Abstract
The utility model discloses a composite tube bundle heat exchange device for an air cooler. The device is structurally characterized in that M*N steam condensation tubes form an array, wherein a raw of steam extraction tubes is arranged in the (N+1)th column; lower ports of the steam condensation tubes and the steam extraction tubes are positioned in lower headers to form composite tube bundle units; inlets of the steam condensation tubes of each composite tube bundle unit are gathered in an upper header which is connected with a steam trunk main through a branch pipe; the lower headers of all the composite tube bundle units are connected and converged into a water return tank through the branch pipes; and the steam extraction pipes of all the composite tube bundle units are converged to and communicated with a main pipe which is connected to a vacuum pump. The composite tube bundle units form a lambdoidal structure, and are fixedly arranged through a bracket. The device has the characteristics that a set of fan system special for steam extraction tube bundles of composite tube bundles is not required to be additionally arranged, and a system cannot be stopped when a certain group of fans of the system fail. Land and space areas occupied by an air cooling unit adopting a composite tube bundle heat exchange mode can be effectively reduced.
Description
Technical field
The utility model belongs to Thermal Equipment, is specifically related to a kind of combined type tube bank air cooler heat-exchanger rig.
Technical background
The fields such as petrochemical industry and power plant all adopt Air-cooled Condenser (abbreviation Air-cooled Unit) that high temperature fluid is carried out cooling heat transferring mostly at present.Fluid is steam if be cooled, and contains so more on-condensible gas in the vapor stream, and the heat exchange efficiency of heat exchanger is greatly reduced.The structure of heat-exchanging tube bundle is in the general air cooler, several groups of heat-exchanging tube bundles and to connect be a unit, and each unit pipe bundles all will be equipped with a cover blower fan system, in order to provide cooling needed air quantity to the fluid media (medium) in restraining.Arrange separately one or several tube bank unit for getting rid of on-condensible gas in the ratio (calculating according to actual condition) of total tube bank simultaneously, each unit needs respectively to be equipped with blower fan system separately.The defective of this tube bank heat exchange structure is, Air-cooled Unit on-condensible gas when operation is discharged tube bank in case go wrong, especially hinder for some reason and can not move the time, will badly influence the operation of whole Air-cooled Unit when the motor in the blower fan system or reducing gear etc., even cause production system to be stopped transport.In addition also increased the cost of investment of blower fan system equipment.And the tube bank of the combined type of proposition of the present utility model can make this problem obtain the solution of essence.
Summary of the invention
The purpose of this utility model is, proposes a kind of combined type tube bank air cooler heat-exchanger rig, connects row's extraction steam pipe at each combined type tube bank unit steam condensation Guan Jun, when the blower fan system of certain unit Shi Buhui that goes wrong causes system to stop transport.
The technical solution of the utility model is: combined type tube bank air cooler heat-exchanger rig comprises: steam condensation pipe, extraction steam pipe, vavuum pump, backwater tank and Fan Cooling System etc.Form an array by M * N root steam condensation pipe, wherein M is the line number of steam condensation pipe; N is columns, and the N+1 row are provided with row's extraction steam pipe, and the lower port of steam condensation pipe and extraction steam pipe places in the lower collecting box, consists of thus a combined type tube bank unit.The import of each combined type tube bank unit steam condensation pipe concentrates on a upper header, and upper header is connected by the total main of arm and steam; All the lower collecting box of combined type tube bank unit is collected to the backwater tank by the arm connection.All the extraction steam pipe of combined type tube bank unit compiles the house steward of UNICOM to, and this house steward is connected to vavuum pump, combined type is restrained unit composition herringbone structure fix by support.
Principle of the present utility model is: for heat and power system, the exhaust steam of discharging from steam turbine enters the steam condensation pipe that each combined type is restrained the unit by the total main of steam, and steam flows from top to bottom in pipe and condenses.The not condensing body that contains in the steam just is gathered in the low head of steam condensation pipe owing to be difficult to condense.Because the outermost (N+1 row) in each combined type tube bank unit is provided with one and arranges extraction steam pipe, thus these not the condensing body can extract out by vavuum pump from bottom to top along extraction steam pipe.Meanwhile also can be with the related extraction of small part steam in the process of drawing gas, and the extraction steam pipe outer wall studs with fin (enforcing condensation), thus the steam in the extraction steam pipe with very fast condensation, condensate water flows to low head from top to bottom along tube wall and discharges.
The beneficial effect of characteristics of the present utility model and generation is: the tube bank of (1) combined type is integrated steam condensation pipe and extraction steam pipe, so need not join in addition a cover blower fan system for the tube bank unit that draws gas, has reduced manufacturing cost.(2) the power uniformity of each tube bank group blower fan when wherein one group of blower fan system breaks down, only causes the degradation of heat exchange performance of Air-cooled Unit integral body, but can not cause system to stop transport.(3) adopt combined type to restrain the Air-cooled Unit of heat exchange, can effectively reduce the area occupied in land and space.

The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment principle of the present utility model and structure are described further.Need to prove that present embodiment is narrative but not determinate, does not limit the scope that the utility model is protected with this embodiment.
Combined type tube bank air cooler heat-exchanger rig, its architectural feature is: form an array by M * N root steam condensation pipe 1, wherein M is the line number of steam condensation pipe; N is columns, and the N+1 row are provided with row's extraction steam pipe 2, and the lower port of steam condensation pipe and extraction steam pipe places in the lower collecting box 3, consists of thus a combined type tube bank unit.The import of each combined type tube bank unit steam condensation pipe concentrates on a upper header, and upper header is connected by the total main 4 of arm and steam; All the lower collecting box of combined type tube bank unit is collected to backwater tank 5 by the arm connection.All the extraction steam pipe of combined type tube bank unit compiles the house steward of UNICOM to, and this house steward is connected to vavuum pump 6.Combined type is restrained unit composition herringbone structure fixes by support.Every 2-3 is furnished with a cover Fan Cooling System 7 to the combined type tube bank unit of herringbone structure.The steam condensation pipe is the flat tube with fin, or with the pipe of fin.Extraction steam pipe is as the on-condensible gas discharge pipe, and extraction steam pipe is the pipe with fin.
