Embodiment
Embodiment：
Refering to Fig. 4 to Fig. 7, one kind boat changes the light-duty combustion engine air inlet cooling system of type, including 12 row's coil pipes 1, and the inlet plenum 2 positioned at both sides；The 12 row coil pipe 1 is bolted to the inner frame of both sides inlet plenum 2；The 12 row coil pipe 1 also includes import and export cold water pipes, pipe clamp, the vent valve being sequentially connected；Both sides inlet plenum 2 respectively has installation dehumidifier 3 after the row's coil pipe of 2 tunnel, 12 row's coil pipe 1,12, and the condensed water for removing refrigeration coil generation, material is anti-aging hard PVC.
Further comprise reserved dehumidifier mounting bracket, the dehumidifier size is adapted to according to neck size and location site cutting.
The bottom of both sides inlet plenum 2 respectively increases a condensate draining 4.
The discharge outlet of condensate draining 4 is provided with the drainpipe for being used for discharging condensed water.
A set of prefilter framework and installation door 5 are installed additional on the outside of the upstream framework of 12 row's coil pipe 1.
After understanding that charge air-cooling system comes into operation refering to Fig. 1 to Fig. 3, combustion engine exert oneself and efficiency can all be significantly improved, and the raising that combustion engine is exerted oneself can also be such that fuel consumption accordingly increases.Exhaust gas temperature is returned after charge air-cooling system input and decreased, but due to the increase of Fuel Consumption, smoke evacuation flow can significantly rise, in general, and smoke evacuation energy can also be significantly improved.In combined cycle, the exhaust gas temperature of gas turbine determines the height of main steam temperature, and smoke evacuation flow determines the size of quantity of steam.For this project, the reduction of exhaust gas temperature is not high, does not interfere with main steam temperature.Therefore exerting oneself and efficiency for combustion engine can be not only carried in the input of hot summer charge air-cooling system, can also increases the yield of steam.
The original 2 row coil pipe of shen village's LM6000PF+SPRINT units is removed, coil pipe can be removed directly to be bolted to both sides inlet plenum inner frame, while import and export pipeline, pipe clamp, vent valve that having of needing to dismantle is connected with 2 row's coil pipes etc..There is the row's coil pipe of 2 tunnel 2 per side, totally 4 tunnel.Coil pipe weight parameter：The row's heating coil weight of single channel 2 is about 0.6 ton, totally 4 tunnel.
12 row's coil pipes and corresponding component are installed；12 row's coil pipes are to be bolted to both sides inlet plenum inner frame.After coil pipe is installed in place with bolt, import and export cold water pipes, pipe clamp, vent valve that installation is connected with 12 row's coil pipes etc..Both sides inlet plenum respectively has the row's coil pipe of 2 tunnel 12, totally 4 tunnel.The inlet plenum of both sides can install 12 row's cooling coils, and the thickness of 12 row's coil pipes is about 560mm, and coil pipe lifting cover plate opening size is enough.
Coil pipe weight parameter：The row's heating coil weight of single channel 12 is about 3 tons, totally 4 tunnel.
Dehumidifier is installed after 12 row's coil pipes, the condensed water for removing refrigeration coil generation, material is anti-aging hard PVC.Shen village's unit has reserved dehumidifier mounting bracket, it is not necessary to additionally install additional, and dehumidifier size is adapted to according to neck size and location site cutting.
Condensate draining is installed：Both sides inlet plenum bottom respectively increases a condensate draining, and condensate draining shifts to an earlier date processing and fabricating, and scene needs to be welded and fixed support.Because condensate draining is in the filtering positive bottom in room, site operation will build scaffold.
Both sides condensate draining discharge outlet needs one drainpipe of each increase, for discharging condensed water, and station internal drainage pipeline is voluntarily connected to by client.Dress insulation material is applied outside condensate draining.
Install a set of prefilter framework and installation door additional on the outside of 12 row's coil pipe upstream frameworks, the installation frame will can either ensure the sealing before and after prefilter, prefilter quick-replaceable is disclosure satisfy that again.Totally 16 fans are welded and fixed work, it is necessary to which scene carries out part per side inlet plenum for prefilter installation frame and installation door.
Increase prefilter can be obviously improved the air mass of combustion engine, extend fine filter service life, protect 12 row's refrigeration coils.Prefilter can be changed online, facilitate operation maintenance, reduce air intake filter use cost.Prefilter quantity is 160, model DPGT-405, the synthetic fibers of material 100%.The model filter is applied widely, possesses the ability of steam in resistance air, prefilter is the grades of MERV 8 (ASHRAE 52.2 1999, substantially identical to G4 grades of EN 779), can be to the interception quantity of 3-10 microns in air (less than 10 microns of dust can not visually be seen) particulates more than 70%；Initial resistance is low, and according to design ventilation, initial resistance is only 0.18 inch (45 Pa)；Dust containing capacity is big, and design maximum resistance is 1 inch (254 Pa).
In order to improve power of the combustion engine in summer, cooling water pipe is installed additional in air inlet device, introduce the chilled water of lithium bromide chilled water pipe, so as to reduce combustion engine air themperature, cooled down to improving combustion engine power and improving combustion engine casing, there is good effect.
