Description

A kind of liquid chlorine heating and thermal insulation pipe

Technical field

The utility model relates to liquid chlorine vaporization technical field, particularly relates to a kind of liquid chlorine heating and thermal insulation pipe.

Background technique

Existing liquid chlorine is in vaporescence, adopt hot water heating pipe box in liquefied chlorine pipe outside, heat exchange pattern heating, need owing to observing, traditional heating pipe's material is simple glass pipe, but the thermal conductivity of simple glass is at room temperature about 0.75W/ (mk), it is 0.77W/m2.k 1/27 that the thermal conductivity of glass is about the thermal conductivity of 1/400 glass of copper, heat conductivity is higher, for good heat conduction environment is provided from heat conductive tube to liquid chlorine heat conduction, but simple glass pipe is also many to extraradial heat, thereby the lower vaporization rate of liquid chlorine, discarded liquid chlorine is increased, waste the energy, improve the cost of liquid chlorine vaporization.

Model utility content

In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of liquid chlorine heating and thermal insulation pipe, and its object is to improve the thermal insulation property of heating pipe, thereby improves the vaporization efficency of liquid chlorine, and reduces the vaporization cost of liquid chlorine.

The technological scheme that the utility model adopts is: a kind of liquid chlorine heating and thermal insulation pipe, thermal insulation pipe innermost layer is provided with simple glass layer, liquefied chlorine pipe is enclosed within the inner chamber that simple glass layer surrounds, thereby liquefied chlorine pipe is carried out to heat conduction, simple glass layer is outside equipped with aerogel glassy layer, aerogel glassy layer is outside equipped with thermal isolation film, the utility model is by being changed to aerogel glass by original heating pipe's outer field simple glass layer, utilize the pliable and tough of aerogel glass, environmental protection, can suppress radiation, the aerogel blanket that can construct flexibly, its thermal conductivity is extremely low, can be applicable to-200 ℃ of insulations to 1000 ℃ of temperature ranges, it is industrial pipeline, pipe-in-pipe, storage tank, the heat preserving and insulating material that the fields such as equipment are ideal, also be the most advanced in the world Novel energy saving thermal insulation material stick thermal isolation film outward at aerogel glass in the lump, reduce heating pipe's thermal radiation, and guarantee can observe at any time the vaporization situation in liquefied chlorine pipe in heating process, and then improve the vaporization efficency of liquid chlorine, reduce cost of production.

Further, thermal isolation film of the present utility model is PET material, wear-resisting, high temperature resistant, also has heat insulation function.

Further, the thickness of aerogel glassy layer is 1mm to 6mm, has good heat-shielding performance.

Further, between simple glass layer and airsetting glassy layer, be heating water cavity, so that heating liquid chlorine.

Compared with prior art, the beneficial effects of the utility model are: the utility model is by being changed to aerogel glass by original heating pipe's outer field simple glass layer, utilize the pliable and tough of aerogel glass, environmental protection, can suppress radiation, the aerogel blanket that can construct flexibly, its thermal conductivity is extremely low, can be applicable to-℃ insulation to ℃ temperature range, it is industrial pipeline, pipe-in-pipe, storage tank, the heat preserving and insulating material that the fields such as equipment are ideal, also be the most advanced in the world Novel energy saving thermal insulation material stick thermal isolation film outward at aerogel glass in the lump, reduce heating pipe's thermal radiation, and guarantee can observe at any time the vaporization situation in liquefied chlorine pipe in heating process, and then improve the vaporization efficency of liquid chlorine, reduce cost of production.

Thermal insulation pipe of the present utility model has guaranteed that liquid chlorine can obtain heat preferably, and has effectively reduced unnecessary thermodynamic loss, has improved the efficiency of liquid chlorine vaporization, and has reduced the cost of liquid chlorine vaporization, has improved the market competitiveness of enterprise.
