Description

Technical Field

[0001] The utility model relates to the technical field of water jetting and air pumping devices, in particular to a water jetting and air pumping device with high efficiency heat dissipation of a heater. Background Art

[0002] At present, during the startup process of thermal power generation units, the boiler needs to be ignited to warm up the machine. At this time, more steam will enter the condenser. If a certain vacuum is not established in the condenser, a large amount of steam entering the condenser will cause the condenser to form a positive pressure and damage the equipment. Therefore, the establishment of vacuum in the condenser is an indispensable condition for the turbine to run. The condenser can be vacuumed by a water jet pumping device, which is also called a water jet steam extractor. It is a vacuum product. There are two ways to supply water to the water jet pumping device. One is an open water supply method. The working water is drawn from the condenser circulating water inlet pipe by a special water jet pump. The gas and water mixture discharged after the vacuum pump is drawn to the condenser circulating water outlet pipe. The other is a closed circulation water supply method, which is equipped with a special working water tank. The water jet pump sucks working water from the water inlet tank and discharges it to the return water tank after the vacuum pump works. The return water tank is connected to the water inlet tank by a connecting pipe, so the water returns to the water inlet tank. To prevent the water temperature from rising too much, cold water is continuously added during operation, and a portion of the water with increased temperature is discharged through the overflow port.

[0003] However, the existing closed-loop water supply water jetting and air extraction device has low heat dissipation efficiency, and requires staff to frequently add cold water into the working water tank for neutralization and cooling, which increases the workload of the staff. After the working water tank has been working for a long time, scale is easily deposited inside. The scale accumulation occupies the internal space of the working water tank and reduces the water storage capacity. The scale is also easy to block the water outlet. In order to solve the shortcomings of the existing technology, we propose a heater with high efficiency heat dissipation water jetting and air extraction device. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3As shown, a heater high-efficiency heat dissipation water jetting and exhaust device comprises a water jetting and exhaust device body 1, a heat conduction component 2 is arranged on the outside of the water jetting and exhaust device body 1, and the heat conduction component 2 comprises a protective cover 13. When the steam temperature in the water jetting and exhaust device body 1 is increased due to the mixed air intake pipe 3, the staff starts the heat dissipation fan 15. At this time, the heat of the water jetting and exhaust device body 1 is uniformly dissipated into the cavity formed between the protective cover 13 and the water jetting and exhaust device body 1 through the conduction of the heat conduction sheet 14. The heat dissipation fan 15 discharges the hot air in the cavity and conducts The heat sheet 14 conducts heat to the protective cover 13, and dissipates heat through the outside of the protective cover 13 at the same time, thereby improving the heat dissipation efficiency. At the same time, the stirring assembly 8 quickly fuses the cold water injected by the staff through the water injection port opened on the working water tank 7, thereby accelerating the fusion of cold water and high-temperature water and improving the cooling efficiency. The high-pressure water pump 10 draws the cooled water after fusion in the working water tank 7 through the second connecting pipe 11 and sends it to the nozzle 12 in the water jetting and air extraction device body 1, further reducing the temperature in the water jetting and air extraction device body 1, cooling down both inside and outside, improving the cooling effect, and cooling down faster.

[0023] like Figure 2 and Figure 4 As shown, a stirring assembly 8 is arranged at the top center of the working water tank 7, and the stirring assembly 8 includes a mounting frame 16. When scale is generated inside the working water tank 7, the staff starts the driving motor 17 at this time, and the output end of the driving motor 17 drives the stirring rod 18 to rotate, and the stirring rod 18 drives the fixed rod 19 to drive the stirring rope 20 to stir in the working water tank 7. Under the continuous beating of the stirring rope 20, the scale deposited at the bottom of the working water tank 7 cannot gather into blocks. When there is too much water in the working water tank 7, it overflows through the overflow port opened at the top of the working water tank 7, thereby processing the scale. The scale no longer accumulates and occupies the internal space of the working water tank, thereby ensuring the water storage capacity.

[0024] How it works

[0025] It should be noted that the utility model is a water jetting and air extraction device with high efficiency in heat dissipation for a heater. When in use, firstly start the high-pressure water pump 10 to extract the water stored in the working water tank 7 through the connected first connecting pipe 9. The high-pressure water pump 10 sends the water extracted from the working water tank 7 to the nozzle 12 through the second connecting pipe 11. The water pressurized by the high-pressure water pump 10 is ejected from the opening of the nozzle 12 located in the main body 1 of the water jetting and air extraction device. The nozzle 12 quickly ejects the pressurized water to form a high vacuum in the main body 1 of the water jetting and air extraction device. The main body 1 of the water jetting and air extraction device is in a negative pressure state and steam is extracted through the air intake pipe 3. The steam enters the main body 1 of the water jetting and air extraction device through the air intake pipe 3 and aggregates with the water ejected from the nozzle 12 at the mixing pipe 4. The water ejected from the nozzle 12 is The steam is condensed and fused, and the fused high-temperature water is transported to the pressure-reducing pipe 6 through the mixing pipe 4 and the throat 5. The fused high-temperature water is decompressed through the pressure-reducing pipe 6 and then transported to the working water tank 7. Then the staff injects cold water through the water injection port opened on the working water tank 7. At this time, the drive motor 17 is started, and the output end of the drive motor 17 drives the stirring rod 18 to rotate. The stirring rod 18 drives the fixed rod 19 to drive the stirring rope 20 to stir in the working water tank 7, thereby accelerating the fusion of cold water and high-temperature water and improving the cooling efficiency. At the same time, under the continuous pumping of the stirring rope 20, the scale deposited at the bottom of the working water tank 7 cannot gather into blocks. When there is too much water in the working water tank 7, it overflows through the overflow port opened on the top of the working water tank 7, thereby achieving the purpose of treating scale.

[0026] During the operation of the equipment, the temperature of the steam in the water jetting and exhaust device body 1 increases due to the mixing air intake pipe 3. At this time, the cooling fan 15 is started, and the heat of the water jetting and exhaust device body 1 is dissipated on the outside. At the same time, the heat of the water jetting and exhaust device body 1 is evenly dissipated into the cavity formed between the protective cover 13 and the water jetting and exhaust device body 1 through the conduction of the heat conductive sheet 14. The cooling fan 15 discharges the hot air in the cavity, and at the same time, the heat conductive sheet 14 conducts the heat to the protective cover 13, and dissipates the heat through the outside of the protective cover 13 at the same time, thereby achieving the purpose of improving the heat dissipation capacity of the water jetting and exhaust device body 1.
