Description
Technical field
Equipment is generated the present invention relates to a kind of steam and the method for generating steam.
Background technology
In many steaming plants, water is delivered to hot surface by the especially big equipment of those steam flows using electric pump
To evaporate as needed.In some equipment, usually in user's activation trigger device, made using the water of electric pump self-measuring in future head
It is delivered on evaporating surface for single stream or jet stream.
In some applications, water needs to spread in larger area, preferably to extract heat, and obtains in turn more
Good volatility.In such application, spray nozzle or jet blower (or more jet blowers) can be used water-dispersed larger
On evaporating surface.
Due to the use of water may contain and result in the salt and compound of incrustation scale, so should avoid water using spray nozzle
It is spread across on evaporating surface, because small nozzle opening is easy to be blocked by incrustation scale, fails so as to cause vaporization function.
Nozzle with larger open is more resistant against incrustation scale blockage problem.However, water may be along steam surface along very
Narrow path flowing, and therefore high velocity vapor generation will need the evaporating surface grown very much to ensure water by steam generator
Evaporating completely, it is huge so as to cause device volume.In addition, the jet stream impinged upon on evaporating surface causes to fall in steam generator
Water droplet sputtering on other components, to reduce evaporation efficiency, (fall be not on direct-fired component to evaporative effect after extension
Water take longer for evaporating).
Invention content
It is an object of the present invention to provide it is a kind of can to avoid or alleviate the above problem for generating setting for steam
It is standby.
The present invention is defined in the independent claim.Dependent claims limit preferred embodiment.
According to the present invention, a kind of equipment for generating steam is provided.
The present invention relates to a kind of equipment for generating steam.The equipment includes：Evaporation element comprising water evaporation table

Make water from the surface that the baffle flow to the evaporation element, and the wherein described evaporation element is configured to make water in evaporation member
It is flowed downward on part to be evaporated.
The baffle helps to be distributed water on the larger width (or area) of baffle, and it is whole that water is delivered to evaporation element
Evaporating surface on a width (or area).Since water is distributed on larger width or area, water evaporation surface can keep compared with
Short (along water flowing direction on evaporating surface), to obtain greater compactness of equipment.

It collects.The container could be provided as close to the plate-like piece.
Compared with plate-like piece is horizontal situation, distribute the water on the inclined plate-like piece or evaporation element heated,
Film can be formed it into and faster evaporated.Since the film for the water being fed on plate-like piece or evaporation element is relative to the table heated
It is cold for face, so any incrustation scale on plate-like piece or evaporation element all will be by thermal shock.That is, the cooling of water
In the arbitrary incrustation scale that the heating effect on effect (at least before its evaporation) and surface will be formed on the surface induce thermal stress and
Tension, and cause it broken and removed from surface.
The angle of inclination on plate-like piece surface leads to lower end of the removed incrustation scale along the surface of plate-like piece downwardly toward plate-like piece
It is mobile, and eventually enter into container.In addition, the angle of inclination of plate-like piece helps to improve evaporation efficiency.Plate-like piece surface it is steep
