Further as a preferred embodiment, the air intake cooling section 100 includes a first box 110 provided with an air intake and an air outlet, and a first base 120 fixedly connected to the bottom of the first box 110; the first box 110 is internally provided with a primary filter 130, a nuclear grade cooler 140 and a condensate water tray 150 arranged below the nuclear grade cooler 140 in sequence from left to right, and the primary filter 130 and the nuclear grade cooler 140 are fixedly connected with the first box 110; the first box 110 is provided with a first chute 160 extending in the front-rear direction, one end of the first chute 160 is provided with a disengagement notch 161, and the condensate water tray 150 is slidably connected with the first chute 160. The primary filter 130 is capable of performing primary filtration, and is mainly used for filtering dust particles with a size of more than 5 μm, and is capable of effectively filtering impurities mixed in the inlet air. The core stage cooler 140 may employ a core stage heat exchanger as in the patent document with the grant publication number CN105180686 a. The condensation water tray 150 is slidably connected to the first chute 160, and the condensation water tray 150 can move along the first chute 160 and be separated from the separation notch 161, so that the condensation water tray 150 is convenient to detach and install, and the maintenance and cleaning are facilitated.
Further as a preferred embodiment, the upper slot wall of the first chute 160 is provided with a first baffle 162 extending downward, and a passing gap is provided between the first baffle 162 and the lower slot wall of the first chute 160; the left side of the condensate water tray 150 is provided with a first guide rail 151 extending along the front-rear direction, the first guide rail 151 is arranged in a first chute 160, and the first guide rail 151 is in sliding connection with the first chute 160; the left side of the first guide rail 151 and the upper side of the first guide rail 151 are respectively provided with an assembly gap with the first chute 160, and the right side of the first guide rail 151 is respectively provided with an assembly gap with the left side of the first baffle 162.

The first guide rail 151 provided on the condensate water tray 150 can extend into the first slide groove 160 through the clearance. The first guide rail is disposed in the first chute 160 to realize a front-rear sliding connection, and the first baffle 162 can effectively prevent the condensate water tray 150 from being outwardly biased during the front-rear movement. The first housing 110 is typically a welded structure, and after the components are welded together, there is typically some welding deformation, thereby creating some amount of warpage. The first guide rail 151, the first chute 160, and the first baffle 162 have an assembly gap, and can offset the welding deformation of the first case 110, thereby enabling smoother installation of the condensate water tray 150.

The left side of the core stage cooler 140 may be fixedly coupled to the first tank 110 by bolting. Because the condensate water tray 150 is slidably connected with the first chute 160, when the cross sleeper 170 abuts against the bottom of the nuclear level cooler 140, the condensate water tray 150 can support the bottom of the nuclear level cooler 140, and the nuclear level cooler 140 can compress the condensate water tray 150, so that the connection among the first box 110, the nuclear level cooler 140 and the condensate water tray 150 is firmer.
Further as a preferred embodiment, the upstream muffler section 200 includes a second casing 210 having an air inlet and an air outlet, a second base 220 fixedly connected to the bottom of the second casing 210, and a first resistive muffler 230 connected to the air outlet of the second casing 210; the second box 210 is provided with a first flow equalizing space 211, and the first flow equalizing space 211 extends from an air inlet of the second box 210 to an air outlet of the second box 210. The resistive muffler is a muffler which achieves the purpose of noise elimination by utilizing the characteristic that sound waves are transmitted in a porous sound absorption material or a sound absorption structure, and acoustic energy is converted into heat energy by friction to be emitted, so that noise transmitted along a pipeline is attenuated along with the distance. By arranging the first flow equalizing space 211, the airflow organization becomes uniform and the local resistance is reduced before entering the first resistive muffler 230, so that the noise reduction and elimination effect is effectively improved, and the service life of the components such as the first resistive muffler 230 is prolonged.

The detachable connection of the clamping member 233 and the bottom of the muffler case 231 may be by bolting or the like. When the clamping member 233 is detachable, and the interval between the silencing sheets 232 needs to be adjusted to change the silencing effect, the clamping member 233 is detached and the silencing sheets 232 with different widths are replaced. The left and right sides of the lower end of the sound damping sheet 232 are abutted against the clamping member 233, so that the sound damping sheet 232 is effectively clamped and fixed in the installation gap.
