Abstract
The utility model belongs to the technical field of the analytical instrument and particularly relates to a sampling system of an optical analyzer used for online gas analysis. The utility model mainly comprises a filter, a ball valve and a sampling tube which are orderly connected from top to bottom. The utility model can remove liquid and solid impurities well, the removed impurities can automatically flow back to a process pipeline and does not need termly discharging, and the utility model can ensure that the optical instrument can be operated for long and is not polluted.
Description
Technical field: the utility model belongs to technical field of analytical instruments, is specifically related to a kind of optic analytical instrument (ultraviolet absorption method H that is used for online gas analysis
2S analyser and ultraviolet absorption method trace SO
2Analyser) sampling system.
Background technology: the conventional online optic analytical instrument all has sampling system, and it mainly acts on is the liquid or solid-state impurity of removing in the tested process gas.Existing sampling system takes the method for discharging regularly to get rid of the impurity that filters, and brings inevitably because the contaminated problem of instrumental optics system that does not have discharging in time to cause.Make to measure and be difficult to permanent realization.
Summary of the invention: the purpose of this utility model is a kind of sampler that is used for online gas analysis of design, can remove liquid state and solid impurity well, remove the impurity that gets off and flow back to process pipe automatically, often not need discharging regularly, guarantee that optical instrument moves for a long time, not contaminated.
The utility model mainly comprises: filtrator, ball valve, stopple coupon, the three links to each other from top to bottom successively.
General embodiment stopple coupon sample tap is the inclined-plane; Filtrator generally comprises cavity, screen layer and filtering layer.
The utility model mainly utilizes the method for physics, remove moisture and impurity in the sample gas, sample gas is at middle process earlier stopple coupon, ball valve and filter cavity reduction of speed, increase contact area through wide-meshed screen again, make moisture and big solid impurity be adsorbed interception, when hydrogenesis becomes to reach big water droplet, under action of gravity,, simultaneously solid impurity is washed away down toward dirty.The first half filling activated charcoal of filtrator, the impurity that absorption is not blocked reaches the purpose that purifies sample gas.Filtrator is divided into two halves up and down for the ease of filling and cleaning, uses bolted on connection.In order to make the impurity that is removed past dirty under action of gravity, can adopt suitable mounting means.In order to remove the solid steam of similar sulphur steam and so on, can take to mix heat in its outside or mix insulation temperature control measures such as cold, to enlarge its scope of application.
Description of drawings: accompanying drawing 1 is the structural representation sketch of the utility model embodiment, in the accompanying drawing 1, and the 1-filtrator; The 2-screen layer; 3-filtering layer (activated charcoal); The 4-cavity; The 5-ball valve; The 6-stopple coupon; The 7-wireway.
Embodiment:, the utility model is described in detail below in conjunction with accompanying drawing 1 and embodiment.
Embodiment:
Sampler mainly comprises stopple coupon 6, ball valve 5 and filtrator 1, enters filtrator 1 after process gas process stopple coupon 6 and the ball valve 5 deceleration sedimentations and filters.Filtrator 1 is formed by connecting by two sections, is made up of screen layer 2, activated carbon filter layer 3, screen layer 2, cavity 4, scalping stratum reticulare 2, cavity 4 respectively from top to bottom.The sample tap of stopple coupon 6 is the inclined-plane, and angle flows to back to process gas, avoids impurity directly to enter stopple coupon 6 under the blow pressure of process gas, is beneficial to the liquid of separating out simultaneously and flows back to process pipe; When being used to keep in repair, ball valve 5 cuts off process gas; Filtrator 1 is removed the impurity in the process gas.7 for removing the wireway of analyser.After combining as a whole, whole device is welded on the equipment pipe.
