Abstract
The utility model discloses a heat-absorbing surface structure of a chain organic heat carrier furnace. The heat-absorbing surface structure consists of an inlet container, a radiation heat-absorbing surface coil, a middle container, a ceiling pipe and an outlet container, wherein the inlet container, the middle container and the outlet container are arranged horizontally; the lower part of the radiation heat-absorbing surface coil has a single-radiation hearth structure, and the upper part of the radiation heat-absorbing surface coil has a double-radiation hearth structure; 4 to 16 coils are led out from the inlet container in parallel, are tightly wound for 1 to 3 circles side by side to form a single hearth, and are averagely classified into two parts and tightly wound for 2 to 6 circles side by side to form a double-radiation hearth; the double-radiation hearth is connected with the middle container; the middle container is connected with the ceiling pipe; the ceiling pipe is connected with the outlet container; and convection heat-absorbing surface pipes are connected to the inlet container in parallel at different heights. The heat-absorbing surface structure has large radiation heat-absorbing area, solves the problem of severe accidents caused by overheat coking of an organic heat carrier, which is resulted from the direct combustion on the bottoms of the coils, prolongs the heat exchange time when high-temperature smoke flows through a convection heat-absorbing surface region, and integrally improves the heat efficiency of the boiler.
Description
Technical field
The utility model belongs to the boiler of organic heat carrier technical field, relates to a kind of large-scale chain boiler of organic heat carrier heated face structure.
Background technology
Along with a lot of industries to the increasing of boiler of organic heat carrier demand, boiler of organic heat carrier is developed to the maximization direction by miniaturization gradually, large-scale boiler of organic heat carrier is main with chain-type mainly.At present the chain boiler of organic heat carrier since receive structure, join the restriction of combustion apparatus and transportation; In its limited space, adopt traditional heated face structure; Because radiation heating-surface, the convection heating surface arranged are on the low side, can not satisfy the requirement of large-scale chain boiler of organic heat carrier; In order to increase the radiation and convection heating surface area, by producer make up traditional radiation heating-surface structure side by side and form double-furnace structure, though increased a radiant box will; It is long-pending to have increased by one times of radiation heating-surface, but structure is not too reasonable, and coil pipe bottom, two burner hearth centers is too near from flame; Directly receive fire; Heat intensity is big, causes the overheated coking of organic heat carrier easily, and causes a serious accident.
Summary of the invention
The purpose of the utility model provides a kind of large-scale chain boiler of organic heat carrier heated face structure rational in infrastructure, to remedy the deficiency of prior art.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is:
Chain boiler of organic heat carrier heated face structure; Mainly form by inlet header case, radiation heating-surface coil pipe, middle collection case, roof tube, outlet collection case and convection heating surface pipe; Inlet header case, middle collection case, outlet collection case are and are horizontally disposed with; The bottom that it is characterized in that said radiation heating-surface coil pipe is single radiant box will structure, and its top is the biradial chamber structure, promptly draws 4～16 coil pipes side by side from the inlet header case and closely twines the single burner hearth of 1～3 circle back formation side by side; Again coil pipe is divided into two parts and closely twines 2～6 circle formation biradial burner hearths more side by side respectively; The biradial burner hearth is connected with middle collection case, and middle collection case is connected with roof tube, and roof tube is connected with outlet collection case.
Said convection heating surface pipe height arrangement side by side is connected on the inlet header case.
The beneficial effect of the utility model is, the utility model structure composition traditional radiation heating-surface structure and the advantage of double-furnace structure, carried out organic combination to both.Compare with traditional radiation heating-surface structure, it is long-pending to have increased nearly one times radiation heating-surface, has reduced the volume of boiler, is convenient to transportation, and has effectively reduced steel consumption and manufacturing cost; Because the bottom of radiation heating-surface coil pipe is single radiant box will structure; Bottom centre does not have coil pipe in the district; Directly do not receive fire, the coil pipes bottom, biradial chamber structure two burner hearth center that has solved combination composition arranged side by side directly receives the fiery problem that causes the overheated coking of organic heat carrier easily and cause a serious accident; Convection heating surface pipe height arrangement side by side is connected on the inlet header case, and the time of staying prolongs during high-temperature flue gas process convection heating surface zone, has increased heat exchanger time, and integral body has improved the thermal efficiency of boiler.

Among the figure: 1, radiation heating-surface coil pipe 2, inlet header case 3, middle collection case 4, roof tube 5, outlet collection case 6, convection heating surface pipe
The specific embodiment
According to accompanying drawing, the utility model chain organic heat carrier furnace heated face structure mainly is made up of inlet header case 2, radiation heating-surface coil pipe 1, middle collection case 3, roof tube 4, outlet collection case 5 and convection heating surface pipe 6; Inlet header case 2, middle collection case 3, outlet collection case 5 are horizontal positioned; The bottom of radiation heating-surface coil pipe 1 is single radiant box will structure; Its top is the biradial chamber structure; Promptly draw 4～16 coil pipes side by side from inlet header case 2 and closely twine the single burner hearth of 1～3 circle back formation side by side, again coil pipe is divided into two parts and closely twines 2～6 circle formation biradial burner hearths more side by side respectively, the biradial burner hearth is connected with middle collection case 3; Middle collection case 3 is connected with roof tube 4, and roof tube 4 is connected 5 with outlet collection case.How many radicals of radiation heating-surface coil pipe 1 depends on the size of circulating pump and the size of selected organic heat carrier flow velocity.The number of turns that radiation heating-surface coil pipe 1 closely twines together side by side is with to be divided into the radiation heating-surface how many number of turns that two parts closely twine side by side depend on that needs arrange long-pending big or small, and both can carry out equilibrium.
The principle of the utility model is that organic heat carrier gets into convection heating surface pipe 6 by inlet header case 2, gets into radiant coils 1 through the collection case after the heat absorption, further heat absorption, and collection case 3 and roof tube 4 absorb a part of heat again in the middle of flowing through, and flow out from outlet collection case 5 at last.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model; Those skilled in the art need not pay various modifications or the distortion that creative work can be made, and can form whole or split type boiler of organic heat carrier with other various forms of convection heating surface structures like the utility model radiation heating-surface structure, but still in the protection domain of the utility model.
