Abstract
The invention relates to a novel silicon carbide foam ceramic solar energy air heat absorber, which comprises a thermal insulation layer, wherein a silicon carbide foam ceramic receiver, which is a circular receiver with through-holes, is arranged at the inner part of the thermal insulation layer; and a flow guide device fixedly connected with a fan is arranged at one end of the thermal insulation layer. The novel silicon carbide foam ceramic solar energy air heat absorber has the advantages of simple structure, low manufacturing cost, even contact during heat exchange and good heat exchange effect.
Description
Technical field
The present invention relates to a kind of solar air heat absorber, be specifically related to silicon carbide foam ceramic solar energy air heat-absorbing device.
Background technology
Foam silicon carbide ceramics is as a kind of new function material; Has higher interconnected pore rate; And the essence that has kept silicon carbide ceramics to a certain extent; Have characteristics such as low-density, high-ratio surface, high-permeability, good high-temperature stability and thermal shock resistance, high chemical stability, long service life, therefore be suitable for the environment of high temperature, burn into oxidation.This pottery is used at first metal bath particularly in the filtration of high-melting-point alloy more; And along with going deep into to its research; Increasing function is developed; Make it can be used as high temperature filtration, purification, absorption, separation, catalysis, mixing, heat insulation and heat exchange device, use very extensively in industries such as metallurgy, chemical industry, machinery, environmental protection, the energy.
At present; Global resources are in short supply; And solar energy is inexhaustible regenerative resource, and the today of reduce year by year at fossil fuel, the international energy situation is severe day by day, development and use solar energy is one of important channel of realizing energy supply diversification, assurance energy security.
Up to now; Multiple hot generation modes such as tower, slot type, dish formula have been arranged, and wherein the tower type thermal generation device is the most competitive technique device, and its basic principle is to utilize numerous heliostats; Solar radiation is reflexed on the solar receiver that places on the tower; Produce superheated steam or high temperature air by heating working medium, drive generating set, produce electric energy.The high temperature solar heat dump is the core component of tower type thermal generation system.External carried out many research around this technology, mainly concentrated on the U.S., Spain, Germany, Israel etc., domesticly started late aspect this, achievement in research is also less.The high temperature solar heat dump roughly can be divided into two kinds of forms by structure type: the outside receives light type and cavity type.Wherein using more is the positive displacement heat dump, and a kind of exactly solar heat absorber that matrix constituted by three-dimensional can make the working fluid that therefrom flows through carry out direct heat exchange with it.The positive displacement solar heat dump has a hollow shell usually; Be used to hold the positive displacement solar absorption plant; Housing is covered by the glass light inlet window, forms the heat sink cavity of sealing, and cavity can hold the working fluid that directly contacts with absorption plant; Working fluid flows through the heat sink cavity, absorbs heat from absorption plant.Existing heat dump is had relatively high expectations to metal, system complex, and cost is high, and harsh to security requirement, the heat transfer sheet area of hot body is little, and heat transfer efficiency is not high, and adopts different materials as absorber and heat storage, complex structure.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure in order to overcome deficiency of the prior art, and low cost of manufacture contacts evenly the novel silicon carbide foam ceramic solar energy air heat-absorbing device of good effect of heat exchange during heat exchange.
Technical scheme: in order to solve the problems of the technologies described above; Novel silicon carbide foam ceramic solar energy air heat-absorbing device of the present invention; It comprises heat-insulation layer, is provided with the foam silicon carbide ceramics receiver in said heat-insulation layer inside, and said foam silicon carbide ceramics receiver is the receiver of circular band through hole; Be provided with guiding device at said heat-insulation layer one end, said guiding device is fixedly connected with blower fan.
Radiant heat flux and cold air get into said guiding device from said heat-insulation layer front portion through flow-guiding channel.
At least be provided with a said foam silicon carbide ceramics receiver in said heat-insulation layer inside.
Foam silicon carbide ceramics receiver of the present invention is the circular piece of the whole band of burr through hole, and during heat exchange, the area that contacts with each other is big between the foam silicon carbide ceramics receiver for said radiant heat flux and cold air, and heat exchange is even, good effect of heat exchange.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the present invention is simple in structure, low cost of manufacture, during heat exchange contact evenly, good effect of heat exchange.
