Abstract
The utility model discloses a flue gas channel of a heater for a dense tobacco flue-curing house. A flue gas pipeline of the heater is arranged at the top of a heating furnace; the heating furnace is communicated with the inside of a heat exchanger, wherein the lower end of the flue gas pipeline is welded (or connected) to the top of the heating furnace; the upper end of the flue gas pipeline is connected with a pipeline of a heat exchanger through a flange; and heat-radiating fins are welded on the outer side wall on the right side of the flue gas pipeline. The plurality of heat-radiating fins are stacked on the outer side wall of the flue gas pipeline of the heater for the dense tobacco flue-curing house so as to improve the heat exchange efficiency of the heat exchanger and cold air from a cold air inlet, improve the curing quality of hot air on tobacco leaves and reduce energy consumption.
Description
Technical field
The utility model relates to the tobacco leaf process equipment, and particularly tobacco flue-curing house specifically is a kind of exhaust gases passes of dense tobacco flue-curing house heater.
Background technology
Baking is that of cured tobacco production must link.The tobacco flue-curing equipment of China mostly is traditional earth roasting house greatly, and structure is very simple and crude, and firing equipment is that sun-dried mud brick or brick and tile are built by laying bricks or stones, and by the gravity-flow ventilation heat exchange, the thermal efficiency is low, and waste of fuel is serious; Some bulk curing barns of Jian Zaoing in recent years, there are many defectives in the structural design of heat exchanger and configuration, mostly are workshop-based and make by hand, random big, stove and heat exchanger volume are huge and not compact, and hot flue gas flow path is short, flow velocity is fast, and heat release and heat exchange are insufficient, and heat utilization efficiency is low.Therefore, be necessary prior art is improved, improve heat utilization ratio, reduce the flue-cured tobacco energy consumption.
Summary of the invention
The purpose of this utility model is to provide a kind of exhaust gases passes of dense tobacco flue-curing house heater, and it is unreasonable that the exhaust gases passes of described this dense tobacco flue-curing house heater will solve in the prior art heater design of cured tobacco curing house, causes the technical problem of energy waste.
The purpose of this utility model is achieved through the following technical solutions: this dense tobacco flue-curing house heater exhaust gases passes is located at the heating furnace furnace roof, heating furnace is connected with heat exchanger inside, wherein, this exhaust gases passes lower end is welded on the heating furnace furnace roof, the upper end is connected with the fire-box of heat exchanger by flange, is welded with fin on the lateral wall on exhaust gases passes right side.
Be welded with 6 fin on the lateral wall on exhaust gases passes right side, these 6 heat radiations are along the equidistant setting of exhaust gases passes lateral surface.
Fin is the fin of high 30mm, long 150mm, thick 4mm.
The utility model is compared with prior art, and its effect is actively with tangible.The exhaust gases passes lateral wall of dense tobacco flue-curing house heater of the present utility model is provided with a plurality of fin, improves heater and heat exchange efficiency from the cold wind of cold wind air inlet, cuts down the consumption of energy; The exhaust gases passes upper end is connected with the pipeline of heat exchanger with bolt by flange simultaneously, strengthens to connect seal.
Description of drawings
Fig. 1 is the front view of the utility model exhaust gases passes.
Fig. 2 is the vertical view of the utility model exhaust gases passes.
Fig. 3 is the A-A cutaway view of the utility model exhaust gases passes Fig. 1.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, indoor heating furnace and the heat exchanger of being provided with of the hot blast of this dense tobacco flue-curing house heater, this exhaust gases passes 3 is located on the heating furnace furnace roof, heating furnace is connected with heat exchanger inside, these exhaust gases passes 3 lower ends are welded on the heating furnace furnace roof, the upper end is connected with the fire-box of heat exchanger with bolt by flange, be welded with 6 fin 4 on the lateral wall on exhaust gases passes 3 right sides, these 6 heat radiations are along the equidistant setting of exhaust gases passes lateral surface, and fin 4 is fin that the acid resisting steel of high 30mm, long 150mm, thick 4mm is made.
The effect of fin is the heat transfer that helps heat exchanger and extraneous air, and its quantity is the amount doesn't matter, and minimum can be one, but owing to be subjected to the restriction of exhaust gases passes size, also can not be too many, present embodiment employing 6 is comparatively suitable.
Claims (3)
