Description

Technical Field

[0001] The utility model relates to the technical field of drain devices, in particular to a steam pipeline drain device. Background Art

[0002] The main steam system refers to the system composed of the main steam pipeline, valves, drain devices and steam branches leading to the new steam equipment from the boiler superheater outlet manifold to the turbine inlet main steam valve. For power plants equipped with intermediate reheat units, it also includes the reheat cold section pipeline and valves from the turbine high-pressure cylinder exhaust to the boiler reheater inlet manifold and the reheat hot section pipeline and valves from the reheater outlet manifold to the turbine intermediate-pressure cylinder inlet valve.

[0003] The existing steam pipe drain device is provided with a drain box connected to the tail end of the steam pipe, and the high-temperature steam is cooled into water through the drain box, but the water formed by the steam still has a certain temperature, causing the water vapor to gather in the drain box and affecting the cooling efficiency. To this end, we propose a steam pipe drain device. Utility Model Content

[0004] The main purpose of the utility model is to provide a steam pipe drainage device, which can cool and drain water vapor through a dredging mechanism and a collecting mechanism, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A steam pipe drain device comprises an air intake pipe and a dredging mechanism, wherein the dredging mechanism is installed at one end of the air intake pipe, and the dredging mechanism is composed of a connecting pipe, a drain valve, a U-shaped pipe and a heat conduction plate. One end of the air intake pipe is connected to one end of the connecting pipe through the drain valve, and the other end of the connecting pipe is welded with a U-shaped pipe, and a heat conduction plate is welded to the pipe wall of the U-shaped pipe.

[0007] Furthermore, it also includes a collecting mechanism, which is installed on the tube wall of the U-shaped tube and can collect condensed water.

[0008] Furthermore, the collecting mechanism is composed of a tank body, a cooling plate, heat sinks and a honeycomb tube. The U-shaped tube is welded to the tank body at the tube wall, a honeycomb tube is installed on the inner wall of the tank body, a cooling plate is welded to the tube wall of the honeycomb tube, and the cooling plate runs through the tank body, and several groups of heat sinks are welded to the plate wall of the cooling plate. The honeycomb tube can perform secondary cooling on the condensed water.

[0009] Furthermore, a vertical pipe is welded to the tank wall of the tank body to facilitate water discharge.

[0010] Furthermore, an openable valve is installed on the wall of the vertical pipe to facilitate personnel to open it.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when draining the steam pipe, since a dredging mechanism is installed at one end of the air inlet pipe, the dredging mechanism is composed of a connecting pipe, a drain valve, a U-shaped tube and a heat conduction plate. After the steam pipe is connected to the air inlet pipe, a person opens the drain valve to allow steam to enter the U-shaped tube through the drain valve, and the U-shaped tube condenses the water vapor. Since a heat conduction plate is welded at the tube wall of the U-shaped tube, the heat conduction plate cools the U-shaped tube by heat conduction. When collecting the condensed water, since a collecting mechanism is installed at the tube wall of the U-shaped tube, the collecting mechanism is composed of a tank body, a cooling plate, a heat sink and a honeycomb tube. After the cooled water enters the tank body, since a honeycomb tube is installed at the inner wall of the tank body, and a cooling plate is welded at the outer wall of the honeycomb tube, after the condensed water enters the honeycomb tube, the honeycomb tube transfers heat to the cooling plate, and the cooling plate dissipates heat to the heat sink, thereby increasing the dredging effect.

Since a heat conduction plate 204 is welded on the pipe wall of the U-shaped pipe 203, the heat conduction plate 204 conducts heat conduction cooling on the U-shaped pipe 203. When collecting the condensed water, since a collecting mechanism 3 is installed on the tube wall of the U-shaped tube 203, and the collecting mechanism 3 is composed of a tank body 301, a cooling plate 302, a heat sink 303 and a honeycomb tube 304, after the cooled water enters the tank body 301, since a honeycomb tube 304 is installed on the inner wall of the tank body 301, and a cooling plate 302 is welded on the outer wall of the honeycomb tube 304, after the condensed water enters the honeycomb tube 304, the honeycomb tube 304 transfers the heat to the cooling plate 302, and the cooling plate 302 dissipates the heat to the heat sink 303, thereby increasing the dredging effect.
