Abstract
The utility model relates to a secondary evaporation type dry steam boiler. The boiler comprises a boiler body and a heating unit heating the interior of the boiler body. A water injection port and a steam outlet are arranged on the boiler body, a boiler steam cavity is arranged in the boiler body, a secondary evaporator is arranged in the boiler steam cavity, and a gas secondary evaporation cavity is arranged in the secondary evaporator. A partition heating plate is arranged in the secondary evaporation cavity, an inlet and an outlet are arranged on the secondary evaporator, the inlet of the secondary evaporator is communicated with the boiler steam cavity, and the outlet of the secondary evaporator is communicated with the steam outlet. Steam in the boiler steam cavity is heated by the partition heating plate in the secondary evaporation cavity and evaporated twice before discharges by the steam outlet. The arrangement of the secondary evaporator in the boiler steam cavity makes steam in the boiler evaporated twice when passes through the secondary evaporator before discharges by the steam outlet. Thus, steam sprayed by the steam outlet is dry steam.
Description
Technical field
The utility model relates to a kind of dry saturated steam boiler.
Background technology
By in boiler, supplying water,, provide the boiler of dry saturated steam to be widely used to load device by heating.When boiler is used vapour, pressure meeting rapid drawdown in the boiler, cause the boiling point of water to descend, therefore rapid boiling can take place in water, and produces a large amount of steam bubbles, will increase the amount of steam small water droplets like this because of breaking of steam bubble, and also aggravation greatly of water level rising phenomenon, make the vapor space in the boiler reduce, the little water droplet that splashes is more prone to discharge by steam drain, increases the water amount in the steam.
The utility model content
At the problems referred to above, when providing a kind of giving vent to anger, the purpose of this utility model do not carry the dry saturated steam boiler of the water yield secretly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double evaporation-cooling formula dry saturated steam boiler, comprise boiler body, the heating unit that described boiler body inside is heated, described boiler body is provided with water filling port and steam (vapor) outlet, the inside of described boiler body forms the Boiler Steam chamber, the inside in described Boiler Steam chamber is equipped with revaporizer, the inside of this revaporizer forms gas double evaporation-cooling chamber, described double evaporation-cooling is provided with the obstruct heating plate in the chamber, described revaporizer is provided with entrance and exit, the inlet of described revaporizer is connected with described Boiler Steam chamber, the outlet of described revaporizer is connected with described steam (vapor) outlet, steam in the Boiler Steam chamber is before going out from described steam (vapor) outlet, thus obstruct heating plate heating the carrying out double evaporation-cooling in the described double evaporation-cooling of the process chamber.
Preferably, be provided with polylith in the described double evaporation-cooling chamber and intercept heating plate, the described obstruct heating plate of polylith is divided into the steam channel of a bending in the chamber internal resistance of described double evaporation-cooling, and an end of described steam channel is connected with the inlet of described revaporizer, the other end is connected with the outlet of described revaporizer.
Preferably, described obstruct heating plate indentation.
Preferably, described revaporizer adopts built on stilts mode to be fixed on the inside in described Boiler Steam chamber.
Preferably, be provided with coaming plate between described revaporizer and the described boiler evaporating chamber,, offer some apertures on the described coaming plate, described boiler evaporating chamber is connected by this aperture with described indirect steam chamber.
Because technique scheme utilization, the utility model compared with prior art has following advantage: by in the Boiler Steam chamber revaporizer being set, make steam in the boiler before going out from steam (vapor) outlet, carry out double evaporation-cooling through in the revaporizer.And owing to revaporizer is arranged in the boiler evaporating chamber, the temperature of revaporizer is very approaching with saturated-steam temperature like this, at steam from the process of double evaporation-cooling evaporation cavity, saturated vapor fully contacts with the obstruct heating plate, with vapour cavity pressure is descended owing to outside simultaneously, cause the boiling point of the water droplet in the steam to reduce, thereby can promptly the water droplet of carrying secretly in the saturated vapor be heated into steam, thereby significantly reduced the water droplet content in the steam, improved the mass dryness fraction of steam, what guaranteed the steam (vapor) outlet ejection is dry saturated steam.
Description of drawings
Accompanying drawing 1 is the main cutaway view of boiler of the present utility model;
Accompanying drawing 2 is the vertical view cutaway drawing of boiler of the present utility model;
Accompanying drawing 3 is looked cutaway view for the right side of boiler of the present utility model;
Accompanying drawing 4 is the enlarged drawing at accompanying drawing 3A place.
In the above accompanying drawing: 1, boiler body; 2, heating unit; 3, Boiler Steam chamber; 4, revaporizer; 5, intercept heating plate; 6, double evaporation-cooling chamber; 7, water filling port; 8, steam (vapor) outlet; 9, inlet; 10, outlet; 11, pressure detecting mouth; 12, steam channel; 13, water level viewer; 14, cross over pipe; 15, aperture.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Referring to the boiler shown in the accompanying drawing 1 to 3, the heating unit 2 that comprises boiler body 1, boiler body 1 inside is heated, boiler body 1 is provided with water filling port 7 and steam (vapor) outlet 8, the inside of boiler body 1 forms Boiler Steam chamber 3, the inside in Boiler Steam chamber 3 is equipped with revaporizer 4, and revaporizer 4 adopts built on stilts mode to be fixed on the inside in Boiler Steam chamber 3.The inside of revaporizer 4 forms double evaporation-cooling chamber 6, be provided with the polylith indentation in the double evaporation-cooling chamber 4 and intercept heating plate 5, polylith intercepts heating plate 5 and is divided into the steam channel 12 of a bending in 4 internal resistances of double evaporation-cooling chamber, and steam channel 12 1 ends are connected with the inlet 9 of revaporizer 4, the other end is connected with the outlet 10 of revaporizer 4.Revaporizer 4 is provided with inlet 9 and outlet 10, the inlet 9 of revaporizer 4 is connected with Boiler Steam chamber 3, the outlet 10 of revaporizer 4 is connected with steam (vapor) outlet 8, steam in the Boiler Steam chamber 3 is before going out from steam (vapor) outlet 8, thereby double evaporation-cooling is carried out in 5 heating through the obstruct heating plate in the double evaporation-cooling chamber 6.
