Abstract
The invention discloses an urban gas supply device. The urban gas supply device is characterized in that a mixing device system is formed by mainly assembling a mixer, a gasification device, a pressure regulator, a control system and pipeline accessories; the gasification device, the pressure regulator and the mixer are connected through a pipeline; a proportional flow regulator is arranged on the mixer; the mixer is connected with a gas supply pipe network through a pipeline and provided with a natural gas pipeline and a dimethyl ether pipeline; the natural gas pipe and the dimethyl ether pipeline are both connected with the pressure regulator and the mixer; a gas-phase pipeline and a liquid-phase pipeline are connected to the dimethyl ether pipeline; valves are installed on the gas-phase pipeline and the liquid-phase pipeline respectively; flow meters can be arranged on the natural gas pipeline and the dimethyl ether pipeline; and dimethyl ether pumps can be arranged on the dimethyl ether liquid-phase pipe. By means of the urban gas supply device, the energy structure of China can be improved, the contradiction of natural gas source shortage is relieved, and normal gas consumption is ensured for users; and the gas-phase pipeline and the liquid-phase pipeline are arranged for dimethyl ether, energy consumption can be lowered, operation can be simplified, and safety risks are reduced.
Description
Technical field
The present invention relates to a kind of city gas air feed equipment.
Background technique
At present, because import price is surging, supply falls short of demand for rock gas, and in the long run, and expection China rock gas is still that supply falls short of demand.Can the existing energy resource structure of China has the feature of few oil, lean gas, many coals, therefore utilizes the dimethyl ether that coal chemical technology is produced, the air feed equipment of blending rock gas, as the alternative source of the gas of gas, alleviate the contradiction of natural gas supply source of the gas anxiety.Therefore, we are studied the interchangeability etc. of the feasibility of this supply technology, the applicability of equipment and gas equipment, solve.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the city gas air feed equipment providing a kind of practicality, when natural air-air source is at full stretch, the just conventional gas of user can be ensured, improve the living standard of people, alleviating the contradiction of natural gas supply source of the gas anxiety, replacing natural air-air source, as the alternative source of the gas of gas and the determination of corollary equipment thereof utilizing dimethyl ether blending rock gas.
For reaching above-described object, a kind of city gas air feed equipment of the present invention takes following technological scheme:
A kind of city gas air feed equipment, it is characterized in that, a set of blending device systems is assembled into primarily of mixer, vaporizer, pressure governor, control system and pipeline fittings, vaporizer, pressure governor, mixer are connected by pipeline, proportion of installation formula flow regulator on described mixer, mixer is connected with gas transmission pipeline net work by pipeline, and arrange rock gas and dimethyl ether pipeline respectively, rock gas is connected with pressure governor, mixer respectively with dimethyl ether pipeline; Dimethyl ether pipeline is connected with gas phase and liquid phase pipeline, gas phase pipe and liquid-phase tube all mounted valves; Rock gas and dimethyl ether pipeline can be equipped with flow gauge, and dimethyl ether liquid-phase tube can be equipped with dimethyl ether pump.
Adopt the present invention of as above technological scheme, there is following beneficial effect:
Improve China's energy resource structure, alleviate the contradiction of natural air-air source anxiety, ensure the just conventional gas of user; Mixer according to operating mode needs, can regulate arbitrarily the mixed proportion of dimethyl ether and rock gas; Dimethyl ether arranges liquid phase pipeline, can reduce energy consumption, simplifies the operation, reduce security risk.
Accompanying drawing explanation
Fig. 1 is technical process figure of the present invention.
In figure: 1. dimethyl ether tank car, 2. dimethyl ether liquid pipe, 3. dimethyl ether gas phase pipeline, 4. dimethyl ether pump, 5. vaporizer, 6. pressure governor, 7. pressure, temperature signal collection control point, 8. flowmeter, 9. mixer, 10. dimethyl ether and rock gas mixed gas pipeline, 11. natural gas lines, 12. rock gas station systems, 13. connect city gas pipeline.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of city gas air feed equipment of the present invention, the supply technology of dimethyl ether blending rock gas is feasible, and gas equipment water heater and eyes stove combustion case are all normal, and CO content in smoke, at below 100ppm, has good interchangeability with rock gas.Proportional mixer in air feed equipment mixes gas scope and in 10%-90%, mixes gas precision within 10%.
1, equipment is installed
According to actual conditions in natural gas distribution station, for reducing in station the number of times and getting angry the time of getting angry, newly added equipment adopts skid mode, mixer, vaporizer etc. is fitted together outward at station, and carries out pipe arrangement connection, and then integral hoisting is to on-the-spot.
2, air tightness test
After equipment is installed and terminated, Bian nitrogen purges pipeline, and purge segmentation and carry out, and the equipment such as flowmeter, pressure governor, filter and pipeline are separated, purge, in pipeline, welding slag and iron rust are removed totally substantially.Pipeline pressurize after purging, and carry out air tightness test according to air tightness test scheme, with soap solution test, air tight is qualified.
3, operating procedure
Preparatory work, connects vaporizer power supply by water temp. heating, and whether test temp controller normally works.Slow unlatching tank car liquid-phase outlet ball valve, opens liquid phase flexible pipe ball valve, stabilized pressure pump bypass tube ball valve after confirming have liquid to flow out successively, and to vaporizer fluid injection, simultaneously Jian opens exhaust stack valve after mixer, is discharged by the nitrogen in equipment and pipeline.Open gas pipeline valve, exhaust stack valve after closedown mixer, after opening mixer, ball valve is supplied gas to pipe network.
