Wherein, two side connecting plates are used for connecting and fixing the upper cover plate and the lower cover plate. A plurality of circular air cylinders 3, 4 and 5 are arranged between the upper cover plate and the lower cover plate and are combined and fixed through the upper cover plate, the lower cover plate and the side connecting plate. The air chamber upper cover plate 1, the air chamber lower cover plate 2 and the plurality of circular air cylinders 3, 4 and 5 are sealed through sealant.

The air passage channel inside the closed air chamber is isolated by a sealing ring.
In an exemplary embodiment of the invention, as shown in fig. 4, the spacer sleeves 6, 7, 8 may comprise a straight sleeve 110 and a disc-shaped protrusion 111 at its upper end. The distance sleeves 6, 7, 8 may be integrally formed or formed by movably connecting a straight sleeve 110 and a disc-shaped protrusion 111. The disc-shaped protrusion 111 may have a circular truncated cone structure. Preferably, the diameter of the disc-shaped protrusion 111 is larger than that of the straight sleeve 110. As shown in fig. 4, it is further preferred that the spacer sleeves 6, 7, 8 may be of mushroom-like construction. 5-7 cyclone guide grooves F are uniformly arranged on the disc-shaped bulge 111 from the center to the periphery in sequence. More preferably, 6 cyclone guide grooves F are formed.
The cyclone guide groove F is a gas guide groove for guiding gas flow to flow along the circumferential direction of the circular closed gas chamber, and is the key point of the invention. Preferably, the cyclone guide grooves F may be arranged in a straight line shape, or in a curved shape, or in a spiral shape on the disc-shaped protrusion 111 in a circumferential tangential direction; or arranged tangentially along the air chamber in a spiral direction. Further preferably, the cyclone guide groove F may be, for example, a half groove having a U-shaped cross section; or may be a pilot hole or a pilot tube. That is, all structures inside the air chamber that can make the air inside the air chamber perform spiral motion are within the protection scope of the present invention.
In an exemplary embodiment of the present invention, as shown in fig. 4, a groove G is further provided on the outer peripheral side of the disc-shaped protrusion 111. The provision of the groove G has two functions: 1, used for reducing the exhaust resistance of the cyclone guide groove F; 2, for discharging the impurities existing in the upper gap of the disc-shaped protrusion 111.
The composite air chamber gas dryer adopts a composite air chamber framework, and air chambers all adopt a circular air cylinder assembly type structure, wherein the spacer sleeves 6, 7 and 8 can be integrally designed with the cyclone guide groove F, so that the production process of the product is greatly simplified, and the reliability of the product is improved. According to the invention, the outside of the first sleeve 6 is communicated with the outside of the second sleeve 7 through a chamber communication pipeline D in the chamber upper cover plate 1. The inner side of the second separation sleeve 7 is communicated with the outer side of the third separation sleeve 8 through an air chamber communication pipeline E positioned in the air chamber upper cover plate 1.
The flow process of the sample gas to be monitored in the composite gas chamber gas dryer is as follows:
the sample gas to be monitored enters the first closed gas chamber A through the gas inlet nozzle 9, and the cyclone gas nozzle 11 is arranged at the position of the gas inlet nozzle 9, so that the entering sample gas is accelerated through the cyclone gas nozzle 11, the gas entering the composite gas chamber gas dryer is accelerated to be sprayed to the inner wall of the first separation sleeve 6 and is condensed inside the first separation sleeve 6. The gas after the primary cooling is led out along the lower part of the first separation sleeve 6, flows upwards along the air outlet direction of the first separation sleeve 6 under the suction action of the air outlet nozzle, and can not continue upwards along the inner wall of the first separation sleeve 6 but is guided to the outer wall of the first separation sleeve 6 under the blocking of the condensation reflection cover 17.
That is to say, the gas reaches the upper part of the first closed air chamber A after being turned back by the condensation and reflection cover 17, and the gas after condensation and dehydration enters the outside of the second sleeve separating sleeve 7 of the second closed air chamber (dehydration and absorption air chamber) B through the cyclone guide groove F of the first sleeve separating sleeve 6 and then through the air chamber communication pipeline D in the air chamber upper cover plate 1. Then, the entering gas enters through the cyclone guide groove F on the second separation sleeve 7 and rotates along the inner wall of the second closed gas chamber B so as to achieve the purpose of fully combining with the dry silica gel to effectively adsorb the water vapor in the gas. The fully adsorbed gas enters a third closed gas chamber C (fine filtering gas chamber) through a communication pipeline E of the upper cover plate 1 of the gas chamber. Liquid water drops generated after condensation by the condensation reflecting cover 17 and dust contained in the sample gas are deposited in a groove of the water storage cock at the lower part of the air cavity and are discharged through a sealing rotary cover 19 at the bottom of the second separation sleeve 7. In addition, the dry silica gel in the second closed air chamber B can be replaced and filled through the sealing screw cap 19 at the bottom of the second partition sleeve 7.
The sample gas dried by the second separation sleeve 7 enters the outside of the third separation sleeve 8 of a third airtight gas chamber (fine filtering gas chamber) C through the adapter 12 and the gas chamber communication pipeline E, and the gas of the third airtight gas chamber C enters the inside of the third separation sleeve 8 after being filtered by the sintered filter element 14 below the third separation sleeve 8 and then is discharged through the exhaust nozzle 10 above. When the gas flows above the separating sleeves 6, 7 and 8, the cyclone guide grooves F for guiding the gas to flow along the tangential direction of the inner wall of the circular gas cylinder are formed above the separating sleeves, so that the gas can be used for improving the flowing state of the gas in the closed gas chamber. The adapter 12 is used for fixing the second spacer and communicating the air path.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
