In the above-mentioned technical solutions, of the invention simple in construction, air is delivered to air preheater by the first air blower, Carry out heating up after heat exchange by the higher waste gas of air preheater and temperature, the hot-air after preheating is entered by the first inlet air plenum Enter in burner hearth, material is entered in body of heater by charging gear, the second air blower blasts air from the second inlet plenum, air will Material is dispelled so that material arrangement is uniform, and after material is burnt, waste gas is arranged by the exhaust opening of combustion chamber through exhaust gases passes Go out, hot flue gas carries out that heat exchange is laggard to cross deduster dust removal by filtration with air preheater, and the air after dedusting is in flow direction feed dress Put it is interior material is dried, therefore formed circulation wind path so that energy regenerating reuse, burn it is more abundant, more save Environmental protection.
As the preferred of above-mentioned technical proposal, second inlet plenum is located at the top of the mobile grate.
As the preferred of above-mentioned technical proposal, the rear end of the mobile grate is provided with the first vault, the second vault and the Three vaults, the height of first vault is higher than the second vault, and the height of second vault is higher than the 3rd vault.
As the preferred of above-mentioned technical proposal, the distance between the bottom of the 3rd vault and the top of mobile grate are In 0-10 centimeters.
As the preferred of above-mentioned technical proposal, formed between first vault and second vault and the 3rd vault Stepped vault.Dust certain in flue gas can be blocked, effectively by the high-temperature flue gas stream and mistake of fire grate rear end superjacent air space Measure air and be oriented to combustion centre so that burning is more concentrated.
As the preferred of above-mentioned technical proposal, the body of heater, the first vault, the second vault and the 3rd vault are by refractory brick It is built into.
As the preferred of above-mentioned technical proposal, polylith flow apron is provided with the deduster, the flow apron will be removed Dirt device is divided into multiple expansion chambers.The expansion chamber that waste gas is flowed through gradually increases, and because flow velocity declines, dust gravitational settling is collected, water conservancy diversion Baffle plate extends holdup time of the waste gas in expansion chamber, strengthens dust removal effect.
As the preferred of above-mentioned technical proposal, the flow apron dislocation is disposed with three pieces.
The invention has the advantages that:
1st, contact drying is carried out simultaneously using the exhaust fumes produced in biomass boiler production process as load using heat exchange There is provided energy utilization rate for gas convection drying.
2nd, fume afterheat first carries out heat exchange, preheated air, then drying object by cascade utilization by air preheater and air Material, has the advantages that high-efficient energy-saving environment friendly.
3rd, biomass material drying, combustion integrative, realize high water content biomass material and directly use, reduce and build If land used, cost of investment is reduced.
4th, the deduster that the system is used, reaches dust removing effects, eliminates the conventional dust removal system such as bag-type dust, equipment is more Simply, maintenance operation cost is relatively low.
