Abstract
The utility model discloses a steam / hot water combination supplying electrical vacuum boiler, which comprises a boiler barrel with an insulating sleeve and an electric heating device with a temperature controlled switch, wherein, the boiler barrel is filled with heat transfer medium, a heat exchanger is arranged in the boiler barrel, a vacuum pump is connected with the boiler barrel, and an output end of the vacuum pump is communicated with the atmosphere. The utility model is characterized in that the heat transfer medium is aqueous lithium bromide. The utility model has advantages of safety, high heat efficiency, one machine with multifunction and complete function, and the overpressure possibility is reduced.
Description
[technical field]
The utility model relates to a kind of electric boiler that steam and hot water can be provided simultaneously.
The vacuum hot water boiler that uses now is many to be working medium with water, is the building heating and supplies health hot water as central heating hot water unit.The indirect modes that adopt utilize water boiling point under vacuum state to reduce more, and twice heat exchange of---boiler water and steam---heat medium water of passing through flue gas makes heat medium water heat up complex structure.And some hotels, hospital also can provide low-pressure steam when requiring boiler that hot water is provided at present.Therefore, be necessary to design a kind of steam/heat water alliance, and the good vacuum electric boiler of security performance
[utility model content]
The purpose of this utility model is to provide a kind of security performance good, and the steam/heat water alliance vacuum electric boiler of hot water and low-pressure steam can be provided simultaneously.
The steam/heat water alliance vacuum electric boiler of the utility model design is achieved in that it comprises the drum of being with muff, the electric calorifie installation of band temperature detect switch (TDS), wherein be loaded with heat transfer medium in the drum, and embedded heat exchanger, one vavuum pump and drum join, its output communicates with atmosphere, it is characterized in that: heat transfer medium is a lithium-bromide solution.
Further improvement as such scheme is characterized in that: the concentration of lithium-bromide solution is greater than 55%.
Further improvement as such scheme is characterized in that: heat exchanger is the spiral coil that has fin.
Further improvement as such scheme is characterized in that: the outlet of heat exchange coil connects a steam heater, can free adjustment steam and hot water flow.
Operation principle of the present utility model and characteristics are described below:
One, safe and reliable, reduced the possibility of superpressure.The utility model adopts vavuum pump, and the heat transfer medium high lithium bromide salting liquid that is a kind of boiling point, because this medium has higher boiling point, and stable performance, nontoxic, pollution-free and corrosivity is little.And in heating process, the not enough 100Kpa of its solution absolute pressure is in vacuum negative pressure condition all the time in the boiler.When its concentration greater than 55% the time, boiling point is higher than 145 ℃.And the recirculated water in the coil pipe directly do not heat by high-temperature flue gas, can effectively reduce the fouling of casing and pipeline, keeps the unimpeded of pipeline, and recirculated water is kept clean.
Two, heat transfer efficiency height.Heat exchanger adopts with ribbing spiral coil, be immersed in the heat transfer medium, all the time keep at a certain temperature by heat transfer medium in the temperature detect switch (TDS) control boiler, because heat transfer medium has higher heat conductivity, and has the bigger temperature difference, heat transfer medium makes the water in the pipe reach boiling soon by the water generation heat exchange in the dish tube and tube.Because the coefficient of heat transfer is big, thereby required heat exchange area is little, the structure of unit is very compact.
Three, a tractor serves several purposes, multiple functional.This unit can heat, supply health hot water and steam, both can singly supply, but independent assortment supply again.Superheated steam reaches user's requirement by the flow of steam heater steam regulation and hot water.
[description of drawings]
Accompanying drawing is a structural representation of the present utility model.
[specific embodiment]
With reference to the accompanying drawings, a kind of steam/heat water alliance vacuum electric boiler of the utility model design, below the drum 2 of band muff, the electrical heating wire 8 of band temperature detect switch (TDS) is installed, be loaded with lithium-bromide solution in the drum 2 as heat transfer medium 3, the concentration of lithium-bromide solution is greater than 55% in the present embodiment, and its boiling point is higher than 145 ℃, has stable performance, nontoxic, pollution-free and characteristics that corrosivity is little.Drum 2 is built-in with heat exchanger 5, and this heat exchanger is formed by spiral coil 9 with attached to the fin on the spiral coil 9 10, and wherein spiral coil is made by copper pipe.Vavuum pump 1 joins with drum 2, and its output communicates with atmosphere.Water inlet pipe is connected with coil pipe with check-valves 6 by force (forcing) pump 7.The outlet of coil pipe 9 connects a steam heater 4, can free adjustment steam and hot water flow by this blender.
Certainly the selection of spiral coil is not limited to copper pipe, can also be stainless steel or carbon steel pipe etc.
