Description

Remover for surface evaporation type air cooling

The utility model relates to a kind of remover for surface evaporation type air cooling that is used for condensation, process for cooling thermal medium.Be applicable to condensation, the cooling of the various low potential temperature processing medium of industries such as oil refining, chemical industry, electric power, metallurgy.

At present, China's oil-refining chemical industry air cooler commonly used has dry type air cooling and wet type air cooling.Its heat-transfer mechanism: mainly conduct heat outward by expansion pipe external surface area enhanced tube, take away heat by the air temperature rise, though the wet type air cooling also has evaporation, but because its structural limitations, the film forming on spray property and finned tube surface is all relatively poor, and the heat of taking away by evaporation only accounts for the very little part of whole thermic loads.Main thermic load is still finished by the temperature rise of air.Existing wet type air cooling exists that nozzle easily stops up, spray property is poor, and the problems such as bad processing of leaking make the use of air cooler be subjected to certain restriction.

Recently, it is better to have made out surface evaporation cooler effect abroad.Its structure is seen Fig. 3, establishes centrifugal blower 1 above the water tank 10, and the centrifugal blower side is established air intake, the coiled pipe 4 that circulates for processing medium above the centrifugal blower, establishing the shower 3 of band shower nozzle on the top of coiled pipe, establish demister 2 above the shower, is air outlet slit above the demister; Water circulating pump 6 is sent the water of 10 li in water tank into shower and is sprayed through shower nozzle; Centrifugal blower is discharged air through coiled pipe, shower, demister and through air outlet slit.Because blower fan limited location system, air quantity is little, and this cooler is difficult for maximizing in addition, and transportation and maintenance be difficulty also.

The purpose of this utility model is to design and a kind ofly blower fan is arranged on upper end, bottom is provided with the remover for surface evaporation type air cooling that air suction inlet and light pipe tube bank two ends are provided with threaded stifled rectangular pipe box for overcoming above-mentioned weak point, strengthened the outer heat transfer of pipe, the processing medium outlet temperature can be as cold as near environment wet-bulb temperature, good cooling results.

The utility model content, the blower fan of remover for surface evaporation type air cooling is located at the top of this air cooler; Establish air suction inlet in the bottom of this air cooler and above being positioned at water tank, establish water-collecting tray on the water tank; The shower front end of the spray equipment of being made up of shower, nozzle, circulating pump is established the joint door of regulating flow; Rectangular pipe box is established at the two ends of light pipe tube bank, be provided with the tube bank that processing medium flows between two rectangular pipe box, the two ends of each pipe of tube bank are loaded on respectively on the madial wall of two rectangular pipe box, the lateral wall of rectangular pipe box is provided with and can screwed plug be installed in the screwed hole by blocking the screwed hole of the plug of restraining pipe.

The pipe of light pipe tube bank is a galvanized pipe.

The utility model advantage, remover for surface evaporation type air cooling are split combination structure, manufacturing, transportation and easy to maintenance; The blower fan that is arranged on this air cooler top adopts large-scale induced air type axial flow blower, and the air cooler bottom is provided with air intake, and the evaporation, the enhanced tube that have quickened light pipe tube bank outer surface moisture film conduct heat outward, have improved the efficient of air cooler, have reduced energy consumption; During the tube leak of light pipe tube bank, take off the screwed plug on the rectangular pipe box, the pipe that leaks is blocked, can continue production, it is rapid, easy to maintenance to fix a breakdown; Compare with used wet air cooler, under the same conditions, can save one-time investment 20% for every, save energy consumption 38%, save Operation and Maintenance expense 25%, floor space has also saved 1/2nd.

Description of drawings:

Fig. 1 is the utility model schematic diagram;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is existing surface evaporation cooler schematic diagram.

Below in conjunction with the preferred embodiment of description of drawings the utility model, remover for surface evaporation type air cooling is made up of blower fan 1, demister 2, spray equipment 3, light pipe tube bank 4, framework 5, water tank 10 and circulating pump 6 major parts; Blower fan 1 adopts induced air type, big flow, low-head axial flow blower and is arranged on the remover for surface evaporation type air cooling top; Above the bottom of frame 5 is positioned at water tank 10, establish air intake 11, establish water-collecting tray 16 on the water tank, prevent that shower water from spilling; The shower front end of the spray equipment of being made up of shower 14, nozzle 13, circulating pump 6 is established the joint door 17 of regulating flow, can regulate according to water requirement; The two ends of light pipe tube bank 4 are made as rectangular pipe box, set up tube bank between two rectangular pipe box, and the pipe 18 of tube bank is connected with expanding joint method with the madial wall of rectangular pipe box, and this pipe is through zinc-plated processing, and the lateral wall of rectangular pipe box is equipped with screwed plug 19; Take off screwed plug, can block the pipe of leakage, continue to produce; Processing medium inlet 15 is established in the end of demister 2, and processing medium outlet 12 is established in the end of light pipe tube bank 4, and remover for surface evaporation type air cooling upper end (the blower fan place promptly is installed) is an air outlet slit; Water tank 10 is provided with overfall 7, water supplement port 8 and sewage draining exit 9; Circulating pump is delivered to the shower of the light pipe tube bank top of horizontal positioned to the recirculated cooling water in the water tank, through nozzle cool water shower to the light pipe tube bank, form continuous moisture film at outer tube surface; Blower fan sucks air by the air intake of bottom simultaneously, and air is moved from bottom to top, and the horizontal light pipe of plunderring is restrained, and the moisture film of outer tube surface evaporates rapidly, has strengthened conducting heat outside the pipe.In the evaporative air-cooling process, processing medium is walked bottom horizontal flow sheet in the pipe, and empty G﹠W is walked outside the pipe, and air flows from bottom to top, and water flows from top to down, and water, air and processing medium are for intersecting cross-flow, and water and air are adverse current, augmentation of heat transfer.
