Description

A kind of filtrate is filled

Technical field

This utility model belongs to gas detection technology improvement areas, more particularly to a kind of filtrate is filled.

Background technology

Zero gas generator is mainly atmosphere quality monitoring system and provides sufficiently stable zero gas of clean dry.With one Sequence of chemical eliminating machine by washing and reaction conversion chamber, can efficiently remove the specific gas in air, such as：SO2, CO, O3, NO, NO2 and HC etc., realizes providing zero clean gas.Equipped with the air compressor machine with functions/drying and desiccant, realize providing enough pressure, Flow, and dew point is low（＜ -15 DEG C）Zero gas.It is to ensure each analyser zero point correction, gas dilution accuracy and stability Premise.

Wherein, relative to NO2, as NO is not easy to be tightly held by activated carbon, so NO is changed into using pula phenanthrene filtrate NO2, then uses activated carbon adsorption again.

Pula phenanthrene filtrate is by potassium permanganate appendix on alumina carrier, due to being loose structure, so water suction Property it is stronger, during assembling test find, air presses gas out through pula phenanthrene after dew point rise nearly 10 DEG C, explanation Moisture in the phenanthrene of pula is more, in order to not affect the oxidation effectiveness of pula phenanthrene filtrate, needs to be dried pula phenanthrene filtrate Process, but due to the chemical property of pula phenanthrene filtrate, which uses temperature below 50 DEG C, otherwise surface blackening is oxidized, and loses Its effect, so needing to find the pula phenanthrene drying process of room temperature and simplicity.

Description of the drawings

Fig. 1 is the structural representation that the filtrate that this utility model embodiment is provided is filled.

Specific embodiment

Reference：The first sealing rings of 102- are covered on 20- body 30- filtrate 50- elbow trachea 101- 103- springs 104- the first drainage screen 105- the first filter cotton 401- bottoms 402- the second sealing ring 403- spacer rings 404- the second drainage screen the second filter cottons of 405-.

Fig. 1 shows that the filtrate that this utility model is provided is filled, the filtrate fill include cover assembly, body 20, filtrate 30 and Bottom component, the cover assembly are covered on one end of the body 20, and the bottom component is covered on the another of the body 20 One end, the filtrate 30 are respectively equipped with elbow trachea 50 in the body on the cover assembly and lower cover component.

The cover assembly includes that lid 101, the first sealing ring 102, spring 103, the first drainage screen 104 and first are filtered Cotton 105, in the upper lid 101, first sealing ring 102 contacts the one of the spring 103 to first sealing ring 102 End, the first drainage screen 104 described in another end in contact of the spring 103, first drainage screen 104 contact described first and filter Cotton 105.

The bottom component includes that bottom 401, the second sealing ring 402, spacer ring 403, the second drainage screen 404 and second are filtered Cotton 405, second sealing ring 402 are located in the bottom 401, the second sealing ring described in the end thereof contacts of the spacer ring 403 402, the second drainage screen 404 described in another end in contact of the spacer ring 403, second drainage screen 404 contact second mistake Filter pulp 405.

The body 20 adopts lucite tube.

First sealing ring 102 and the second sealing ring 402 are O-ring seals.

Zero gas generator has gas outlet dew point low（<-15℃）, gas outlet flow is big, without dusty gass（SO2、CO、 O3, NO, NO2 and HC etc.）The features such as, the exit gas with Zero gas generator designs the general of low temperature as source of the gas with reference to some filtrates Draw luxuriant and rich with fragrance drying process.Exported under room temperature using Zero gas generator and the low gas of dew point is dried place to 3 tank pulas phenanthrene filtrate Reason.Air compressor machine gas dew point out is -30 DEG C or so, through Zero gas generator, removes SO2, CO, O3, NO, NO2 and HC etc., Exit gas dew point is -20 DEG C or so, into 3 parallel branch gas circuits, is silica gel filtrate first, followed by treats in branch air path The pula phenanthrene filtrate of process, is finally activated carbon.For during the enough stops in the phenanthrene filtrate of pula of the clean gas of guarantee drying Between, and having enough substantial amounts of clean dry gas, front end Zero gas generator outlet pressure is set to 0.15MPa, gas outlet stream Measure as 10L/min；To ensure there are enough contacts between air-flow and filtrate, filtrate is placed in filtrate tank, as shown in figure 1, bottom Portions part material from bottom to top（Base-O-ring-spacer ring-drainage screen-filter cotton-filtrate）, upper cover part part is from bottom to top Material（Filtrate-filter cotton-drainage screen-spring-O-ring-upper lid）.Filtrate is loaded：By the spacer ring of drying tube white, mistake Filter screen, filter cotton are sequentially loaded in drying tube, are loaded appropriate filtrate in drying tube with ladle, are attached to lid spiral shell on drying tube Stricture of vagina position, places into filter cotton, drainage screen and spring after installing, ought be pressed onto with palm pressing spring and be flushed with the mouth of pipe, then use belt Spanner tightens lid, it is ensured that air-tightness.

Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
