Abstract
The utility model provides a one-half stage flue gas turbine, which comprising a base, a bearing box body and an exhaust shell which are arranged on the base; a probe provided on the bearing box body; a rotor composed of a main shaft mounted on the front and back bearing components in the bearing box body, a wheel disc fixed on the main shaft and a plurality of vanes fixed on the wheel disc; an intake cone fixed on the exhaust shell; an inlet flange mounted on the intake cone; an outlet flange mounted on the exhaust shell; and a first stage diversion component and a second diversion component which are respectively fixed on the intake cone and the exhaust shell. The utility model has simplified structure, high reliability and reduced cost, can effectively recycle the heat energy and pressure energy of flue gas of 85%, and is mainly used to recycle the heat and pressure energy of flue gas.
Description
Technical field
This reality and novelly relate to a kind of energy recycle device particularly relates to a kind of one-level half flue gas turbine expander device.
Background technique
At present, flue gas turbine expander mostly is single-stage and twin-stage, and bipolar advantage is the reuse efficiency height, can reach 88%, and shortcoming is a complex structure, and number of spare parts is many, and the design and manufacture cost height is particularly owing to increased rotational parts, reliability decrease.And the advantage of single-stage is simple in structure, and design and manufacture cost is low, the reliability height, but reuse efficiency is undesirable, particularly under high blow down ratio situation, about 70%, existing flue gas turbine expander work blow down ratio is about 3, so single step arrangement can not effectively reclaim the flue gas pressures energy.
Summary of the invention
The purpose of this utility model is the advantage of comprehensive single-stage and two-stage flue gas expander, and a kind of designs simplification is provided, the reliability height, and cost reduces, and can effectively reclaim the one-level half flue gas turbine expander device of flue gas heat and pressure energy.
The utility model one-level half flue gas turbine expander device comprises base, be arranged on bearing housing and exhaust casing on the base, be arranged on the probe on the bearing housing, before being installed in the bearing housing, main shaft on the rear bearing assembly, be fixed on a wheel disc on the main shaft and be fixed on the rotor that one group of moving vane on the wheel disc constitutes, be installed in the air inlet cone on the exhaust casing, be installed in the suction flange on the air inlet cone, be installed in the outlet(discharge) flange on the exhaust casing, by be fixed on the one-level water conservancy diversion ring body on the air inlet cone and be fixed on the one-level water conservancy diversion ring body and be positioned at moving vane before the one-level guiding subassembly that constitutes of one-level guide vane, and by be fixed on the exhaust casing and the secondary water conservancy diversion ring body that is connected with the air inlet cone and be fixed on the secondary water conservancy diversion ring body and be positioned at moving vane after the secondary guiding subassembly that constitutes of secondary guide vane.
The working principle of the utility model one-level half flue gas turbine expander device is, flue gas enters the air inlet cone by pipeline under the control of valve, after the district's expansion of one-level guide vane, step-down, acceleration, enter the moving vane district, carry out the expansion second time, step-down again in secondary guide vane district, and to reaction thrust of moving vane, thereby reduce vibration, balancing rotor.In one-level guide vane, movable vane section and secondary guide vane district, the heat energy of flue gas and pressure can partly change the mechanical energy that drives rotor rotation into, and another part then enters exhaust heat boiler from exhaust casing.
The advantage of the utility model one-level half flue gas turbine expander device is the advantage of comprehensive single-stage and two-stage flue gas expander, designs simplification, and the reliability height, cost reduces, and can effectively reclaim flue gas heat and pressure energy, and the recovery rate reaches 85%.Be mainly used in and reclaim flue gas heat and pressure energy.
