Abstract
The invention belongs to the technical field of hot repair of glass furnaces and relates to a hot repair method of a port tongue arch of a coal-burning glass furnace. A burner of the coal-burning glass furnace mainly comprises an air regenerator, a gas regenerator and a port structure. A hot repair door is arranged on a regenerator backwall (8). When hot repair is started, an anti-explosion fire tube is ignited, an upper checker of the gas regenerator is dismantled, after the gas regenerator is sealed from the lower part, the hot repair door on the air regenerator is dismantled and an axial flow fan is opened, and upper and lower cooling water drains (10) are inserted from the upper hot repair door. When the temperature of the regenerator is lowered, an explosive port tongue arch (1) is dismantled and the new port tongue arch (1) is built. The invention adopts the method of changing the arch by manual cold repair, enters from the hot repair door on the port backwall and fundamentally changes the damaged tongue arch by reducing the temperature in the manual operation space, thus solving the problem that the materials finishing hot repair are gradually exfoliated and scoured in the prior art.
Description
Technical field
The invention belongs to glass furnace hot repair technical field, relate generally to a kind of hot repair method of coal-burning glass kiln port tongue arch.
Background technology
China has 31% field of world's glass production total amount, family surplus the glass enterprise size amounts to 300.Glass work had been obtained breakthrough development in the last few years, and at present China's floatation glass production line just has 186, and bigger development is all being arranged aspect scale and the technological progress, nearly 2 years the float glass line of building just have 20 surplus.Because factor and influences such as domestic demand is vigorous and the international market energy, raw material go up significantly, the heavy oil price presents obvious up-trend always, cause the glass cost of different fuel kind to differ increasing, the coal-fired and every loaded van glass of fuel oil price difference is about 30 yuan.Therefore, adjust fuel type, adopt the trend of the times of low-cost fuel.Lower-cost coal-burning glass furnace construction has been selected by the cold repair transformation by domestic a lot of glass producer.Little furnace structure is the burner of glass furnace, and the port tongue arch is the key position of port, and the port tongue arch is that coal gas kiln port is used for separating sky, coal gas horizontal channel.Its length, thickness and shape have very big influence to the mixing pre-burning of air gas to flame length, direction and the Temperature Distribution that sprays.At production period, the tongue arch is subjected to the influence of flame atmosphere and the erosion of high temperature gas flow, saturating condition of a fire condition appears easily, when the tongue arch is shortened by scaling loss gradually, not only influenced the junction position of air and coal gas, reinforcement is in the combustion rate of precombustion chamber, and space gas no show precombustion chamber is just burnt at tongue arch place by a part, has more accelerated the scaling loss of tongue arch; The tongue arch shortens and influences the length of flame and melt operation, and the ejiction opening temperature is too high, and flame raises up, and causes position masonries such as the flat arch of bocca, big arch arch quarrel beam very easily to burn out, and at this moment needs hot repair, the tongue arch that renews.
Enter from the port side wall in traditional in the past method, the way of employing water pipe arch tire is carried out hot repair and is changed arch.But because the prolongation in kiln age in recent years and the improvement of refractory material, method that the substitute is a kind of brand-new hot patching industrial furnace is a high temperature ceramic soldering technology, it can be from reinforcement damage position on the structure, do not need to support the arch tire, do not destroy the overall structure of body of heater, can directly material be welded on the arch body that peels off, its chemical stability and high high-temp stability are approaching with former brick.But because the tongue arch is under the erosion of special high temperature gas flow, change the erosion of washing away of heat exchange that fire brings and air-flow in the production, cause the material of vulcanizing progressively to be peeled off again and wash away, have a strong impact on the molten adhere of soldering body and parent, cause in conjunction with relaxing.
Summary of the invention
In order to solve above technical problem, the objective of the invention is to propose a kind of hot repair method of coal-burning glass kiln port tongue.
For finishing foregoing invention purpose the technical solution used in the present invention be:
A kind of hot repair method of coal-burning glass kiln port tongue arch, described coal-burning glass kiln burner mainly comprises air regenerator, gas regenerator and little furnace structure; And be connected between air regenerator, gas regenerator, the little furnace structure; Described air regenerator by regenerator top arch, regenerator after wall and space gas regenerator partition wall constitute; Described gas regenerator is made of space gas regenerator partition wall, gas regenerator wall; Described little furnace structure by port slope arch, back flat arch, side wall, port at the bottom of and the port tongue arch that is used for separating sky, coal gas horizontal channel constitute; Described port tongue arch is positioned at the top of gas regenerator, and the top of port tongue arch is equal with the top of space gas regenerator partition wall; Lower plane at the bottom of the described port is equal with the top of gas regenerator wall; Wall is provided with the hot repair door after the described regenerator; When hot repair begins, light explosion-proof fire tube, remove the top checker of gas regenerator, after obturaging from below in the gas regenerator, remove hot repair door on the air regenerator, and open axial flow blower, insert cooling water water row up and down from last hot repair door; After the regenerator temperature lowers, can between air hot repair door and space gas regenerator partition wall, cost three snakelike water bags, both sides are blocked with steel plate; Operating walk way is laid with thermal insulation board, spreads to the tongue arch, will obturage all around with brick and heat-preservation cotton; Fried port tongue arch is split in dismounting, props up after cleaning out and puts tongue arch tire, builds new port tongue arch by laying bricks or stones, spreads the thick zirconium pounding rice material of 20mm in the above, tight tongue arch arch quarrel jackscrew; Take down the brick on the water row then, heat-preservation cotton remove the water bag, and progressively the machine of turning off the blast is blown cooling air, is heated up in the space, removes water row up and down, envelope hot repair door.
The hot repair method of a kind of coal-burning glass kiln port tongue arch that the present invention proposes, adopt artificial cold repair to change the arch way, enter from port back wall hot repair door, adopt and reduce the manually-operated space temperature, the tongue arch that damages is carried out the replacing of essence, solved the material of vulcanizing in the prior art and progressively peeled off the problem that washes away.
