Abstract
The utility model relates to a horizontal coal-fired hot blast furnace with high efficiency, which is composed of various jackets and a system with multiple back strokes. A smoke and fire passage is composed of a flue (16), a smoke and fire box (4), the space outside tubes of a tube bundle component (9), a deflecting plate (17), an exhaust port (12), etc.; an air passage is composed of an air inlet (8), an inlet duct (13), a jacket (3), a jacket (7), air gathering boxes (18), (19), (20), (21), the space inside tubes of the tube bundle component (9), an air outlet (22), etc. The utility model makes the air entering the furnace thoroughly absorb the residual heat radiated from a hearth and the smoke and fire box, thereby, the thermal efficiency is enhanced.
Description
The utility model belongs to hot-air central heat supplying equipment.It is a kind of efficient horizontal coal-fired hot-blast stove.
Known horizontal coal-fired hot-blast stove has the horizontal reciprocal grate hot-blast stove of CN87207527U, and this stove inside and outside wall is an integral body, and no clamping device is penetrated heat to the width of cloth of burner hearth and whole smoke box and do not made full use of.Though this furnace thermal efficiency is higher, do not have utilization but still also have potentiality.
The purpose of this utility model provides a kind of efficient horizontal coal-fired hot-blast stove that chuck and many back haul system are arranged.
For achieving the above object, as shown in Figure 1 and Figure 2, by inwall (1), outer wall (2), pyrotechnics case (4), tube bank parts (9), burner hearth (10), reciprocal horizontal fire grate (11), exhaust opening (12), air inlet (8), air outlet (22), add coal bunker (15), fireworks channel, air duct etc. and form efficient horizontal coal-fired hot-blast stove.Wherein fireworks channel is formed many back haul system by flue (16), pyrotechnics case (4), the pipe external space of restraining parts (9), deflection plate (17), exhaust opening (12) etc.; Air duct is restrained the interior space of pipe of parts (9) by air inlet (8), air inlet duct (13), chuck (3), chuck (7), air collecting box (18), (19), (20), (21), and air outlet (22) etc. are formed another many back haul system.Pyrotechnics case (4) in the fireworks channel is made up of upper part, tube sheet (23), the base plate (5) of chuck inwall (1); Chuck in the air duct (3) by inwall (1) and outer wall (2) form, chuck (7) is made up of the base plate (5) of pyrotechnics case (4) and furnace roof cover plate (6).The direction of the fireworks channel of many backhauls and the air duct of many backhauls is orthogonal, makes air and high temperature pyrotechnics carry out sufficient heat exchange.
Advantage of the present utility model and good effect are: the chuck (3), the base plate (5) of pyrotechnics case (4) and the chuck (7) that furnace roof cover plate (6) is formed that have inwall (1) and outer wall (2) to form, make the air that enters in the stove can fully absorb the waste heat that burner hearth and the pyrotechnics case width of cloth shoot out, thereby improved the thermal efficiency.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 2
Fig. 4 is the structural representation of reciprocal horizontal fire grate.
Embodiment accompanying drawings of the present utility model is as follows:
As Fig. 1, Fig. 2, shown in Figure 3, by inwall (1), outer wall (2), pyrotechnics case (4), tube bank parts (9), burner hearth (10), reciprocal horizontal fire grate (11), exhaust opening (12), air inlet (8), air outlet (22), add coal bunker (15), fireworks channel, the efficient horizontal coal-fired hot-blast stove that air duct is formed, as can be seen from Figure 1, the high temperature pyrotechnics that is come out by burner hearth (10) is through flue (16), enter pyrotechnics case (4) vertically upward, because the effect of 4 deflection plates (17) is arranged in the pyrotechnics case, make pyrotechnics sweep away tube bank portion (9) five backhauls of flowing, carry out discharging (as shown in Figure 1) by exhaust opening (12) after the heat exchange of long period with air in the pipe.Enter the air in the stove, pass through air inlet (8) admission passage (13) by air blast, because stopping of dividing plate (25), air is passed through in the chuck (3) of cinclides in the both sides (26) (as shown in Figure 3) inflow inwall (1) and outer wall (2) composition, after entering chuck (3), air is divided into two-way (shown in arrow among Fig. 3), one the tunnel is subjected to the effect of dividing plate (27), make in the chuck (3) of its both sides below fire grate (11) by after flow forward, some wherein enters below the fire grate three air compartment coal supplies burnings by air compartment air inlet (36) (as shown in Figure 2) and uses, remainder is through passage (28) (as shown in Figure 3), under the stopping of dividing plate (29), make in its chuck that enters the burner hearth both sides (3), by flowing behind the forward direction, absorb the waste heat that the width of cloth shoots out in the burner hearth and improved air themperature, enter the chuck (7) interior (as shown in Figure 1) of pyrotechnics box plate (5) and burner hearth lamina tecti (6) composition then by the hole (30) on the inwall (1), make air heat absorption inflow again air collecting box (19).Another road of air, move up along dividing plate (31) (as shown in Figure 3) between inwall (1) and the outer wall (2) and the formed passage of rear wall (32) (33), enter the chuck (3) interior (as shown in Figure 2) of pyrotechnics box top and pyrotechnics case both sides, by after flow forward, absorb the waste heat that the pyrotechnics box top and the both sides width of cloth penetrate, its temperature is improved, enter in the air collecting box (19) (as shown in Figure 1) by the hole (34) (as shown in Figure 3) on the inwall (1) then, converge with last road air, together enter in first group of pipe in the tube bank parts (9), the high-temperature flue gas outer with pipe carries out the heat exchange first time, through the first time heat-exchanged air enter air collecting box (20) (as shown in Figure 1), because dividing plate (35) is isolated, air is turned back enter in second group of pipe, the high-temperature flue gas outer with pipe carries out the heat exchange second time, enter air collecting box (18) then, in the 3rd group of pipe, carry out heat exchange for the third time with high-temperature flue gas again, like this, air flows through three backhauls in the pyrotechnics case, air behind the acquisition high temperature is just discharged from exhaust outlet (22), delivers to the user by pipeline.
In addition, this hot-blast stove also is provided with air-flow plate (37) (as shown in Figure 2), asks grey hole (38), hand-hole (39), sees vent (40), ash output opening (41), scum hole (42).In addition, also be provided with fountain humidistat (44) (as shown in Figure 1).
