Description

Technical fields:

[0001] This utility model relates to the field of gasification furnace technology, and in particular to a distilled water pyrolysis combustion aid device. Background technology:

[0002] Existing gasifiers primarily burn biomass fuels, low-rank coal, and solid waste fuels. These fuels have a high moisture content, and upon entering the furnace, they exchange heat with the rising hot combustion gas, causing the moisture in the fuel to evaporate. This results in a large amount of water vapor that cannot be released from the furnace. The evaporation of this moisture consumes a significant amount of heat generated by fuel combustion, leading to a decrease in furnace temperature and incomplete combustion. This, in turn, consumes a large amount of fuel and significantly increases the operating costs of the equipment. Utility model content:

[0003] The technical problem to be solved by this utility model is to provide a distilled water pyrolysis combustion aid device. This device realizes the condensation of water vapor in the gasifier into distilled water, effectively discharges the distilled water, and decomposes the water droplets into hydrogen and oxygen through the high-temperature pyrolysis chamber to participate in combustion and increase the flame temperature.

The guide plate extends into the annular liquid storage tank, and the outer wall of the guide plate is connected and sealed to the outer wall of the annular liquid storage tank by a connector.

[0007] The pyrolysis device includes a pyrolysis inner shell and a pyrolysis outer shell.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed implementation method:

[0022] like Figure 1 As shown, a distilled water pyrolysis combustion aid device includes a flow guiding mechanism, a liquid storage chamber, and a pyrolysis device;

[0023] The flow guiding mechanism includes a conical flow guiding plate 1 disposed at the top of the furnace, and the lower end of the conical flow guiding plate 1 is connected to a flow guide plate 3;

[0024] The liquid storage chamber includes an annular liquid storage tank 2. The bottom end of the annular liquid storage tank 2 is connected to the upper end of the side wall of the furnace. The guide plate 3 extends into the annular liquid storage tank 2. The outer wall of the guide plate 3 and the outer wall of the annular liquid storage tank 2 are connected and sealed by a connector 4.

[0025] The pyrolysis device includes a pyrolysis inner shell 7 and a pyrolysis outer shell 8. The pyrolysis outer shell 8 is fitted outside the pyrolysis inner shell 7. The space between the pyrolysis outer shell 8 and the pyrolysis inner shell 7 forms a pyrolysis chamber. The pyrolysis inner shell 7 has a connecting channel that communicates with the pyrolysis chamber. The pyrolysis inner shell 7 is connected to the gasification combustion chamber 9 and the interlayer flue 11 surrounding the outside of the furnace wall.

[0026] The liquid storage chamber is connected to the pyrolysis chamber via a flow guide pipe 5. A flow controller 6 is installed on the flow guide pipe 5, and the flow controller 6 can control the flow rate in real time according to the temperature inside the pyrolysis chamber.

[0027] The upper end of the conical guide plate 1 is connected to the fuel tank.

[0028] The drainage plate 3 is a vertical plate.

[0029] The annular liquid storage tank 2 includes an annular inner wall and an annular outer wall. The annular outer wall is located outside the annular inner wall, and the bottom end of the annular outer wall is connected to the bottom end of the annular inner wall through an annular bottom plate.

[0030] The connecting component 4 is a flange.

[0031] The conical guide plate 1 and the diversion plate 3 are made of alloy steel.

[0032] The annular liquid storage tank 2 is made of alloy steel.

[0033] The pyrolysis device is made of alloy steel.

[0034] The flow controller 6 includes a detection unit, a control unit, and an execution unit. The detection unit includes a temperature sensor capable of detecting the internal temperature of the pyrolysis chamber. The control unit includes a controller. The execution unit includes an electric actuator and a flow regulating valve. The temperature sensor monitors the internal temperature of the pyrolysis chamber in real time and transmits the temperature signal to the controller. The controller compares the actual temperature inside the pyrolysis chamber with the set temperature and then outputs a command to control the electric actuator to drive the flow regulating valve to increase its opening. If the actual temperature > the set value: the water flow is increased, the controller outputs an increase signal, the electric actuator drives the flow regulating valve to increase its opening, and the water flow increases. If the temperature < the set value: the water flow is decreased, the controller outputs a decrease signal, the electric actuator drives the flow regulating valve to decrease its opening, and the water flow decreases.

[0035] During operation, the rising hot steam inside the furnace meets the newly introduced fuel in the drying layer, undergoing heat exchange. This causes the moisture in the fuel to evaporate, generating a large amount of water vapor. The rising water vapor condenses into distilled water upon contact with the conical guide plate 1. The distilled water flows along the conical guide plate 1 and the guide plate 3 into the annular storage tank 2, and then through the guide pipe 5 and flow controller 6 into the pyrolysis chamber. The gasified gas in the gasification chamber 10 enters the gasification combustion chamber 9 for combustion, causing the pyrolysis inner shell 7 connected to the gasification combustion chamber 9 to reach a high temperature. The flow controller 6 controls the flow rate of distilled water via a temperature sensor, ensuring that a certain amount of distilled water enters the high-temperature pyrolysis chamber. The distilled water undergoes high-temperature pyrolysis in the pyrolysis chamber, producing hydrogen and oxygen. The hydrogen and oxygen enter the gasification combustion chamber 9 through the connecting channels on the pyrolysis inner shell 7 to participate in combustion, increasing the flame temperature.
