[0001] The invention relates to the technical field of spray heat exchange, in particular to a drip-type high-efficiency generator. Background Art

[0002] With the current increase in the area of ​​centralized heating and the improvement of urban environment, the heating method of long-distance transmission of high-temperature water is now mostly used. The absorption type large temperature difference unit makes the utilization rate of high-temperature water in one network as high as 70%. Conventional generators all use spraying to carry out heat exchange of the solution.

[0003] Some existing spray generators use a spray pipe installed on the upper end of the generator, and a nozzle larger than φ1.5 is installed on the spray pipe to spray the solution onto the heat exchange tube of the generator. This spraying method requires a pressure head of more than 5 meters to be formed in the spray pipe to achieve the best spraying effect, resulting in a high head and high power of the solution pump. In this spraying method, the solution flow rate is too fast and forms a scouring state with the heat exchange tube, which easily causes part of the solution to fail to exchange heat better and be lost in vain. Summary of the invention

[0006] By adopting the above technical scheme, the first-level distribution pipe divides the solution entering the generator into multiple sections longitudinally, so that the amount of solution in each section is approximately equal and flows into the second-level liquid distribution tank. The second-level liquid distribution tank then evenly distributes the solution to the third-level liquid distribution tank. A plurality of third liquid outlet holes are evenly and densely distributed on both sides of the third-level liquid distribution tank, and then a rack is used to drain the solution to the center of each heat exchange tube, so that the solution flows naturally along the tube wall at the top of the heat exchange tube to the bottom and drips into the top of the lower row of heat exchange tubes, so that the solution can fully exchange heat and evaporate, and the heat exchange effect requirements can be fully met under the premise of a small flow rate.

[0013] Preferably, each of the racks is provided with a plurality of U-shaped holes, each of the third liquid outlets is connected with the corresponding U-shaped holes, the tooth tip of each rack faces downward, the height of the tooth tip in each rack is lower than the height of the three-stage liquid distribution trough, and each of the U-shaped holes is located on the same center line as the tooth tip of the corresponding rack; a plurality of heat exchange tubes are fixedly connected to the interior of the generator, and the racks are respectively located above the corresponding heat exchange tubes.

The first-stage distribution pipe 210 divides the solution entering the generator 100 into multiple sections longitudinally, so that the amount of solution in each section is approximately equal and flows into the second-stage liquid distribution tank 220. The second-stage liquid distribution tank 220 then evenly distributes the solution to the third-stage liquid distribution tank 230. A plurality of third liquid outlet holes are evenly and densely drilled on both sides of the third-stage liquid distribution tank 230, and then the racks 300 are used to drain the solution to the center of each heat exchange tube, so that the solution flows naturally along the tube wall at the top of the heat exchange tube to the bottom, and drips into the top of the lower row of heat exchange tubes, so that the solution is fully heat exchanged and evaporated, and the heat exchange effect requirement is fully met under the premise of achieving a small flow rate.

[0024] Conventional generators 100 all use a spraying method to perform heat exchange of the solution. Compared with the spraying generator 100, the dripping generator 100 uses a uniform spraying device with high efficiency and low power consumption, which increases the efficiency of the generator 100 by about 10%, increases the utilization rate of high-temperature water to 75%~80%, and reduces the electric power by about 1KW per hour.

[0025] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 The three primary distribution pipes 210 all include a liquid inlet pipe 211, and the solution enters the three primary distribution pipes 210. The flow rate of the solution in the three primary distribution pipes 210 is lower than the flow rate in the spray pipe 200. The solution is divided into multiple sections in the longitudinal direction, and approximately equal amounts of solution flow out from the first liquid outlet holes 212 respectively. The flow rate out of the three primary distribution pipes 210 is less than the flow rate out of the spray pipe 200. A plurality of linearly arranged first liquid outlet holes 212 are provided at the bottom of the three liquid inlet pipes 211, and the first liquid outlet holes 212 are respectively connected to the corresponding second liquid inlet holes.

[0026] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The tops of the three secondary liquid distribution troughs 220 are fixedly connected to the bottom of each primary distribution pipe 210, and the solution enters the corresponding secondary liquid distribution trough 220 from the second liquid inlet hole. The flow rate of the solution in the secondary liquid distribution trough 220 is lower than the flow rate of the solution in the primary distribution pipe 210, and each secondary liquid distribution trough 220 is perpendicular to the primary distribution pipe 210 and on the same horizontal plane.

[0027] The top and bottom of the three secondary liquid distribution troughs 220 are respectively provided with a plurality of linearly arranged second liquid inlet holes and a plurality of linearly arranged second liquid outlet holes 221. Each first liquid outlet hole 212 is arranged along the same vertical line with the corresponding second liquid inlet hole. Approximately equal amounts of solution flow out from the second liquid outlet holes 221 respectively. The flow rate out of the secondary liquid distribution trough 220 is lower than the flow rate out of the primary distribution pipe 210.

[0028] The top of each tertiary liquid distribution trough 230 is fixedly connected to the bottom of each secondary liquid distribution trough 220, each secondary liquid distribution trough 220 is perpendicular to the tertiary liquid distribution trough 230 on the same horizontal plane, and each primary distribution pipe 210 is parallel to the tertiary liquid distribution trough 230 on the same vertical plane. The secondary liquid distribution trough 220 then evenly distributes the solution into the tertiary liquid distribution trough 230, and the solution enters the tertiary liquid distribution trough 230 from the third liquid inlet 231, and approximately equal amounts of solution flow out from the third liquid outlet 232 on both sides, and are then drained by the rack 300.

[0029] Reference Figure 2 , Figure 5 , Figure 8 A plurality of third liquid inlets 231 are provided on the top of each three-stage liquid distribution trough 230, and each third liquid inlet 231 is connected to the corresponding second liquid outlet hole 221. A plurality of third liquid outlets 232 are provided on both sides of each three-stage liquid distribution trough 230, and each third liquid inlet 231 is arranged along the same vertical line with the corresponding second liquid outlet hole 221. The flow rate and flow rate in the three-stage liquid distribution trough 230 are lower than the flow rate and flow rate in the two-stage liquid distribution trough 220.

[0030] Reference Figure 2 , Figure 8 A plurality of U-shaped holes 310 are provided inside each rack 300, and each third liquid outlet 232 is connected to the corresponding U-shaped hole 310. The solution flows out from the inside of the third liquid outlet 232 and then flows to the U-shaped hole 310 of the rack 300. The U-shaped hole 310 guides the solution to flow to the tooth tip, and then flows from the tooth tip to the corresponding heat exchange tube. The tooth tip of each rack 300 faces downward, so that the solution can drip naturally. The height of the tooth tip in each rack 300 is lower than the height of the three-stage liquid distribution tank 230, and each U-shaped hole 310 is located on the same center line as the tooth tip of the corresponding rack 300.

[0031] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , the diameter of the first liquid outlet 212 is d1, the diameter of the second liquid outlet 221 is d2, the diameter of the third liquid outlet 232 is d3, and the width of the U-shaped hole 310 is d4, d1>d2>d3>d4, the diameters of the first liquid outlet 212, the second liquid outlet 221, the third liquid outlet 232, and the U-shaped hole 310 are gradually reduced, thereby reducing the flow rate and flow rate of the liquid outlet. Compared with the spray generator 100, the solution flow rate is reduced by about 1 / 3, so that the solution pump can choose a lower standard head and flow rate, and the power can be reduced by 1KW / h; The height of the first-stage distribution pipe 210 is the same as that of the second-stage liquid distribution trough 220. The height of the third-stage liquid distribution trough 230 is half of the height of the first-stage distribution pipe 210.

[0032] Reference Figure 1 , Figure 8 A plurality of heat exchange tubes are fixedly connected inside the generator 100, and the racks 300 are respectively located above the corresponding heat exchange tubes. The solution in the generator 100 is fully heated, and the amount of steam formed by the water in the solution increases, so that the concentration of the solution also increases. The generator 100 has greater energy storage and stronger water absorption during the lower-level absorption, resulting in an increase in the utilization rate of the primary heat source by 5% to 10%.

[0033] Reference Figure 1 , Figure 2 The angle of the tooth tip of the rack 300 is 57°. A rectangular body is provided at both ends of the rack 300. The solution is automatically drained by the tooth tips of the rack 300. The solution at both ends of the rack 300 can flow down from the corner ends of the rectangular body. At the same time, the rectangular body part of the rack 300 at one end of the showerhead protects the U-shaped hole 310 and the tooth tip. During transportation, multiple racks 300 can be transported by bundling the rectangular bodies. During installation, it can also be known through the rectangular body whether the rack 300 is aligned with the three-stage liquid distribution tank 230, and large deformation of the rack 300 during installation can be avoided.

[0034] The implementation principle of a drip-type high-efficiency generator is as follows: 1. The first-stage distribution pipe 210, the second-stage liquid distribution tank 220, and the third-stage liquid distribution tank 230 flow by gravity. The solution only needs to be lifted to the top of the generator 100, and the solution can flow down naturally, so that the solution pump head of the drip generator 100 is more than 5 meters lower than that of the spray generator 100. Compared with the spray generator, the drip solution volume reduces the flow rate and the solution flow rate is also reduced by about 1 / 3. When the solution pump of the generator 100 is selected, the power can also be reduced by 1KW / h; 2. The solution in the generator 100 is fully heated, and the amount of steam formed by the water in the solution increases, so that the concentration of the solution also increases. The generator 100 has greater energy storage and stronger water absorption in the next stage, resulting in an increase in the utilization rate of the primary heat source by 5% to 10%.
