Abstract
The invention discloses a solar greenhouse for wood stoving, and mainly relates to wood drying and stoving equipment. The solar greenhouse mainly comprises a light collecting lens, a focal light collecting block, an optical fiber, a diffusion optical fiber, absorber plates, a housing and a chimney. The sunlight is collected on the focal light collecting block by virtue of the light collecting lens, and is propagated to the diffusion optical fiber through the optical fiber. The diffusion optical fiber is internally doped with reflecting sequins, and the light can be refracted onto the absorber plates to heat the absorber plates for stoving operation over wood. The wood is arranged on the two sides of the absorber plates and/or an ultrasonic generator. The absorber plates and the ultrasonic generator can act on the wood at the same time, and can also independently play a role in stoving the wood, so that the application range of the solar greenhouse is expanded, and wood drying efficiency is improved. The sunlight is directly focused, so that the utilization rate of the sunlight is increased. The focused light is propagated into stoving greenhouse for light-heat conversion through the optical fiber, so that the utilization efficiency of solar energy is improved. Due to the use of the optical fiber, the absorber plates can be arranged more conveniently. The solar greenhouse can run without energy consumption under the condition of sufficient light.
Description
Technical field
The present invention relates generally to the drying of wood, drying plant, especially timber stoving solar energy greenhouse.
Background technology
Trees are from felling to the final process utilized, and because the moisture content of the timber of newly cutting down is often very high, timber is carried out drying process by a requisite step exactly.The drying of wood is the critical process in timber processing, plays vital effect to improve in the quality of woodwork and process energy-saving and cost-reducing.
In order to save energy consumption during drying, usually to carry out air drying (doing referred to as gas) pretreatment to it, the moisture content of timber is reduced to a certain degree.And gas intervenes processing method, often need the time spending the several months.Also need to take a lot of storage areas.
Now fairly large wood product industry, is all put in drier by timber, reaches effect fast by methods such as heating, but the time that this kind of method generally also will expend several weeks could obtain the timber of sufficiently dry.In prior art, not only timber is heated, also pressurize, while timber is dried, the density of timber can also be improved, thus improve intensity and the hardness of timber, there is certain advance.Be in the patent of invention of 201310121210.1 at application number, the method for employing timber is carried out a certain proportion of compression, such as 40%, thus therefrom squeezed out by moisture.
But drying of wood energy consumption is too high, account for the 40-70% of timber power consumption of polymer processing, and the thermal efficiency of drying is generally on the low side, usually only between 30-40%; In addition, the pollution that dry run causes is usually again the important sources that Chinese environmental pollutes.
Utilizing ultrasonic wave to carry out dry materials is an emerging dry technology, can faster dried material at a lower temperature.Such as: the utility model patent of patent No. ZL200920047237.X discloses a kind of ultrasonic hot air combined dryer, and this device is applicable to the drying of mud, coal, agricultural product, food and medicine.But it is little that this device can only be used for dry bulk, graininess or powder material, and also in processing procedure, ultrasonic energy utilization rate is low, is unfavorable for that internal batch moisture evaporates.
Utilize clean energy resource to carry out drying, an importance utilizes solar energy.Utilizing the important channel of solar energy, is utilize opto-electronic conversion, utilizes solar panel to produce electric energy, thus again utilizes electric energy to be converted to heat energy.In 200810085104.1 patents, by solar energy by fluid heating, by fluid, heat is being delivered to timber baking zone to be heated, thus the heating completed timber, but need a photothermal deformation, after converting, also need fluid media (medium) to complete the transmission of heat, systematic comparison is complicated.The patent No. is the patent of 201010252779.8, utilizes heat collector, and the sunlight be radiated at outside hothouse is carried out photothermal deformation and passes to hothouse again, but Problems existing is, sunlight irradiated area is limited, and thermal-arrest finite energy can not meet oven dry demand.
Above-mentioned prior art, Problems existing, mainly contains: energy consumption is high; Utilize solar energy efficiency low, mostly be secondary and utilize; Solar use amount is little, can not meet oven dry demand.
