Abstract
The utility model relates to a water backflow prevention exhaust device of a calcination furnace. The water backflow prevention exhaust device consists of a waste gas recycling pipe, an air inlet pipe, an air outlet pipe, a water return pipe and an overflow pipe, wherein the air inlet pipe is welded on the top of the calcination furnace, the air outlet pipe is connected with the upper end of the air inlet pipe, the water return pipe is welded on the bottom of the recycling pipe and communicated with the waste gas recycling pipe, the overflow pipe is arranged on the lower part of the water return pipe, the height of the air outlet pipe is greater than that of the water return pipe, and the lower end of the overflow pipe is connected with the calcination furnace. The water backflow prevention exhaust device has the advantages that the overflow pipe is connected to the lower part of the water return pipe, the water return pipe is connected with the waste gas recycling pipe, if cooling water is in the waste gas recycling pipe, the cooling water can directly flow back to the water return pipe and is finally discharged from the overflow pipe, so that the water is enabled not to be stored in the water return pipe. The height of the air outlet pipe is greater than that of the water return pipe, and the cooling water can only flow into the water return pipe and cannot enter the furnace through the air outlet pipe, so that the corrosion and damage of internal parts of the furnace caused by the cooling water containing the corrosive substances can be prevented.
Description
Technical field
The utility model relates to a kind of waterproof backflow vent device of calcination stove.
Background technology
Calcination stove is a kind of roaster conventional in metallurgy, chemical field, be mainly used in the decomposition of compound, the decomposition of most compounds all can be accompanied by the discharge of waste gas and water vapour, but the waste gas that current domestic calcination fire grate goes out is all directly by pipeline, to enter reclaimer, at calcination stove, break down after blowing out, or again during blow-on, in blast pipe, just having a large amount of water vapour condensations enters in stove, relevant device in body of heater and stove is caused to damage, reduce the service life of calcination stove, increase production cost.
Summary of the invention
The utility model is for overcoming the above problems, proposed a kind ofly in blow-on or blowing out, can prevent that cooling water is back in body of heater, prevent the relevant device in body of heater and stove to cause damage, extend the service life of calcination stove, reduce production costs, and simple in structure, be convenient to the waterproof backflow vent device of the calcination stove made.
Technical solution of the present utility model is:
A kind of waterproof backflow vent device of calcination stove, by exhaust gas recycling tube 2, the air inlet pipe 3 that is welded on calciner 1 top, the escape pipe 5 being connected with air inlet pipe 3 upper ends, be welded on the return pipe 4 that recovery tube 2 bottoms are communicated with exhaust gas recycling tube 2, the overflow pipe 6 that is arranged on return pipe 4 bottoms forms, the height of described escape pipe 5 is higher than return pipe 4, and overflow pipe 6 lower ends are connected with calciner 1.
Described escape pipe 5 is positioned at return pipe 4, and air inlet pipe 3 upper ends, escape pipe 5 lower ends and return pipe 4 lower ends are connected by flange 7.
The utility model has the advantages that: overflow pipe is connected to return pipe bottom, return pipe is connected with exhaust gas recycling tube, if there is cooling water in exhaust gas recycling tube, can flow directly into return pipe, then from overflow pipe, discharges, and has ensured that return pipe does not have ponding.Because the height of escape pipe is higher than return pipe, cooling water can only flow to return pipe like this, and cannot flow in stove by escape pipe, has prevented that the cooling water that contains corrosive substance is to the corrosion of furnace interior part and damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
In figure: 1. calcination stove, 2. exhaust gas recycling tube, 3. air inlet pipe, 4. return pipe, 5. escape pipe, 6. overflow pipe, 7. flange.
The specific embodiment
As shown in the figure, the waterproof backflow vent device of this calcination stove, by exhaust gas recycling tube 2, the air inlet pipe 3 that is welded on calciner 1 top, the escape pipe 5 being connected with air inlet pipe 3 upper ends, be welded on the return pipe 4 that recovery tube 2 bottoms are communicated with exhaust gas recycling tube 2, the overflow pipe 6 that is arranged on return pipe 4 bottoms forms, the height of described escape pipe 5 is higher than return pipe 4, and overflow pipe 6 lower ends are connected with calciner 1.
Described escape pipe 5 is positioned at return pipe 4, and described air inlet pipe 3 upper ends, return pipe 4 lower ends and escape pipe 5 lower ends are connected by flange 7.
During work, the decomposition gas that contains a large amount of water vapours in calcination stove 1 directly enters exhaust gas recycling tube 2 by air inlet pipe 3, escape pipe 5, and the finally outlet by exhaust gas recycling tube 2 enters waste gas recovery equipment.If blow-on or calcination stove are while breaking down blowing out; the a large amount of water vapours that contain in waste gas will be cooling in waste gas return pipe 2; become the cooling water with chemical substance; because the aspect ratio return pipe of escape pipe 5 is high by 4; so cooling water can enter in return pipe 4; overflow pipe 6 by return pipe 4 bottoms flows to wastewater disposal basin through calcination stove 1, thereby reaches the object of protection calcination stove 1.
Claims (2)
1. the waterproof backflow vent device of a calcination stove, it is characterized in that: by exhaust gas recycling tube, the air inlet pipe that is welded on calciner top, the escape pipe being connected with air inlet pipe upper end, be welded on the return pipe that recovery tube bottom is communicated with exhaust gas recycling tube, the overflow pipe that is arranged on return pipe bottom forms, the height of described escape pipe is higher than return pipe, and overflow pipe lower end is connected with calciner.
2. the waterproof backflow vent device of calcination stove according to claim 1, is characterized in that: described escape pipe is positioned at return pipe, and described air inlet pipe upper end, escape pipe lower end and return pipe lower end are connected by flange.
