[0030] Embodiment one

[0031] As Figure 1 shown, the present application provides a drainage device, which comprises a downpipe, a warning mechanism and a body. The downpipe comprises a first pipe section, a second pipe section and a third pipe section from top to bottom. The first pipe section of the downpipe is connected to a drainage port of a gas pipe. The warning mechanism is arranged on the downpipe. The third pipe section of the downpipe is inserted into the body.

[0032] In some embodiments, as Figure 1 shown, the first pipe section and the third pipe section are arranged vertically, and the second pipe section is arranged obliquely. When the condensed water flows downward, the obliquely arranged second pipe section can play a buffering role. When the condensed water contains residues, the obliquely arranged second pipe section can also reduce the impact of the residues on the pipe, thereby avoiding pipe damage.

[0033] Specifically, in some embodiments, in order to control the flow rate of the condensed water and alleviate the impact of the condensed water on the pipe, the angle between the second pipe section and the horizontal line is controlled to be greater than 30° and less than 75°.

[0034] In some embodiments, a primary valve 1 is arranged on the first pipe section, and a secondary valve 2 is arranged on the third pipe section. The primary valve 1 and the secondary valve 2 can be manually opened and closed to connect and disconnect the gas pipe and to transport the condensed water.

[0035] In some embodiments, the warning mechanism comprises a pressure transmitter 3, an electric quick cut valve 4 and a controller. The pressure transmitter 3 is arranged on the first pipe section and below the primary valve 1. The electric quick cut valve 4 is arranged on the third pipe section and above the secondary valve 2. The controller is electrically connected to the pressure transmitter 3 and the electric quick cut valve 4. The pressure transmitter 3 is used to detect the pressure inside the downpipe and to transmit real-time data to the controller. When the real-time data exceeds a set pressure value, the controller controls the electric quick cut valve 4 to disconnect the downpipe from the gas pipe.

[0036] In some embodiments, the early warning mechanism further comprises an alarm, which is arranged on the downcomer. When the real-time data is greater than the set pressure value, the controller controls the alarm to alarm.

[0037] In some embodiments, the body comprises at least two chambers 5; the third pipe section of the downcomer is inserted into the first chamber 5, and the overflow port 6 is arranged on one side of the last chamber 5.

[0038] In some embodiments, the drainage device further comprises a water collecting well 7, which is arranged below the overflow port 6 and is used for collecting condensed water.

[0039] In some embodiments, the upper end of the chamber 5 is provided with an exhaust valve 8, which is used for water replenishment and exhaust of the chamber 5 when the chamber 5 is in a state of water shortage or excessive pressure.

[0040] In some embodiments, the bottom end of the chamber 5 is provided with a sewage valve 9, which is used for sewage discharge when the chamber 5 and the downcomer are cleaned.

[0041] In some embodiments, the drainage device further comprises a detection port 10, which is arranged on the downcomer and is used for detecting whether the downcomer is blocked or damaged.

[0042] In some embodiments, in combination with Figure 1 As shown in the figure, the body comprises four chambers 5, the third pipe section of the downcomer is inserted into the first chamber 5, and the overflow port 6 is arranged on one side of the fourth chamber 5. Under the normal operation of the drainage device, the primary valve 1 and the secondary valve 2 are in the fully open state, the exhaust valve 8, the detection port 10 and the sewage valve 9 are in the fully closed state, the overflow port 6 is in communication with the atmosphere, and the condensed water in the coal gas or gas pipeline flows into the body through the downcomer, and then flows out of the overflow port 6 through the four chambers 5 in turn. During the collection of the condensed water, the water seal liquid level 11 in the first chamber 5 is controlled at 1020mm, the pressure value of each chamber 5 is 10KPa, the pressure value of the four chambers is 40KPa, and the set pressure value of the detection should be less than 35KPa, so that the early warning management needs to be made. In this embodiment, when the pressure transmitter 3 detects that the pressure in the downcomer is 30KPa, the PLC controller controls the electric quick-change valve 4 to immediately close, which effectively prevents the coal gas or gas accident caused by the drainage device being punctured due to the pressure in the downcomer exceeding 40KPa under abnormal pressure fluctuation.
