Example two
As shown in fig. 11, wherein the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, only the points of distinction from the first embodiment will be described below for the sake of brevity. The second embodiment is different from the first embodiment in that:
further, as shown in fig. 11, the cooling assembly includes a plurality of groups of first rotating assemblies 31a and second rotating assemblies 31b that are disposed at equal intervals along the length direction of the heat exchanger 1b and are staggered, the rotating directions of the first rotating assemblies 31a and the second rotating assemblies 31b are opposite, and each cooling assembly includes a swinging plate 311 that is rotatably disposed on the heat exchanger 1b, a tension spring 312 with one end fixedly connected with the swinging plate 311 and the other end fixedly connected with the side wall of the heat exchanger 1b, and a limiting block 310 that is disposed on the other side of the swinging plate 311 with respect to the tension spring 312, the swinging ends of the swinging plates 311 are in transmission connection with each other through a belt pulley, a third driving gear 313 is coaxially and fixedly disposed on the swinging end of any swinging plate 311, and a third driving rack 314 is fixedly disposed on the transmission rod 326 and is meshed with the third driving gear 313.
In detail, when the second driving rack 238 is driven to the limiting plate 321, the second control valve 232 is opened to the maximum exhaust amount and the air output of the fan 1a is completely closed at the same time, which means that the cooling environment in the heat exchanger 1b is problematic, the motor 251 continues to work, the telescopic unit b continues to drive, the moving telescopic unit b drives the driving rod 326 to move, and then the driving 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 reversely, and the door is blocked in the rotating process, so that the air pressure in the closed space between the two adjacent swinging plates 311 in the heat exchanger 1b is unchanged, the air pressure detection meter arranged at any position on the air pressure detection meter detects that the air pressure is stagnant for 1 minute, that is, and an alarm is sent, at this moment, the heat exchanger 1b can be checked for no refrigeration, generally, the cooling work is performed in the heat exchanger 1b, so that the temperature control precision meter is rapidly detected, and the switching plate 22 is driven to rotate, and the waste gas inside the heat exchanger 1b is rapidly enters the mechanism rapidly; it should be noted that, the third driving rack 314 has a unidirectional tooth structure, and the swinging plate is automatically reset by means of a tension spring.
In this embodiment, through setting up cooling subassembly cooperation fourth drive assembly 32, when realizing that second control valve 232 opens completely, actuating mechanism 25 utilizes fourth drive assembly 32 to drive cooling subassembly in step and works, when cooling subassembly swing to with heat exchanger 1b vertical state, waste gas is blocked at heat exchanger 1 b's inlet end, because fan air-out is closed this moment, whole heat exchanger 1 b's inlet end pressure reaches invariable, and then the pressure measuring ware that sets up this moment can send the alarm, the manual regulation carries out the cooling work in to heat exchanger 1b, when waste gas reaches the temperature that satisfies the condition, switch board 22 rotates, waste gas gets into output mechanism, whole work works 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 to the inner wall of the heat exchanger 1b, and a rounded corner is disposed on a side of the swing plate that contacts with the inner wall of the heat exchanger 1b simply, so as to avoid damage to the inner wall of the heat exchanger 1b when the swing is in the closed state.
In addition, by using the first rotating assembly 31a and the second rotating assembly 31b, the exhaust gas flows 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 cooling efficiency of the exhaust gas is improved.
The working process comprises the following steps:
the waste gas containing heat is blown into the heat exchanger 1b through the fan 1a to carry out preliminary cooling of the waste gas, the gas is condensed, the first rotating component 31a and the second rotating component 31b are arranged, the waste gas is transmitted in an S shape in the heat exchanger 1b, the contact time of the Tibetan waste gas and the heat exchanger 1b is prolonged, 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 a tee joint, when the temperature control precision meter detects that the temperature of the air flow output in the heat exchanger 1b is higher than a certain fixed value, the liquid possibly exists in the waste gas and is not thoroughly liquefied, the first transmission component 253 drives the switching plate 22 to rotate, and the waste gas is rotated into the heat exchanger 1b again through the circulating mechanism 23 to carry out secondary cooling operation of the waste gas; when the temperature control precision meter detects that the temperature of the air flow output by the heat exchanger 1b is lower than a certain value, the temperature control precision meter can judge that certain liquid in the waste gas is fully liquefied at the temperature, and then the first transmission assembly 253 drives the switching plate 22 to rotate, the waste gas is transmitted to the rotary separator 1c through the output mechanism 24 to carry out the gas-liquid thorough separation work, the separated liquid flows out and is collected through the water outlet at the lower part, the separated gas enters the gas-liquid mixing tower 1e through the air outlet at the upper part, the waste gas is contacted with water in the gas-liquid mixing tower 1e, other related harmful mediums are treated again, other solvents can be added into the water to carry out waste gas purification through chemical reaction, and the waste gas is discharged after the purification.
