Abstract
The invention discloses a fan tower tube cooling device which comprises an air feed unit and an air exhaust unit which are fixed on a tower tube access door. The air feed unit and the air exhaust unit are both connected with an electric control cabinet and a temperature control switch. The temperature control switch controls the starting and stopping of the air feed unit and the air exhaust unit. An air inlet tube of the air feed unit and an air outlet tube of the air exhaust unit both stretch out of the tower tube access door. The fan tower tube cooling device is reasonable in structure and simple to operate, the problem of cooling at the bottom of a fan tower can be greatly eliminated and the operating efficiency of the fan can be improved. The fan tower cooling device satisfies the requirement of long-time normal operations of the fan and the control cabinet while the structure of the fan tower tube remains unchanged.
Description
Technical field
The present invention relates to a kind of sink, particularly a kind of blower fan tower barrel sink that is used under the land hot environment.
Background technique
Because the wind-powered electricity generation industry developed rapidly in recent years, it is concentrated relatively that wind energy resources enriches the area, and the high wind speed area has become rare resource at present.Under the situation that the wind-powered electricity generation exploitation in the abundant area of wind resource has hastened towards saturation at present, the low wind speed and wind electric field exploitation that resource is owed abundant area will welcome the huge market space.Low wind speed wind field has two distinguishing features, and the one, wind speed is between the 6-8 meter per second, and the annual utilization hours number is below 2000 hours; The another one characteristics are that low wind speed wind field is positioned at the high a lot of area of the more northern high wind speed wind field of temperature such as Anhui, Hubei, Fujian and Yunnan mostly.Summer temp raises, and can't effectively discharge because of the heat that control apparatus work at the bottom of the blower fan tower produces, and causes blower fan high temperature alarm often to occur, and serious cause blower fan off-grid and control apparatus burn, and cause serious consequence.
Usually the tower tube of MW class blower fan generally is made up of cylindrical shell, electric and maintenance platform, cat ladder, access door etc., and control cabinet generally is installed on the electric platform in first section tower tube of tower tube at the bottom of the blower fan tower.In the long-time fan operation process of process; Equipment such as control cabinet will produce great amount of heat, and because tower barrel platform relatively seals, these heats are hoarded for a long time at the bottom of the blower fan tower; Certainly will cause at the bottom of the tower air temperature to rise and can't discharge; Cause the equipment high temperature alarm, reduce the operational efficiency of blower fan, cause economic loss.It is on tower tube access door, to offer a gas fan that is used to blow that tradition solves the method for dispelling the heat at the bottom of the tower, and the air that tower is outer is introduced in the tower, lowers the temperature; This mode is installed simply, can play certain cooling-down effect, but along with variation, the especially development of wind-powered electricity generation machine set technology in wind energy turbine set geographical position, the uptime of blower fan constantly increases, thereby the normal operation of control cabinet is proposed requirements at the higher level; Traditional radiating solution can not solve the too high problem of column bottom temperature.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to existing heat dissipation technology, provide a kind of structural design advantages of simple, dismounting convenient, effectively improve the blower fan tower barrel sink of fan operation efficient.
Technical problem to be solved by this invention is to realize through following technological scheme.The present invention is a kind of blower fan tower barrel sink; Be characterized in: this device comprises air-supply unit and the air draft unit that is fixed on the tower tube access door; The air-supply unit all is connected with electric control box, temperature detect switch (TDS) with the air draft unit; By the keying of temperature detect switch (TDS) control air-supply unit and air draft unit, the air intake tube of air-supply unit, the air draft tube of air draft unit all extend out to outside the tower tube access door.
In the blower fan tower barrel sink technological scheme of the present invention: described air draft unit preferred immobilization is on the top of tower tube access door, and the air-supply unit is preferably mounted at the bottom of tower tube access door.
In the blower fan tower barrel sink technological scheme of the present invention: the setting that is inclined upwardly of the exhaust outlet of described air draft tube, exhaust outlet and horizontal plane preferably are 65 °-85 °.
In the blower fan tower barrel sink technological scheme of the present invention: described air intake tube preferably is and is horizontally disposed with, and the intake grill of air intake tube preferably down.
In the blower fan tower barrel sink technological scheme of the present invention: preferably when temperature is higher than 40 ℃ in the tower tube; Temperature detect switch (TDS) is opened air draft unit and air-supply unit; When ambient temperature was equal to or less than 40 ℃ in the tower tube, air-supply unit and air draft unit were in holding state.
Among the present invention, introduce the outer Cryogenic air of tower through the air-supply unit that is provided with, be used to get rid of the inner high temperature air of tower tube through the air draft unit is set, electric control box is used to control air-supply unit and the work of air draft unit; Air-supply unit and air draft unit adopt temperature detect switch (TDS) control; When temperature is higher than setting temperature in the tower tube; Air draft unit and air-supply unit are opened; When ambient temperature in the tower tube is equal to or less than temperature is set time air-supply unit and the air draft unit is in holding state, start and stop through temperature detect switch (TDS) control blower fan and then can effectively organize the heat exchange of air in the tower tube effectively prolong the working life of blower fan simultaneously.
Air draft unit of the present invention preferably is installed on the tower tube access door according to upper-lower position with the air-supply unit, to realize the stable operation of air draft unit and air-supply unit; According to the hot air rising characteristic, the air draft unit is installed in tower tube access door top, to realize that hot air is discharged from a large number; Going out several mouthfuls and being inclined upwardly of the air draft tube of air draft unit can prevent that the heat that rainwater gets into and discharges from getting into the air-supply unit.The unit of will blowing is installed in tower tube access door bottom, to realize that cool air is introduced in the tower in a large number control cabinet is directly lowered the temperature; The intake grill of the turnover tube of air-supply unit is provided with down, can prevent that rainwater introducing tower is interior and avoid introducing the hot air that the air draft unit is seen off.
Electric control box can be installed on the suitable position of the electric platform of tower tube, and the temp probe of temperature detect switch (TDS) is placed on the temperature province that needs control and fixes, and the power switch of the controller that closes is made as desired temperature the value that needs; Through closure give, the automatic power supply switch of air bells exhauster, start air draft unit, air-supply unit simultaneously, to realize the heat radiation purpose.
Compared with prior art, blower fan tower barrel construction for heat radiating device of the present invention is provided with rationally, and is simple to operate, eliminated heat dissipation problem at the bottom of the blower fan tower greatly, improved the operational efficiency of blower fan.This device had both satisfied also blower fan and the long-time normal operation of control cabinet, need not carry out structural change to blower fan tower barrel again.
