Description
Technical field
The utility model relates to a kind of diesel generating set tail gas smoke and dust treatment device.
Background technique
At present, the tail gas output unit of large-sized diesel generator set, do not possess the smoke and dust treatment function, cause diesel generating set when work, include a large amount of soot dust granules in the tail gas of being discharged, formed livid dense smoke, if with its direct discharging, can not satisfy environmental requirement at ordinary times, can not satisfy the pseudo-reload request under the wartime special occasions, therefore, increase the smoke and dust treatment function should for the tail gas output unit of diesel generating set.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art exactly, and a kind of diesel generating set tail gas smoke and dust treatment device is provided.This device can solve the emission pollution problem of diesel generating set, makes compliance with environmental protection requirements.
The purpose of this utility model realizes by following technical proposals, diesel generating set tail gas smoke and dust treatment device of the present utility model comprises a housing, this housing has a suction port that is connected with the smoke evacuation output tube of diesel generating set and an air outlet that is connected in the smoke evacuation output pipeline, in housing, be provided with except that oil screen near suction port, be provided with coarse-grain filtering device subsequently, be provided with fine filter near the air outlet, the device of this improvement diesel generating set tail gas flue dust also comprises a differential pressure indicator that is used to detect its internal drag.
Described housing is square, is provided with the end cap of the filter core of the filter core that is used to place coarse-grain filtering device and fine filter at its sidepiece; Also be provided with the cover plate of oil removal filter at its sidepiece.
Described coarse-grain filtering device and fine filter all adopt units folded formula tubular element structural type.
Described oil removal filter is to be made of the mesh material form.
The place can be provided with an induced draught fan in described air outlet.
The concrete function of described structure is as follows:
Suction port is used for being connected with the smoke evacuation output tube of diesel generating set.
Remove oil screen, be used for the oil composition of filtering smoke.
Coarse-grain filtering device is used to capture, filter bigger soot dust granule.
Fine filter is used to filter small soot dust granule, eliminates visible grit, reaches the purification requirement.
End cap is used for fixing filter core thick, fine filter.
Differential pressure indicator is used to detect the resistance of filter core.
The air outlet is used for connecting the smoke evacuation output pipeline, and same coupling, closing element, soft connector are formed an integral body.
The working principle of this device is:
Oil-containing flue dust by the discharge of diesel generating set smoke-ejecting pipe, at first enter the oil screen that removes of this device, behind the filtering oil composition, enter coarse-grain filtering device again, soot dust granule filtering that will be bigger enters fine filter at last again, with small soot dust granule filtering, eliminate visible grit, thereby reach the requirement that purifies flue dust.In order to reduce filter element quantity, reach the purpose that reduces equipment volume, increases filter area, this device has adopted units folded formula tubular element structural type specially, and take all factors into consideration the problem of the aspects such as life-span, cost, filtering effect, material therefor and Unit Installation mode of filtering material, the shell of this device has been made rectangular, like this, not only easily manufactured, also be convenient to the layout of inner filter core unit, make whole device compact efficient, and can reduce the occupation of land space when this device is installed.
Because what this device adopted is layered filtration mechanism, along with flue dust deposits at the filter core table, gas will increase gradually by the resistance of filter core, when the filter core resistance increases to 2 times of resistances (its value can be shown by differential pressure indicator) can change filter core, can be to guarantee generator set because of the too big wasted power of exhaust back pressure increase.In this device when design, structurally taken into full account this point, specially filter core has been designed to the form being convenient to change, and can have changed at any time in the process of device work, and need not shut down.When renew cartridge (thick, smart filter core) more,, filter core is extracted out in housing as long as end cap is opened.Again new filter core is installed in original position and compresses and get final product, whole process is simple and convenient.Because can carry out the replacing of filter core in working order equally, so, can guarantee that can satisfy technical requirement the continuous working life of this device.
Because this device gives the resistance that smoke evacuation increased of generator set less, so, loss to generating set power not quite (can also be installed an induced draught fan at the output terminal of this device as required,, further to overcome this resistance), this device is installed does not influence the proper functioning of generator set, and this point has obtained checking, when basic performance tests and as installed are on probation, after this device was installed, generator set can both reach rated power or peak output output.
This device does not need to increase the personal management, and personnel operate in the lump and can finish by the control of diesel generating set group.
Its important technological parameters:
(1) smoke evacuation smoke intensity: no visible light grit;
(2) smoke evacuation resistance :≤0.03 * 105Pa;
(3) air leakage factor :≤0.1%;
(4) filter core working life (using continuously): 〉=168h (7d);
(5) effective storage life of filter core (airtight): 5 years;
(6) has anti-corrosion function;
(7) boundary dimension mm3:2430 * 1300 * 800.
