A diffuser for a wind turbine where slots in said diffuser wall entrain air to enter into the diffuser with a swirl that is counter to the internal swirl created as a reaction to the turbine blades rotation as it extracts power such that the internal swirl and the externally introduced swirl cross over each other thereby causing vortices to form between them that energizes the internal flow and helps to prevent it from separating from the internal duct wall.; Such a diffuser would beneficially consist of a radial array of repeated segments each comprising a radial portion of a duct with a wing emerging from behind said duct leading edge and spiraling out and backwards and connecting back onto the wing of the next segment round such that each segment's wing connects to the trailing neighboring segment wing just as the leading neighbors wing connects onto it, and that a gap is left between the spiral arms to permit external air to flow between the trailing edge of one segment wing and the leading edge of the adjacent wing.

The invention relates to a double-atomization capturing electrostatic paint spray booth which comprises an electrostatic paint spray booth. An electrostatic spray nozzle is mounted in the electrostatic paint spray booth, a main water curtain plate and side water curtain plates are arranged on the inner wall of the electrostatic paint spray booth, a steam-water separation chamber is connected to the back of the main water curtain plate of the electrostatic paint spray booth, a bevel flushing plate is arranged on the lower portion of the main water curtain plate, the electrostatic paint spray booth is communicated with the steam-water separation chamber via a double-atomization paint mist capturing structure which is connected with the lower end of the bevel flushing plate, and a bottom plate flow guide structure is arranged at the bottom of the electrostatic paint spray booth. The double-atomization capturing electrostatic paint spray booth has the advantages that the double-atomization capturing electrostatic paint spray booth is simple in structure, scientific and reasonable in design, low in cost and high in paint mist capturing efficiency, and follow-up environmental protection treatment load can be effectively reduced.

The invention discloses an indoor air purifier. The indoor air purifier comprises a main case, a filter unit, a draught fan and an air exhaust device, wherein the filter unit and the draught fan are arranged in the main case, and the air exhaust device is arranged above the top of the main case. The top and the bottom of the main case are provided with openings. The two sides of the bottom of the main case are respectively provided with a support, so that the main case is suspended, and the opening in the bottom of the main case serves as an air inlet. The draught fan comprises a driving motor with two output shafts, wherein the driving motor is fixed into the main case, and the two output shafts of the driving motor are respectively connected with a wind wheel; a volute is arranged on the periphery of each wind wheel, and the upper end of each volute is communicated with the air exhaust device. Air can enter the bottom of the indoor air purifier at 360 degrees so that the requirement for large-area air purification can be met; air flow absorbed from the bottom can be exhausted from four sides of the top through the wind wheels on the two sides at the same time, and strong negative pressure is formed in an air flue, so more air can be absorbed in from the air inlet in the bottom, the adsorption capacity of the air inlet can be increased, more air can be filtered in a short time, the circulation speed of the air in a room can be increased to the maximum extent, and the efficient purifying effect can be achieved.

The present invention relates to a swash plate compressor with a rotary valve which can effectively siphon a coolant into a swash plate chamber through a cylinder block. The swash plate compressor comprises a housing connected to the cylinder block which has a plurality of cylinder bores, pistons which are accommodated and reciprocate in the respective cylinder bores, a drive shaft which is installed to rotate with respect to the housing and the cylinder block, a swash plate which is installed to be rotated by the drive shaft and interlock with the pistons, a valve plate which is interposed between the housing and the cylinder block, and the rotary valve which is formed to rotate along with the drive shaft and installed to roll in a joint hole formed in the cylinder block. A coolant outlet is formed on the exterior of the rotary valve, connection holes connected to the respective cylinder bores are formed on the interior of the joint hole which abuts against the exterior of the rotary valve, and a coolant inlet groove is formed to penetrate the swash plate chamber through to the housing. Therefore, loss caused by coolant inlet resistance can be remarkably reduced by siphoning coolant regardless of the torque of the drive shaft rotating at high speed.

The invention discloses a blowing hood gas escape prevention system and a control method thereof, comprising: a blowing hood located on the top of a sintering machine trolley; a blowing pipe row arranged inside the blowing hood and located on the sintering machine table The top of the car is used to spray combustible gas to the sintering material surface of the sintering machine trolley; the gas pipeline is used to transport combustible gas to the blowing pipe row; it is characterized in that it also includes: an air flow device, including a driving cylinder and A rotating impeller device, the rotating impeller device is arranged at the top area of ​​the blowing hood, and the rotating impeller device is used to drive the external air to generate an airflow and input the generated airflow from the top of the blowing hood downward into the spraying hood. Inside the hood, a wind pressure zone area is formed at the position above the row of blowing pipes so that the combustible gas cannot pass upwards. The anti-escape system can basically eliminate the phenomenon of gas escape, and helps to inhale the air outside the hood, so as to achieve the purpose of stable, smooth and high-quality production of the sintering production line.
