The heat insulation structure is characterized in that an enclosed structure is formed around the flanges through inorganic blind hole-type insulation material foam glass; and the enclosed structure is provided with one discharging hole at a low point. The heat insulation structure solves the technical problem of frequent leakage at joints of the flanges of the equipment and pipelines used for conveying or storing the medium containing the ethylene oxide and guarantees easy discovery of leakage points through detection of the low point discharging hole by a detector, thereby preventing fire disasters or other situations caused by leakage.
Description
Technical field
The utility model relates to equipment, the piping flange of engineerings such as being used for chemical industry, petrochemical industry, and particularly a kind of conveying or storage contain the equipment of ethylene oxide (EO) medium, the heat insulating construction at piping flange place.
Background technique
Storage or conveying EO etc. are inflammable, the pipeline and the equipment of explosive medium, and its flange place should be adiabatic, and reason is: 1) for preventing the loss of heat/cold here; When 2) pipeline of EO and equipment met with external flame (external combustion), product can produce decomposition, works the mischief, and need carry out fireproof heat insulating.
Because a variety of causes is carried or storage contains the equipment of EO medium, the flange connections of pipeline leaks easily.If heat insulating construction is not set at flange connections, then can produce owing to amount of localized heat/loss of refrigeration capacity, being scattered fullly in the dielectric leakage place, and reacts with moisture.At this moment, if having some Mars or focus just to be easy to ignite cause danger on every side.If be provided with heat insulating construction, but thermoinsulation material selects to have occurred mistake; At this moment, thermoinsulation material can adsorb the EO material of leakage.Be adsorbed on the EO material in the thermoinsulation material, can produce the possibility of generation of the polyethyleneglycol of low ignition point, assemble spontaneous combustion after a period of time.Particularly, during the EO small leakage, be not easy to be detected, just have potential danger after the consequent residual polyethyleneglycol spontaneous oxidation by gas detecting instrument commonly used.
The model utility content
The purpose of the utility model is to provide a kind of conveying or stores and contains the equipment of EO medium, the heat insulating construction at piping flange place; Mainly solve to carry or store the technical problem that the flange connections of the equipment that contains the EO medium, pipeline leaks easily; In case the leakage of medium takes place in the flange place; Just can also easily find leakage point to the inspection of low spot discharge orifice, with the generation that prevents to cause situation such as fire owing to leaking through detector.
For realizing above-mentioned purpose, the utility model is to realize like this.
A kind of conveying or storage contain the equipment of EO medium, the heat insulating construction at piping flange place, it is characterized in that: around described flange, surround a confined space through inorganic closed cell thermoinsulation material multi cellular glass, this confined space is offered a discharge orifice at low spot.
Described conveying or storage contain the equipment of EO medium, the heat insulating construction at piping flange place, and it is characterized in that: described multi cellular glass is provided with stainless protection layer outward.
Described conveying or storage contain the equipment of EO medium, the heat insulating construction at piping flange place, and it is characterized in that: described flange is connected with pipeline, and the joint of multi cellular glass and pipeline is provided with the stainless steel back-up ring.
Described conveying or storage contain the equipment of EO medium, the heat insulating construction at piping flange place; It is characterized in that: have the valve rod that stretches out multi cellular glass on the described flange, stretch out the multi cellular glass place at valve rod and added an elastic seal ring and seal with elastic sealant.
By said structure, the advantage of the utility model is.
1, the utility model carries out thermal insulation with inorganic closed cell thermoinsulation material-multi cellular glass at the flange place, makes it become a confined space on every side, offers a discharge orifice at low spot; When from material that flange leaks; Make it flow out to collecting tank, thereby can find leakage point fast, help in time taking measures from discharge orifice; Avoid the generation of hazardous accidents, to reach purpose energy-conservation and safety in production.
2, the utility model selects multi cellular glass as thermoinsulation material, and it is because be the closed cell inorganic material, and the EO medium that comes out with leakage chemical reaction can not take place, and can not adsorb the EO medium yet.
3, the utility model structure can realize adorning, tear open rapidly and be convenient.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation.
Fig. 2 is the utility model embodiment 2 a structural representation.
Fig. 3 is the utility model embodiment 3 a structural representation.
Among the figure: 1-thermoinsulation material (multi cellular glass), 2-stainless protection layer, 3-stainless steel back-up ring, 4-elastic seal ring, 5-sealer, 6-Bond, 7-low spot discharge orifice.
Embodiment
See also Fig. 1, it is a kind of structural representation of carrying or storing the heat insulating construction embodiment 1 at the equipment that contains the EO medium, piping flange place of the utility model.As shown in the figure: it is a kind of horizontal pipe flange arrangement, around described flange, surrounds a confined space through inorganic closed cell thermoinsulation material multi cellular glass 1, and this confined space is offered a discharge orifice 7 at low spot.The described multi cellular glass 1 outer stainless protection layer 2 that is provided with.Described flange is connected with pipeline, and multi cellular glass 1 is provided with stainless steel back-up ring 3 with the joint of pipeline.Have the valve rod that stretches out multi cellular glass 1 on the described flange, stretch out the multi cellular glass place at valve rod and added an elastic seal ring 4 and seal, so just can prevent that sealing penetrates into the confined space at flange place with elastic sealant 5.In addition, between the multi cellular glass or the joint between multi cellular glass and the pipeline can select suitable Bond 6 to bond, Bond need satisfied temperature requirement and with the nullvalent requirement of EO medium.
This example is carried out thermal insulation with inorganic closed cell thermoinsulation material-multi cellular glass 1 at the flange place; Make to become a confined space around it, offer a discharge orifice 7, when the material that leaks from flange at low spot; Make it flow out to collecting tank, thereby can find leakage point fast from discharge orifice.Because multi cellular glass is the closed cell inorganic material, chemical reaction can not take place and can not adsorb the EO medium in the EO medium that comes out with leakage.Adopt this structure can realize easy construction, guarantee adiabatic and two purposes of detection with minimum investment.For preventing that leaking medium from flowing into the slit of multi cellular glass and pipeline, in its joint one stainless steel back-up ring 3 is set, it can only be flowed out from discharge orifice 7, thereby can find leakage point fast.Because the linkage structure of detector and discharge orifice is a conventional structure, so repeat no more.
Considering the thermal insulation to EO medium flange place, at first is the assurance of material, and therefore, this example selects multi cellular glass as thermoinsulation material, and it is because be the closed cell inorganic material, and the EO medium that comes out with leakage chemical reaction can not take place, and can not adsorb the EO medium yet.Usually the medium temperature that contains EO is about-30 ℃～+ 300 ℃, so should be incubated and cold insulation according to medium temperature.
In addition, owing to EO can react with carbon steel material, so the material of the metal parts that uses should all be a stainless steel in this example.
See also Fig. 2,3 again, they are respectively the application of heat insulating construction on equipment nozzle flange and vertical tube flange of the utility model, and its agent structure and embodiment's 1 basically identical also have identical technique effect.
