Description

Technical Field

[0001] This utility model relates to an atmospheric pressure high-efficiency electrode boiler system, which falls within the field of heat energy utilization, heating, ventilation and air conditioning technology. Background Technology

[0002] Conventional high-pressure electrode boilers directly utilize a 10kV (or 6kV) three-phase high-voltage power supply to immerse the L1, L2, and L3 three-phase high-voltage electrodes in water with a certain conductivity. By utilizing the conductivity and high resistance of water, the boiler water is directly heated, turning it into high-temperature water above 90℃. Water is both a heat transfer medium and a heat-generating medium. High-temperature water can be stored through an external heat exchanger in a boiler or directly supplied to users, especially for heating or storing heat in larger electric boilers with a power rating of 0.5MW or higher. Compared to lower-voltage electric boilers, it saves on the investment in low-voltage transformers, which is its biggest advantage, although its efficiency is generally around 95%. The biggest advantage of high-carbon molecular heating oil is that synthetic oil at high temperatures has self-heating properties, increasing efficiency by about 150%-160% compared to traditional electric heating systems. Heating synthetic high-carbon molecular heating oil with a low-voltage 380V / 220V electric heater is convenient. Furthermore, if a high-pressure electrode boiler is used directly to provide steam, a pressurized high-pressure electrode boiler with water as the heating medium must be used, which is technically more complex, increases equipment costs exponentially, and places higher demands on safety. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a low-cost, stable, safe and energy-saving atmospheric pressure high-efficiency electrode boiler system.

[0004] To achieve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An atmospheric pressure high-efficiency electrode boiler system includes an electric heating tank, an electric heating electrode disposed on the electric heating tank, and an external heat exchange system connected to the electric heating tank.

[0006] The electric heating tank is filled with high-carbon molecular heating oil.

[0007] The electric heating tank is equipped with a reaction additive addition port;

[0008] The electric heating electrode is inserted into the high-carbon molecular heating oil.

[0009] Furthermore, the external heat exchange system includes a first circulating pump connected to the electric heating tank and a heat exchanger connected to the outlet of the first circulating pump.

[0010] The heat exchanger is connected to the load side;

[0011] The inlet of the first circulating pump is connected to the outlet of the electric heating tank;

[0012] The outlet of the first circulating pump is connected to the heat source side inlet of the heat exchanger;

[0013] The heat source side outlet of the heat exchanger is connected to the inlet of the electric heating tank.

[0014] Furthermore, the load-side inlet of the heat exchanger is connected to the second circulating pump via a pipeline, and the load-side outlet of the heat exchanger is connected to the heat-using equipment via a pipeline.

[0015] Furthermore, nano-sized conductive graphite powder is added to the high-carbon molecular heating oil.

[0016] Furthermore, the heat source side and the load side of the heat exchanger are subjected to counter-current forced heat exchange.

[0017] The beneficial effects of adopting the above technical solution are as follows:

[0018] Compared to conventional high-voltage electrode heating systems (devices that use electricity to convert water into high-temperature water), which involve inserting high-voltage electrodes into water or spraying water onto high-voltage electrodes to heat the water, this invention uses nano-scale graphite powder as a conductive medium instead of water. It utilizes electrodes suitable for low-voltage electricity (380V / 220V) to heat "high-carbon molecular heating oil." By leveraging the high-temperature self-heating characteristics of the "high-carbon molecular heating oil," the operating efficiency of the heating equipment is improved. Under different environmental conditions, the "high-carbon molecular heating oil" generates varying degrees of frictional heat and reactive heat (including chemical reduction, with the products then linked to other substances in a chain reaction). This process consumes substances that promote chemical reduction reactions. During unit operation, a portion of the electrical energy is used for similar driving energy consumption, thereby indirectly enabling the "high-carbon molecular heating oil" to generate excess self-generated heat. High-carbon molecular oil is a highly concentrated formula liquid mixture composed of various chemical elements, possessing the four characteristics of being non-toxic, odorless, non-corrosive, and radiation-free. It also features good thermal conductivity, rapid heating, and slow cooling. Under normal conditions, high-carbon molecular oil does not generate additional heat; only under different conditions such as electrode magnetic stimulation within a rated range and a closed inner ring do it undergo varying degrees of characteristic changes and generate its own heat. With multi-point activation of the heating electrodes, it rapidly heats up, reaching a maximum temperature of approximately 220℃ in a short time. The boiling point is 420℃, creating different curvilinear conditions for the heating of the liquid. It consumes very little electrical energy during the heating process, converting it into maximum heat energy, which is transferred to the heated water through high-strength alloy heat exchange tubes. This saves 50% more electricity than conventional electric heating, achieving highly efficient heating and ultimately producing high-quality hot water steam, widely used for heating and domestic hot water.

[0019] This invention requires the addition of a self-heating substance that undergoes a chemical reduction reaction. Based on calculations such as operating time and power, the substance is added to a high-carbon molecular heating oil, enabling the self-heating chemical reduction reaction to continue. The generation of this self-heating heat consumes only 1 unit of electrical energy for similar driving in actual equipment operation. Through self-heating physical and chemical reaction mechanisms, it can generate more than 1.6 units of heat energy, improving thermal efficiency and saving operating costs.

[0020] This invention employs a normal-pressure, high-temperature external heat exchange system, which operates at normal pressure and can produce high-temperature steam with high safety. The electrode is inserted into the solution of "high-carbon molecular heating oil" from the top of the normal-pressure boiler tank. The tank is under normal pressure, and the heat generated by the high-temperature "high-carbon molecular heating oil" is replaced by the external heat exchange system. It operates at high temperature and normal pressure with high safety and achieves high-pressure, high-temperature steam output of over 120°C.

[0021] The electrode boiler system adopted in this invention can achieve high-temperature steam supply under normal pressure, and can raise the maximum temperature to about 220°C in a short time. The heating of the "high carbon molecular heating oil" with a boiling point of 420°C is achieved. After heat exchange with the high-temperature high carbon molecular heating oil under normal pressure, it can easily provide high-temperature and high-pressure steam above 120°C. Compared with the pressurized high-pressure electrode boiler system, this technology is simpler, the equipment cost is reduced exponentially, and the safety is higher.

[0022] The high-carbon molecular heating oil of this invention contains a certain amount of nano-level conductive graphite powder, which increases its conductivity. When current passes through the electrolyte of nano-level conductive graphite powder integrated into the molecular oil, heat is generated. The electrode boiler utilizes this characteristic, using the uniformly suspended conductive nano-level conductive graphite powder as a heating resistor to complete the heating process of the electrode boiler.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] As attached Figure 1-2As shown, this embodiment provides an atmospheric pressure high-efficiency electrode boiler system, which includes an electric heating tank 1, an electric heating electrode 2 disposed on the electric heating tank 1, and an external heat exchange system 4 connected to the electric heating tank 1. The electric heating tank 1 is filled with high-carbon molecular heating oil 3, and the electric heating electrode 2 is inserted into the high-carbon molecular heating oil 3. An appropriate proportion of nano-level conductive graphite powder electrolyte is added to the high-carbon molecular heating oil. The suspended conductive nano-level conductive graphite powder acts as a heating resistor, completing the electrode boiler heating process. The addition of a certain amount of nano-level conductive graphite powder to the high-carbon molecular heating oil increases its conductivity. When current passes through the nano-level conductive graphite powder electrolyte integrated into the molecular oil, heat is generated. The electrode boiler utilizes this characteristic, using the uniformly suspended conductive nano-level conductive graphite powder as a heating resistor to complete the electrode boiler heating process. High-carbon molecular oil possesses self-heating properties, consuming minimal electrical energy while generating at least 1.6 times the efficiency. Its application in low-pressure high-carbon molecular oil electric heating boilers has been verified and widely adopted. This oil is a highly concentrated formula mixture of various chemical elements, possessing the four characteristics of being non-toxic, odorless, non-corrosive, and radiation-free. It also exhibits good thermal conductivity, rapid heating, and slow cooling. Under normal conditions, high-carbon molecular oil does not generate additional heat; only under different conditions, such as electrode magnetic stimulation within a rated range and a closed inner ring, does it undergo varying degrees of characteristic changes and generate its own heat. With multi-point activation of the heating electrodes, it rapidly heats up, reaching a maximum temperature of approximately 220℃ in a short time. The boiling point is 420℃, creating different curvilinear conditions for the heating of the liquid. During the heating process, it consumes very little electrical energy, converting it into maximum heat energy, which is transferred to the heated water through high-strength alloy heat exchange tubes. This results in 50% energy savings compared to conventional electric heating, achieving highly efficient heating and ultimately producing high-quality hot water steam, widely used for heating and domestic hot water. In heating applications in frigid regions, the actual energy efficiency is only about 10% lower than that of air source heat pumps, but the investment in heat source equipment is reduced by more than 60%. Compared to air source heat pumps, the payback period is shorter and the return on investment is higher in frigid regions. If used in the heating of large commercial complexes, coupled with technologies such as off-peak electricity storage, its advantages will be even more pronounced. Because high-carbon molecular heating oil can be heated to over 420℃ under normal pressure, and after heat exchange with water, it can directly produce high-temperature, high-pressure steam above 120℃, the technology is simpler, equipment costs are reduced exponentially, and safety is higher compared to pressurized high-pressure electrode boiler systems.

[0028] The electric heating tank 1 is equipped with a reaction additive inlet 5. The reaction additive is a chemical reduction reaction additive that releases heat during the reaction. The entire system uses electrodes to heat the "high-carbon molecular heating oil." Under different degrees of special high-temperature conditions, the "high-carbon molecular heating oil" generates different frictional heat and reaction heat (including chemical reduction, with the products then linked to other substances in a chain reaction). This consumes a certain amount of substances that promote the chemical reduction reaction. During unit operation, a portion of the electrical energy is used for similar driving costs, thereby indirectly achieving an excess of self-generated heat from the "high-carbon molecular heating oil." Engineering practice and third-party testing reports show that when the "high-carbon molecular heating oil" is heated to above 300°C, the generation of this self-generated heat only consumes 1 unit of electrical energy for similar driving in actual equipment operation. Through self-heating physical and chemical reaction mechanisms, at least 1.6 units of heat energy can be generated.

[0029] The external heat exchange system 4 includes a first circulation pump 401 connected to the electric heating tank 1 and a heat exchanger 403 connected to the outlet of the first circulation pump 401; the inlet of the first circulation pump 401 is connected to the outlet of the electric heating tank 1; the outlet of the first circulation pump 401 is connected to the heat source side inlet of the heat exchanger 403; the heat source side outlet of the heat exchanger 403 is connected to the inlet of the electric heating tank 1, that is, the outlet of the upper part of the electric heating tank 1 is connected to the first circulation pump 401, the heat source side inlet of the heat exchanger 403, and the heat source side outlet of the heat exchanger in sequence through a circulation pipe to the inlet of the lower part of the electric heating tank 1.

[0030] The heat exchanger 403 is connected to the load side; the load side inlet of the heat exchanger 403 is connected to the second circulating pump 402 through a pipeline, and the load side outlet of the heat exchanger 403 is connected to the heat-using equipment through a pipeline. The heat source side and the load side of the heat exchanger 403 are in counter-current forced heat exchange, which can provide hot water or steam to the load side for use by the heat-using equipment.

[0031] Heat exchange process description:

[0032] Heat exchange process on the heat source side: High-temperature liquid high-carbon molecular heating oil 3 is drawn out by the first circulation pump 401, enters the heat exchanger 403 through the circulation pipeline, and after releasing heat, the low-temperature high-carbon molecular heating oil 3 flows back to the lower half of the electric heating tank 1, completing the heat exchange process on the heat source side.

[0033] Load-side heat exchange process: Low-temperature water enters from the load-side inlet A of heat exchanger 403 via the second circulation pump 402. After counter-current heat exchange with heat exchanger 403, high-temperature hot water or steam is output from the load-side outlet B of heat exchanger 403 for use. The electrode boiler system adopted in this utility model can achieve high-temperature steam supply under normal pressure. The maximum temperature can be raised to about 220°C in a short time. The heating of "high-carbon molecular heating oil" with a boiling point of 420°C is achieved. After heat exchange with high-temperature high-carbon molecular heating oil under normal pressure, high-temperature and high-pressure steam above 120°C can be easily provided. Compared with the pressurized high-pressure electrode boiler system, this technology is simpler, the equipment cost is reduced exponentially, and the safety is higher.
