Integration note alcohol injecting device
Technical field
The present invention relates to gas gathering and transportation field, especially relating to one can simplification of flowsheet, realizes the integration note alcohol injecting device of digitizing sledge dressization.
Background technique
Along with expanding economy, country is increasing to the demand of the energy, and as the rock gas of clean energy resource, development speed is swift and violent.In gas exploitation course, when temperature is lower, natural gas line easily produces ice and blocks up phenomenon, now needs methanol solution to inject tank body or pipeline, thus avoids ice to block up.In addition, corrosion inhibitor injects for preventing H in natural gas compressor station process pipe
2s and CO
2corrode significant, defoamer injects the generation that effectively can prevent deleterious bubbles, ensures the normal operation in whole station district.
At present, general field, station, natural gas collecting station note alcohol injecting is all the size according to field, station, and gas liquid ratio etc. determine scale, field fabrication, build methyl alcohol injected system and injecting modulating system respectively, install and need civil engineering to coordinate, and construction is complicated, and the cycle is longer.
Summary of the invention
Instant invention overcomes above-mentioned shortcoming of the prior art, provide a kind of integration note alcohol injecting device, this device manufactures debugging and completes in factory, and shipping container assembles, and is directly lifted into scene, installs simple.
Integration note alcohol injecting device of the present invention comprises: sledge seat and the corrosion inhibitor storage tank 12 be installed on sledge seat, defoamer storage tank 13, double pump head diaphragm metering pump 1, single pump head diaphragm metering pump 2, plunger type metering pump 3, unload Teat pipette 4 and each connecting line, there is in pipeline the methyl alcohol mouth of pipe, the methyl alcohol entering pipeline divides three tunnel conveyings, the first via is directly measured outside supercharging by described double end diaphragm metering pump 1 and is passed to each well head pipeline, the interior note methyl alcohol interface that arrives at a station is carried by described single pump head diaphragm metering pump 2, second tunnel enters described defoamer storage tank 13 and modulates with defoamer, after modulation, mixed solution is by transporting to well head pipeline outside the supercharging of described double pump head diaphragm metering pump 1, the interior note defoamer interface that arrives at a station is carried by described single pump head diaphragm metering pump 2, 3rd tunnel and defoamer modulate after methyl alcohol pass through described in unload Teat pipette 4 and enter described corrosion inhibitor storage tank 12, external transport pipeline is entered by described single pump head diaphragm metering pump 2.
Compared with prior art, advantage of the present invention is: integration note alcohol injecting device focuses alcohol, note corrosion inhibitor and these three kinds of functions of note defoamer in same skid body, simplify pipeline, make device integral skid mounting, conveniently be applied to natural gas line and divide defeated station preventing freeze in winter, there is the features such as equipment is simple, making and installation cycle antifreezing effect that is short, little to normal influence on system operation, that obtain is better.

Embodiment
A kind of integration note alcohol injecting device, as shown in Figure 1-2, comprising: sledge seat and be installed on corrosion inhibitor storage tank 12, defoamer storage tank 13, double pump head diaphragm metering pump 1, single pump head diaphragm metering pump 2, plunger type metering pump 3 on sledge seat, unload Teat pipette 4 and each connecting line.As described in Figure 1, be connected in a pipeline of defoamer storage tank 12 one end and there is the methyl alcohol mouth of pipe, methyl alcohol from the methanol tank outside sledge enters pipeline system by this mouth of pipe, and be divided into three tunnels and carry, the first via is directly measured outside supercharging by described double end diaphragm metering pump 1 and is passed to each well head pipeline, the interior note methyl alcohol interface that arrives at a station is carried by described single pump head diaphragm metering pump 2, second tunnel enters described defoamer storage tank 13 and modulates with defoamer, after modulation, mixed solution is by transporting to each well head pipeline outside the supercharging of described double pump head diaphragm metering pump 1, the interior note defoamer interface that arrives at a station is carried by described single pump head diaphragm metering pump 2, unload Teat pipette 4 described in 3rd tunnel and defoamer pass through after modulating and enter described corrosion inhibitor storage tank 12, external transport pipeline is entered by described single pump head diaphragm metering pump 2.
As described in Figure 1, although illustrate the single pump head diaphragm metering pump 2 of six double pump head diaphragm metering pumps 1, two and two plunger type metering pumps 3, but the quantity of metering pump is not as limit, well-known to those skilled in the artly be, according to technological process and function requirement, the metering pump of other varying numbers can be set according to overall gas gathering station treating capacity.In addition, each alchol-injection pump is all provided with by-pass line, ensureing that pump can supplement methyl alcohol by timely stand by pump when there being fault, ensureing the fluency of well head.
Described integration note alcohol injecting device comprises the filter 5 being located at described double pump head diaphragm metering pump 1, single pump head diaphragm metering pump 2 and plunger type metering pump 3 front end further, and filtering enters the impurity of metering pump, makes it keep normal operation.
Described integration note alcohol injecting device comprises the gate valve/ball valve 6 being located at described double pump head diaphragm metering pump 1, single pump head diaphragm metering pump 2 and plunger type metering pump 3 front end and/or rear end further, 10,11, gate valve/ball valve 6,11 switch for the flow process of methyl alcohol and defoamer, and gate valve/ball valve 10 plays a part to turn off.
Described integration note alcohol injecting device comprises the safety valve 7 be located on pipeline, pressure gauge 8 and safety check 9 further, safety valve 7 is for ensureing that loine pressure is stablized, having decompression function, pressure gauge 8 is for checking the pressure of pipeline section at that time, and safety check 9 flows backwards for preventing pipeline medium.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious realization of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technological scheme is carried out; or design of the present invention and technological scheme directly applied to other occasion, all in protection scope of the present invention without to improve.
