Abstract

The invention discloses a production system and a production method of micro fiber glass wool. The production system comprises a melting kiln, a fuel gas source, a first air blower, a wiredrawing leaking plate, a wool blowing device, a second air blower, a wool collecting device and a controller. The production method comprises the following steps: (1) performing heating melting; (2) performing wiredrawing; and (3) performing wool blowing. The production system and the production method have the beneficial effects of being simple in structure and easy to achieve, in addition, an automatic control function is achieved, the stability of the beating degree of the glass wool can be ensured, and furthermore, quality stability of the produced glass wool can be ensured; stability of pressure of ejected flame air flow can be ensured, furthermore, the shot content in the product, namely the glass wool, is reduced, and the quality of the glass wool can be improved; the use amount of a fuel gas can be reduced, electric energy consumption can be reduced, and the production cost can be lowered.

Description

Technical field: [0001] The invention relates to the technical field of glass wool production, in particular to a production system of microfiber glass wool and a production method thereof. Background technique: [0002] Glass wool is an inorganic fiber. Because of its good shape, small bulk density, low thermal conductivity, good heat insulation, good sound absorption, corrosion resistance and good chemical properties, it is widely used in oil pipelines and natural pipelines. air field. At present, the main production method of microfiber glass wool is the flame blowing method. [0003] At present, the flame blowing method melts the glass frit into a glass solution through a kiln, and then blows it through a flame to form glass fibers. This method is suitable for producing glass wool with an average diameter of less than 2.0um and is widely used; The above-mentioned flame injection method has the following problems: 1. At present, the temperature of the molten glass gob i...

Problems solved by technology

[0003] At present, the flame blowing method melts the glass frit into a glass solution through a kiln, and then blows it through a flame to form glass fibers. This method is suitable for producing glass wool with an average diameter of less than 2.0um and is widely used; The above-mentioned flame injection method has the following problems: 1. At present, the temperature of the molten glass gob in the kiln is detected by a thermocouple instrument, and the detected data will be displayed on the instrument, and the changes of the data are observed manually at all times, and the fuel gas flow rate is measured. Adjustment with the flow rate of the auxiliary gas will easily lead to adjustment lag, which will lead to unstable temperature in the kiln, resulting in unstable drawing, poor stability of glass wool's beating degree, and thus unstable quality of glass wool; 2. Flame When spraying and drawing, manual adjustment is performed by manually observing the data of the fuel gas flow rate and the auxiliary gas flow rate displayed on the flow meter. The flame air flow is unstable, which in turn makes the slag content in the product glass wool high, which affects the quality of the glass wool; 3. Since the fuel gas flow rate of the heating furnace and flame injection is manually adjusted, there will be a problem of adjustment lag. Then it will lead to a large amount of fuel gas consumption, resulting in waste and increased production costs; 4. At present, the blown glass wool needs to be sent to the collection device under the action of the induced draft fan for collection, which consumes a lot of power and increases production. cost
