Abstract
The utility model relates to a long-acting enamel molten steel heat pipe for on-line dehydrogenation. The utility model is a whole heat pipe comprising a heat end (1), a cold end (2) and a dehydrogenating agent reaction end (3), wherein the whole heat pipe is a heat steel pipe, a middle sealing ring is arranged between the heat end (1) and the cold end (2) of the heat steel pipe, and a cold end sealing ring is arranged between the cold end (2) and the dehydrogenating agent reaction end (3); the dehydrogenating agent reaction end (3) includes a steel mesh arranged in the heat steel pipe, an on-line dehydrogenating agent arranged inside the steel mesh and a filling pipe which is arranged in the steel mesh and extends out of the heat steel pipe; a nut cap is also arranged on the filling pipe at the end extending out of the heat steel pipe; and layers of enamel are coated on the outer wall of the heat steel pipe of the heat end (1) and components arranged at the heat end (1) respectively. The acid and corrosion resistant industrial enamel is coated outside the stack gas side pipe, so that the utility model greatly improves the acid-resistant and dew point corrosion capability of the heat pipe, and improves the service life of the heat life; and under the routine designed stack gas temperature, approximate 20 DEG C can be further reduced after the heat pipe is coated with enamel, therefore the heat efficiency of a furnace is improved to a maximum extent.
Description
Technical field
The utility model relates to waste heat recovery apparatus, refers in particular to a kind of online hydrogen-removal long-acting enamel steel-water heat pipe.
Background technology
Because the high speed development of hot pipe technique, heat exchange of heat pipe uses widely industrial having obtained, and carbon steel-water heat pipe is widely used industrial because of advantages such as it have low cost of manufacture, manufacturing process is simple, exchange capability of heat is big, resistance is little, reliability is high, reparation is convenient, the adaptive temperature scope is wide.But the ability of the existing antiacid dew point corrosion of heat pipe is not very strong, usually because of managing the heat pipe failure that outer corrosion failure causes, makes exhaust gas temperature raise, and heater efficiency descends.
Summary of the invention
The purpose of this utility model is improved and is innovated at the shortcoming that exists in the background technology and problem, and a kind of online hydrogen-removal long-acting enamel steel-water heat pipe is provided.
Technical solutions of the utility model are a kind of whole heat pipes being made up of hot junction I, cold junction II and dehydrogenation agent reactive end III of structure, wherein:
Whole heat pipe is the heat pipe steel pipe, is provided with the intermediate seal ring between heat pipe steel pipe hot junction I and the cold junction II, is provided with the cold junction sealing ring between cold junction II and the dehydrogenation agent reactive end III, wherein:
Dehydrogenation agent reactive end III comprises the steel mesh that is arranged in the heat pipe steel pipe, is arranged on the online dehydrogenation agent in the steel mesh, and is arranged in the steel mesh and stretches out the filler line of heat pipe steel pipe, and wherein filler line stretches out heat pipe steel pipe end and also is provided with a block;
The heat pipe outer wall of steel pipe of described hot junction I and the set parts of hot junction I are coated with one deck enamel.
Advantage of the present utility model and beneficial effect:
The utility model is coated with the industrial enamel with antiacid corrosion outside the flue gas side pipe, can improve the ability of the antiacid dew point corrosion of heat pipe greatly, improves heat pipe service life.Can improve the thermal efficiency of stove to greatest extent reducing again under the exhaust gas temperature of conventional design about 20 ℃ behind the heat pipe enamel coating.
