Abstract
The invention relates to a steam jet type heater. The steam jet type heater mainly comprises a steam jet pipe, a shell, a piston, a cold medium inlet, an end cover, a hot medium inlet, a sealing ring, a baffle ring, a spiral wing, a spring and a mixed medium outlet. The steam jet type heater has the characteristics that energy is saved, a steam hammer is not used, media are fully mixed in the heater, heating is instantly performed, and the structure is compact.
Description
Technical field
Steam-sprayed heater of the present invention belongs to a kind of in the contact heat exchanger, is mainly used in the techniques such as food, chemical industry, pharmacy, pulping and paper-making.
Background technology
Existing contact heat transmission equipment, two kinds of heat transferring mediums can not fully contact, and the heat that thermal medium is come out can not be absorbed fully by cold medium, and heat utilization rate is lower, and firing rate is slow, and the occupation of land space is larger, and manufacturing cost is higher.
Summary of the invention
Purpose of the present invention for overcoming defects, provides a kind of conserve energy, without steam hammer, mixes transient heating, the contact heat transmission equipment of compact conformation in the heater fully.
The present invention can fully contact with liquid to be heated steam, and rapidly, continuously, directly heats any water soluble fluid or slurries.Heater directly injects the steam in the liquid by the aperture on the playpipe, and small steam " bubble " is rapidly by liquid absorption, thereby realizes 100% thermal energy exchange.Increase when the steam demand amount has, when subtracting, the band spring piston of a uniqueness just rises or descends.So just prevented vapour pressure near fluid pressure, thereby eliminated steam hammer, the spiral fin in cavity can promote steam to mix fully with fluid.
For achieving the above object, adopt following structure: a kind of steam-sprayed heater is mainly by steam-jet siphon, housing, piston, cold medium import, end cap, the thermal medium import, sealing ring, back-up ring, helical wing plate, spring, the blending agent outlet forms, be covered with hole on the described steam-jet siphon, be provided with piston in the steam-jet siphon, one in piston links to each other with spring, one links to each other with back-up ring, steam-jet siphon links to each other with the thermal medium import, there is the housing with helical wing plate the steam-jet siphon outside, leave the gap between steam-jet siphon and housing, also be provided with the outlet of cold medium import and blending agent on the housing, housing thermal medium entrance point is provided with end cap, between be provided with sealing ring, make housing seal.
The core of steam-sprayed heater is steam-jet siphon, with the piston of spring and with the housing of helical wing plate.Steam-jet siphon makes this heater play following effect with piston with spring: 1.. and playpipe scatters into tiny vapor stream with steam.2.. piston is regulated automatically according to the variation of steam demand amount, to keep the pressure differential between steam and the liquid.3.. piston also autoshutdown when shutting down, crumble and fall suddenly with the steam that prevents steam pipe.
Helical wing plate and housing can guarantee like this that generally by the hot investment casting moulding housing and helical wing plate become an integral body, guarantee both intensity.Cold medium entrance sleeve and blending agent discharge connection all weld with housing.Vessel flange and housing are by being welded to connect.Thermal medium (steam) entrance sleeve and playpipe are threaded connection, and thermal medium entrance sleeve and end cap are by being welded to connect.Housing is connected (heater the latter half) in aggregates with vessel flange, cold medium entrance sleeve with flange, blending agent discharge connection with flange, helical wing plate like this.Thermal medium (steam) entrance sleeve and flange, playpipe and end cap connect into as a whole (heater the first half).Heater the first half is connected studs, nut, sealing ring and is connected in aggregates with the latter half.Can see that by above structure the connection of each parts of from heater core had both guaranteed the intensity of heater, allowed again heater have dismoutability, convenient for maintaining and cleaning.Helical wing plate can allow steam fully contact with liquid to be heated, guarantees the heating effect of heater.
The invention has the beneficial effects as follows: conserve energy: steam-sprayed heater belongs to a kind of in the contact heat transmission equipment, compare with shell-and-tube or the plate type heat exchanger of contactless heat exchange, this heater can make two media that participate in heat exchange fully contact, guarantee that the energy of vapor evolution is all by liquid absorption, improve the heat utilization rate of heater, can reduce the fuel consumption up to 28%.
Without steam hammer: unique playpipe can keep the minimum differntial pressure between steam and the liquid automatically, to eliminate harmful vibrations and steam hammer.
Mix fully in the heater: need not the heater back and add again a straight length, finished the abundant mixing of medium in heater inside.
Transient heating: steam-sprayed heater can provide unlimited hydrothermal solution to supply with as required continuously, need not large-scale storage tank.
Compact conformation: compare with traditional heat exchangers, steam-sprayed heater only needs very little space, occupation of land space and the manufacturing cost of reduction equipment.
