Abstract
The invention relates to a blast furnace gas pressure reducing valve sound eliminator which comprises a gas inlet, a gas outlet and a plurality of sections of sound eliminating cavity, wherein a sound eliminating sheet assembly is arranged in each section of sound eliminating cavity; and each sound eliminating sheet assembly comprises multiple groups of sound eliminating sheets. The blast furnace gas pressure reducing valve sound eliminator is characterized in that the sound eliminating sheet assemblies in the adjacent sections of sound eliminating cavity form serrated distribution, i.e. each group of sound eliminating sheet assembly and the horizontal line form a tilting included angle. The invention has good sound eliminating effect and can not affect workers in the production, thereby more favorably improving the production efficiency and being convenient to clean.
Description
Technical field
The present invention relates to a kind of silencing apparatus, relate in particular to a kind of blast furnace gas pressure reducing valve sound eliminator.
Background technique
In blast furnace gas in the past, usually can not be provided with pressure reducing valve sound eliminator, make and in the process of producing, produce very big noise, all bring numerous inconvenience for like this production and life, and existing silencing apparatus can't reach good noise elimination effect, and because the restriction of its structure makes this silencing apparatus have no idea to clean or clean pretty troublesome.
The model utility content
The purpose of this invention is to provide a kind of blast furnace gas pressure reducing valve sound eliminator.
The technical solution used in the present invention is:
Blast furnace gas pressure reducing valve sound eliminator, be provided with multistage noise elimination cavity, be provided with the anechoic sheet assembly in described every section noise elimination cavity, described anechoic sheet assembly includes many group anechoic sheets, anechoic sheet assembly indentation in the described adjacent segment noise elimination cavity distributes, and promptly every group of anechoic sheet assembly and horizontal line are slanted angle.
The slanted angle that every group of anechoic sheet assembly and horizontal line form is 5 °-20 °.
Described anechoic sheet is freely to dismantle anechoic sheet.
The present invention makes silencing apparatus than original similar structure noise elimination better effects if because the anechoic sheet assembly indentation in the adjacent segment noise elimination cavity distributes.
Advantage of the present invention is: good muffling effect, thus can not bring influence better to improve manufacturing efficiency aborning to the workman, it is convenient to clean.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein: 1, noise elimination cavity, 2, the anechoic sheet assembly, 3, anechoic sheet, 4, suction port, 5, the air outlet.
Embodiment
As shown in Figure 1, blast furnace gas pressure reducing valve sound eliminator, comprise suction port 4 and air outlet 5, be provided with four sections noise elimination cavitys 1, be provided with anechoic sheet assembly 2 in every section noise elimination cavity 1, anechoic sheet assembly 2 includes the many groups of anechoic sheets that can freely dismantle 3, and anechoic sheet assembly 2 indentations in the adjacent segment noise elimination cavity 1 distribute, and promptly to be slanted angle α with horizontal line be 15 ° to every group of anechoic sheet assembly 2.When sound when import enters silencing apparatus, the anechoic sheet assembly 2 that sound can distribute by the acoustic streaming formula is organized 2 pairs of sound of anechoic sheet assembly more and is cut down layer by layer, thereby reaches good erasure effect.
Claims (3)
1. blast furnace gas pressure reducing valve sound eliminator, comprise suction port and air outlet, be provided with multistage noise elimination cavity, be provided with the anechoic sheet assembly in described every section noise elimination cavity, described anechoic sheet assembly includes many group anechoic sheets, it is characterized in that: the anechoic sheet assembly indentation in the described adjacent segment noise elimination cavity distributes, and promptly every group of anechoic sheet assembly and horizontal line are slanted angle.
