Description

Technical Field

[0001] The utility model belongs to the technical field of gasification devices, and in particular relates to a methanol gasification device. Background Art

[0002] Methanol has a very simple structure and is the simplest of the saturated monohydric alcohols. Its molecular weight is 32.04, its boiling point is 64.7°C, and its melting point is -97.8°C. Methanol is a colorless, transparent liquid with a similar odor to ethanol, but it is highly toxic and cannot be drunk.

[0003] Methanol can be used as a fuel. It has a high calorific value and can release a lot of energy when burned. It can replace some oil and natural gas. When methanol is burned, it needs to be atomized / gasified and mixed with air to become a combustible gas before it can be burned.

[0004] In the common methanol gasification devices currently available, methanol and air are not mixed sufficiently, which leads to poor combustion effect; and there is a lack of anti-flashback protection structure, which causes excessive pressure in the methanol gasification device when flashback occurs. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a methanol gasification device, which can ensure the full mixing of methanol and air and has an anti-flashback structure.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A methanol gasification device comprises a collecting hood and a perforated tube, wherein the lower end of the collecting hood is detachably connected to a bottom cover, and after the bottom cover is connected, a gasification chamber is formed inside the collecting hood; when the pressure inside the gasification chamber is too high, the bottom cover can be separated from the collecting hood;

[0008] The orifice tube is arranged in the collecting hood, and a plurality of through holes are distributed on the orifice tube. A nozzle is arranged on the top of the orifice tube, and the nozzle sprays methanol gas into the orifice tube; an air guide plate is fixedly connected to the outer wall of the orifice tube; an air inlet pipe and an air outlet pipe are connected on the collecting hood; external air enters the collecting hood through the air inlet pipe, and moves along the orifice tube under the action of the air guide plate to draw out the methanol gas in the orifice tube, and the external air is mixed with the methanol gas to obtain combustible gas, and the combustible gas is discharged through the air outlet pipe.

[0009] The bottom cover is plugged or clamped with the collecting cover, and a sealing gasket is provided at the connection.

[0013] It also includes an oil tank. The bottom cover is provided with an oil drain pipe connected to the oil tank. The methanol in the gasification chamber can flow into the oil tank through the oil drain pipe.

[0014] An oil pump is arranged in the oil tank, and the oil pump is connected with the nozzle through an oil delivery pipe.

[0015] A portion of the oil delivery pipe is located in the collecting cover, and the portion is a spiral pipe.

[0016] The oil drain pipe is a hose; the oil drain pipe is fixedly connected to the bottom cover.

[0017] The upper end of the oil drain pipe is fixedly connected to the bottom cover; the lower part of the oil drain pipe is slidably connected to the oil tank;

[0018] The bottom of the oil tank is detachably connected with an oil drain plug; the oil tank is provided with an oil inlet.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1-6 As shown, a methanol gasification device includes a collecting hood 1 and a perforated tube 2. The lower end of the collecting hood 1 is detachably connected to a bottom cover 4. After the bottom cover 4 is connected, a gasification chamber 3 is formed inside the collecting hood 1. Methanol gas and air are mixed into a combustible gas in the gasification chamber 3. The combustible gas is led to a burner for combustion. When other conditions such as backfire occur and cause the internal pressure of the gasification chamber 3 to be too high, the bottom cover 4 is separated from the collecting hood 1 under the action of the internal pressure, and the bottom cover 4 falls off, thereby preventing the occurrence of dangers such as internal overpressure and deflagration.

[0032] The orifice tube 2 is arranged in the collecting hood 1, and a plurality of through holes are distributed on the orifice tube 2. A nozzle 5 is arranged on the top of the orifice tube 2, and the nozzle 5 sprays methanol gas into the orifice tube 2. The methanol gas can collide with the inner wall of the orifice tube 2, 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 2. The collecting hood 1 is connected with an air inlet pipe 7 and an air outlet pipe 8; the external air enters the collecting hood 1 through the air inlet pipe 7, and the combustible gas is discharged through the air outlet pipe 8. Specifically: the air outlet pipe 8 is located at the upper part of the collecting hood 1, and the air inlet pipe 7 is located at the lower part of the collecting hood 1.

[0033] An air guide plate 6 is fixedly connected to the outer wall of the perforated tube 2. Under the action of the air guide plate 6, external air moves along the perforated tube 2 to lead out the methanol in the perforated tube 2, so that the external air and methanol are fully mixed to obtain combustible gas, which is finally discharged through the outlet pipe 8.

[0034] Furthermore, the bottom cover 4 and the collection cover 1 are connected by plugging, snapping or other detachable connection methods. In addition, a sealing gasket 9 is provided at the connection to ensure the seal under normal conditions. When the bottom cover 4 and the collection cover 1 are connected, the sealing gasket 9 will be squeezed to form a seal and generate resistance, thereby ensuring the connection between the bottom cover 4 and the collection cover 1 under normal conditions.

[0035] Furthermore, the above-mentioned orifice tube 2 is fixedly connected to the bottom cover 4 or the collection cover 1. When the orifice tube 2 is fixedly connected to the collection cover 1, the orifice tube 2 will not fall if the bottom cover 4 falls; however, there is a certain inconvenience in the disassembly and assembly of the orifice tube 2. If the orifice tube 2 is fixedly connected to the bottom cover 4, the bottom cover 4 falls, and the orifice tube 2 will fall with it; however, this connection method can facilitate the disassembly and assembly of the orifice tube 2. Therefore, the specific fixed position of the orifice tube 2 can be selected according to actual needs.

[0036] Furthermore, the air guide plate 6 is a spiral plate; external air can move in a spiral shape along the spiral plate to bring (lead out) the methanol gas from the perforated tube 2.

[0037] Furthermore, a heating device 10 is provided on the collecting hood 1. The heating device 10 can be a heating belt or a heating ring, and its purpose is to heat the inside of the collecting hood 1. At the start of operation or as needed, the methanol oil in the input nozzle 5 is heated to form methanol gas.

[0038] Furthermore, the part of methanol gas that is not fully vaporized falls to the bottom of the perforated tube 2 and enters the oil tank 11 through the oil drain pipe 12 on the bottom cover 4 to achieve its recovery.

[0039] Furthermore, an oil pump 13 is provided in the oil tank 11, and the oil pump 13 is connected to the nozzle 5 through the oil pipe 14; that is, the recovered methanol oil can be sprayed from the nozzle 5 through the oil pipe 14 into the orifice tube 2 to achieve circulation.

[0040] Furthermore, a portion of the oil pipeline 14 is located in the collecting cover 1, and the portion is a spiral tube 140; the structure of the spiral tube 140 can allow methanol to fully absorb the heat generated by the heating device 10, thereby ensuring that the methanol is fully heated.

[0041] Specifically: the oil delivery pipe 14 can pass through the base and extend into the collecting cover 1; for this purpose, the oil delivery pipe 14 located outside is a hose, which will not hinder the bottom cover 4 from falling. Alternatively, the oil delivery pipe 14 can pass through the side wall of the collecting cover 1 and extend into the collecting cover 1. Since it does not pass through the bottom cover 4, the oil delivery pipe 14 located outside does not need to be a hose. The oil delivery pipe 14 can be divided into three parts, the lower part is located in the oil tank 11, the middle part is located outside, and the upper part is located in the collecting cover 1; that is, the upper part is a spiral tube 140, and its end is connected to the nozzle 5.

[0042] Furthermore, the oil drain pipe 12 is a hose, which will not hinder the separation between the bottom cover 4 and the collecting cover 1. It can be connected to the bottom cover 4 in a fixed connection manner.

[0043] Furthermore, the upper end of the oil drain pipe 12 is fixedly connected to the bottom cover 4, and the lower part of the oil drain pipe 12 is slidably connected to the oil tank 11, and a corresponding sliding hole 110 is provided on the oil tank 11. In order to ensure sealing, a sealing ring is provided between the sliding hole 110 and the oil drain pipe 12. With this structural arrangement, when the bottom cover 4 is separated, the oil drain pipe 12 moves along the sliding hole 110 under the push of the internal pressure of the collecting cover 1. That is, the bottom cover 4 can be prevented from moving at will after falling.

[0044] Further, the bottom of the oil tank 11 is detachably connected with an oil drain plug 15, and a corresponding oil drain port is provided at the bottom of the oil tank 11, and impurities in the oil tank 11 can be discharged as needed. Specifically, a threaded connection can be adopted, and the oil drain plug 15 is used to block the oil drain port when impurities are not discharged.

[0045] Furthermore, the oil tank 11 is provided with an oil inlet 16 , and external oil can flow into the oil tank 11 through the oil inlet 16 to refuel the oil tank 11 .

[0046] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
