Abstract
The utility model discloses a membrane wall structured hydrogen gas boiler, which comprises a boiler body. A chimney is connected to the top of the boiler body. A combustion space, namely a hearth, of the boiler body is in a membrane water cooled wall tube structure, the upper portion of the hearth is provided with an explosion-proof door, the boiler body is provided with a smoke tube as an upper heated face, the smoke tube is connected with an upper tube plate and a lower tube plate connected to a boiler shell cylinder, and the lower tube plate is connected with the hearth membrane water cooled wall tube and a downcomer. The membrane-wall boiler combusting hydrogen gas completely solves the problems that energy resources are wasted in chlor-alkali enterprises in emptying hydrogen gas, saline water and caustic soda require vapor for heating in chlor-alkali production, danger resources are created in emptying of a great amount of hydrogen gas, and the like. The membrane wall structured hydrogen gas boiler is high in safety performance and high in operational automation level.
Description
Technical field
The utility model relates to field of boilers, especially relates to a kind of hydrogen boiler.
Background technology
In recent years, the development of China chlorine industry was very fast, but had quite a few chlor-alkali production producer not have the hydrogen downstream product, a large amount of hydrogen that produce in the chlor-alkali production except synthetic hydrochloric acid spends seldom a part, all the other most of hydrogen emptying in vain.Both waste this very energy of cleaning of hydrogen, had inflammable and explosive danger again.
Hydrogen is as the fuel of boiler, compare with conventional gas fuel such as natural gas, town gas, liquefied petroleum gas etc., explosive is its maximum characteristics, the hydrogen explosion concentration limit is wide to reach 4% ~ 80%, therefore, still on installation, the operation very high requirement has been proposed all from structure of boiler body, combustion system, automatic control.
Summary of the invention
The purpose of this utility model is to provide a kind of chlor-alkali enterprise that makes full use of by the membrane wall boiler of the byproduct hydrogen of emptying.
The technical solution of the utility model is:
Membrane wall structure hydrogen boiler, comprise boiler body, the boiler body top is connected with chimney, the combustion space of described boiler body is that burner hearth adopts the fin panel casing tubular construction, upper furnace is provided with explosion proof door, and boiler body is provided with smoke pipe, and smoke pipe is the top heating surface, smoke pipe links to each other with lower perforated plate with upper perforated plate on being connected the shell cylindrical shell, and lower perforated plate links to each other with burner hearth monowall tube and down-comer.
Be provided with turbolator in the described smoke pipe.
Described shell cylindrical shell is provided with heat-insulation layer outward, and the heat-insulation layer outside is provided with outer casing.
Described energy-saving appliance is installed on above the shell cylindrical shell, and energy-saving appliance adopts the coiled structure of crawling.
Structure of the present utility model:
(1) structure of boiler body is vertical layout, and its body is supported on the steelframe at the middle part, and during the boiler operatiopn, body can freely make progress and expand downwards.On the chimney support, top steelframe, be provided with expansion joint between chimney and the body simultaneously.
(2) as the burner hearth of boiler body combustion space and radiant heat transfer important component part, adopt film water cold wall structure, it is long-pending to have improved furnace heating surface greatly, and water screen tube is outward a light heat insulation material, and the heat-insulation layer outside is a backplate.Upper furnace is provided with explosion proof door.
(3) convection heating surface adopts the smoke pipe structure, and smoke pipe links to each other with last lower perforated plate on being connected the shell cylindrical shell, is provided with turbolator in the smoke pipe, increase flue gas resistance, augmentation of heat transfer.Simultaneously tedge and down-comer link to each other in lower perforated plate and the burner hearth.
(4) the shell cylindrical shell is outward a heat-insulation layer, and the outer steel plate of heat-insulation layer is the outer casing of material.
(5) energy-saving appliance is installed on above the shell cylindrical shell, and structure adopts the coiled that crawls.
It is the membrane wall boiler of fuel with the pure hydrogen that the utility model provides a kind of, fully solved in the energy waste, chlor-alkali production of chlor-alkali enterprise emptying hydrogen salt solution and the caustic soda contradictions such as needing steam, a large amount of dangerous sources of emptying hydrogen of heating, and the security performance height, self energy operational degree height.
The beneficial effect that the utility model brings is as follows:
(1) chamber design has enough volumes, guarantees that hydrogen stops time enough in stove, thereby guarantees that combustion of hydrogen efficient is high;
(2) the boiler integral vertical type is arranged, flue gas flow is unobstructed, and no dead angle can prevent that hydrogen from gathering, and prevents detonation;
(3) water-cooling wall of membrane type structure provides sufficient heating surface, has greatly improved the thermal efficiency of boiler, and hydrogen is fully utilized.
