The present invention is directed to the deficiency in the presence of prior art, provide a kind of forward type combustion engine air inlet coarse filter device and using method, the present invention i.e. sets up air coarse filter device outside combustion engine air intake filter, and the present invention is as single filter, first to diameter in air 10 μm
Above dust granules filters；5 μm that air after filtration carries again by combustion engine itself
Accurate filter carries out cascade filtration, combustion engine accurate filter so can be made to be extended to 12 months by 3 months service life, and when changing coarse filter device of the present invention, combustion engine need not be shut down, and greatly reduces combustion engine machine stop times and time.Technical scheme is as follows:
A kind of forward type combustion engine air inlet coarse filter device, including steel structure frame, described steel structure frame is rectangular-shaped, the side of described steel structure frame is provided with maintenance door, described steel structure frame three face is respectively equipped with a square bearer, and described square bearer is provided with multiple square frame pocket type coarse filter, and the one side of described steel structure frame is docked with combustion engine air inlet, bottom and top seal, described square bearer is air inlet.
Further, in the present invention, described steel structure frame bottom is provided with bracing frame, and support frame as described above is provided with staircase.
Described square bearer is steel construction, and square frame pocket type coarse filter is embedded on square bearer, can pull down cleaning, reassemble after drying, and it is 54 that each square bearer is provided with the sum of square frame pocket type coarse filter；Preferably, the filter element of described square frame pocket type coarse filter selects the preferable terylene of breathability molten spray material；Filter element thickness is 20mm；The high performance nonwoven fabric being made up of the organic synthetic fibers of Resisting fractre processes, waterproof, corrosion-resistant；And filter element uses incremental structure, the i.e. fibrolaminar density toward pure air direction to be gradually increased, increasing the service life, use binder-treatment, make dust particle to pass through, filtering accuracy is up to 10 μm
；It has can water scrub function, can repeatedly clean 2-3 time.
The top of described forward type combustion engine air inlet coarse filter device uses PC sunlight board, can be with daylighting.
It is provided with shutter outside each square frame pocket type coarse filter, the material of described shutter is aluminium-plastic panel, shutter changes air flow and flow velocity, the work principle of filter such as interceptions, shock is used to carry out intercepting filtration to the dust of big particle, leaves, feather, rainwater etc., there is rainproof and air inlet fence effect, play pre-filtering and uniform flow effect, simultaneously, make coarse filtration facility attractive in appearance, strengthen visual effect.
Present invention also offers a kind of forward type to fire the using method of machine air inlet coarse filter device, step is as follows:
(1) before combustion engine is started shooting, each filter element of forward type combustion engine air inlet coarse filter device checks whether intact, to having blocked serious being replaced, it is ensured that each filter element can normally work；
(2), after filter element checks, close maintenance door, check the encapsulation situations of forward type combustion engine air inlet coarse filter device, reach to close intact；
(3) combustion engine start, forward type combustion engine air inlet coarse filter device enters duty.
The present invention compared with prior art has the advantage that
1, the installation of forward type combustion engine air inlet coarse filter of the present invention does not affect the properly functioning of combustion engine equipment；
2, it is carried out under in the present invention, each square frame pocket type coarse filter is dismountable；
3, forward type combustion engine air inlet coarse filter device of the present invention, requires design initial resistance ＜ 30Pa according to combustion engine air inlet, uses whole resistance: 100-120Pa；
4, service life: under nominal situation, the present invention can single use 2-3 month, when SR is bigger than normal, cartridge removal on square frame pocket type coarse filter can be got off, use the mild action such as shake, beating to remove the dust stratification on filtrate, when this DeGrain, the filtrate on filter element can be disassembled, being carried out with water, such Comprehensive service life was up to about 12 months；
5, the use of the present invention, assume responsibility for 10 μm
The most oarse-grained filtration, two grades of fine air filters are made to reach preferable using effect and higher filter efficiency, can solve the ineffective situation of combustion engine system brought because of bad environments completely, two grades of precision Filter elements can reach more than 12 months service life；
6, the present invention is not only simple in structure, easy to operate, low cost, can pull down cleaning, reuse during coarse filter dust stratification, and service life is long, and filter effect is obvious, improves air quality, provides high-quality air for gas turbine, decreases shutdown, add generating.
