Abstract
The invention relates to a steam generating process and device that is featured by several flue gas channels vertically running through the close vessel filled with water to the fuel gas generating system at the bottom. The fuel gas channel positioned inside the vessel is composed of three fuel gas subchannel groups and connected to the steam output above the water surface and the high temperature fuel gas generated by the fuel gas generating device is conducted to the fuel gas channels to boil the water to steam via heat exchange. The generated steam is conducted from the space below the water surface to the space above, undergoes heat exchange, acquires heat energy furthermore to become dry steam with less water drops and is expelled from the steam output. This invention has the advantage of low investment and cost, less water drops in the generated micro-pressure steam.
Description
Technical field:
The present invention relates to a kind of production of steam method and device.
Background technology:
The method of existing production minute-pressure steam or be to go out behind the high steam again by boiler for producing that decompression obtains, or be directly with one pot of boiled acquisition of water.Before adopting during a kind of mode, owing to be to become minute-pressure by high pressure, under the high pressure condition, devices needed expense and operating cost height; When adopting a kind of mode in back, can be entrained with a large amount of water droplets in the steam, make steam not reach instructions for use, though some inventor adopts the coiled flue that the water in the container is heated, to promote the evaporation of water amount, reduce the content of water droplet in the steam, still, the coiled flue is unfavorable for that the acceleration of flue gas is mobile, influence the flow of flue gas, thereby influenced the total heat energy that flue gas brings water.
Summary of the invention:
Goal of the invention of the present invention is to provide that a kind of investment, operating cost are low, the method and the device of the poor production steam of water droplet in the minute-pressure steam.
The method of production steam of the present invention is to realize like this, the exhaust gases passes group that runs through on container and the through base burning flue gas process units vertically is set in the container of the sealing of filling water earlier, the exhaust gases passes group that is positioned at container is made of three groups of flue gas sub channel groups, first group of flue gas sub channel group bottom gas approach is connected with base burning flue gas process units, the top exhanst gas outlet is connected with second group of flue gas sub channel group top gas approach, second group of flue gas sub channel group bottom exhanst gas outlet is connected with the 3rd group of flue gas sub channel group bottom gas approach, the 3rd group of flue gas sub channel group top exhanst gas outlet is connected with atmosphere, space on the water surface connects steam (vapor) outlet, then, the high-temperature flue gas that the combustion product gases process units is produced imports to exhaust gases passes, by heat exchange, with the boiled generation steam of the water in the container, the steam that is produced is by the space more than the importing of the space below the container water surface water surface, and carry out heat exchange with the exhaust gases passes in the above space of the water surface, making steam further obtain heat energy becomes the higher dry saturated steam of free of water droplets temperature seldom, sends out by steam (vapor) outlet at last.Because the exhaust gases passes that adopts vertical three groups of flue gas sub channel groups by being interconnected to constitute heats the water in the container, and, steam passes through post bake, like this, flue gas can flow in exhaust gases passes smoothly and apace, assurance has enough flue gas supply heat energy to give water in the container and the steam that is produced, steam is through post bake, guaranteed the quality of steam, simultaneously, owing to increased the length in the water of exhaust gases passes in container, flue gas heat energy can be absorbed by water fully, improved the thermal efficiency.Since the steam minute-pressure of being produced even do not have pressure, therefore.Equipment investment is few, and operating cost is low.
Here, in order to guarantee that further the steam of being produced is dry saturated steam, container on the water surface is separated into the space of two or more intercommunications, steam (vapor) outlet is positioned at uppermost space, the following steam that is produced of the water surface becomes dry saturated steam by the further heating of the exhaust gases passes in the space of two or more above intercommunications of the water surface.
In order to prevent that in the fouling of exhaust gases passes outer surface water is the water after handling through decationizing.
The device of production steam of the present invention is to realize like this, by the sealing water receptacle that has steam (vapor) outlet, vertically run through the exhaust gases passes group with good heat conductive performance of sealing water receptacle, be arranged on the combustion gas fire row of sealing water receptacle bottom, the extra feed tank that has water-level control apparatus that is connected with the sealing water receptacle constitutes, the exhaust gases passes group that is positioned at the sealing water receptacle is made of three groups of flue gas sub channel groups, first group of flue gas sub channel group bottom gas approach is connected with bottom combustion gas fire row, the top exhanst gas outlet is connected with second group of flue gas sub channel group top gas approach, second group of flue gas sub channel group bottom exhanst gas outlet is connected with the 3rd group of flue gas sub channel group bottom gas approach, and the 3rd group of flue gas sub channel group top exhanst gas outlet is connected with atmosphere.During work, arrange to exhaust gases passes group supplying high temperature flue gas by the combustion gas fire, the blast tube group will be sealed the water ebuillition of heated in the water receptacle, and the steam that is produced enters becomes the good dry saturated steam seldom of free of water droplets after the post bake through the blast tube group in the interlayer, see off by steam (vapor) outlet then.The water yield that extra feed tank then reduces because of the steam evaporation to the water receptacle supply.Adopt extra feed tank, can accurately control the water level in the sealing water receptacle, preventing influences Water Level Control because of the boiling of water in the sealing water receptacle.
Above the water level in the sealing water receptacle one or more layers of interlayer is set, the cavity volume of interlayer below sealing water receptacle is connected, and steam (vapor) outlet is positioned on the uppermost interlayer of sealing water receptacle.
In order to quicken heat exchange, the exhaust gases passes group is provided with wing plate.The effect of wing plate had both increased heat exchange area, can force the water lateral flow simultaneously, to reduce the detention layer of exhaust gases passes group surface water, the carrying out that quickens heat exchange.
In order to prevent fouling, extra feed tank is connected with water treatment facilities, and water treatment facilities is the cationic ion-exchange resin device.Enter the preheating water tank behind the cation in the external water process water treatment facilities removing water,, therefore, prevent effectively that at high temperature incrustation scale from occurring because the cation in the water is eliminated.
Make for convenience, on the sealing water receptacle, below be respectively arranged with first group of flue gas sub channel group, second group of flue gas sub channel group and second group of flue gas sub channel group, the 3rd group of airtight cavity volume that the flue gas sub channel group is communicated with.
The heat energy that is scattered and disappeared when making full use of the airtight cavity volume of high-temperature flue gas by first group of flue gas sub channel group, second group of flue gas sub channel group are communicated with, airtight cavity volume is to make with the good material of heat conductivility (as stainless steel), airtight cavity volume is provided with the preheating water tank who has water-level control apparatus, preheating water tank's water inlet links to each other with water treatment facilities, and delivery port links to each other with extra feed tank.
Compared with the prior art the present invention has that investment, operating cost are low, a poor advantage of water droplet in the minute-pressure steam produced.
