The invention discloses a combined screw divert plate tubular heat exchanger, wherein, in one pitch, the screw divert plate is radial divided into inner and outer parts; the central area in the frame has discontinuous inner screw while outside the central area, uses continuous annular screw divert plate to form continuous outer screw; the outer screw divert plate surrounds the inner screw divert plate. For the horizontal heat exchanger, when the medium is accumulated with dirt, the nearby outer screw divert plate is mounted to make the connection at the bottom of heat exchanger, and the outer edge of each connection has a cut at the connected part. The invention can reduce flowing resistance, improve heat exchange efficiency and improve the service life. The invention also provides the method for processing the continuous screw divert plates, to confirm the concentric property of holes of divert plate.

The invention discloses a mist-removing filler, which is composed of a plurality of heat exchange fins arranged, and a first channel and a second channel which are arranged at intervals and are not connected to each other are formed between the plurality of heat exchange fins. Each heat exchange fin includes: a plurality of baffle surfaces; a flow guide groove, which extends outward from the intersection of two adjacent baffle surfaces up and down, and the lower part of the flow guide groove forms a flow guide surface, and the flow guide The surface is deflected downward relative to the baffle surface below it; and the liquid collecting tank is surrounded by the upper part of the diversion groove and the deflecting surface above it, and the liquid collecting groove and the diversion groove above form a semi-closed diversion space. The invention also discloses a mist elimination cooling tower. The fog-eliminating cooling tower and its fog-eliminating filler of the present invention can more effectively capture the water mist in the hot and humid air through the cooperation of the diversion groove, the diversion surface and the liquid collection tank, and improve the effect of defogging and water saving.

The invention discloses an air conditioner oil return system, a method and an air conditioner. The problem that because the oil return temperature is too high in the oil return process of the air conditioner in the related art, the heat exchange effect of the system is influenced is solved. The air conditioner oil return system comprises a first oil separator, a first oil return pipeline and a controller, wherein an inlet of the first oil separator is connected with an exhaust port end of a compressor in the air conditioner, and the first oil separator is used for receiving oil-gas mixture discharged by the compressor connected with the first oil separator and separating the oil-gas mixture. The oil return pipeline is used for conveying the oil separated by the first oil separator to a compressor in the air conditioner. The controller is used for controlling the air conditioner to run when the air conditioner returns oil, and the air supplementing flow of the air supplementing loop ofthe compressor is adjusted according to the air supplementing superheat degree of the compressor in the air conditioner, so that the oil return temperature of the air conditioner is reduced. Accordingto the system and the method, the problem that because the system oil return temperature is too high, the system heat exchange effect is influenced is solved.

The invention discloses a ship exhaust gas waste heat recovery system with a secondary recovery function and relates to the technical field of ship exhaust gas recovery. The system comprises a bottomplate and an exhaust gas tube; supporting plates are fixedly connected on the two sides of the top of the bottom plate; a first fixed plate and a second fixed plate are fixedly connected to the bottoms and the tops, between the opposite sides, of the two supporting plates correspondingly; a temperature difference power generator is arranged on the surface of the bottom plate in a penetrating mode;one side of the temperature difference power generator communicates with one end of the exhaust gas tube; and a first water storage tank and a second water storage tank are fixedly connected with thetwo sides of the top of the first fixed plate from left to right. The invention relates to the technical field of ship exhaust gas recovery. Through the ship exhaust gas waste heat recovery system with the secondary recovery function, exhaust gas can be secondarily recycled, the utilization rate of waste heat in the exhaust gas is increased, the practicability of the system is improved, rust scale and deposits on the inner walls of a first tube, a first heat exchange tube, a second heat exchange tube and a second tube can be removed, and the situation that impurities are accumulated for a long time, and consequently the heat exchange effect is affected is avoided.
