Description

A kind of release device of steam in a liquid

Technical field

The utility model relates to a kind of release device of steam in a liquid.

Background technique

In industry with civil heat supply system, steam is widely used as a kind of heat source.Liquid is directly inputted with steam Body heats liquid, and the method widely used.But the shortcomings that steam heating also has its own, that is, carrying out Biggish vibration and noise can be generated when heat exchange, when this is primarily due to steam and is discharged from pipeline, due to large-minded, stream It is fast fast, it cannot dissolve in water immediately, will form steam bubble that is biggish, being wrapped in by water, steam bubble quilt under the action of cold water Condensation, volume are reduced rapidly rapidly, and original interface disappears, to generate sharp impacts, form biggish vibration and noise, In order to solve this problem, Chinese patent CN200620032486 was once disclosed a kind of " jet flow composite type steam and hot water muffler ", Its main feature is that accelerating to be sprayed into hush tube by steam nozzle in steam, high velocity vapor jet stream injection sucks cold water, and pushes noise elimination Water in pipe travels forward, and the contraction that steam condensation generates in taper hush tube is limited by tube wall, to eliminate vibration and make an uproar Sound.Although this device can eliminate a part of noise, whole erasure effect is not ideal enough, and the temperature for heating water is also limited Under normal pressure 68 DEG C, while applicable steam pressure range is also relatively narrow, volume is larger.The content of the present invention is for existing Deficiency existing for technology has carried out more scientific in such a way that pulse scatter macro and micropore jet jet stream combine Design, the purpose of this utility model is to provide a kind of noise elimination effects, and steam pressure range that is more preferable, using is wider, under normal pressure The temperature that can heat liquid is higher, small in size, light-weight, heating is fast and novel steam easy for installation is released liquid is intracorporal Put device.

Utility model content

The release device of a kind of steam in a liquid that in order to achieve the above purposes, the technical solution adopted by the utility model is:, It is connected by steam inlet 1 with jet chimney outlet, steam enters pulse generation chamber 2 by steam inlet 1, by machinery Impact generates pulse, and enters spray-hole 4 by flow increasing nest 3 and spray, and enters mixing lumen 6 by injection annular space 5, passes through simultaneously Cold water is introduced by annular space 5 and is mixing mixed heat transfer in lumen 6 with steam, sprays hot water from the outlet of mixing lumen 6.

The utility model is by above technical scheme, the advantage is that: the volume of muffler is reduced by design above, Steam flow is increased, the velocity ratio and mass ratio of steam and water are more reasonable, are crushed steam bubble by pulse oscillating and are allowed to micro- Change, so that the contact area of steam and water be made to increase 1~3 order of magnitude, and has been mixed rapidly in limited small space At heat exchange.Obtain lower noise, preferably eliminate in low-frequency vibration, can under normal pressure water temperature heating to 100 DEG C, And improve the technical indicators such as applicable steam pressure range, heat exchange efficiency, steam utilization.Meanwhile improving the benefit of material With rate, raw material are saved.

Detailed description of the invention:

Appended drawing reference:

1. 4. spray-hole of steam inlet 2. pulse generation chamber, 3. flow increasing nest, 5. injection annular space 6. mixes lumen

Specific embodiment

Be machined on pitch circle column type metal (or alloy) bar, formed steam inlet 1, pulse generation chamber 2, Injection annular space 5 etc., then drilling forms several mixing lumens 6 and spray-hole 4 on one end of pole, later with dedicated It draws one end of rotary cutter processing spray-hole 4 to form flow increasing nest 3, both completes manufacturing process.

The device can be by the machining internal thread at steam inlet 1 or welding metal pipe after being made, and is adding outside Metal tube on the modes such as threading or welded flange, link together with jet chimney, be placed on and need to heat In liquid, without friction, low noise, efficient heating can be realized.
