Abstract
A surface evaporative and air cooler-cleaning device belongs to an assisted device of the surface evaporative air cooler, in particular relates to an on-line cleaning device. The device solves the conventional problem of the evaporative air cooler, serious scaling on the surface of the tube and poor effect of cooling. The utility model includes nozzles, water pipes, valves, high flux pumps or high water tanks. The nozzles are positioned evenly on the water pipes, the upper part of which connects the high flux pumps or high water tanks with valves, the nozzles above is arranged above the spray pipe of the surface evaporative air cooler. The utility model scours the tube of the heat exchanger at intervals with water, which requires that the water flow stress and the holding capability should be strong enough to scale off the porridge-like fouling and play the role of on-line cleaning, in order to carry out the goal of maintaining high efficient heat transfer, elongating operating cycle of the surface evaporative air cooler and reducing the operating costs.
Description
Technical field
The utility model belongs to the servicing unit of remover for surface evaporation type air cooling, particularly a kind of online apparatus for eliminating sludge.
Background technology
The remover for surface evaporation type air cooling of patent No. ZL96200559.2 (hereinafter to be referred as evaporation air cooler) is a kind of efficient air cooler, and heat exchanger tube wherein is generally light pipe.Shower water forms moisture film easily on the light pipe surface, helps evaporation, and the wind resistance of light pipe is little, manufacturing is installed simple.Water film evaporation is a phase transition process, and it absorbs a large amount of heat in managing, thereby the temperature of thermal medium in the pipe is reduced significantly.If the water of spray on pipe can evaporate fully, then heat transfer efficiency is the highest.But because of shower water communicates with atmospheric environment, so must contain some salinities and dirt in the shower water.If moisture evaporates fully, then salinity and dirt just constantly in pipe outer wall deposition, form dirt, cause bigger thermal resistance, make remover for surface evaporation type air cooling after operation a period of time heat transfer efficiency descend greatly, even can not normally move.At this moment, must be out of service, air cooler is cleaned specially.The more existing method that tackles incrustation scale as electronic descaling, electromagnetic pulse scale removal and ultrasound wave descaling etc., has incrustation scale growth rate on the tube wall of reducing, and makes the effect of incrustation scale tissue looseness, but still incrustation scale effectively can not be removed.
The utility model content
The utility model provides a kind of water current on-line scale remover for surface evaporation type air cooling device, solves serious, the not good problem of cooling effect of the outer fouling of pipe that conventional remover for surface evaporation type air cooling exists.
Water current on-line scale remover for surface evaporation type air cooling device of the present utility model, it is characterized in that: it comprises shower nozzle, water pipe, water valve, big flow water pump or elevated tank, shower nozzle evenly is set on the water pipe, the upstream of water pipe connects big flow water pump or elevated tank by water valve, and described shower nozzle is positioned at the top of remover for surface evaporation type air cooling shower during installation.
During use,, determine the suitable scale removal water yield, scale removal interval and duration according to thermic load, shower water composition and ambient air situation.Every certain interval of time feeds the tube bank of water heat exchanging and washes away a period of time (being the duration).The shear stress of scale removal current is big, can impel the loose new dirt on the tube wall to peel off; The scale removal current sweep along ability strong, the congee sample incrustation scale that peels off on the tube wall is washed away, play the effect of on-line cleaning, keep the air cooler efficient heat transfer, prolong the air cooler cycle of operation, reduce the purpose of operating cost thereby reach.
The utility model subtracts dirty descaling method and matches with existing, will further reduce the tube wall dirtiness resistance, strengthens the heat transfer of tube bank.
Description of drawings
Fig. 1 user mode schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
Among Fig. 1, expressed online apparatus for eliminating sludge of the present utility model, be positioned at the top of conventional surface evaporation air cooler spray equipment, comprised shower nozzle 1, water pipe 2, water valve 3, current can be supplied with by water pump 4 or jumbo elevated tank 5.Surface evaporation air cooler comprises water tank 6, spray water pump 7, air cooler framework 8, bobbin carriage 9, heat exchanger tube 10, spray header and spray head 11.
The current of big flow of the present utility model can be supplied with by the water pump 4 of big flow, also can be supplied with by jumbo elevated tank 5.When needing current to clean the outer wall dirt of heat exchanger tube 10, water valve 3 is opened.Water pipe 2 and shower nozzle 1 are positioned at the top of spray equipment, in order to avoid influence the distribution of normal shower water.The water pipe caliber can be 65mm, length 8000mm, and 7 shower nozzles evenly distribute.Flushing time is very short, such as every operation 24 hours, washed away 10 minutes, the scale removal current of this big flow of short time sweep along ability strong, the congee sample incrustation scale that peels off on the tube wall is washed away, play the effect of on-line cleaning.
