The invention discloses an environment-friendly multi-channel water jet air extractor, which comprises two working nozzles, the two working nozzles are installed at one end inside the studio, the tails of the two working nozzles are directly facing the working medium inlet connected to the working room, and the water medium Enter the working nozzle from the inlet of the working medium, and the other end of the working chamber is connected to one end of the two throats. The nozzles of the two working nozzles are respectively facing the inlets of the two throats. The nozzles of the working nozzle spray the medium into the throat. The outer surface of the studio is connected to the air inlet, and the gas enters the interior of the studio from the air inlet. A one-way valve is installed at the mouth of the air inlet to ensure that the gas enters the interior of the studio from the air inlet in one direction, and the throat is placed in the noise-proof cover Inside, the other end of the throat is connected to the outlet chamber of the throat, and the surface of the outlet chamber of the throat is provided with a residual speed suction port. The invention has the advantages of low consumption, high efficiency and low noise.
Description
technical field [0001] The invention belongs to the technical field of power generation equipment, and relates to an environment-friendly multi-channel jet water extractor. Background technique [0002] The new high-efficiency and environment-friendly multi-channel jet water extractor is a kind of equipment for the steam turbine unit of the thermal power plant to suck the vacuum of the condenser and other equipment that needs to be vacuumed. The vacuuming equipment for the condenser mainly includes vacuum pumps and air extractors. There are two types of air extractors: water jet and air jet. At present, the water jet air extractor is widely used in domestic large and medium-sized units because of its simple system and reliable operation. [0003] During the start-up process of the unit, when the boiler ignites and the steam turbine enters the steam heater, more steam will enter the condenser. If a certain vacuum is not established in the condenser, the steam entering the con...
