Combustion exhaust gas fired heating furnace

Abstract

A combustible waste gas combustion and heating furnace consists of a multi-combustion chamber and a hot air outlet pipe. This invention utilizes carbon monoxide gas generated during the carbonization process of environmentally friendly charcoal and charcoal powder. This carbon monoxide gas is introduced into the furnace chamber for combustion via a suction fan, effectively preventing incomplete combustion from being carried away by the wind, thus avoiding gas loss and air pollution. The secondary combustion and heating chamber of this invention consists of several high-alumina refractory bricks stacked in a triangular pattern to form several secondary combustion ventilation openings, creating a honeycomb wall. When water vapor enters the multi-combustion chamber, it is rapidly absorbed by the high-temperature honeycomb wall. This allows for 24 hours of operation without the need for any combustion aids, achieving a furnace temperature exceeding 1800 degrees Celsius. This invention is mainly used for smelting, drying materials, firing ceramic bricks, thermal power generation, and high-temperature material heating; it can replace coal and natural gas, meets the national requirements for biomaterial thermal energy, and is safe and pollution-free.

Description

Technical Field

[0001] This invention pertains to an energy-saving device, specifically a combustible waste gas combustion heating furnace. Background Technology

[0002] A waste gas incinerator is a device that uses the heat generated by the combustion of auxiliary fuel to raise the temperature of combustible and harmful gases to the reaction temperature, thereby causing oxidative decomposition. Waste gas incinerators are suitable for treating waste gases from spraying and drying equipment, as well as purifying harmful gases emitted from industries such as petrochemicals and pharmaceuticals. They are particularly advantageous for purifying organic waste gases containing water-soluble or viscous substances and high molecular weight compounds. They meet environmental protection and occupational safety requirements, and with the addition of heat exchange equipment, can achieve waste heat recovery and energy savings.

[0003] However, current incinerators are generally quite expensive, which many small and medium-sized enterprises cannot afford.

[0004] Furthermore, waste gas incinerators are effective devices for preventing the volatilization of organic solvents into the atmosphere and causing environmental pollution. If these waste gases are collected during production and incinerated in a waste gas incinerator, the organic solvents are oxidized and decomposed into H2O and CO2 before being released, thus preventing environmental pollution. Environmental protection has received increasing attention from all sectors of society. Therefore, most factories have installed waste gas incinerators to treat the organic waste gases generated during production. The condition for the complete oxidation and decomposition of organic matter (including benzene-containing compounds such as phenol) is that the oxidation temperature must reach above 760℃. Therefore, to ensure that the exhaust gas emitted after combustion in the waste gas incinerator does not pollute the environment, the combustion temperature of the waste gas incinerator must reach 760℃. Since the higher the temperature of the incinerator furnace, the more fuel is consumed. Some factories, in order to save fuel and reduce production costs, adopt low-temperature combustion methods, that is, furnace temperatures below 760℃ (such as 700℃, or even below 600℃). This results in the incomplete oxidation and decomposition of organic solvents or other harmful components (such as phenol, formaldehyde, etc.). The levels of these harmful components exceeding national standards can be detected on the incinerator's exhaust chimney. The odor and drifting particles of these organic substances can be smelled within hundreds of meters of the incinerator. Therefore, to ensure that the waste gas generated during the production of these products does not pollute the environment: (1) a waste gas incinerator or other organic matter recovery and treatment device must be established; (2) the combustion temperature of the waste gas incinerator furnace must reach above 760℃. Summary of the Invention

[0005] The purpose of this invention is to provide a novel combustible waste gas combustion heating furnace. Specifically, the furnace consists of a multi-stage combustion chamber (1) and a hot air outlet pipe (2).

[0006] This invention is achieved through the following technical solution:

[0007] A combustible waste gas combustion heating furnace, wherein the furnace is composed of a multi-combustion chamber (1) and a hot air outlet pipe (2).

[0008] The multi-combustion chamber (1) consists of a primary combustion chamber (3), a fire baffle (4), a secondary combustion heating chamber (5), a dust storage chamber (6), an oxygen inlet (7), and a base (8). A furnace door (9) and a gas inlet (10) are provided at the front end of the primary combustion chamber (3), a gas outlet (11) is provided at the rear end of the dust storage chamber (6), an ash outlet (12) is provided at the bottom of the dust storage chamber (6), and a grate (13) is provided at the top of the oxygen inlet (7). The fire baffle (4) is located inside the primary combustion chamber (3), and the secondary combustion heating chamber (5) is formed by stacking several high-alumina refractory bricks (14) in a triangular pattern to form several secondary combustion ventilation openings (15).

[0009] The hot air outlet pipe (2) is provided with a gas inlet (16) and a gas outlet (17).

[0010] When the above-mentioned multiple combustion chamber (1) and hot air outlet pipe (2) are combined, the gas inlet (16) at the front end of the hot air outlet pipe (2) is connected to the gas outlet (11) at the rear end of the dust storage chamber (6) of the multiple combustion chamber (1), thereby forming a combustible waste gas combustion heating furnace as a whole.

[0011] The present invention has the following advantages:

[0012] 1. The present invention has a novel and unique structure, and its design is scientific and reasonable.

[0013] 2. This invention utilizes the carbon monoxide gas generated during the carbonization process of environmentally friendly charcoal and charcoal powder. The gas is introduced into the furnace cavity for combustion through a suction fan, which effectively avoids the gas being carried away by the wind before it can be fully burned, thus preventing gas loss and air pollution.

[0014] 3. In this invention, the core part is the multiple combustion chamber (1), and the rear secondary combustion heating chamber (5) is formed by stacking several high-alumina refractory bricks (14) in a triangular pattern to form several secondary combustion ventilation openings (15), creating honeycomb wall holes. When the combustion furnace is working, the wall will be heated to a certain temperature in a short time when the flame passes through the honeycomb wall holes. The gas that was not completely burned in the primary combustion chamber (3) will be fully burned a second time when it passes through the honeycomb wall formed by the secondary combustion heating chamber (5), and the temperature in the furnace will rise again. The honeycomb wall of the secondary combustion heating chamber (5) also plays a role in heat preservation and temperature control. During the carbonization process of biological materials, there is a large amount of water vapor. When the water vapor enters the multiple combustion chamber (1), it will be quickly absorbed by the high-temperature honeycomb wall. It can reach a temperature of over 1800 degrees Celsius for 24 hours without the need for any combustion aids.

[0015] 4. The present invention is mainly used for smelting, drying materials, firing ceramic bricks, generating thermal power, and heating with high-temperature materials; it can replace coal and natural gas, meets the national requirements for biomaterial thermal energy, and is safe and free from air pollution.
