Technical Field
The utility model relates to a fan filter unit especially relates to an environment-friendly direct current fan filter unit.
Background
FFU is called (Fan Filter Unit) in English, and Chinese is a Fan Filter Unit. But FFU fan filter screen unit modularization connects the use, uses FFU wide application in application occasions such as toilet, clean workstation, clean production line, assembled toilet.
In the world today, the microelectronics and optoelectronics industries have become the foundation and platform for the development of national economy and science and technology, and are also important signs for measuring the economic and scientific and technical level of a country and a region. Along with the rapid development of the electronic industry, the requirement on the cleanliness of an ultra-clean factory building is higher and higher, the cleanliness grade of the ultra-clean factory building mainly depends on the performance of the FFU, and the energy consumption index is the key for measuring the performance of the FFU.
The fan is the core part of the FFU, the change of the performance of the fan can greatly affect the overall performance of the FFU, so that an environment-friendly direct current FFU is designed and developed, the FFU adopts a direct current brushless EC motor, the motor efficiency is up to 90%, and the efficiency of an alternating current motor is only about 65%; the direct current motor is integrated with the controller and the drive into a whole, and actively corrects the power factor, so that the power factor is improved, the reactive power is reduced, and the energy consumption is reduced; on the other hand, various losses are generated in the gas flowing process, wherein the magnitude of the hydraulic loss is closely related to the geometric shape of the gas flow component, the wall roughness and the viscosity of the fluid.
Disclosure of Invention
To above technical problem, overcome original structure because the runner suddenly expands, pressure crescent, there is great pressure gradient in this region, and the fluid takes place the backward flow at the runner exit region from high-pressure side flow direction low pressure end, arouses pressure reduction and energy loss' S not enough, the utility model discloses an environment-friendly direct current FFU has the box, is provided with the FFU fan in the box, is provided with air intake and air outlet respectively in box top and bottom, is provided with two baffles that keep out the wind in the box, forms S type drainage channel between two baffles, S type drainage channel is located the mouth that opens of outside direction and is expanded outward gradually by the FFU fan. The S-shaped drainage channel changes the flow channel structure, so that the shape of the flow channel is changed slowly, the sudden expansion structure is eliminated, the flow velocity of each part of the flow channel is equal under the condition of certain flow, the pressure of each part tends to be equal, large pressure gradient cannot occur, and backflow and energy loss caused by the backflow cannot be generated.
In order to reduce the wind-out resistance as much as possible, further: the S-shaped drainage channel is composed of an arc guide plate and a flaring guide plate, the arc guide plate is located on the periphery of the FFU fan, the flaring guide plate is connected with the arc guide plate and extends towards the side wall of the box body, the arc circle center of the arc guide plate and the rotating shaft of the FFU fan are coaxial, the arc guide plate and the flaring guide plate are in tangent connection at the position close to the air outlet of the FFU fan, a guide bevel is arranged at the connection position of the arc guide plate and the flaring guide plate at the far air outlet position of the air outlet of the FFU fan, and the guide bevel is of an arc structure. The arc-shaped guide plate and the flaring guide plate are designed in a cutting mode, so that when air is supplied to the outside of the FFU fan, the air supply direction is consistent with the direction of the flaring guide plate, in addition, the guide folding angle is of an arc structure, the flow resistance of the guide folding angle to air flow is effectively improved, the S-shaped drainage channel guides the air flow, the resistance of the S-shaped drainage channel to the air flow is reduced as far as possible, the impact of the air flow and the S-shaped drainage channel is reduced, and the extra energy loss when the air flow generates cyclone vortex in the drainage channel is reduced.
In order to make the air that FFU fan sent out to the air outlet more balanced, further: and an air deflector is arranged in the S-shaped drainage channel and is fixedly connected with the opposite side wall of the box body. The air guide plate is used for distributing air to the air outlet, a part of air flow directly reaches the air outlet below after reaching the air guide plate, and a part of air flow bypasses the air guide plate and then reaches the air outlet downwards. In addition, the guide plate is added, the internal structural resistance is reduced, the air quantity is improved on the original basis, the power is obviously reduced, and the purpose of energy conservation is realized.
In order to facilitate the fixing and installation of the FFU fan in the box body, the FFU fan further comprises: a hanging bracket consisting of a hanging rod and a bottom plate is hung in the box body, and the FFU fan is installed on the hanging bracket. The hanging bracket structure can fix the FFU fan and reduce the air supply interference of the fixing structure to the FFU fan as much as possible. In addition, a cavity is formed between the FFU fan and the high-efficiency filter, dynamic pressure flowing out of the fan in the cavity is converted into static pressure, the distance between the bottom plate and the top surface of the FFU is increased, namely the volume of the static pressure cavity is increased, and meanwhile, the area of the bottom plate is reduced, so that uniform air outlet around the FFU is facilitated, air outlet resistance is reduced, and energy consumption is reduced.
In order to effectively purify and filter air, an air inlet filter screen is arranged at an air inlet, and a high-efficiency filter is arranged at an air outlet.
The utility model discloses effectively improve the mobile loss of air current in the box, reduced the work energy consumption, improved air supply efficiency.
