temperature inside the incinerator change, the device has difficulty adjusting the pressure and temperature in a timely manner, making it inconvenient to use.

[0006] To address the aforementioned problems, this invention proposes a process for stably controlling the temperature and pressure of heating steam during waste incineration. Summary of the Invention

[0007] This invention provides a process for stably controlling the temperature and pressure of heating steam during waste incineration. It solves the shortcomings of existing technologies, such as the fact that some waste may carry moisture before being put into the incinerator, which may affect the subsequent incineration effect, and that the device is difficult to adjust the pressure and temperature in a timely manner when the pressure and temperature inside the incinerator change.

[0008] This invention provides the following technical solution:

[0009] A process for stably controlling the temperature and pressure of heating steam during waste incineration includes the following steps:

[0010] S1. The waste is fed into the pre-incineration section inside the incineration unit, ready for incineration;

[0011] S2. The flue gas after incineration can be first introduced into the pre-incineration section and then discharged, which can dry the garbage in advance.

[0012] S3. If the gas pressure is too low during the incineration process, the rate of flue gas discharge can be adjusted to control the gas pressure. If the temperature is too low, the discharged flue gas can be returned to the incineration device.

[0013] In one possible design, the incineration device includes an incinerator, one side of which is fixedly connected to a pre-incineration tube, and one end of the pre-incineration tube is provided with a sealing component for sealing.

[0014] The top of the incinerator is fixedly connected to a first air outlet pipe and a second air outlet pipe, which are symmetrically arranged. The top of the pre-incineration pipe is fixedly connected to a connecting pipe, one end of which is connected to the bottom of the first air outlet pipe. The bottom of the incinerator is fixedly connected to a sewage discharge pipe and an air inlet pipe, and one end of the air inlet pipe is provided with an air inlet component for controlling the air inlet rate.

[0015] The pre-incineration tube is equipped with a drying component for drying the waste.

[0016] In one possible design, the sealing assembly includes a mounting base fixedly connected to one side of the incinerator, a door at the bottom of the mounting base that cooperates with the pre-incineration tube, and a sealing gasket on one side of the door.

[0017] In one possible design, the air intake assembly includes a connecting pipe fixedly connected to the bottom of the air intake pipe, a rectangular box fixedly connected to the bottom of the connecting pipe, a filter pipe fixedly connected to one end of the rectangular box, a first filter plate fixedly connected inside the filter pipe, a second servo motor fixedly connected to one side of the rectangular box, the output shaft of the second servo motor rotating through the rectangular box and fixedly connected to the second filter plate, and multiple filter holes being opened inside both the first filter plate and the second filter plate.

[0018] In one possible design, the drying assembly includes a circular hole on one side of the pre-incineration tube, a discharge port at the bottom of the pre-incineration tube, a first servo motor fixedly connected to the bottom of the incinerator, the output shaft of the first servo motor rotating through the incinerator and fixedly connected to a screw, a first baffle threaded on the outer wall of the screw, the first baffle cooperating with the discharge port, and the first baffle slidably connected to the inner wall of one side of the incinerator.

[0019] In one possible design, the drying assembly further includes a fixing block fixedly connected to the bottom of the pre-incineration tube. A hollow cylinder slides through the interior of the circular hole. A limit plate is fixedly connected to one end of the hollow cylinder. A round rod is fixedly connected to one side of the inner wall of the hollow cylinder. The round rod slides through the fixing block. The fixing block is used in conjunction with a filter tube. A disc is fixedly sleeved on the outer wall of the round rod. The same tension spring is fixedly connected between the fixing block and the disc. The tension spring is sleeved on the round rod. Multiple air holes are opened on the outer wall of the hollow cylinder. A second baffle is fixedly connected to the top of the hollow cylinder. The second baffle is used in conjunction with a connecting tube.

[0020] In one possible design, the bottom of the incinerator is fixedly connected to two symmetrically arranged return pipes, the bottom of which is fixedly connected to a U-shaped pipe. The top of the first and second air outlet pipes is fixedly connected to the same T-shaped pipe. One end of the T-shaped pipe and the two U-shaped pipes is provided with the same four-way valve, and one output port of the four-way valve is fixedly connected to a flue pipe.

[0021] In one possible design, the bottom of the incinerator is fixedly connected to two symmetrically arranged supports, and valves are installed on both the U-shaped pipe and the T-shaped pipe.

[0022] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0023] In this invention, the box door is opened first. At this time, the box door no longer pushes the round rod. The disc moves outward under the tension of the tension spring. The disc drives the round rod to move laterally. The round rod drives the air hole and the limiting plate to move laterally. The limiting plate blocks the round hole. At the same time, the second baffle blocks the connecting pipe. At this time, the inside of the pre-incineration tube is not connected to the incinerator, reducing heat loss. The waste is put into the inside of the pre-incineration tube.

[0024] In this invention, after the box door is closed, the air vent re-enters the interior of the round hole, and the flue gas can enter the interior of the pre-incineration tube through the air vent to dry the waste and prevent it from having excessive moisture. The waste is then discharged through the connecting pipe and enters the interior of the first exhaust pipe, and finally discharged through the exhaust pipe. After drying is completed, the first servo motor can be started. The output shaft of the first servo motor drives the screw to rotate, and the screw drives the first baffle to descend, thereby sending the dried waste into the interior of the incinerator for incineration.

[0025] In this invention, when the internal air pressure of the device is unstable, the exhaust speed of the first exhaust pipe can be controlled by the valve to adjust the pressure inside the incinerator. When the temperature of the device inside the incinerator changes, the flue gas can be returned to the inside of the incinerator by opening the valve on the U-shaped pipe to increase the temperature of the device.

[0026] In this invention, when flue gas enters the device through the filter tube, it will be filtered by the first filter plate and the second filter plate. When it is necessary to control the air intake rate, the second servo motor can be started. The output shaft of the second servo motor drives the second filter plate to rotate. At this time, the overlapping area of ​​the filter holes on the second filter plate and the first filter plate changes, thereby adjusting the air intake rate.

[0027] In this invention, after the box door is opened, the door no longer pushes the round rod, and the interior of the pre-incineration tube is not connected to the incinerator, reducing heat loss. Waste is put into the interior of the pre-incineration tube, and flue gas can enter the interior of the pre-incineration tube through the air hole to dry the waste and avoid excessive moisture in the waste. When the internal air pressure of the device is unstable, the exhaust speed of the first air outlet pipe can be controlled by the valve to adjust the pressure inside the incinerator. When the temperature of the device inside the incinerator changes, the flue gas can be returned to the interior of the incinerator by opening the valve on the U-shaped tube to increase the temperature of the device.

[0051] S3. If the gas pressure is too low during the incineration process, the rate of flue gas discharge can be adjusted to control the gas pressure. If the temperature is too low, the discharged flue gas can be returned to the incineration device.

[0052] The incineration device includes an incinerator. Two symmetrically arranged return pipes are fixedly connected to the bottom of the incinerator. A U-shaped pipe is fixedly connected to the bottom of each return pipe. The tops of the first and second exhaust pipes are fixedly connected to the same T-shaped pipe. A common four-way valve is installed at one end of the T-shaped pipe and the two U-shaped pipes. One output port of the four-way valve is fixedly connected to an exhaust pipe. A pre-combustion pipe is fixedly connected to one side of the incinerator. Two symmetrically arranged supports are fixedly connected to the bottom of the incinerator. Valves are installed on both the U-shaped pipe and the T-shaped pipe. When the internal gas pressure of the device is unstable, the exhaust speed of the first exhaust pipe can be controlled by the valves to adjust the pressure inside the incinerator. The device also adjusts the pressure inside the incinerator when the internal temperature changes. By opening the valve on the U-shaped tube, the flue gas can be returned to the interior of the incinerator to increase the temperature of the device. One end of the pre-incineration tube is equipped with a sealing assembly for sealing. The sealing assembly includes a mounting base fixedly connected to one side of the incinerator. The bottom of the mounting base is equipped with a door. The door works in conjunction with the pre-incineration tube. A sealing gasket is provided on one side of the door. First, the door is opened. At this time, the door no longer pushes the round rod. The disc moves outward under the tension of the tension spring. The disc drives the round rod to move laterally. The round rod drives the air hole and the limiting plate to move laterally. The limiting plate blocks the round hole. At the same time, the second baffle blocks the connecting pipe. At this time, the interior of the pre-incineration tube is not connected to the incinerator, reducing heat loss. Waste is put into the interior of the pre-incineration tube.

[0053] The top of the incinerator is fixedly connected to a first air outlet pipe and a second air outlet pipe, which are symmetrically arranged. The top of the pre-incineration pipe is fixedly connected to a connecting pipe, one end of which is connected to the bottom of the first air outlet pipe. The bottom of the incinerator is fixedly connected to a sewage discharge pipe and an air inlet pipe. One end of the air inlet pipe is equipped with an air inlet assembly for controlling the air inlet rate. The air inlet assembly includes a connecting pipe fixedly connected to the bottom of the air inlet pipe. The bottom of the connecting pipe is fixedly connected to a rectangular box, one end of which is fixedly connected to a filter pipe. The interior of the filter pipe is fixedly connected to... The rectangular box is equipped with a first filter plate and a second servo motor is fixedly connected to one side. The output shaft of the second servo motor rotates through the rectangular box and is fixedly connected to the second filter plate. The first and second filter plates are both provided with multiple filter holes. When the flue gas enters the device through the filter pipe, it will be filtered by the first and second filter plates. When it is necessary to control the air intake rate, the second servo motor can be started. The output shaft of the second servo motor drives the second filter plate to rotate. At this time, the overlapping area of ​​the filter holes on the second and first filter plates changes, thereby adjusting the air intake rate.

[0054] The pre-incineration tube is internally equipped with a drying assembly for drying waste. The drying assembly includes a circular hole on one side of the pre-incineration tube and a discharge port at the bottom of the tube. A first servo motor is fixedly connected to the bottom of the incinerator. The output shaft of the first servo motor rotates through the incinerator and is fixedly connected to a screw. A first baffle is threaded onto the outer wall of the screw, and the first baffle cooperates with the discharge port. The first baffle is slidably connected to the inner wall of one side of the incinerator. The drying assembly also includes a fixing block fixedly connected to the bottom of the pre-incineration tube. A hollow cylinder slides through the circular hole. A limit plate is fixedly connected to one end of the hollow cylinder. A round rod is fixedly connected to the inner wall of one side of the hollow cylinder, and the round rod slides through the fixing block. The fixing block is connected to a filter. The tube is used in conjunction with the circular rod. A circular disc is fixedly sleeved on the outer wall of the circular rod. The same tension spring is fixedly connected between the fixed block and the circular disc. The tension spring is sleeved on the circular rod. Multiple air holes are opened on the outer wall of the hollow cylinder. A second baffle is fixedly connected to the top of the hollow cylinder. The second baffle works in conjunction with the connecting tube. After the box door is closed, the air holes re-enter the interior of the circular holes. The flue gas can enter the interior of the pre-incineration tube through the air holes to dry the garbage and prevent the garbage from having too much moisture. Then it is discharged through the connecting tube and enters the interior of the first exhaust pipe. Finally, it is discharged through the exhaust pipe. After drying is completed, the first servo motor can be started. The output shaft of the first servo motor drives the screw to rotate. The screw drives the first baffle to descend, which can then send the dried garbage into the interior of the incinerator for incineration.

[0055] The working principle and usage process of this technical solution are as follows:

[0056] When in use, first open the box door. At this time, the box door will no longer push the round rod. The disc moves outward under the tension of the tension spring. The disc drives the round rod to move laterally. The round rod drives the air hole and the limiting plate to move laterally. The limiting plate blocks the round hole. At the same time, the second baffle blocks the connecting pipe. At this time, the inside of the pre-incineration tube is not connected to the incinerator, reducing heat loss. The garbage is put into the inside of the pre-incineration tube.

[0057] After the box door is closed, the air vent re-enters the interior of the round hole, and the flue gas can enter the interior of the pre-incineration tube through the air vent to dry the garbage and prevent it from having too much moisture. Then it is discharged through the connecting pipe and enters the interior of the first exhaust pipe, and finally is discharged through the exhaust pipe. After drying is completed, the first servo motor can be started. The output shaft of the first servo motor drives the screw to rotate, and the screw drives the first baffle to descend, which can then send the dried garbage into the interior of the incinerator for incineration.

[0058] When the internal air pressure of the device is unstable, the exhaust speed of the first exhaust pipe can be controlled by the valve to adjust the pressure inside the incinerator. When the internal temperature of the device changes, the flue gas can be returned to the inside of the incinerator by opening the valve on the U-tube to increase the temperature of the device.

[0059] When flue gas enters the device through the filter tube, it will be filtered by the first filter plate and the second filter plate. When it is necessary to control the air intake rate, the second servo motor can be started. The output shaft of the second servo motor drives the second filter plate to rotate. At this time, the overlapping area of ​​the filter holes on the second filter plate and the first filter plate changes, thereby adjusting the air intake rate.

[0060] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.
