Abstract
A double metering pump motor-driven prying-arranged alcohol filling device comprises a tank body, a self-priming pump, an anti-explosion electronic control cabinet and a prying-arranged base. The double metering pump motor-driven prying-arranged alcohol filling device is characterized in that the tank body, the self-priming pump, a first metering pump and a second metering pump are fixed on the upper portion of the prying-arranged base. A material adding ball valve and a material adding filter which are installed at the lower portion of the prying-arranged base are connected on an inlet of the self-priming pump through a pipeline. An outlet of the self-priming pump is connected at the upper end of the tank body through a pipeline. The lower end of the tank body is connected with an inlet filter and an inlet tee ball valve which are installed at the lower portion of the prying-arranged base. Two connectors of the inlet tee ball valve are respectively connected on an inlet of the first metering pump and an inlet of the second metering pump. An outlet of the first metering pump and an outlet of the second metering pump are connected on a high-pressure tee through a first high pressure ball valve and a second high pressure ball valve respectively. The high-pressure tee is connected on a filling head through a pipeline. The pipeline is connected with a one-way valve, an energy accumulator, a needle-shaped valve and a stop valve. The pressure relief needle-shaped valve is connected at the upper end of the tank body through a tee. The double metering pump motor-driven prying-arranged alcohol filling device is suitable for filling alcohol to natural gas with flow which is below 120L/h, the alcohol is filled in a natural gas line in a two-metering-pump changing-over mode according to a certain proportion, and the double metering pump motor-driven prying-arranged alcohol filling device is convenient and simple to operate.
Description
Technical field
The utility model relates to a kind of filling methanol device of natural gas line, and is especially a kind of with methyl alcohol medicament adding gas distributing system, makes natural gas line have antifreeze stifled skid and annotates pure filling apparatus.
Background technique
In the defeated process of natural gas tube, because the variation of fluidised form and ambient temperature can produce condensation water more or less, and build up in pipeline.Along with the increase of accumulation, meet pipeline big rise and fall, winter temperature when low, at the low-lying place of pipeline or air communication cross valve, threeway, separator and separate the first-class place that may produce throttle effect and hydrate will occur.Hydrate produces throttle effect in case after forming, can reduce circulation area, quickens the formation of hydrate, thus blocking pipe to cause pipeline to build the pressure accidents caused, take measure such as emptying step-down to resume production during de-plugging simultaneously, also will cause the tolerance loss.
During modern industry was produced, often filling methyl alcohol medicament in natural gas line solved pipeline and freezes stifled problem.Present existing special device only is provided with a metering pump filling methyl alcohol, and be not suitable at continuous filling of separate unit metering pump maintenance period methyl alcohol, therefore demand providing a kind of urgently and be applicable to that the mode of two metering pumps switchings is continual to natural gas line filling methanol device, to satisfy the demand.
Summary of the invention
The purpose of this utility model is to provide a kind of skid to annotate pure filling apparatus in order to solve the problems of the technologies described above, be applicable to the natural gas line filling methyl alcohol of flow below 120L/h, methyl alcohol is joined among the natural gas line with the mode of two metering pumps switchings down according to a certain percentage, easy and simple to handle.
In order to achieve the above object, the technological scheme that the utility model provides is as follows: comprise tank body, self-priming pump, explosion-proof electric control cubicle, skid base, it is characterized in that: tank body, self-priming pump, 1# metering pump, 2# metering pump are fixed on skid base top; What be installed in skid base bottom adds the pellet valve, adding the material filter is connected on the self-priming pump inlet by pipeline, the self-priming pump outlet is connected the tank body upper end by pipeline, the tank body lower end is mounted on the inlet filter and the inlet tee ball valve of skid base bottom, two interfaces of inlet tee ball valve are connected on the inlet of 1# metering pump inlet and 2# metering pump, 1# measures delivery side of pump, 2# metering delivery side of pump is respectively by the 1# high-pressure ball valve, the 2# high-pressure ball valve is connected on the Highpressure Tee, Highpressure Tee is connected on the filling head by pipeline, connect one-way valve on the pipeline, accumulator, needle type valve and stop valve, the release needle type valve is connected the tank body upper end by threeway.
The utility model has the advantages that: be applicable to the rock gas filling methyl alcohol of flow below 120L/h, methyl alcohol is joined among the natural gas line with the mode of two metering pumps switchings down according to a certain percentage, easy and simple to handle.
