Abstract
The utility model discloses a magnetic adsorption type exterior insulation device which comprises an inner waterproof layer 1, an outer waterproof layer 2, a magnet 3 and heat insulation material 4, wherein the magnet 3 and the heat insulation material 4 are clamped between the inner waterproof layer 1 and the outer waterproof layer 2. When the metal of the housing of equipment is overheated because the liner of the equipment is damaged, the magnetic force of the magnetic adsorption type exterior insulation device disappears, and an outer insulating layer falls out automatically, so as to prompt an overtemperature point and avoid the occurrence of an accident.
Description
Technical field
The utility model relates to the absorbent-type external heat preserving device, particularly a kind of overtemperature magnetic force absorbent-type external heat preserving device that comes off automatically.
Background technology
Regenerator at petrochemical industry and Coal Chemical Industry industry fluidization reaction-regeneration system, regenerator three-stage cyclone separator or reactor, the reactor three-stage cyclone separator, heating furnace, owing to there is Korrosionsmedium, there is stress corrosion phenomena in metal shell, the situation of stress corrosion cracking has often taken place in the equipment of operation, therefore, improve the housing metal temperature, make it to be higher than the dew-point temperature of 120～140 ℃ of device interior Korrosionsmediums, the device interior Korrosionsmedium can not condensed in inner walls, thereby can't form dew point stress corrosion environment, avoid causing the metal shell stress corrosion cracking.
Improve the housing tube wall temperature, two kinds of ways arranged usually:
Way one. attenuate enclosure interior liner thickness, increase the heat output of interior media to metal shell, in the ordinary course of things, satisfy the requirement that the housing metal temperature is higher than device interior Korrosionsmedium dew-point temperature.Yet this way is that a large amount of heat energy loses in vain, makes the equipment operating environment more abominable.And meet under the situation of extreme climates such as sleet strong wind, this method also can't guarantee that wall temperature can reach temperature required, just there is the chance that produces dew point corrosion in Korrosionsmedium like this.
Way two. the enclosure interior liner thickness is constant or thicken slightly, and hull outside adopts fire-proof heat-insulating material to carry out outer insulation for the overtemperature on the basis type insulation material that comes off automatically, and as described in Chinese patent ZL00237765.9, but this technology has the deficiency of the following aspects:
1. difficulty of construction is big, and temperature control is difficult to accurately;
2. be difficult to waterproof, sleety weather is unreliable;
3. because it is non-dismountable, influences apparatus casing and regularly detect;
4. material is comparatively thick and heavy, easily hurts sb.'s feelings when coming off;
5. the overtemperature inefficacy material of Tian Jiaing easily causes in advance and comes off.
The utility model content
The purpose of this utility model provides the outer heat preservation technology of a kind of magnetic force absorbent-type, to solve the deficiencies in the prior art.For addressing the above problem a kind of magnetic force absorbent-type of the utility model external heat preserving device.
A kind of magnetic force absorbent-type external heat preserving device that the utility model proposes, form by magnet, insulation material, interior exterior waterproof coating, be characterised in that: interior exterior waterproof coating is clipped in the middle magnet and insulation material, attemperator thickness is 4～15mm, long and wide is 300～900mm, decides according to the device diameters size.A kind of magnetic force absorbent-type external heat preserving device magnet that the utility model proposes takes off magnetic automatically when 300 ℃～340 ℃ scopes of temperature, magnetic force absorbent-type external heat preserving device can come off from wall automatically.
The characteristic that a kind of magnetic force absorbent-type external heat preserving device that the utility model proposes utilizes the magnet overtemperature to take off magnetic realizes that overtemperature heat-insulation and heat-preservation material comes off automatically, reaches the purpose of controller wall temperature.
Shown insulation material is to adopt the complex silicate salt material to make, and thermal conductivity factor is about 0.07W/m.K.
Shown inner waterproofing layer and exterior waterproof coating are to adopt the high temperature resistant synthetic plastic of high-quality to make.
The thickness of the external heat preserving device of being made up of magnet, insulation material, inner waterproofing layer and exterior waterproof coating determines that according to Calculation of Heat Transfer generally between 4～15mm, length dimension and width dimensions can decide according to the device diameters size, generally desirable 300～900mm.
The outer heat preservation technology of described magnetic force absorbent-type is mainly used in regenerator, regenerator three-stage cyclone separator or the reactor of petrochemical industry and Coal Chemical Industry industry fluidization reaction-regeneration system, the outer insulation of reactor three-stage cyclone separator housing, is controlled within certain scope with the inside liner of these equipment metal temperature with apparatus casing.When the inside liner of equipment damages and when causing apparatus casing metal overtemperature, this external thermal insulation magnetic force disappears, external thermal insulation comes off automatically, and prompting overtemperature point is avoided the generation of accident.
The present technique main feature has:
1. good heat-insulation effect, the heat-insulation and heat-preservation material thermal conductivity is about 0.07w/m*K, and thermal conductivity factor is basic no change between room temperature to 350 ℃, and outer surface is a pure white, drops to the heat radiation influence minimum;
2. it is simple and convenient to construct, owing to adopted with magnet heat-insulation and heat-preservation material and housing is fixed, and need not weld any insulation supporting construction (circle etc. is supported in bar for line, insulation), need not can finish installation and removal by hand by any specific purpose tool;
3. arbitrarily cutting of heat-insulation and heat-preservation material, assembly unit, thickness can be realized accurate adjustment, for the designer provides well-to-do design space, special-shaped part is easy to realize that the heat-insulation and heat-preservation design combines with liner design and can realize user's maximizing the benefits;
4. safe and reliable, magnet takes off magnetic automatically in 320 ℃ ± 20 ℃ scopes, because the heat-insulation and heat-preservation material has high temperature resistant and high-lubricity, do not have any adhesion when coming off, be specially adapted to lining equipment and pipeline shell in the catalytic cracking unit, and the heat-insulation and heat-preservation material is comparatively frivolous, and any personal accidental injuring event takes place the Shi Buhui that comes off;
5. the skin of heat-insulation and heat-preservation material has good weatherability, so the sleet sky can not influence thermal conductivity factor yet;
6. the scope of application is extensive, because adopting magnetic fixed form realization heat-insulation and heat-preservation material and housing fixes, magnetism intensity can design according to heat-insulation and heat-preservation material thickness, every size, magnetic sheet is arranged and also can be designed as required, the heat-insulation and heat-preservation material has good weatherability, be 20 years projected life, so present technique can be widely used in various large-scale, large equipments such as lining equipment in the refinery catalytic cracking unit and pipeline, various heating furnace and storage tank, spherical tank, coke drum;
The utility model is applicable to that lining equipment and pipeline, the various heating furnace outer wall in outer insulation, the especially refinery catalytic cracking unit of various lining equipments, pipeline all can adopt the present invention.Calculate a cover 100x10 if will adopt the heat energy of being saved behind the present invention to amount to into the diesel combustion value
