[0028] The middle partition 23 divides the liquid reservoir cylinder 21 into two upper and lower chambers. The upper part of the liquid reservoir cylinder 21 is a condensation chamber, and the lower chamber is a liquid storage chamber. A liquid outlet pipe 211 is provided between the condensation chamber and the liquid storage chamber. The liquid outlet pipe 211 is provided on the outer wall of the liquid reservoir cylinder 21. One end of the liquid outlet pipe 211 is connected to the condensation chamber, and the other end is connected to the liquid storage chamber. A stop valve 210 is provided on the liquid outlet pipe 211.

[0029] A cooling water inlet 25 and a cooling water outlet 26 are provided on the top of the head cover plate 22. A spiral cooling coil 24 is provided in the condensation chamber. One end of the cooling coil 24 is connected to the cooling water inlet 25, and the other end is connected to the cooling water outlet 26. An air inlet B27 is provided on one side of the condensation chamber, and an air outlet B28 is provided on the other side.

[0030] A vent valve 29 is provided on one side of the liquid storage chamber, and a liquid level transmitter 214 is provided on the bottom side wall of the liquid storage chamber; a liquid discharge port 212 is provided at the lowest position of the bottom of the liquid storage chamber, and an automatic liquid discharge valve 213 is provided outside the liquid discharge port 212.

[0032] Working principle:

[0033] The high-speed mixed gas enters the separator from the air inlet of the separator, and the mixed gas makes a spiral motion from top to bottom in the annular compartment ring between the guide ring and the inner wall of the separator. Since the cross-sectional area of ​​the compartment ring is much larger than the diameter of the inlet pipe channel, the flow rate of the mixed gas suddenly drops after entering the separator. The large particles of dust and suspended droplets in the mixed gas settle to the bottom of the reservoir along the inner wall of the separator through cyclone separation under the action of centrifugal force and gravity. The remaining gas and micro dust particles continue to flow along the internal channel of the guide ring to the condensation storage tank behind. The micro dust particles in the gas are filtered and separated again in the stainless steel filter element inside the guide ring. Finally, only a small amount of finer dust and gas flow to the rear condensation storage tank through the connecting pipe between the two devices. When the dust or condensate in the separator reaches a certain height, the level sensor will give a signal to the control system, and the dust or condensate is discharged through the drain valve automatically and manually.

[0034] The condensate collector is arranged at the rear stage of the cyclone separator, and the two are connected by a vacuum pipeline.

[0035] After the mixed gas enters the condensation chamber at the top of the trap, it exchanges heat with the cooling water in the cooling coil. Most of the condensable chemicals in the gas are condensed into liquid. Under the action of gravity, the condensate settles to the bottom of the condensation chamber, and then enters the lower chamber of the condensate trap through the condensate collection pipeline. A liquid level transmitter is installed on the lower side of the condensate trap. When the liquid level in the trap reaches the set height, the PLC vacuum system can automatically close the stop valve on the collection pipeline through the model of the liquid level transmitter, isolate the upper and lower chambers, and break the vacuum of the collection tank at the same time, and then open the automatic drain valve at the bottom of the collection tank. When the liquid level reaches the lowest level, the liquid level transmitter sends a signal to the vacuum system, and the system automatically closes the drain valve and the break valve and automatically opens the stop valve on the condensate collection pipeline.

[0036] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
