Abstract
The utility model relates to dimethyl ether mixed natural gas supply equipment which mixes the dimethyl ether with the natural gas as a fuel gas resource for city gas supply and is added based on the original natural gas storage and distribution station. The gas supply equipment of the utility model which comprises a mixer and a vaporizer vaporizes the dimethyl and mixes the dimethyl with natural gas the pressure of which is adjusted in the natural gas storage and distribution station and then sends the mixed gas to the city gas supply network, which guarantees the normal fuel gas consumption of users and relieves the shortages of natural gas supply.
Description
Affiliated technical field:
The utility model is a kind of city gas air feed equipment of dimethyl ether blending rock gas.
Background technique:
At present, because the LPG import price is surging, supply falls short of demand for rock gas, and in the long run, expects that Chinese domestic rock gas is still that supply falls short of demand.The existing energy resource structure of China has the characteristics of few oil, lean gas, many coals, therefore utilizes the dimethyl ether of coal chemical technology production, and can the air feed equipment of blending rock gas alleviate the contradiction of natural gas supply source of the gas anxiety as the alternative source of the gas of gas.Therefore, we have carried out research, solution to the feasibility of this supply technology, the applicability of equipment and the interchangeability of gas equipment etc.
Summary of the invention:
At present, under the natural air-air source situation at full stretch, be to guarantee user's gas just commonly used, improve people's living standard, alleviate the contradiction of natural gas supply source of the gas anxiety, utilize dimethyl ether blending rock gas to replace natural air-air source, as the alternative source of the gas of gas and determining of corollary equipment thereof.
The supply technology of dimethyl ether blending rock gas is feasible, and gas equipment water heater and eyes kitchen range combustion case are all normal, and CO content in smoke has good interchangeability with rock gas below 100ppm.Proportion expression mixer in the air feed equipment mixes the gas scope and mixes the gas precision in 10%-90% in 10%.
The technological scheme that its technical problem that solves the utility model adopts is: utilize blending equipment that dimethyl ether and rock gas are mixed, become a kind of air feed equipment of gas.This equipment mainly is made up of mixer, vaporizer, pressure governor, control system and pipeline, and vaporizer, pressure governor, mixer connect by pipeline, and mixer is connected with gas transmission pipeline net work by pipeline.The dimethyl ether source of the gas is divided into gas phase and two pipelines of liquid phase, and the gas phase pipeline is after relying on dimethyl ether in the dimethyl ether tank car to gasify naturally, through behind flowmeter, the pressure governor with through measure, rock gas after the pressure regulation mixes in mixer.Flowmeter can be selected to install or do not install according to on-the-spot needs, as not installing, then by the mixer control flow rate.Liquid phase pipeline, the liquid phase dimethyl ether is transported to the forced gasification device through the dimethyl ether pump, the dimethyl ether after the gasification is connected to pressure governor by pipeline, through after metering mechanism and the secondary pressure regulation with metering, pressure regulation after rock gas in mixer, mix.The dimethyl ether pump can be selected to install or do not install according to on-the-spot needs, as not installing, then relies on the pressure of dimethyl ether self and gravity that dimethyl ether is transported in the forced gasification device.On-the-spot automatic control equipment is gathered pipeline, device data is taked temperature and pressure signal a little, carries out related valve control by temperature and pressure.
The beneficial effects of the utility model are to improve China's energy resource structure, the contradiction of alleviation natural air-air source anxiety, assurance user gas just commonly used; Mixer can be regulated the mixed proportion of dimethyl ether and rock gas arbitrarily according to the operating mode needs; Dimethyl ether is provided with gas-liquid phase pipeline, can reduce energy consumption, simplify the operation, reduces security risk.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a main technique flow chart of the present utility model.

Embodiment:
1, equipment is installed
According to actual conditions in the rock gas storage and distribution station, for reducing the number of times and getting angry the time of getting angry in the station, newly added equipment adopts the skid mode, outer at the station mixer, vaporizer etc. is fitted together, and carries out pipe arrangement and connect, and integral hoisting is to the scene then.
2, air tightness test
After equipment install to finish, adopt nitrogen that pipeline is purged, purge segmentation and carry out, and equipment such as flowmeter, pressure governor, filter and pipeline are separated, purge, interior welding slag of pipeline and iron rust are removed totally substantially.Purge back pipeline pressurize, and carry out air tightness test according to the air tightness test scheme, with the soap solution test, air tight is qualified.
3, operating procedure
Preparatory work is connected the vaporizer power supply water temperature is heated, and whether the test temp controller proper functioning.
Slowly open tank car liquid phase outlet ball valve, open liquid phase flexible pipe ball valve, stabilized pressure pump bypass tube ball valve successively after confirming to have liquid to flow out,, open exhaust stack valve behind the mixer simultaneously, the nitrogen in equipment and the pipeline is discharged to the vaporizer fluid injection.
Open the gas pipeline valve, close exhaust stack valve behind the mixer, open mixer after ball valve supply gas to pipe network.
Claims (3)
1. the air feed equipment of dimethyl ether blending rock gas, be to utilize blending equipment that dimethyl ether and rock gas are mixed, become a kind of air feed equipment of gas, it is characterized in that: mainly be assembled into a cover blending device systems by mixer, vaporizer, pressure governor, control system and pipeline fittings, vaporizer, pressure governor, mixer connect by pipeline, and mixer is connected with gas transmission pipeline net work by pipeline.
2. the air feed equipment of dimethyl ether blending rock gas according to claim 1 is characterized in that: rock gas and dimethyl ether pipeline are set respectively, and rock gas is connected with pressure governor, mixer respectively with the dimethyl ether pipeline; Be connected with gas phase and liquid phase pipeline on the dimethyl ether pipeline, gas phase pipe and liquid-phase tube be mounted valve all; Rock gas and dimethyl ether pipeline can be equipped with the flowmeter measuring device, and the dimethyl ether liquid-phase tube can be equipped with the dimethyl ether pump.
