Description

本発明は熱交換装置、特に熱交換用被覆層付き蓄熱体に関するものである。   The present invention relates to a heat exchange device, and more particularly to a heat storage body with a heat exchange coating layer.

冶金、機械等の工業分野、農産物加工業において、熱交換器が広く使用されている。空気やガスを加熱するのは熱交換器の主な機能である。その中、ひとつの方法は直接石炭、ガス、石油、電気を熱源とする。もうひとつの方法は、余熱を熱源とする。   Heat exchangers are widely used in industrial fields such as metallurgy and machinery, and in the agricultural product processing industry. Heating air and gas is the main function of the heat exchanger. One method uses coal, gas, oil, and electricity as heat sources. Another method uses residual heat as a heat source.

まず熱源にて熱交換器の蓄熱体を熱する、その後、熱した蓄熱体を加熱したい対象の空気又はガス中に入れ、蓄熱体が空気又はガスとの熱交換により、蓄熱体の熱エネルギーが吸いあげられ、空気又はガスを加熱する目的に至る。通常、蓄熱体は一般的に耐熱材質、セラミックス材質、あるいは鋼鉄材で出来ている。   First, the heat storage body of the heat exchanger is heated with a heat source, and then the heated heat storage body is put into the air or gas of the target to be heated, and the heat storage body heat exchanges with air or gas, so that the heat energy of the heat storage body Suctioned up to the purpose of heating air or gas. Usually, the heat storage body is generally made of a heat-resistant material, a ceramic material, or a steel material.

蓄熱体の吸熱、放熱能力は熱交換器の熱交換能力にとって重要な要素であり、省エネルギーにも直結している。熱交換器の熱交換効率をアップさせるため、特許CN2462326YやCN2313197Yのように、数多くの特許により熱交換器の構造に対して改善を行っている。但し、これまで高レベル輻射材質の被覆層を増加により蓄熱体の蓄熱能力を改善し、熱交換効率向上を図る熱交換器についての報道はなかった。
中国特許ＣＮ２４６２３２６Ｙ 中国特許ＣＮ２３１３１９７Ｙ The heat absorption and heat dissipation capacity of the heat storage element is an important element for the heat exchange capacity of the heat exchanger, and is directly linked to energy saving. In order to increase the heat exchange efficiency of the heat exchanger, the structure of the heat exchanger is improved by a number of patents such as patents CN2462326Y and CN2313197Y. However, there has been no report about a heat exchanger that improves the heat storage capacity of the heat storage body by increasing the coating layer of high-level radiation material and improves the heat exchange efficiency.
Chinese patent CN2462326Y Chinese patent CN23113197Y

本発明は従来技術の欠点を克服し、効果が優れ且つ省エネルギーの熱交換用被覆層付き蓄熱体を提供する。   The present invention overcomes the drawbacks of the prior art, and provides a heat storage body with a heat exchange coating layer that is highly effective and energy-saving.

本発明にて提供される熱交換用被覆層付き蓄熱体について、少なくとも一側面に高レベル輻射材質被覆層が塗布されること。
上記高レベル輻射材質の被覆層厚みは0.02乃至3mmである。 The heat storage body with a heat exchange coating layer provided in the present invention is coated with a high-level radiation material coating layer on at least one side surface.
The coating layer thickness of the high level radiation material is 0.02 to 3 mm.

上記高レベル輻射材質は蓄熱体本体より、吸収率、輻射率が高い。   The high level radiation material has higher absorption rate and radiation rate than the heat storage body.

それにより、高レベル放射性物質にはある利点がある。それはその吸収率及び放射率が、熱保持器の中心が出来ている基材より高いことである。   Thereby, the high level radioactive material has certain advantages. That is, its absorptance and emissivity are higher than the substrate on which the center of the heat retainer is made.

上記蓄熱体の形状はハニカム状、フィン状、ボール状、楕円状、板状の中、何れ一種の形状となる。   The shape of the heat storage body is any one of honeycomb, fin, ball, ellipse, and plate.

上記蓄熱体の内部に穴があり、その内部の穴の形状は円形、正方形、長方形、菱形、六角形、あるいは多辺形である。蓄熱体本体は耐熱材質、セラミックス材質又は鋼鉄材質で作られる。   There is a hole inside the heat storage body, and the shape of the hole inside the heat storage body is a circle, a square, a rectangle, a diamond, a hexagon, or a polygon. The heat storage body is made of a heat resistant material, a ceramic material or a steel material.

上記蓄熱体の切断面形状は円形、正方形、長方形、菱形、六角形或いは多辺形である。   The shape of the cut surface of the heat storage body is a circle, a square, a rectangle, a diamond, a hexagon, or a polygon.

上記高レベル輻射材質は、耐熱材質、セラミックス材質又は鋼鉄材質等で出来た蓄熱体の領域においてあらゆる高レベル輻射遠赤外材質に適用する。   The high-level radiation material is applied to all high-level radiation far-infrared materials in the region of a heat storage body made of a heat-resistant material, a ceramic material, a steel material, or the like.

上記高レベル輻射性物質の被覆層はペースト塗布、吹き付け塗装または含浸塗布等方式にて完成させ、被覆層が塗布された後、直接でも使用できるし、また、高温にて固まってから使用しても良い。   The above high-level radioactive material coating layer is completed by paste coating, spray coating or impregnation coating, etc., and can be used directly after the coating layer is applied, or it can be used after it has hardened at high temperature. Also good.

被覆層を塗布、吹き付け塗装または含浸塗布する前に、蓄熱体本体の表面に高温粘着剤を含む前処理液を塗布することにより、高レベル輻射性物質の被覆層が蓄熱体本体との間の粘着力をより一層アップすることができる。   Before the coating layer is applied, sprayed or impregnated, a pretreatment liquid containing a high-temperature adhesive is applied to the surface of the heat storage body, so that the coating layer of the high-level radioactive material is between the heat storage body. The adhesive force can be further increased.

上記前処理液はPA80というポリアミン硬化剤又はアルカリ金属ケイ酸塩を含む水溶液である。   The pretreatment liquid is an aqueous solution containing a polyamine curing agent PA80 or an alkali metal silicate.

高レベル輻射性物質被覆層に含まれる固体成分の粒径が20〜900nmになるように超微細化処理される。それらの処理より、高レベル輻射性物質被覆層が本体との付着力を向上させる。   Ultra-fine processing is performed so that the particle size of the solid component contained in the high-level radioactive material coating layer is 20 to 900 nm. Through these treatments, the high-level radioactive material coating layer improves the adhesion to the main body.

本発明は熱交換器の被覆層付き蓄熱体の表面に、蓄熱体本体材質より輻射率の高い高レベル輻射性物質を塗布することに適用する。本発明は熱交換器の吸熱及び放熱能力を向上させ、従来技術の熱交換器より、吸熱及び放熱が早く、蓄熱容量を増加し、熱交換温度上昇する効果がある。   The present invention is applied to the application of a high-level radiation material having a higher emissivity than the material of the heat storage body main body to the surface of the heat storage body with a coating layer of the heat exchanger. The present invention improves the heat absorption and heat dissipation capability of the heat exchanger, and has the effect of increasing heat storage capacity and increasing the heat exchange temperature, faster heat absorption and heat dissipation than conventional heat exchangers.

同時に、熱交換器の熱交換率を上げることで省エネルギーにも効果が得られる。特に、鋼鉄を生産する高炉熱風炉の格子煉瓦及び蓄熱ボールの表面に高レベル輻射性物質層を塗布する場合、熱風炉内の温度が均等になり、蓄熱容量が著しく増加される。これにより循環空気の温度を上げることができ、炉交換周期が短縮され、ガス消費量及び空気流量が低減される。これらの消費量が低減されることにより、更なる電気を節約することができる。   At the same time, it is possible to save energy by increasing the heat exchange rate of the heat exchanger. In particular, when a high-level radioactive material layer is applied to the surface of lattice bricks and heat storage balls of a blast furnace hot air furnace that produces steel, the temperature in the hot air furnace becomes uniform and the heat storage capacity is remarkably increased. Thereby, the temperature of circulating air can be raised, a furnace exchange period is shortened, and gas consumption and an air flow rate are reduced. By reducing these consumptions, further electricity can be saved.

また従来の風力タービンの型式を変更することができるため、コストダウンにも繋がる。尚、被覆層が蓄熱体の本体を保護する働きもある。 鉄鋼圧延蓄熱方式加熱炉の蓄熱体の表面にその高レベル輻射性物質被覆層を塗布しておけば、蓄熱箱内部の温度が大幅にアップすることができる。   Moreover, since the model of the conventional wind turbine can be changed, it leads also to a cost reduction. In addition, a coating layer also has a function which protects the main body of a thermal storage body. If the high-level radiation material coating layer is applied to the surface of the heat storage body of the steel rolling heat storage type heating furnace, the temperature inside the heat storage box can be significantly increased.
