Background technology
Along with China development of economic construction needs, to industries such as chemical building material food in process of production the heat exchange process of granular material requirements at the higher level have been proposed, much do not have the granular material of temperature requirement to cool originally.For example: cement is as the building material product that exists with the granular material form, and the cement temperature that goes out mill is generally more than 100 ℃, and easily institute's gypsum dehydration influences product quality, finally influences the concrete construction quality of architectural engineering.In present cement production process process both domestic and external owing to do not have suitable cement cool technology and equipment, strengthen in only taking to grind and ventilate, water spray, the general type of cooling of the outer trickle of mill, but DeGrain, and there are a lot of drawbacks and accident potential, so far still there is not a kind of feasible method and apparatus to solve this difficult problem, though a kind of vertical barrel cement cooler that occurs before and after 2000, because its water consumption is excessive, more than the 100T/h, corrosion and wearing and tearing to equipment are big, complex structure, and equipment volume is big, the maintenance cost height, labour intensity is big, and cost performance is low and be difficult to be accepted by vast cement production enterprise.Industry application pneumatic conveying methods such as chemical industry, pharmacy, food, grain, mineral products for example again, use a kind of equipment that is called as source of the gas cooler and straight-line oscillation fluid bed dryer, allow the air stream of motion that granular materials such as the high magnesium carbonate of temperature, calcium carbonate are evenly cooled off, but these two kinds of methods has certain cooling effectiveness, but the plant maintenance amount is big, production scale is little, unsuitable large-scale production.
Summary of the invention
A kind of solid-liquid heat exchanger provided by the invention, be with recirculated cooling water as the cooling medium that liquid form exists, make as the granular material of solid-state form when of the present invention, finish indirect heat exchanging process, make the temperature of granular material obtain descending.
The technical scheme of technical solution problem of the present invention is: a kind of solid-liquid heat exchanger, form by turn back chamber and rapping apparatus of housing, heat exchange chamber, cooling water inlet, coolant outlet, tubulose heat exchanger, cooling-water duct, granular material inlet, granular material outlet, cooling water.
Wherein, heat exchange chamber is positioned at the housing middle part, the cooling water chamber of turning back is positioned at the two ends of housing heat exchange chamber, cooling water inlet and coolant outlet are positioned at the outer side of housing, the tubulose heat exchanger is arranged in the heat exchange chamber, and cooling-water duct is positioned at the tubulose heat exchanger, and the granular material inlet is located at the top of housing, the granular material outlet is located at lower part of frame, and rapping apparatus is located on the outer wall of housing.
Above-mentioned a kind of solid-liquid heat exchanger that is used for granular material, the end of each tubulose heat exchanger connects in cooling water is turned back the chamber mutually, constitute the flow of cooling water loop, when cooling water flows, can constantly low temperature evenly be delivered to whole tubulose heat exchanger in cooling-water duct.
Above-mentioned a kind of solid-liquid heat exchanger that is used for granular material, the tubulose heat exchanger profile that is positioned at heat exchange chamber is designed to the solid of rule, be not only in order to obtain bigger heat exchange area, help granular material simultaneously and after carrying out heat exchange, fall rapidly, avoid in heat exchange chamber, producing accumulation phenomena with tubulose heat exchanger surface.
Above-mentioned a kind of solid-liquid heat exchanger that is used for granular material, be positioned at a plurality of tubulose heat exchangers of heat exchange chamber and be orderly staggered so that granular material can fully contact with tubulose heat exchanger surface by heat exchange chamber the time.
Above-mentioned a kind of solid-liquid heat exchanger that is used for granular material is provided with several cooling waters chamber of turning back at the heat exchange chamber two ends, each cooling water turn back the chamber all with several tubulose heat exchangers in cooling-water duct be connected perforation.
Above-mentioned a kind of solid-liquid heat exchanger that is used for granular material, in order to reduce the wearing and tearing of granular material to the tubulose heat exchanger, the tubulose heat exchanger is to adopt high-abrasive material to make.
Above-mentioned a kind of solid-liquid heat exchanger that is used for granular material, looking production technology needs to take single solid-liquid heat exchanger mode to use, and also can take a plurality of solid-liquid heat exchanger in series modes to use.
Above-mentioned a kind of solid-liquid heat exchanger that is used to be located on the housing outer wall, the rapping apparatus that is located on the housing outer wall can prevent granular material in the heat exchange chamber inner accumulated, to keep the isostatic movement of granular material in heat exchange chamber.
Among the present invention, granular material is passing through heat exchange chamber, with carry out heat exchange in the contacting of the tubulose heat exchanger that is in low-temperature condition, be to utilize focusing on certainly in the free-falling process of granular material to carry out, the heat exchanging process of granular material and tubulose heat exchanger does not need to apply any power.
The beneficial effect of technical solution of the present invention is simple in structure, heat exchanger effectiveness height, operating cost are low, no drive disk assembly, safeguard simple, do not need to apply any power, have energy-conservation and cost performance advantages of higher, can in the industry production processes such as chemical building material food granular material cool off, especially comparatively obvious to the cooling effect of cement.
