Example two
FIG. 2 is a schematic view of an exhaust system according to another embodiment of the present invention; please refer to fig. 2. In the present embodiment, in addition to the first embodiment, the exhaust pipe 300 of the exhaust apparatus of the present embodiment is provided with the second stop valve 320, and the oil supply pipe 400 is provided with the third stop valve 410.

The bubbles in the heat transfer oil pipe 100 are always introduced into the expansion tank 200 along the exhaust pipe 300 in a bubble shape due to the low density.
The exhaust apparatus that this embodiment provided includes heat conduction oil pipe 100 and expansion tank 200, expansion tank 200 sets up the top at heat conduction oil pipe 100, be equipped with the blast pipe 300 and the oil pipe 400 of mending that link to each other with the expansion tank on the heat conduction oil pipe 100, blast pipe 300 is close to heat conduction oil pipe 100's oil feed end, the lower extreme of blast pipe 300 links to each other with heat conduction oil pipe 100's upper surface, the upper end of blast pipe 300 extends to the inside liquid level top that just is located the expansion tank 200 of expansion tank 200, mend the liquid level below that oil pipe 400 extends to in the expansion tank 200.

Since the pressure in the expansion tank 200 is increased due to the gas discharged to the expansion tank 200, in order to maintain the pressure balance of the entire exhaust apparatus, the liquid in the expansion tank 200 is pressed into the heat transfer oil pipe 100 through the oil compensating pipe 400 under the pressure. Through the above process, the present embodiment reduces the gas content in the heat conduction oil pipe 100, thereby reducing the potential safety hazard.
EXAMPLE III
FIG. 3 is a schematic view of an exhaust apparatus according to yet another embodiment of the present invention; please refer to fig. 3. In the present embodiment, on the basis of the second embodiment, the exhaust device of the present embodiment is provided with an exhaust valve 210 at the top of the expansion tank 200, and the exhaust valve 210 can exhaust excessive gas in the expansion tank 200, so as to maintain the pressure inside the whole exhaust device within a preset range and adjust the liquid level position in the expansion tank 200.
Further, in this embodiment, the expansion tank 200 is further connected to an overflow pipe (not shown in the figure), and the overflow pipe is provided with an overflow valve. The liquid level in the expansion tank 200 can be controlled by arranging the overflow valve, when the liquid level in the expansion tank 200 is too high, oil-gas separation and space gas discharge in the expansion tank 200 are not clean, and when the liquid level in the expansion tank 200 reaches the overflow liquid level, the overflow valve is opened to enable the liquid in the expansion tank 200 to flow out, so that the liquid level in the expansion tank 200 is kept not to be ultrahigh; when the liquid level in the expansion tank 200 is lower than the overflow level, the overflow valve is closed, so that the liquid in the expansion tank 200 cannot flow out through the liquid outlet. The liquid level height in the expansion tank 200 can be well ensured through the arrangement of the overflow valve.
In this embodiment, the exhaust valve 210 is closed during normal operation and is opened when the pressure is too high to allow exhaust. The height of the mouth of the overflow pipe in the expansion tank 200 should be lower than the lower end position of the separation hole 310 on the exhaust pipe 300. This prevents the oil from flooding the exhaust pipe 300 and the separation holes 310, and facilitates the exhaust.
The exhaust apparatus that this embodiment provided includes heat conduction oil pipe 100 and expansion tank 200, expansion tank 200 sets up the top at heat conduction oil pipe 100, be equipped with the blast pipe 300 and the oil pipe 400 of mending that link to each other with the expansion tank on the heat conduction oil pipe 100, blast pipe 300 is close to heat conduction oil pipe 100's oil feed end, the lower extreme of blast pipe 300 links to each other with heat conduction oil pipe 100's upper surface, the upper end of blast pipe 300 extends to the inside liquid level top that just is located the expansion tank 200 of expansion tank 200, mend the liquid level below that oil pipe 400 extends to in the expansion tank 200. In the embodiment, the exhaust pipe 300 connected with the expansion tank 200 is arranged, the lower end of the exhaust pipe 300 is connected with the upper surface of the heat conduction oil pipe 100, and as the density of the gas is less than that of the heat conduction oil, when the heat conduction oil is mixed with the gas, most of the gas is in a bubble shape and is positioned above the heat conduction oil in the heat conduction oil pipe 100, so that the gas enters the exhaust pipe 300; since the upper end of the gas exhaust pipe 300 extends above the liquid level in the expansion tank 200, the gas mixed in the conduction oil is discharged into the headspace of the expansion tank 200. Since the pressure in the expansion tank 200 is increased due to the gas discharged to the expansion tank 200, in order to maintain the pressure balance of the entire exhaust apparatus, the liquid in the expansion tank 200 is pressed into the heat transfer oil pipe 100 through the oil compensating pipe under the pressure. Through the above process, the present embodiment reduces the gas content in the heat conduction oil pipe 100, thereby reducing the potential safety hazard.
Example four
FIG. 4 is a schematic view of an exhaust apparatus according to yet another embodiment of the present invention; FIG. 5 is an enlarged view of a portion of the exhaust tube and heat transfer oil tube of FIG. 4; FIG. 6 is an axial view of FIG. 5; please refer to fig. 4-6. In the present embodiment, on the basis of the third embodiment, the lower end of the exhaust pipe 300 in the exhaust apparatus of the present embodiment extends into the heat conduction oil pipe 100, and the lower end surface of the exhaust pipe 300 is an inclined surface, and the inclined surface is inclined toward the oil inlet direction of the heat conduction oil pipe 100. In this embodiment, the length of the exhaust pipe 300 extending into the heat conduction oil pipe 100 can be set as required, and generally, the length is smaller than or equal to the inner radius of the heat conduction oil pipe 100, so as to ensure the normal flow of the liquid in the heat conduction oil pipe 100. Because the bubbles in the liquid generally float on the upper side of the liquid, namely in the heat conduction oil pipe 100, the bubbles are located at the top of the pipe cavity, when the bubbles flow along with the liquid in the heat conduction oil pipe 100, because the lower end of the exhaust pipe 300 extends into the heat conduction oil pipe 100, and the lower end surface of the exhaust pipe 300 inclines towards the oil inlet direction of the heat conduction oil pipe 100, the bubbles in the liquid can more easily enter the exhaust pipe 300, so that the bubbles can better enter the top space of the expansion tank 200 along the exhaust pipe 300, and the exhaust effect in the heat conduction oil pipe 100 is improved.
Further, the angle between the inclined surface and the heat transfer oil pipe 100 in this embodiment is in the range of 40-60 ° to better guide the bubbles into the headspace of the expansion tank 200.
The slope can automatically adapt to the amount of bubbles in the heat conducting oil pipe 100, that is, after the gas enters the slope of the exhaust pipe 300, the oil can be supplemented quickly, so that the slope is submerged. The upper end of the gas discharge pipe 300 is located above the liquid level in the expansion tank 200 so that the introduced gas bubbles can be rapidly introduced into the head space of the expansion tank 200 without being obstructed by the oil.
