Abstract

The utility model discloses a radiation heated surface structure for a large horizontal square box coal burning organic heat carrier boiler, which is composed of an inlet collecting tank, a coil pipe on a radiation heated surface, a middle collecting tank, a ceiling pipe and an outlet collecting tank, wherein the inlet collecting tank, the middle collecting tank and the outlet collecting tank are all arranged horizontally. The lower part of the coil pipe on the radiation heated surface forms a single radiation hearth structure, and the upper part forms a double radiation hearth structure. Namely, after 4-16 coil pipes are led out of the inlet collecting tank and tightly wound for 1-3 turns side by side, a single hearth is formed. Then, the coil pipes are averagely divided into two parts and respectively and tightly wound for 2-6 turns side by side, and thus, a double radiation hearth is formed. The double radiation hearth is connected with the middle collecting tank connected with the ceiling pipe, and the ceiling pipe is connected with the outlet collecting tank. The utility model has the advantage of large radiation heated area. The utility model solves the problem that the direct fire heating of the bottom of the coil pipes is easy to result in serious accidents caused by the overheat coking of the organic heat carrier. The utility model is suitable for being used on horizontal square box coal burning organic heat carrier boilers of 6 million-12 million kcal / hour.

Description

Large-size horizontal square chest coal burning organic heating medium boiler radiation heating-surface structure
Technical field the utility model belongs to the boiler of organic heat carrier technical field, relates to a kind of large-size horizontal square chest coal burning organic heating medium boiler radiation heating-surface structure.
Background technology along with a lot of industries to the increasing of coal burning organic heating medium boiler demand, the coal burning organic heating medium boiler is developed to the maximization direction by miniaturization gradually, large-scale boiler of organic heat carrier is mainly based on horizontal square chest.At present, horizontal square chest coal burning organic heating medium boiler since be subjected to structure, join the restriction of combustion apparatus and transportation, in its limited space, adopt traditional radiation heating-surface structure, because the radiation heating-surface of arranging is on the low side, can not satisfy the requirement of large-size horizontal square chest coal burning organic heating medium boiler; Long-pending in order to increase radiation heating-surface, by producer traditional radiation heating-surface structure made up side by side 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 be subjected to 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 this utility model provides a kind of large-size horizontal square chest coal burning organic heating medium boiler radiation heating-surface structure rational in infrastructure, to remedy the deficiencies in the prior art.
To achieve these goals, the utility model large-size horizontal square chest coal burning organic heating medium boiler radiation heating-surface structure is to improve realization on the basis of existing technology, it is by the inlet header case, the radiation heating-surface coil pipe, middle collection case, roof tube and outlet collection case are formed, the inlet header case, middle collection case, outlet collection case is and is horizontally disposed with, its main points are that the bottom of radiation heating-surface coil pipe is single radiant box will structure, its top is the biradial chamber structure, promptly draw 4~16 coil pipes side by side and closely twine the single burner hearth of 1~3 circle back formation side by side from the inlet header case, 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, middle collection case is connected with roof tube, and roof tube is connected with outlet collection case.
The utility model structure composition traditional radiation heating-surface structure and the advantage of double-furnace structure, both have been carried out organic combination.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 be not subjected to fire, the coil pipes bottom, biradial chamber structure two burner hearth center that has solved combination composition arranged side by side directly is subjected to the fiery problem that causes the overheated coking of organic heat carrier easily and cause a serious accident.
The utility model radiation heating-surface structure can be formed whole or split type horizontal square chest coal burning organic heating medium boiler with other various forms of convection heating surface structures, be applicable to 600~1,200 ten thousand kilocalories/hour horizontal square chest coal burning organic heating medium boiler adopt.
Description of drawings Fig. 1 is a radiation heating-surface structural front view of the present utility model;
Fig. 2 is a radiation heating-surface structure left view of the present utility model;
Fig. 3 is a radiation heating-surface structure vertical view of the present utility model.
Among the figure: 1, radiation heating-surface coil pipe 2, inlet header case 3, middle collection case 4, roof tube
5, outlet collection case
The specific embodiment with reference to the accompanying drawings, the utility model large-size horizontal square chest coal burning organic heating medium boiler radiation heating-surface structure 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; 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 and closely twine the single burner hearth of 1~3 circle back formation side by side from inlet header case 2, 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 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 coil pipe 1 closely twines together side by side and 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, both can carry out equilibrium.
Principle of the present utility model is that the organic heat carrier after absorbing heat from the convective region enters radiant coils 1 by 2 shuntings arranged side by side of inlet header case, further heat absorption, and middle case 3 and the roof tube 4 of collecting of flowing through absorbs a part of heat again, flows out from outlet collection case 5 at last.
