[0002] The high-temperature wastewater of condensing coal-fired power plants mainly comes from the high-salt wastewater of the steam drum and ash washing water of the unit. Such high-temperature industrial wastewater is usually collected together in the drainage trough of the unit. Due to the high water temperature, a large amount of water vapor is formed in the drainage trough, and the industrial water cooling effect of the boiler fixed discharge device is unstable, especially during the start-up and shutdown of the unit, the cooling effect is poor, and a large amount of steam leaks out, resulting in the loss of water resources and heat.
[0003] For ultra-low emission units with qualified environmental protection facilities, the composition of "white smoke" is mainly water mist, and the concentration of pollutants is very low. It has no direct impact on environmental quality and is considered visual pollution. Cooling the steam and taking water to make the steam meet environmental protection requirements such as exhaust temperature and humidity, eliminating the "white smoke", can not only eliminate the visual impact, but also be used as a safety application on site to prevent hot steam from overflowing and injuring people. In general, the steam leakage from the drainage trough of a thermal power plant not only wastes water resources and energy, but also the high temperature of the steam has a certain impact on the safety of the surrounding environment. How to economically and effectively solve the problem of steam leakage in thermal power plants has become a problem that thermal power plants must face. Utility Model Content

[0022] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0023] like Figure 1-2As shown, the utility model is an unpowered steam absorber device for an industrial wastewater treatment system of a thermal power plant, comprising a cylinder 11, characterized in that it also includes a breathing tube 1, a cleaning tube 2, a drain pipe 3, a filler 4, a grille plate 5, a lifting ear 6, a steam port 7, a partition plate 8, a bracket 9, a cleaning tube 2 support plate and a top plate 12, wherein the top plate 12 is provided on the top of the cylinder 11, a cleaning tube 2 support plate is provided inside the cylinder 11, a cleaning tube 2 support plate is provided on the top of the cleaning tube 2 support plate, one end of the cleaning tube 2 is provided on the outside of the cylinder 11, a bracket 9 is provided at the bottom of the inner cavity of the cylinder 11, a matching grille plate 5 is provided on the top of the bracket 9, and lifting ears 6 are provided at both ends of the breathing tube 1 located at the top of the top plate 12, and two groups of lifting ears 6 are provided.
[0024] In one embodiment, a drain pipe 3 is provided on one side of the outer wall of the cylinder 11, the water inlet of the drain pipe 3 is provided inside the cylinder 11, the water outlet of the drain pipe 3 is provided outside the cylinder 11, a filler 4 is provided inside the cylinder 11, and a steam port 7 is provided on one side of the outer wall of the cylinder 11, and the steam port 7 is on the same side as the drain port of the cleaning pipe 2.
[0025] In this embodiment, specifically: after the steam enters the steam absorption device from the steam port 7, the hot steam will rise, and after being evenly distributed through the grid plate 5, it will fully contact the filler. The steam consumes energy during the collision with the grid 5 and the filler 4, condenses into liquid water droplets, and finally falls to the bottom of the absorber under the action of gravity. When the condensed water at the bottom of the absorber accumulates to the same level as the drain pipe, the drain pipe 3 starts to drain water out.
[0026] In one embodiment, a matching partition 8 is provided at the bottom of the inner cavity of the cylinder 11, a 90-degree elbow is provided at the water inlet of the drain pipe 3, the water inlet of the drain pipe 3 faces downward, and the top of the partition 8 is flush with the water inlet of the drain pipe 3.
[0027] In this embodiment, specifically: in order to prevent steam from being discharged directly from the drain pipe 3 after entering the absorber, a 90-degree elbow is set at the inlet of the drain pipe 3, and the inlet is facing downward. At the same time, a partition 8 is set next to the drain pipe, and the top of the partition 8 is flush with the inlet of the drain pipe. When the water level at the bottom of the absorber exceeds the partition 8, a liquid seal is formed in the drain pipe 3 to prevent steam from escaping from the drain pipe 3.
[0028] In one embodiment, a breathing tube 1 is provided in the middle of the top of the top plate 12, a 180-degree curved pipe section is provided at the top end of the breathing tube 1, and a breathing port of the breathing tube 1 is vertically downward.
[0029] In this embodiment, specifically: during the process of continuous absorption of steam, more and more non-condensable gas brought by the steam gathers in the upper part of the absorber, and the pressure in the upper part of the absorber gradually increases. A breathing port of the breathing tube 1 is set on the top of the device to relieve pressure and protect the device. The breathing tube 1 is set with a 180° bent pipe section, and the breathing port of the breathing tube 1 is vertically downward to prevent the high-temperature gas in the tube from hurting people.
[0030] In one embodiment, the surface of the cleaning pipe 2 is provided with a plurality of groups of round hole.
[0031] In this embodiment, specifically: the cleaning pipe 2 is located at the upper part of the device and is connected to the cleaning water supply pipe. The round holes of the packing 3 are cleaned regularly, so that the working performance of the unpowered steam absorber device can be guaranteed.
[0032] In one embodiment, a company used the device of the present invention to eliminate the external steam from the drainage troughs of units 1-7. The results showed that after using the device of the present invention, the external steam from the drainage troughs of the units was effectively absorbed, the steam absorber operated continuously and normally, and the equipment was maintained once a year, which saved resource consumption, reduced investment and operating costs, and was highly economical.
[0033] Working principle: The steam port 7 is on the same side as the drain port and is located at the bottom of the device. After the steam enters the steam absorption device from the steam port 7, the hot steam will rise, and after being evenly distributed through the grid plate 5, it will fully contact with the filler 4. The steam consumes energy in the process of colliding with the grid and the filler 4, condenses into liquid water droplets, and finally falls to the bottom of the absorber under the action of gravity. When the condensed water at the bottom of the absorber accumulates to the same height as the drain pipe 3, the drain pipe 3 starts to drain water out.
[0034] In order to prevent steam from being discharged directly from the drain pipe 3 after entering the absorber, a 90-degree elbow is set at the inlet of the drain pipe 3, with the inlet facing downward. At the same time, a partition 8 is set next to the drain pipe 3, and the top of the partition 8 is flush with the inlet of the drain pipe 3.
[0035] When the water level at the bottom of the absorber exceeds the partition 8, a liquid seal is formed in the drain pipe 3 to prevent steam from escaping from the drain pipe 3. As the steam is continuously absorbed, more and more non-condensable gas brought by the steam gathers in the upper part of the absorber, and the pressure in the upper part of the absorber gradually increases. A breathing port is set at the top of the device for pressure relief and protection. The breathing pipe 1 is set with a 180-degree bend section, and the breathing port is vertically downward to prevent the high-temperature gas in the pipe from hurting people.
[0036] The cleaning pipe 2 is located at the upper part of the device and is connected to the cleaning water supply pipe. The round holes of the packing 4 are cleaned regularly, so that the working performance of the unpowered steam absorber device can be guaranteed.
[0037] The above is the overall working process of the utility model, and you can repeat this step next time you use it.
