DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0038] like Figure 1-14 As shown, a heating and gas supply device comprises a combustion chamber 1, a smoke exhaust pipe 2, an air supply pipe 3, a water supply pipe 4 and a methanol gasification device 5. A combustion device 6 is arranged in the combustion chamber 1, and an air outlet pipe 58 of the methanol gasification device 5 is respectively connected with the combustion device 6 and the air supply pipe 3 through a three-way valve 7. Specifically, a fan can be arranged at the air outlet pipe 58 to extract the mixed combustible gas.

[0039] That is, the combustible gas generated by the methanol gasification device 5 can be supplied to other gas-using equipment, such as a gas stove, through the gas supply pipe 3; it can also provide combustible gas to the combustion device 6 in the device for heating cold water. Therefore, the device can not only provide hot water for heating, etc., but also supply gas to other gas-using equipment.

[0040] The smoke exhaust pipe 2 is connected to the combustion chamber 1, and the smoke exhaust pipe 2 has a smoke channel 20 and a water heating channel 21 which are not connected to each other; a heating water pipe 8 is arranged in the combustion chamber 1, and a jacket 100 is arranged on the combustion chamber 1, and the jacket 100 is connected to a water inlet pipe 101; the water inlet of the heating water pipe 8 is connected to the jacket 100 through a first pipe 9, and the water outlet of the heating water pipe 8 is connected to the water heating channel 21 through a second pipe 10; the water heating channel 21 is connected to the water supply pipe 4 through a third pipe 11; cold water passes through the jacket 100, the heating water pipe 8 and the water heating channel 21 in sequence through the water inlet pipe 101, is heated three times, and is then discharged from the water supply pipe 4.

[0041] Specifically: a variety of structures can be used to realize the flue gas channel 20 and the water heating channel 21. For example, a number of vertical pipes are arranged in the flue, and the upper and lower ends of the vertical pipes are connected to the smoke exhaust pipe 2 through orifice plates respectively; the vertical pipe is connected to the combustion chamber 1, that is, the inside of the vertical pipe is the flue gas channel 20, and a closed water heating channel 21 is formed between the outer wall of the vertical pipe, the inner wall of the smoke exhaust pipe 2 and the upper and lower orifice plates.

[0042] The combustion device 6 can use the methanol burner head 60 (burner head) in the prior art. The combustible gas discharged from the gas outlet pipe 58 is ignited by the ignition needle 61 at the burner head, and burns in the combustion chamber 1. The smoke is discharged through the smoke exhaust pipe 2. Specifically: the smoke exhaust pipe 2 has a smoke channel 20 and a water heating channel 21 that are not connected to each other; the smoke is discharged through the smoke channel 20, and an exhaust fan can be connected to the top of the smoke pipe to extract the smoke. The three-way valve 7 is connected to the burner head 60 in the combustion device 6 through the gas pipe 62.

[0043] A heating water pipe 8 is provided in the combustion chamber 1, and a jacket 100 is provided on the combustion chamber 1, and the jacket 100 is connected to a water inlet pipe 101; the water inlet of the heating water pipe 8 is connected to the jacket 100 through a first pipe 9, and the water outlet of the heating water pipe 8 is connected to a water heating channel 21 through a second pipe 10; the water heating channel 21 is connected to the water supply pipe 4 through a third pipe 11; cold water passes through the jacket 100, the heating water pipe 8, and the water heating channel 21 in sequence through the water inlet pipe 101, is heated three times, and then is discharged from the water supply pipe 4.

[0044] That is, water absorbs the heat discharged from the combustion chamber 1 through the jacket 100, then absorbs the heat inside the combustion chamber 1 through the water heating pipe, and finally absorbs the heat of the flue gas through the water heating channel 21. Therefore, through the above flow path, the heat generated during the combustion process can be fully absorbed to avoid heat waste.

[0045] Furthermore, the above-mentioned heating water pipe 8 is preferably a spiral coil.

[0046] Furthermore, the combustion chamber 1 is provided with an air distribution hole 12 and a drain pipe 14 connected thereto, and the air distribution hole 12 and the drain pipe 14 are not connected to the jacket 100. During combustion, combustion air distribution can be performed through the air distribution hole 12. The purpose of setting the drain pipe 14 is to discharge water generated after the combustion of methanol as needed.

[0047] Furthermore, the methanol gasification device 5 includes a collecting hood 50, an oil tank 51 and a perforated tube 52; a bottom cover 53 is connected to the lower end of the collecting hood 50, and after the bottom cover 53 is connected, a gasification chamber 54 is formed inside the collecting hood 50;

[0048] The orifice tube 52 is arranged in the collecting hood 50, and a plurality of through holes are distributed on the orifice tube 52. A nozzle 55 is arranged on the top of the orifice tube 52, and the nozzle 55 sprays methanol gas into the orifice tube 52. The methanol gas can collide with the inner wall of the orifice tube 52, and the part that is not fully vaporized is screened out; that is, the fully vaporized methanol gas is discharged through the through holes, and the part that is not fully vaporized falls to the bottom of the orifice tube 52. The collecting hood 50 is connected with an air inlet pipe 57 and an air outlet pipe 58; the external air enters the collecting hood 50 through the air inlet pipe 57, and the combustible gas is discharged through the air outlet pipe 58. Specifically: the air outlet pipe 58 is located at the upper part of the collecting hood 50, and the air inlet pipe 57 is located at the lower part of the collecting hood 50.

[0049] An air guide plate 56 is fixedly connected to the outer wall of the orifice tube 52. Under the action of the air guide plate 56, external air moves along the orifice tube 52 to draw out the methanol in the orifice tube 52, so that the external air and methanol are fully mixed to obtain combustible gas, which is finally discharged through the outlet pipe 58.

[0050] The bottom cover 53 is provided with an oil drain pipe 59 connected to the oil tank 51; the methanol in the gasification chamber 54 can flow into the oil tank 51 through the oil drain pipe 59. That is, the part of the methanol gas that is not fully gasified falls to the bottom of the hole tube 52 and enters the oil tank 51 through the oil drain pipe 59 on the bottom cover 53, so as to be recovered.

[0051] Furthermore, the bottom cover 53 is detachably connected to the collecting cover 50. When the internal pressure of the collecting cover 50 is too high, the bottom cover 53 can be separated from the collecting cover 50. When the internal pressure of the gasification chamber 54 is too high due to other conditions such as backfire, the bottom cover 53 is separated from the collecting cover 50 under the action of the internal pressure, and the bottom cover 53 falls, thereby preventing the occurrence of dangers such as internal overpressure explosion. The above-mentioned oil drain pipe 59 is a hose, which will not hinder the separation between the bottom cover 53 and the collecting cover 50. It can be connected to the bottom cover 53 in a fixed connection manner.

[0052] Furthermore, the bottom cover 53 and the collection cover 50 are connected by plugging, snapping or other detachable connection methods. In addition, a sealing gasket 510 is provided at the connection to ensure the seal under normal conditions. When the bottom cover 53 and the collection cover 50 are connected, the sealing gasket 510 will be squeezed to form a seal and generate resistance, thereby ensuring the connection between the bottom cover 53 and the collection cover 50 under normal conditions.

[0053] Furthermore, an oil pump 511 is provided in the oil tank 51, and the oil pump 511 is connected to the nozzle 55 through the oil delivery pipe 512; that is, the recovered methanol oil can be sprayed out from the nozzle 55 through the oil delivery pipe 512 into the hole pipe 52 to achieve circulation. Specifically: the oil tank 51 is connected to the filling pipe 516, and the methanol oil can be added to the oil tank 51 through the filling pipe 516.

[0054] Specifically: the oil delivery pipe 512 includes an inner pipe 513, a preheating pipe 514 and a spiral pipe 515 which are connected in sequence; the oil pump 511 is connected to the inner pipe 513, the preheating pipe 514 is located at the combustion chamber 1 (absorbing heat to heat the methanol oil), and the spiral pipe 515 is located in the collecting hood 50; the nozzle 55 is connected to the spiral pipe 515. A heating device 517 is provided on the collecting hood 50. The heating device 517 can be a heating belt or a heating ring, and its purpose is to heat the inside of the collecting hood 50. At the start of operation or as needed, the methanol oil in the input nozzle 55 is heated to form methanol gas.

[0055] When the combustion device 6 ignites the combustible gas, the preheating tube 514 can absorb the heat generated in the combustion chamber 1 to raise the temperature of the methanol, and further heat it up and gasify it through the heating device 517 (the spiral tube 515 absorbs the heat). When the heat generated in the combustion chamber 1 is sufficient for the methanol to gasify, the heating device 517 can be turned off.

[0056] Furthermore, it also includes a windshield 15, which is arranged on the combustion chamber 1; the windshield 15 is connected to the air intake pipe 57 through the air intake fan 16. That is, the introduced external air is hot air, which can further fully gasify the methanol.

[0057] Furthermore, in order to improve the integration, a shell 13 is also included, and the combustion chamber 1 and the methanol gasification device 5 are both fixed in the shell 13 .

[0058] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
