Description

Technical Field

[0001] This utility model belongs to the field of combustion equipment technology, and specifically relates to a high-temperature combustion chamber. Background Technology

[0002] A carbonization furnace is a device that performs dry distillation and anaerobic carbonization of carbon-containing wood under high-temperature conditions. During the carbonization process, large amounts of combustible gases such as carbon monoxide, methane, and oxygen are produced. These gases must be burned in a high-temperature combustion chamber before being released; direct emission would cause significant environmental pollution. Existing high-temperature combustion chambers, due to insufficient temperature control, cannot achieve complete combustion of the waste gases produced by the carbonization furnace, and some incompletely burned waste gas is still emitted, failing to meet environmental protection requirements. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a high-temperature combustion chamber. This high-temperature combustion chamber is used to burn the waste gas generated by the carbonization furnace at high temperatures. The waste gas undergoes oxygen-deficient combustion within the high-temperature combustion chamber. The combustion chamber is equipped with an insulation layer consisting of four layers: wear-resistant castable, lightweight castable, ceramic fiber blanket, and nano-board, from the inside out. This design can maintain the temperature inside the combustion chamber at 900-1200℃, ensuring that most of the waste gas is completely burned. A portion of the combustible waste gas is transported to other equipment for secondary utilization through the gas outlet.

[0004] To achieve the above technical objectives, the technical solution adopted in this utility model embodiment is as follows:

[0005] A high-temperature combustion chamber, wherein the outlet end of the combustion chamber is provided with an explosion-proof door and a gas outlet;

[0006] The combustion chamber is provided with a burner interface at its inlet end, and the combustion chamber is connected to the burner through the burner interface. The combustion chamber is also provided with a gas inlet, an air inlet, an acrylic glass observation port, and a flame detector port at its inlet end.

[0007] The top of the combustion chamber is equipped with a first thermocouple, a second thermocouple, and a pressure gauge. The first thermocouple is used to detect the temperature at the inlet of the combustion chamber, the second thermocouple is used to detect the temperature at the outlet of the combustion chamber, and the pressure gauge is used to detect the pressure at the outlet of the combustion chamber.

[0008] Adjust the burner parameters and the flow rates of gas and air in and out based on the readings of the first thermocouple, the second thermocouple, and the pressure gauge to ensure that the temperature in the combustion chamber is maintained at 900-1200℃.

[0009] Furthermore, the explosion-proof door and burner interface are located at both ends of the combustion chamber, the plexiglass observation port is located at the top of the combustion chamber, and the flame detector port is located on the combustion chamber shell below the plexiglass observation port;

[0010] The gas outlet, gas inlet, and air inlet are all located on the shell of the combustion chamber.

[0011] Furthermore, the top of the combustion chamber has an arched structure.

[0012] Furthermore, the combustion chamber shell is provided with four insulation layers inside, which are, from the inside out, wear-resistant castable, lightweight castable, ceramic fiber blanket and nanoplate.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment are:

[0014] The high-temperature combustion chamber of this invention is used to burn the waste gas generated by the carbonization furnace at high temperature. The waste gas undergoes oxygen-deficient combustion in the high-temperature combustion chamber. The combustion chamber is equipped with an insulation layer, which consists of four layers: wear-resistant castable, lightweight castable, ceramic fiber blanket and nanoplate, from the inside to the outside. This design can maintain the temperature in the combustion chamber at 900-1200℃, so as to burn the waste gas cleanly.

[0015] The gas enters the combustion chamber through the gas inlet, and the air entering through the air inlet can control the temperature inside the combustion chamber. After high-temperature combustion in the combustion chamber, most of the waste gas can be burned cleanly, and some combustible waste gas is transported to other equipment for secondary utilization through the gas outlet.

[0016] The installation of the first thermocouple, the second thermocouple, and the pressure gauge enables real-time monitoring of the temperature and pressure inside the combustion chamber, and adjusts the temperature and pressure inside the combustion chamber by controlling the flow of gas and air to prevent combustion chamber explosion.
