Abstract

本实用新型涉及的是气体的喷散装置，主要是由旋流器、套筒、定位环和联接法兰构成，其主要特点就是旋流器上开有切向孔，使气体在旋流器中产生旋流，从而达到将气体喷散的目的，本实用新型的气体喷散装置结构简单、设计合理、用途广、实用性强，喷散效果好，不仅可以用于燃烧装置的气体燃烧，而且还可以用于输送带粉状物料。

Description

气体喷散嘴
本实用新型涉及的是气体的喷散装置。
现有的气体喷咀大多为简单的孔咀，气体不能完全被喷散，在一些情况如燃烧，就难于实现与空气的均匀混合与充分燃烧。
本实用新型的目的就是设计一种新型气体喷散咀，使气体能充分喷散。
本实用新型的气体喷散咀是利用气体在喷咀中产生的切向和轴向速度合成形成中空的圆锥而将气体喷散的原理，同时对喷口的横截面积的匹配进行了选择，使之能适用各种用途的需要。
本实用新型的详细内容和实施方案参见附图描述如下：
本实用新型的喷散咀主要是由旋流器（1）、套筒（2）、定位环（3）和联接法兰（4）组成，如图1所示旋流器（1）装在套筒（2）内一端，旋流器（1）为一端封闭、另一端开口的杯状，开口端为气体的喷口，在旋流器的筒壁上开有切向通道。本实用新型的旋流器上的切向通道是由筒壁上的1－6个环，每个环上开有6－12个切向孔构成，且这些切向孔的横断面积的总和为旋流器（1）内腔喷口横断面积的0.8－2倍，喷散锥角为30°－100°，在本实用新型中，旋流器（1）的轴向位置可以根据需要进行调整，气体喷散咀可以用普通钢板焊制或用塑料制成，如用于燃烧装置时用普通钢板制，在冷态下使用时可用塑料制成。
按照附图所示的实施方案，把用普通钢板焊制的气体喷散咀安装在颜氏燃烧器上，用于喷散天然气，气体从图1的右端进入，沿套筒（2）和旋流器（1）的夹层进入旋流器（1）的切向孔中，气体经过切向孔后因压降而增速，使之在旋流器（1）的内腔中旋转，并从内腔的喷口喷散成中空的锥形，喷散后的天然气进入燃烧器后，在其中组织燃烧。
按照本实用新型制做的燃烧器，结构简单，实用性强，气体喷散效果好，用途广、设计合理。
图1表示气体喷散咀的剖面图。其中（1）旋流器，（2）套筒，（3）定位环，（4）联接法兰。
图2表示旋流器的结构图。
图3表示图2的A－A剖面。
