Abstract
The invention discloses a CO2 (carbon dioxide) buried pipeline structure which comprises an operation outer protection pipe, a heat insulating material, an air layer, an operation steel pipe, air outlets and an air inlet. The operation steel pipe is positioned inside the operation outer protection pipe, the heat insulating material is sleeved outside the operation steel pipe, the air layer is reserved between the heat insulating material and the operation outer protection pipe, the air outlets are respectively fixed at two ends and in the middle of the operation outer protection pipe, and the air inlet is further fixed at one end of the operation outer protection pipe. The CO2 buried pipeline structure has the advantages of low heat loss, energy conservation, improved heat insulation effect, long pipeline service life and lowered cost.
Description
Technical field
The present invention relates to a kind of pipeline configuration, relate in particular to a kind of buried pipe structure.
Background technique
Along with improving constantly of production technology, the structure that people can use in life also can improve thereupon, the existing buried pipe that does not pass through gas treatment, the inside all are air contents, because the thermal conductivity of air itself is higher, so that heat loss is high, relatively waste energy, be incubated low, simultaneously also easily oxide etch of pipeline, reduce the working life of pipeline, operating cost is high.
Summary of the invention
The objective of the invention is to provide a kind of CO
2The buried pipe structure.
According to an aspect of the present invention, provide a kind of CO
2The buried pipe structure, comprise the outer pillar of work, thermal insulating material, air layer, working steel tube, relief opening and gas injection port, working steel tube is built in the outer pillar of work, working steel tube is arranged with thermal insulating material outward, be air layer between thermal insulating material and the outer pillar of work, two ends and the middle part of the outer pillar of work are fixed with respectively relief opening, and an end of the outer pillar of work also is fixed with a gas injection port.
In some embodiments, working steel tube is U-shaped with the outer pillar of work.
In some embodiments, relief opening, gas injection port are communicated with air layer respectively.
In some embodiments, relief opening is three.
A kind of CO of the present invention
2The buried pipe structure has that heat loss is low, an energy saving, heat insulation effect improves, pipeline life prolongs and reduce cost effect.
Description of drawings
Fig. 1 is the CO of an embodiment of the present invention
2The structural representation of buried pipe structure.
Embodiment
As shown in Figure 1, the present invention discloses a kind of CO
2The buried pipe structure, comprise the outer pillar 1 of work, thermal insulating material 2, air layer 3, working steel tube 4, relief opening 5 and gas injection port 6, working steel tube 4 is built in the outer pillar 1 of work, the working steel tube 4 outer thermal insulating materials 2 that are arranged with, be air layer 3 between thermal insulating material 2 and the outer pillar 1 of work, work two ends and the middle part of outer pillar 1 is fixed with respectively relief opening 5, and an end of the outer pillar 1 of working also is fixed with a gas injection port 6.In some embodiments, working steel tube 4 is U-shaped with the outer pillar 1 of work.Relief opening 5, gas injection port 6 are communicated with air layer 3 respectively.Relief opening 5 is three.A kind of CO of the present invention
2The buried pipe structure is injected CO the air layer 3 in the pillar 1 from gas injection port 6 outside work
2, because CO
2The density of density ratio air large, inject so CO
2Will toward the bottom deposition of the outer pillar 1 of work, will CO will be positioned at
2The air of top is extruded, and the relief opening 5 of outer pillar 1 one ends of namely working will be with except CO
2Bas Discharged, also above relief opening 5, increase gas measurement instrument simultaneously, gas detecting instrument is controlled start and close by key switch, startup self-detection by after enter normal working, gas detecting instrument detects the gas in the air layer 3 with fixed frequency, and its concentration value changed into electrical signal, electrical signal is through the amplification of amplification circuit, eliminator carries out filtering, after the conversion of analog to digital conversion circuit, become the digital signal that directly to be processed by microprocessor by original analog amount, after this signal is sent into microprocessor, microprocessor reads the correction parameter among the EEPROM, signal is proofreaied and correct processing with the software aspect such as temperature correction, the digital quantity of input is converted into gas concentration value shows intuitively at liquid crystal display.When gas injection port 6 has CO endlessly
2When being injected in the air layer 3, CO
2 Outer pillar 1 middle part of the work that will arrive, the relief opening 5 at outer pillar 1 middle part of working will be except CO
2Other gases discharge, gas measurement instrument detects the CO at middle part simultaneously
2Concentration value, show which gas componant air layer 3 also contains, last CO
2The other end of the outer pillar 1 of arrival work, the gas measurement instrument of relief opening 5 tops will be to the CO in the air layer 3
2Do last detection, the CO that shows in the liquid crystal display of detector
2The concentration of concentration value in continuous increase, other gas concentrations are in continuous minimizing, wait in the liquid crystal display of detector only to show CO
2Concentration value the time, with regard to throttle down, allow be full of pure CO in the pipeline
2Gas.
A kind of CO of the present invention
2The buried pipe structure increases relief opening 5 and gas injection port 6 at existing buried pipe two ends, also increases gas detecting instrument above relief opening 5 simultaneously, has guaranteed to only have CO in the air layer 3
2Existence.Because gas is in zero degrees celsius, CO
2Thermal conductivity be 0.0137, and the thermal conductivity 0.0233 of air compares and nearly differs half, so its heat loss is low, and then energy saving, plays better heat insulation effect, air layer 3 does not have O simultaneously
2, pipeline can oxidation, has prolonged the life-span of pipeline, has reduced cost, has improved working efficiency, and the reasonable like this existing resource of having used is so that whole operation reaches the effect of better energy-saving and emission-reduction.
