Description
The present patent application is divisional application, parent application number: 2016109285250；Female case title: a kind of close using soft water
The shell-and-plate blast furnace evaporative air-cooling system and its plate dirt processing method of closed loop cooling system；Parent application day: 2016-10-31.
Technical field
The present invention relates to Blast Furnace Iron-making Production Technology fields more particularly to a kind of shell-and-plate blast furnace evaporative air-cooling system to run
Middle plate dirt processing method.
Background technique
Evaporation air cooler is mainly characterized by conducting heat outside the evaporation enhanced tube using outside tube water film, and the course of work is with being
Spraying cooling water is transported to the spray water dispenser for being located at horizontal positioned light pipe tube bank top by the water circulating pump in system, by dividing
Cooling water is sprayed downwards the thin water film for making tube outer surface form continuous uniform to tube surface by orchestration；It simultaneously will with blower
Air makes the bottom-up flowing of air from the sucking window sucking of equipment lower air, horizontal to plunder horizontal positioned light pipe tube bank.At this time
It is conducted heat in addition to by the sensible heat transfer between moisture film and air stream outside the pipe of heat-transfer pipe, the rapid evaporation of tube outer surface moisture film absorbs
A large amount of heat is enhanced and is conducted heat outside pipe.
Therefore due to the water latent heat of vaporization with higher (latent heat of vaporization of water at one atm is 570Kcal/Kg)
The evaporation of outside tube water film greatly enhances conducts heat outside pipe, significantly improves equipment overall heat transfer efficiency.Tube outer surface moisture film
Evaporation so that air pass through light pipe tube bank after humidity increase and close to saturation, blower is usually overhead type, by saturated moist air from
It extracts and passes through the water deflector being located above spray water dispenser in tube bank out, remove the water droplet carried secretly in saturated moist air
Afterwards, it is discharged into atmosphere from fan outlet at the top of equipment, air is drawn up since blower is located at upper side, thus under blower
Portion space forms negative pressure region, accelerates the evaporation of tube outer surface moisture film, is conducive to conduct heat outside enhanced tube, evaporative type cooler
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 are to intersect cross-flow with processing medium, and water and air are adverse current, although so enhancing from flow arrangement
Heat and mass transfer process, but also bring blower and be easy to corrode and corroded the technology for causing service life not grown for a long time by hot gas with motor
Problem.
At present such as a kind of evaporative type cooler of Patent No. 02255480.7, filled by the way that the water in water tank is extracted into spray
It sets, and water is sprayed on heat-exchanging tube bundle, by the evaporation of heat-exchanging tube bundle surface water, and then achieve the effect that heat transmitting, and
Previous cooling device was compared, the cooler have take up little area, that efficiency of transmission is high, cost of investment is low, Municipal Sewage for Circulating is few is excellent
Point, but due to the shell of the cooler be it is fixed, there is no openable door on shell, it is therefore, continuous with cooler
It uses, heat-exchanging tube bundle surface scale easy to form can not clean in time, influence the efficiency of heat transmitting.
China Patent Publication No.: 202177322U discloses a kind of plate-type evaporative cooler, the water including being set to bottom
Case, the shell above water tank, the air intake on shell, the heat exchange for being set in the housing and being located above air intake
Device, the water circulating pump connecting by spray upper hose with spray equipment, is set to spray at the spray equipment above heat-exchanger rig
Water collection device above shower device, the cooling device above water collection device, the spray equipment include complex root spray branch pipe, often
Root sprays branch pipe and is equipped with a plurality of water distributors, and the heat-exchanger rig is that plural block heat exchanger plates suppress the heat exchanger plates beam to be formed, and changes
Formed between hot plate can the channel that passes through of heat supply process medium, heat exchanger plates beam both ends are equipped with the thermal process being connected to above-mentioned channel
Medium entrance and outlet.The cooler heat-exchanger rig occupies little space, transmission efficiency is high, while the cooler is also preferably saved
Water resource.But the utility model equally exists blower motor service life, and long and plate dirt does not handle halfway problem.
