Integral type heat supply purification apparatus

The utility model relates to an integral type heat supply and purification device, wherein an air inlet, an air outlet, a waste gas inlet, and a waste gas outlet are arranged on an outer shell of the heat supply and purification device; a burning and purifying furnace is arranged between the air inlet and the air outlet; the waste gas inlet and the waste gas outlet are connected with the burning and purifying furnace. A high temperature filter is arranged at a place near the air outlet; one end of the outer shell is provided with a circulation fan. The fan, the filter, the burning and purifying furnace and a heat exchanger are all assembled and arranged in the outer shell so as to form a compact and ordered whole. The utility model forms an energy saving product which integrates circulation, heating, filtration and environmental protection into a whole. The utility model uses an inner circulating air system, which ensures the quality of workpieces and the drying temperature. Compared with the known structure, the utility model reduces pipe connection, which reduces the hidden dangers of airflow resistance and gas leakage and improves the heat efficiency of the equipment. Meanwhile, the utility model reduces producing and maintaining cost and reduces land occupying area of the equipment.
