Task of the present utility model is to provide a kind of reaching simultaneously to eliminate the noise and energy-conservation, durable direct-type steam heater.

The utility model is in the following way to realize above-mentioned task: utilize spraying technique to make steam and water mixed, and reach noise elimination in the heating process and energy-conservation.Structure of the present utility model comprises a long circular cylinder body, is communicated with the steam connection of this barrel front end and the aft bulkhead that this cylinder back-end of sealing has many little taps.Characteristics of the present utility model are: a preceding dividing plate and a rear bulkhead are arranged in above-mentioned cylindrical shell, cylinder lumen is separated into ante-chamber, lumen and three separate cavities of back cavity, ante-chamber is an air chamber, connect with steam pipe, lumen is an intake chamber, logical with peripheral ditch by the many perforation that had on its barrel, back cavity is a mixing chamber, realizes that vapour, water mix; Before dividing plate and rear bulkhead distribute evenly that many numbers equate and the position respectively front to back registration be in the perforation of same axis, a convergent-divergent shape spout that extends back is housed in each hole of preceding dividing plate, a sleeve pipe that extends back is housed in each hole of rear bulkhead, the convergent-divergent shape spout of front is just in time aimed at the sleeve of back, and their axis is parallel with the axis of above-mentioned cylindrical shell.Operation principle of the present utility model is: enter cylindrical shell ante-chamber air chamber as the steam of thermal source by the steam connection of barrel front end, vapor stream sprays into after being accelerated through convergent-divergent shape spout in thereafter the sleeve pipe; By jet-action, the water that the perforation from cylindrical shell lumen barrel enters intake chamber is inhaled by steam jet and is entered the sleeve pipe simultaneously; This sleeve pipe is mixed cover, and steam and water moves in mixed cover and carries out the exchange of momentum and heat energy on one side, overlaps the exit mixing, and steam has been condensed into water, becomes one hot water from the ejection of portalling of the float of cylinder back-end wall; Because the utility model places water tank, heated water is inhaled into by the perforation of intake chamber barrel continuously, then carry out heat exchange with steam and turn back in the water tank, thereby the water in the water tank constantly is heated.

The utility model has the advantages that conspicuous owing to from the water that this heater outlet flows out, do not had steam bubble, so can eliminate steam bubble row to the heat of atmosphere and an energy-conserving action; Because the speed difference of water and steam makes steam bubble be split into superfine little steam bubble by water cutting when condensing in mixed cover water, thereby reduce the impact noise that sent when the steam bubble entry is condensed greatly, play the noise elimination effect; Owing to do not adopt flimsy copper wire cloth, structure is firm simultaneously, long service life, and also cost is low.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
