Problems solved by technology

Through more than ten years of production and sales, the applicant has tracked and analyzed the actual use effect of the existing double-slope water spray filler in the cooling tower of the power plant, listened to the opinions of the users of the power plant, and after repeated analysis and research, the applicant It was found that the cooling surface area of ​​the existing water spray filler can be further increased, there are too many bonding points in the middle, and the height is too large, the ventilation resistance is too large, the ventilation flow rate is too small, the homogenization and distribution of cooling water is not good, and the thickness of the water film Inhomogeneous, the contact between hot water and cooling airflow is not sufficient and uniform, and the best cooling effect cannot be achieved

specific Embodiment approach

[0016] As shown in accompanying drawings 1-4, the cooling tower’s novel double-slant-wave spraying filler has several outer bonding points 1 on its length side 3, and four sets of main cooling bands 2 are arranged on the entire plate surface. , each main cooling band 2 is obliquely distributed and arranged at equal intervals. A wave distance is dislocated and reversed to form a "herringbone"-shaped water film flow channel. There are several inner bonding points 5 between two adjacent groups of main cooling bands 2, and the distance between the inner bonding points 5 is the outer bonding. 2 to 3 times the distance of point 1, 2 times in this example; several secondary retention corrugated grooves 4 with the same interval are added on the main cooling band 2, the cross-sectional shape of which is sinusoidal, and the length of the secondary retention corrugated grooves 4 is equal to The included angle between the sides 3 is 15°, the peak 21 of the main cooling band 2 and the trou...

Abstract

This invention relates to new double-slope wave trickle fillings of a cooling tower, in which two adjacent sets of main cooling wave bands are arranged reversely in stagger with a pitch of waves in between, the distance of the internal binding points is 2-3 times that of the exterior one, a secondary stagnant wave groove is set on the wave band and the cross section is a sine wave, the angle between the stagnant wave groove and the length edge is 15deg, a shunt bank is set between the peak of a main wave band and the valley of the adjacent main wave band to transit smoothly and the highest point of the shunt bank is 4/1-2/1 of the peak.

Description

Technical field: [0001] The invention relates to a water-sprinkling filler, in particular to a water-sprinkling filler for a cooling tower of a power plant. Background technique: [0002] Water spray filler is the key cooling material in the cooling tower. Its main function is to increase the heat dissipation area, extend the air cooling path, and improve the cooling effect of the cooling tower. It is the core component of the cooling tower in the power plant. It is safe for the cooling tower , economical and efficient operation play a decisive role. The plate type of water-sprinkling filler has attracted much attention from electric power design institutes and power plants. In 1994, domestic authoritative research institutions such as the National Water Conservancy and Electric Power Design Institute, Northeast Electric Power Design Institute, East China Electric Power Design Institute and other domestic authoritative research institutions jointly developed double-slope Wav...
