Definitions
- the invention relates to a screw compressor with two parallel screws engaging with each other, one of which is driven while the other is carried, surrounded by a stator housing and provided with an inlet for the gas to be compressed and an outlet for the compressed gas, said stator housing also having at least one inlet through which water is injected into the stator housing, and to a method of operation thereof.
- water only is injected at one point, i.e. near the outlet for the compressed gas.
- the purpose of the water injection is to lower the temperature of the compressed gas and make it as far as possible the same as the inlet temperature of the gas, in particular air.
- a so-called oil-free compressor therefore has great advantages, but no practical embodiments are known in practice.
- the object of the invention is to produce a compressor and a method of operation thereof by means of which it is in fact possible to obtain isothermal compression economically with water injection alone, provided that a number of conditions are met.
- the screw compressor according to the invention is characterized in that said injection point is located at a place in the stator housing where the pressure is equal to 2 3 ⁇ P plus or minus 0.5 bar, and in that further injection points are provided at a place in the stator housing where the pressure is equal to 3 ⁇ P plus or minus 0.5 bar and at the inlet side of the gas, P being equal to the absolute final pressure of the compressor.
- the water therefore has to be injected simultaneously at several, very specific points.
- the method according to the invention is characterized in that the quantity of water injected per unit time is between 1% and 2% of the capacity of the compressor, and the temperature of the injected water is at least 5 K lower than the temperature of the gas at the inlet of the compressor.
- the compressor which is conventional per se, comprises a screw 1 with a driving shaft 2.
- a screw 3 is in engagement with said screw 1 and in operation is carried by the screw 1. There is no mechanical coupling between the two screws or rotors.
- the screws 1 and 3 are supported in and enclosed by a stator housing 4.
- the gas to be compressed is fed in at the lefthand side of the housing 4, through a transverse feed 5 (see Fig. 2).
- the compressed gas is discharged at the righthand side of the housing 4, through an axial outlet 6.
- an injection point is located at point A.
- This injection point A is directed towards the contact face of the rotors 1 and 3.
- point A lies at a place where the pressure is equal to 2 3 ⁇ P plus or minus 0.5 bar, P being equal to the absolute final pressure at the compressor outlet.
- the two points B lie at a place where the pressure is equal to 3 ⁇ P plus or minus 0.5 bar.
- the two points C lie at a place where the pressure is equal to the inlet pressure.
- the injected quantity of water per unit time must lie between 1% and 2% of the capacity of the compressor.
- approximately 50% of the total quantity of water must be injected in point A, approximately 20% in each point B, and approximately 5% in each point C.
- the temperature of the injected water is also of essential importance and must be at least 5 K lower than the temperature of the gas sucked in.
- the example taken is a compressor with an absolute pressure of 7 bar and a speed of 6,475 rpm.
- the shaft power is 7.38 kW/m3/min.
- the shaft power is 6.03 kW/m3/min.
