Therefore need improve existing drying unit, make the oven dry air-flow can utilize whole combustion of natural gas heats, with energy savings; Can quick adjustment dry gas flow temperature simultaneously, help improving the product dries quantity.
The utility model content
In view of this, the purpose of this utility model provides a kind of heater of direct heating, drying operation air-flow, thermal current behind the combustion of natural gas is directly mixed with oven dry operation air-flow, the heat of combustion of natural gas can all be absorbed by oven dry operation air-flow, to improve heat utilization ratio, energy savings; Can quick adjustment dry the operation gas flow temperature simultaneously, help guaranteeing the product dries quantity.
The heater of the direct heating, drying operation of the utility model air-flow, comprise that the air-flow heating clamber, combustor and the air inlet that are provided with recyclegas import and recyclegas outlet export the frequency conversion fan that is connected with recyclegas, described air-flow heating clamber inner chamber is provided with the burner block of band fuel gas inlet and gas outlet, described burner block fuel gas inlet is communicated with the combustor gas outlet, and the burner block gas outlet is communicated with air-flow heating clamber inner chamber.
Further, described burner block gas outlet is provided with crown shape decompression plate;
Further, also comprise electric control gear, described electric control gear comprises the temperature sensor and the controller that is used to receive the temperature sensor detection signal and sends control signal to combustor that is used to detect oven dry operation gas flow temperature;
Further, described air-flow heating clamber locular wall is provided with manhole;
Further, the import of described air-flow heating clamber recyclegas is provided with the FAI Fresh Air Intake lock;
Further, described air-flow heating clamber wall thickness is 30-35cm.
The beneficial effects of the utility model: the heater of the direct heating, drying operation of the utility model air-flow, thermal current directly mixed with the oven dry operation air-flow that returns from the circulating current import after natural gas fully burnt in burner block, directly to the heating of oven dry operation air-flow, the heat of combustion of natural gas can all be absorbed by oven dry operation air-flow, the heat utilization ratio height, energy savings; The crown shape decompression plate that is arranged on the burner block gas outlet can avoid burner block to produce high negative pressure, prevents that combustor is flame-out; The controller of electric control gear can be regulated flame size automatically according to the temperature information control combustor that temperature sensor transmits, make the oven dry gas flow temperature remain on setting range, simultaneously because of being direct heating, drying air-flow, therefore it is fast to dry operation gas flow temperature governing speed, favourable raising product dries quantity.
