The bottom end of the inner shell 21 inside the second-level Roots blower 7 is installed with a second-level air outlet pipe 8.

[0023] A dust filter 12.2 is provided at the top of the inner portion of the heat dissipation box 12.1. The dust filter 12.2 prevents dust and other impurities from entering the cooling box.

[0024] Example 2:

[0025] As shown in the attached figure of the instruction manual Figure 1 、 Figure 2 and Figure 3As shown, a two-stage Roots blower with a cooling device is shown. When in use, the first-stage Roots blower 4 and the second-stage Roots blower 7 are started through the control panel 2. A group of three-blade rotors 9 arranged inside the first-stage Roots blower 4 are staggered. A closed chamber is formed between the two three-blade rotors 9 inside the first-stage Roots blower 4. When the three-blade rotors 9 rotate continuously, gas is sucked in by the first-stage air inlet pipe 5 and discharged by the first-stage air outlet pipe 6. Due to the high-speed transportation of the gas, the gas temperature will increase. The circulating water pump 18 is started through the control panel 2, and the circulating water pump 18 transports the condensate in the condensate storage tank 13 through the liquid inlet pipe 19. The condensate flows out of the liquid outlet pipe 20 and is transported through the liquid outlet pipe 20 to the interior of the cooling pipe 22. Through the water inlet 24 provided on the surface of the sleeve 23, the condensate flows through the cooling pipe 22 and around the inner shell 21.

At the same time, through the provision of heat-conducting columns 15, the condensate in the condensate storage tank 13 transfers heat to the heat-conducting columns 15. Exhaust fan 12.4 cools the condensate while also cooling the heat-conducting columns 15. The hot air is then discharged to the outside through inclined exhaust holes 16, further enhancing the cooling effect of the condensate. The continuously cooled high-temperature gas finally enters the second-stage Roots blower 7 through the first-stage outlet pipe 6. The three-lobed rotor 9 in the inner casing of the second-stage Roots blower 7 rotates in the opposite direction to the three-lobed rotor 9 in the inner casing 21 of the first-stage Roots blower 4. The cooled gas is finally discharged through the second-stage outlet pipe 8 and enters the next production process.
