Description
Technical field
The utility model relates to petrochemical machinery fields, and in particular to a kind of second level single screw rod compression for process gas compression
Unit.
Background technique
In petrochemical industry, various gases are often transported, in order to save equipment volume, the gas transported in petrochemical industry is all pressure
Contracting gas, so compressor is indispensable important equipment in petrochemical industry.Currently, it is exactly piston that petrochemical industry is most common
Formula compressor.The gas more demanding for compression degree, frequently with multi-stage compression, still, using the piston type of multi-stage compression
Compressor set, structure is complicated, bulky.
Currently, single screw compressor uses more and more extensive, the compression with other structures in Modern fluid mechanical equipment
Machine is compared, and single screw compressor has structure simple, energy saving, easy to maintain, and it is excellent that single-stage pressure ratio is high, noise and vibration is small etc.
Point.Currently, few people are by single screw compressor in multi-stage compression.
Utility model content
The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and provide a kind of spaces compact,
The second level single screw compressor group for process gas compression saved water.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of second level single screw compressor group for process gas compression, which includes sequentially connected level-one list
Helical-lobe compressor, intercooler, second level single screw compressor and moisture trap, the level-one single screw compressor and two
The shaft of grade single screw compressor passes through two output axis connections of shaft coupling Yu same motor.Wherein, level-one single screw rod
A moisture trap can also be increased after compressor, for guaranteeing that the compressed gas into second level helical-lobe compressor is dry.
The utility model is by two single screw compressors of a motor driven, so that unit space is more compact, cost is cheaper.
The bottom of the moisture trap is connected by pipeline and level-one single screw compressor and second level single screw compressor
It connects, and water cooler is set on pipeline, the water from moisture trap bottom is used for two single screw compressors after cooling
The lubrication and sealing of middle star-wheel and screw rod engagement.Moreover, water of this part for lubrication can cool down to star-wheel and screw rod,
To reduce the temperature of process gas after compression, the series of compressor is reduced.Specifically, the technique of the present apparatus is as follows: process gas
Primary compression is carried out by level-one single screw compressor, the star-wheel and screw rod of level-one single screw compressor are by from moisture trap
Water lubrication and cooling, compressed process gas and water after intercooler cools down, into second level single screw compressor after
Continuous compression, and the star-wheel and screw rod of second level single screw compressor be also by the water lubrication from moisture trap and cooling, finally,
The process gas that compression is completed enters moisture trap together with water, and compressed gas is discharged from the top of moisture trap, and water is then complete
It is recycled at one.
The bottom of the moisture trap is equipped with leakage fluid dram, and top is equipped with filling opening, extra water is discharged by the setting
Or the water of addition loss.
The water cooler and with the connecting line of level-one single screw compressor and second level single screw compressor be equipped with water
Filter.Since the star-wheel and screw rod of single screw compressor are very accurate, so lubricant used must be salt-free water and protect
Card be it is clean, impurity can wear star-wheel and screw rod, shorten the service life of single screw compressor, so on pipeline be arranged filtering
Device guarantees that it is clean for entering the water lubrication agent of two single screw compressors.
The water cooler and with the connecting line of level-one single screw compressor and second level single screw compressor be equipped with stream
Adjustable valve.
The compressor set includes the electricity for controlling motor opening and closing and revolving speed while for controlling flow control valve aperture
Control case.
The intercooler and water cooler is shell-and-tube heat exchanger.
Check valve is equipped between the second level single screw compressor and moisture trap.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) with two output shafts of a motor, two independent compressor hosts is respectively driven, a second level pressure is constituted
The Compressor Group of contracting, so that unit space is more compact, cost is cheaper；
(2) it uses recirculated water as the lubricant of two-stage single screw compressor, realizes lubrication, sealing, and there is cooling effect.
