The principle is as follows: the bubbles generated in the production process are broken by using centrifugal force, so that gas and liquid are separated, the bubbles are quickly torn by the shearing force provided by the high-speed rotating module, the liquid released by the bubbles is immediately thrown to the wall of the reactor by the centrifugal force, and is compressed into liquid flow to return to the reaction kettle again, and the loss of the escaping liquid is reduced.

Run through on the lateral wall of casing 1 and seted up air inlet 9, fixed mounting has dust screen 10 on the inside wall of air inlet 9, including one side fixedly connected with side support body structure that is close to air inlet 9 on 1 lateral wall of casing, the structural rotation of side support body is connected with belt conveyer, and side support body structure includes two curb plates 11 of fixed connection on 1 lateral wall of casing, and two curb plates 11 set up the both sides at air inlet 9 respectively, and belt conveyer sets up between the relative lateral wall of two curb plates 11.

Fixedly connected with horizontal pole 15 on belt conveyor's the lateral wall, horizontal pole 15 is close to the fixed brush 16 that is provided with in one side of air inlet 9, and brush 16 laminates with the outer wall of dust screen 10 mutually, is provided with the ash collecting box 17 that the top has the open-ended under belt conveyor, and ash collecting box 17 fixed mounting is on the lateral wall of casing 1, and one side that shell 1 was kept away from to ash collecting box 17 fixed connection has scraper blade 18 to the slope of casing 1. The top of scraper blade 18 is equipped with the certain distance with the outside of conveyer belt 14, and when brush 16 moved to the top position that is close to scraper blade 18, horizontal pole 15 can not be scraped with scraper blade 18, and brush 16 can be scraped with scraper blade 18, and at brush 16 and the mutual scraping process of scraper blade 18, scraper blade 18 can be scraped the bulky dirt attached to brush 16 down, avoids brush 16 to cross dirty and unable normal cleanness.

The belt conveying device comprises two rotating shafts 12 which are rotatably connected to opposite side walls of two side plates 11 and are distributed up and down, opposite ends of the two rotating shafts 12 are in conveying connection through a conveying belt 14, specifically, two driving wheels 13 are mounted on the two rotating shafts 12, and the two driving wheels 13 which are opposite up and down are driven through the conveying belt 14. The transverse bars 15 are fixedly connected to opposite side walls of the two conveyor belts 14. A motor 19 for driving one of the rotating shafts 12 to rotate is fixedly mounted on the side wall of the side plate 11. In addition, a chain and gear combination may be used to drive the cross bar 15.

Example two

Referring to fig. 1-2, on the basis of the first embodiment, further setting: a water distribution system 5 is fixedly arranged in the shell 1, and the water distribution system 5 is positioned above the filler 2. An exhaust pipe 3 is fixedly arranged on the side wall of the top end of the shell 1, a water outlet 8 is fixedly arranged on the side wall of the bottom end of the shell 1, and a demister 6 is fixedly arranged on the inner side wall of the top end of the shell 1 and close to the exhaust pipe 3. The demister 6 mainly comprises fixing devices such as wave-shaped blades, plates, clamping strips and the like. When the gas containing water mist passes through the demister 6, the movement direction is changed rapidly and continuously, and due to the action of centrifugal force and inertia, the fog drops in the air impact the blades to be captured, the fog drops are converged to form water flow, and fall into the chamber 1 due to the action of gravity, so that gas-liquid separation is realized.

The working principle of the cross-flow cooling tower with the automatic defoaming function is as follows: the water can be distributed downwards through the water distribution system 5, and the water body can flow downwards through the filler 2. In-process, start axial fan 4 inside exhaust pipe 3 in step for during the outside air can inhale casing 1 through air inlet 9, the water contact heat transfer in air and the filler 2 can cool off the water, and the air is behind the defogger 6 defoggers afterwards, outside casing 1 is discharged by exhaust pipe 3. Through set up mechanical defoamer 7 in casing 1 inside, can carry out the defoaming to the foam that the water of casing 1 bottom produced, prevent that the foam from discharging together and polluting the environment along with the air.

The dust screen 10 can filter dust from air entering the housing 1, and the filtered dust can adhere to the outside of the dust screen 10. During operation of the cooling tower, the motor 19 may be started at a predetermined time, and the motor 19 may rotate one of the shafts 12. Because the two rotating shafts 12 on the two side plates 11 are in transmission connection through the conveyor belt 14, the conveyor belt 14 can be circularly transmitted between the two rotating shafts 12 when the rotating shafts 12 rotate. The cross bar 15 on the side wall of the conveyor belt 14 can move along an annular path along with the conveying of the conveyor belt 14 (taking fig. 4 as an example, the cross bar 15 moves counterclockwise along with the conveyor belt 14), when the cross bar 15 is conveyed to one side of the conveyor belt 14 close to the dust screen 10 along with the conveying of the conveyor belt 14, the cross bar 15 moves downward, the brush 16 on the side wall of the cross bar 15 can brush the dust on the outer wall of the dust screen 10 downward, the automatic cleaning function of the outer wall of the dust screen 10 is realized, and the dust can be further brushed off from the dust screen 10.

When the brush 16 on the side wall of the cross bar 15 moves to the bottom of the conveyor belt 14, the brush 16 on the side wall of the cross bar 15 can be scraped against the top end of the scraper 18 along with the transmission of the conveyor belt 14, and the scraper 18 can clean the dust on the brush 16, so that the normal cleaning capability of the brush 16 is prevented from being influenced by a large amount of dust attached to the brush. And the dust cleaned from the dust screen 10 can fall under the action of gravity into the dust-collecting box 17 to be collected concentratedly.

It should be noted that the specific model specification of the motor 19 needs to be determined by model selection according to the actual specification of the device, and the specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
