Description

Be built in the parallel finned tube steam superheater of multitubular boiler front smoke box
Technical field
The present invention relates to a kind of multitubular boiler, be specifically related to a kind of steam superheater.Be built in multitubular boiler front smoke box.Belong to heating equipment technical field.
Background technology
Boiler is to utilize the chemical energy of fuel or the heat energy of other energy, water is heated to the thermal power transfer equipment of certain parameter.Conventional steam boiler can only be heated as water the saturated vapor under rated pressure, under rated pressure, when user need to use the superheated steam of higher temperature, just need in boiler, increase superheater parts.Superheater be boiler for improving the parts of vapor (steam) temperature, its objective is the enthalpy that improves steam.
At present when multitubular boiler front smoke box is arranged superheater, in the situation that pressure is certain, while needing superheat steam temperature higher, the heat exchange area that tradition bare-tube superheater needs is larger, during layout, cause front smoke box volume excessive, it is large that boiler overall volume becomes, and highly uprises, and increased transport difficulty and cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of parallel finned tube steam superheater that is built in fuel oil, gas multitubular boiler front smoke box that can dwindle superheated steam boiler front smoke box volume is provided.
The purpose of this utility model is achieved in that a kind of parallel finned tube steam superheater that is built in multitubular boiler front smoke box, comprise saturated vapor inlet tube, import header, snakelike spiral fin coil, outlet header and superheated steam gathering tube, described saturated vapor inlet tube and superheated steam gathering tube respectively have one, import header, snakelike spiral fin coil and outlet header respectively have two groups, import header between two groups, snakelike spiral fin coil and outlet header adopt and are arranged in parallel, wherein every group of snakelike spiral fin coil is to be listed as or the snakelike spiral fin coil of stagger arrangement forms by some alignments, import header is connected with saturated vapor inlet tube, snakelike spiral fin coil is fixedly mounted in multitubular boiler front smoke box, snakelike spiral fin coil two ends are connected with outlet header with import header respectively, two outlet headers are connected with superheated steam gathering tube.
Saturated vapor enters two import headers by pipeline from the parallel connection of saturated vapor inlet tube, enter again two snakelike spiral fin coils, after the abundant heat exchange of snakelike spiral fin coil and flue gas, saturated vapor changes superheated steam into, by two outlet headers, enter superheated steam gathering tube again, reach the superheated steam of instructions for use, and enter heat distribution pipe network by main-steam outlet.
The beneficial effects of the utility model are:
1, the utility model superheater adopts parallel snakelike spiral fin coil and flue gas heat exchange, has increased heat exchange area and has improved heat exchange efficiency;
2, contrast light pipe type superheater, when importing and exporting, the steam temperature difference is identical, and in the identical situation of other operating mode, the quantity of the heat exchanger tube that the utility model is used is less than bare-tube superheater, has also reduced welding job amount;
3, owing to reducing heat exchanger tube quantity, when design front smoke box, can dwindle front smoke box size, thereby dwindle boiler overall dimensions, reduced transport difficulty and cost;
4, the utility model superheater adopts parallel snakelike Influences of Structure of Spiral Finned Tube, has increased steam circulation area, applicable to jumbo large-scale fire tube superheated steam boiler;
5, the utility model superheater is built in multitubular boiler front smoke box, can realize chafing dish superheated steam boiler whole Transporting and dispatch from the factory, and has reduced boiler erection work on the spot amount.

The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is structural representation of the present utility model (superheated steam gathering tube does not show).Fig. 2 is the top view of Fig. 1.Fig. 3 is the A-A cutaway view of Fig. 1.By Fig. 1, Fig. 2 and Fig. 3, can be found out, the utility model is built in the parallel finned tube steam superheater of multitubular boiler front smoke box, mainly saturated vapor inlet tube 8, import header 1, snakelike spiral fin coil 3, outlet header 2, support member 4, sealing plate 6, outlet(discharge) flange 5 and superheated steam gathering tube 7, consists of.As Fig. 4 and Fig. 5.Described saturated vapor inlet tube 8 and superheated steam gathering tube 7 respectively have one, import header 1, snakelike spiral fin coil 3 and outlet header 2 respectively have two groups, import header 1 between two groups, snakelike spiral fin coil 3 and outlet header 2 all adopt following current to be arranged in parallel, two import headers 1 are connected with saturated vapor inlet tube 8 by the first flange, between snakelike spiral fin coil 3, adopt support member 4 to be fixedly mounted on boiler front smoke box 9 places, snakelike spiral fin coil 3 two ends are welded on respectively on import header 1 and outlet header 2, two outlet headers 2 are connected with superheated steam gathering tube 7 by the second flange.Sealing plate 6 surrounds snakelike spiral fin coil 3 heat exchanging part, sealing plate 6 lower ends and front smoke box 9 seal weldings, upper end and outlet(discharge) flange 5 seal weldings, flue gas is from smoke pipe out enters front smoke box 9, after the heat exchange region surrounding by sealing plate 6 from bottom to top and 3 heat exchange of snakelike spiral fin coil, then flow out and enter next stage heat transmission equipment by outlet(discharge) flange 5.
Saturated vapor enters two import headers 1 by pipeline from 8 parallel connections of saturated vapor inlet tube, enter again two groups of snakelike spiral fin coils 3 that are arranged in parallel, after snakelike spiral fin coil 3 and the abundant heat exchange of flue gas, saturated vapor changes superheated steam into, by two outlet headers 2 that are arranged in parallel, enter superheated steam gathering tube 7 again, the superheated steam that reaches instructions for use enters heat distribution pipe network by main-steam outlet.
What more than introduce is the structural configuration mode of following current parallel connection.If saturated vapor inlet tube 8 exchanges with outlet header 2 with superheated steam gathering tube 7, import header 1, be that former saturated vapor inlet tube 8 becomes superheated steam gathering tube 7, former superheated steam gathering tube 7 becomes saturated vapor inlet tube 8, former import header 1 becomes outlet header 2, former outlet header 2 becomes import header 1, and superheater structural configuration mode is that adverse current is arranged in parallel so.
The utility model is built in the parallel finned tube steam superheater of multitubular boiler front smoke box, has that two kinds of arrangements---following current is arranged in parallel with adverse current and is arranged in parallel.Wherein following current is arranged in parallel mode and is applicable to the chafing dish superheated steam boiler that overtemperature is not too high, and adverse current is arranged in parallel mode, superheated steam can be brought up to higher temperature, is applicable to the chafing dish superheated steam boiler that the degree of superheat is higher.
