Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy recovery and utilization technology, and in particular to an energy conversion and utilization device that uses condensate to drive a turbine to generate electricity. Background Technology
[0002] In chemical production processes, the crude gas shift conversion process generates a large amount of high-pressure condensate, which is ultimately sent to the gasification unit for recycling. However, before being sent to the gasification unit, the condensate needs further treatment to reduce the ammonia and acid gas content, ensuring the long-term stable operation of the gasification unit. In the condensate treatment process, it is often depressurized before being sent to a stripping tower for stripping, reducing the pressure from 3.5 MPa to 0.3 MPa. Therefore, how to effectively recover and utilize the energy in the shift conversion process condensate has become a pressing issue for the shift conversion unit. Utility Model Content
[0003] The purpose of this invention is to address existing problems by providing an energy conversion and utilization device that uses condensate to drive a turbine to generate electricity. This device can convert the energy in the condensate of the conversion process into electrical energy, thereby achieving energy recovery and utilization.
[0004] This utility model is achieved through the following technical solution: an energy conversion and utilization device that uses condensate to drive a turbine to generate electricity, including a buffer tank, a regulating valve installed on the exhaust pipe of the buffer tank, the liquid delivery pipe of the buffer tank being divided into a main liquid pipe and a secondary liquid pipe, a turbine being installed on the secondary liquid pipe, and the main liquid pipe and the secondary liquid pipe converging to connect to a stripping tower.
[0005] As a further improvement to the above solution, the buffer tank is provided with a liquid inlet, through which the pressure of the condensate entering the buffer tank is 3.5 MPa and the temperature is 105°.
[0006] As a further improvement to the above solution, pressure regulating valves are provided on both the main liquid pipe and the auxiliary liquid pipe.
[0007] Controlled by a pressure regulating valve, when the pressure is high, the fuel is sent into the torch for energy conversion and combustion release.
[0008] As a further improvement to the above scheme, the stripping tower is equipped with two discharge ports. One discharge port is connected to the desulfurization tank through a pipeline, and the condensate is reused after desulfurization. The other discharge port is connected to the booster pump, and the pressure is increased by connecting to the gasifier through a pipeline. The condensate is pressurized by the booster pump and then vaporized for reuse.
[0009] Compared with the prior art, this utility model has the following advantages: This utility model uses the condensate from the conversion process to drive the turbine and generate electricity, thereby realizing the recovery and utilization of energy and reducing the energy consumption and production costs of enterprises; by adjusting the turbine inlet regulating valve, the turbine unit can be ensured to operate stably within the set speed range, ensuring stable power generation and transmitting the generated electricity to the power grid; the pressure of the condensate buffer tank is controlled by the pressure regulating valve, and when the pressure is high, it is sent to the flare for energy conversion and combustion. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the process flow of this utility model. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings.
[0012] like Figure 1 As shown, an energy conversion and utilization device that uses condensate to drive a turbine to generate electricity includes a buffer tank. A regulating valve is installed on the exhaust pipe of the buffer tank. The liquid delivery pipe of the buffer tank is divided into a main liquid pipe and a secondary liquid pipe. A turbine is installed on the secondary liquid pipe. The main liquid pipe and the secondary liquid pipe converge and connect to a stripping tower.
[0013] As a further improvement to the above solution, the buffer tank is provided with a liquid inlet, through which the pressure of the condensate entering the buffer tank is 3.5 MPa and the temperature is 105°.
[0014] As a further improvement to the above solution, pressure regulating valves are provided on both the main liquid pipe and the auxiliary liquid pipe.
[0015] The pressure is controlled by a pressure regulating valve. When the pressure is high, the fuel is sent into the torch for energy conversion and combustion.
[0016] As a further improvement to the above scheme, the stripping tower is equipped with two discharge ports. One discharge port is connected to the desulfurization tank through a pipeline, and the condensate is reused after desulfurization. The other discharge port is connected to the booster pump, and the pressure is increased by connecting to the gasifier through a pipeline. The condensate is pressurized by the booster pump and then vaporized for reuse.
[0017] The working principle of an energy conversion and utilization device that uses condensate to drive a turbine for power generation: The high-pressure process condensate (pressure 3.5 MPa, temperature 105°C) generated by the conversion unit (liquid separator, heat exchanger, and ammonia washing tower) is first sent to a newly added condensate buffer tank. The pressure of the high-pressure condensate is controlled by a pressure regulating valve. When the pressure is high, it is sent to the flare. The liquid phase of the condensate is divided into two streams and enters the downstream stripping tower. One main stream enters the stripping tower after passing through a liquid level regulating valve, and the other auxiliary stream is mixed with the main stream by the turbine unit before entering the stripping tower. The turbine unit speed is controlled to operate stably within a set range by adjusting the turbine unit inlet regulating valve. The electricity generated by the turbine unit is sent to the power grid. When the turbine unit needs to be shut down, it is disconnected by closing its inlet and outlet valves.
[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
