The utility model discloses having saved the resource, stabilized steam system, having improved the utilization ratio of the steam energy, the work load, the energy consumption that have alleviateed the staff are little, rate of equipment utilization is high.
Description
Technical field
The utility model relates to a kind of chemical plant installations, is specifically related to the conduction oil device in the production of a kind of phthalic anhydride.
Background technology
The heating of traditional conduction oil device conduction oil directly utilizes oil pump to carry out hot melt from being transported to switch condenser again after deep fat tank sucking-off conduction oil is heated by hot oil, moment oil temperature lifting causes steam fluctuation to strengthen upon reflow affects device stable operation, it is produce the device that steam is also use steam that phthalic anhydride is produced, if vapour system instability makes the increasing of technological operation difficulty adjust not in time makes the flow of rectifying column heating steam reduce directly affect seed output and quality, and switch condenser expects contaminated environment reduction yield because hot melt not exclusively causes to run.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the conduction oil device in providing a kind of phthalic anhydride to produce, and stablizes vapour system, reduces energy consumption, improves the quality of products and yield.
The utility model solves the technical scheme that its technical problem adopts:
Conduction oil device in phthalic anhydride production described in the utility model, comprise deep fat tank and cold oil tank, accumulation of heat oil tank, deep fat tank, Long-distance Control valve, hot oil pump, the first valve, the first thermometer are connected successively with PA Plant, accumulation of heat oil tank, accumulation of heat oil pump, hot oil, the second valve are connected successively with the second thermometer, second thermometer, accumulation of heat oil tank are connected successively with the 3rd valve, 3rd valve is connected with Long-distance Control valve, hot oil pump respectively, and cold oil tank, cold oil pump, cooling oil cooler are connected according to this with PA Plant.
Described deep fat tank is provided with injector, is used for the oil in deep fat tank is entered in accumulation of heat oil tank.
Operation principle and process:
Conduction oil in accumulation of heat oil tank is carried by accumulation of heat oil pump, through the heating of hot oil by the second thermometer control temperature, accumulation of heat oil tank is returned again through the second valve, deep fat in deep fat in deep fat tank and accumulation of heat oil tank is respectively by regulating the aperture of Long-distance Control valve and the 3rd valve used in combination by the first thermometer control temperature, enter PA Plant through hot oil pump and the first valve to use, deep fat returns deep fat tank after using, and the oil of deep fat tank sucks back accumulation of heat oil tank by vacuum.Conduction oil in cold oil tank is carried by cold oil pump, through the cooling of cooling oil cooler, is supplied to after PA Plant cooling uses and returns cold oil tank.
The beneficial effect that the utility model has is: the utilization rate saving resource, stabilize vapour system, improve steam energy, and the workload, the energy consumption that alleviate employee are little, utilization rate of equipment and installations is high.
