Description

Technical Field

[0001] This invention relates to the field of methanol power generation technology, and in particular to a methanol-heated methanol generator set. Background Technology

[0002] Methanol generator sets are internal combustion engine-driven power generation devices that use methanol (CH3OH) as fuel. The heat energy released by the combustion of methanol and air drives the crankshaft to rotate and generate electricity. They have high environmental protection and economic benefits. Moreover, because methanol is a renewable resource, it has a high energy density and can provide more energy to the generator set for the same volume or mass, ensuring that the generator set has good range and high power generation efficiency.

[0003] Current generator sets are prone to increased viscosity in low-temperature environments, making it difficult for methanol to be fully atomized. This results in larger, unevenly distributed droplets, affecting the normal operation of the generator.

[0004] Therefore, there is an urgent need to provide a methanol generator set that heats methanol fuel. Summary of the Invention

[0005] The purpose of this invention is to provide a methanol-heated methanol generator set, which aims to solve the problem that in the prior art, the viscosity of the generator set easily increases in low-temperature scenarios, making it difficult for methanol to be fully atomized, resulting in larger and unevenly distributed droplet particles that affect the normal operation of the generator.

[0006] To achieve the above objectives, the present invention provides a methanol-heated methanol generator set, comprising a generator body and a heating unit. The heating unit includes an oil pipeline, a connecting flange, a heating chamber, a heat-conducting layer, multiple heat-conducting columns, a heating wire, a temperature sensor, and a waste heat recovery assembly. The heating unit is connected to the generator body. The connecting flange is detachably connected to the generator body and is located at the input end of the generator body. The oil pipeline is fixedly connected to the connecting flange and is located on the inner side wall of the connecting flange. The heat-conducting layer is fixedly connected to the oil pipeline and is located on the outer side wall of the oil pipeline. The heating chamber is fixedly connected to the heat-conducting layer and is located on the outer side wall of the heat-conducting layer. The multiple heat-conducting columns are respectively fixedly connected to the heat-conducting layer and are located on the outer side wall of the heat-conducting layer. The oil pipeline has multiple embedding holes, each of which is adapted to a corresponding heat-conducting column. The temperature sensor is connected to the oil pipeline and is located on the inner side wall of the oil pipeline. The waste heat recovery assembly is connected to the generator body.

[0007] The heating unit further includes a base frame and a heat insulation layer. The base frame is detachably connected to the generator body and is located on the outer side wall of the generator body. The heat insulation layer is fixedly connected to the heating chamber and is located on the outer side wall of the heating chamber.

[0008] The heating unit further includes a formaldehyde tank, a delivery pump, and a connecting pipe. The formaldehyde tank is fixedly connected to the base frame and located above the base frame. The delivery pump is detachably connected to the base frame and located above the base frame, and the delivery pump is connected to the formaldehyde tank. The connecting pipe is connected to both the delivery pump and the oil pipeline.

[0009] The heating unit further includes a base column and an adjustment seat. The base column is fixedly connected to the base frame and located below the base frame. The adjustment seat is threadedly connected to the base column and located on the inner side wall of the base column.

[0010] The heating unit also includes an electrical cabinet, which is fixedly connected to the base frame and located above the base frame.

[0011] The waste heat recovery assembly includes a heat absorption chamber, a first conveying pipe, a second conveying pipe, a heat exchanger, and a circulating pump. The heat exchanger is detachably connected to the base frame and is located above the base frame. The heat absorption chamber is in contact with the generator body and is located below the generator body. The first conveying pipe is connected to both the heat exchanger and the heat absorption chamber. The circulating pump is connected to the heat exchanger and is located at the input end of the heat exchanger. The second conveying pipe is connected to both the circulating pump and the heat exchanger.

[0012] The waste heat recovery component includes a cooling fan, which is detachably connected to the heat exchanger and located below the heat exchanger.

[0013] This invention discloses a methanol-heated methanol generator set. During formaldehyde fuel refueling, the formaldehyde fuel is transported through a fuel delivery pipeline, which is installed with a connecting flange by detaching it from the input end of the generator body. During operation, a temperature sensor monitors the fuel temperature in real time. When the temperature is low, the heating wire is activated, and the generated heat is transferred to the inside of the fuel delivery pipeline through the heat-conducting layer and multiple embedded heat-conducting columns to heat the formaldehyde fuel. Simultaneously, the waste heat generated by the generator body is recovered and utilized through a waste heat recovery component, forming an efficient formaldehyde fuel heating process. This method avoids an increase in the viscosity of the formaldehyde fuel, ensuring that the methanol is fully atomized and that the generator body operates normally. Attached Figure Description

[0024] The heat-conducting layer 105 can use a graphene heat-conducting film, which has both high thermal conductivity and chemical corrosion resistance, and is suitable for formaldehyde fuel heating.

[0025] The heat-conducting pillar 106 is made of thermally conductive silicone, which can achieve the sealing of the embedding hole 125.

After being dissipated by the heat exchanger 120, the heat is applied to the oil pipeline 102, realizing heat recovery and utilization, and also reducing the workload of the heating wire 107.

[0036] Furthermore, the cooling fan 122 is detachably connected to the heat exchanger 120 and is located below the heat exchanger 120.
