Abstract

The utility model relates to a heat exchange boiler capable of converting fuel oil gas phase into vacuum, which mainly comprises a boiler barrel, wherein the lower part of the boiler barrel is provided with a burning chamber one of which is provided with an opening and the wall is provided with a burner over against the burning chamber. The opening of the burning chamber is communicated with a return burning chamber which is communicated with a smoke vent opening by a group of convection smoke pipes. The burning chamber, the return burning chamber and the convection smoke pipes are made of heat transfer materials and are submerged in heating medium water. A vacuum chamber is arranged above the heat medium water, and a heat exchanger pipe which is arranged in the vacuum chamber is respectively communicated with a circulating hot water inlet and a circulating hot water outlet. The utility model has the advantages of complete burning and energy saving with the adoption of a return burning structure, and a machine group adopts a wet back type and a fire pipe structure; the inner part of the machine group is in a negative pressure state in the process of operation, the dangers of expansion, explosion and rupture do not exist, and the constant quantity of the heat medium water is kept so as to ensure the machine group not to have no danger of burning idly; the heating medium water in the boiler is pure water which is completely deoxidized, and the boiler is not corroded in an oxygen-free mode and is not scaled so that the service life of the boiler is extended by 2 to 3 times.

Description

A kind of fuel vapor phase transformation vacuum heat exchange boiler

Technical field

The utility model relates to a kind of vacuum hot water boiler, particularly a kind of fuel vapor phase transformation vacuum heat exchange boiler.

Background technology

Phase transformation vacuum heat exchange boiler is to utilize water under the different pressures state, and the principle that its evaporating temperature is also different comes water is heated; When being evacuated in the boiler, heat medium water (high-purity water adds corrosion inhibiter or certain density lithium bromide water solution) is heated to boiling under vacuum state, produce the saturated vapor under the relevant pressure, this steam is the flowing water in the heating tube in heat exchanger, the hot water of the uniform temperature that the generation user needs.The heat medium water of phase transformation vacuum heat exchange boiler is under vacuum state, and boiling, condensation in pot circulate at the pot inner sealing, and when normal operation, heat medium water does not have consume; Do not have level fluctuation yet, do not have the danger of dry combustion method; Heat medium water is a high-purity water, and non flouling behaviour in boiler does not pollute heating surface, thereby can not cause the heat decay that boiler produces; It is long that phase transformation vacuum heat exchange boiler has the efficient high life, pollutes characteristics such as few and safe in utilization.Present phase transformation vacuum heat exchange boiler unreasonable structure, fuel vapor be fully burning, and efficiency of combustion is low, causes energy waste.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of rational in infrastructure, fuel vapor phase transformation vacuum heat exchange boiler that energy utilization rate is high is provided.

The utility model solves the technical scheme that its technical problem adopts: this fuel vapor phase transformation vacuum heat exchange boiler, mainly comprise drum, and be equipped with the combustion chamber of an end opening in the bottom of drum, be provided with over against the burner at combustion chamber openings place at the drum wall; The opening of combustion chamber communicates with the chamber of strile-bacing, and this chamber of strile-bacing communicates with exhaust opening by one group of convection current smoke pipe; Combustion chamber, the chamber of strile-bacing, convection current smoke pipe are made by heat-transfer matcrial, and are dipped in the heat medium water; The heat medium water top is a vacuum chamber, and this vacuum chamber is built-in with Tube Sheet of Heat Exchanger, and Tube Sheet of Heat Exchanger is imported and exported with circulating hot water and communicated.

The effect that the utility model is useful is: 1) rational in infrastructure, adopt the structure of strile-bacing, and sufficient combustion is saved the energy; Unit adopts wetting back-type, the fire tube structure, and combustion heat energy is fully utilized.Unit inside is in negative pressure state, the danger of do not have expansion, explode, breaking when 2) moving; The heat medium water that keeps constant in the machine guarantees that unit does not have empty danger of burning; Machine is assembled with the maltilevel security protective device, guarantees that unit operation is safe and reliable.3) heat medium water in the stove, in the overall process of boiler operatiopn, do not advance, do not go out, do not increase, do not subtract, be enclosed in the vacuum chamber of unit, transmit heat between the heat-transfer pipe of unit and heat exchanger, the heat medium water in the stove is the pure water of complete deoxidation, oxygenless corrosion, scaling does not make boiler life prolong 2-3 doubly.4) heating of vacuum hot water unit, heat supply water all adopt its built-in heat exchanger, heat exchanger internal pressure and boiler body steel construction are isolated fully, body is not subjected to the influence of hydrostatic pressing, and skyscraper heating and water supply need not be considered decompressor, the directly heating of 20-30 layer building, heat supply water.5) unit can provide hot water respectively for purposes such as heating or health hot waters; Bathing pool, the warm water swimming pool can be established closed circuit.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: burner 1, combustion chamber 2, the chamber 3 of strile-bacing, convection current smoke pipe 4, Tube Sheet of Heat Exchanger 5, circulating hot water imports and exports 6, exhaust opening 7, drum 8, heat medium water 9.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

This fuel vapor phase transformation vacuum heat exchange boiler mainly comprises drum 8, is equipped with the combustion chamber 2 of an end opening in the bottom of drum 8, is provided with the burner 1 of 2 opening parts over against the combustion chamber at drum 8 walls; The opening of combustion chamber 2 communicates with the chamber 3 of strile-bacing, and this chamber 3 of strile-bacing communicates with exhaust opening 7 by one group of convection current smoke pipe 4; Convection current smoke pipe 4 is built-in with spoiler.Make by heat-transfer matcrial combustion chamber 2, the chamber 3 of strile-bacing, convection current smoke pipe 4, and be dipped in the heat medium water 9; Heat medium water 9 tops are vacuum chambers 10, and this vacuum chamber 10 is built-in with Tube Sheet of Heat Exchanger 5, and Tube Sheet of Heat Exchanger 5 is imported and exported 6 with circulating hot water and communicated.

When operation, will be evacuated in the drum 8.Fuel sprays into combustion chamber 2 burnings through burner 1, the high-temperature flue gas that produces carries out strong radiation heat release to combustion chamber 2 walls, 2 walls refluxed along the combustion chamber after high-temperature flue gas ran into combustion chamber 2 rear walls, flue gas further carries out radiation and heat convection to the combustion chamber in the reflux course, this is after opening enters the chamber 3 of strile-bacing by convection current smoke pipe 4 convection heat transfers, after exhaust opening 7 discharge out of the furnace.Through the backhaul burning, fuel can fully burn, and makes full use of heat energy.Heat medium water 9 in the drum 8 seethes with excitement under vacuum state after absorbing heat, produces the saturated vapor under the corresponding pressure, and this steam is to condense in Tube Sheet of Heat Exchanger 5, and heat is passed to the interior flowing water of pipe, thereby produces the hot water under the uniform temperature; After the steam after Tube Sheet of Heat Exchanger 5 heat exchange is condensed into liquid, fall, burned again device 1 is heated into steam.Whole boiling, condensation process all are to circulate at drum 8 inner sealings.
