Description

Technical Field

[0001] The present invention relates to the field of methanol combustion, and particularly to a methanol combustion vaporizer. Background Art

[0002] A methanol combustion vaporizer is a device that converts liquid methanol into gas and mixes it with air for combustion, and is widely used in industrial heating, energy supply, alternative fuels and other fields. Among them, the conversion of liquid methanol into gas is usually achieved by using the waste heat generated by combustion or an external heat source (such as electric heating). Usually, the flame size is increased or decreased by increasing or decreasing the methanol flow rate. This method has some deficiencies. For example, no matter what kind of burner is used, the stability of the flame during combustion needs to be considered when in use, that is, the flame should not produce excessive fluctuations during continuous combustion to avoid affecting the use. However, since the methanol combustion vaporizer has a step of converting liquid methanol into gas, after changing the methanol flow rate, on the one hand, the amount of methanol flowing into the vaporization chamber becomes more or less, resulting in a change in the thickness of methanol in the vaporization chamber. On the other hand, in an area with a constant area, when pouring liquid, if the thickness of the liquid is different, the heat exchange contact area is different, resulting in different evaporation rates of the liquid, and the evaporation rate of the liquid and the thickness of the liquid are in a non-linear inverse relationship, not a linear change. That is to say, when adjusting the flame size by changing the methanol flow rate, the stability of the flame during combustion is relatively poor, and the adjustment accuracy is also relatively poor, which needs to be improved.

[0003] Based on the above, the present invention proposes a methanol combustion vaporizer. Summary of the Invention

[0009] As a further improvement and optimization of the present invention, the horizontal cross-section of the heat-conducting shaft is a regular polygon with the same number of sides as the number of sides of the vaporization area. And during the process of the decreasing area of the vaporization area, the side wall of the vaporization area can fit against the corresponding side wall of the heat-conducting shaft and block the liquid outlet fine holes provided on the heat-conducting shaft.

[0010] As a further improvement and optimization of the present invention, a liquid outlet fine hole is provided on each side surface of the heat-conducting shaft.

[0011] As a further improvement and optimization of the present invention, a lug extends from the outer circumferential surface of the rotating ring, the lug extends out of the vaporization chamber, and an avoidance opening for avoiding the lug is provided on the vaporization chamber. The vaporization assembly further includes a driving member for driving the lug to rotate around the axis of the rotating ring.

[0012] As a further improvement and optimization of the present invention, the driving member includes a rotating shaft coaxial with the rotating ring, a motor power-connected to the rotating shaft through a worm and worm gear, and a bracket for connecting the rotating shaft and the lug.

[0013] As a further improvement and optimization of the present invention, a combustion chamber is coaxially provided on the upper surface of the ring cover. An air inlet pipe is provided on the outer circumferential surface of the combustion chamber, a blower is provided at the end of the air inlet pipe, and a partition pipe extends coaxially upward from the inner circumferential surface of the ring cover. The upper end of the partition pipe is close to the combustion assembly.

[0014] As a further improvement and optimization of the present invention, the combustion assembly includes a burner head. A connecting groove is provided at the bottom of the burner head. The upper end of the heat-conducting shaft is arranged in the connecting groove. An outer ring groove and an inner ring groove are provided on the upper surface of the burner head. A connecting hole communicating with the connecting groove is provided on the groove wall of the inner ring groove. The inner ring groove and the outer ring groove are communicated through a side hole;

[0015] An igniter for igniting the methanol in the outer ring groove is provided in the combustion chamber.

[0016] As a further improvement and optimization of the present invention, an outer float is arranged in the outer ring groove, an inner float is arranged in the inner ring groove, and the outer float and the inner float are connected by a connecting rod, and the connecting rod passes through the side hole.

[0017] As a further improvement and optimization of the present invention, the supply component is located below the vaporization combustion component;

[0018] The supply component includes a transfer chamber, an input hole is arranged at the bottom of the transfer chamber, a valve I is arranged at the lower orifice of the input hole, and a water pump is arranged at the input end of the valve I;

[0019] A fixed core shaft is coaxially arranged at the bottom of the cavity of the transfer chamber. The upper end of the fixed core shaft extends out of the transfer chamber and is connected to a connecting pipe, and a valve II is arranged at the connection. The fixed core shaft is of a hollow shaft structure, a liquid inlet hole is arranged at the bottom of the fixed core shaft, a piston is sleeved in the transfer chamber, an avoidance hole for avoiding the fixed core shaft is arranged on the piston, a counterweight block is embedded in the piston, and the valve II adopts flow valve technology.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] When this solution is put into use, liquid methanol enters the heat conduction shaft through the connecting pipe and then flows into the vaporization area through the liquid outlet fine holes. Since the width of the liquid outlet fine holes is relatively small, the liquid methanol is distributed in the vaporization area and has a relatively thin thickness. Therefore, the liquid methanol can be quickly vaporized and continuously supplied to the burner head to ensure the stability of the flame combustion. On this basis, when it is necessary to adjust the flame size, the valve II is adjusted to adjust the liquid methanol flow rate. At the same time, the area of the vaporization area is adjusted according to the liquid methanol flow rate, so that the liquid methanol in the vaporization area always maintains a relatively thin thickness. That is to say, the thickness of the liquid methanol in the vaporization area remains unchanged, so the time spent on vaporizing the liquid methanol per unit area is basically the same, that is, the vaporization efficiency of the liquid methanol remains unchanged. Also, since the area of the vaporization area matches the adjusted liquid methanol flow rate, the gaseous methanol supplied to the burner head is consistent with the set value and the supply is relatively stable. To sum up, when adjusting the flame size by changing the methanol flow rate in this solution, the stability of the flame combustion is relatively better and the adjustment accuracy is also more precise.

Specific embodiments

[0035] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows.

[0036] Referring to Figures 1 - 11 , a methanol combustion vaporizer includes a supply member 100, a vaporization combustion member 200, and a connecting pipe 300 for connecting the two.

[0037] I. Supply component 100:

[0038] Referring to Figure 2 , the supply component 100 includes a transfer chamber 101. An input hole 102 is provided at the bottom of the transfer chamber 101. A first valve 103 is provided at the lower orifice of the input hole 102. The input end of the first valve 103 is provided with a water pump (not shown in the figure). The liquid methanol can be sent into the transfer chamber 101 by using the water pump.

[0039] A fixed core shaft 104 is coaxially arranged at the bottom of the cavity of the transfer chamber 101. The upper end of the fixed core shaft 104 extends out of the transfer chamber 101 and is connected to a connecting pipe 300, and a second valve 1042 is provided at the connection. The fixed core shaft 104 is of a hollow shaft structure. A liquid inlet hole 1041 is provided at the bottom of the fixed core shaft 104. The liquid inlet hole 1041 is used to realize the connection between the fixed core shaft 104 and the transfer chamber 101.

[0040] A piston 105 is sleeved in the transfer chamber 101. An avoidance hole for avoiding the fixed core shaft 104 is provided on the piston 105. A counterweight is embedded in the piston 105.

[0041] The first valve 103 adopts the existing solenoid valve technology, and the second valve 1042 adopts the existing flow valve technology.

[0042] When the first valve 103 is opened and the second valve 1042 is closed, the liquid methanol is sent into the transfer chamber 101 by the water pump. At the same time, the piston 105 will be lifted up by the liquid methanol. When the piston 105 moves up to the highest point, the transfer chamber 101 is filled with liquid methanol, and then the first valve 103 is closed. After that, when the second valve 1042 is opened, under the action of gravity, the piston 105 moves down and pushes the liquid methanol into the connecting pipe 300. It should be noted that the second valve 1042 adopts the existing flow valve technology. Therefore, by adjusting the second valve 1042, the flow rate of the liquid methanol sent into the connecting pipe 300 can be changed. In addition, the power source for driving the flow of the liquid methanol comes from the gravity of the piston 105, and the gravity of the piston 105 is a fixed value. Therefore, the flow rate of the liquid methanol during flow is relatively stable and the fluctuation is very small.

[0043] II. Vaporization combustion component 200:

[0044] Referring to Figures 3 - 11 , the vaporization combustion component 200 is located above the supply component 100.

[0045] The vaporization combustion component 200 includes a vaporization assembly 206.

[0046] Referring to Figures 5 - 9 , the vaporization assembly 206 includes a vaporization chamber 2061. The lower end of the vaporization chamber 2061 is closed and provided with an installation hole, and the upper end is open and provided with an annular cover 2062.

[0047] A heat conducting plate 2091 is fixed inside the mounting hole. A fixing hole coaxial with the vaporization chamber 2061 is provided on the heat conducting plate 2091. A heat conducting shaft 209 is coaxially arranged inside the fixing hole. The heat conducting shaft 209 is in the shape of a hollow shaft. The upper end of the heat conducting shaft 209 extends out of the vaporization assembly 206 and is provided with a combustion assembly 208. The lower end of the heat conducting shaft 209 extends out of the vaporization assembly 206 and is connected to a connecting pipe 300. Liquid outlet fine holes 2092 are arranged on the outer surface of the heat conducting shaft 209. The lower hole wall of the liquid outlet fine holes 2092 is flush with the upper surface of the heat conducting plate 2091.

[0048] A rotating ring 2065 is coaxially and rotatably mounted inside the vaporization chamber 2061. The upper surface of the rotating ring 2065 is in contact with the lower surface of the ring cover 2062. Lugs 2064 extend from the outer circular surface of the rotating ring 2065. The lugs 2064 extend out of the vaporization chamber 2061. An avoidance opening 2063 for avoiding the lugs 2064 is provided on the vaporization chamber 2061. By driving the lugs 2064 by a driving member, the rotating ring 2065 can be rotated. Further, the driving member includes a rotating shaft 204 coaxial with the rotating ring 2065, a motor 203 which is power-connected to the rotating shaft 204 through a worm and worm gear, and a bracket 205 for connecting the rotating shaft 204 and the lugs 2064. Therefore, the rotating ring 2065 can be driven to rotate by the motor 203.

[0049] A sliding plate 2068 is further arranged inside the vaporization chamber 2061. The upper surface of the sliding plate 2068 is in contact with the lower surface of the rotating ring 2065. The lower surface of the sliding plate 2068 is in contact with the bottom of the cavity of the vaporization chamber 2061. A plurality of sliding plates 2068 are arranged in an array along the circumferential direction of the rotating ring 2065. The opposite sides of the plurality of sliding plates 2068 form a vaporization area in the shape of a regular polygon.

[0050] Upper linkage holes 2066 are provided on the rotating ring 2065. Lower linkage holes 2067 are provided at the lower closed end of the vaporization chamber 2061. A convex pin 2069 arranged vertically is provided on the sliding plate 2068. The upper end of the convex pin 2069 is slidably connected to the upper linkage holes 2066. The lower end of the convex pin 2069 is slidably connected to the lower linkage holes 2067. And when the rotating ring 2065 rotates, through the cooperation of the convex pin 2069, the upper linkage holes 2066 and the lower linkage holes 2067, the sliding plate 2068 can be moved and the vaporization area remains in the shape of a regular polygon while the side length changes, so that the area of the vaporization area changes. Based on the area calculation formula of a regular polygon, it can be known that the area of a regular polygon is linearly proportional to the side length, that is: if the side length a of a regular polygon expands or shrinks by k times, then the new side length is ka, and the area of the new regular polygon is equal to k*k*A, where A is the area of the regular polygon with side length a. Thus, it can be known that the change in the area of the vaporization area can be calculated and will not be elaborated here.

[0051] In addition, the horizontal cross-section of the heat conduction shaft 209 is a regular polygon with the same number of side lengths as that of the vaporization zone. During the process of the decreasing area of the vaporization zone, the side wall of the vaporization zone can fit with the corresponding side wall of the heat conduction shaft 209 and block the liquid outlet micropores 2092 provided on the heat conduction shaft 209. Preferably, one liquid outlet micropore 2092 is provided on each side surface of the heat conduction shaft 209; when the liquid outlet micropore 2092 is blocked, after the liquid methanol enters the heat conduction shaft 209 through the connecting pipe 300, it continues to flow in the heat conduction shaft 209 and flows into the combustion assembly 208. When the liquid outlet micropore 2092 is opened, after the liquid methanol enters the heat conduction shaft 209 through the connecting pipe 300, it flows into the vaporization zone through the liquid outlet micropore 2092. Since the width of the liquid outlet micropore 2092 is small, the liquid methanol is distributed in the vaporization zone and has a relatively thin thickness. In addition, according to the required flame size, the valve two 1042 is adjusted to adjust the methanol flow rate. At the same time, according to the methanol flow rate, the area of the vaporization zone is adjusted to keep the liquid methanol always having a relatively thin thickness in the vaporization zone. The heat of the combustion assembly 208 is conducted to the liquid methanol through the heat conduction shaft 209 and the heat conduction plate 2091 made of heat-conducting materials to vaporize it.

[0052] Refer to Figure 3 And Figure 4 , a combustion chamber 207 is coaxially provided on the upper surface of the annular cover 2062. An air inlet pipe 202 is provided on the outer circumferential surface of the combustion chamber 207. A blower 201 is provided at the end of the air inlet pipe 202. An inner annular surface of the annular cover 2062 coaxially extends upward with a partition pipe 2071, and the upper end of the partition pipe 2071 is close to the combustion assembly 208; the blower 201 draws air into the combustion chamber 207 to provide combustion-supporting air for combustion. The vaporized gaseous methanol in the vaporization zone flows upward along the partition pipe 2071 to the vicinity of the combustion assembly 208 to supplement fuel for combustion.

[0053] Furthermore, in this solution, the liquid methanol is vaporized by the heat generated by combustion. Therefore, after the flame goes out, without heat, the liquid methanol cannot be vaporized normally. For this reason, refer to Figure 10 And Figure 11 , the combustion assembly 208 is improved.

[0054] The combustion component 208 includes a burner head 2081. A connecting groove 2082 is provided at the bottom of the burner head 2081. The upper end of the heat conduction shaft 209 is arranged in the connecting groove 2082. An outer ring groove and an inner ring groove 2083 are provided on the upper surface of the burner head 2081. A connecting hole 2084 communicating with the connecting groove 2082 is provided on the groove wall of the inner ring groove 2083. The inner ring groove 2083 and the outer ring groove are communicated through a side hole 2085. At the beginning, the area of the vaporization zone is the smallest, the liquid outlet fine hole 2092 is blocked, and liquid methanol flows into the outer ring groove through the heat conduction shaft 209, the connecting groove 2082, the connecting hole 2084, the inner ring groove 2083, and the side hole 2085. Then, the liquid methanol in the burner head 2081 is ignited by an igniter arranged in the combustion chamber 207, and a flame can be ignited. After a preset time, the area of the vaporization zone becomes larger, the liquid outlet fine hole 2092 is opened, and the liquid methanol in the heat conduction shaft 209 will flow to the vaporization zone through the liquid outlet fine hole 2092. Therefore, after waiting for a period of time, after the flame burns stably, it can be put into use.

[0055] Further, an outer float 2086 is arranged in the outer ring groove, and an inner float 2087 is arranged in the inner ring groove 2083. The outer float 2086 and the inner float 2087 are connected through a connecting rod 2088. The connecting rod 2088 passes through the side hole 2085. After the liquid methanol flows into the outer ring groove, the outer float 2086 will float up and drive the inner float 2087 to float together, thereby blocking the connecting hole 2084, and the liquid methanol will not flow into the burner head 2081. At the same time, for the flame gas, the heat conduction plate 2091 becomes hot, the area of the vaporization zone is adjusted to a set value, and the liquid methanol starts to flow into the vaporization zone and vaporizes.

[0056] The working process of the vaporization combustion component 200:

[0057] At the beginning, the area of the vaporization zone is the smallest, the liquid outlet fine hole 2092 is blocked, and liquid methanol flows into the outer ring groove through the heat conduction shaft 209, the connecting groove 2082, the connecting hole 2084, the inner ring groove 2083, and the side hole 2085. The outer float 2086 will float up and drive the inner float 2087 to float together, so as to block the connecting hole 2084 after the liquid methanol in the outer ring groove reaches a set amount. Then, the liquid methanol in the burner head 2081 is ignited by an igniter arranged in the combustion chamber 207, and a flame can be ignited.

[0058] Then, the area of the vaporization zone becomes larger until it reaches the set value, the liquid outlet fine hole 2092 is opened, and the liquid methanol in the heat conduction shaft 209 and the liquid methanol provided by the supply component 100 will flow to the vaporization zone through the liquid outlet fine hole 2092, vaporize and participate in combustion. After waiting for a period of time, after the flame burns stably, it can be put into use.

[0059] When this solution is put into use, liquid methanol enters the heat-conducting shaft through the connecting pipe and then flows into the vaporization zone through the liquid outlet fine holes. Since the width of the liquid outlet fine holes is relatively small, the liquid methanol is distributed in the vaporization zone with a relatively thin thickness. Therefore, the liquid methanol can be quickly vaporized and continuously supplied to the burner head to ensure the stability of the flame combustion. On this basis, when the flame size needs to be adjusted, valve two is adjusted to adjust the flow rate of the liquid methanol. At the same time, the area of the vaporization zone is adjusted according to the flow rate of the liquid methanol, so that the liquid methanol in the vaporization zone always maintains a relatively thin thickness. That is to say, the thickness of the liquid methanol in the vaporization zone remains unchanged. Therefore, the time spent on vaporizing the liquid methanol per unit area is basically the same, that is, the vaporization efficiency of the liquid methanol remains unchanged. Also, since the area of the vaporization zone matches the adjusted flow rate of the liquid methanol, the gaseous methanol supplied to the burner head is consistent with the set value and the supply is relatively stable. In summary, when adjusting the flame size by changing the methanol flow rate in this solution, the stability of the flame combustion is relatively good and the adjustment accuracy is more precise.
