Description

Technical Field

[0001] This utility model belongs to the technical field of pyrolysis gasification furnaces, specifically relating to a sludge pyrolysis gasification furnace. Background Technology

[0002] A pyrolysis gasification furnace is a device used to convert organic waste (such as sludge, biomass, and garbage) into combustible gases, liquids, and solids through pyrolysis and gasification processes. Pyrolysis refers to heating organic waste to a certain temperature (usually 300-800℃) under anaerobic or oxygen-deficient conditions, causing the organic matter to undergo a cracking reaction, producing pyrolysis gas, pyrolysis oil, and semi-coke. During this process, high-molecular-weight compounds in the organic matter are decomposed into low-molecular-weight compounds. Gasification refers to the gasification reaction of the semi-coke and some of the pyrolysis gas produced by pyrolysis under the action of a gasifying agent (such as oxygen, water vapor, or carbon dioxide), generating syngas, mainly composed of carbon monoxide, hydrogen, and methane. Gasification reactions are usually carried out at higher temperatures (800-1500℃). Existing pyrolysis gasification furnaces often use vertically distributed pyrolysis and gasification chambers to complete pyrolysis and gasification respectively. Waste enters the pyrolysis chamber for pyrolysis and falls into the gasification chamber for gasification.

[0003] Existing pyrolysis gasifiers have certain shortcomings during pyrolysis. The waste material often does not stay in the pyrolysis chamber for long enough before falling into the gasification chamber, failing to undergo sufficient pyrolysis and thus affecting the subsequent gasification process. If the pyrolysis time is extended by increasing the waste material displacement length, it is easy to cause adhesion and blockage if the waste material has a certain degree of stickiness, such as sludge. Therefore, a new pyrolysis gasifier needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a sludge pyrolysis gasification furnace to solve the problems mentioned in the background art, such as insufficient pyrolysis of wastes inside the pyrolysis chamber and the easy blockage and adhesion of wastes like sludge.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figures 1 to 5 This embodiment provides a technical solution: a sludge pyrolysis gasification furnace, comprising...

[0030] The gasification chamber 100 and the receiving port 600 located at the top of the gasification chamber 100 are used to gasify sludge.

[0031] The pyrolysis chamber 200 includes a chamber 201 located at the top of the gasification chamber 100, guide plates 202 fixed to the inner wall of the chamber 201 and distributed from top to bottom, and a discharge port 204 located at the bottom of the chamber 201 and aligned with the receiving port 600. The sludge entering the chamber 201 falls onto the guide plates 202 and slides down the surface of the guide plates 202 layer by layer. During this process, it is fully pyrolyzed and finally discharged from the discharge port 204.

[0032] The feed inlet 300 connected to the top of the pyrolysis chamber 200 allows sludge to be fed into the interior of the pyrolysis chamber 200.

[0033] The drive assembly 400 includes a pneumatic pump 401 fixedly connected between the top of the gasification chamber 100 and the bottom of the chamber 201, a stainless steel corrugated pipe 402 fixedly connected between the gasification chamber 100 and the chamber 201 and located outside the discharge port 204 and the receiving port 600, and a connecting pile 403 fixedly on the top of the gasification chamber 100 and sleeved on the bottom of the chamber 201. During the pyrolysis of sludge in the pyrolysis chamber 200, the pneumatic pump 401 can intermittently lift the chamber 201 suddenly and then quickly lower it, forming an intermittent up-and-down vibration, thereby preventing sludge from clogging, sticking, or condensing on the guide plate 202. The stainless steel corrugated pipe 402 can adapt to the vertical displacement of the chamber 201 and has good heat resistance and sealing performance. The connecting pile 403 can limit the position of the chamber 201 to a certain extent and improve the stability of the vertical displacement of the chamber 201.

[0034] In this embodiment, preferably, all guide plates 202 are inclined surfaces, with the end of the lowest guide plate 202 pointing towards the discharge port 204, allowing the sludge to slide directly from the lowest guide plate 202 to the discharge port 204.

[0035] In this embodiment, preferably, the pyrolysis cavity 200 further includes a ramp 203, which is disposed at the bottom of the cavity 201. The ramp 203 can prevent sludge residue from remaining at the bottom of the cavity 201.

[0036] In this embodiment, preferably, the pyrolysis cavity 200 further includes an electric heating plate 205, which is disposed on the inner wall of the cavity 201. When the electric heating plate 205 is energized, it generates high heat, forming a high-temperature environment inside the pyrolysis cavity 200.

[0037] In this embodiment, preferably, the drive assembly 400 further includes heat insulation cotton 408, which is fixed between the vaporization inner cavity 100 and the cavity 201 and wrapped around the outside of the stainless steel corrugated pipe 402 to further improve the heat insulation effect.

[0038] In this embodiment, preferably, the drive assembly 400 further includes a shock absorber 407, which is fixed at the top of the vaporization cavity 100 and located below the cavity 201, and can absorb shock when the cavity 201 falls.

[0039] In this embodiment, preferably, the drive assembly 400 further includes a side block 404 symmetrically fixed on the outer side of the bottom end of the cavity 201, and a side groove 405 formed on the inner wall of the connecting pile 403 and slidably inserted into the side block 404, to further improve the stability of the vertical displacement of the cavity 201.

[0040] In this embodiment, preferably, the drive assembly 400 further includes a bolt A406, and the bottom end of the connecting pile 403 is fixedly connected to the gasification cavity 100 by the bolt A406, so that the connecting pile 403 is detachably fixedly connected.

[0041] In this embodiment, preferably, an electrical control box assembly 500 is provided on one side of the vaporization cavity 100. The electrical control box assembly 500 includes an electrical control box 501, a damping shaft 502, and a fixing plate 503. The fixing plate 503 is rotatably connected to one side of the vaporization cavity 100 through the damping shaft 502. The fixing plate 503 is connected to the electrical control box 501. When the device is in use, the electrical control box 501 can be rotated to avoid it getting too close to the vaporization cavity 100, thus avoiding the adverse effects of high temperature.

[0042] In this embodiment, preferably, the electrical control box assembly 500 further includes a spiral wire 504 connected to the top of the electrical control box 501, a fixing piece 505 fixed to one end of the fixing plate 503, a bolt B507 that fixes the fixing piece 505 and the electrical control box 501, and a magnetic strip 506 fixed to one side of the vaporization cavity 100. The spiral wire 504 can complete the electrical connection between the electrical control box 501 and the electrical components on the device, and at the same time, it has elasticity to adapt to the opening or closing of the electrical control box 501. After the electrical control box 501 is closed, the magnetic strip 506 is attracted to the fixing piece 505 to ensure the stability of the electrical control box 501.

[0043] Working Principle: After starting the device, sludge is fed into the cavity 201 through the inlet 300. The sludge falls onto the guide plates 202. Since the guide plates 202 are all inclined, the sludge slides down the surface of the guide plates 202 layer by layer. The design of multiple guide plates 202 prolongs the residence time of the sludge inside the cavity 201, thereby allowing the sludge to be fully pyrolyzed. During the pyrolysis process, the pneumatic pump 401 can intermittently push the cavity 201 to move rapidly and then fall rapidly, forming an intermittent up-and-down vibration. Through vibration, the sludge can be effectively prevented from clogging, sticking, and coagulating on the guide plates 202, allowing the pyrolyzed sludge to fall smoothly from the discharge port 204 into the receiving port 600, and finally into the gasification inner cavity 100. The stainless steel corrugated pipe 402 set between the outer sides of the discharge port 204 and the receiving port 600 has good ductility to adapt to the cavity 201. The device vibrates up and down, and seals and isolates the discharge port 204 and the receiving port 600 to prevent the leakage of high-temperature airflow. The heat insulation cotton 408 further improves the heat insulation effect. When the cavity 201 is lifted by the pneumatic pump 401 and falls quickly, the shock absorber 407 can buffer and protect the cavity 201 from falling, preventing the impact force generated by the fall from being too large and damaging the entire device. When the cavity 201 moves, the side block 404 moves synchronously inside the side groove 405 to ensure that the cavity 201 vibrates up and down stably. Personnel can control the device through the electrical control box 501. Before use, the electrical control box 501 can be flipped over using the damping shaft 502 and the fixing plate 503 to prevent the electrical control box 501 from being too close to the device, so as to prevent the high temperature on the surface of the device from damaging the components inside the electrical control box 501. When not in use, the electrical control box 501 can be folded and retracted to avoid occupying space.

[0044] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
