Example 1:

Referring to fig. 1-4 of the specification, the energy-saving environment-friendly water jacket heating furnace comprises a heating furnace body 1, wherein a pyrotechnic tube 10 for heating working medium water contained in the heating furnace body 1 is arranged in the heating furnace body 1, the pyrotechnic tube 10 is connected with a burner 2, the energy-saving furnace further comprises an energy-saving cylinder 5, a gas diffuser is arranged in the energy-saving cylinder 5, the gas diffuser comprises an S-shaped winding diffusion tube and radiating fins fixedly arranged on the diffusion tube, the outlet end of the diffusion tube is arranged in an opening manner and is arranged at a position close to the top of the energy-saving cylinder 5, the inlet end of the diffusion tube is communicated with a chimney 3 of the burner 2, and the top of the energy-saving cylinder 5 is provided with an exhaust pipe 18 communicated with the outside atmosphere; the heating furnace further comprises an oil gas inlet pipe 6 and an oil gas outlet pipe 7 which are used for the circulation of the heating object and penetrate through the heating furnace body 1 and the energy-saving cylinder 5 at the same time, and the ends of the oil gas inlet pipe 6 and the oil gas outlet pipe 7 in the heating furnace body 1 are mutually communicated.

Working principle:

The heating furnace body 1 is a main structural component of the whole water jacket heating furnace and is mainly used for containing water serving as a heating medium, the burner 2 ignites fuel and burns in the pyrotechnic tube 10, so that a large amount of heat is generated to heat the pyrotechnic tube 10, the water in the heating furnace body 1 is heated in a heat transfer mode, the temperature of the water is continuously increased and steam is generated, and the water exchanges heat with the oil gas inlet tube 6 and the oil gas outlet tube 7 which are positioned in the heating furnace body 1, so that the object medium needing to be heated, such as petroleum and the like, is heated, and the purpose of reducing the flow resistance and viscosity of petroleum is achieved. The above-mentioned process is not substantially different from the existing water jacket heating furnace, the improvement point of this embodiment is that the high-temperature gas exhausted from the chimney 3 of the burner 2 is reused, the high-temperature gas exhausted from the combustion is led into the gas diffuser installed in the energy-saving cylinder 5 through the chimney 3, the high-temperature gas flows through the gas diffuser, and the heat is transferred into the water in the energy-saving cylinder 5 through the gas diffuser, so as to exchange heat with the oil gas inlet pipe 6 and the oil gas outlet pipe 7 at the same time, the temperature of the oil gas inlet pipe 6 is obviously lower than the temperature in the energy-saving cylinder 5, and the preheating effect can be achieved; for the oil gas outlet pipe 7, the temperature is slightly lower than the temperature in the energy-saving cylinder 5, so that the effect of further heating or heat preservation can be achieved, the heat of the high-temperature air flow in the chimney 3 is fully utilized, the heat efficiency is improved, the same fuel is combusted, the temperature of the object medium can be heated to a higher temperature, and meanwhile, less heat and waste gas are discharged to the outside, so that the energy-saving and environment-friendly effects are achieved. It should be noted that, the high-temperature gas in the chimney 3 does not just exchange heat through the gas diffuser alone, and after the gas flow completely passes through the gas diffuser, the gas with temperature is discharged from the diffuser pipe into the energy-saving cylinder 5, and finally, the gas is naturally exchanged and then discharged into the atmosphere through the exhaust pipe 18, so that the heat discharged from the chimney 3 is fully utilized as much as possible.

Example 2:

On the basis of embodiment 1, further refining and improving the structure, as shown in fig. 1-4, in order to further dynamically adjust heat and enable more reasonable heat distribution, ensuring that the object medium to be heated can obtain better heat exchange, the device further comprises a circulation adjusting mechanism, wherein the circulation adjusting mechanism comprises a water outlet pipe 12, a first water pump 13 and a water pipe 15 which are communicated in sequence, the free end of the water outlet pipe 12 is communicated with the bottom of the heating furnace body 1, and the free end of the water pipe 15 is communicated with the bottom of the energy-saving cylinder 5; and the water supply pipe 17, the second water pump 19 and the water suction pipe 20 are mutually communicated, the free end of the water supply pipe 17 is communicated with the top of the heating furnace body 1, and the water suction pipe 20 is communicated with the energy-saving cylinder 5 and penetrates into a position close to the inner bottom of the energy-saving cylinder 5.

For more convenient, high-efficient, intelligent regulation/adjustment heat, in this embodiment, circulation adjustment mechanism still includes the controller, the controller respectively with first water pump 13 and second water pump 19 electricity are connected, still be provided with the liquid level sensor 8 that is used for detecting the water level and the temperature sensor 14 that is used for detecting the temperature on the inside wall of energy-conserving section of thick bamboo 5, liquid level sensor 8, temperature sensor 14 all with the controller electricity is connected.

Compared with the embodiment 1, the circulation adjusting mechanism is added, so that water in the heating furnace body 1 and the energy-saving cylinder 5 can be circulated, heat is utilized more scientifically, and the principle is as follows:

The controller collects information of the liquid level sensor 8 and the temperature sensor 14 in real time, when the liquid level in the energy-saving cylinder 5 collected by the liquid level sensor 8 is higher than a preset liquid level, in order to avoid overflow phenomenon caused by continuous rise of the liquid level due to high-temperature gas vaporization, at the moment, protective water transfer is triggered, and a driving electric signal is sent to the second water pump 19 through the controller, so that the second water pump 19 pumps water in the energy-saving cylinder 5 into the heating furnace body 1; when the liquid level sensor 8 does not acquire liquid level information, the second water pump 19 stops working, so that the liquid level in the energy-saving cylinder 5 is ensured to be always kept at the upper and lower positions of the liquid level sensor 8. When the temperature collected by the temperature sensor 14 is lower than the preset temperature, the controller triggers the first water pump 13 to work, and the high temperature water in the heating furnace body 1 is supplemented into the energy-saving cylinder 5, so that the problem that the temperature in the energy-saving cylinder 5 is too low due to insufficient high temperature airflow heating, and the purpose of heating or heat preservation of the oil-gas outlet pipe 7 cannot be achieved is avoided. The probability of occurrence of the situation is extremely low, because the general preinspection temperature is the actual temperature of the object medium, such as petroleum, in the oil gas outlet pipe 7, and the heat of the high-temperature steam airflow discharged by the chimney 3 is enough to heat the water in the energy-saving cylinder 5 to be higher than the water temperature in the heating furnace body 1 because the water quantity in the energy-saving cylinder 5 is small; however, in special cases, such as a sudden abnormal combustion deficiency of the burner 2, a flameout, a small fire, an intermittent air supply deficiency, etc., this may lead to an insufficient flue gas, so that the temperature in the energy saving cartridge 5 may gradually decrease, even below a preset temperature.

As an alternative preferred arrangement, the present embodiment also optimizes the following structure: in order to improve the heat exchange efficiency, the pyrotechnic tube 10 is preferably transversely arranged inside the heating furnace body 1, and one end of the pyrotechnic tube 10 close to the burner 2 is preferably a node tube 11.

Still further preferably, the oil gas inlet pipe 6 and the oil gas outlet pipe 7 are provided with fin pipes 9 at the portions of the heating furnace body 1 and the energy-saving cylinder 5. The arrangement of the corrugated tube 11 and the fin tube 9 is performed by utilizing the characteristic that the heat conduction performance of the metal solid is faster, so that the heat exchange efficiency is improved, and the temperature of the target medium can be increased as much as possible in the same temperature difference and heat exchange time.

Preferably, the inlet end of the diffusion pipe is communicated with the chimney 3 through a communication flow guiding pipe 16. The purpose of the flow guide tube 16 is to play a role in stabilizing and regulating pressure, in general, the inner diameter of the flow guide tube 16 should be obviously larger than that of the diffusion tube so as to solve the problems of uneven exhaust or overlarge resistance of the chimney 3, and the too small diameter of the flow guide tube 16 may cause uneven local pressure in the flow guide tube 16 due to overlarge airflow flow or speed of the chimney 3, so that the combustion of the combustor 2 is affected; to solve this problem, of course, the existing burner 2 already has a separate oxygen supply, which makes it possible to increase the pressure resistance from one end of the burner 2, so that the magnitude of the exhaust pressure does not generally affect the operation of the burner 2.

In this embodiment, two lifting frames 22 are connected to the bottom of the energy saving cylinder 5, and the first water pump 13 is connected to the inside of one of the lifting frames 22.

In this embodiment, the bottom of the heating furnace body 1 is connected with four support frames 23, and the top of the heating furnace body 1 is communicated with a liquid adding cylinder 4.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
