Description
Technical field
The utility model relates to for the living beings such as wood fragments, stalk or straw or wood materials being broken into to the production equipment field of wood chip, wooden chaff or wood powder, and saying more specifically to rub in crushing process makes the wood materials that the wood chip temperature rises pulverize drying system.
Background technology
After the biological materials such as wood fragments, stalk or straw are broken into to wood chip, wooden chaff or wood powder, for being pressed into particle, recycled, as the biomass fuel steam pot, biomass power generation etc., be a kind of common and very important technological means of resource recycling again.General program is to the broken coarse sizing that carries out of various leftover pieces wood, then is placed in disintegrating machine and carries out fragmentation, makes wood chip, wooden chaff or wood powder, and then carries out deep processing.
While as wood chip, wooden chaff or the wood powder of the use of boiler combustion, carrying out the particle compacting, its water content is had to certain requirement, the water content that requires to be suppressed front wood chip, wooden chaff or wood powder at most can not be higher than 30%, and ordinary circumstance all requires the water content will be lower than 20%.So all will be dehydrated processing to it general when the biological materials such as wood fragments, stalk or straw are broken into to wood chip, wooden chaff or wood powder, modal mode is that the mode heated up by gas-heated is separated moisture.This is due to materials such as the wood fragments that reclaim by burning, stalk or straws, can produce high-temperature gas, then high-temperature gas is imported to the wood materials of in hothouse, needs being pulverized carries out heat drying, makes wood materials water content before being pulverized reach standard.But because the efficiency of gas heat-transfer is very low, wood materials is not before being pulverized in addition, need long heating just can make water content up to standard, and heating will likely cause wooden material surface to be burnt for a long time, and make the wood chip phosphorus content that processes too high.
The wood chip that prior art also can complete pulverizing is piled up in hothouse and carries out drying, but because the grain diameter of wood chip, wooden chaff or wood powder is very little, after making, be deposited in together, although the moisture on surface distributes very fast, but the moisture of the inside of piling up can't discharge completely, by wooden chaff wood chip, is reuptaked and causes half-finished water content not up to standard.This just need to be stirred in dry run, because particle is very little, moisture to distribute as much as possible, just need to stir for a long time, and this will affect the production efficiency of equipment greatly.Another major issue that this mode also should be noted that is, because particle is very little, the words wood chip of excess Temperature very easily is scorched, and makes the wood chip that processes undesirable, and therefore the temperature of heating again can not be too high, and this has caused again the decline of production efficiency.
So be generally that wood materials to not pulverizing carries out drying, even but be provided with hothouse, because high-temperature gas thermal losses in the process of guiding hothouse is very large, therefore often wood materials need to just can reach requirement back and forth through hothouse is several, the wood materials that produces the high-temperature gas burning is also quite a lot of, accounts for the wood materials of recovery greatly.The purpose of original burning reclaimed materials is fuel saving, but, because heat conducting efficiency is very low, causes on the contrary fuel to damage greatly and improve, and a large amount of burnings also brings environmental pollution to a certain degree in addition, with the original intention of waste product utilization, disagrees.
Therefore in practical application, the producer generally shines in advance to the wood materials of returning, and by spreading out, adopts the mode at sunshine that its water content is dropped to a certain degree, then it is sent in hothouse.The method not only needs broad place, a large amount of manpower and materials to carry out maintenance and operation, and weather is required very high, needs sunshine and reach certain degree and air humidity lower than to a certain degree just carrying out.Although many restrictions, for the production equipment of existing biomass fuel, the method is caving-in bash purely.
