Description
Technical field
The utility model relates to screw compression technical fields, and in particular to a kind of helical-lobe compressor air inlet cooling, noise reduction dress
It sets.
Background technique
Helical-lobe compressor inlet duct is the critical component of the helical-lobe compressor, its operation function will have a direct impact on this
The operational efficiency of helical-lobe compressor and safety with by property.
Inlet duct structure how is improved, is always ability to realize the raising of the capacity and efficiency of compressor
The direction of field technique personnel research；And helical-lobe compressor is in the process of running, is often accompanied by noise pollution.
Summary of the invention
To solve the above problems, design is closed the utility model proposes a kind of helical-lobe compressor air inlet cooling, denoising device
Reason, structure is simple, and using this device, the capacity of compressor improves 2-3%, and efficiency improves 2-3%, realizes energy-efficient purpose；Together
When can be effectively reduced the noise intensity of compressor.
The technical solution of the utility model includes:
A kind of helical-lobe compressor air inlet cooling, denoising device, it includes cabinet；The bottom of box side be provided with into
Conductance air port, the bottom of box other side are designed to that inclined-plane, top of the box are provided with entrance, and entrance is opposite with inclined-plane, if entrance by
The dry funnel-form air inlet that is evenly arranged with collectively forms, and funnel-form air inlet includes the bucket of taper and is connected with the lower port of bucket
Tail pipe, the upper end of bucket is fixed on top of the box, and the upper port of bucket passes through outside cabinet connection cabinet, and tail pipe protrudes into cabinet；
Sound-insulating covering is vertically installed between entrance and air inlet air guide hole, sound-insulating covering top and two sides are fixedly connected with cabinet, every
There are gaps between sound baffle bottom and cabinet；The cabinet exterior is additionally provided with one layer of acoustical cotton；The air inlet wind-guiding
Mouth connect compressor air inlet access port.
Helical-lobe compressor sucks gas by air inlet cooling, denoising device, and gas is from the upper end of the bucket of funnel-form air inlet
Mouth air inlet, enters cabinet by the tail pipe of funnel-form air inlet, in intake process, due to the variable diameter of funnel-form air inlet, makes
Gas is obtained in flow process, air velocity is improved, increases the pressure of gas, to make gas realize temperature decline, together
When intake air temperature decline, improve unit volume in air molecular density, the quality of unit air is promoted, to improve compression
The unit time extraction flow of machine promotes the efficiency of compressor, and then realizes energy-efficient purpose；And by the test of our company, make
The capacity of compressor is set to improve 2-3% with the device, efficiency improves 2-3%.
In the intracorporal sound-insulating covering of case, refraction, reflection, sound-absorbing are effectively relieved for bottom of box inclined design and design
The noise that box house air-flow generates designs the acoustical cotton of wall outside the enclosure, the equipment noise further decreased, so that noise is strong
Degree is controlled.
Above-mentioned technical proposal is improved further and is refined, the quantity and funnel-form of the funnel-form air inlet
The length of air inlet tail pipe is according to the of different sizes of compressor host, the different selections of pressure.
Above-mentioned technical proposal is improved further and is refined, the acoustical cotton with a thickness of 30mm.
The utility model advantage is that rationally, structure is simple for design, and using this device, the capacity of compressor improves 2-3%,
Efficiency improves 2-3%, realizes energy-efficient purpose；It can be effectively reduced the noise intensity of compressor simultaneously.
