The beneficial effects of the utility model are, solved the defective that exists in the background technology, the utility model is installed simple and convenient, can realize the collection of Cupola flue dust and the cooling of flue gas, realized simultaneously the utilization of Cupola fume afterheat, effect with energy-saving and emission-reduction has reduced greenhouse effects and atmospheric heat and polluted, and is significant to preventing global warming.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Among the figure: 1. safety valve; 2. cooling medium; 3. buffer board; 4. housing; 4-1. cooling medium inner chamber; 4-2. cooling medium inlet; 4-3. cooling medium outlet; 4-4. gas approach; 4-5. exhanst gas outlet; 5. ash port; 6. cooling tube group.
The specific embodiment
With preferred embodiment the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of furnace cupola spark capturing device as shown in Figure 1 comprises housing 4 and cooling tube group 6; Described housing 4 comprises cooling medium inner chamber 4-1, be separately positioned on described housing 4 bottoms and top cooling medium inlet 4-2 and cooling medium outlet 4-3, be separately positioned on gas approach 4-4 and the exhanst gas outlet 4-5 of described housing 4 left surfaces and right flank; Described cooling tube group 6 is the top and the bottom of the described cooling medium inner chamber 4-1 of UNICOM respectively.
Further, described furnace cupola spark capturing device also comprises buffer board 3, and described buffer board 3 is fixed on the inside near the housing 4 of described gas approach 4-4.The effect of buffer board 3 is to make furnace gas process of stream once in this device, so as fully and cooling medium 2 carry out heat exchange.
Preferably, described furnace cupola spark capturing device also comprises the safety valve 1 that is installed in described housing 4 tops.The effect of safety valve 1 is for the outlet pipe that prevents cooling medium outlet 4-3 blocks, and internal pressure is too high and set off an explosion.
Preferably, described furnace cupola spark capturing device also comprises the ash port 5 that is installed in described housing 4 bottoms.Ash port 5 can be got rid of big dust particle by being connected with cement output tank.
Preferably, the left surface of the described housing 4 of described furnace cupola spark capturing device arranges a pair of gas approach 4-4.By being set, a pair of gas approach 4-4 can realize that two furnace cupolas share a cover furnace cupola spark capturing device, have improved the service efficiency of furnace cupola spark capturing device when having reduced cost.
After adopting technique scheme, the furnace cupola flue gas is by behind this device inwall, and temperature can obviously descend and the inwall steel plate produces distortion owing to the cooling of cooling medium is difficult; Cooling medium is that cooling medium is capable of producing hot water for worker's bathing owing to directly not contacting with flue gas if adopt running water, plays heat exchanger.The utility model is owing to adopting water jacket structure, and ash-collecting port is arranged at the bottom, and cooling medium is water.
