The cooling tower transformation front and back Contrast on effect of the utility model:
Structure before transformation:
Using the S type filler plate of square counter flow type, material is MODIFIED PP, high temperature resistant≤75 DEG C, and high temperature resistance is poor.Tributary
Pipe is consistent with the caliber of nozzle, causes initial water pressure big, and shower is strong, but subsequent hydraulic pressure is low, and shower is powerless；Tributary
Pipe is connected to nozzle straight line and sprays downwards, and water droplet falls fastly, and atomizing effect is generally undesirable, and heat exchange efficiency is not high；Flow: Q=
1000 m3/h * 1, blower motor power 30KW, blower diameter 4700mm；Air quantity is 556000m3/h, and blade material is glass
Glass steel, cooling tower separate unit key dimension are 7800*8000mm, are taken up a large area.
There are problems:
The cooling water channel belongs to spray form and is allowed to sufficiently exchange heat as mesh to reduce dripping flow rate by S type filler plate
, but since actual condition difference flushing cinder coolant-temperature gage higher especially summer is up to 90 DEG C -95 DEG C, and wherein contain a large amount of glass
Silk fiber and tiny mineral slag particle easily cause S type filler plate overheating deforming or the blocking of PP material, and water flow is unsmooth, influences to dissipate
Heat, cooling effect are poor.Inflow temperature t1=80 DEG C, leaving water temperature t2=65 DEG C, 15 DEG C of cooling effects of the temperature difference are low.
Improved structure type:
Using the glass fibre reinforced plastics cooling tower of former square counter flow type and single air duct and water distribution main line, it is laid out pipe network form again,
Interplanar spacing 500mmx1000mm misplaces alternate to spray, and using the spray head of carbon steel material, spray orifice Φ 25mm will not be blocked, and
And water collector is set without cooling tower top.Water distribution system: being shell and tube to spray, aerosol type.
Improvement effect:
Because belonging to Sprayable, the use of S type filler plate is eliminated, high temperature is not afraid of and prevents blocking, deformation failure.It is other
Structure type and mating hydraulic pressure, air quantity are constant；- 95 DEG C of summer inflow temperature t1=90 DEG C, -53 DEG C of leaving water temperature t2=46 DEG C；
- 85 DEG C of winter inflow temperature t1=75 DEG C, -46 DEG C of leaving water temperature t2=36 DEG C, cooling effect is good.
