Description
Technical Field
[0001] The utility model relates to the technical field of wet air cooler fans, in particular to a high-efficiency wet air cooler fan device. Background Art
[0002] Wet air coolers are air coolers that rely on air heating to remove heat, and rely on fin tubes, fans, and spray water to humidify and cool to enhance heat transfer. During the normal operation of the wet air cooler, due to the operation of the axial flow fan, cold air enters from the lower air inlet, and the hot air is discharged through the air outlet. Due to production process requirements, the air volume is adjusted by stopping a certain fan of the equipment. In this way, the hot air discharged by the fan will enter the running fan through the outlet of the stopped fan, causing a short circuit of the air and affecting the heat exchange effect of the equipment.
[0003] In workshop production, when a fan of the equipment is stopped, the hot air exhausted by other running fans will enter the fan through the air outlet of the stopped fan, causing a short circuit of the fan and affecting the heat exchange effect of the equipment. Utility Model Content
[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a high-efficiency wet air cooler fan device, which can only blow air from the blower to the wet air cooler box through the arrangement of an inclined air inlet duct, an inclined one-way movable plate and an inclined one-way movable plate shaft, thereby preventing hot air from entering the fan through the air outlet of a stopped fan, thereby reducing damage to the fan; through the arrangement of an anti-backflow tank, flushing water is prevented from entering the fan, thereby greatly improving the efficiency of normal production.
[0005] The utility model is realized by adopting the following technical solutions:
[0006] The high-efficiency wet air cooler fan device comprises a wet air cooler body and a blower. A heat exchange tube is arranged inside the wet air cooler body, an inclined air inlet pipe is arranged below the heat exchange tube, an inclined one-way movable plate is arranged between the inclined air inlet pipe and the wet air cooler body, the blower is connected to the inclined air inlet pipe through an anti-backflow tank, an inclined one-way movable plate rotating shaft is arranged between the inclined air inlet pipe and the inclined one-way movable plate, a spray port is arranged above the heat exchange tube, and an air outlet is arranged on the wet air cooler body.
[0007] The inclined air intake duct, the inclined one-way movable plate and the inclined one-way movable plate shaft are all inclined. The diameter of the inclined one-way movable plate is larger than the diameter of the inclined air intake duct. The inclined one-way movable plate can rotate around the inclined one-way movable plate shaft, so that air can only be blown from the blower to the wet air cooler box.
[0008] The air outlet is connected with an induced draft fan, a liquid phase outlet is arranged below the wet air cooler box, and a liquid phase outlet valve is connected to the liquid phase outlet.
[0009] An inclined baffle plate is arranged inside the anti-backflow tank, and the inclined baffle plate is connected with the horizontal movable plate through a horizontal movable plate rotating shaft.
[0010] The horizontal movable plate can rotate around the horizontal movable plate shaft. When flushing water overflows into the anti-backflow tank, the horizontal movable plate opens downward due to the gravity of the water, and the flushing water enters under the inclined baffle plate, thereby preventing the blower from getting water in.
[0011] The connection point between the inclined baffle plate and the backflow prevention tank is located below the connection point between the blower and the backflow prevention tank.
[0012] A spray conduit is arranged above the heat exchange tube, the spray port is connected to the spray conduit, and the spray conduit is connected to a liquid phase pipeline.
[0013] A spray ring is arranged below the spray conduit, the spray ring is connected to the liquid phase pipeline, and a spray port is arranged on the spray ring.
[0014] An oscillator is arranged on the vertical wall of the wet air cooler box.
[0015] The working principle of the utility model is:
[0016] After the wet air cooler starts working, the heat exchange tube and the blower are started, the mist is sprayed into the wet air cooler box through the spray port, the induced draft fan starts working, and the number of blower starts and stops is selected according to the production process requirements; when the wet air cooler efficiency becomes low, the oscillator starts working, and then the spray water is sprayed onto the heat exchange tube through the spray ring to spray and flush it, and the flushing water is discharged through the liquid phase outlet. Among them, the inclined air intake pipe, the inclined one-way movable plate and the inclined one-way movable plate shaft are all inclined, the diameter of the inclined one-way movable plate is larger than the diameter of the inclined air intake pipe, and the inclined one-way movable plate can rotate around the inclined one-way movable plate shaft, so that air can only be blown from the blower to the wet air cooler box. The horizontal movable plate can rotate around the horizontal movable plate shaft. When flushing water overflows into the anti-backflow tank, due to the gravity of the water, the horizontal movable plate opens downward, and the flushing water enters under the inclined baffle plate, avoiding water inflow to the blower.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] By adopting the utility model of the high-efficiency wet air cooler fan device, the air can only be blown from the blower to the wet air cooler box through the arrangement of the inclined air inlet duct, the inclined one-way movable plate and the inclined one-way movable plate rotating shaft, thereby preventing hot air from entering the fan through the air outlet of the stopped fan, thereby reducing damage to the fan; through the arrangement of the anti-backflow tank, flushing water is prevented from entering the fan, thereby greatly improving the efficiency of normal production; hot air can be blocked from entering the fan, thereby increasing the amount of cold air entering; while ensuring the entry of cold air, the fan can be stopped to save electricity; and the heat exchange efficiency of the air cooler can be ensured after the fan is stopped.
