Description
Technical field
The invention belongs to compressed air removal moisture drying field of purification, particularly a kind of cleaning heat-exchanger rig that is applicable to air-cooled condenser in common cooling driers.
Background technology
Cooling driers is freezing type drier, a kind of compressed-air actuated cool drying equipment, generally formed by refrigeration compressor, condenser, throttling arrangement and evaporimeter (bucket), be arranged on the subordinate of air compressor, Main Function is the moisture of removing in the Compressed Gas that transports of air compressor, makes compressed air obtain dry decontamination.
When compressed air process evaporimeter, airborne moisture is condensed into water droplet by the refrigerant cools in evaporimeter, due to the effect of gravity, these water droplets are dropped in the bottom of evaporimeter, then be guided into electronic drain valve by pipeline, the time setting in advance according to electronic drain valve, the valve opening of electronic drain valve, is emitted on water droplet outdoor together with certain high pressure air.Thereby the pressure-air that ensures to enter in system is the dried and clean air that does not contain or lack moisture content.
For the cooling cycle system that ensures cooling driers normally moves, ensure the normal exchange capability of heat of evaporimeter and cooling effect, the condensation effect of the condenser in cooling cycle system is very important, common cooling driers generally adopts air cooled condenser, structure is that coil pipe is finned, use aerofoil fan that force air is sucked, make air pass the surface of coil pipe fin, thereby the heat of the high pressure, high temperature refrigerant in condenser and the very fast airborne cold skimming over are exchanged mutually, refrigerant gas is condensed into the refrigerant liquid of low-pressure low-temperature, supply with evaporimeter through expenditure and pressure, compressed air is carried out to desiccant dehumidification.Therefore the factor such as environment temperature, condenser surface cleannes has a significant impact the normal operation of cooling driers.
Condenser is in the process of work, the cold and the cold-producing medium that constantly suck in surrounding air carry out heat exchange, around here inevitably can be by airborne floating thing or dust batting suction condenser surface, in the course of time can block the gap between condenser fin, pollute coil pipe fin surface, affect heat transfer effect; General treating method is visual blocked state or according to the compressed air quality of discharging, condenser fin is carried out to manual cleanup, such as adopting the padding of air-conditioning comb combing fin clearance, the surface of condenser coil fin etc. is rinsed in employing with the cleaning agent aqueous solution of the low concentration of suitable pressure.These methods can not be processed the pollution of condenser in time, expend certain manpower and materials, bring impact to the normal operation of cooling driers.
Summary of the invention
The object of the invention is for above existing problems, a kind of cleaning heat-exchanger rig that is applicable to cooling driers air-cooled condenser is provided, this device can effectively utilize the discarded low temperature pure air of air compression system itself, resource reusable edible, and simple and reliable for structure, cost is low, easy to implement.
Technical scheme of the present invention:
For a cleaning heat-exchanger rig for cooling driers air-cooled condenser, comprise oil mist filter, electronic drain valve, spray thrower, water collector and support; Cooling driers evaporimeter drainage duct connects oil mist filter, oil mist filter passes through conduit connecting electronic draining valve again, electronic drain valve is connected with cylindric spray thrower one end by conduit and quick jointing, shut with stifled the screwing of spiral shell buckle closure the other one end of cylindric spray thrower, entirety spray thrower is fixed on cooling driers condenser edge with support, and spray thrower has circular hole or the slotted hole of Φ 2-5mm towards condenser one side; Water collector is the water pond that is embedded in condenser bottom, surrounding projection, and a corner of water pond has the conduit that connects Xia Shui water route.
The material of described spray thrower circular pipe is PVC, ABS or PPR tubing, and diameter is Φ 32mm, and the pitch of holes of spray thrower spray apertures is 20mm; Spray thrower installation site is apart from cooling driers condenser fin end surface 50mm.
Be the flexible pipe of diameter of phi 10mm from evaporimeter to the connecting duct between spray thrower.
Described water collector adopts the preparation of galvanized steel plain sheet material, and discharge outlet caliber is 10 millimeters of Φ.
Operation principle of the present invention:
In air compression system device, the effect of electronic drain valve is that the timing of the moisture in compressed air and greasy dirt is discharged, and ensures compressed-air actuated cleaning, therefore have the function that time opening, timing are closed, and opening time and shut-in time can artificially be set.In the time that electronic drain valve turns to unlatching, the Cryogenic air that contains moisture enters spray thrower, and under the effect of pressure, aqueous vapor sprays the surface to condenser through the aperture of spray thrower, wash away the heat that has purified condenser surface and take away again a part of condenser, play the effect of cooling heat exchange.The remaining water for a long time condenser spray being formed is collected at browser at the bottom of the catchment, then flows into sewer by guide hole, conduit.The operation principle of this device in system and structure are as shown in Figure 1.
Advantage of the present invention is: this apparatus structure is simple and reliable, can utilize existing equipment certain modification to implement for compressed air purification system, and cost is low; Utilize the low-temperature cold water resource originally bleeding off, and can regulate easily according to the refrigerating capacity of cooling driers the opening time of electronic drain valve, freely regulated and controled the time and intensity to the heat exchange of condenser spray; Because the front end at electronic drain valve has installed oil mist filter additional, can effectively avoid the pollution of contained oil gas to condenser in compressed air, simplify the regular maintenance to cooling driers, improve the operating efficiency of cooling driers.
