Description
The present invention relates to the sub-assembly that splashes of devaporizer.
With air do coolant cools water to bring out with the gravity-flow ventilation wet cooling tower be the example of the devaporizer that the present invention relates to, and The present invention be more particularly directed to cooling tower, sub-assembly especially splashes.Yet be appreciated that although the present invention has in this article only described cooling tower, with regard to devaporizer itself or sub-assembly, applicant's intention is not limited to cooling tower.
The applicant recognizes the sub-assembly of different types on wet cooling tower and the operation principle devaporizer identical with cooling tower.These comprise sub-assembly that the applicant knows as " assembly of thin films ", " drip sub-assembly " and " sub-assembly splashes ".In wet cooling tower, assembly of thin films and drip sub-assembly provide the surface area of the increase that water can flow through, therefore increased the exposed surface area of water to promote its cooling, and the sub-assembly that splashes provides the shock surface of water, be divided into less water droplet by impacting these surfaces, thereby the exposed surface area of increase water is to promote its cooling.
The object of the present invention is to provide a kind of water slug surface that has, the dividing plate of splash sub-assembly and this sub-assembly that splashes of the lower and easy-to-install devaporizer of manufacturing cost.
According to the present invention, a kind of sub-assembly that splashes of devaporizer is provided, comprise a plurality of horizontally disposed dividing plates, this dividing plate comprises by anticorrosive to be made, and the plate with holes of mutual perpendicular separation, this sub-assembly that splashes is characterised in that: this plate with holes is a stretch metal, the width in the hole on it and length range are respectively from 10 millimeters and 30 millimeters to 60 millimeters and 120 millimeters, perpendicular separation between dividing plate can make liquid fall between the adjacent dividing plate and be hit becomes the less shape that drips, thereby increase the exposed surface area of liquid, impel heat from the conversion of liquid or convert liquid to.
Having used " stretch metal " speech in this article, is expression with suitably punching press or cutting and be drawn into the wire netting of mesh of sheetmetal.
The stretch metal plate can be a ferrite corrosion protection steel, and its composition is by weight:
Silicon 0.0-1.0%
Chromium 10.5-15%
Manganese 0.0-5.0%
Carbon 0.05% maximum
Nitrogen 0.03% maximum
Titanium 0.05-0.40%
Nickel 0.0-3.0%
Remaining sum is the impurity of iron and permission.The ferrite coefficient is less than 13 in the component, and this coefficient is calculated by following formula: ferrite coefficient=% chromium+(6 * % silicon)+(8 * % titanium)+(4 * % molybdenum)+(2 * % aluminium)-(2 * % manganese)-(4 * % nickel)-40(% carbon+% nitrogen).Be the convenience of succinct and description aspect, this material back is called " 3Crl2 ".Perhaps, metallic plate can be any other stainless steel, aluminium, red copper or brass.
Each stretch metal plate has a flat surface of splashing.This metallic plate is to make with the lower nonmetallic materials of the coefficient of heat conduction.Main heat exchange in the devaporizer has only directly to be carried out between gas and liquid.Yet, metal and guaranteed that with its coefficient of heat conduction of making the 3Cr12 of the best dividing plate of the present invention heat exchange is not only directly between gas and liquid, and between metal, and carry out between heated metal and the coolant media thereafter than thermal medium (or gas or liquid) and dividing plate.Therefore, can fail heat simultaneously gives the thermal medium of coolant media and metal cold sooner.
The size of stretch metal plate mesopore is determined according to purposes.In addition, between the hole of stretch metal plate the width of bar preferably more greatly so that effective shock surface to be provided.And, the void ratio in the dividing plate hole in the stretch metal plate and size depend on whether the stretch metal plate is used for cross-flow environment, this moment, gas flow was horizontal direction and on a plane basically, it is arranged essentially parallel to the plane that the metallic plate that constitutes the sub-assembly that splashes occupies, and transverse to liquid flow direction, or being used for the adverse current environment, this moment, gas flow was the direction on the plane that occupies of transverse metal plate basically, and relative with the direction of liquid flow.When cross-flow environment, the size of stretch metal plate hole will be enough to liquid is passed through.But when the adverse current environment, the size in hole will be enough to liquid is passed through, thereby overcomes the pressure of upwards being taken out simultaneously through the gas in hole.Same reason, the void ratio of stretch metal plate that is used to the sub-assembly that splashes of the situation of flowing over generally is less than the void ratio of the stretch metal plate of the sub-assembly that splashes that is used for reverse flow conditions.
The size of the shape, particularly hole of stretch metal plate mesopore also depends on the characteristic of the special liquid that devaporizer is used and the state of liquid (being its clean-up performance).Be appreciated that the metallic plate that for example has than aperture is applicable to the water of cleaning, have be applicable to preferably than bar between the hole of the metallic plate of macropore and broad dirty, the water that the impurity ratio is high.
