Description
Technical field
The utility model relates to a kind of energy-saving roof ventilator, belongs to the manufacturing technology field of blower fan.
Background technology
Roof ventilator is the ventilation equipment that are applied to produce particular surroundings such as damp, the existing product such as the patent No. are that 01221715.8 fiberglass explosion-proof roof fan mainly is made of air duct, blast cap, blower fan, bird prevention net, safety net, air-valve and driver etc., bird prevention net and safety net can prevent effectively that foreign matters such as worm, bird from entering in the pedestal, can also prevent that foreign matter from falling, to guarantee equipment and personnel's safety.But owing to there is not automaton, make blower fan be in the long-term operation state, influenced energy-saving effect.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively improve the energy-saving roof ventilator of energy-saving effect.
The utility model is energy-saving roof ventilator, comprise square base with circular air duct and the long-pending square transition structure of circle, be fixed in the rainproof blast cap of air duct top band bird prevention net, place the axial flow blower that constitutes by motor and aluminium alloy impeller in the circular air duct, place air-valve and safety guard net in the square base, it is characterized in that also being provided with between described air-valve and the safety guard net intelligent attemperating unit.
Described intelligent attemperating unit can place the axle center of air-valve or all around, links to each other with the controller of peripheral hardware.
Described circular air duct, the long-pending square transition structure of circle, square base can be the Contiuum type structure.
Described square base also can be provided with the electric operator that links to each other with air-valve outward.
The utility model is reasonable in design, in the bottom of air-valve intelligent attemperating unit is set, can set the operation that opens and closes air-valve and blower fan by temperature, the special mechanical exhaust operation that when spring, autumn, winter and nocturnal temperature temperature are relatively low, can stop roof ventilator, only need to open air-valve by the temperature setting, utilize hot pressing can carry out natural exhaust, thereby can save the operation power consumption of roof ventilator greatly, play energy saving purposes.In addition, circular air duct and square base are formed conjoined structure by the circle-square reducing transition of the long-pending square transition structure of circle, can further improve the air intake air-flow of blower fan, ensure the performance of blower fan.
Description of drawings
Accompanying drawing has provided overall structure half sectional view of the present utility model.
The specific embodiment
The utility model is mainly by the square base 8 with circular air duct 6 and the long-pending square transition structure 7 of circle, be fixed in the rainproof blast cap 5 of circular air duct 6 top band bird prevention nets 2 and crampon 4, place motor 3 and aluminium alloy impeller 1 in the circular air duct 6, place in the square base 8 safety guard net 11 and with the air-valve 10 of electronic executing agency 9, place the formations such as intelligent attemperating unit 12 between air-valve 10 and the safety guard net 11.Intelligent attemperating unit 12 can place air-valve 10 the axle center and or all around, circular air duct 6, the long-pending square transition structure 7 of circle, square base 8 are the Contiuum type structure, motor 3, air-valve 10, intelligent attemperating unit 12 all link to each other with the control cabinet of peripheral hardware.
During use, the utility model is installed on the building roof, connects power supply, by intelligent attemperating unit 12 design temperature X values, Y value X value＜Y value, when temperature reached the X value of setting, air-valve 10 was opened in electric operator 9 runnings, and can utilize hot pressing to carry out natural exhaust this moment; When temperature reaches the Y value, motor 3 runnings, blower fan promptly runs well and carries out mechanical exhaust.The bird prevention net 2 on circular air duct 6 tops and 11 of the safety guard nets of square base 8 bottoms can prevent that blower fan from preventing that foreign matters such as worm, bird from entering in the air duct and preventing that foreign matter from falling when turning round or quitting work; 5 of the rainproof blast caps on circular air duct 6 tops play rainproof and effect wind-guiding.
The utility model is through actual motion, with 2 * 600MW unit thermal power plant is example, normal power generation need installation power is that 66 of the roof ventilators of 5.5KW carry out mechanical exhaust, turning round needed power consumption 8712 degree 5.5KW * 66 * 24 hours=8712 degree in 24 hours, move by attemperating unit as blower fan, night 20 when 8 o'clock mornings of next day, outdoor temperature was relatively low, can utilize hot pressing to carry out natural exhaust by opening air-valve, but this measure power saving 50%, but be power saving every day 4356 degree, but power saving in every month 130680 degree, but power saving in every year 1568160 degree.By 0.8 yuan of calculating of every degree electricity price, can save 125.4528 ten thousand yuan of the electricity charge in 1 year.As add the lower period of spring, autumn, winter temperature and adopt natural exhaust, calculate by operation in three months 90 days 12 hours, but 392040 degree 5.5KW * 66 of power saving still * 12 hours * 90 days=392040 degree can be saved 31.3632 ten thousand yuan of the electricity charge.This shows, can save power consumption greatly, can obtain good economic benefit and energy-saving effect.The utility model can be widely used in thermal power plant, nuclear power plant, reach the heat extraction ventilation of other industrial premises.
