Above-mentioned traditional kiln, has the following disadvantages: (1), because waste gas is with higher heat, high-temp waste gas is so directly drained, and obviously causes heat waste, affects the thermal efficiency, loss heat energy; Further, kiln in use, needs specified heat, and the direct discharge of high-temp waste gas, the heat energy that meeting loss is more, for making up dispersed heat, can consume the more energy, this will inevitably cause more toxic emission, contaminated environment, and, increase production cost.
Summary of the invention
The object of the invention is to overcome the deficiency existing for above-mentioned prior art, and provide a kind of simple and reasonable for structure, waste gas circulation can be made to utilize, to improve the thermal efficiency, to reduce energy consumption and the kiln of energy-conserving and environment-protective.
The object of the present invention is achieved like this:
There is the energy saving kiln that waste gas circulation utilizes, comprise the section of burning till and smoke evacuation section, the section of burning till is provided with air inlet and waste gas outlet, it is characterized in that, between the described section of burning till and smoke evacuation section, waste gas air-introduced machine is set, waste gas air-introduced machine is provided with air intake vent and air outlet, described air intake vent is communicated with the waste gas outlet of the section of burning till, and its air outlet is connected by the air inlet of exhaust gas recycling tube with the section of burning till; This kind of energy saving kiln having waste gas circulation to utilize, by arranging waste gas air-introduced machine between the section of burning till and smoke evacuation section, utilize the part high-temp waste gas that the section of burning till is discharged by waste gas air-introduced machine, again dropped in the section of burning till by exhaust gas recycling tube, its heat is recycled, improve the thermal efficiency, reduce energy consumption, realize the effect of energy-conserving and environment-protective.
Object of the present invention can also adopt following technical measures to solve:
As better scheme, the level height of described waste gas air-introduced machine air intake vent higher than air outlet, the suction of this top, bottom discharge design, be conducive to high-temp waste gas by again drop into the section of burning till time, meet heat rising principle, the effect that waste gas heat is exchanged is better.
As scheme more specifically, between the described section of burning till and smoke evacuation section, changeover portion is set, air-introduced machine is arranged on the bottom of changeover portion, its air intake vent to extend on changeover portion and near the waste gas outlet of the section of burning till, like this, be conducive to the high-temp waste gas that waste gas air-introduced machine extracts the section of burning till discharge, to improve the cyclic utilization rate of waste gas.
In order to reduce noise further, be provided with mounting groove bottom described changeover portion, waste gas air-introduced machine is arranged in mounting groove, and the lateral wall of mounting groove also has additional puigging.
High-temp waste gas is dropped into the section of burning till again, can by the distance of a section longer, for avoiding heat loss, the tube wall of described exhaust gas recycling tube comprises four layer materials and forms, by innermost layer, to outermost layer, they are that poly-light ball high-alumina brick internal layer, corrosion resistant plate, heat-preservation cotton and aluminium sheet are outer respectively, and are insulating brick masonry in kiln.
The invention has the beneficial effects as follows:
(1) the present invention has the energy saving kiln that waste gas circulation utilizes, by arranging waste gas air-introduced machine between the section of burning till and smoke evacuation section, utilize the part high-temp waste gas that the section of burning till is discharged by waste gas air-introduced machine, again dropped in the section of burning till by exhaust gas recycling tube, its heat is recycled, improve the thermal efficiency, reduce energy consumption, realize the effect of energy-conserving and environment-protective.
(2) further, it is also by having additional puigging at mounting groove lateral wall, prevent the heat of high-temp waste gas from being fallen apart; And, high-temp waste gas is dropped into the section of burning till again, can by the distance of a section longer, for avoiding heat loss, the tube wall of described exhaust gas recycling tube comprises four layer materials and forms, and by innermost layer, to outermost layer, they are that poly-light ball high-alumina brick internal layer, corrosion resistant plate, heat-preservation cotton and aluminium sheet are outer respectively, and are insulating brick masonry in kiln, like this, what can further improve waste-gas heat recycles effect.
