The engineering thermal insulation heat preservation technology is widely used in a plurality of industries such as chemical industry, electric power, construction engineering, domestic heating, and simple insulating structure generally can be divided into the internal layer thermal insulation layer and the protective coating of going out.In chemical industry process units such as equipment, pipeline being used more insulating structure is to wrap up certain thickness thermoinsulation material (conventional thermoinsulation material or low thermal conductivity thermoinsulation material according to device design and running temperature at its equipment, pipe surface, as rock wool, glass fibre, alumina silicate, rock wool, rare earth etc.), again at thermoinsulation material surface parcel layer of metal shell, to prevent or to reduce the thermal loss of device.No matter be to adopt conventional thermoinsulation material or adopt the low thermal conductivity thermoinsulation material, all exist significantly not enough as thermal insulating material.The deficiency that adopts conventional thermoinsulation material to be incubated is because heat conduction, heat storage coefficient and the loose physical property of conventional thermoinsulation material, it exists thermal radiation, thermoconvection and heat transmission etc. unavoidablely, consequent heat loss is excessive, causes heat insulation effect not good too high with the chemical production device hear rate; The deficiency that adopts the low thermal conductivity thermoinsulation material to be incubated is the selling at exorbitant prices of low thermal conductivity thermoinsulation material, be unfavorable for reducing production costs, and operational method is also comparatively loaded down with trivial details, is unfavorable for implementing.
And for example the patent No. is that the Chinese utility model patent of ZL200820065148.3 (notification number is 201277414Y) discloses a kind of thermal insulation engineering thermal insulation structure, it comprises dismountable adiabatic bagging and outer layer metal protecting crust, adiabatic bagging inside is provided with one deck adiabator layer at least, and the packed jointing of joining the parts of thermodynamic system of jacket is provided with first buckling part, the outer layer metal protecting crust is installed in the outside of adiabatic bagging, and the jointing two joints is provided with second buckling part.This insulating structure has effectively improved the recycling rate of waterused of energy-saving effect and thermal insulating material, and comprehensive breakthrough has been arranged on thermal insulation property, and is comparatively complicated but deficiency is an insulating structure, and also has further improved space in the selection to heat-insulation material.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of at the above-mentioned state of the art and can effectively improve the device heat insulation effect, reduce the chemical industry equipment thermal insulating material that the device hear rate can reduce production costs simultaneously.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of chemical industry equipment thermal insulating material, it is characterized in that comprising at least two thermal insulation layers, and adjacent thermal insulation layer adopts the thermoinsulation material of different thermal conductivitys.Further, according to different device running temperature and the heat insulation effect that will reach, each thermal insulation layer can be selected different thickness.
Preferably, described thermal insulation layer from-inner-to-outer is followed successively by internal layer thermal insulation layer, mesosphere thermal insulation layer, outer thermal insulation layer, described internal layer thermal insulation layer and outer thermal insulation layer adopt first thermoinsulation material, described mesosphere thermal insulation layer adopts second thermoinsulation material, and the thermal conductivity of described second thermoinsulation material is less than the thermal conductivity of first thermoinsulation material.Owing to though the thermoinsulation material adiabatic heat insulating effect that thermal conductivity is less is better, but price is higher, has only the mesosphere thermal insulation layer to adopt the second less thermoinsulation material of thermal conductivity in this technological scheme, like this, can realize adiabatic heat insulating effect preferably, reduce cost of production again.Certainly, also can the internal layer thermal insulation layer and outer thermal insulation layer adopt the second less thermoinsulation material of thermal conductivity, and the mesosphere thermal insulation layer adopts first thermoinsulation material, can possess preferably adiabatic heat insulating effect equally and reduces production costs.
Further, be provided with the fastened layer that to tighten described internal layer thermal insulation layer between described internal layer thermal insulation layer and the mesosphere thermal insulation layer.Under the effect of fastened layer, can make the gap between internal layer thermal insulation layer and apparatus surface less, thereby reduce the device heat loss.
Described fastened layer can adopt multiple fastener material, and preferably, it is the wire netting of 5～30mm that described fastened layer adopts the aperture.
For further improving the heat insulation effect of device, the outer surface of described outer thermal insulation layer is coated with a metal shell.Metal shell can further be blocked the waste heat transmission of outer thermal insulation layer and the hot/cold transmission that external environment causes.
Compared with prior art, advantage of the present utility model is: this chemical industry equipment thermal insulating material, adopted the thermal conductivity difference of the thermoinsulation material of at least two thermal insulation layers and adjacent thermal insulation layer, only need to adopt the second less thermoinsulation material of thermal conductivity at indivedual thermal insulation layers, can both improve the heat insulation effect of device, reduce the cost of production of insulating structure again.
