Technical Field
The utility model relates to a boiler equipment technical field, concretely relates to single multilayer coil pipe organic heat carrier boiler of vertical serial-type.
Background
The organic heat carrier boiler is a special boiler using heat transfer liquid as heating medium. Has low-pressure and high-temperature operating characteristics. With the development of industrial production and the progress of science and technology, organic heat carrier furnaces are continuously developed and applied. Although the working pressure of the organic heat carrier furnace is relatively low, the temperature of the heat transfer fluid in the furnace is high, and most of the heat transfer fluid has the characteristics of flammability and explosiveness, once leakage occurs in the process of operation, accidents such as fire hazard, explosion and the like can be caused, and even casualties and property loss can be caused. Therefore, high attention must be paid to the safe operation and management of the organic heat carrier furnace.
At present, the inner coil pipe and the outer coil pipe of a common vertical organic heat carrier boiler are usually connected in parallel, and due to the design, the temperatures of the inner coil pipe and the outer coil pipe are not uniform in the actual use process, so that the temperature in the pipes is not easy to control, combustion equipment is enabled to work frequently, and the energy consumption and the operation cost are wasted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a single multilayer coil pipe organic heat carrier boiler of vertical series-type to reach energy-conserving efficient purpose.
In order to solve the technical problem, the utility model provides a vertical serial-type single multilayer coil pipe organic heat carrier boiler, which comprises a boiler body, wherein an outer coil pipe which is coiled from bottom to top is arranged in an inner cavity of the boiler body, and an inner coil pipe is arranged at the inner side of the outer coil pipe; and is
The outer coil pipe and the inner coil pipe are connected in series and vertically through a connecting pipe;
a second gap for the smoke to pass through is arranged between the outer coil pipe and the inner wall of the furnace body;
a first gap for passing through smoke is arranged between the outer coil pipe and the inner coil pipe.
Wherein, interior coil pipe and outer coil pipe coaxial axle set up.
Wherein, outer coil pipe and interior coil pipe are the heliciform and spiral and set up.
Wherein, the bottom of interior coil pipe is provided with the combustor that lets in steam to interior coil pipe inboard.
Wherein the first gap has a gap width of 125 mm.
The beneficial effects of the utility model are that, the utility model provides a single multilayer coil pipe organic heat carrier boiler of vertical serial-type, through the circuit trend and the connected mode that change interior coil pipe and outer coil pipe, make the high temperature radiation heating surface conduction oil in the pipeline get into from the convection section, the low temperature oil that make full use of convection section heating gets into the high temperature section radiation and reheats, has improved the uniformity of organic heat carrier boiler temperature, realizes the accurate regulation and control of temperature, reaches energy-conserving efficient purpose.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Examples
As shown in fig. 1, the embodiment provides a vertical serial-type single multilayer coil pipe organic heat carrier boiler, which includes a boiler body 1, an outer coil pipe 2 which spirals from bottom to top is arranged in an inner cavity of the boiler body 1, and an inner coil pipe 3 is arranged on the inner side of the outer coil pipe 2; the outer coil pipe 2 and the inner coil pipe 3 are connected in series and vertically through a connecting pipe 4; a first gap 5 for passing through smoke is arranged between the outer coil 2 and the inner coil 3, and a second gap 6 for passing through smoke is arranged between the outer coil 2 and the inner wall of the furnace body. The bottom of the inner coil pipe 3 is provided with a burner 7 which leads hot gas to the inner side of the inner coil pipe 3, and the high-temperature flue gas after burning passes through a first gap 5 between the inner coil pipe 3 and the outer coil pipe 2 and then is discharged out of the furnace body 1 from a second gap between the outer coil pipe 2 and the furnace body 1 through a flue gas outlet 8.
Further, inner coil pipe 3 and outer coil pipe 2 set up with the axle center, and the flue gas passageway is even to be passed through, improves heat-conduction efficiency.
Further, the outer coil 2 and the inner coil 3 are both spirally and spirally arranged.
Further, the spacing width of the first gap 5 is 125mm, and in the using process, when the gap between the inner coil 3 and the outer coil 3 is too large, the flue gas channel is too wide, which will cause the flow velocity of the flue gas to slow down, thereby affecting the heat transfer efficiency; control the clearance between interior coil pipe 3 and the outer coil pipe 2 at 125mm to the velocity of flow of guarantee flue gas has improved this embodiment and hot-air's heat transfer efficiency in a higher heat transfer interval.
When in work, the heat exchange process is as follows: the combustor 7 generates high-temperature flame, the inner ring of the inner coil 3 radiates to release heat, after oil liquid absorbs heat in the inner coil 3, high-temperature smoke flows to a first gap between the inner coil 3 and the outer coil 2 again, heat exchange is carried out in a second heat exchange return stroke, then the smoke continues to diffuse to the outside, enters a second gap between the outer coil 2 and the side wall of the furnace body 1 to exchange heat, heat exchange is carried out for the third time, and after heat exchange is completed, the smoke is discharged from the smoke outlet 8. The oil liquid flow is as follows: the low-temperature oil enters the outer coil pipe 2, enters the inner coil pipe 3 through the connecting pipe 4 after being filled with the oil, and flows out of the oil outlet pipe stably after absorbing heat. The outlet oil source is unique, and the oil temperature is stable.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
