Description
- The present invention relates to a gas supply system, and specifically to a gas supply system in which the pressure of a compressed gas is reduced and the resulting gas is supplied.
- When a compressed gas is supplied from a 47 liter cylinder or a large-sized container, the pressure of the gas is reduced to a specified pressure by a pressure reducing means such as a pressure adjusting equipment, a pressure reducing valve or a control valve, whereby the gas is to be supplied. In this case, since the temperature of the gas whose pressure is reduced by the pressure reducing means is decreased due to adiabatic expansion and Joule-Thomson effect, dew condensation or frost formation occurs on the outer surface of the pressure reducing means, which sometimes makes it difficult to adjust the gas pressure. Accordingly, by heating a pipe on the upstream side of the pressure reducing means (a primary pipe) or by heating the pressure reducing means, decrease in the gas temperature after the pressure is reduced is restrained (for example, see Patent Documents 1 to 3).

06-33858 - However, an electric heater is not preferred to be used as a heat source for heating a pipe of a system which supplies a flammable gas or a pressure reducing means since there is a risk of ignition if a gas leak should occur. Winding a pipe for heating in which a fluid for heating flows around a gas pipe causes a rise in the equipment cost or the operation cost since, in order to raise the temperature of the gas in the gas pipe, it is necessary to make an area for heat transfer extremely large or to make the temperature of fluid flowing in the pipe for heating high.
- On the other hand, since Monosilane (SiH4) or Nitrogen trifluoride (NF3) has a critical pressure very close to the filling pressure, and the critical temperature thereof is also relatively close to room temperature, it is supplied in a state of being filled at the vicinity of the critical point. In addition, since the normal boiling point thereof is high, decrease in the gas temperature due to adiabatic expansion is large and the gas is likely to be liquefied, whereby dew condensation or frost formation frequently occurs on the pressure reducing means. Further, since Monosilane has combustibility and self-combustibility and Nitrogen trifluoride also has a combustion supporting ability, the use of an electric heater is desired to be avoided.
- Accordingly, an object of the present invention is to provide a gas supply system in which the pressure of a compressed gas can be reduced in a stable state and the resulting gas can be supplied, as well as the system has an excellent economy and safety.
- This object is solved by a gas supply system in accordance with the features of claim 1. The sub-claims contain preferred embodiments of the invention.
- In order to attain the above-mentioned object, the gas supply system in the present invention is a gas supply system in which the pressure of a gas supplied from a source of a compressed gas is reduced by a pressure reducing means and the resulting gas is supplied, wherein, on the upstream side, in the gas flow direction, of the pressure reducing means, a heat exchanger which heats the gas by heat exchange of a gas introduced to the pressure reducing means and warm water supplied from a warm water source is provided, as well as, in the pressure reducing means, a warm water flow channel for heating the pressure reducing means by a part of the warm water was provided.
- Further, the gas supply system of the present invention is provided with a warm water circulation means in which the warm water is heated to a temperature of 30 to 40°C and the resulting water is supplied to the heat exchanger and a warm water flow channel of the pressure reducing means. A plurality of the pressure reducing means are arranged in series or in parallel and, on the upstream side, in the gas flow direction, of each of the pressure reducing means, the heat exchanger is arranged. Further, the gas is Monosilane or Nitrogen trifluoride.
- In the gas supply system of the present invention, since a gas is heated by a heat exchanger using warm water as a heat source, a gas flowing in a pipe can be effectively and surely heated, and by heating the pressure reducing means by warm water, a gas after the pressure thereof is reduced can be prevented to be liquefied. By using warm water as a heat source, the safety can be improved as compared with an electric heater. Further, by setting the warm water temperature to not higher than 40°C, the gas temperature does not become too high and energy required for heating can be made small. By providing a plurality of pressure reducing means in series or in parallel, the degree of reduced pressure in each of the pressure reducing means can be optimally configured, and therefore, without generating dew condensation or frost formation on the pressure reducing means or piping systems, a gas whose pressure is reduced can be more effectively supplied, and in particular, a gas such as monosilane or Nitrogen trifluoride can be supplied safely and in a stable state.

For example, in cases where the pressure of a compressed gas whose filling pressure is 9 MPa (absolute pressure, the same hereinafter) is reduced to near the atmospheric pressure and the resulting gas is supplied, the pressure of the gas is reduced to a middle-pressure which is about 4 MPa by afirst pressure regulator 21, and then, the pressure of the resulting gas is reduced to a supply pressure which is near the atmospheric pressure from 4 MPa by asecond pressure regulator 31, whereby the resulting gas is supplied. - Between the gas supply system and the high-
pressure gas container 11, a high-pressure valve 12 and apressure detector 13 are provided, and between the gas supply system and the supply destination, a low-pressure valve 14 is provided. On the upstream side (on the primary side), in the gas flow direction, of each of thepressure regulator heat exchangers shutoff valves pressure regulators pressure detectors water circulation unit 15 which supplies warm water for heating in a circulating manner to thepressure regulators heat exchangers body part 16 on which thepressure regulators heat exchangers - As illustrated in
Fig. 2 , for theheat exchangers coil pipe 42 made of metal is stored in a top-openedcontainer 41 with a bottom (shell-and-coil structure) are used. On the top-opening of thecontainer 41, alid 43 through which anentrance pipe 42a and anexit pipe 42b ofcoil pipe 42 are inserted is detachably attached. On one of opposing sidewalls of thecontainer 41, a warmwater introduction port 44 is provided, and on the other side of the sidewalls, a warmwater discharge port 45 is provided, as well as, inside thecontainer 41, a plurality of baffles (baffle boards) 46 by which warm water which has flowed into thecontainer 41 from the warmwater introduction port 44 is efficiently allowed to be in contact with acoil pipe 42 are provided in such a manner that the baffles are not interfered with thecoil pipe 42. Warm water which has been flowed into thecontainer 41 from the warmwater introduction port 44 flows inside thecontainer 41 while meandering by the effect of thebaffles 46 to be evenly in contact with the outer surface of thecoil pipe 42, and then the gas is heated by heat exchange with a gas flowing inside thecoil pipe 42 through the pipe wall of thecoil pipe 42 to be discharged from a warmwater discharge port 45. - As illustrated in
Fig. 3 , for thepressure regulators water flow channel 53 is provided in such a manner that thechannel 53 surroundsgas flow channels water flow channel 53, a warmwater introduction port 54, and on the other end of the warmwater flow channel 53, a warm water discharge port 55 are provided respectively. Warm water which has flowed in the warmwater flow channel 53 from the warmwater introduction port 54 passes an entrance side ring-shaped flow channel 53a formed on the periphery of thegas flow channel 51, flows into an exit side ring-shaped flow channel 53c from the entrance side ring-shaped flow channel 53a by way of a valve boxperiphery flow channel 53b provided on the periphery of the valve box portion. When warm water flows in each of the flow channels above, it heats thepressure regulators - The warm
water circulation unit 15 is provided with awarm water generator 17 which generates warm water having a preset temperature by using an arbitrary heat energy and a warmwater supply pipe 18 and a warmwater return pipe 19 each of which connects thewarm water generator 17 and objects to be heated in thebody part 16. Thewarm water generator 17 is those in which warm water heated to, for example, a temperature of 30 to 40°C by an electric heater is generated and supplied by a pump, and is formed such that warm water generated in thewarm water generator 17 passes the warmwater supply pipe 18 to branch off into introduction sidebranched pipes 18a corresponding toheat exchangers pressure regulators heat exchangers pressure regulators water return pipe 19 from each of the discharge sidebranched pipes 19a to circulate in thewarm water generator 17 to be recycled. - The temperature of warm water supplied from the
warm water generator 17 can be arbitrarily set depending on conditions such as the supplied gas flow rate, the heat exchange efficiencies of theheat exchangers pressure regulators heat exchangers coil pipe 42, that is, the warm water temperature at the warmwater discharge port 45 is lower than the warm water temperature at the warmwater introduction port 44 by less than 5°C, and preferably 2°C. - On the other hand, for the
coil pipe 42, a pipe having a diameter or thickness depending on a gas flow rate which the supply destination demands and the pressure of the gases passing thecoil pipe 42 is used. Although, by increasing the length of thecoil pipe 42, the gas temperature after performing heat exchange can be made close to the warm water temperature, since a sufficient effect corresponding to the increase in the cost of the pipe to be used cannot be expected, the gas temperature which has been raised by heat exchange with warm water is preferably set to be lower than the warm water temperature by 5°C, and preferably by 3°C. - In this case, heat exchange between a gas flowing in the
coil pipe 42 and warm water flowing on the periphery of thecoil pipe 42 is performed through the pipe wall of thecoil pipe 42. Since this case is not the case of a conventional gas pipe around which a warm water pipe is wound in which two pipes are in line contact with each other on outer surfaces thereof and in which there is an air layer intervening between the pipes, the gas temperature or the like after heat exchange can be easily determined by calculation by setting conditions such as surface areas of the inside and the outside of thecoil pipe 42, the thickness of the pipe wall, the temperature difference between the inside and the outside of the pipe or the specific heat. Accordingly, unlike the conventional case in which the gas temperature cannot be sufficiently raised or in which the gas temperature becomes unstable, gas which flows into thepressure regulator - In the
pressure regulators pressure regulators water flow channel 53 may be set such that dew condensation does not occur on the outer surface of thepressure regulators heat exchangers pressure regulators - Further, although the warm water temperature, the warm water supply capacity of the warm
water circulation unit 15, the heat exchange capacities ofheat exchangers pressure regulators pressure regulators - As illustrated in the present embodiment, by reducing the pressure of the compressed gas in a plurality of steps, the degree of reduced pressure at each step of reducing the pressure can be made small, as well as it becomes not necessary to heat a compressed gas which is to be introduced into a pressure reducing means (
pressure regulators 21, 31) to a high temperature. By heating the gas by theheat exchangers body part 16 provided with piping system in which compressed gas flows and awarm water generator 17 which generates warm water in a state in which they are separated from each other by a separator or the like, even when an electric heater is used for a heat source of thewarm water generator 17, the safety can be considerably improved since the compressed gas and the electric heater are separated. By using warm water, energy required for heating can be reduced as compared with the case in which hot water or steam is used, and heat loss in the piping system becomes small, and if warm water should leak, there is no risk of scald. - When a low-pressure gas after the pressure thereof is reduced is serially supplied to a supply destination, a plurality of gas supply systems provided with the
body part 16 and the warmwater circulation unit 15 may be placed, and one warmwater circulation unit 15 can relate to a plurality ofbody parts 16. When decrease in gas temperature by adiabatic expansion is relatively small, and the pressure of a compressed gas whose degree of reduced pressure is small is reduced and the resulting gas is supplied, only one pressure reducing means and only one heat exchanger can be provided individually. - 11 ... high-pressure gas container, 12 ... high-pressure valve, 13 ... pressure detector, 14 ... low-pressure valve, 15 ... warm water circulation unit, 16 ... body part, 17 ... warm water generator, 18 ... warm water supply pipe, 18a ... introduction side branched pipe, 19 ... warm water return pipe, 19a ... discharge side branched pipe, 21, 31 ... pressure regulator, 22, 32 ... heat exchanger, 23, 33 ... shutoff valve, 24, 34 ... pressure detector, 41 ... container, 42 ... coil pipe, 42a ... entrance pipe, 42b ... exit pipe, 43 ... lid, 44 ... warm water introduction port, 45 ... warm water discharge port, 46 ... baffle, 51, 52 ... gas flow channel, 53 ... warm water flow channel, 53a ... entrance side ring-shaped flow channel, 53b ... valve box periphery flow channel, 53c ... exit side ring-shaped flow channel, 54 ... warm water introduction port, 55 ... warm water discharge port
