Description
Technical field
The present invention relates to Blast Furnace Iron-making Production Technology field, more particularly, to a kind of employing soft water airtight circulating cooling system
Shell-and-plate blast furnace evaporative air-cooling system and its plate dirt processing method.
Background technology
Evaporation air cooler be mainly characterized by using outside the evaporation enhanced tube of outside tube water film conduct heat, its work process be with system
Water circulating pump in system by spraying cooling water be transported to positioned at horizontal positioned light pipe tube bank top spray water dispenser, by point
Cooling water is sprayed downwards tube surface by orchestration, makes tube outer surface form the thin water film of continuous uniform；Simultaneously will with blower fan
Air sucks window from equipment lower air and sucks, and makes the bottom-up flowing of air, the horizontal light pipe tube bank plunderring horizontal positioned.Now
The pipe unofficial biography evanescence of heat of heat-transfer pipe relies on outside the sensible heat transfer between moisture film and air stream, and the rapid evaporation of tube outer surface moisture film absorbs
Substantial amounts of heat, enhances the outer heat transfer of pipe.
Because water has the higher latent heat of vaporization (the water latent heat of vaporization at one atm is 570Kcal/Kg) therefore
The evaporation of outside tube water film greatly enhances the outer heat transfer of pipe, so that outfit of equipment heat transfer efficiency is significantly improved.Tube outer surface moisture film
Evaporation make air pass through light pipe tube bank after humidity increase and close to saturation, blower fan is usually overhead type, by saturated moist air from
Extract and pass through the water deflector above spray water dispenser in tube bank out, remove the water droplet carried secretly in saturated moist air
Afterwards, from equipment top, fan outlet enters air, because blower fan is drawn up air positioned at its upper side, thus under blower fan
Portion space forms negative pressure region, accelerates the evaporation of tube outer surface moisture film, is conducive to heat transfer, evaporative type cooler outside enhanced tube
In, processing medium walks bottom horizontal flow sheet in pipe, and empty gas and water is walked outside pipe, and air flows from bottom to top, and shower water then flows from top to bottom
Dynamic, water, air and processing medium are to intersect cross-flow, and water is adverse current with air, although so enhancing from flow arrangement
Heat and mass transfer process, but also bring the technology that the easy corrosion of blower fan and motor are led to service life not grown by the long-term erosion of steam
Problem.
At present as a kind of evaporative type cooler of Patent No. 02255480.7, by the water in water tank is extracted into spray dress
Put, and water is sprayed on heat-exchanging tube bundle, by heat-exchanging tube bundle surface evaporation of water, and then reach the effect of heat transfer, and
In the past chiller was compared, this cooler have take up an area that little, efficiency of transmission is high, cost of investment is low, that Municipal Sewage for Circulating is few is excellent
Point, but due to the shell of this cooler is fixing, shell does not have openable door, therefore, continuous with cooler
Use, heat-exchanging tube bundle surface easily forms incrustation scale it is impossible to timely clean, the efficiency of impact heat transfer.
China Patent Publication No.：202177322U, discloses a kind of plate-type evaporative cooler, including the water located at bottom
Case, be located at water tank above housing, located at the air intake on housing, in housing and be located at air intake above heat exchange
Device, the spray equipment above heat-exchanger rig, by spray upper hose be connected with spray equipment water circulating pump, located at spray
Water collection device above shower device, the chiller above water collection device, described spray equipment includes complex root spray arm, often
Root spray arm is provided with a plurality of water-locators, and described heat-exchanger rig is the heat exchanger plates bundle that plural block heat exchanger plates compacting is formed, and changes
Formed between hot plate can the passage that passes through of heat supply process medium, described heat exchanger plates bundle two ends are provided with the thermal process with above-mentioned channel connection
Medium entrance and outlet.This cooler heat-exchanger rig takes up room, and little, transmission efficiency is high, and this cooler is also preferably saved simultaneously
Water resource.But this utility model equally exists blower motor service life, and length and plate dirt process halfway problem.
