[specific embodiment]
Can explain in more detail the present invention by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Low pressure steam recovering device described in 1 by reference to the accompanying drawings, the housing 1 that described device comprises straight-tube shape, and be arranged on successively funnelform nozzle 4, steam-water mixing chamber 6 and the pumping chamber 7 of housing 1 inside; Described housing 1 one end is made as the water inlet 2 for inputting water liquid, the other end of housing 1 is made as the steam water interface outlet 3 for exporting, simultaneously, be fixed with one in the interior stage casing of housing 1 and divide device 5 for the air ring that the low-pressure steam sucking is shunted, and be just arranged on the corresponding air ring of housing 1 and divide the side shell wall between device 5 and the conical cavity of nozzle 4 for sucking the air intake 8 of low-pressure steam, this air intake 8 at right angles cross-like corresponding to housing 1, and the sidewall stage casing of air intake 8 is provided with an admission place pressure vacuum mouth 9; The device pressure vacuum mouth 10 that the shell wall of housing 1 correspondence between steam-water mixing chamber 6 osculum ends and pumping chamber's 7 osculum ends is provided with a pressurization of the mixture for the water in housing 1 and vapour and detects;
The described corresponding water inlet 2 of nozzle 4 big opening ends, the osculum end of nozzle 4 runs through air ring and divides the rear correspondence of device 5 to be positioned at the conical cavity of steam-water mixing chamber 6, be that water liquid is entered by the big opening end of nozzle 4, be then ejected in the conical cavity of steam-water mixing chamber 6 at a high speed by the osculum end of nozzle 4; Now, the flow at high speed of water is at the interior formation air-flow of housing 1, and make this section of cavity between nozzle 4 outer walls and housing 1 form vacuum, be that admission place pressure vacuum mouth 9 is in vacuum state, thereby can be by air intake 8 by low-pressure steam suction casing 1, and the low-pressure steam that makes to suck carries out mixed heat transfer with the water spraying into divide the shunting of device 5 by air ring along housing 1 inside after in the conical cavity of steam-water mixing chamber 6;
The big opening end of described steam-water mixing chamber 6 divides device 5 corresponding with air ring, thereby is beneficial to full and uniform the entering in steam-water mixing chamber 6 of low-pressure steam of suction; The osculum end of steam-water mixing chamber 6 is corresponding with the osculum end of pumping chamber 7, thereby is convenient to enter in pumping chamber 7 at a high speed at water, the vapour of the 6 interior mixing of steam-water mixing chamber; The big opening end of pumping chamber 7 overlaps with the steam water interface outlet 3 of housing 1, and the steam water interface that utilizes the conical cavity of pumping chamber 7 to make to enter in pumping chamber 7 reduces flow velocity, and reaches the object being output under elevated pressures; For ease of regulating nozzle 4 to spray the flow velocity of water according to the concrete condition of low-pressure steam, so that water reaches relative best admixture with vapour, described nozzle 4 is provided with an adjustable pitch device that can move axially and locate along housing 1, thereby reaches the object of being convenient to adjust spacing between nozzle 4 and steam-water mixing chamber 6.
While implementing low pressure steam recovering device described in the utility model, only described housing 1 need be fastened in corresponding pipeline, more can use after air intake 8 is connected with the pipeline of corresponding discharge low-pressure steam; Water enters housing 1 by water inlet 2
afterspray with high flow rate through nozzle 4, make admission place pressure vacuum mouth 9 in vacuum state, thereby by air intake 8, low-pressure steam is sucked, the low-pressure steam sucking is mixed to form two-phase fluid field with the water spraying into after air ring divides device 5 shuntings in steam-water mixing chamber 6, and vapour and water start fully to exchange; According to two phase flow characteristic, in gas-vapor mix, the velocity of sound only has 10 meter per seconds, and steam water interface stream scooter 40 meter per seconds, therefore, steam water interface can form Supersonic Flow; When steam water interface forms Supersonic Flow, and while flowing with high-speed smooth in the straight length of steam-water mixing chamber 6, vapour fully mixes with water, thereby 10 places form vacuum at device pressure vacuum mouth, and then steam water interface can be changed by the subsonic flow of supersonic flow trend in the time entering the straight length of pumping chamber 7, and while mineralization pressure shock wave, finally utilize described device to reach the object with elevated pressures output with uniform temperature hot water.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
