Description

Technical Field

[0001] This utility model belongs to the field of organic heat carrier furnace technology, and in particular relates to an energy-saving combustion device for organic heat carrier furnaces. Background Technology

[0002] Organic heat carrier furnaces, also known as thermal oil furnaces, are a new type of thermal energy equipment that uses organic heat carriers (thermal oil) as the heat transfer medium. They play a key role in heat supply in industrial production and are widely used in many fields such as chemical industry, textile industry, and printing and dyeing industry.

[0003] However, traditional organic heat carrier furnaces suffer from low energy efficiency and inaccurate combustion control during operation. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an energy-saving combustion device for an organic heat carrier furnace. An oxygen content sensor at the flue gas outlet monitors the oxygen content in the flue gas in real time and transmits the data to an external central controller. Based on preset control logic and oxygen content data, the external central controller controls the opening of the fuel flow regulating valve and the air flow regulating valve, dynamically adjusting the flow rates of fuel and combustion air to ensure that combustion is always in a highly efficient and complete state, avoiding incomplete combustion caused by excessive fuel, and improving energy utilization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An energy-saving combustion device for an organic heat carrier furnace includes a furnace body; a fixed plate is fixed inside the furnace body, an oil chamber is located above the fixed plate, and a combustion chamber is located below the fixed plate; an oil inlet pipe extending into the oil chamber is fixed to the left side of the furnace body; a high-temperature oil pump is installed on the right side of the furnace body, and an oil outlet pipe is fixed at the oil inlet of the high-temperature oil pump, extending to the bottom of the oil chamber; a fuel inlet pipe extending into the combustion chamber is fixed to the right bottom end of the furnace body, and a fuel flow regulating valve is fixed to the fuel inlet pipe; an air inlet pipe extending into the combustion chamber is fixed to the left bottom end of the furnace body, and an air flow regulating valve is fixed to the air inlet pipe. The combustion chamber is equipped with a regulating valve, an igniter fixed to the bottom surface, and an exhaust pipe extending above the combustion chamber on the left side of the furnace body. An oxygen content sensor is fixed at the exhaust pipe outlet. The oxygen content sensor at the exhaust pipe outlet monitors the oxygen content in the flue gas in real time and transmits the data to an external central controller. Based on preset control logic and oxygen content data, the external central controller controls the opening of the fuel flow regulating valve and the air flow regulating valve, dynamically adjusting the flow rates of fuel and combustion air to ensure that combustion is always in a highly efficient and complete state, avoiding incomplete combustion due to excessive fuel, and improving energy utilization.

[0006] Furthermore, the furnace body sidewall is provided with a heat insulation cavity, which is filled with heat insulation cotton. The heat insulation cotton in the heat insulation cavity of the furnace body sidewall effectively blocks the heat exchange between the furnace body and the external environment, reduces the heat loss of the furnace body to the surrounding environment, reduces the additional energy consumption caused by heat loss, and improves the economic efficiency of equipment operation.

[0007] Furthermore, the output of the oxygen content sensor is electrically connected to an external central controller via a wire, and the output of the external central controller is electrically connected to the fuel flow regulating valve and the air flow regulating valve via wires respectively. Based on the intelligent control system of the sensor and the external central controller, the combustion process is automated and precise, eliminating the need for frequent manual intervention by operators, reducing the intensity and error of manual operation, and facilitating centralized management and remote monitoring of the equipment.

A valve 8 is installed, and an igniter 9 is fixed to the bottom surface of the combustion chamber 3. A flue pipe 10 extending above the combustion chamber 3 is fixed to the left side of the furnace body 1. An oxygen content sensor 11 is fixed at the outlet of the flue pipe 10. The oxygen content sensor 11 at the outlet of the flue pipe 10 monitors the oxygen content in the flue gas in real time and transmits the data to an external central controller. Based on the preset control logic and oxygen content data, the external central controller controls the opening of the fuel flow regulating valve 6 and the air flow regulating valve 8 to dynamically adjust the flow of fuel and combustion air, ensuring that combustion is always in a highly efficient and complete state, avoiding incomplete combustion caused by excessive fuel, and improving energy utilization.

[0015] A heat insulation cavity is provided on the side wall of the furnace body 1. The heat insulation cotton 14 is provided in the heat insulation cavity of the side wall of the furnace body 1, which effectively blocks the heat exchange between the furnace body 1 and the external environment, reduces the heat loss of the furnace body 1 to the surrounding environment, reduces the extra energy consumption caused by heat loss, and improves the economic efficiency of equipment operation.

[0016] The output of the oxygen content sensor 11 is electrically connected to the external central controller via a wire. The output of the external central controller is electrically connected to the fuel flow regulating valve 6 and the air flow regulating valve 8 via wires, respectively.

[0017] Working Principle: During operation of the organic heat carrier furnace, fuel is transported through fuel inlet pipe 5, and the amount of fuel entering combustion chamber 3 is controlled by fuel flow regulating valve 6. Combustion air is transported through air inlet pipe 7, and the amount of air entering combustion chamber 3 is regulated by air flow regulating valve 8. The fuel and air entering combustion chamber 3 undergo a combustion reaction under the action of igniter 9, releasing heat. The heat generated by combustion is transferred upwards to heat the organic heat carrier in oil chamber 2 above fixed plate 4. The heated organic heat carrier is then transported to the heat-using equipment through high-temperature oil pump 13 and oil drain pipe. The flue gas generated by combustion is discharged through flue pipe 10. Oxygen content sensor 11 at the outlet of flue pipe 10 monitors the oxygen content in the flue gas in real time and transmits the data to an external central controller. Based on preset control logic and oxygen content data, the external central controller controls the opening of fuel flow regulating valve 6 and air flow regulating valve 8, dynamically adjusting the flow rates of fuel and combustion air to ensure that combustion is always in a highly efficient and complete state, avoiding incomplete combustion due to excessive fuel, and improving energy utilization. Meanwhile, insulation cotton 14 is installed in the insulation cavity of the side wall of the furnace body 1, which effectively blocks the heat exchange between the furnace body 1 and the external environment, reduces the heat loss of the furnace body 1 to the surrounding environment, reduces the extra energy consumption caused by heat loss, and improves the economic efficiency of equipment operation.
