Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to preferred embodiments. However, it should be noted that the numerous details set forth in the description are merely intended to provide a thorough understanding of one or more aspects of the present invention, even though such aspects of the invention may be practiced without these specific details.
A method for improving the digestion temperature and promoting the digestion process of light calcium carbonate by utilizing a photo-thermal technology converts solar energy into heat energy to heat water for digestion, and simultaneously carries out heat preservation treatment on the outer wall of a digestion kiln to reduce heat loss, thereby achieving the aims of efficiently utilizing energy and improving the digestion rate of lime and water.
According to the principle of solar vacuum heat collecting tubes, a digestion kiln is designed into a large-scale solar vacuum heat collecting tube which mainly comprises a heat absorbing tube and a vacuum glass tube. The heat absorbing body and the vacuum tube are made of metal materials, and can operate at high temperature and under pressure, the operating temperature is 100-400 ℃, and the temperature required by water vapor digestion can be met. The surface of the heat absorbing pipe is coated with a selective absorbing coating, and the inner wall of the glass tube is coated with a light-gathering material coating.
Firstly, arranging a part of water in a slaking kiln, which is in contact with lime for slaking, as a metal heat absorption pipe, and communicating one end of the metal heat absorption pipe to form a fluid flow channel;
then, coating a selective absorption coating on the surface of the metal heat absorption pipe, wherein the selective absorption coating is basically divided into two parts, namely an infrared reflection bottom layer (high-infrared-reflectance metal such as copper, aluminum and the like) and a solar spectrum absorption layer (metal compound or metal composite material);
then, a double-layer vacuum glass sleeve is sleeved below the metal heat conduction pipe, and a reflecting film is coated on the inner wall of the glass tube below the heat absorption tube for light condensation.
The invention has the characteristic of one-way heat transfer technically, and both ends between the metal heat absorption tube and the glass tube need to be sealed, so that the heat absorption tube needs to be in transition by means of the corrugated tube in order to compensate for the expansion caused by heat and contraction caused by cold. Therefore, the integral heat preservation performance is excellent.
The light calcium slaking kiln is designed into a large-scale metal vacuum heat collecting pipe. In order to meet the working environment of the digestion process, the vacuum heat collecting tube mainly comprises an inner metal heat absorbing body and an outer layer of glass tube. The surface of the heat absorber is deposited with a spectrally selective absorbing coating by various means. Because the interlayer between the heat absorber and the glass tube keeps high vacuum degree, the heat loss of conduction and convection of air in the vacuum tube can be effectively inhibited; since the selective absorption coating has low infrared emissivity, the radiation heat loss of the heat absorbing plate can be obviously reduced. The solar water heater can utilize solar energy to the maximum extent in the digestion kiln, heat the water for digestion and improve the digestion efficiency.
The device production process mainly comprises the following steps:
1. manufacturing steel pipes and glass pipes and performing cleaning pretreatment; the heat collecting tube for the digestion kiln is required to be subjected to high-temperature steam corrosion for a long time, high-temperature resistant steel materials are required to be selected and used, the thickness of the heat collecting tube is more than 16mm, and the glass tube is made of borosilicate glass;
2. the surface of the steel pipe is coated with a selective absorption film by adopting multi-target co-sputtering, so that the sunlight absorption rate is more than 95 percent, and the black body emissivity is less than or equal to 5 percent;
3. coating an antireflection film on the surface of the glass tube to increase the light transmittance from 89% to 97%;
4. welding a metal corrugated pipe and a steel pipe, and then connecting a glass pipe and the corrugated pipe;
5. pumping the gas between the steel tube and the glass tube to meet the vacuum requirement, and sealing at the exhaust port;
6. the glass tube is annealed.
The front end of the slaking kiln is provided with an inner sleeve, lime and slaking water simultaneously enter, and slaked lime milk flows out from a jacket between the inner sleeve at the front end and the cylinder body. The rotary screen for screening ash and slag is installed at the back of the digesting kiln, and under the propelling action of the rotation of the drum, the ash and slag move to the back of the drum, and the ash and slag are washed with water after entering the rotary screen and finally discharged from the back end.
Both the temperature of the lime and the temperature of the water used for slaking affect the rate of slaking of the lime. It is known that the lime digestion reaction is strongly exothermic and that 1kg of pure calcium oxide will digest it with sufficient heat to heat 2.8kg of water from 0 c to 100 c, so that too high a temperature will inhibit the reaction. However, from the viewpoint of dynamics, the higher the temperature, the larger the reaction rate constant and the higher the reaction rate. From the water vapor equilibrium pressure at different temperatures during calcium oxide digestion, it can be known that the digestion reaction temperature is in the range from normal temperature to 300 ℃, and the higher the temperature is, the faster the reaction speed is.
The temperature of the water for digestion is higher, the physical form is more gaseous, and the digestion effect is better when the lime is contacted with the water for digestion compared with the prior art (the hot water for digestion from a kiln gas cooling and purifying section with the temperature of 55-65 ℃). The heat preservation device who adopts, the metal outer wall of contrast prior art makes the inside temperature of digestion kiln more stable, and the ripe thick liquid (calcium hydroxide) after the digestion can not cause the quality change because of the temperature change. Meanwhile, the heat loss caused by the temperature difference between the inside and the outside of the digestion kiln is reduced.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
