Biomass thermal conversion heat supply drying unit
The utility model belongs to biomass energy, renewable energy utilization apparatus field, relates to a kind of biomass thermal conversion heat supply drying unit.
In the prior art, biomass thermal conversion heat supply drying unit, gasification furnace adopts downdraft (being that fire burns from the top down) more, but great majority adopt split type for gasification and two stages of burning, be connected to the water filter between the two, and this device is because of technological requirement, need seat to go into underground about 1.5 meters, burning (definitely say and be second-time burning) is after the stage, hot blast is sent into hothouse again after heat exchanger is joined the cold wind temperature adjustment, its defective is the hot blast temperature shakiness, the hothouse temperature distributing disproportionation, dries quantity can not get ensureing, especially in water filter and the front and back connecting line thereof, tar accumulates in a large number, adhesion, stop up, need often to clean, and carbon quarrel amount is big in the gasification section, this not only greatly reduces the biomass energy thermal conversion efficiency, and a large amount of carbon monoxide in the gas and flue gas bring when second-time burning is put out a fire very big hidden danger, particularly combustion chamber in for rear portion system and hothouse, and carbon monoxide can be scurried into hothouse in a large number, and when rekindling, the accident of easily blasting.In operation, all independent start-stop of the big blower fan that air distribution is used when little blower fan of drying for burning and heat exchange is opened little blower fan point stove, burning earlier, open big blower fan temperature adjustment again, in case big blower fan is stopped transport for some reason, little blower fan still runs well, at this moment, fire has the danger of directly scurrying into hothouse, so operation also bothers.Single with regard to gasification furnace, also have two sections coupling types (seeing Chinese patent 90209560.9) epimere to be drying, pyrolysis, gasification, reduction, hypomere is second-time burning, though overcome above-mentioned split type defective, but its reducing zone is positioned at the epimere feed bin fully, this stove is based on producing coal gas, so there are a large amount of carbon residues to produce, the biomass energy conversion ratio is low, with regard to the certain total efficient heat of external output, equipment is huge, cost height, grate and first and second blowing device inconvenient maintenance simultaneously.
The purpose of this utility model is to provide a kind of biomass thermal conversion heat supply drying unit, can overcome the defective of above-mentioned prior art, employing downdraft gasification---the gasification furnace that burning is integrated, so that living beings provide maximum efficient heat is purpose, make reducing zone be positioned at the combustion chamber fully, biomass energy thermal conversion rate height, almost do not have carbon residue, and improve the flow process of supplying gas, electronic temperature controller and safe bell are set, reach the efficiency of combustion height, it is clean to send hot blast, and temperature stabilization is easily transferred, and guarantees system safety operation, easy to operate again, the good maintenance.
Concrete scheme is as follows: comprise feed bin 1, combustion chamber 2, the two dismoutability connects as one, little blower fan 3, and its wind outlet divides a two-way to connect wind inlet and secondary wind inlet respectively; Heat exchanger 5 and big blower fan 6, its wind outlet enters in the interlayer of heat exchanger 5 through the cold wind import 5-3 of heat exchanger 5 tangent line, also have relevant control valve and connecting line, it is characterized in that: also have buffer 4, dismoutability is connected between combustion chamber 2 and the heat exchanger 5, the heat outlet 2-8 that is combustion chamber 2 is connected with the gas feed 4-1 dismoutability of buffer 4, and its gas vent 4-2 is connected with the gas feed 5-1 dismoutability of heat exchanger 5; The gas outlet tube 5-2 straight cutting of heat exchanger 5 is gone into hothouse; In combustion chamber 2, have opposite opened grate 2-6 and be positioned at its top, support is on the boss of refractory lining 2-5, one time wind wind apparatus 2-1 is positioned at grate 2-6 top, secondary wind wind apparatus 2-3 is positioned at grate 2-6 bottom, and as a complete unit, reducing zone is positioned at combustion chamber 2 fully; Feed bin 1 has hydrolock feed bin lid 1-1 (being bell), and its water sealed tank is made up of with weldering water sealed tank outer wall 1-2 thereon the part bulkhead suitable for reading of feed bin 1; Electronic temperature controller 7, its temperature control point t 2Drawn by hothouse, the simultaneously little blower fan 3 of chain connection, big blower fan 6 are controlled it simultaneously and are opened and stop.
Usefulness of the present utility model is: gas is integrated for two sections with burning, and reducing zone is positioned at the combustion chamber fully, the efficiency of combustion height, biomass energy thermal conversion rate height, no tar is clear to be gone out, also few residual fixed carbon quarrel, cancellation water filter, set up buffer 4, have the dedusting back-fire relief function of holding concurrently, and shortened flow process, thermostat 7 and hydrolock feed bin lid 1-1 is set, can not only make the hot blast of sending clean, temperature stabilization is easily transferred, and can guarantee the total system safe operation, same fashionable dress, tear open, fortune is convenient, the good maintenance, easy to operate, cost is low, applied widely.
