Abstract
The utility model discloses a heating device of a fruit and vegetable dryer. The heating device of the fruit and vegetable dryer comprises a furnace body, wherein two fire boxes are arranged at the upper end of the furnace body, the fire boxes are connected through a heat exchange pipe, one fire box is connected with a chimney, a negative pressure fan is arranged on the chimney, a secondary air duct is arranged on the furnace body, a secondary air inlet is formed in the secondary air duct, and the secondary air duct is connected into the furnace body through an air hole. According to the heating device of the fruit and vegetable dryer, the heat exchange capacity of the heating device is improved, secondary oxygen aeration is performed on the upper layer of the interior flame of a combustion furnace so that coal gas which is not fully combusted can be fully combusted, and black smoke and carbon monoxide emissions are reduced.
Description
Technical field
The utility model belongs to fruit and vegetable drying technical field, is specifically related to a kind of fruit and vegetable drying machine heating plant.
Background technology
Fruit and vegetable drying technology, for deep processing of farm products, improves the additional output value of agricultural product, has great importance, in the past drying agricultural product time, heat capacity is not enough, and combustion efficiency is bad, and waste of fuel is serious, during fume emission, not clean-burning combustion gas is excluded, and causes heat capacity not enough, and the dressing amount of drying in machine room increases, article drying time lengthens, and drying efficiency is low.
Utility model content
The utility model object is to improve the heat-exchange capacity of heating plant, on coal furnace internal flame upper strata, and secondary oxygenation, making to fail clean-burning coal gas fully burns, and reduces black smoke and carbon monoxide emission.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of fruit and vegetable drying machine heating plant, it comprises body of heater, described body of heater upper end arranges two fire-boxes, between described fire-box, by heat exchanger tube, connects, and one of them described fire-box is connected with chimney, on described chimney, negative-pressure air fan is set, on described body of heater, secondary air channel is set, on described secondary air channel, secondary air inlet is set, it is inner that described secondary air channel connects body of heater by wind hole.
Preferably, described secondary air channel is loop configuration.
Preferably, described secondary air channel is arranged at the position between body of heater and furnace roof.
Preferably, described secondary air inlet is arranged at the bottom of body of heater.
Preferably, described secondary air inlet and body of heater junction arrange wind hole.
Preferably, described inboard wall of furnace body arranges refractory brick.
Preferably, described fire-box inside arranges dividing plate.
The beneficial effects of the utility model are: adopt annular secondary air channel, secondary air inlet access positive blower, realize burner hearth bottom air-supply oxygen supply and a small amount of oxygen supply in burner hearth fuel top simultaneously, the fuel gas that fuel and fuel combustion process are produced, reach abundant burning, effectively reduce fuel consumption; Inboard wall of furnace body adopts highiy refractory brick, effectively increases the service life of body of heater, and furnace roof adopts weathering steel end socket, and upper attached fin effectively increases the fan thermal efficiency; By fire-box internal partition, flue gas S type is flowed, the S type of flue gas flows, and makes heat fully conversion in heat exchanger.The whole caloric value of body of heater, more than 150,000 kilocalories, effectively reducing fuel cost, makes full use of heat exchange, in integral device, uses, and effectively, good reaches the drying effect to required drying article.
