Abstract
The utility model relates to a ring fume duct type heating stove for oil extraction, collection and transportation. The utility model is composed of a metal casing body 3, a burner 1, a chimney 7, an explosion-proof door 8, a lining 9, a sewage discharging pipe 11 and a fire brazier 10, a radiation stove pipe 2, convection stove pipes 5, 6 and a convection plug 4 which are arranged in the casing body 3. The convection stove pipes and the radiation stove pipe of the heating stove form a whole without elbow connection. Thus, the utility model has the advantages of simple structure and easy manufacture, and besides, the utility model is favorable to energy saving, consumption decrease and production cost decrease; a ring fume duct formed between a stove body and the convection plug arranged in the stove body can enlarge convection heat exchange area and improve the stove efficiency.
Description
The utility model relates to a kind of heater that is used for oil exploitation, the defeated process of collection: ring smoke runner tubular heater.
Heating furnace is the defeated requisite visual plant of process of oil exploitation, collection.The on-the-spot at present heating furnace that uses has multiple structure typess such as water jacket furnace, heat pipe oven, and wherein tubular heater is one type newer over nearly 10 years.Tubular heater of the prior art is to utilize the medium that is flowing in the flame that forms after the fuel combustion and the high-temperature flue gas directly-fired kiln pipe, boiler tube generally is divided into two sections of radiant section and convection sections, the form of structure of heating tube in section of convection chamber mostly is cuboid, it is many that its shortcoming one is that boiler tube turns round, and the local resistance of media flow is big; The 2nd, the welding workload of elbow is big, and nondestructive inspection quantity is many, and difficulty is big, the expense height; The 3rd, carry out the transition to the convection section complex structure of cuboid by the columnar width of cloth section of penetrating, steel consumption is big, the manufacturing cost height.Because the existence of above-mentioned shortcoming makes the scope of application of existing tubular heater be restricted, economic benefit is affected.
The purpose of this utility model be to provide a kind of structure comparatively simple, be easy to make, steel consumption is few, manufacturing cost is lower ring smoke runner tubular heater.
The utility model is to realize like this.This kind tubular heater convection section and radiant section all are made into spirality, and convection coil is the continuity of all-purpose furnace pipe.In order to strengthen heat convection, improve flue gas flow rate, in the center cavity that is centered on by helix tube, add the cylindrical convection current plug of a heat-resisting thermal insulation.In the case, flame that fuel forms after by burner combustion and high-temperature flue gas are through the outer body of heater cavity of all-purpose furnace pipe, the circular passage of flowing through and forming by body of heater lining and convection current plug, behind the transversal flow convection coil, through convection current beyond the Great Wall portion's smoke ventilator enter chimney and enter atmosphere, thereby the heat convection area is increased, and heating-furnace is imitated and is improved.
Advantage of the present utility model is that convection coil and all-purpose furnace pipe constitute one, do not need to connect with elbow, thereby simple in structure, steel consumption is few, be easy to make, and weld seam is few, and manufacturing and nondestructive inspection expense are low.Simultaneously, owing to need not to adopt elbow to connect, thereby the media flow resistance is little, the delivery pump energy consumption reduces, and helps saving energy and reduce the cost and reducing production costs.In addition, the ring smoke runner between body of heater and the convection current plug can increase the heat convection area, improves stove and imitates.
Accompanying drawing is a general structure schematic diagram of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of burner 1, all-purpose furnace pipe 2, metal shell 3, convection current plug 4, convection coil 5,6, chimney 7, explosion proof door 8, lining 9, fire pot 10 and blow-off pipe 11.Its structure, the assembling feature as follows: metal shell 3 inwalls are provided with lining 9, and chimney 7 is equipped with at the top, and top one side is provided with explosion proof door 8, and the bottom is provided with burner 1, and pick out blow-off pipe 11; Housing 3 inner bottom parts are provided with fire pot 10, and all-purpose furnace pipe 2 is equipped with at its seat of honour, are provided with convection current plug 4 in the all-purpose furnace pipe 2 top center cavities, are arranged with the convection coil 5,6 that is connected with all-purpose furnace pipe top respectively around it.Wherein, metal shell 3 is a vertical or horizontal hollow cylinder, and its top, sidewall and bottom are respectively equipped with the circular hole that chimney 7, explosion proof door 8, burner 1, blow-off pipe 11 are installed.Convection current plug 4 is cylindrical, adopts interior filling thermal insulation material alumina silicate of refractory cement shell and rock wool to make, and its top has a plurality of apertures for the flue gas circulation.All-purpose furnace pipe 2 is a spirality, and its top picks out respectively can be for the convection coil 5,6 of two kinds of different medium circulations, heating, and all-purpose furnace pipe, convection coil all adopt petroleum cracking tube or boiler tube to make.Lining 9 adopts heat-resisting thermal insulation material rock wool and alumina silicate fibre bonding to make.Miscellaneous part (burner 1, chimney 7, explosion proof door 8, fire pot 10, blow-off pipe 11) is general part.
