Abstract
The invention relates to an industrial exhaust heat gas and an air-powered screw engine which comprises an engine seat, an engine cover, a blank cap, a bearing and a through cover; an inlet is arranged on the engine cover, an outlet is arranged on the engine seat, the engine seat and the engine cover circle to form a cavity by the blank cap and the through cover, a principal axis is arranged in the cavity between the engine seat and the engine cover, one end of the principal axis penetrates through the through cover and is arranged outside an engine seat cavity, one or more than one helical wheels are fixed on the principal axis inside the engine seat cavity, one or more than one helical worm gears can also be fixed on the principal axis, and one or more than one combinations of helical wheels and helical worm gears can also be fixed on the principal axis. The screw engine of the invention uses the steam or hot gas of the industrial exhaust heat to drive the helical wheels and helicalworm gears to push the principal axis to do work; as a single axis structure is adopted, compared with the prior art, the screw engine of the invention has the following advantages of high speed and light load, no exhaust pulsation phenomenon in rotation of the helix, little noise of air flow, little vibration, sound working environment, high volumetric efficiency and long service life.
Description
Technical field
The present invention relates to a kind of industrial exhaust heat steam-operating screw engine.
Background technique
In existing device for generating power by waste heat, adopt twin-screw power engine, i.e. biaxial system mostly.The radial load of double-screw compressor gas is big, so the main frame bearing life of double-screw compressor is shorter, can only work under low exhaust pressure, and the axle bending deflection easily of twin-screw, cause the back lash big, leak also greatlyyer, added clearance volume, so volumetric efficiency is low slightly.It is bigger to impact the gearing noise and the vibration that are produced in addition between the twin-screw flank of tooth mutually.There is engagement pair in its transmission of twin-screw power engine, the requirement on machining accuracy height, and Equipment Requirement height, meshing wear are also inevitable, and the life-span is restricted, and maintenance and operating cost are higher.
Summary of the invention
Purpose of the present invention just provides that a kind of simple in structure, long service life, operation expense are low, the industrial exhaust heat steam-operating screw engine of high working efficiency.
Industrial exhaust heat steam-operating screw engine of the present invention, comprise support, cover, stifle, bearing, Tong Gai, have import on the cover, outlet is located on the support, support and cover surround cavity by stifle, Tong Gai, main shaft is by in the cavity of Bearing Installation between support and cover, one end of main shaft passes logical lid and is located at outside the cavity, be fixed with more than one helical wheel on the main shaft in the cavity, also can be fixed with more than one helical turbine on the main shaft, also can be fixed with the combination of more than one helical wheel and helical turbine on the main shaft.
Industrial exhaust heat steam-operating screw engine of the present invention is to utilize the steam of industrial exhaust heat or hot gas to be power source, and drive helical wheel, helical turbine do work motion of main shaft, because it adopts single-shaft configuration, compared with prior art have the following advantages:
1, high speed light loading, the no exhaust pulsation phenomenon of spiral rotation, pneumatic noise is little, vibrate for a short time, and working environment is better, and does not have the gearing noise that mutual impact is produced between the twin-screw flank of tooth;
2, when work, screw axis can bending deflection, does not have engagement, leaks for a short time, and adding does not have clearance volume, so the volumetric efficiency height;
3, spiral symmetry on the screw axis circumference, gas (vapour) the body radial force that acts on the spiral is cancelled out each other, so the bearing of spiral be not subjected to any axially and the effect of radial force, the bearing life of spiral is prolonged.
