Description

Technical Field

[0001] This utility model relates to the field of organic heat carrier furnace technology, and in particular to an organic heat carrier furnace structure. Background Technology

[0002] With industrial development, the demand for energy is constantly increasing, while environmental protection requirements are becoming increasingly stringent. Organic heat carrier furnaces, as a highly efficient heat energy conversion device, are widely used in industries such as chemical, pharmaceutical, and food processing. They transfer heat to heat-using equipment through organic heat carriers (such as heat transfer oil), offering advantages such as high thermal efficiency and ease of operation.

[0003] Although existing organic heat carrier boilers have made some progress in heat recovery and utilization, there is still a problem of heat loss, especially at the connection between the boiler body and the pipeline, which prevents further improvement in thermal efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an organic heat carrier furnace structure.

[0005] This utility model is achieved using the following technical solution: an organic heat carrier furnace structure, including a boiler body, a chain body drivingly connected to the bottom end of the boiler body, a furnace wall fixedly connected to the bottom end of the boiler body, a waste heat boiler provided at the right end of the boiler body, a flue gas duct fixedly connected to the right end of the boiler body, a waste heat boiler fixedly connected to the right end of the flue gas duct, and rock wool insulation material fixedly connected to the inner wall of the waste heat boiler.

[0006] Through the above technical solution, the boiler body is the core of the entire system. It generates heat through fuel combustion, which heats the organic heat carrier (such as heat transfer oil) to provide thermal energy for other equipment or processes. The chain body is located at the bottom of the boiler body and can be used to transport materials such as fuel, so that the fuel can continuously and stably enter the boiler body for combustion, ensuring continuous heat generation. The furnace wall can effectively isolate the interior of the boiler body from the external environment, reduce heat loss, improve the thermal efficiency of the boiler, and also prevent the heat radiation impact on the surrounding environment, which has certain environmental protection significance. The waste heat boiler is connected to the boiler body through the flue gas duct, which can make full use of the waste heat generated by the boiler body. The heat is transferred to the waste heat boiler to heat the medium (such as water) inside the waste heat boiler, producing usable energy forms such as steam or hot water, thereby improving the energy utilization rate.

[0007] As a further improvement to the above solution, an air preheater is fixedly connected to the right end of the waste heat boiler, and a pipe is fixedly connected to the right end of the air preheater. The right end of the pipe is fixedly connected to the left end of the ceramic multi-tube dust collector.

[0008] With the above technical solution, the air preheater is located at the right end of the waste heat boiler. It can transfer the heat from the flue gas coming out of the waste heat boiler to the incoming air, so that the air is preheated before entering the boiler body to participate in combustion, which improves combustion efficiency and reduces fuel consumption. By preheating the air, the fuel combustion is more complete, reducing the emission of incomplete combustion products and reducing environmental pollution. The ceramic multi-tube dust collector is connected to the right end of the air preheater through a pipeline, which can effectively filter and remove dust in the flue gas, reducing the amount of dust emitted into the atmosphere and meeting environmental protection requirements.

[0009] As a further improvement to the above scheme, a heat transfer oil inlet is fixedly connected to the right end of the boiler body, a heat transfer oil outlet is fixedly connected to the front end of the boiler body, and a flue gas outlet is fixedly connected to the right end of the boiler body.

[0010] Through the above technical solution, the heat transfer oil inlet is used to introduce heat transfer oil into the boiler body for heating, while the heat transfer oil outlet is used to transport the heated heat transfer oil to other equipment or processes, realizing the recycling of heat transfer oil, ensuring heat transfer and supply, facilitating the control and management of heat transfer oil flow, and also facilitating the maintenance of the heat transfer oil system. The flue gas outlet is used to discharge the flue gas generated by the boiler body and the waste heat boiler into the atmosphere, ensuring the normal operation of the boiler, facilitating the monitoring of flue gas emissions, such as flue gas temperature, flow rate, composition, etc., so as to adjust the boiler operating parameters in a timely manner and ensure its normal operation.

[0011] As a further improvement to the above scheme, a cleaning port is fixedly connected to the top of the boiler body, the right end of the furnace wall is hinged to the left end of the furnace door, the right end of the furnace wall is hinged to the left end of the furnace door, a drain port is fixedly connected to the right end of the boiler body, and a fire observation hole is opened at the front end of the furnace wall.

[0012] The above technical solutions facilitate operators in cleaning the boiler interior by setting up ash removal ports and ash removal doors, removing accumulated ash, ensuring the boiler's heat transfer efficiency and normal operation, and making it easier to inspect and maintain the boiler interior, and promptly detect and address any problems inside the boiler.

[0013] As a further improvement to the above scheme, a negative pressure detection pipe is fixedly connected to the front end of the furnace wall, a flue gas temperature measuring port is fixedly connected to the top of the boiler body, a secondary air duct is fixedly connected to the front end of the furnace wall, and an inert gas extinguishing port is fixedly connected to the front end of the furnace wall.

[0014] Through the above technical solution, the negative pressure detection tube monitors the pressure inside the furnace in real time, ensuring that the pressure inside the furnace is within a safe range and preventing safety accidents caused by abnormal pressure. When the negative pressure inside the furnace deviates from the normal range, the combustion status inside the furnace can be adjusted by regulating the air volume of the secondary air duct and other air intake devices to ensure stable pressure inside the furnace and maintain normal combustion and heat generation processes. The flue gas temperature measuring port is used to measure the temperature of the flue gas in order to understand the boiler's operating status in a timely manner, adjust the boiler's operating parameters, and ensure its normal operation. By monitoring the flue gas temperature, safety accidents such as fires and explosions caused by excessively high flue gas temperatures can be prevented. In the event of an emergency such as a fire, inert gas can be injected into the furnace through the inert gas extinguishing port to suppress combustion, prevent the fire from spreading, improve equipment safety, and provide an effective fire extinguishing means for dealing with possible fires and other emergencies.

[0015] As a further improvement to the above solution, a venting device interface is fixedly connected to the top of the boiler body, a furnace soot blowing device is fixedly connected to the top of the boiler body, the front end of the boiler body is hinged to the rear end of the soot cleaning door, and two soot cleaning doors are provided.

[0016] Through the above technical solution, the venting device interface has an interlocking function. When the furnace pressure or other related parameters are abnormal, the venting operation can be carried out in a timely manner to ensure the safe and stable operation of the entire organic heat carrier furnace structure and prevent equipment damage or safety accidents caused by excessive furnace pressure or other abnormal conditions.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model features a chain body connected to the bottom of the boiler body for material conveying and other related functions. Working in conjunction with the boiler body, it makes the entire organic heat carrier furnace structure more efficient. The boiler body and the waste heat boiler are connected through a flue. This layout can make full use of the waste heat generated by the flue gas in the boiler body and transfer the heat to the waste heat boiler, thereby improving energy utilization. The right end of the waste heat boiler is connected to an air preheater to further recover and utilize the heat, preheat the air, and reduce energy waste.

[0019] The rock wool insulation material fixedly connected to the inner wall of the waste heat boiler can effectively reduce heat loss and improve the thermal efficiency of the waste heat boiler. At the same time, it also reduces the impact of heat radiation on the surrounding environment, which has certain environmental protection significance. The right end of the air preheater is connected to the ceramic multi-tube dust collector through a pipe, which can effectively filter and remove dust in the flue gas, reduce the amount of dust emitted into the atmosphere, and meet environmental protection requirements.

[0020] This utility model, through components such as furnace door one, furnace door two, fire observation hole, ash cleaning port, and ash cleaning door installed on the furnace wall, facilitates operators to inspect, clean, and maintain the boiler interior, while also improving operational safety. The negative pressure detection pipe fixedly connected to the front end of the furnace wall can monitor the pressure inside the furnace in real time, ensuring that the pressure inside the furnace is within a safe range and preventing safety accidents caused by abnormal pressure. The venting device interface at the top of the boiler body has an interlocking function, which can promptly vent when the pressure inside the furnace or other related parameters are abnormal, ensuring the safe and stable operation of the entire organic heat carrier furnace structure. The inert gas extinguishing port at the front end of the furnace wall provides an effective fire extinguishing means to deal with possible fires and other emergencies, improving the safety of the equipment.

[0021] The heat transfer oil outlet at the front end and the heat transfer oil inlet at the right end of the boiler body facilitate the control and management of the flow of heat transfer oil, and also facilitate the maintenance of the heat transfer oil system. The flue gas outlet at the right end of the boiler body and the flue gas temperature measuring port at the top facilitate the monitoring of flue gas emissions and temperature, which helps to adjust the boiler's operating parameters in a timely manner and ensure its normal operation. The secondary air duct at the front end of the furnace wall facilitates the adjustment of the air intake, ensuring the completeness and stability of combustion, and also facilitates the maintenance of the secondary air system.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figure 1-4 An organic heat carrier furnace structure according to this embodiment includes a boiler body 1, a chain body 2 connected to the bottom end of the boiler body 1, a furnace wall 3 fixedly connected to the bottom end of the boiler body 1, a waste heat boiler 4 provided at the right end of the boiler body 1, a flue gas duct 7 fixedly connected to the right end of the boiler body 1, a waste heat boiler 4 fixedly connected to the right end of the flue gas duct 7, and rock wool insulation material 6 fixedly connected to the inner wall of the waste heat boiler 4.

[0031] An air preheater 5 is fixedly connected to the right end of the waste heat boiler 4. A pipe is fixedly connected to the right end of the air preheater 5. The right end of the pipe is fixedly connected to the left end of the ceramic multi-tube dust collector 8.

[0032] A heat transfer oil inlet 9 is fixedly connected to the right end of the boiler body 1, a heat transfer oil outlet 10 is fixedly connected to the front end of the boiler body 1, and a flue gas outlet 11 is fixedly connected to the right end of the boiler body 1.

[0033] The top of the boiler body 1 is fixedly connected to the ash removal port 12. The right end of the furnace wall 3 is hinged to the left end of the furnace door 13, and the right end of the furnace wall 3 is hinged to the left end of the furnace door 2 16.

[0034] A drain outlet 14 is fixedly connected to the right end of the boiler body 1, and a fire observation hole 15 is opened at the front end of the furnace wall 3.

[0035] A negative pressure detection pipe 17 is fixedly connected to the front end of the furnace wall 3, a flue gas temperature measuring port 18 is fixedly connected to the top of the boiler body 1, a secondary air duct 19 is fixedly connected to the front end of the furnace wall 3, and an inert gas extinguishing port 20 is fixedly connected to the front end of the furnace wall 3.

[0036] The boiler body 1 is fixedly connected to the top of the venting device interface 21 and the top of the boiler body 1 is fixedly connected to the furnace soot blowing device 22. The front end of the boiler body 1 is hinged to the rear end of the ash cleaning door 23, and there are two ash cleaning doors 23.

[0037] The implementation principle of an organic heat carrier furnace structure in this application embodiment is as follows: fuel burns inside the boiler body 1, releasing heat to heat the organic heat carrier (such as heat transfer oil) inside the boiler body 1. The heat transfer oil enters the boiler body 1 through the heat transfer oil inlet 9, absorbs heat, and flows out from the heat transfer oil outlet 10, providing heat energy for other equipment or processes. The flue gas generated by combustion carries a large amount of heat and flows through the flue duct 7 to the waste heat boiler 4. The flue gas entering the waste heat boiler 4 continues to release heat, heating the medium (such as water) inside the waste heat boiler 4 to produce usable energy forms such as steam or hot water. Rock wool insulation material 6 reduces the loss of heat from inside the waste heat boiler 4 to the outside, improving heat utilization efficiency. The flue gas from the waste heat boiler 4 continues to enter the air preheater 5, transferring heat to the incoming air, preheating the air before it enters the boiler body 1 to participate in combustion, improving combustion efficiency. After the air is preheated in the air preheater 5, the flue gas enters the ceramic multi-tube dust collector 8 through a pipe. The ceramic multi-tube dust collector 8 utilizes centrifugal force and other principles to separate dust particles from the flue gas. The dust is collected inside the dust collector, while the purified flue gas is discharged into the atmosphere. The venting device interface 21 is interlocked with the boiler body 1's pressure, temperature, and other parameter monitoring system. When the furnace pressure exceeds the set upper limit or other dangerous conditions occur (such as abnormal temperature rise), the interlock system is activated, the venting device interface 21 opens, and the gas inside the furnace is released to reduce the furnace pressure and ensure the safe operation of the boiler. The negative pressure detection pipe 17 monitors the furnace pressure in real time. When the furnace negative pressure deviates from the normal range, the combustion status inside the furnace can be adjusted by regulating the airflow of the secondary air duct 19 and other air intake devices to ensure stable furnace pressure and maintain normal combustion and heat generation. In case of fire or other emergencies, inert gas can be injected into the furnace through the inert gas extinguishing port 20 to suppress combustion and prevent the fire from spreading. At the same time, components such as the ash removal port 12 and ash removal door 23 facilitate ash removal operations inside the boiler during routine maintenance and in emergencies to ensure the normal operation of the boiler.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
