Seal connecting method of porous ceramic plate column

Abstract

The invention provides a sealing connection method used for longitudinal lines of porous ceramic plates, comprising the steps as follows: normal ceramics is used as raw material; a porous ceramic plate biscuit with the substrate of normal ceramic is prepared by a vacuum extrusion method; subsequently, the surface of the porous ceramic biscuit is covered by black porcelain slurry and sintered to be a black porcelain composite porous ceramic plate; alternatively, the normal ceramics raw material is mixed with the black porcelain raw material to prepare the wholly black porous ceramic plate; ceramic material, inorganic material, organic material and metal material are used for preparing a U-shaped connection interface, a U-shaped transitional connection interface and a collecting port which are combined into the longitudinal lines of the porous ceramic plates by a sealing adhesive; the fluid in a passage is sealed by the sealing adhesive in the three groups of parallel surfaces in U-shape so as to lead all parts to form convenient, economical and reliable sealing and connection; and the longitudinal lines of the porous ceramic plate can be used for collecting solar energy, far-infrared radiation and heat dissipation of building heating.

Description

(1) Technical field [0001] The invention relates to the technical field of ceramic manufacturing and application of ceramic products, in particular, adopts the method of ∪-shaped sealing connection to combine porous ceramic plates into a column of porous ceramic plates. (2) Background technology [0002] After nearly 200 years of continuous accelerated mining, fossil fuel resources such as coal, oil, and natural gas have been gradually exhausted. Now we must find at least one new large-scale alternative energy within a limited time. Like nuclear fusion, deep-sea combustible hydrates, space solar power plants, low-cost solar cells, etc., the extensive application of low-cost, long-life solar collectors can also form new large-scale alternative energy sources. [0003] The current consensus in the scientific community is that the total amount of solar radiant energy reaching the earth's land surface is tens of thousands of times greater than the total amount of energy consumed...

AI Technical Summary

Problems solved by technology

Both have the following disadvantages: 1. The metal tube-sheet heat collector mainly adopts materials such as copper and aluminum, and the structure and manufacturing process of the vacuum glass tube heat collector are relatively complicated. high

2. Both of them use black sunlight absorbing paint coated at low temperature. Under the long-term sunlight, there will be a certain degree of aging to attenuate the sunlight absorption rate, the metal is easy to corrode, and the vacuum degree in the vacuum glass tube will gradually decrease. Significant Cause of Lifetime and Efficiency Issues

[0012] 1. Usually the temperature difference between the inside and outside of the greenhouse is about 30°C, but when the solar collector is air-dried, the temperature difference between the inside and outside can exceed 120°C. In contrast, the heat collection efficiency of the "solar chimney" is low, but the existing solar collectors The cost of the heater is too high, and the heat collector of the vacuum glass tube is a blind tube closed at one end, which makes it difficult to form a smooth air flow, which also makes the application difficult

[0013] 2. The chimney with a diameter of 130m and a height of 1000m is currently the tallest man-made building, and the technical and construction difficulties in the construction process may result in a higher cost

[0017] 2. The exploration cost of deep geothermal resources is high, and the drilling success rate is low

[0018] 3. The drilling depth is often more than 1000m, in order to maintain production capacity and maintain the environment must achieve 100% recharge, which increases the cost

[0019] 4. Generally, geothermal fluids are corrosive and easy to scale, which increases operating costs and equipment costs

300×300 mm vanadium-titanium black porcelain solar panels have an area of ​​0.09 square meters and a water capacity of 0.9kg. The water temperature can reach 100°C when the single-layer glass veneer is sun-drenched. In 1987, the vanadium-titanium black was ranked among the top solar water heaters in Shandong Province. Porcelain solar water heaters won the first prize. The water quality of the vanadium-titanium black porcelain solar water heaters was tested before and after heating, and no visible changes were found. The solar panels that have been used for more than 10 years have no signs of fading, corrosion, or aging. The black porcelain hollow solar panel method has low molding efficiency, consumes a large amount of gypsum, and has a low yield of large-sized solar panels. There are too many joints for small-sized panels, and the installation is cumbersome. It is difficult to develop into a large-scale industrial production method, and it is difficult to achieve large-scale promotion and use.
