Description
Technical field
The present invention relates to a kind of heat-exchange device, particularly hot oil steam generating apparatus.
Background technology
All need to use steam in general production plant, the generation of its steam is to make water become steam with coal-burning boiler, oil burning boiler or electrical heating.And in industries such as rubber, shoemaking, weaving, clothes, food, printing and dyeing, chemical industry, also have a lot of operations to need to add thermal material as 350 ℃ circulation with high temperature, also need steam to use simultaneously in other operation.Also may need hot water to use.Like this, just be provided with three and overlap independently heater, and need three cover operations, attendant, need procuring equipment, and the equipment operation management expense is relatively large.It is also bigger that three complete equipments take factory's area.The relative efficiency of heating surface can be lower, and energy resource consumption is bigger.
Content of the present invention
The purpose of this invention is to provide hot oil steam generating apparatus, utilize it to heat and produce steam or hot water, can save equipment investment, equipment operation management expense, factory building area occupied, main is the energy energy savings, improves the efficiency of heating surface, improves heating quality.
The objective of the invention is to realize by following technical scheme.Hot oil steam generating apparatus comprises tank body, deep fat pipe, and the deep fat pipe is arranged in tank body, and two ends of deep fat pipe link to each other with oil return pipe with oil inlet pipe respectively, are provided with water inlet pipe and steam pipe on tank body.Described deep fat pipe is that coil pipe or described deep fat pipe are some straight tubes.It is characterized in that: be connected with drum in described steam pipe exit.Also comprise secondary tank body and secondary coil, secondary coil is contained in the secondary tank body, and two ends of secondary coil stretch out in outside the secondary tank body, and the entrance point of secondary coil links to each other with oil return pipe, and the port of export links to each other with the suction inlet of oil pump through valve.The deep fat of hot oil steam generating apparatus of the present invention is from the hot oil furnace supporting with it, and the structure of hot oil furnace can be the structure of fire tube boiler, and the fuel that this hot oil furnace uses can be industrial refuse or other fuel.The supporting use of the present invention and hot oil furnace recycles after the deep fat heating, and deep fat is sent to apparatus of the present invention from hot oil furnace, after heat exchange generates steam, returns hot oil furnace, sends after the heating again.After perhaps deep fat is delivered to another heating station use earlier, deliver to apparatus of the present invention heat exchange again and produce steam.Generate the deep fat sent behind the steam also again heat exchange produce hot water.The benefit of doing like this is: investment and the equipment operation management that can save steam boiler, hot-water boiler and corollary equipment thereof take, reduce this hold facility plant area, but main is energy savings, because the steam boiler combustion thermal efficiency is lower, and the combustion thermal efficiency of hot oil furnace is higher, the thermal efficiency of a hot oil furnace heating will be higher than the thermal efficiency of two equipment (be hot oil furnace, steam boiler uses separately).In addition, the oil of hot oil furnace is to recycle, and the heat loss that is in operation is less.Because the specific heat of oil is about 1/2nd of water, same heat joins in oil with volume, the water, the oil temperature rise must rise much higher than water temperature, therefore with same heat oily temperature is at high temperature worked, this can make the heat exchange efficiency height of heat exchanger, work quality is improved, the applicant is with two identical heat exchangers, fill the water and the oil of 0.78 cubic metre of same volume respectively, burner with 3.5 ten thousand kilocalories heats respectively, in the time of 45 minutes, oily temperature has reached 102 ℃, and water just reaches 100 ℃ in heating in the time of 95 minutes.Therefore, can be half as large with the heat exchanger of deep fat heat exchange than the area of the heat exchanger of boiler, its consumptive material is few, volume is little, power is big.Its efficiency of heating surface improves.
In sum, the present invention utilizes hot oil furnace heating deep fat through the heat exchanger heat exchange, produce steam, or the deep fat waste heat that utilizes hot oil furnace comes heat exchange to produce steam, can save equipment investment and equipment operation management expense, save the factory building area occupied, save operating energy resource consumption, significantly improve the efficiency of heating surface.The present invention is applicable to the enterprise that uses steam, is specially adapted to enterprises such as rubber, shoemaking, weaving, clothes, food, printing and dyeing, chemical industry and uses.
