Description

多通道采样装置 Multi-channel sampling device

技术领域 FIELD

[0001] 本发明涉及气体采样,特别涉及多通道采样装置。 [0001] The present invention relates to a gas sampling, and more particularly to a multi-channel sampling device.

背景技术 Background technique

[0002] 多通道采样器可利用多个采样通道实现同时对多个物种进行采样,每个采样通道配一个采样罐,每个采样罐中放置多片采样滤膜及溶蚀器,然后采样罐接入到采样器主机上开始采样,采样完成后取下采样罐更换滤膜及溶蚀器,随后再将采样罐接入主机开始下一个采样周期。 [0002] Multi-channel sample may utilize a plurality of channels sampled simultaneously achieve a plurality of species of samples, each sample channel with a sample cylinder, placed over a sample membrane and dissolve in each sample canister, and the canister then the sampler into the host starts sampling, sampling the canister is removed after the completion of the replacement filter and denuder, then start again the next sampling period of a sampling tank connected to the host. 在这里采样罐作为滤膜及溶蚀器的载体要经常拆卸与安装,要求拆装结构快速、可靠,并且安装后接口处要保证气密性。 Here canister filter and as a support to the denuder removal and installation often requires disassembly fast, reliable, and at the interface after installation to ensure airtightness.

[0003] 目前常见的采样罐结构存在以下几个缺陷: [0003] Currently there are several common defects canister structure:

[0004] 1.由于采样罐是人工手动拆装,为了防止遗漏,在开始采样前软件会自动判断采样罐是否已安装到采样器主机上,一般是通过设置霍尔器件、接近开关、触点开关等电子元件进行判断,不但会带来额外的成本,而且由于采样罐是处在户外环境的,会极大的增加此类电子元件的失效概率从而引发系统误判。 [0004] 1. Since the canister is manually removable, to prevent the omission, the sampling begins before the software will automatically determine if the canister is mounted to the sampler host, typically provided by a Hall device, proximity switches, contacts Analyzing switches and other electronic components, not only extra cost, but since the canister is in an outdoor environment, greatly increases the probability of failure of electronic components such false triggering system. 另外每个采样罐都要走线到采样器主机内,力口大了主机防水防尘的难度及走线布局的复杂性; In addition, each sample can be sampled into the trace host, the host power ports Great difficulty and complexity of the waterproof and dustproof wiring layout;

[0005] 2.采样罐与主机接口处的密封结构简单,采样罐取下后,主机接口完全敞开,容易被水汽、粉尘、扬絮、飞虫等异物侵入到主机气路内,影响气路系统中各器件的寿命,引发不明的采样故障。 [0005] 2. The canister and the sealing structure at the host interface is simple, the canister is removed, the host interface is fully open, easily invaded vapor, dust, Yang Xu, insects and other foreign matter into the main air passage, the air passage Effect life of each system device, causing failure of unknown samples.
