Abstract
A paraffin wax transporting pipeline comprises a safety valve, a disconnecting valve and a guide valve; a large-diameter pipe of the pipeline is provided with the safety valve; a small-diameter pipe of the pipeline is provided with the disconnecting valve; a switch of the disconnecting valve is controlled by the guide valve; a front end of the safety valve is provided with an air guide pipe which can enable air to pass through; the external side of the pipeline is provided with a heat preservation layer and a thermal insulation layer; the heat preservation layer is made of polyisocyanurate; the thermal insulation layer is made of flame retardant mastic. According to the paraffin wax transporting pipeline which has functions of insulating static pressure and reducing dynamic pressure, the thermal insulating layer is good in flame retardant performance and the heat preservation layer guarantees temperature of the paraffin wax which is transported inside the pipeline not reducing and guarantees the paraffin wax flowing in a liquid state.
Description
Technical field
The present invention relates to fluid wax transportation technology field, particularly paraffin conveyance conduit.
Background technique
Fluid wax is the mixture of the colorless and odorless that obtains from crude oil fractionation.Water insoluble, glycerine, cold ethanol.Be dissolved in benzene, ether, chloroform, carbon sulfide, hot ethanol.Can mix arbitrarily with most of fat oils except castor oil, camphor, menthol and most of natural or artificial mediocre perfume (or spice) all can be dissolved.Fluid wax often uses as a kind of chemical industry additive, adding while use in most cases needs to use the liquid condition of paraffin to add, because the setting temperature of paraffin is higher, fusing point is lower, therefore, paraffin is generally carried in pipeline with liquid form in production, course of working, in technological operation, also need to maintain the liquid condition of paraffin, but under prior art, paraffin feedway is often inhomogeneous owing to being incubated bad, the interior pressure-controlled of insulation effect, so that affect explained hereafter, even cause serious consequence.
Summary of the invention
Of the present invention in order to solve the adiabatic bad and unbalanced problem of interior pressure-controlled of existing pipeline heat insulation, paraffin conveyance conduit is provided, comprise safety valve, shut off valve and pilot valve, described pipeline large-diameter pipe is established safety valve, the small-bore pipe of described pipeline arranges shut off valve, and described shut off valve is by pilot valve control switch.
The front end of described safety valve is established air pipe that can blowing air.
Thermal insulation layer and thermal-protective coating are established in described pipeline outside.
Described thermal insulation layer is PIC.
Described thermal-protective coating is flame retardant type matizhi.
Paraffin conveyance conduit of the present invention has every static pressure and the dual functions that falls dynamic pressure simultaneously, and thermal-protective coating has good flame retardant property, and the paraffin temperature that thermal insulation layer has kept pipe interior to carry does not reduce, and guarantees that paraffin keeps liquid and flows.
Accompanying drawing explanation
Accompanying drawing 1 width of the present invention:
Fig. 1 is paraffin conveyance conduit schematic diagram of the present invention.
1 resistance tube in figure, 2 safety valves, 3 shut off valves, 4 pilot valves, 5 air pipes.
Embodiment
Following non-limiting example can make the present invention of those of ordinary skill in the art's comprehend, but does not limit the present invention in any way.
