Condensation ejector

Abstract

The invention discloses a condensation ejector which comprises an accepting chamber, a throat chamber, a mixing chamber, a dispersion chamber, a condensing chamber and an atomizing mechanism, wherein the accepting chamber is provided with a first inlet and a second inlet; one end of the throat chamber is communicated with the accepting chamber, and the throat chamber is located on the down stream of the second inlet; one end of the mixing chamber is communicated with the other end of the throat chamber, one end of the dispersion chamber is communicated with the other end of the mixing chamber, and a first outlet is formed in the other end of the dispersion chamber; the condensing chamber is arranged close to the outer side of the down stream of the mixing chamber in a surrounding mode and comprises a third inlet formed in the down stream end of the condensing chamber, a second outlet formed in the upstream of the condensing chamber, a plurality of main condensing pipes and a plurality of branch condensing pipes, one end of each of the condensing pipes extends into the mixing chamber, the extending directions of the branch condensing pipes are different, the other end of each of the branch condensing pipes is communicated with a main condensing pipe, one end of the main condensing pipe is sealed, and the other end of the main condensing pipe is communicated with the dispersion chamber through a fourth inlet in the dispersion chamber; the atomizing mechanism is provided with a plurality of nozzles formed in the position of the fourth inlet, and the atomizing mechanism is used for atomizing fluid in the main condensing pipe and spraying the fluid in the dispersion chamber.

Description

technical field [0001] The present invention relates to a condensation ejector. Background technique [0002] Waste heat power generation refers to the technology of converting excess heat energy in the production process into electrical energy. The waste heat and pressure utilization project is one of the ten key energy-saving projects in my country's "Special Plan for Energy Conservation Mid- and Long-term Development". It uses the heat or combustible substances in waste gas, waste liquid and other working fluids as a heat source to produce steam for power generation. The waste heat used for power generation mainly includes high-temperature flue gas waste heat, chemical reaction waste heat, waste gas, waste liquid waste heat, and low-temperature waste heat below 200°C. Organic Rankine Cycle (Organic Rankine Cycle) referred to as ORC, is a Rankine power cycle that uses organic matter instead of water as the working medium to recover low-grade heat energy. Using the organ...
