Abstract
The invention discloses a heat source recycling method for producing rock wools. The method comprises the following steps of putting raw materials and fuel into a cupola furnace; combusting the raw materials and the fuel in the cupola furnace; through a combustion chamber with a U-shaped pipe, sufficiently combusting waste gas combusted in the cupola furnace, so as to obtain a recycled heat source; heating combustion supporting air in the U-shaped pipe until the temperature of the combustion supporting air reaches 400-600 DEG C; introducing the recycled heat source after heating the combustion supporting air into a curing furnace by a high temperature induced draft fan; enabling the temperature in the curing furnace to reach 190-250 DEG C through a plurality of hot circulating fans communicated with the curing furnace; curing and molding a wool plate; leading the combustion supporting air into the cupola furnace to support combustion; and pumping and discharging the waste gas generated by the curing furnace into desulfurization equipment for treatment by using a waste gas fan. According to the invention, the emission of harmful gases in the cupola furnace can be reduced and the harmful gases are recycled.
Description
Technical field
The present invention relates to a kind of thermal source recycling method for rock wool production, be mainly used in the waste gas recycling of cupola furnace.
Background technology
At present, the now domestic old-fashioned cupola furnace that mostly is for rock wool production, intensification in the stove is slower, fuel combustion is insufficient, and the obnoxious flavour content such as carbon monoxide in the stove are higher, and curing oven institute heat requirement is burnt to provide by diesel oil, coal, coke, Sweet natural gas equal energy source, energy consumption is relatively high, for this reason, we have researched and developed this thermal source recycling method for rock wool production, to guarantee to reduce noxious gas emission, energy-saving and cost-reducing.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of discharging that can reduce the cupola furnace obnoxious flavour is provided, and to the thermal source recycling method that rock wool produces that is used for of this obnoxious flavour recycling.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of thermal source recycling method for rock wool production, and the step of the method is as follows: raw material and fuel are dropped into the cupola furnace internal combustion; The waste gas of cupola furnace internal combustion is fully burnt by the Burning Room that is furnished with U-shaped pipe, and the thermal source that is reused is given the heating of the combustion air in the U-shaped pipe, until the temperature of combustion air reaches 400 ℃ ~ 600 ℃; To introduce curing oven by high temperature air inducing blower fan to the recycling thermal source after the combustion air heating, and make by the some thermal circulation fans that are communicated with curing oven that temperature reaches 190 ℃ ~ 250 ℃ in the curing oven, make cotton plate curing molding, be passed in the cupola furnace combustion air combustion-supporting to cupola furnace; The waste gas that curing oven produces detaches by exhaust gas fan and drains into the sweetener processing.
After having adopted technique scheme, the inventive method is introduced Burning Room with waste gas, first with the secondary combustion such as carbon monoxide, sulfurous gas, hydrogen sulfide in the waste gas, waste gas after the burning provides heat to curing oven again, has reduced the airborne release pollution, simultaneously to cupola furnace provide through the heating combustion air, in addition, curing oven does not need to provide in addition the heat energy, can save coke consumption approximately 20%, reaches the effect of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the device connection diagram of thermal source recycling method of producing for rock wool of the present invention.
Embodiment
Content of the present invention is easier to be expressly understood in order to make, and the below is according to specific embodiment and by reference to the accompanying drawings, and the present invention is further detailed explanation,
As shown in Figure 1, a kind of thermal source recycling method for rock wool production, the step of the method is as follows: raw material and fuel are dropped into cupola furnace 3 internal combustion; The waste gas of cupola furnace 3 internal combustion is fully burnt by the Burning Room 4 that is furnished with U-shaped pipe 5, and the thermal source that is reused is given the heating of the combustion air in the U-shaped pipe 5, until the temperature of combustion air reaches 400 ℃ ~ 600 ℃; To introduce curing oven 9 by high temperature air inducing blower fan 6 to the recycling thermal source after the combustion air heating, and make curing oven 9 interior temperature reach 190 ℃ ~ 250 ℃ by the some thermal circulation fans 7 that are communicated with curing oven 9, make cotton plate curing molding, be passed in the cupola furnace 3 combustion air combustion-supporting to cupola furnace 3; The waste gas that curing oven 9 produces detaches by exhaust gas fan 10 and drains into the sweetener processing.
In order to improve the fusing amount, and make the time that cupola furnace can non-stop run can reach 30-50 days, melt temperature can reach 1500-1700 ℃, guarantee stream burst abundant fibroblast, improve productive rate, lay one deck alumina firebrick, two-layer coke powder in cupola well 1 bottom of cupola furnace, one deck brick fuel, total thickness is 300mm, and lays on this basis a circle brick fuel 500*400*200mm, cupola well 1 residue internal diameter 1.4m, guarantee enough melt spaces, make the furnace bottom insulation, can operate for a long time, the shaft interior periphery is built the thick refractory brick insulation of upper 220mm protection, 2 coolings of outer wall water distribution chuck, melting band burner hearth internal diameter is 1.6m.
Burning Room 4 can be built into refractory brick, and inner with 15 groups of U-shaped pipes 5 connections of stainless steel, guarantees that the waste gas that freezing air is discharged by cupola furnace 3 in the pipe fully heats.
When producing, guaranteeing per hour has the combustion air of 4500-5000m3 to blast cupola furnace 3, to guarantee that furnace charge fully burns, strictly controls simultaneously charging time, frequency, to guarantee adjusting air force according to road conditions at any time, reach optimum melting state with the Frequency Converter Control roots blower.
The inventive method is introduced Burning Room 4 with waste gas, first with the secondary combustion such as carbon monoxide, sulfurous gas, hydrogen sulfide in the waste gas, waste gas after the burning provides heat for curing oven 9 again, reduced the airborne release pollution, combustion air through heating is provided for simultaneously cupola furnace 3, in addition, curing oven 9 does not need to provide in addition the heat energy, can save coke consumption approximately 20%, reach the effect of energy-conserving and environment-protective.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
