Abstract

The utility model provides an ultra silent generator double-layer sound isolation type air inlet system, which comprises a first sound isolation plate, a second sound isolation plate and sound reduction cotton, wherein an air inlet is arranged on the first sound isolation plate, an air outlet is arranged on the second sound isolation plate, the first sound isolation plate and the second sound isolation plate are covered to form a sound isolation door, the inner portion of the sound isolation door is hollow to form an air inlet channel, and the sound reduction cotton is added in the air inlet channel. The ultra silent generator double-layer sound isolation type air inlet system uses a pipeline type air inlet structure, combines a double-layer sound isolation mode, and adds the sound reduction cotton, can spread the noise in a case through the air inlet channel at last during the spread process, eliminates a large part of the noise through the sound reduction cotton during the spread process in a pipeline, and is excellent in noise reduction effect.

Description

The double-deck sound-insulating gas handling system of a kind of super-silent generator set
Technical field
The utility model relates to the generator gas handling system, relates in particular to the double-deck sound-insulating gas handling system of a kind of super-silent generator set.
Background technique
As everyone knows, noise is quite serious to people's harm, can cause the absent minded of people, and mood is irritated, and fatiguability is slow in reacting, and degradation under workmanship, severe patient also can cause the deaf health pathology that waits, and even cause accident.The noise of general diesel generating set is more than 80DB, and according to the working principle of fuel engine power generation unit, the generation of its noise is very complicated.Divide from the reason and the position that produce, the noise of fuel engine power generation unit can comprise following a few part: 1. the noise of discharging fume; 2. mechanical noise; 3. combustion noise; 4. cooling fan and air draft noise; 5. air intake noise; 6. generator noise.Come minute can to conclude following three kinds of noises according to path of propagation: 1. internal-combustion engine smoke evacuation noise; 2. inflow noise; 3. air draft noise.
Tradition mute power generator group is all to adopt the direct air inlet of louvre type, and in the time of air inlet, noise can directly penetrate out from the louvre ventilation mouth, and noise is large.
Summary of the invention
For overcoming defects, the purpose of this utility model is to provide a kind of simple in structure, double-deck sound-insulating gas handling system of super-silent generator set that can effectively reduce the suction port noise.
For achieving the above object, the technical solution of the utility model is:
The double-deck sound-insulating gas handling system of a kind of super-silent generator set, it comprises the first insulation board, the second insulation board, silencing cotton, the first insulation board is provided with an intake grill, the second insulation board is provided with an exhaust outlet, the first insulation board and the second insulation board fasten and form a soundproof door, described soundproof door inner hollow forms a gas-entered passageway, adds silencing cotton in gas-entered passageway.
Described the first insulation board fastens by screw and is fastened on the second insulation board, forms soundproof door.
Described intake grill is positioned at the upper right of the first insulation board, and described exhaust outlet is positioned at the left bottom of the second insulation board.
The usefulness of technique scheme is:
The utility model adopts the pipe type air inlet structure, and in conjunction with double-deck sound insulation mode, install at last silencing cotton additional in pipeline, like this, the noise of cabinet inside must just can disseminate out by gas-entered passageway in the process of propagating at last, and noise a big chunk noise in the process that pipe interior is propagated has been eliminated by silencing cotton, excellent noise reduction effect.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the first insulation board structural representation of the present utility model.
Fig. 3 is the second insulation board structural representation of the present utility model.
Wherein, 1. the first insulation board 2. second insulation board 3. silencing cotton 4. intake grill 5. exhaust outlet 6. gas-entered passageways.
Embodiment
Embodiment
The double-deck sound-insulating gas handling system of a kind of super-silent generator set as shown in Figure 1, it comprises the first insulation board 1, the second insulation board 2, silencing cotton 3, the upper right of the first insulation board 1 is provided with an intake grill 4, the left bottom of the second insulation board 2 is provided with an exhaust outlet 5, the first insulation board 1 fastens by screw and is fastened on the second insulation board 2, forms soundproof door, the soundproof door inner hollow, form a gas-entered passageway 6, add silencing cotton 3 in gas-entered passageway 6.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technological scheme.
