Description
Technical field
The invention belongs to industry air such as being applied to building materials, electric power, mine, metallurgy, chemical industry, plastic-coated, printing and dyeing, nonmetallic ore and concentrates technical field of heating, particularly relates to a kind of double-deck fuel gas hot-blast stove.
Background technology
Combustion type hot-blast stove adopts gaseous fuel directly burning in burner hearth exactly, the flue gas that fuel gas buring generates and excess air form hot blast, then directly contact and carry out heat drying or baking with material, be widely used in the every profession and trades such as building materials, electric power, mine, metallurgy, chemical industry, plastic-coated, printing and dyeing, nonmetallic ore.The consumption of this kind of method fuel is approximately than reduce half left and right with steam-type or other indirect heaters.Therefore,, in the situation that not affecting oven dry product quality, can use the high hot blast that purifies of direct-type completely.Fuel is gaseous fuel, as coal gas, natural gas, liquid gas.
The high-temperature combustion gas that fuel obtains after combustion reaction further contacts with outside air, directly enters hothouse or bakery after being mixed into a certain temperature, contact with the material that is dried, and heating, transpiring moisture, thus obtain dry products.Along with the development of plant-scale maximization and information control technology, specification and the accommodation of combustion type hot-blast stove significantly improve, and therefore the capacity usage ratio of combustion type hot-blast stove and automaticity are had higher requirement.
Combustion type hot-blast stove has various structures form and type, and common have monotubular Horizontal gas hot-blast stove, a Verticle gas hot-blast stove etc.Monotubular Horizontal gas hot-blast furnace equipment is heavy, and burner hearth integrates heat-resisting and is incubated, and thickness and weight are larger, and capacity usage ratio is low and investment is larger; Verticle gas hot-blast stove structure is tall and big, is difficult for arranging and safeguarding.
Summary of the invention
The invention provides a kind of double-deck fuel gas hot-blast stove for solving the technical problem existing in known technology, this bilayer fuel gas hot-blast stove simple in structure distinct, and dependable performance, with low cost, capacity usage ratio is high.
A kind of double-deck fuel gas hot-blast stove, comprise bearing, it is characterized in that: described bearing upper support has shell body, one end of shell body is provided with burner, burner bottom is provided with combustion air control valve, on the sidewall of shell body, near on the position of burner, be provided with cooling air control valve, in shell body, also by supporting guide plate, be supported with integrated internal layer burner hearth, the axial length of internal layer burner hearth be shell body axial length 60%～75%, supporting guide plate is divided into 3～4 groups, every group 6～8 uniform along internal layer hearth outer wall, and become 15～30 ° of angles to tilt with burner hearth axis, one end in the internal layer furnace outlet direction of shell body is provided with hot-blast outlet, at the internal layer burner hearth of shell body and the interval before hot-blast outlet, be also provided with temperature sensor and pressure sensor.
Advantage and good effect that the invention has are:
Because the invention adopts technique scheme, be provided with the passage of cooling air, cleverly burner hearth dispersed heat secondary recovery is utilized, cold air is also changed into hot-air, discharge together with after gas after burning in burner hearth mixes, be used for the dry and baking of material, thereby improved the utilization rate of energy.Double-deck chamber structure, with respect to individual layer burner hearth, has reduced burner hearth thickness, saves refractory material consumption, and investment is low with maintenance cost.

The specific embodiment
For further understanding innovation and creation content, the Characteristic of the invention, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As illustrated in fig. 1 and 2,
A kind of double-deck fuel gas hot-blast stove, comprise bearing 13, bearing upper support has shell body 3, one end of shell body is provided with burner 2, burner bottom is provided with combustion air control valve 11, on the sidewall of shell body, near on the position of burner, be provided with cooling air control valve 12, in shell body, also by supporting guide plate 5, be supported with internal layer burner hearth 4, supporting guide plate 5 is divided into 3～4 groups, every group 6～8 uniform along internal layer hearth outer wall, and become 15～30 ° of angles to tilt with burner hearth axis, the axial length of internal layer burner hearth be shell body axial length 60%～75%, one end connects burner 2, the other end is stretched to the mixed zone of combustion product gases and cooling air, one end in the internal layer furnace outlet direction of shell body is provided with hot-blast outlet 10, in internal layer burner hearth and the interval before hot-blast outlet of shell body, is also provided with temperature sensor 8 and pressure sensor 9.
On the shell body of section between internal layer furnace outlet and hot-blast outlet, be also provided with venting 7 and the access door 6 that is positioned at shell body side upward.
The operating principle of the invention is:
The utility model is mainly by burner 2, shell body 3, and internal layer burner hearth 4, bearing 13 and a set of automatic control cabinet form.Burner 2 is arranged on the middle part of body of heater front end face, and combustion gas sprays into burner hearth after mixing with combustion air, after being ignited, forms flame by igniter; Cooling air air inlet 12 is in body of heater front end side, cooling air is sent into the mezzanine space between internal layer burner hearth 4 and shell body 3 by outside blower fan or other power, the guiding of the supporting guide plate 5 that cooling-air tilts through many groups, cooling-air is evenly distributed rapidly in the outside of internal layer burner hearth, cover as soon as possible the large as far as possible outer surface of internal layer burner hearth, thereby after fully absorbing the heat that internal layer burner hearth side direction distributes, mezzanine space enters mixed zone, be mixed to form the required hot gas of user with the hot flue gas after burning, improved the utilization rate of the energy.Approaching hot-blast outlet end through temperature sensor 8 and pressure sensor 9, the temperature of hot blast and pressure data are gathered and are sent into automatic control cabinet 1 constantly; When hot blast temperature and pressure are during below or above setting value, regulating gas, combustion air and cooling air flow respectively after system-computed, the pressure that makes hot blast and temperature near setting value in certain interval maintenance stablize.
Although by reference to the accompanying drawings the preferred embodiment of the invention is described above; but the invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of the invention; not departing from the scope situation that the invention aim and claim protect, can also make a lot of forms, within these all belong to the protection domain of the invention.
