Description
Technical Field
The invention relates to a lithium bromide water chilling unit, in particular to a high-temperature generator for a semi-falling film type lithium bromide water chilling unit and a working method thereof.
Background
A double-effect steam and hot water type lithium bromide absorption water chilling unit adopts steam or high-temperature hot water as a heat source, and a lithium bromide solution is concentrated by a high-temperature generator in a vacuum environment to generate steam. And (4) allowing the water vapor to enter a low-temperature generator to serve as a heat source, and concentrating the lithium bromide solution for the second time. Finally, the concentrated solution generated by the high-temperature generator and the low-temperature generator is used as an absorbent, and the generated water vapor is condensed and used as a refrigerant to prepare cold water for air conditioning and other purposes.
As shown in fig. 1: the working principle of the high-temperature generator is as follows: the lithium bromide dilute solution in the cylinder exchanges heat with a heat source in the heat exchange pipe to generate steam, the dilute solution becomes concentrated solution, the steam enters the low-temperature generator to exchange heat, the concentrated solution enters the absorber to be diluted, and then flows back to the high-temperature generator through the dilute solution pipeline.
The heat exchange tubes of the high temperature generator are generally completely immersed in a lithium bromide solution, and are called an immersion type or flooded type high temperature generator. Because the immersion type or flooded type high-temperature generator has a simple structure, the heat exchange tube can be ensured to contact with solution for heat exchange, but the following defects exist: (1) more lithium bromide solution is needed, the resource requirement is high, and the cost is high; (2) more solution needs more heat sources and time to reach the working temperature at the initial starting-up stage; when the cooling is stopped, the cooling tower needs to be started for a long time to assist in cooling, and the machine can be safely stopped; (3) the pressure formed by the solution above the heat exchange tube prevents the solution from boiling, reduces the boiling efficiency, and improves the temperature requirement on a heat source, thereby reducing the output of a unit and the energy efficiency.
If the lithium bromide solution is reduced, the solution uniformly falls on the heat exchange tubes and gradually drops to the heat exchange tube at the lowest row along the heat exchange tube at the upper row, the defect generated by the flooded generator can be overcome, however, the uniformity is poor due to the randomness of the dropping liquid generated in the process of the liquid drops from the heat exchange tube at the upper row to the heat exchange tube at the lower row, and particularly, the heat exchange efficiency is influenced due to the serious uneven liquid distribution of the heat exchange tubes at the bottom. Therefore, the present invention is directed to overcoming the above-mentioned drawbacks of the flooded generator and avoiding the poor heat exchange caused by the non-uniformity of the drop falling process.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide the high-temperature generator for the semi-falling film type lithium bromide water chilling unit, which has the advantages of low cost, uniform heating of the bottom heat exchange tube and high heat exchange efficiency, and the working method thereof.
The technical scheme of the invention is as follows:
a high-temperature generator for a semi-falling film type lithium bromide water chilling unit comprises a cylinder body, wherein a plurality of rows of heat exchange tube bundles are arranged in the cylinder body along the length direction of the cylinder body; a liquid distributor with holes is arranged above the heat exchange tube bundles, and at least one row of heat exchange tube bundles positioned at the bottom are soaked in the solution.
The scheme has the following advantages: (1) by arranging the liquid distributor, after the dilute solution enters the barrel, the dilute solution is firstly distributed by the liquid distributor and then uniformly dropped on the heat exchange tube through the holes, so that on one hand, less lithium bromide solution is needed, the resource requirement is less, and the cost is reduced; less solution needs less heat source and time at the initial stage of starting up, and the working temperature can be reached; when the cooling is stopped, a cooling tower needs to be started in a short time to assist in cooling, and the machine is quickly and safely stopped; on the other hand, the pressure formed by the solution is not arranged above the heat exchange tube, the solution is boiled without obstruction, the boiling efficiency is improved, the output of a unit is further improved, the temperature requirement on a heat source is reduced, and the energy efficiency and the heat source utilization rate are improved; (2) through soaking at least one row of heat exchanger tube bank with the bottom in solution, can avoid the randomness and the inhomogeneity of liquid drop whereabouts process, can guarantee through the formula heat transfer mode of immersing that the heat exchanger tube bank of bottom is heated evenly, improve heat exchange efficiency greatly. The invention overcomes the defects generated by the existing flooded generator, ensures that the bottom heat exchange tube is uniformly heated and improves the heat exchange efficiency.
Furthermore, the holes on the liquid distributor are uniformly distributed, so that the solution is firstly distributed by the liquid distributor and passes through the holes to exchange heat with the heat exchange tube bundle. Through arranging a plurality of even holes, can make solution cloth liquid even, evenly drip promptly to the heat exchange tube bank on, improve heat exchange efficiency.
Further, N rows of heat exchange tube bundles are arranged in the cylinder body up and down, the number of rows of the heat exchange tube bundles soaked in the solution is less than N/2, and an immersion type heat exchange structure is formed, wherein N is more than or equal to 3; preferably, the number of rows of heat exchange tube bundles soaked in the solution is less than N/2. Because the liquid drop from last down drips, the heat exchange tube position leans on the back more, and the randomness of dropping liquid just is big more to lead to the homogeneity variation, especially this kind of phenomenon appears more easily more the row number of heat exchange tube bank, consequently, this invention sets up the heat exchange tube bank selection behind the position and adopts the formula of immersing heat transfer structure, thereby improves heat exchange efficiency greatly.
Further, 1-20 rows of heat exchange tube bundles at the bottom of the cylinder body are soaked in the solution. The number of rows of heat exchange tube bundles needing to be soaked at the bottom can be determined according to the number of the heat exchange tube bundles arranged up and down, for example, the more the rows are, the more the heat exchange tube bundles are soaked, so that the heat exchange efficiency is ensured, and preferably, the heat exchange tube bundle with the bottom of 3-10 rows is soaked in a lithium bromide solution.
Further, the diameter of the hole is 0.2-10 mm, preferably 1-3 mm; the center distance of the holes is 10-100 mm, preferably 20-50 mm. If the pore diameter is too small, the liquid distribution flow is difficult to achieve, and the liquid is easily blocked by dregs in the liquid; too large aperture can cause too much liquid loss in the liquid distributor at the front section and liquid shortage at the rear section, thus causing uneven liquid distribution; especially, when the load of the unit is small, the liquid distribution amount is small, and the situation is more serious.
Further, the liquid distributor is provided with a steam channel for passing steam. Because the solution can produce steam after being heated and boiled, the steam that can make the production smoothly exports from the liquid distributor through setting up the steam passageway.
Furthermore, the liquid distributor is a liquid distribution disc with holes, and gaps are arranged between the liquid distribution disc and the periphery of the cylinder body and are used as the steam channel; or the liquid distribution disc is provided with the steam channel with the solution enclosure; or the liquid distributor comprises a plurality of liquid distributing pipes which are arranged at intervals, the holes are arranged on the liquid distributing pipes, and the space between the liquid distributing pipes forms the steam channel.
Furthermore, the outer walls of the heat exchange tubes of the heat exchange tube bundle are subjected to roughening treatment, the roughness is 0.5-100 microns, the outer walls of the two ends of each heat exchange tube are not subjected to roughening treatment, and the light tube sections are reserved. The surface of the heat exchange pipe is roughened, so that the adhesive force to liquid can be improved, and the thickness of a liquid film can be improved; the capillary phenomenon of roughening increases the diffusion distance of the droplets; the roughened surface can also improve the surface area of the heat exchange tube and increase the heat exchange efficiency. However, excessive roughness causes the thickness of the liquid adsorbed on the surface to be too large, and the flow and heat exchange are affected. The heat exchange tube adopts a special process, and the outer wall of the tube is subjected to roughening treatment, including but not limited to shot blasting, sand blasting, shot blasting, chemical corrosion and mechanical processing; and because the two ends of the heat exchange tube need tube expansion, the light tube section is reserved. Preferably, the roughness is 1 to 50 μm, and more preferably 2 to 10 μm.
Further, the length of the light pipe section is 10-150 mm, preferably 15-80 mm, and further preferably 20-60 mm.
The invention relates to a working method of a high-temperature generator for a semi-falling film type lithium bromide water chilling unit, which comprises the following steps: the dilute solution enters the cylinder body, is distributed by the liquid distributor, uniformly drops on the heat exchange tube bundles through the holes, exchanges heat with a heat source in the heat exchange tubes, is heated to boil, and then enters the next row of heat exchange tube bundles for further boiling and concentration; the heat exchange tube bundle at the bottom is soaked into the solution, and the solution at the part is directly boiled and concentrated to reach the required concentration and then flows out of the cylinder.
The invention has the beneficial effects that: on one hand, by arranging the liquid distributor, less lithium bromide solution is needed, the resource requirement is less, and the cost is reduced; less solution needs less heat source and time at the initial stage of starting up, and the working temperature can be reached; when the cooling is stopped, a cooling tower needs to be started in a short time to assist in cooling, and the machine is quickly and safely stopped; moreover, the pressure formed by the solution is not arranged above the heat exchange tube, the solution is boiled without obstruction, the boiling efficiency is improved, the output of a unit is further improved, the temperature requirement on a heat source is reduced, and the energy efficiency and the heat source utilization rate are improved; on the other hand, through soaking at least one row of heat exchanger tube bank with the bottom in solution, can avoid the randomness and the inhomogeneity of liquid drop whereabouts process, can guarantee through immersive heat transfer mode that the heat exchanger tube bank of bottom is heated evenly, improves heat exchange efficiency greatly. The invention overcomes the defects generated by the existing flooded generator, ensures that the bottom heat exchange tube is uniformly heated and improves the heat exchange efficiency.
