Atomizing propulsion aeration cooling tower multichannel air inlet structure
Technical field
The utility model is to belong to the cycling use of water cooling device to make the field, is the improvement to existing large-scale atomizing propulsion aeration cooling tower air intake passage.Changing original single passage air intake is the multichannel air intake, and the enough outer new wind of tower can be provided for the spray-propelling atomizer of large-scale atomizing propulsion aeration cooling tower middle part like this, simultaneously its required filler can be installed easily.
Background technology
The cooling of recirculated water of carrying under one's arms used heat, major part all adopts the cooling tower technology at present.Except that traditional induced cooling tower, cooling stack, the mid-90 in 20th century, no filler or Packed atomizing propulsion aeration cooling tower no electric fan have appearred.At present, this technology only is applicable in the middle-size and small-size cooling water system.Handling the water yield greater than 1000m
3Can't be suitable fully in the large-scale cooling water system of/h.This is because large-scale atomizing propulsion aeration cooling tower tower body domestic demand is installed tens to up to a hundred spray-propelling atomizers, because the trickle " curtain of rain " between adjacent spray-propelling atomizer produces bigger windage, causing in the tower spray-propelling atomizer in centre position to can not get enough new wind replenishes, make its resh air requirement not reach designing requirement, also needed filler can't be installed below the spray-propelling atomizer in centre position simultaneously.The temperature drop performance that this just has a strong impact on whole tower has limited the utilization of this technology in large cooling column.
Summary of the invention
Do not replenish for the spray-propelling atomizer that overcomes present large-scale atomizing propulsion aeration cooling tower middle part has the outer new wind of enough towers, again required filler can not be installed easily, thereby have a strong impact on the difficult problem of whole tower thermal performance, the special the utility model that proposes.It provides a kind of multichannel air inlet structure, and this structure can solve an above-mentioned difficult problem fully effectively.
The technical scheme that its technical problem that solves the utility model adopts is:
1. in the air inlet below the atomizing propulsion aeration cooling tower drip water plate, the ponding dish with a plurality of three-back-shaped groove shape structures becomes a plurality of air intake passages with space segmentation.The ponding dish of these three-back-shaped groove shape structures by descending, stagger successively from high to low, be supported in the tower below the pairing spray-propelling atomizer the whole pyramidal structure that falls that forms a multilayer with steel frame construction spare.
2. the setting height(from bottom) of each lamination water pond is determined by total intake of its pairing spray-propelling atomizer and required intake velocity.
3. there are how many spray-propelling atomizers to determine the quantity of ponding dish according to middle part in the tower.
4. install downwards on every lamination water pond and receive water pipe, each is received water pipe and directly leads in bottom ponding dish or the cistern.
5. needed filler is installed in every lamination water pond.
The beneficial effects of the utility model are, in large-scale atomizing propulsion aeration cooling tower, the required new wind of each spray-propelling atomizer can both be under the resistance that does not have adjacent spray-propelling atomizer trickle " curtain of rain " in the tower, enter in the tower swimmingly, make each spray-propelling atomizer can both reach design air flow, simultaneously can install needed filler easily, thoroughly solved the difficult problem that present large-scale atomizing propulsion aeration cooling tower ran into: trickle " curtain of rain " resistance that the new wind of the spray-propelling atomizer in centre position replenishes because of adjacent spray-propelling atomizer does not reach design air flow, again required filler can't be installed.

#Six needed additional new wind of spray-propelling atomizer will just can enter by packing layer and one deck or two-layer trickle " curtain of rain ", and trickle " curtain of rain " has bigger resistance to air.In same seat cooling tower, the power output of each spray-propelling atomizer is the same, can't adjust, and this just makes these six spray-propelling atomizers can not get enough air quantity and replenishes, and makes its intrinsic air quantity index not reach requirement.
