Abstract
The utility model relates to a vertical type fire tube coal burning hot blast stove, and is to eliminate the problem of prior art that ash deposits in prior fire tubes easily and the thermal efficiency of prior art is low. Regarding the utility model, fire tubes communicated with a flue is provided inside a hearth; an air passage is provided around the fire tubes; an air inlet is provided on the upper part of the stove body; an air outlet is provided on the lower part of the stove body. The fire tubes are vertical fire tubes normal to the flue. In the utility model, prior inclined fire tubes are changed into vertical fire tubes, so ash does not deposit in the fire tubes of the utility model; in addition, number of layers of the fire tubes is increased, the heat exchange area is increased so that the thermal efficiency of the hot blast stove is significantly improved.
Description
Technical field
The utility model relates to air heater with heat-generating device, specifically, be a kind of be medium with the air, anhydrous, coal-burning heating equipment.
Background technology
At present, utilize air-flow to realize the hot-blast stove of thermal power transfer, kind is more, and structural design is various.CN2826283Y disclosed " fire-tube type coal-fired hot-blast stove ", its combustion chamber is communicated with flue by some fire tubes, flue is arranged on the both sides of body of heater, fire tube is from being divided into several unit pipes groups down, be arranged on the middle part of body of heater, the pipe end place of adjacent tubes group is communicated with flue, and the periphery of fire tube is an air duct, the body of heater top is provided with air inlet, and the body of heater below is provided with air outlet.The shortcoming of this hot-blast stove is: 1, since fire tube for being obliquely installed, so the inner easy dust stratification of fire tube; 2, because the unit pipes group is two-layer, and heat exchange area is less, fully heat exchange, a large amount of heat energy enter atmosphere, and heat exchanger effectiveness is lower.
Summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of dust stratification that can solve fire tube is provided, and can make the vertical fire tube coal-fired hot-blast stove of the thermal efficiency enhancing of hot-blast stove again.
The utility model is achieved in that a kind of vertical fire tube coal-fired hot-blast stove, comprise: the fire tube that is communicated with flue is set in body of heater, burner hearth, fire door, flue, the exhanst gas outlet, burner hearth, and the periphery of fire tube is an air duct, the body of heater top is provided with air inlet, and the body of heater below is provided with air outlet.Described fire tube is the vertical fire tube perpendicular to flue.
Described fire tube is divided into 5 unit pipes groups with dividing plate with it, is provided with air hole between each unit pipes group.
Described unit pipes group is made up of 2～3 layers of fire tube.
The utility model compared with prior art has the following advantages: 1, because fire tube changes vertical fire tube into by original inclined fire tube, so be difficult for dust stratification in the fire tube; 2, owing to increased the number of plies of fire tube, increased heat exchange area, so that the thermal efficiency of hot-blast stove strengthen greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
Below in conjunction with accompanying drawing,, the utility model is further described by embodiment.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of vertical fire tube coal-fired hot-blast stove, comprise: body of heater 1, burner hearth 2, fire door 3, flue 4, exhanst gas outlet 11, the fire tube 5 that is communicated with flue 4 is set in the burner hearth 2, the periphery of fire tube 5 is air ducts 6, body of heater 1 top is provided with air inlet 7, and body of heater 1 below is provided with air outlet 8, and its described fire tube 5 is the vertical fire tube perpendicular to flue.
Described fire tube 5 usefulness dividing plates 9 are divided into 5 unit pipes groups with it, are provided with air hole 10 between each unit pipes group.
Described unit pipes group is made up of 2～3 layers of fire tube.
Among the figure: single arrow is represented the flow of flue gas direction, and double-head arrow is represented air-flow direction, and 5-1 represents that flue gas advances, and 5-2 represents that flue gas goes out.
Identical with general hot-blast stove, also be provided with air blast.
