The air pipe is composed of three layers of shell bodies, namely an outer cover and two layers of pore plate covers. The noise reducing cotton is filled into all the shell bodies and the fans are arranged inside the air pipe. The air exchanging and noise reducing device is characterized in that the pipe diameter of an inner cavity of the air pipe gradually increases from an air inlet to an air outlet, the air outlet of the air pipe is arranged to be in the shape of a horn mouth, fan blades are arranged at the two ends of a motor of each fan, the fan blades facing the air outlet are connected with rotation shafts of the motors, the fan blades at the other end are connected with outer shells of the motors and rubber partition plates are further evenly arranged on the inner pipe wall of the air pipe. According to the air exchanging and noise reducing device, expansion-type design is adopted in the structure of the inner cavity of the air pipe, a plurality of double-fan-blade fans are arranged inside the air pipe, air flow is divided in a multi-fan and low-rotation-speed mode, air flow in the inner cavity of the air pipe is made to rotate spirally so as to generate the vortex noise reducing effect, the design that the double layers of micro-punch pore plates are connected in parallel is adopted in the inner wall of the air pipe and the noise reducing cotton is arranged at intervals in a filling mode, so that noise is further absorbed and reduced and the noise reducing function of the air exchanging device is greatly enhanced.
Description
Technical field
The utility model relates to a kind of marine drilling ventilation equipment, is specifically related to a kind of marine drilling platform ventilation denoising device.
Background technique
In marine drilling operation process, when drill bit tops the oil sand, the rock gas in stratum can be up along well, is easier to the situation that causes drill platform to assemble a large amount of rock gases around, due to the existence of the uncertain factors such as static, be easy to cause that fire even explodes.In order to keep ventilating, by being gathered in drill platform rock gas around, discharge fast, so drill platform needs many large-scale air interchangers.Noise is larger in the course of the work for the air interchanger that we use at present, generally can surpass 135dB, and driller works for a long time under this strong noise, can produce agitation, has palpitation, the bad reaction such as headache, has a strong impact on healthy.At present also exist some to there is the large-scale air interchanger of certain Noise Reduction, but mostly, because structural design is unreasonable, noise reduction is undesirable, and production and user cost higher, therefore, in industry, need a kind of marine drilling air interchanger cheaply with obvious Noise Reduction badly at present.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of above prior art, and a kind of marine drilling platform ventilation denoising device proposed, this device has adopted expansion design to airduct inner-cavity structure, a plurality of Dual-blade blower fans are set in airduct, adopt multi fan, slow-revving mode is by airflow diversion, airduct inner chamber flow spiral is rotated, produce eddy current soundproof effect, airduct inwall adopts double-deck microperforated panel Parallel Design, the cotton of eliminating the noise is filled at interval, sound is further absorbed, subdue, this device combines expansion, vortex type, power absorption formula, the noise elimination modes such as crack cellular type, greatly improved the decrease of noise functions of this air interchanger.
The utility model scheme is achieved by the following technical measures:
A kind of marine drilling platform ventilation denoising device, comprise airduct, noise elimination cotton, blower fan, airduct consists of outer cover and double-deck orifice plate cover, between outer cover and double-deck orifice plate cover and between the inner cover of double-deck orifice plate cover and outer cover, be all filled with the cotton of eliminating the noise, blower fan is fixed in airduct pipe by strut, its feature is that airduct inner chamber caliber becomes large gradually by intake grill to exhaust outlet, airduct exhaust outlet is set to horn mouth shape, the motor two ends of blower fan are equipped with flabellum, the rotatingshaft that connects motor towards the flabellum of exhaust outlet, the flabellum of the other end connects motor housing.
The blower fan quantity of installing in above-described airduct pipe is more than or equal to two.
On the inner tubal wall of the above airduct, be also evenly provided with rubber separator.
Above-described airduct is outer cover and three layers of shell construction of double-deck orifice plate cover, two microperforated panels formation that is connected in parallel for double-deck orifice plate cover.
The beneficial effects of the utility model are: this device has mainly been gathered expansion, vortex type, power absorption formula, four kinds of noise elimination modes of crack cellular type and carried out noise abatement, airduct inner-cavity structure has adopted expansion design, by intake grill, to exhaust outlet inner chamber caliber, become gradually large, produce expansion erasure effect, exhaust outlet is set to horn mouth shape, can further reduce noise; A plurality of Dual-blade blower fans are set in airduct, be preferably four, before and after the motor of each blower fan, all there are two flabellums, flabellum towards exhaust outlet one end is power blade, the other end flabellum is passive flabellum, adopt multi fan, slow-revving mode by airflow diversion, airduct inner chamber flow spiral is rotated, produce eddy current soundproof effect; Airduct inwall (being double-deck orifice plate cover) adopts double-deck microperforated panel Parallel Design, effectively reduces noise; Each interlayer of wind pipe wall, every filling the cotton of eliminating the noise, is also evenly provided with rubber separator on inner tubal wall, sound is further absorbed, subdued.This device has improved the decrease of noise functions of air interchanger greatly, has avoided driller because noise is excessive, to make health come to harm, and multi fan, the energy-saving and environmental protection more of slow-revving mode, has higher application value.
