further, as shown in fig. 11, the cooling assembly includes a plurality of sets of first rotating assemblies 31a and second rotating assemblies 31b arranged along the length direction of the heat exchanger 1b at equal intervals and staggered with each other, the first rotating component 31a and the second rotating component 31b have opposite rotating directions and each include a swinging plate 311 rotatably disposed on the heat exchanger 1b, a tension spring 312 having one end fixedly connected to the swinging plate 311 and the other end fixedly connected to the side wall of the heat exchanger 1b, and a limit block 310 disposed on the other side of the swinging plate 311 relative to the tension spring 312, the swinging ends of the swinging plates 311 are in transmission connection through belt pulleys, a third driving gear 313 is coaxially and fixedly arranged on the swinging end of any swinging plate 311, a third driving rack 314 is fixedly arranged on the transmission rod 326, and the third driving rack 314 is meshed with the third driving gear 313.
In detail, when the second transmission rack 238 is transmitted to the limiting plate 321, the second control valve 232 is opened to the maximum exhaust air volume and the air volume of the fan 1a is completely closed, which indicates that a problem occurs in the cooling environment in the heat exchanger 1b, the motor 251 continues to operate, the expansion unit b compresses, the expansion unit b continues to transmit, the movable expansion unit b drives the transmission rod 326 to move, the transmission rod 326 drives the third driving rack 314 to drive the third driving gear 313 to rotate, the two rotating third driving gears 313 respectively drive the first rotating assembly 31a and the second rotating assembly 31b to rotate in opposite directions, and the door is blocked during the rotation process, so that the air pressure in the closed space between two adjacent oscillating plates 311 in the heat exchanger 1b is not changed, and the air pressure detecting meter disposed at any position thereon detects that the air pressure is standing for 1 minute, the alarm is given, and the heat exchanger 1b can be checked manually to be not refrigerated at this time, generally, the interior of the heat exchanger 1b is cooled firstly, so that the temperature control precision meter can detect quickly, the switching plate 22 is driven to rotate, and then the exhaust gas in the heat exchanger 1b enters the output mechanism quickly; it should be noted that the third driving rack 314 is a unidirectional tooth structure, and the swing plate is automatically reset by a tension spring.
In this embodiment, through setting up cooling assembly cooperation fourth transmission assembly 32, when realizing that second control valve 232 opens completely, actuating mechanism 25 utilizes fourth transmission assembly 32 to drive cooling assembly in step and carries out work, when cooling assembly swings to with heat exchanger 1b vertical state, waste gas is by the separation at the inlet end of heat exchanger 1b, because the fan air-out was closed this moment, the inlet end pressure of whole heat exchanger 1b reaches unchangeably, and then the pressure detector that sets up at this moment can send out the police dispatch newspaper, manual adjustment is to carrying out cooling work in the heat exchanger 1b, when waste gas reaches the temperature that satisfies the condition, switch plate 22 rotates, waste gas gets into output mechanism, whole work is worked once more, guarantee the stability of work, its synchronism is strong and save extra power output.
It should be noted that, when the tension spring 312 is in the initial state, the swing plate 311 is disposed at a certain angle with the inner wall of the heat exchanger 1b, and the side of the swing plate that is in simple contact with the inner wall of the heat exchanger 1b is disposed with a rounded corner, so as to avoid damage to the inner wall of the heat exchanger 1b when the swing is in the closed state.
In addition, the first rotating assembly 31a and the second rotating assembly 31b are utilized to enable the exhaust gas to flow in the heat exchanger 1b in an S shape under normal conditions, so that the flowing time of the exhaust gas in the heat exchanger 1b is increased, and the exhaust gas cooling efficiency is improved.
The working process is as follows:
waste gas containing heat is blown into the heat exchanger 1b through the fan 1a to carry out primary cooling of the waste gas, so that the gas is condensed, the first rotating component 31a and the second rotating component 31b are arranged, the waste gas is transmitted in the heat exchanger 1b in an S shape, the contact time of the house keeping waste gas and the heat exchanger 1b is kept, condensed liquid finally flows out from a liquid outlet to be collected, when the waste gas passing through the heat exchanger 1b is transmitted to the tee joint, when the temperature control precision meter detects that the temperature of the air flow output from the heat exchanger 1b is higher than a certain value, the liquid in the waste gas possibly does not completely liquefy, the first driving component 253 drives the switching plate 22 to rotate, the waste gas is rotated into the heat exchanger 1b again through the circulating mechanism 23, and secondary cooling work of the waste gas is carried out; when the temperature control precision meter detects that the temperature of the air current output in the heat exchanger 1b is lower than a certain value, it can be judged that some liquid in the waste gas is fully liquefied at the temperature, and then the switching plate 22 is driven to rotate through the first transmission component 253, the waste gas is transmitted to the rotary separator 1c through the output mechanism 24, the complete gas-liquid separation work is carried out, the separated liquid flows out and is collected through a water outlet at the lower part, the separated gas enters the gas-liquid mixing tower 1e through a gas outlet at the upper part, the waste gas is contacted with the water in the gas-liquid mixing tower 1e, other related harmful media are treated again, other solvents can be added into the water, so as to carry out waste gas purification through chemical reaction, and the waste gas is discharged after purification.
