Abstract

The utility model relates to a novel vacuum phase-change energy-saving safe hot water boiler. A heat exchanger of a steel shell-and-pipe spiral grooved pipe is respectively added in a present upper boiler cylinder and a present coal economizer. Circulating water passes through the upper cylinder and the coal economizer twice to be heated. Heat medium water is boiled and operated under the state of seal, low temperature (96-99 DEG C) and negative pressure (0-0.012 MPa). A water pipe for thermoregulation is arranged in the water space of the upper boiler cylinder, which can finely adjust the temperature of the heat medium water and can also boil water.

Description

Novel vacuum phase transition energy-saving safety hot-water boiler is the improved design that belongs to phase transition of vacuum energy-saving safety hot-water boiler.At present, known phase transition of vacuum energy-saving safety hot-water boiler is to be made of upper drum and economizer two parts.At their upper space, a copper spiral coil heat exchange device has been installed respectively, " heat medium water " be low temperature, the boiling of little negative pressure, operation under air-tight state, and phase-change heat-exchange can reach efficient, energy-conservation, purpose of safety.But this boiler structure complexity is made, installs, is repaired difficulty, and material is expensive, cost is high, function singleness.
The purpose of this utility model provides a kind of novel vacuum phase transition energy-saving safety hot-water boiler, and this boiler can not only be efficient, energy-conservation, safe, reliable, and simple in structure, easily to make, easily repair, cost is low, function is many, molten tea, bathes, is warmer than one, multi-use.
The utility model is achieved like this: flame is by the drum barrel, make " heat medium water " in the steam generator system at airtight, low temperature (96 ℃~99 ℃), negative pressure (0~-0.012MPa) state is vaporized down, is seethed with excitement, the steam of boiling is passed to the interior flowing water of spiral heat exchange tube (2) with heat, and water is heated the back and flows out.Meanwhile, steam is condensed into water and falls, and is heated boiling, vaporization once more.So Infinite Cyclic is finished above-mentioned phase transition process repeatedly.Economizer and upper drum are the thermal source difference in like manner, and the thermal source of economizer is the furnace outlet high-temperature flue gas.High-temperature flue gas enters economizer spiral smoke pipe (15), in the heating economizer " heat medium water ", and make its boiling, vaporization, heat is passed to recirculated water in the economizer heat exchanger tube (12), recirculated water is heated the back for the first time by being pumped in the upper drum internally spiral heat-exchanging tube (1) in this pipe, be heated once more, at last high-temperature-hot-water delivered to hot user.
Be provided with a temperature adjustment water pipe (4) in the hydrospace, drum bottom,, boiler can be heated, can have a bath again, also can boil water, multi-use (tea, bath, warm) in order that, prevent overtemperature, superpressure and the usefulness that boils water with running water fine setting " heat medium water " temperature.
Spiral heat exchange tube (2), (12) and economizer spiral smoke pipe (15) as shown in Figure 2, all are to be pressed with dark equidistant helicla flute steel pipe such as outer recessed convex, in order that increase heat transfer area, improve water and flue gas flow condition in pipe, augmentation of heat transfer reduces incrustation, dust stratification in the pipe.
Owing to adopted such scheme, make the novel vacuum phase transition energy-saving safety hot-water boiler not only can be energy-efficient, and simple in structure, easily to make, easily repair, easy and simple to handle, more safe and reliable, function increases, multi-use.
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is structure of the present utility model and schematic diagram.
Fig. 2 is spiral heat exchanging water pipe and spiral smoke pipe schematic diagram.
In the drawings: 1, heat-exchanger rig water outlet base; 2, spiral heat exchange tube; 3, pressure gauge stand; 4, temperature adjustment water pipe; 5, emergency valve seat; 6, emptying base; 7, filler pipe seat; 8, heat-exchanger rig entry base; 9, upper drum one economizer tube connector; 10, economizer heat-exchanger rig water outlet base; 11, economizer filler pipe seat; 12, economizer spiral heat exchange tube; 13, economizer emergency valve seat; 14, economizer heat-exchanger rig entry base; 15, economizer spiral smoke pipe.
In Fig. 1, by high-performance heat transfer components--the steel shell and tube spiral grooved tube heat-exchanger rig of two kinds of specifications that spiral heat exchange tube (2) and economizer spiral heat exchange tube (12) constitute respectively, place the first half space of upper drum and economizer respectively, middle by pipe (9) connection, recirculated water is under the promotion of pump, enter by economizer heat-exchanger rig entry base (14), through (12), (9) and (2), flow out by heat-exchanger rig water outlet base (1), be heated for twice in the way, at last, bring the user high-temperature water.High-temperature flue gas is emitted heat from the interior process of economizer spiral smoke pipe (15), and " heat medium water " in the heating economizer makes its boiling, vaporization, and the recirculated water in the economizer spiral heat exchange tube (12) is added for the first time
Be arranged on the temperature adjustment water pipe (4) in the upper drum hydrospace, an end is connected with running water pipe, and the other end is in parallel with pump entry and tea bucket, and both fine-tuning " heat medium water " temperature can boil water multi-use again.

Claims (3)

1, a kind of follow-on hot-water boiler mainly is to be made of upper drum and economizer two parts, low-temperature boiling, negative pressure operation, phase-change heat transfer, it is characterized in that: the first half vapor space of upper drum and economizer, a steel shell and tube spiral grooved tube heat-exchanger rig has been installed respectively.
