2Fully reaction makes internal moisture be difficult for discharging simultaneously, has affected the drying efficiency of pearlite heat-insulation plate, has reduced simultaneously its intensity and hydrophobic effect, causes the decline of pearlite heat-insulation plate quality.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide that a kind of waste gas reclaims fully, saves energy and the energy, reduce production costs and improved the pearlite heat-insulation plate tunnel drying oven of product quality.
The technical scheme that its technical problem that solves the utility model adopts is:
described pearlite heat-insulation plate tunnel drying oven, comprise body of heater, the heating clamber that is connected with body of heater, the body of heater top arranges waste gas and reclaims mouth, waste gas reclaims mouth and is connected with the outside reclaim line of body of heater, gas-gas heat exchanger is set on reclaim line, gas-gas heat exchanger inside arranges coil pipe, coil pipe one end connects reclaim line, the coil pipe other end arranges exhaust vent, gas-gas heat exchanger top sets out gas port, the gas outlet is connected with heating clamber by pipeline, the gas-gas heat exchanger bottom arranges air inlet, the body of heater front portion arranges insulated wall, insulated wall is perpendicular to ground, insulated wall is divided into two sections with body of heater, leading portion is the low temperature drying section, back segment is the hyperthermia drying section, the low temperature drying section is set up air blast.
Described insulated wall is positioned at apart from fire door 9-10 rice.
Described air blast is positioned at apart from fire door 6-8 rice, and the air blast of setting up is used for increasing Cryogenic air and CO
2Content.
Described body of heater length is 34.6-35.2 rice.
During work, the warming plate of extrusion forming is pushed in body of heater, power-on begins heating.During normal operation, hyperthermia drying section temperature is the 160-200 degree, and the low temperature drying section is the 80-100 degree.The air blast of setting up and insulated wall make furnace temperature and atmosphere obtain effectively controlling, and are conducive to improve intensity and the hydrophobicity performance of pearlite insulation panel products.
Contain a large amount of steam in waste gas due to the dry run generation, set up gas-gas heat exchanger and make the heat of waste gas be fully utilized, the waste gas after heat exchange enters in atmosphere, can not cause any pollution to air.Directly enter heating clamber with the part air of waste gas heat exchange, improved the temperature that enters the heating clamber air, saved the energy.
The beneficial effect that the utility model has is:
The utility model is simple in structure, easy to manufacture, easy to maintenance; In use, the waste gas that dry run is produced reclaims fully, has saved electric energy and the energy, has reduced production cost, has improved intensity and the hydrophobicity performance of pearlite insulation panel products, has promoted the quality of pearlite heat-insulation plate.
