Description
Technical field
The utility model belongs to gas noise elimination decompression technology field, is specifically related to a kind of underground noise elimination pressure reducer.
Background technology
Cogeneration is to utilize thermal power transfer unnecessary in the production process to be the technology of electric energy.Usually, the noise and the pressure that produce gas during the Boiler Steam emptying are all very big, directly are discharged into the external world and will bring huge pollution to environment, so need earlier these gases to be done the noise elimination reduced pressure treatment.Yet, the most structural design more complicated of existing noise elimination decompressor, and the effect of the decompression of eliminating the noise is not ideal.
The utility model content
The purpose of this utility model: to have noise elimination decompressor complex structural designs, the undesirable problem of noise elimination effect of easing stress now in order solving, and to propose a kind of underground noise elimination pressure reducer.
The technical solution of the utility model: a kind of underground noise elimination pressure reducer, comprise and be arranged at underground one-level noise elimination decompressor, secondary noise elimination decompressor and be arranged at steam exhaust device on the ground, described one-level noise elimination decompressor comprises rubble impact sound reduction hole, and described rubble impact sound reduction hole is provided with air intake and venthole; Described secondary noise elimination decompressor comprises the labyrinth type sand pit, and described labyrinth type sand pit is provided with admission opening, vapor opening and dividing plate, is provided with underground steam passage between described venthole and the admission opening; Described steam exhaust device comprises exhaust passage, and described exhaust passage is communicated with vapor opening.
A kind of underground noise elimination pressure reducer of the present utility model, during use, the gas that produces during with the Boiler Steam emptying inserts air intake, under the effect of rubble impact sound reduction hole medium stone, the noise of gas and pressure obtain preliminary reducing, then, gas after the processing enters the labyrinth type sand pit by underground steam passage, in the labyrinth type sand pit under the effect of grit, gas is after long path, noise and the pressure of gas are further reduced, and at last, noise and pressure meet the gas of discharge requirement from the exhaust passage discharge external world after the process two stages for the treatment of.Such structural design, not only simple in structure, and also the noise elimination effect of easing stress is very desirable.
Further, the sidewall of described exhaust passage is provided with exhaust hole.
The setting of exhaust hole makes that the gas after handling is discharged the external world fast, thereby saves the time of cogeneration, reduces the production cost of enterprise.

Fig. 1 is the main TV structure schematic diagram of the embodiment of a kind of underground noise elimination pressure reducer of the utility model;
Fig. 2 is the plan structure schematic diagram of the embodiment of a kind of underground noise elimination pressure reducer of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of underground noise elimination pressure reducer, comprise and be arranged at underground one-level noise elimination decompressor, secondary noise elimination decompressor and be arranged at steam exhaust device on the ground, one-level noise elimination decompressor comprises rubble impact sound reduction hole 1, and rubble impact sound reduction hole 1 is provided with air intake 10 and venthole 11; Secondary noise elimination decompressor comprises labyrinth type sand pit 2, and labyrinth type sand pit 2 is provided with admission opening 20, vapor opening 21 and dividing plate 22, is provided with underground steam passage 4 between venthole 11 and the admission opening 20; Steam exhaust device comprises exhaust passage 3, and the sidewall of exhaust passage 3 is provided with exhaust hole 30, and exhaust passage 3 is communicated with vapor opening 21.
In the present embodiment, the setting of one-level noise elimination decompressor and secondary noise elimination decompressor, the gas that produces in the time of can realizing the Boiler Steam emptying carries out two-stage and eliminates the noise and reduce pressure.And the setting in rubble impact sound reduction hole 1 mainly utilizes rubble to the inhibition of gas, realize noise elimination and decompression to gas, and the setting in labyrinth type sand pit 2 utilizes mainly grit to the inhibition of gas, realizes noise elimination and decompression to gas.In fact, dividing plate 22 arranges a plurality of, thereby makes the labyrinth type sand pit 2 inner paths that form long path, and is very good to guarantee the noise elimination effect of easing stress.
In addition, the setting of exhaust hole 30 makes that the gas after handling is discharged the external world fast, thereby saves the time of cogeneration, reduces the production cost of enterprise.
During use, the gas that produces during with the Boiler Steam emptying inserts air intake 10, cheat at the rubble impact sound reduction under the effect of 1 medium stone, the noise of gas and pressure obtain preliminary reducing, then, gas after the processing enters labyrinth type sand pit 2 by underground steam passage 4, in labyrinth type sand pit 2 under the effect of grit, gas is after long path, noise and the pressure of gas are further reduced, at last, noise and pressure meet the gas of discharge requirement from the exhaust passage 3 discharge external worlds after the process two stages for the treatment of.
Above-described only is preferred embodiment of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
