Abstract
The utility model discloses a cupola for a rock wool production line. The cupola comprises a cupola body, an oxygen supplying device, an oxygen detecting point, an on-line monitoring point, a gas flowmeter and a controller, wherein the oxygen supplying device is communicated with the cupola body, the oxygen detecting point and the on-line monitoring point are arranged in the cupola body, and the gas flowmeter and the controller are arranged on the oxygen supplying device. The controller is respectively in electric connection with the gas flowmeter, the oxygen detecting point and the on-line monitoring point. Certain amount of industrial pure oxygen is mixed into the cupola to serve as combustion-supporting gas by arranging the oxygen supplying device and the on-line monitoring point, so that fuels are sufficiently combusted, energy consuption can be reduced, and quality of rock wool fibers can further be improved. The on-line monitoring point of the content of gases of CO, SO3, NO2 and the like is arranged on the cupola body, ingoing gas composition of the cupola can be adjusted in time according to a monitoring result, and operation of a waste gas combustion system is controlled.
Description
Technical field
The utility model relates to a kind of furnace cupola of rock wool production line.
Background technology
Existing domestic cupola melting of producing for rock wool is to adopt the combustion-supporting smelting technology of hot-air, uses the hot-air obtained by furnace cupola tail gas and cold air heat exchange as combustion-supporting gas.Although this method is simple, has many shortcomings, as because oxygen content in air is low, cause the interior programming rate of stove slow; Fuel combustion is insufficient, causes in stove the gas content such as CO high, thus cause that the rock wool fibers of producing is short and thick, pliability and poor flexibility.Therefore, be difficult to produce the high-performance asbestos product by this technology.At present, along with the development of national economy and implementing of national energy-saving policy, the heat insulation demand with the high-performance asbestos product of building and industrial heat preservation is increasing, but the asbestos product on market is mostly low-end product, rock wool fibers is thick, crisp, and the goods weatherability is poor, and intensity is low, and heat insulation property is poor, can not meet instructions for use.Therefore, exploitation rock wool production new technology is significant.For solving the problem of current existence, we develop this furnace cupola oxygen enrichment melting process technology.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of furnace cupola of rock wool production line is provided, and utilizes furnace cupola to produce high-quality rock wool elongated, soft, good springiness under low energy consumption.
For achieving the above object, the technical solution of the utility model has been to provide a kind of furnace cupola of rock wool production line, comprise body of heater, the apparatus of oxygen supply be connected with described body of heater, be arranged at described body of heater interior oxygen detection point and on-line monitoring point, be arranged at gas flowmeter and controller on described apparatus of oxygen supply, described controller is electrically connected mutually with described gas flowmeter, described oxygen detection point, described on-line monitoring point respectively.
As preferably, on described body of heater, be provided with thermocouple.
As preferably, be provided with the gamma-rays level-sensing device on described body of heater.
As preferably, the bottom of described body of heater offers the melt-flow outlet.
As preferably, the 2%-5% that the intake of described oxygen is combustion air.
As preferably, described push pedal and described piston rod are fixedly connected by screw.
Advantage of the present utility model and beneficial effect are: by apparatus of oxygen supply and oxygen detection point are set at body of heater, a certain amount of industrial pure oxygen is sneaked in furnace cupola as combustion-supporting gas, make fuel combustion more abundant, not only can reduce energy consumption, also can improve the quality of rock wool fibers; The gas content on-line monitoring points such as CO, SO3, NO2 are set on body of heater, can adjust in time furnace cupola air inlet gas composition and control charge flow rate according to monitoring result, control the operation of burned waste gas system.
