Abstract
The utility model discloses a natural gas shuttle kiln which belongs to the field of industrial kilns and comprises a kiln body and a flue positioned at the bottom of the kiln body, and is characterized in that two side walls of the kiln body are respectively provided with more than one gas inlet, and the gas inlets on the same side wall are arranged in a high-low staggered way. For the gas shuttle kiln, gas is adopted as material, the quality of the gas supplied in a unified way is constant, and the flow rate of all gas inlets of the kiln body is easy to control, so that the gas of all gas inlets is uniform, and temperature balance in the kiln is facilitated; as the gas inlets are arranged in a high-low staggered way and are uniformly distributed, temperature at the upper part and the lower part in the kiln body is further promoted to be consistent, thus ensuring the quality of burnt finished products to be stable, and improving the yield of the finished product.
Description
Technical field
The utility model belongs to the Industrial Stoves field, is specifically related to a kind of natural gas shuttle kiln.
Background technology
At present, because the coal resources rich of China, related furnace construction is fairly simple, and the early investment cost is lower, so in industrial processes is produced, select the coal kiln mostly for use, is in charge of the burning application of kiln by veteran senior engineer; But in actual production, the influence of many-sided factors such as Coal Quality, combustion position makes that the interior temperature of kiln is unbalanced, has a strong impact on the qualification rate of finished product.On the other hand, the burning degree of coal is difficult to control, has noxious materials such as volume of smoke and sulfur dioxide in the discharged flue gas of burning back, does not reach standard limit of smog release.
Owing to cause the factor of the problems referred to above too many, this coal kiln is difficult to form automation control, causes the problems referred to above to be difficult to solve always, becomes the bottleneck that kiln uses and develops.
Summary of the invention
The utility model technical problem to be solved provides a kind of natural gas shuttle kiln, can make kiln temperature balanced.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of natural gas shuttle kiln is provided; Comprise kiln body and flue; Flue is positioned at the bottom of kiln body, it is characterized in that: offer more than one fuel gas inlet on the two side of kiln body respectively, be height with the fuel gas inlet of sidewall and be crisscross arranged.
The inwall of kiln body is provided with heat-insulation layer.
The top of kiln body is curved, and the height of arched top is half the greater than kiln body width.
The beneficial effect of the utility model is:
1, use combustion gas instead and make raw material, the combustion gas quality of unified supply is constant, and the flow velocity of each fuel gas inlet of kiln body is prone to control, can make the burning of each fuel gas inlet unified, is beneficial to and realizes that kiln temperature is balanced; Fuel gas inlet just is crisscross arranged, and fuel gas inlet is evenly distributed, and further impels the temperature at the interior position up and down of kiln body consistent, thereby has guaranteed to fire the steady quality of finished product, has improved product qualified rate.
2, the heat-insulation layer of kiln body inwall setting can reduce scattering and disappearing of the interior heat of kiln, avoids energy waste.
3, the arched top of kiln body is beneficial to the circulate of air-flow in the kiln body, realizes that further kiln temperature is unified, balanced.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A structural representation of Fig. 1;
Among the figure: 1, kiln body, 2, flue, 3, fuel gas inlet, 4, heat-insulation layer.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
In the utility model, the length direction of kiln body 1 is defined as vertically, the pairing kiln body side surface in end that stands on the kiln body with human body is a sidewall, accordingly, the width of kiln body 1 is defined as laterally, short transverse is vertical.
Like Fig. 1, shown in 2, the cross section of the natural gas shuttle kiln that is provided is rectangle, and kiln body 1 is built into by refractory brick, and the bottom of kiln body 1 is provided with flue 2, and the inwall of kiln body 1 is provided with heat-insulation layer 4, effectively reduces scattering and disappearing of heat in the kiln body 1, plays a part energy-conservation.Offer four fuel gas inlet 3 on the two side respectively; Be the staggered vertical arrangement setting of height with four fuel gas inlet 3 on the sidewall; Wherein two fuel gas inlet 3 of two side are positioned on the same vertical section of kiln body 1; And be one high and one low setting, realize the even laying of fuel gas inlet 3, guarantee that kiln temperature is balanced.The top of kiln body 1 is curved, and the height of arched top is half the greater than kiln body 1 width, is beneficial to the circulate of airstream in kiln, impels kiln temperature further constant, same.
In use,, the kiln car of treating burned product pushes in the kiln body 1, with 1 sealing of kiln body being housed; Each fuel gas inlet 3 feeding natural gas takes fire and fires then; Natural gas flow velocity through controlling each fuel gas inlet 3 is consistent, makes the temperature in the kiln body 1 same, evenly; To guarantee the constant mass of finished product, improve the qualification rate of finished product.
It is to be noted; Above-mentioned embodiment only is the utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets the utility model operation principle, any be equal to or similar replacement all falls in the protection domain of the utility model.
Claims (3)
