Description

一种腔式气体正负压保护装置
技术领域
本发明涉及一种保护装置，具体涉及一种腔式气体正负压保护装置。
背景技术
在大中型沼气工程中关键的设施是厌氧发酵罐，甲烷气体就在发酵罐中产生。厌氧发酵罐在正常运行过程中，受进出料、外界气温变化以及用气系统波动的影响，罐内压力经常波动。为了防止罐内压力波动造成罐体失衡或涨裂，必须设置正负压保护装置进行保护。目前常用的正负压保护装置有机械式、水封式等几种。机械式保护装置存在易腐蚀、寿命低等不足。CN102199524A公开了一种“沼气发酵用水封式正负压保护器”，它是在主发酵罐与储气罐之间设置两个密封罐、在储气罐与外界打球之间也设置两个密封罐。当主发酵罐内的压力达到设定上限时，开始向储气罐内泄压，当储气罐内压力也达到设定上限时，开始向大气泄压。当主发酵罐内的压力低于设定下限时，储气罐向主发酵罐内补充压力，当储气罐内压力不足时，大气向储气罐及主发酵罐内补充，从而对主发酵罐进行正负压保护的目的，保证主发酵罐内压力始终处于正常工作范围内，保证主发酵罐的正常温度工作。该保护器克服了机械式保护装置易腐蚀、寿命低等不足，但存在占地面积大，低温环境冻结、投资和管理费用高等问题。
发明内容
本发明的目的是克服现有技术的不足，而提供一种不受天气影响，不受地域条件限制，不受介质的挥发反复添加，安装检修方便，制作成本低、使用寿命长的腔式气体正负压保护装置。
本发明的目的是这样实现的：一种腔式气体正负压保护装置，包括设置有沼气进气孔的罐体，其特征在于：在罐体上还设置有负压进气孔，负压进气孔的内侧设置有内腔板、内塔簧和内挡板，中部设置有外腔板和支架，外侧设置有外塔簧和外挡板，螺杆依次穿过内挡板、内塔簧、内腔板、外腔板、支架、外塔簧和外挡板，两端通过螺母旋紧。
所述内腔板通过定位销活动定位在负压进气孔内侧的罐体上，中部设置有正压泄气孔，内腔板与罐体之间设置有密封圈。
所述支架穿过负压进气孔固定在内腔板的外侧，外腔板通过定位销活动定位在支架上。 
所述罐体为圆柱形或方形。
所述罐体采用不锈钢冲压成型或塑料注射成型或玻璃钢注射成型。
本发明装置通过旋转螺母调节塔形弹簧的作用力与设定的沼气临界压力值一致，当罐体内的沼气压力超过设定的临界状态时，罐体内的沼气压力推开外腔板，沼气从泄气口排出，当沼气排出后达到临界值时，外腔板受塔形弹簧的作用关闭。当罐体内的沼气压力低于外界大气压力时，在外界空气压力的作用下，推开内腔板，空气通过进气口进入到罐体内，内外达到平衡后，内腔板在塔形弹簧的作用下关闭。
与现有技术相比，本发明的有益效果为：
1、本发明装置螺杆选用碳钢镀锌螺杆，塔形弹簧选用不锈钢材质，克服了机械式保护装置易腐蚀、寿命低等不足。
2、本发明装置结构简单，构思新颖，制作成本低，安装方便，克服了水封式正负压保护器占地面积大，低温环境冻结、投资和管理费用高等弊端，是大中型沼气工程水封式正负压保护器的替代产品。
