Abstract

(57) [Summary] [Purpose] To prevent the drain water from being discharged together with the exhaust gas from the exhaust pipe of the gas engine heat pump and to pollute the surroundings of the installation site. [Structure] Weir plates 3a and 3b are provided below the upper and lower opening end surfaces 2a and 2b of a bent tube 1 composed of upper and lower horizontal portions 1a and 1b and a vertical portion 1c in the middle thereof, and opening ends 2b are provided in the lower horizontal portion 1b. The tip end opening 4a of the exhaust supply pipe 4 inserted from above is bent upward at the lower end of the vertical portion 1c, and the drain hose joint 6 is connected to the drain port 5 formed at the bottom of the lower horizontal portion 1b. . [Effect] Although the drain water is separated from the engine exhaust and the drain water is exhausted to the drain, it has an extremely simple structure in which the L-shaped exhaust supply pipes 4 and 4a are inserted into the crank-shaped bent pipe 1. Can be discharged into the air at a height that does not disturb the surroundings, so the surroundings of the GHP body 8 can be contaminated with drain water as in the conventional case, or exhaust gas can enter the drain pipe of the dwelling unit through the drainage channel. There is no risk of inconvenience, and the installation work can be done easily at low cost.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas-liquid separator attached to an exhaust pipe of a GHP gas engine or the like.

[0002]

[Prior art]

 Fig. 3 shows the appearance of an early GHP outdoor unit in which the GHP (gas engine heat pump) was developed. The engine exhaust pipe is located below the GHP body 8 and is usually suitable for this. Connect a length of rubber pipe 9 to discharge the exhaust gas to the outside on the ground as shown in the figure, or extend the rubber pipe 9 to a nearby drainage channel to allow the drain water together with the exhaust gas to enter the drainage channel. It was discharged.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional configuration, there is a problem in that the water contained in the exhaust gas is condensed together with the exhaust gas and is discharged as drain water, and the drain water pollutes the vicinity of the outdoor unit installation location. In addition, in order to avoid this, some users extend the rubber pipe and insert it into the drainage channel.In this case, the exhaust gas enters the drainage channel from the drainage channel, and the exhaust gas leaks at other places, causing There was a problem that it was easy to cause trouble to. The present invention solves such problems, and an object thereof is to provide an exhaust pipe gas-liquid separator that separates exhaust gas and drain water so that exhaust gas can be discharged into the air and drain water can be discharged into a drain. It is what

[0004]

[Means for Solving the Problems]

 As shown in FIG. 1, a gas-liquid separator for an exhaust pipe according to the present invention has a weir plate at the bottom of the upper and lower open end faces 2a, 2b of a bent pipe 1 composed of upper and lower horizontal portions 1a and 1b and a vertical portion 1c in between. 3a and 3b are provided, and the tip end opening 4a of the exhaust gas supply pipe 4 inserted into the lower horizontal portion 1b from the opening end 2b is bent upward at the lower end portion of the vertical portion 1c, and at the same time the lower horizontal portion 1b is A drainage hose joint 6 is connected to the drainage port 5 formed at the bottom.

[0005]

[Action]

 At the time of use, as shown in FIG. 2, the bent pipe 1 is attached to the GHP body 8 by the fitting 7, and the exhaust pipe of the engine is connected to the outer end of the exhaust supply pipe 4 via the rubber pipe 9. . The exhaust gas of the engine is ejected from the tip end opening portion 4a of the exhaust gas supply pipe 4, rises in the vertical portion 1c of the bending pipe 1, passes through the upper horizontal portion 1a, and is discharged to the outside from the upper opening end 2a. It At this time, the mist-like water droplets contained in the exhaust gas collide with the upper surface of the inner wall of the upper horizontal portion 1a at the upper end portion of the vertical portion 1c and travel down the inner wall surfaces of the upper horizontal portion 1a and the vertical portion 1c. Then, the water is collected in the lower horizontal portion 1c and drained from the drainage port 5.

[0006]

【Example】

 FIG. 1 shows an embodiment of a gas-liquid separator for an exhaust pipe according to the present invention, in which a bent pipe 1 is an upper L-shaped elbow in which a weir plate 3a is fixed to a lower part of an opening face 2a at a horizontal end of the upper pipe. The flat portion 1a, the straight tubular vertical portion 1c, and the straight tubular lower horizontal portion 1b in which the L-shaped elbow 10 is fixed to one end and the weir plate 3b is provided below the other end opening surface 2b, The length of the part 1c is adjusted and cut according to the local situation, and is connected with an adhesive. The exhaust supply pipe 4 to be inserted into the lower horizontal part 1b from its open end 2b and the bending of the tip thereof. The joint with the opening 4a is performed by inserting the elbow 4a forming the bent opening 4a from above the elbow 10 before the vertical portion 1c and the elbow 10 are bonded. A drain port 5 is formed in the bottom of the lower horizontal portion 1b, and a drain hose joint 6 is screwed into the drain port 5.

At the time of attachment, first, the lower horizontal portion 1a is attached to an appropriate location of the GHP main body 8 by the attachment metal fitting 7, and the exhaust supply pipe 4 and the bending opening portion 4a are inserted and joined in the elbow 10. Then, the vertical pipe 1c is adjusted to an appropriate length and joined to the elbow 10, and then the upper horizontal portion 1a is joined to the upper end of the vertical pipe 1c with the open end 2a oriented in an appropriate direction. At this time, the bent opening 4a prevents the exhaust gas supply pipe 4 from coming off. Further, the exhaust rubber pipe 9 is connected to the outer end of the exhaust supply pipe 4, the drain hose 11 is connected to the drain hose joint 6, and the installation work of the gas-liquid separator is completed.

When the GHP is operated using the gas-liquid separator of the present invention, the engine exhaust gas is ejected upward from the tip opening 4a of the exhaust supply pipe 4, hits the inner wall surface of the upper horizontal portion 1a, and is discharged. The contained mist-like water droplets adhere to the inner wall surface, flow down along the upper horizontal portion 1a and the vertical portion 1c, are collected in the lower horizontal portion 1c, are discharged from the drain port 5, and are separated into exhaust gas. Only the gas is discharged from the tip end opening 2a of the upper horizontal portion 1a. The upper end of the bent opening 4a at the tip of the exhaust supply pipe 4 is cut obliquely so that when exhaust gas is ejected at high speed, the air column of a certain wavelength resonates and "noise" is generated. The hole 12 provided at the bottom of the bent opening 4a is for preventing drain water from collecting there.

[0009]

[Effect of device]

 According to the configuration of the present invention, the drain water is separated from the exhaust gas of the engine by inserting the L-shaped exhaust supply pipes 4 and 4a into the crank-shaped bent pipe 1 and separating the drain water from the exhaust gas of the engine. The exhaust can be discharged into the air into the drain at a height that does not disturb the surroundings. Therefore, the area around the GHP body 8 can be polluted with drain water as in the past, or the exhaust gas can be discharged from the drain into the dwelling unit. There is an advantage that there is no danger of invading the drainage pipe of the plant and causing trouble, and the installation work can be done easily at low cost.
