Description

LPG Evaporation Construction

The present invention relates to a liquefied petroleum gas vaporization device for supplying the vaporized gas by converting the fuel into a vaporized state to a vaporized state in an industrial facility, a restaurant, etc. using liquefied petroleum gas as fuel, in particular a vaporization device A shut-off valve is installed in the inner cylinder at the bottom of the float to completely block the inflow of the liquefied petroleum gas from the liquefied petroleum gas storage tank in the event of malfunction or stoppage of the vaporization system, and at the same time, In the liquefied petroleum gas vaporizer for consuming liquefied petroleum gas remaining in the inner cylinder without exhausting the liquefied petroleum gas remaining in the inner cylinder to the atmosphere by supplying the vaporized gas storage tank or the place of use in the vaporized state It is about.

In general, liquefied petroleum gas has a property of vaporizing when the pressure is reduced when used as a gas liquefied by applying pressure at room temperature. Such liquefied petroleum gas is stored in a storage tank in a compressed state in a large kitchen, a business restaurant or an industrial site, and is completely vaporized through a vaporizer through a fuel supply pipe, and then supplied to a combustion means as needed. It is known that it is used as energy.

As described above, the vaporization device for converting the liquefied petroleum gas into the vaporized state is installed between the pipe associated with the liquefied petroleum gas storage tank (not shown) and the pipe associated with the combustion means (not shown), the outer cylinder The heater 10 is divided into the sieve 10 and the inner cylinder 20 which has a suitable diameter inside, and the heater 11 for heating the liquid (for example, water) filled in the outer cylinder 10 is installed.

The upper end of the inner cylinder 20 is protruded to the upper portion of the outer cylinder 10 is equipped with a mechanical element such as various valves required.

The float 21 is installed in the inner cylinder 20 of the vaporization device of the liquefied petroleum gas provided in this way, the outlet hole 22 for the gas of the gas evaporated state is formed to the upper end side of the inner cylinder 20 is formed The opening and closing port 23 provided at the upper end of the float 21 is in contact with the outflow hole 22 to allow a short-circuit connection to the pipe from which gas in a vaporized state is discharged from the inner cylinder 20. An inflow pipe 30 flowing from the petroleum gas storage tank is wound around the inner cylinder 20 and connected to the lower side of the inner cylinder 20.

On the other hand, the reason for having the float 21 and the opening and closing port 23 to the upper portion as described above is that the liquid liquefied petroleum gas is introduced along the inlet pipe 30 and then heated and wound by the heating of the heater 11 and the inner cylinder When the gas is introduced into the liquid, the petroleum gas in the liquid phase is vaporized and flows out of the vaporization apparatus. When the liquid petroleum gas becomes inoperable due to various reasons such as the malfunction of the heater 11, the liquid inside the outer cylinder 10 ( Water) The water temperature is lowered and the phenomenon that the petroleum gas of the liquid wound along the inlet pipe 30 is introduced into the inner cylinder 20 without being properly vaporized.

If this phenomenon continues for a certain time, the float 21, which is buoyant by the liquid petroleum gas level, rises, and thus the opening and closing port 23 connected to the upper portion of the float 21 is the inner cylinder 20. ) To prevent the outflow hole 22 penetrating to the top to prevent the outflow of liquid petroleum gas to the outside in advance, and to prevent the safety accident that may occur therefrom.

However, in such a case, a certain amount of liquefied petroleum gas is sufficiently introduced into the inner cylinder 20 more than necessary to raise the float 21 by buoyancy so that the opening and closing opening 23 on the upper portion of the float 21 opens the outlet hole 22. ), There is a problem that the amount of liquefied petroleum gas introduced is considerable, and in order to process the liquefied petroleum gas introduced in this way, it is generally naturalized and released into the atmosphere, so a large amount of liquefied petroleum gas It has been pointed out that energy sources are inefficiently managed and used, such as wasted by natural emission.

Therefore, the present invention has been made to solve the above problems, even if the liquid petroleum gas is introduced into the inner cylinder by the vaporization device malfunction of liquefied petroleum gas to minimize the inflow of the liquid petroleum gas introduced The main purpose is to minimize the waste of liquefied petroleum gas by allowing the gas to flow by the natural vaporization pressure to the combustion means side pipe again without being discharged by the atmospheric natural vaporization.

It is characterized by the configuration that the blocking plate 133 is provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a schematic separation perspective view of the present invention, Figure 2 is a front sectional view of the present invention, Figure 3 is an enlarged cross-sectional view of the main body of the present invention, Figure 4 is a perspective view of the shut-off valve of the present invention.

As shown in the accompanying drawings, the present invention relates to a liquefied petroleum gas storage tank associated with a vaporized device 100 for converting into a gas state associated with a pipe 200 from a separate liquefied petroleum gas storage tank (not shown) It is associated with and consists of an outer cylinder 110 of the vaporization device 100 and the inner cylinder 120 which is built in the interior and the shut-off valve 130 formed on the inner bottom of the inner cylinder 120.

Since the outer cylinder 110 is the same as a conventional conventional configuration and is not related to the scope of rights in the present invention, briefly describing the configuration, a plurality of mechanical elements such as various valves and gauges are formed above the outer cylinder 110. Then, the liquid (water) is filled into the outer cylinder 110, the heater 160 for heating the water at the lower end is installed.

Meanwhile, the inflow pipe 150 associated with the liquefied petroleum gas storage tank (not shown) penetrates through the upper portion of the outer cylinder 110 and has a configuration in which the inner cylinder 120 to be described later is wound several times. It has a structure which communicates with the cylinder 120 below.

The inner cylinder 120 is fixedly installed in the outer cylinder 110 and the inlet pipe 150 introduced through the outer cylinder 110 is wound around the circumference several times so that its end portion is the lower end of the inner cylinder 120. It is connected to the side.

As shown in FIG. 3, the inner cylinder 120 has a flange 140 crossing the lower side of the inner portion thereof, and a shutoff valve 130 for blocking liquefied petroleum gas at the central portion of the flange 140. Is fixedly installed.

Meanwhile, the float 121 is fixed to the upper end of the fixing rod 123 penetrating the shutoff valve 130 by a bolt 124, and fixedly coupled to the blocking plate 133 described later to the lower end of the fixing rod 123. do.

Such a float 121 is the same as the conventional configuration and function, that is, when the liquid liquefied petroleum gas flows into the inner cylinder 120 as it is due to a malfunction in the vaporization device 100, the shutoff valve 130 is When the liquefied petroleum gas flows through and the float 121 is raised by the force of buoyancy, the blocking plate 133 which will be described later blocks the shutoff valve 130 to prevent the liquefied petroleum gas from flowing in a predetermined amount.

On the other hand, the shut-off valve 130 has a sealability to the central portion of the flange portion 130 is fixed through. Such a shutoff valve 130 is formed in a planar hexagon as shown in FIG. 3 or 4 and a plurality of gas outlet holes 131 are drilled toward each side portion, and the hollow portion 134 in the center of the shutoff valve 130 is provided. And a groove 132 that is tapered to the lower end of the hollow part 134 and expands.

In addition, the blocking plate 133 to be integrated into the groove 132 is fixed to the lower end of the fixing rod 123, so that the blocking plate 133 interlocked with the float 121 when the lifting operation by buoyancy is raised. Is to be integrated into the groove 133 to block the further liquefied petroleum gas flows.

Here, the reference numeral 135 is for maintaining the sealability of the flange 140 and the shutoff valve 130 while maintaining the sealability with the blocking plate 133 during the vertical lift operation of the shutoff valve 130. O-ring.

In addition, the natural gas of the liquefied petroleum gas introduced through the shut-off valve 130 is not naturally released from the inner cylinder 120 as in the air as in the prior art, but the drain 129 is disposed below one side of the inner cylinder 120. It is connected to the discharge pipe 126 associated with the drain 129 and its end is connected to the pipe 200 is connected to the combustion means from the upper end of the inner cylinder 120 to be interrupted by the discharge valve 127 do.

Such a discharge valve 127 is a means for operating when natural liquefied petroleum gas to the atmosphere, unlike the pipe that is connected to the inner cylinder 120 to naturally vaporize the liquefied petroleum gas remaining in the inner cylinder 120 In order to flow to the (200) side by operating a separate equalization valve 128 to be connected to the pipe 200 side.

The operating state of the present invention by the above configuration will be described.

After operating the heater 160 installed in the outer cylinder 110 of the vaporizer 100 to set the liquid (water) to always maintain the proper temperature, and associated with the storage tank storing the liquefied petroleum gas When the liquefied petroleum gas is introduced into the vaporization apparatus 100 of the present invention connected by the pipe 200, the liquefied petroleum gas flows along the inlet pipe 150 that wound the inner cylinder 120 several times.

At this time, the length of the flow path of the inlet pipe 150 and at the same time the water inside the outer cylinder 110 is always maintained above the appropriate temperature (that is, the optimum temperature for the conversion of liquefied petroleum gas into the vaporized state) Therefore, when the liquefied petroleum gas flows into the gas inlet hole 125 at the lower end of the inner cylinder 120 side along the inlet pipe 150, the liquefied petroleum gas causes a state change from the liquid phase to the vaporized state.

The petroleum gas in the gas state causing the state change in this way passes through the gas outlet hole 131 formed in the shutoff valve 130 of the inner cylinder 120 and then passes through the upper end of the inner cylinder 120 through a separate pipe. It flows to combustion means, not shown, for combustion, and is used as an energy source.

However, when the temperature of the water in the vaporizer 100 is not maintained at an appropriate level due to various causes such as the malfunction of the heater 160, the liquid liquefied petroleum gas flowing along the inlet pipe 150 is the inner cylinder 120 When the gas is not completely vaporized when the gas is introduced into the tank, the liquefied petroleum gas is introduced into the upper portion of the flange 140 through the gas outlet hole 131 of the shutoff valve 130. Done.

When the liquefied petroleum gas flows to the inside of the inner cylinder 120, that is, to the upper side of the flange 140, to achieve an appropriate level by the occurrence of such a phenomenon, the float provides the buoyancy to the float 121 by the level. 121 is a rising operation, the blocking plate 133, which is fixed to interlock at the lower end of the fixing rod 123, which is fixed and penetrates through the center of the float 121 is operated at the same time.

In this way, the groove 132 of the lower end of the shutoff valve 130 is sealed by the blocking plate 133 that is raised so that the liquid liquefied petroleum gas is no longer introduced into the inner cylinder 120, that is, the flange 140. Will be blocked.

In this case, the petroleum gas in the vaporized state is no longer flowed to the combustion means (not shown) through the upper end side of the inner cylinder 120, and the maintenance of the malfunction in the vaporization device 100 is performed. In order to process the liquid petroleum gas remaining inside the inner cylinder 120, the pressure equalizing valve 128 in the state in which the discharge valve 127 of the discharge pipe 126 associated with one side of the inner cylinder 120 is locked separately. The liquefied petroleum gas remaining in the inner cylinder 120 is naturally vaporized and supplied to the combustion means (not shown) and exhausted.

When the discharge valve 127 is opened in this way, the pipe 200 connected to the discharge pipe 126 and the combustion means is connected, and the liquid liquefied petroleum gas remaining inside the inner cylinder 120 is subjected to its own pressure and natural vaporization. By being discharged to the discharge pipe 126 by the flow to the combustion means in the state of being in communication with the pipe 200 above the inner cylinder 120 at an appropriate pressure to exhaust the remaining liquefied petroleum gas inside the inner cylinder 120 Will be done.

That is, after removing the cause of malfunction of the vaporization device 100 and opening the equalization valve 128 while the outlet valve of the combustion means (not shown) is closed, the remaining liquefied petroleum gas in the inner cylinder 120 is naturally vaporized and discharged. If flowed along 126 and then re-introduced into the inner cylinder 120, that is, the flange portion 140 upper side through the upper end side of the inner cylinder 120, below the flange portion 140 of the inner cylinder 120 The liquefied petroleum gas in the inside flows to the drain 129 side and is made to flow along the discharge pipe 126. Thus, the pressure of the upper portion of the flange 140 and the pressure of the lower portion of the flange 140 of the inner cylinder 120 It is maintained at the same pressure is lowered by the gravity of the float 121 is to be in a normal operation state.

Then, when the outlet valve on the combustion means side is opened again, the normal operation is performed and the petroleum gas in the vaporized state can be supplied to the combustion means.

Eventually, this will eliminate the loss of liquefied petroleum gas and minimize the possibility of safety accidents caused by the outflow.

Therefore, according to the present invention, a phenomenon in which the liquefied petroleum gas flows into the combustion means without being vaporized when an abnormality of the vaporization device occurs is caused by the operation of a float that changes fluidly according to the change in the level of the liquid petroleum gas. Safe operation without power supply prevents liquefied petroleum gas from leaking, and can be expected to be able to actively cope with physical and mechanical operations in case of abnormality.

In addition, the present invention, it is possible to minimize the amount of liquefied petroleum gas flowing into the inner cylinder side according to the operation, and natural vaporization to the combustion means side through a separate discharge pipe without releasing the liquefied petroleum gas introduced into the atmosphere as it is It can be expected to provide an effect that can solve the problems such as waste of energy sources and air pollution caused by being released to the atmosphere by providing.
