Abstract
The invention relates to a method for improving the thermal property of a cooling tower packing, which comprises the following steps: uniformly adding powder salt on the surface of a packing flat sheet which is ready to be formed before the last pair of rollers in the process of injection molding polyvinyl chloride into the packing flat sheet, pressing the powder slat into the surface of the sheet during the process of pressing the next pair of the rollers, and leading the powder salt to be uniformly distributed on the upper surface and the lower surface of the packing sheet after molding; and then placing the packing sheet in a clean water tank for standing, dissolving the salt into water and taking out the packing sheet which is a finished product. The method can increase the surface roughness of the packing sheet, change the hydrophilicity of a material, increase the air-water contact specific surface area, lead circulating hot water to be easier to form a water film on the surface of the packing sheet, prolong the downward flowing time of the water film due to the surface roughness, increase the heat exchange time and improve the cooling effect of a cooling tower by changing the surface microstructure of the packing sheet.
Description
Technical field
Patent of the present invention belongs to the cooling tower parts, particularly a kind of method that improves cooling tower packing plain film thermal property.
Background technology
The packing plain film is the place that cooling tower is accomplished heat exchange, and the key of the cooling performance of cooling tower is the packing plain film of cooling tower.The packing plain film has the characteristic of two aspects: the one, and thermal property, the 2nd, aeroperformance.Packing plain film thermal property was determined by the specific area of packing plain film, the time that the hydrophily of filler material contacts with aqueous vapor; The aeroperformance of packing plain film is determined by the out-of-date performance (with the Reynolds number of air-flow, the latus rectum of passage and the relative roughness of passage) of passing through of the air communication that the packing plain film can provide.No matter how present widely used packing plain film shape changes, purpose is nothing but in order to increase the specific area of packing plain film, but has ignored the microstructure on packing plain film surface.
Summary of the invention
Method problem to be solved by this invention is: a kind of method that improves packing plain film thermal property is provided.Change the microstructure on packing plain film surface; Can under the condition that does not reduce packing plain film aeroperformance, improve the filler material hydrophily, improve the packing plain film specific area with increase the time that aqueous vapor contacts; Be intended to effectively improve packing plain film thermal property, reach the purpose that improves the cooling tower cooling performance.
The technical scheme of patent of the present invention is:
A kind of method that improves cooling tower packing plain film thermal property is characterized in that: in polyvinyl chloride (PVC) packing plain film thermo forming process, increase following production technology:
Be processed into by the polyvinyl chloride particles injection moulding in the packing plain film process; Before last one pair roller of process; On the surface of the packing plain film that will form, evenly add the powder salt of particle diameter at 0.05mm～0.005mm; The packing plain film that will form of powder salt is spread equably in the last one pair roller pressing process of process in the surface, and powder salt is pressed into the surface of packing plain film, and the upper and lower surfaces of the packing plain film after the moulding is being uniformly distributed with the powder of salt; The packing plain film that will be uniformly distributed with the powder of salt afterwards again is placed on and leaves standstill 1～3 hour in the clear water reserviors, makes salt soluble in water, and the packing plain film of taking-up is finished product.
Effect of the present invention is:
The present invention provides a kind of method that improves cooling tower packing plain film thermal property; Through changing hydrophilicity, the increase air water contacted specific surface area that packing plain film surface roughness changes material; Making needs the circulating hot water of cooling more to be prone on the packing sheet surface form moisture film, and the increase of surface roughness has also prolonged the time that moisture film flows downward, and has increased the time of heat exchange; And the passage of air-flow in filler formed by moisture film, so the resistance that air communication is crossed does not increase.
The specific embodiment
A kind of method that improves packing plain film thermal property: in polyvinyl chloride (PVC) packing plain film thermo forming process, increase following production technology:
Be processed in packing plain film (or claiming sheet material) process by polyvinyl chloride powder (or particle) injection moulding; Before last one pair roller of process, add the powder salt of particle diameter at 0.05mm～0.005mm; This salt has not and polyvinyl chloride generation chemical reaction and characteristic soluble in water; The salt end is compressed on the surface of sheet material equably, and enters into packing plain film molding procedure with sheet material, and the upper and lower surfaces of the packing plain film after the moulding is being uniformly distributed with the powder of salt.The packing plain film that is being uniformly distributed with the powder of salt afterwards is placed on and leaves standstill 1～3 hour in the clear water reserviors, makes salt soluble in water, and the packing sheet of taking-up is finished product.
Get into the salt retracting device when brine strength reaches certain value and reclaim salt, the water recycling after the salt of recovery and the processing.
