Abstract
The utility model has been announced a kind of 15MW steam-electric power unit condenser jetting vapor extraction device, and it comprises jetting pond, water-jet pump, water-jetting steam extractor, condenser and cooling tower; Jetting pond is connected with cooling tower, and cooling tower connects water-jet pump, and water-jet pump connects water-jetting steam extractor, and water-jetting steam extractor connects respectively condenser and jetting pond, and a port is opened in described cooling tower lower end, connects industrial water pipe.The utility model effect is: this process is simple and reliable, respond well, and the raising of steam-electric power unit condenser vacuum is played a good role, and unit generation amount can improve 2% left and right, saves a large amount of water resources, reaches the object of " saving energy and reduce the cost ".
Description
Technical field
The utility model relates to a kind of 40,000 tons of supporting 15MW steam-electric power of carbon black production line unit condenser jetting vapor extraction devices of producing per year.
Background technology
At present, the technological process of domestic steam-electric power unit condenser jetting vapor extraction device is: to the moisturizing of jetting pond, make pool inner water position maintain certain altitude with industry water, use water-jet pump that pool inner water pressurization is sprayed at a high speed to water-jetting steam extractor.By the ejector principle of high-velocity flow, make to form vacuum in water-jetting steam extractor, water-jetting steam extractor is connected with condenser air pipe.Utilize the high-velocity flow of water-jet pump to extract the incondensable gas of condenser out, to maintain condenser inner height vacuum.The industry water penetrating from water-jetting steam extractor is got back in jetting pond together with the acting exhaust steam (water) condenser, thereby completes the whole jetting process of drawing gas.In this kind of process, shortcoming is that water system sealing can not get cooling, and water temperature can slowly raise, and in the time that water temperature exceedes 50 DEG C, the operating efficiency of water-jet pump will reduce greatly, directly affect Steam Turbine Condenser Vacuum degree, and then affect unit generation amount.Only take the way of industrial moisturizing to lower the temperature.And unnecessary water resource is directly drained from overflow pipe, cause a large amount of wastes of water resource, and effect can not be guaranteed, often affect unit generation amount.
Summary of the invention
The purpose of this utility model is to provide a kind of 15MW steam-electric power unit condenser jetting vapor extraction device, water-jet pump water in this device, from original little closed circulating water system, be modified into the large open water system of cooling naturally, after improvement, can not lower the temperature because mending industry water, and unnecessary water is directly drained from overflow pipe, cause water resource waste, reached the object of " saving energy and reduce the cost ", the industry water of saving per hour is more than 8 tons.
The utility model is achieved like this, a kind of 15MW steam-electric power unit condenser jetting vapor extraction device, it comprises jetting pond, water-jet pump, water-jetting steam extractor, condenser and cooling tower; It is characterized in that: jetting pond is connected with cooling tower, water in described jetting pond is directly delivered to cooling tower, cooling tower connects water-jet pump, water-jet pump connects water-jetting steam extractor, the cooled recirculated water of described cooling tower enters water-jet pump pressurization and sprays in water-jetting steam extractor at a high speed, water-jetting steam extractor connects respectively condenser and jetting pond, the recirculated water that described water jet air ejector penetrates is got back in jetting pond together with the acting exhaust steam water in condenser, flow back to again cooling tower, a port is opened in described cooling tower lower end, connects industrial water pipe.
The advantageous effect that the utility model contrasts original technology is: (1) this technology water-jet pump water, from original little closed circulating water system, be modified into the large open water system of cooling naturally, after improvement, can not lower the temperature because mending industry water, and unnecessary water is directly drained from overflow pipe, cause water resource waste, the former technique of comparing, water resource is fully recycled, and has saved a large amount of water resources, reached the object of " saving energy and reduce the cost ", the industry water of saving per hour is more than 8 tons; (2) this process is simple and reliable, respond well, particularly in summer, not before transformation low vacuum in-0.08MPa, after transformation, can bring up to-0.085MPa, unit can not press because condenser vacuum does not increase load to reduce generated energy, and the raising of steam-electric power unit condenser vacuum is played a good role, and unit generation amount can improve 2% left and right.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In the drawings, 1, jetting pond, 2, water-jet pump, 3, water-jetting steam extractor, 4, condenser,, 5, cooling tower.
Detailed description of the invention
Below in conjunction with brief description of the drawings, embodiment of the present utility model is described in further detail, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof, all should list protection domain of the present utility model in.
As shown in Figure 1, the utility model is to come like this work and enforcement, and it comprises jetting pond 1, water-jet pump 2, water-jetting steam extractor 3, condenser 4 and cooling tower 5; It is characterized in that: jetting pond 1 is connected with cooling tower 5, and cooling tower 5 connects water-jet pump 2, and water-jet pump 2 connects water-jetting steam extractor 3, water-jetting steam extractor 3 connects respectively condenser 4 and jetting pond 1, and a port is opened in described cooling tower 5 lower ends, connects industrial water pipe.
Operation principle of the present invention is: the water after 1 acting of jetting pond is directly delivered to cooling tower 5, cooled recirculated water enters water-jet pump 2 pressurizations and sprays in water-jetting steam extractor 3 at a high speed, due to the jet-action of high-velocity flow, make the interior formation vacuum of water-jetting steam extractor 3, extract the incondensable gas in condenser 4 out, to maintain the high vacuum in condenser 4.The recirculated water penetrating from water jet air ejector 3 is got back in jetting pond 1 together with the acting exhaust steam water condenser 4, then flows back to cooling tower 5, when water level is not enough, suitably mends a little industry waters and keeps cooling tower 5 pool water levels at certain altitude.In the time that summer, circulating water temperature was higher, can suitably make the water source of water-jet pump 2 of a little industry waters, to guarantee that water-jet pump 2 enters coolant-temperature gage and is less than 45 DEG C and ensures condenser vacuum.
