Detailed Description
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:
referring to fig. 1 to 5, the present invention is a gas-liquid two-phase ejector for purifying harmful gas, including: main flow pipeline 1, mixing pipeline 2, hollow vane swirler 3.
The main flow pipe 1 is connected with a mixing pipe 2. Be equipped with four circumference evenly distributed's atomizing treatment liquid entry 2.3 on the hybrid tube outer shell 2.1, hybrid tube inner shell 2.2 and hybrid tube outer shell 2.1 welded connection are equipped with internal clearance 2.5 in order to transport atomizing treatment liquid between, are equipped with atomizing treatment liquid entry 2.4 on the hybrid tube inner shell 2.2. The hollow vane swirler 3 is in one-to-one correspondence with the atomized treatment liquid inlets 2.4 through hollow vanes 3.2 and is connected in a welding manner, and the tail part of the hollow vane swirler 3 is provided with an atomized treatment liquid injection port 3.1. The atomized treatment liquid firstly enters a gap 2.5 between the outer shell and the inner shell through an inlet 2.3 on the outer shell, enters a vane swirler pipeline through an inlet arranged at the throat part of the inner shell, and finally is sprayed out from a jet orifice at the tail part of the swirler to be mixed with harmful gas for removal.
The gas-liquid two-phase ejector is divided into a main flow pipeline 1 and a mixing pipeline 2, the main flow pipeline 1 can be integrated with the kitchen waste sealing box, and the mixing pipeline 2 can be integrated with the harmful gas treatment liquid atomization device; the injection area can be changed through changing the position of the lower section of the pipeline according to actual requirements during working, and then the air content is mixed.
The number of the atomized treatment liquid inlets arranged on the mixing pipeline shell is four, and the atomized treatment liquid inlets are uniformly distributed along the circumferential direction.
The spraying position at the tail part of the hollow vane swirler is conical, so that the atomized treatment liquid is sprayed and uniformly mixed.
The inner shell and the outer shell of the mixing pipeline are connected in a welding mode to form an internal sealed space for conveying atomized treatment liquid.
