Abstract
A method and the related device for producing steam is provided, which is characterized in that: a closed container filled with water is vertically provided with a plurality of flue gas channels passing through the container and directly reaching to the bottom where a device for producing combustion flue gas is arranged, the container on the water surface is divided into two or more intercommunicated spaces, the uppermost space is connected with a steam outlet, the high-temperature flue gas produced by the device for producing combustion flue gas is conducted into the flue gas channel, the water in the container is boiled up to produce steam through the heat exchange, the produced steam is conducted from the lower space of the container into the upper space and implements the heat exchange with the flue gas channel of the upper space in order to facilitate the steam further gain the heat energy and become the dry steam with less water drips and higher temperature, and finally the steam is sent out through the steam outlet. Compared with the prior art, the invention has the advantages of low investment and running cost, and producing the micro-pressure steam with less water drips.
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, several exhaust gases passes that run through on container and the through base burning flue gas process units vertically are set in the container of the sealing of filling water earlier, then the container on the water surface is separated into the space of two or more intercommunications, connect steam (vapor) outlet in uppermost space, 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, space above the space of the steam that is produced below container imports, and carry out heat exchange with the exhaust gases passes of upper space, 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.Owing to adopt vertical exhaust gases passes that the water in the container is heated, 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, and steam has guaranteed the quality of steam through post bake.Since the steam minute-pressure of being produced even do not have pressure, therefore.Equipment investment is few, and operating cost is low.
In order to make full use of heat energy, produce flue gas behind the steam and import to being vertically set in the exhaust gases passes in the water preheat container in the water preheat container water in the water preheat container is carried out preheating.
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 water receptacle, the combustion gas fire row who is arranged on water receptacle bottom, the extra feed tank that has water-level control apparatus that is connected with water receptacle and constitute, one or more layers of interlayer is set above the water level in water receptacle, interlayer is connected with cavity volume below the water receptacle, and steam (vapor) outlet is positioned on the uppermost interlayer of water receptacle.During work, arrange to exhaust gases passes group supplying high temperature flue gas by the combustion gas fire, the blast tube group is with 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 water receptacle, preventing influences Water Level Control because of the boiling of water in the 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 surface water, the carrying out that quickens heat exchange.
In order to make full use of heat energy, the preheating water tank is set on water receptacle, the exhaust gases passes group with good heat conductive performance that the preheating water tank by the water tank that has water-level control apparatus, is vertically run through water tank constitutes, exhaust gases passes group on the preheating water tank is connected with exhaust gases passes group on the water receptacle, and the preheating water tank is connected with extra feed tank.During work, the flue gas with uniform temperature that the exhaust gases passes group from water receptacle is come out enters the water in the exhaust gases passes group preheating preheating water tank on the preheating water tank, is fed to extra feed tank through the water after the preheating.
In order to prevent fouling, the preheating water 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.
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.
