Abstract

本实用新型公开了一种多层隔热保温直吹管，包括煤粉喷管(1)、热风管(2)、捣打料(3)和套管(4)，煤粉喷管(1)和热风管(2)相接通，在套管(4)内壁和捣打料(3)之间设置有耐火毡(6)。在所述在套管(4)内壁和耐火毡(6)之间还设置有耐高温涂料层(5)。因耐火毡多为纤维制品，化学稳定性好，具有低导热率、绝热保温的功能，故此，在套管内壁和捣打料之间设置耐火毡，能进一步隔热，从而降低直吹管的外表温度。因耐高温涂料有粘合力强，使其与套管内壁紧密结合在一起，降低了热量的散发，故此，克服了发红、漏风等普遍存在的问题，使能量损耗大幅度降低，为钢铁企业节约了大量焦炭，增加了企业经济效益。

Description

一种多层隔热保温直吹管
技术领域
本实用新型涉及一种炼铁高炉进风装置中的直吹管，属于高炉炼铁设备领域。
背景技术
在高炉炼铁过程中，需要将热风炉中产生的高温热气送到高炉中，而高炉进风装置就是专门设置的进风通道装置，直吹管属进风装置的一部分。
目前，在国内冶金行业炼铁厂，由热风总管、热风围管、风口送风装置及风口等组成的高炉送风装置中，高炉风口送风装置是其中的薄弱环节，而且目前国内高炉风口送风装置普遍存在外表温度高、发红、漏风、使用寿命短，因外表温度高造成热能损失过大等诸多弊病，难以满足高炉冶炼对送风装置的使用要求。
实用新型内容
本实用新型需要解决的技术问题是提供一种隔热好、外表温度低的直吹管。
为解决上述技术问题，本实用新型所采取的技术方案是：
一种高保温直吹管，包括煤粉喷管、热风管、捣打料和套管，煤粉喷管和热风管相接通，在套管内壁和捣打料之间设置有耐火毡。
作为本实用新型的改进，在所述在套管内壁和耐火毡之间还设置有耐高温涂料层。
由于采用了上述技术方案，本实用新型所取得的技术进步在于：
1、耐火毡多为纤维制品，化学稳定性好，具有低导热率、绝热保温的功能，故此，在套管内壁和捣打料之间设置耐火毡，能进一步隔热，从而降低直吹管的外表温度。
2、在套管内壁上设置有耐高温涂料层，因耐高温涂料有粘合力强，使其与套管内壁粘连在一起，降低了热量的散发，故此，克服了发红、漏风等普遍存在的问题，尤其是将其表面温度由原来的280℃-350℃范围降到50℃-80℃范围内，使能量损耗大幅度降低，为钢铁企业节约了大量焦炭，增加了企业经济效益。
附图说明
图1是本实用新型直吹管的结构简图。
其中：1、煤粉喷管；2、热风管；3、捣打料；4、套管；5、耐高温涂料层；6、耐火毡。
具体实施方式
下面结合附图对本实用新型做进一步详细说明：
图1中，本实用新型的直吹管通常包括煤粉喷管1、热风管2、捣打料3和套管4.套管4内圆周上粘附有捣打料3，中空部分为热风管2，热风管2的一端接热风围管，另一端接高炉，用于给高炉供热风.煤粉喷管1一端与热风管2接通，用于向热风管2中喷煤粉.自套管4内壁到捣打料3之间依次设置了耐高温涂料层5和耐火毡6.制作时，将耐高温涂料JLGW-A涂在套管4内表面(实施例中采用石家庄巨力科技有限公司生产的JLGW-A耐高温涂料)，晾干后，根据套管4内粘附耐高温涂料层5的结构，铺设耐火毡6，再用隔热保温耐火材料进行捣打形成捣打料3(实施例中采用石家庄巨力科技有限公司生产的JLGR-B隔热保温耐火材料)，从而制成成品.
