Abstract
The invention discloses an oil storage tank heating pipe diffuser which comprises a shell. The shell comprises an end portion, a neck portion and a concave portion. The oil storage tank heating pipe diffuser is of an overall structure. The concave portion is of a circular transition structure. The oil storage tank heating pipe diffuser is further provided with an air-water separation plate which is arranged between the concave portion and an inlet. The section of the neck portion is in an oval shape. The oil storage tank heating pipe diffuser has the advantages that connectors are in large-radius circular arc connection transition, stress produced in the production process and diffused stress diffused in the high temperature operation conditions are eliminated, the overall strength of the diffuser is improved, and impact abrasion produced in the using process is reduced; the air-water separation plate is arranged in the diffuser, generated bubbles and impact abrasion caused by heating media on the diffuser are effectively reduced on the working conditions, the heat energy utilization rate is improved, and the hardness, the wear resistance, corrosivity and weldability are improved; the neck portion has the oval-shape section, so that diffuser abrasion is reduced, no medium residue exists, and electrochemical intergranular corrosion is completely eradicated.
Description
Technical field
The present invention relates to oil equipment field, specifically a kind of temperature booster, is more specifically a kind of heating pipe decollator.
Background technology
Petrol storage tank is the oil storage facility that Oil production sites is conventional, and be also one of visual plant in oil exploration industry, its performance and using state directly can have influence on economic benefit and the ecology environment in oil field.Oil storage tank heater is with solving the heating problems of oil tank Crude Oil when ambient temperature is low; A lot of containing corrosive medium in crude oil, media chemistry corrosion and electrochemical corrosion stronger.Petrol storage tank heating pipe decollator is in operation and bears high pressure, high temperature, high corrosive environment, except adding hot corrosion, also has the corrosion that crude oil medium factor causes, weld decay, erosive wear etc.Oil storage tank heater comprises decollator, heating calancria, standpipe, push pipe and end connection pipe etc.The effect of decollator: heating calancria counterpart docked, make it compact conformation, installs, overhauls conveniently, be conducive to weld bond X-ray examination.The effect of decollator: (1) gos deep into tank bottom along petrol storage tank radial direction, makes heating calancria form large S-shaped temperature booster with bend pipe; (2) thermal medium (steam) walks tube side, steadily be diverted in heating pipe by decollator, fluid is made to produce turbulent flow when surfaces externally and internally flows, produce strong concussion and scouring action, flow direction constantly changes, high temperature oil product fluid near heating pipe surface is constantly changed, thermal insulation layer thinning to such an extent as to damage, along with heat transmission is accelerated, fluid microscopic eddies is strengthened, and the diffusion of oil product internal heat is strengthened, and the fluid being close to wall surface can not be made to produce localized hyperthermia overheated, oil product was both fully heated, the possibility of Non-carbonized coking again, decomposition.As shown in Figure 1, its end adopts welded structure to existing petrol storage tank heating pipe decollator structure, therefore, easily produces weld decay, in addition, due to unreasonable structure, cannot overcome above-mentioned shortcoming.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of petrol storage tank heating pipe decollator, can effectively overcome above-mentioned defect, concrete structure is as follows:
A kind of petrol storage tank heating pipe decollator, comprise housing, described housing comprises end, neck and recess, and described petrol storage tank heating pipe decollator is integral structure; Described recess is rounded transitional structure; Described petrol storage tank heating pipe decollator also arranges gas-water separation plate, and described gas-water separation plate is arranged between recess and import, and described neck cross section is ellipse.
Described petrol storage tank heating pipe decollator material adopts welded structure steel casting iron ZG275-485H;
Advantage of the present invention is:
Adopt the circular sliding slopes transition of large radius between interface, the stress eliminated in producing produces and the stress dispersion of decollator under high-temperature operation condition.Improve decollator bulk strength, reduce impact wear in using;
Devise gas-water separation plate in decollator, effectively reduce heating medium under service conditions and decollator impact wear and bubble are produced, improve heat energy utilization;
Decollator material adopts welded structure steel casting iron ZG275-485H, utilizes silicon, manganese combination, strengthening matrix, effectively improves steel and bends/strong (σ s/ σ b) ratio, improves hardness, resistance to abrasion, corrosive property, weldability are good;
Fluid is by the caliber of same area, and its flow velocity is relevant with caliber place cross sectional shape; Therefore, neck adopts ellipse Cross section Design, after effectively solution decollator cycle of operations terminates, heating medium heat is all released in the heater, namely make full use of " gasification potential ", make all to be discharged with the state of water by the steam of temperature booster, stop electrochemistry intergranular corrosion.In the loop of discharging, guarantee to exist without steam, therefore produce without " water attack ", effectively prevent temperature booster and make condensed water enter oil product because of " water attack " destruction to lead to interior " bumping " accident of tank.
