Abstract
The utility model relates to a vapour-water heat exchanger which is particularly suitable to the places with steam boilers simultaneously supplying two heating medium of vapour and hot water, which is composed of a vapour-water mixer, a water supply valve, a steam inlet valve and a booster pump. The entrance of the booster pump is communicated with a connection tube of a mixing chamber of the vapour-water mixer, and the exit of the booster pump is connected with the water supply valve. The utility model can realize the stable operation of a system with shockproofness and low noise when connected and operated in the system.
Description
A kind of vapour-hydrothermal exchange device is particularly suitable for the place that steam boiler is supplied steam and two kinds of heating agents of hot water simultaneously.
With the user of steam, when needing simultaneously heat with a part of steam to change into hot water to be used for heating, two kinds of solutions are arranged in the prior art: 1, realize vapour-hydrothermal exchange, 2, realize above-mentioned conversion with steam jet ejector with heat exchanger as thermal source.Realize that with heat exchanger the equipment of vapour-hydrothermal exchange is pressure vessel and equipment, complex structure, floor space is big, and the maintenance requirement height involves great expense; Though realize that with steam jet ejector vapour-hydrothermal exchange can address the above problem, but, produce vibration and noise when changing in working order, when particularly starting and stopping because the scope of steam jet ejector adaptation vapour source pressure oscillation is too little, vibrate more strongly, so that influence system's operate as normal.
The purpose of this utility model, provide a kind of vapour-hydrothermal exchange device, its structure is simpler than heat exchanger, use processing ease, floor space is little, and cost is low, and its performance is compared adaptation vapour source pressure oscillation scope with steam jet ejector big, can realize friction, low noise, thereby make the work of system stability ground.
Vapour described in the utility model-hydrothermal exchange device, comprise steam heater (1), water supply valve (4), backwater valve (5), steam inlet valve (9), steam inlet valve (9) is connected on the steam connection (16) of steam heater (1), backwater valve (5) is connected on the return pipe (18) of steam heater (1), it is characterized in that, have one to start bleeder pipe (15) and drain pipe (17) on the steam connection (16) of steam heater (1), have one to start bleeder pipe (13) on the flume (12).
Mixing chamber (10) is connected in the adapter (2) by reducer pipe (11), and the other end of taking over (2) is connected the inlet of booster (3), and the outlet of booster (3) connects water supply valve (4).Startup bleeder pipe (13), (15) connect respectively and start venting valve (6), (8), and drain pipe (17) connects hydrophobic valve (7).Take over (2) be length greater than 2 mitron, its axis is straight line or curve.
During use, steam inlet valve (9) is connected vapour source, water supply valve (4) is connected hot user's feed pipe, backwater valve (5) is connected hot user's return pipe, constituted heating system.Steam is in steam inlet valve (9) enters blender (1), by steam jet (14) ejection at a high speed, the flume (12) of injection backwater in backwater valve (5) enters blender (1), backwater and steam enter mixing chamber (10) together and take over (2) and carry out mixed heat transfer mutually and become hot water and enter booster (3), and the pressurization back is sent to the heating user with certain pressure from water supply valve (4).Reduce through the heat hydraulic pressure behind the radiator heat-dissipation, arrive backwater valve (5), enter the blender heat exchange by steam ejection once more, send into system, realize circulation by the booster pressurization.
Realize the conveying of boosting of hot water owing to adopt booster in the utility model, make the flow and the resistance of heating system basicly stable, reduced the influence of vapour source pressure oscillation to system, owing to adopted drain pipe and drain valve to sluice, friction in the entire work process, low noise have been realized simultaneously.
The utility model is compared with heat exchanger, and is simple in structure, processing ease, and floor space is little, and cost is low.Compare with steam jet ejector, the scope that adapts to vapour source pressure oscillation is big, can realize friction, low noise, thereby keeps the work of system stability ground.
