Description

The external sourdine of PSA Nitrogen plant

Technical field

The utility model relates to silencing equipment technical field, is specifically related to the external sourdine of PSA Nitrogen plant.

Background technology

PSA Nitrogen plant is that pneumatically is as starting material, adsorb oxygen molecules inside pressurized air is removed, nitrogen uses by being stored into gas-holder, adsorber, in operational process, from adsorber expellant gas with certain pressure, can produce very large noise when vent valve discharges, cause the noise pollution problem in Working environment, also occurred the sourdine on many PSA Nitrogen plants on the market, but its soundproof effect is poor, can produce larger noise pollution.

Utility model content

The deficiency that the utility model proposes for background technology, has researched and developed the external sourdine of a kind of PSA Nitrogen plant, its object is to: provide a kind of structure simple, the Nitrogen plant sourdine that soundproof effect is good.

Technical solution of the present utility model:

The external sourdine of PSA Nitrogen plant, comprise PSA Nitrogen plant, vapor pipe, it is characterized in that: also comprise noise-abatement equipment, described noise-abatement equipment is connected with PSA Nitrogen plant by pipeline, noise-abatement equipment comprises silencing pot, tight loop, sourdine, sound insulation net, silencing pot is enclosed within sourdine by tight loop, and sound insulation net is arranged in silencing pot.

Described vapor pipe is venting port bend pipe down.

Described tight loop is fastened by bolts on silencing pot.

Described sound insulation net is perpendicular type net.

Described sound insulation net material is stainless steel.

The beneficial effects of the utility model: the utility model structure is simple, and cost performance is high, excellent noise reduction effect, greatly reduces noise pollution, are convenient to produce, are applicable to apply on a large scale.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Fig. 2 is silencing pot diagrammatic cross-section in the utility model.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

As depicted in figs. 1 and 2, the external sourdine of PSA Nitrogen plant, comprise PSA Nitrogen plant 1, vapor pipe 2, also comprise noise-abatement equipment, noise-abatement equipment is connected with PSA Nitrogen plant 1 by pipeline 3, noise-abatement equipment comprises silencing pot 4-1, tight loop 4-2, sourdine 4-3, sound insulation net 4-5, silencing pot 4-1 is enclosed within sourdine 4-3 by tight loop 4-2, sound insulation net 4-5 is arranged in silencing pot 4-1, vapor pipe 2 is venting port bend pipe down, tight loop 4-2 is fastened on silencing pot 4-1 by bolt 4-4, and sound insulation net 4-5 is perpendicular type net, and sound insulation net 4-5 material is stainless steel.

Concrete use procedure: PSA Nitrogen plant 1 operationally, sound to be passed in the sound insulation net 4-5 that is arranged in silencing pot 4-1 by waste gas further that get rid of by the transmission in sourdine 4-3 interior molecules sieve gap, in sound insulation net 4-5 on collide sound insulation net 4-5 wall sound in transmittance process and successively decrease gradually thus serve noise elimination effect.

To sum up, the utility model accomplishes the end in view.
