The utility model is matched with the appropriate blower, so the wind volume can be improved; the utility model can use the tube bundle of the air-cooling device, and the tube bundle of air-cooling device has small sheet number; therefore, the utility model improves the heat transfer coefficient of the inner membranes of tubes, solves the problem that a spray head is easy to block and improves the humidifying effect and the cooling effect.
Description
The utility model relates to the aerial cooler in the plant equipment, and concrete is a kind of condensation that is mainly used in various operating modes such as refinery and petrochemical plant, the high-performance wet air cooler in the cooling system.
Wet air cooler is mainly used in the decompression cat head condensation cooling system of finding time, in decompression overhead condensation cooling system, then need to consume a large amount of recirculated water as if the employing water cooler, the atmospheric and vacuum distillation unit of 2,500,000 tons/year for the treatment of capacities is an example with a year, when 35 ℃ of 32 ℃ of circulating water temperature and cooler outlet temperature requirements, then dry type air cooling action need consume about 1000 tons of recirculated water/time, the wet type action need consume about 1200 tons/time, and because the corrosion of cooler, leak, not only can increase the consumption of recirculated water, water amount of blowdown is increased, particularly old plant modification situation causes the change of underground recirculated water pipe network and the reorganization and expansion of recirculated water field owing to consuming a large amount of recirculated water.Therefore, adopt wet air cooler, particularly to water scarcity, the higher area of circulating water temperature, comparatively favourable, but because present wet air cooler exists some problems to bring adverse effect to application:
1. present vacuum tower head space cooler tube bundle all is SL4.5 * 3 (m) specifications basically, and the blower fan diameter is 2.4m, and air quantity has only 18 * 10
4m
3/ h, the not enough 2m/s of windward side wind speed, (standard wind speed is 2.8m/s) causes the sheet number of selecting wet air cooler for use too much, reduced film heat transfer coefficient in the pipe, and equipment investment is bigger.
2. wet air cooling makes Cryogenic air and tube bank carry out cold and hot exchange, thereby reaches the medium cooling purpose mainly by reducing the environment air humidity after the water high atomisation of spray system ejection.Present widely used wet type air-cooling spraying device atomizing effect is undesirable, and the version of shower nozzle is unreasonable, and the shower nozzle volume is big, complex structure, and nozzle very easily stops up, thereby has lost the practical significance of spray.
3. the big area of wind, the water (atomizing effect is good) of wet air-cooling spraying device ejection is blown away by wind, does not play the effect that reduces ambient air temperature, thereby has increased salt air corrosion.Shortened the service life of equipment, particularly in China south, the coastal area makes cold back effect undesirable owing to have characteristics such as high humidity, wind are big, temperature height, and the wet air cooling outlet temperature of the one-level that has reaches more than 40 ℃, and the refinery that has has to adopt water cooler.
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of high-performance wet type air cooling machine is provided, main purpose is to improve air quantity, can use the less air cooler tube bundle of sheet number, improve the heat transfer coefficient of pipe inner membrance, secondly purpose is to solve the easily blocked problem of shower nozzle, improve the effect of humidifying cooling, purpose is to improve abat-vent once more, make the water smoke that sprays out be not subjected to natural wind influence, prevent solar irradiation, improve the backwater rate.

Described spray equipment is made up of jet pipe and nozzle, this jet pipe is " H " shape that is made of both sides straight water pipe and middle horizontal water tube, water main by the middle part supplies water, suitable at interval distance respectively is equipped with 3 nozzles on the straight water pipe of both sides, go up, in two nozzles be the solid cone shaped nozzle, the lower end nozzle is provided with two branches, the mouth of pipe of this branch is equipped with two kinds of nozzles that can exchange that discharge is different, when one of mouth of pipe of this branch was installed nozzle, another mouth of pipe sealed with pipe plug.
Described abat-vent is made up of framework and baffle plate, this framework is by last, sill, a left side, the hollow frame that right vertical beam and waist longeron constitute, on waist longeron, equidistantly be fixed with some baffle plates, every baffle plate is horizontal rectangular plate shape, there is reverse flanging at its both lateral sides edge, this baffle plate installation site and frame plane are certain downtilt angles and the flow direction of air intake are tilted to and enter chamber, each baffle plate installing space is suitable, makes the flanging of adjacent two baffle plates the cover part of vertical frame direction be arranged and stop that air intake can not vertically enter the chamber that cooling tube bundle is housed
The utility model has following actively useful effect:
1. optimize the blower fan design, satisfy the high air quantity of structural requirement, the requirement of low noise, the tube bank speed of facining the wind is reached more than the 2.8m/s, improved finned tube outer air film heat transfer coefficient, simultaneously prolongation consumable accessory service life, reduced equipment investment.
2. optimization nozzle layout of sprinkler is used the solid cone shaped spray nozzle, improves atomization, and simple in structure, is difficult for stopping up, and has solved the problem of shower nozzle congestion affects cooling-down effect more completely.
3. use simple in structure, cost is low, and does not influence the abat-vent of air quantity, can make the water smoke of spray ejection not influenced by natural wind, prevents solar irradiation, the recycle-water rate also can be improved accordingly.
4. optimization blower fan design of the present utility model, optimization nozzle layout of sprinkler are optimized the abat-vent design, also can be applied to the wet type air cooling device of other types.
5. adopt the high-performance wet air cooler that old device is transformed, can reduce owing to the employing water cooler, and will consume a large amount of recirculated waters, therefore the quantities of the reorganization and expansion of the change of the underground recirculated water pipe network that causes and recirculated water field.
