The specific embodiment:
The energy-saving water-saving device of " cold-hot-cold " gluing technique, be at other each one of hot water circuit jar (80～90 ℃ of water temperatures), warm water circulating tank (40～45 ℃ of water temperatures) and the cold water circulatory pool that is provided with of multi-daylight press, respectively by pipeline and valve, form independently circulating system device of three in hot water, warm water and cold water.Hot water circuit jar, warm water circulating tank and pipeline thereof need seal and carry out insulation and handle, and the cold water circulatory pool is an open dug reservoir.The method of " cold-hot-cold " gluing technique energy-saving and water-saving is the initial stage at the pressurize cooling stage, mid-term and later stage, utilize the hot water cyclesystem device respectively, warm water circulating system device and cold water circulating system device, in order successively to about 145 ℃, about 100 ℃ and each layer heating platen and the slab thereof of multi-daylight press under about 60 ℃ carry out the cooling of three steps, it is cooled to about 100 ℃ in proper order, about 60 ℃ and about 30 ℃, the high-temperature water that it is produced in proper order then, middle warm water and water at low temperature are carried out the recycling of three steps, thereby reach the purpose (Fig. 1) of using water wisely and heat energy.
The cooling of first step and recycling be initial stage at the pressurize cooling stage, at this moment, valve on the breakdown hot water circuit jar pipeline, the hot water of hot water circuit jar is cooled off each layer heating platen and the slab thereof with the multi-daylight press about 145 ℃ by pipe-line system, it is cooled to about 100 ℃, the high-temperature water that is produced is back to the hot water circuit jar again.The water temperature that is back to the hot water circuit jar this moment is higher than the temperature of jar interior water.Meanwhile, the hot water of hot water circuit jar enters the radiator of a plurality of dry kilns by pipe-line system, utilizes the heat energy of hot water that the workpiece in the dry kiln is carried out drying, and then is back to the hot water circuit jar.The water temperature that enters the hot water circuit jar this moment is lower than the temperature of jar interior water.By two cyclic processes, the dynamic equilibrium that has kept the hot water circuit jar water yield on the one hand, be back to the hot water circuit jar by the high-temperature water that heating platen produced simultaneously, compensated the water temperature reduction that is back to the hot water circuit jar from the dry kiln radiator again, thus the dynamic equilibrium that has kept hot water circuit jar water temperature substantially.If when the water temperature of hot water circuit jar is lower than 85 ℃, can supply with small amount of steam, make its water temperature remain at 85～90 ℃ of states by steam boiler.When the temperature of each layer heating platen of multi-daylight press and slab thereof drops to 100 ℃ of left and right sides, close the water inlet and the flowing water Valve that lead to multi-daylight press on the hot water circuit jar pipeline, and lead to the water inlet and the flowing water Valve of multi-daylight press on the while breakdown warm water circulating tank pipeline.
The cooling of second step and recycling be mid-term at the pressurize cooling stage, the warm water of warm water circulating tank is cooled off by each layer heating platen and the slab thereof of pipe-line system to about 100 ℃ multi-daylight press, it is cooled to about 60 ℃ again, and the middle warm water that is produced is back to the warm water circulating tank again.The water temperature that is back to the warm water circulating tank this moment is higher than the temperature of jar interior water.Meanwhile, the warm water circulating tank is transported to the softened water tank of steam boiler by pipe-line system with its a part of warm water, pumps into steam boiler again, by improving the feed temperature of steam boiler, to save the firing rate of boiler; And another part warm water is transported to worker's publilc baths makes bath water.The water yield of warm water circulating tank and water temperature be to cool off with the cold water of cold water circulatory pool each layer heating platen and the slab thereof to about 60 ℃ multi-daylight press, and the part in the water at low temperature that is produced is transported to the warm water circulatory pool and keeps its dynamic equilibrium.When the temperature of each layer hot press of multi-daylight press and slab thereof drops to 60 ℃ of left and right sides, close the water inlet and the flowing water Valve that lead to multi-daylight press on the warm water circulating tank pipeline, and lead to the water inlet and the flowing water Valve of multi-daylight press on the while breakdown cold water circulatory pool pipeline.
The cooling of the 3rd step and recycling be in the later stage of pressurize cooling stage, with the cold water of cold water circulatory pool, cool off by each layer heating platen and the slab thereof of pipe-line system to about 60 ℃ multilayer hot water machine, it is cooled to about 30 ℃ at last.The water at low temperature that is produced preferentially is injected into the warm water circulating tank, be transported to the water yield of steam boiler softened water tank and worker's publilc baths with additional warm water circulating tank, can reduce simultaneously the water temperature of warm water circulating tank, make its water temperature stability at 40～45 ℃, thereby keep the water yield of warm water circulating tank and the dynamic equilibrium of water temperature.Unnecessary water at low temperature all is back to the cold water circulatory pool and uses, to replenish the water yield of cold water circulatory pool, carry out again recycling, simultaneously by the open-air water temperature that reduces the cold water circulatory pool of cooling off naturally.When the temperature of each layer heating platen of multi-daylight press and slab thereof drops to 30 ℃ of left and right sides, close the water inlet and the flowing water Valve that lead to multi-daylight press on the cold water circulatory pool pipeline.
The present invention is the pressurize cooling stage at " cold-hot-cold " gluing technique, the temperature of each layer heating platen of multi-daylight press and slab thereof is being cooled to about 30 ℃ about by 145 ℃, when guaranteeing its slab bonding quality requirement, cooling by first, second and the 3rd step reaches and economizes on water and purpose of energy saving with recycling.
