Abstract
The utility model relates to a freeze-proofing device of a gas collection pipeline and belongs to the technical field of a natural gas collection-transportation-distribution engineering. The freeze-proofing device is composed of a pipe section shell, connecting flanges, a blind flange, electrical heating rods and a power supply controller. The first connecting flange and the third connecting flange are welded at the two ends of the pipe section shell respectively. An air inlet pup joint is welded on the pipe wall of the pipe section shell, and the second connecting flange is welded on the air inlet pup joint. Through holes are formed in the blind flange and the electrical heating rods are installed in the through holes of the blind flange. The blind flange is connected with the third connecting flange on the pipe section shell through bolts. By the utilization of electric power heat energy of the electrical heating rods and natural gas media inside a closed pipeline system, heat transfer is directly and safely performed. The electro-thermal transfer efficiency can reach above 95%. The situation that a natural gas collection-transportation system runs safely is guaranteed. Technological facilities are simple, engineering investments are low, and the engineering level of a collection-transportation technology and overall benefits of gas field development are improved.
Description
Technical field
The utility model relates to a kind of collecting pipe defroster, belong to needs intensifications such as well site gas gathering station, the pipeline heating station along the line of gas gathering and transportation distribution field of engineering technology, especially gas field gas gathering system, concentrated gas gathering station, defeated gas distribution station and prevent that hydrate from generating the freezing prevention tubing device.
Background technique
The biggest problem that rock gas runs in producing the gas collection process is because throttling produces " joule-Thompson " temperature drop effect, produces hydrate and forms pipe freezeup, causes the gathering and transportation technology system normally to move.Stifled for preventing that hydrate from freezing, the measure of adopting usually both at home and abroad has the methyl alcohol of notes method, multiple stage water jacket oven temperature-raising method and three kinds of methods of heat tape temperature-raising method.Wherein, annotate the methyl alcohol method and need methyl alcohol injection device and process matched therewith flow process be installed in the gas gathering and transportation system, and the sewage treatment that contains methyl alcohol acquires a certain degree of difficulty, expense is higher.Multiple stage water jacket oven temperature-raising method is the measure that the gas field gas collection technique often adopts, need water batch heater, blowdown system and fuel gas be set in the well site and return defeated pipeline, and the energy consumption height, management difficulty is big.Heat tape temperature-raising method employing ribbon heater is wrapped on the pipeline heats, because utilization rate of electrical is not high, and the general pipeline local heat treatment that only is used for.
The model utility content
The purpose of this utility model is in order to overcome the high defective of complex process, energy consumption that above-mentioned prior art exists, a kind of technologies such as notes methyl alcohol method and multiple stage water jacket heating oven process that are intended to replace are provided, prevent from forming gas hydrates and freeze stifled online collecting pipe defroster.
For addressing the above problem, the technical solution adopted in the utility model is:
A kind of collecting pipe defroster, comprise pipeline section housing, adpting flange, blank flange, electrical heating rod and power-supply controller of electric, pipeline section housing two ends are welded with first adpting flange and the 3rd adpting flange respectively, tube wall at the pipeline section housing is welded with the air inlet pipe nipple, is welded with second adpting flange on the air inlet pipe nipple; Have through hole on the blank flange, in its through hole electrical heating rod is installed, blank flange is connected with the 3rd adpting flange on the pipeline section housing by bolt.
The automatic control probe is installed on the pipeline section housing outer tube wall, and the automatic control probe is connected with power-supply controller of electric by electric wire.
The utility model utilizes electric power heat energy and the direct safe heat transfer of the intrasystem gas medium of closed conduit of electrical heating rod, electric conversion efficiency can reach more than 95%, guarantee the gas gathering and transportation system safety operation, process facility is simple, construction investment is low, has improved gathering and transportation technology technical merit and gas field development overall efficiency.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
As shown in Figure 1, the utility model embodiment comprises pipeline section housing 5, adpting flange, blank flange 7, electrical heating rod 4 and power-supply controller of electric 8 compositions, pipeline section housing 5 two ends are welded with the first adpting flange 3a and the 3rd adpting flange 3c respectively, tube wall at pipeline section housing 5 is welded with air inlet pipe nipple 9, is welded with the second adpting flange 3b on the air inlet pipe nipple 9; Have through hole on the blank flange 7, electrical heating rod 4 is installed in its through hole, blank flange 7 is connected with the 3rd adpting flange 3c on the pipeline section housing 5 by bolt.
By the second adpting flange 3b on the air inlet pipe nipple 9 and the first adpting flange 3a on the pipeline section housing 5 the utility model is installed on the inlet/outlet valve on the collecting pipe, arrow is gas turnover direction among the figure, opening power controller 8 makes electrical heating rod 4 heating, can avoid the formation of gas hydrates in the collecting pipe, it is stifled to prevent that collecting pipe from freezing.
