Description

The energy-conservation nonstorage calorifier of oil storage tank

Technical field

The utility model relates to the heat energy apparatus field, especially the heater of oil storage tank.

Background technology

Because crude oil or furol viscosity are big, mobile poor at normal temperatures, during oil plant turnover oil storage tank, oil plant need be heated, reduce the viscosity of oil plant, raising is mobile, so for the oil storage tank of crude oil or the oil storage tank of heavy oil heater must be housed.The saturated vapor that the high steam that the thermal source of heater generally all adopts high pressure steam boiler to produce produces after the heat exchanger heat exchange feeds the heating tube in the oil storage tank heater, and oil storage is heated.Heating tube in the present heater is a U type structure, vertically is loaded in the oil storage tank, and the oil plant in whole jar is heated, no matter how much take oil mass, all oily temperature is heated to 60 ℃, so heating process is very uneconomical.As for a 500m ³Oil storage tank, oil temperature to be brought up to 60 ℃ from 30 ℃ in summer, generally need heat 12-24 hour; Oil temperature to be brought up to 60 ℃ from 10 ℃ in the winter time, generally need heat 24-48 hour, need to consume a large amount of heat energy.Because the distribution of heating tube can not be distributed in a jar interior each several part equably, so higher near the oil plant temperature of heating tube, lower away from the oil plant temperature of heating tube, the temperature of oil exit pipe oil-in is lower, has had a strong impact on the flow regime of oil extraction.Because what adopt at present is the free convection mode of heating, heat transfer coefficient is low, and is higher from the condensate temperature that drain port is discharged, and often is attended by a large amount of steam discharges, increased the consumption of steam; Simultaneously, because too high, and be trapped in its surface when long, very easily produce analyte in the oil plant temperature on heating tube surface, and in the heating surface coking, and then influence the heat transmission, influence heat transfer efficiency; Owing to repeatedly oil plant is heated, produced a large amount of tiny analytes, the oil plant quality is descended, increase the post-processed cost.This shows that the heating situation of oil storage tank must obtain changing, and could improve the thermal efficiency, reduces the consumption of steam, reduces cost, and improves the quality of oil plant.

The utility model content

The purpose of this utility model is for providing a kind of thermal efficiency height, and steam consumption quantity is low, and the oil storage cost is low, the energy-conservation nonstorage calorifier of oil storage tank simple in structure.

The technical scheme that realizes above-mentioned purpose is as follows:

The energy-conservation nonstorage calorifier of oil storage tank, steam heater is housed in oil storage tank, the steam heater level is loaded on the oil storage tank bottom, the steam heater head gos deep into being installed on the support in the oil storage tank, the steam heater other end stretches out from tank body, be connected with the steam heater afterbody by flange, the reentrant type steam-heating pipe is housed in steam heater, the steam inlet and the drain port of steam-heating pipe are housed at steam heater afterbody lateral surface, part is between the pipe of steam-heating pipe outside the oil storage tank jar of steam heater, oil exit pipe is housed, and the oil exit pipe oil-out is loaded on steam heater afterbody lateral surface, and the oil exit pipe oil-in contacts with oil plant.

Steam-heating pipe is an eddy current screwed pipe heat exchange element.

Part has perforated shell in the oil storage tank jar of steam heater.

Technique scheme shows that the oil plant that is between heating tube at first is heated.Because heating tube adopts eddy current screwed pipe efficiently, the heat transfer medium that flows at tube wall surface is Turbulence Flow, and flow direction constantly changes, and the heat transmission is accelerated, the thermal efficiency is 3-5 times of common heating pipe, near the oil plant temperature of tube wall is improved rapidly, accelerate diffusion towards periphery, prevented that the tube wall surface oil plant from producing hot-spot, the decomposition and the coking of oil plant have been eliminated, guaranteed that the oil plant quality is constant, oil plant reduces because of intensification viscosity, the mobile enhancing.Because just device is between heating tube for oil exit pipe, this part oil plant just can be discharged at once, need not wait for after whole oil storage tank heats up and discharging.Along with the prolongation of heat time heating time, oil plant heats up from jar bottom gradually to the development of jar top, needs to discharge how many oil plants how many oil plants of just heating, and the control warm-up time just can reach, and has prevented to heat without limit, has reduced the consumption of the energy.

The utlity model has following beneficial effect:

1, firing rate is fast, the heat transfer efficiency height.

2, can quantitatively heat oil plant, how much need how many heating, save energy resource consumption.

3, localized hyperthermia, less scaling, carbonization can not appear in oil plant, have guaranteed oil quality and heater heat transfer efficiency.

4, the oil-out temperature is the highest in the oil tank, has guaranteed discharge oil plant flowability.

5, avoided repeatedly oil plant in the jar being heated, guaranteed oil plant colourity, reduced the cost that oil plant is handled.

6, improved corrosion-resistant, high temperature resistant, high pressure resistant, the good antiscale property function of device, long service life has improved the heat exchanger overall performance greatly.

7, structural design has guaranteed that oil plant flows out smoothly and " has taken out a jar " end effect preferably.

8, compact conformation, I﹠M is convenient, can not influence the safety of tank body because of the installation of heater.Comparing with U type heat exchange of heat pipe, under equal heat exchange area situation, only is about 1/2nd of U type heat exchange of heat pipe appearance and size.

9, can realize automation control, can be according to the turnover temperature and the oil drain quantity control steam amount of feeding of oil plant.
