Steam exhaust system with separate detection of decanter functions

This creation is about a steam exhaust system, especially a steam exhaust system with separate functions for detecting decanters.

The steam engine mainly heats the water to exceed the boiling point of the water (for example, can reach hundreds of degrees Celsius), and then the water forms high-temperature and high-pressure steam, which is sent to the steam using equipment through the high-pressure pipeline. The steam use equipment is connected to a steam exhaust system through which the steam that has been depressurized and cooled after use is discharged to the outside.

Referring to FIG. 3, the conventional steam exhaust system includes a plurality of discharge lines 50 and a confluence line 51. The input ends of the discharge lines 50 are connected to the steam use device, and the input end of the confluence line 51 is connected to the same. At the output end of the discharge line 50, a heat exchanger 52 and a decanter 53 may be disposed in each of the discharge lines 50, wherein when the steam passes through the decanter 53, condensed water is formed, and thus, The condensed water generated by the decanter 53 is merged into the confluence line 51, and the condensed water is uniformly discharged from the confluence line 51.

However, when the worker observes that the condensate discharge amount of the bus line 51 is reduced, since the condensate discharge amount of the bus line 51 is the total flow rate of the condensed water generated by the decanter 53, the worker only It can be inferred that at least one of the water purifiers 53 has failed, but it is impossible to determine which one of the decanters 53 has failed based on the flow rate of the confluence line 51, causing trouble.

In view of this, the main purpose of this creation is to provide a steam discharge system with separate detection of the decanter function, which allows the staff to individually detect whether the decanter has failed.

The steam discharge system with separate functions for detecting the decanter includes: a plurality of discharge lines, the input ends of the discharge lines are connected to a steam using device; and a confluence line connecting the outputs of the discharge lines a plurality of decanters respectively disposed in the discharge lines; a plurality of first condensate valves respectively disposed in the discharge lines, each of the first condensate valves being located at each of the decanters and the confluence Between the pipelines; a plurality of second condensate valves, the input ends of the second condensate valves are respectively connected to the output ends of the decanters; and a plurality of steam pressure gauges respectively connected to the discharge pipes are located at the The position between the input of the discharge line and the input of the decanter.

According to the present invention, in view of any discharge line, the first condensate valve can be closed to block the path between the discharge line and the confluence line, and the second condensate valve connected thereto is opened. It can be observed whether the second condensate valve discharges the condensed water and the steam pressure value of the steam pressure gauge thereof, thereby separately determining whether the decanter has a fault such as blockage or water leakage, and cannot overcome the prior art. A technical problem to determine which dehydrator has failed.

The decanters are respectively disposed in the discharge lines. In the present embodiment, the decanter includes a first decanter 21 and a second decanter 22, and the first decanter 21 is disposed in the first discharge line 11, the second crucible The water 22 is disposed in the second discharge line 12. The first decanter 21 and the input end of the second decanter 22 receive steam, and the first decanter 21 and the output end of the second decanter 22 respectively discharge condensed water.

The first condensate valves are respectively disposed in the discharge lines and between the output ends of the decanters and the input ends of the confluence lines. As shown in FIG. 1, the present embodiment includes two first condensate valves 31, wherein an input end and an output end of one of the first condensate valves 31 are respectively connected to the output end of the first decanter 21 and At the input end of the bus line 13, the input end and the output end of the other first condensate valve 31 are respectively connected to the output end of the second decanter 22 and the input end of the confluence line 13.

As shown in FIG. 1, the present embodiment includes two second condensate valves 32, one of which has an input end connected to the output end of the first decanter 21 and another second. An input of the condensate valve 32 is coupled to the output of the second decanter 22.

The steam pressure gauges are respectively connected to positions in the discharge lines between the input ends of the discharge lines and the input ends of the decanters. As shown in FIG. 1, the present embodiment includes a first steam pressure gauge 41 and a second steam pressure gauge 42. The first steam pressure gauge 41 is disposed on the first discharge conduit 11 and located in the first hydrophobic water. The input end of the device 21 is configured to measure and display the steam pressure value of the first discharge pipe 11 at the input end of the first decanter 21; the second steam pressure gauge 42 is disposed on the second discharge pipe 12 is located at the input end of the second decanter 22 for measuring and displaying the steam pressure value of the second discharge line 12 at the input end of the second decanter 22; the steam pressure value is available for The user estimates the steam saturation temperature.

The following examples illustrate the use of this creation. When performing routine work at the factory, the worker can open the first condensate valve 31 and close the second condensate valve 32, thereby causing the first puddle 21 and the second damper 22 to generate Condensed water flows into the confluence line 13 through the first condensate valves 31, respectively.

To detect whether the first decanter 21 is faulty, the second condensate valve 32 connected to the first discharge line 11 can be opened and its first condensate valve 31 closed. Thereby, the closed first condensate valve 31 blocks the path between the first discharge line 11 and the confluence line 13, if the first decanter 21 is in a state where the condensed water should not be discharged. The second condensate valve 32 connected thereto has condensed water discharged, indicating that the first sumper 21 has a leak failure. On the other hand, if the input end of the first decanter 21 continuously receives steam, please refer to FIG. 2, and if condensed water 110 is discharged from the second condensate valve 32, the first decanter 21 is represented.

The temperature value is lower than the steam saturation temperature estimated based on the steam pressure value of the first steam pressure gauge 41, that is, the first drainer 21 is blocked, and the first discharge line 11 is feared of internal water accumulation.

The second decanter 22 is detected in the same manner as the first decanter 21, that is, the second condensate valve 32 connected to the second discharge line 12 is opened and the first condensate valve 31 is closed, and observed. Whether the second condensate valve 32 discharges the condensed water and the vapor pressure value of the second steam pressure gauge 42.
