How Does Co2 Compressor Work？

Bailian Operating principle of carbon dioxide compressor

Carbon dioxide compressor is composed of main engine, motor, base, pipeline system, cooling system and display control system.
The movement mechanism of the carbon dioxide compressor is a crank connecting rod mechanism composed of crankshaft, connecting rod, piston and other parts: the motor drives the crankshaft of the compressor to rotate through the belt, the crankshaft drives the connecting rod, and the connecting rod drives the piston to move in a reciprocating straight line, resulting in changes in the cylinder volume. Since the automatic gas valve determines the suction and exhaust process of the cylinder, the purpose of increasing the gas pressure is achieved. The crankshaft rotates for one cycle to complete a working cycle, and the gas with lower pressure enters the cylinder through the intake port and is compressed into the gas with higher pressure and discharged for use.
There is no liquid lubricant in the carbon dioxide compressor. The piston ring and guide ring are made of high-quality polytetrafluoroethylene with self-lubricating performance. All main parts have certain rust resistance. All bearings are equipped with sealing rings to ensure reliable operation of the machine.

Workflow of Bailian carbon dioxide compressor

Under standard working conditions: carbon dioxide gas is sucked into the first stage cylinder of the compressor through the filter, and then after the first stage compression, it is discharged to the first stage cooler for cooling, and then it is sucked into the second stage cylinder. After the second stage compression, it is discharged to the second stage cooler, and then it is discharged through the check valve (to the high-pressure gas tank - configured by the user) for use. If the suction inlet pressure of the carbon dioxide compressor is ≥ 2.0Mpa, the primary startup valve is closed, and the gas is only compressed by the secondary cylinder of the compressor and discharged to the gas tank. In addition, the set value of the pneumatic valve of the third stage carbon dioxide compressor is: the air inlet value (0.6~1.5Mpa), the first stage pneumatic valve is open, and the other pneumatic valves are closed. Air inlet value (1.5~2.8Mpa) The first and third stage pneumatic valves are closed, and the second stage pneumatic valve is opened. When the inlet air is ＞ 2.8Mpa, the primary and secondary pneumatic valves are closed, and the tertiary pneumatic valves are opened. Unloading solenoid valve is also set on the exhaust pipe to vent the gas in the pipe and cylinder during shutdown to prepare for the next light load startup (to prevent frequent motor startup, restart after shutdown should be more than 3 minutes).
Control mode of carbon dioxide compressor
The carbon dioxide compressor is monitored by pressure sensor, and the startup and shutdown are controlled by two pressure transmitters. The specific control mode is as follows:
Start: when the CO2 inlet pressure exceeds the set value and the starting conditions are met, press the start button to start the main motor.
Stop: when the carbon dioxide inlet pressure is lower than the lower limit (0.5Mpa) and the exhaust pressure reaches the set value, the compressor will stop automatically.

Application of carbon dioxide compressor in beer brewing

Hops are indispensable additives in beer brewing, with unique
Aroma, freshness and bitterness.
Each liter of beer contains about 5 grams of carbon dioxide. When making beer, it is poured into the bottle through a certain pressure. Beer poured into the glass will produce many foam, this foam is called beer hops. Hops are produced in relation to a gas called carbon dioxide. In the brewing process of beer production, carbon dioxide needs to be compressed to dissolve in the liquor, and then bottled and capped. When drinking beer, the pressure inside the bottle is greater than that outside the bottle. As soon as the bottle cap is opened, carbon dioxide will be pumped out one after another, producing many bubbles; Pour the beer into the glass and more bubbles will come out. Beer with substandard carbon dioxide will taste very bad.
Applicable model, CW-600/0.3-5

Carbon dioxide compressor recovery project in dry ice plant

Project background: In the process of making dry ice, dry ice manufacturers will produce a large amount of micro positive pressure CO2 gas due to the volatilization of dry ice, which will not only cause waste of industrial energy, but also fail to meet the requirements of laws and regulations. Therefore, it is necessary to recycle and reuse these CO2 gas.
Applicable model: 3ZW-39/30, micro positive inlet pressure, 30kg exhaust pressure.
