[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on March 10, 2023, with application number 202310228502.9 and invention name “Pyrolysis Furnace”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The utility model relates to the technical field of biomass pyrolysis, in particular to a pyrolysis furnace for pyrolyzing biomass. Background Art

[0003] At present, when using an existing pyrolysis furnace to burn charcoal, after the charcoal is burned, it is usually necessary to cool naturally before removing the charcoal from the pyrolysis furnace. The cooling process takes a long time, resulting in low charcoal burning efficiency. Utility Model Content

[0004] In order to improve the efficiency of charcoal burning, the utility model proposes a pyrolysis furnace, which includes a furnace body and a water supply system. The water supply system includes a water outlet pipe, which is located in the inner cavity of the furnace body and close to the top of the furnace body, and a water outlet is provided on the water outlet pipe. In this way, after the charcoal is burned, the water outlet pipe in the water supply system can be used to spray water into the furnace body. When the temperature in the furnace is higher than 270°C, the sprayed water and charcoal are pyrolyzed in a high temperature environment to produce CO and H2, and the pyrolysis consumes energy to reduce the temperature in the furnace; when the temperature in the furnace is reduced to below 270°C, the sprayed water vaporizes and cools down, further reducing the temperature in the furnace. It can be seen that when using the pyrolysis furnace of the utility model to burn charcoal, compared with natural cooling, using the water outlet pipe of the water supply system to spray water into the furnace body can quickly reduce the temperature in the furnace body and improve the burning efficiency of charcoal.

[0005] Preferably, the central axis of the water outlet pipe is parallel to the central axis of the furnace body, and the water outlet pipe is provided with a plurality of water outlets. In this way, the water outlet pipe is simple and convenient to install, and the water outlet pipe can spray water into the furnace body through a plurality of water outlets at the same time, which can improve the water spraying efficiency, improve the cooling speed, and thus improve the charcoal burning efficiency. Further, a spray head is provided on the water outlet pipe, and the water inlet of the spray head is connected to the water outlet on the water outlet pipe. In this way, the spray head connected to the water outlet is provided on the water outlet pipe, which can improve the atomization degree of the water sprayed into the furnace body, thereby improving the vaporization speed of the sprayed water mist, and thus improving the cooling speed inside the furnace body and the charcoal burning efficiency. Further preferably, the spray heads are evenly distributed on the water outlet pipe along the extension direction of the water outlet pipe. In this way, the water outlet pipe can spray the water mist evenly into the furnace body through the spray head, thereby improving the pyrolysis efficiency and cooling efficiency of the water mist and high-temperature charcoal.

[0006] Preferably, the water supply system includes a temperature detection device and a water inlet valve, wherein the temperature detection device is installed in the furnace body for real-time monitoring of the temperature in the furnace body, and the water inlet valve is installed on a water supply pipe connected to the water outlet pipe for controlling the water inlet of the water outlet pipe. In this way, when using the pyrolysis furnace of the utility model to burn charcoal, the working state of the water inlet valve can be controlled according to the temperature of the furnace body monitored in real time by the temperature detection device, thereby controlling the working state of the water supply system, which is convenient for control. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a structural schematic diagram of the pyrolysis furnace of the utility model. DETAILED DESCRIPTION

[0008] Next, combine Figure 1 , the pyrolysis furnace of the utility model is described in detail.

[0009] like Figure 1 As shown, the pyrolysis furnace of the utility model includes a furnace body 1 and a water supply system, and the water supply system includes a water outlet pipe 21, which is located in the inner cavity of the furnace body 1 and close to the top of the furnace body 1, and a water outlet is provided on the water outlet pipe 21 (not shown in the figure). In this way, after the charcoal is burned, the water outlet pipe 21 in the water supply system can be used to spray water into the furnace body 1. When the temperature in the furnace is higher than 270°C, the sprayed water and charcoal are pyrolyzed in a high temperature environment to produce CO and H2, and the pyrolysis consumes energy to reduce the temperature in the furnace; when the temperature in the furnace is reduced to below 270°C, the sprayed water vaporizes and cools down, further reducing the temperature in the furnace. It can be seen that when using the pyrolysis furnace of the utility model to burn charcoal, compared with natural cooling, using the water outlet pipe of the water supply system to spray water into the furnace body can quickly reduce the temperature in the furnace body and improve the burning efficiency of charcoal. Preferably, the central axis of the water outlet pipe 21 is parallel to the central axis of the furnace body 1, and a plurality of water outlets are provided on the water outlet pipe 21. In this way, the water outlet pipe 21 is easy and convenient to install, and the water outlet pipe 21 can spray water into the furnace body 1 through multiple water outlets at the same time, which can improve the water spraying efficiency, improve the cooling speed, and thus improve the charcoal burning efficiency. Preferably, a spray head 22 is provided on the water outlet pipe 21, and the water inlet of the spray head 22 is connected to the water outlet on the water outlet pipe 21. In this way, the spray head 22 connected to the water outlet is provided on the water outlet pipe 21, which can improve the atomization degree of the water sprayed into the furnace body 1, thereby improving the vaporization speed of the sprayed water mist, and thus improving the cooling speed inside the furnace body 1 and the charcoal burning efficiency. Preferably, the spray heads 22 are evenly distributed on the water outlet pipe 21 along the extension direction of the water outlet pipe 21. In this way, the water outlet pipe 21 can spray the water mist evenly in the furnace body 1 through the spray head 22, thereby improving the pyrolysis efficiency and cooling efficiency of the water mist and high-temperature charcoal.

[0010] The water supply system includes a temperature detection device (not shown in the figure) and a water inlet valve (not shown in the figure). The temperature detection device is installed in the furnace body 1 for real-time monitoring of the temperature in the furnace body 1. The water inlet valve is installed on the water supply pipe 23 connected to the water outlet pipe 21 to control the water inlet of the water outlet pipe 21. In this way, when using the pyrolysis furnace of the utility model to burn charcoal, the working state of the water inlet valve can be controlled according to the temperature of the furnace body monitored in real time by the temperature detection device, thereby controlling the working state of the water supply system, which is convenient for control. Preferably, a high temperature resistant temperature sensor can be used as the temperature detection device to monitor the temperature of the furnace body in real time.
