Description

Technical Field

[0001] The invention relates to the technical field of power generation equipment, and in particular to a turbine generator operated by utilizing condensation negative pressure. Background Art

[0002] Traditional turbine engines usually rely on high-temperature and high-pressure gas generated by fuel combustion to drive the turbine to rotate to generate electricity. This method has problems such as limited energy utilization efficiency and great impact on the environment. With the growth of energy demand and the improvement of environmental protection requirements, it is necessary to develop more efficient and environmentally friendly power generation technologies. At present, there is no mature technical solution to fully utilize the negative pressure generated by the condensed water after thermoelectric power generation to achieve secondary power generation. Summary of the invention

[0003] 1. Purpose of the invention: The purpose of the present invention is to provide a turbine generator that operates using condensing negative pressure to improve energy utilization efficiency, achieve secondary utilization of energy, and reduce power generation costs and impact on the environment.

[0004] 2. Technical solution

[0005] The turbine generator of the present invention mainly includes the following components:

[0006] Exhaust hole (001): Located at a specific position of the motor, it is the exhaust channel for the air flow, used to discharge the gas after the turbine has done work, maintaining the air pressure balance and air flow circulation in the system.

[0007] Flow hole (002): A box can be added at this position for injecting liquid coolant. By injecting liquid coolant, the temperature of the outflowing gas is reduced, and the gas pressure is further reduced, thereby increasing the negative pressure and improving the efficiency of the turbine generator.

[0008] Connecting shaft (003): plays a connecting role, transferring the rotational motion of the turbine to the generator part to ensure the effective transmission of power. The connecting shaft is made of special materials and processes, with high strength, high precision and good wear resistance.

[0009] Emergency pressure relief hole (004): equipped with a valve, when the air pressure is extremely unstable, the valve will automatically open to release the excessive air pressure and protect the equipment from damage. The opening pressure of the valve is precisely set, the response speed is fast, and the sealing performance is good.

[0010] Air inlet (005): It is the entrance for negative pressure airflow to enter the turbine generator. Its design shape, size and air intake direction are optimized to ensure that the airflow enters the turbine evenly and stably, thereby improving the working efficiency of the turbine.

[0011] Main electric valve (006): It is not only the channel for the DC power generated by the motor to be exported, but also the main on / off valve of the motor. The main electric valve has parameters such as rated current and withstand voltage level that meet the design requirements. It is also equipped with overcurrent protection, short-circuit protection and other devices to ensure safe and stable DC power export and reliable control of the start and stop of the motor.

[0012] Working principle: During the thermoelectric power generation process, the condensed water produced has a low temperature and low air pressure, forming a negative pressure. Under the action of negative pressure, the outside air enters the turbine generator from the air inlet, driving the turbine to rotate. The turbine drives the generator to generate electricity through the connecting shaft. The gas after the turbine has done work is discharged from the discharge hole. In this process, by injecting liquid coolant at the flow hole, the air pressure of the outflowing gas can be further reduced, the negative pressure can be increased, and the speed and power generation efficiency of the turbine can be improved. When the air pressure in the system is extremely unstable, the valve of the emergency pressure relief hole automatically opens to release the excessive air pressure and protect the safety of the equipment.

[0013] 3. Beneficial effects

[0014] High energy efficiency: By utilizing the condensation negative pressure to achieve secondary power generation, energy can be fully utilized. Compared with traditional turbine engines, the power generation efficiency can be increased by [X]% under the same energy input. Environmental protection and energy saving: It reduces dependence on traditional fuels, reduces exhaust emissions, and meets environmental protection requirements. At the same time, it realizes the secondary utilization of energy and saves energy resources. Good stability: The design of components such as emergency pressure relief holes and main electric valves improves the stability and reliability of the equipment and reduces the probability of equipment failure.

The connecting shaft is made of high-quality alloy steel and undergoes a special heat treatment process to improve its strength and wear resistance.

[0016] 2. Manufacturing process: The turbine is manufactured using precision casting technology to ensure the shape and size accuracy of the turbine blades. The connecting shaft is processed using high-precision lathes and grinders to ensure its concentricity and surface roughness. The box is manufactured using welding technology to ensure its sealing and strength.
