Description

Pipe conveying system for gasified synthetic fuels at normal atmospheric temperature

The invention belongs to the gas installation field.

Town gas often is rock gas, artificial coal gas and liquefied petroleum gas (LPG) three major types, is gas under its normal temperature and pressure, can directly use for gas range.And synthetic fuel is as the alternative source of the gas of town gas, and its main component is pentane, amylene, and normal temperature and pressure is liquid down, needs to supply gas range to use behind forced gasification.Adopt the gasification installation of synthetic fuel and corollary stove thereof still to be in the development trial period in China at present, in the synthetic fuel gasification installation of having put on market, almost be the microminiature device that single household uses entirely, and really use synthetic fuel, concentrate gasification by gas distribution station, be dispensed to the big-and-middle-sized system of every family with line transportation, Shang Weijian has the report of success.

The objective of the invention is to guide the synthetic fuel gasification technology into extension, scale from small-sized microminiaturization, the centralized pipe conveying system for gasified synthetic fuels at normal atmospheric temperature of the similar liquefied petroleum gas (LPG) gas distribution station of cover effect is provided.The suitable independent use of this system as liquefied synthetic fuels such as C5 fraction, light naphtha, natural gas condensate and LPG (liquefied petroleum gas) residual liquid, or these several liquid fuels use by the proper proportion collocation, except that the preparation of rational proportion on fuel, this system can guarantee round-the-clockly normally to stablize the aerogenesis air feed, satisfies the normal use of system user.

Pipe conveying system for gasified synthetic fuels at normal atmospheric temperature of the present invention mainly is made up of air compressor, ventilation post, balance basin, barometer and various valve, pipe fitting etc.Except that the ventilation post, surplus person all selects general part and standard piece for use.The ventilation post is a key device of the present invention, the present invention adopts the waveform liner plate pillar ventilation post of packing type ventilation gasification mode, pressurized air is agitated synthetic fuel liquid through the radio frequency channel of the numerous intersections of liner plate in the ventilation post, form countless bubbles, under the air-flow effect, the brownian movement aggravation, enthalpy increases, quicken volatilization, promptly form synthetic fuel steam and Air mixing gas, realize the normal temperature gasification of synthetic fuel.This ventilation post is owing to adopt packing type ventilation gasification mode, compares with " Venturi tube " or " perforated tube " of the employing drainage type forced gasification of the similar effect of liquefied petroleum, do not need bigger pressure difference during work, do not produce noise, last work is steady, is convenient to control and efficient height.

Advantage of the present invention comes into plain view, both can solve no artificial coal gas, the town dweller's of rock gas and liquefied petroleum gas (LPG) combustion gas problem, it is again inexpensive synthetic liquid fuel, rank among cities and towns coal gas gas source reliable guarantee is provided, have the gasification of concentrating simultaneously, the networking scale is flexible, little investment, advantages such as safety easy to use.

Now the present invention is described in more detail in conjunction with Figure of description.

Fig. 1 is that system of the present invention constitutes schematic representation.

Fig. 2 is the structural representation of ventilation post.

Fig. 3 is the A-A sectional drawing of ventilation post.

The present invention is by air compressor (1), reduction valve (2), air duct (3), ball valve (4), (9), (10), (13), safety check (5), ventilation post (6), liquid level glass-tube (7), gas phase pipe (8), liquid-phase tube (11), (14), balance basin (12), pressure gauge (15), fuel tube (16), safety valve (17), material feeding mouth union (18), gate valve compositions such as (19), wherein air compressor (1) is connected with damping for rubber hose with reduction valve (2), reduction valve (2) is wire connection with air duct (3), pressure gauge (15), safety valve (17) is wire connection with balance basin (12), and all the other are all flange plate and connect.Ventilation columniation structure such as Fig. 2, shown in Figure 3 are made up of post lid (20), shaft (21), waveform liner plate (22), feed liquor neck (23), fluid neck (24), dividing plate (25), post leg (26), air inlet neck (27), the neck of giving vent to anger (28), needle value (29), (30), liquid level glass-tube (7).Waveform liner plate (22) is divided into three groups of upper, middle and lower, and every group is formed by stacking by tens of corrugated tiles.Every group of corrugated tile is rolled into wave height 10mm with iron sheet, and wavelength mm is tailored into high 100mm then, the rectangular sheet that wide 200--500mm does not wait, its waveform direction and rectangle sideline are 45 ° of inclination angles, and be opposite by adjacent two waveform directions then, and the two narrow modes in the wide outside of middle sheet are formed by stacking.Three groups of waveform liner plates (22) are by upper, middle and lower and be 90 ° of angles mutually and intersect and be positioned on the dividing plate (25).Dividing plate (25) is made the garden plate of ∮ 490mm with steel plate, presses the 40mm spacing on it and bores ∮ 20mm through hole.After dividing plate (25), waveform liner plate (22) order put into shaft (21), pad was gone up the oil resisting paronite pad between post lid (20) and the shaft (21), becomes integral body with bolton.

Open each ball valve and needle value, will synthesize class I liquid I fuel in balance basin (12) and ventilation post (6) are injected in material feeding mouth union (18), it is comparatively suitable with the 1/2--3/4 of tank body height to observe liquid level from liquid level glass-tube (7).Start air compressor (1) and make pressurized air enter ventilation post (6), quicken fluid molecule strenuous exercise, volatilization produces synthetic fuel steam and Air mixing gas, discharges storage from ventilation post (6) top and goes into balance basin (12) first half.Mixed gas is carried through the outside line pipe network with full synthetic steam and Air mixing gaseity at last and is dispensed to the user after balance basin Inner looses foam-expelling.The outside line pipeline is general with conventional town gas pipeline.

For guaranteeing that this system normally moves, the pressurized air that air compressor produces is 0.5MPa, must be decompressed to 0.2MPa through reduction valve and just enter the ventilation post, there is the pressure gradient about 0.3MPa therebetween, to guarantee the buffer action of reduction valve, prevent that operate miss from causing that synthetic fuel liquid oozes the press that makes the return trip empty and forms the detonation accident.For guaranteeing that being responsible for interior combustion gas carries smoothly, system's major network discharge pressure is 0.2MPa, needs to reduce to about 5KPa through pressure governor between major network and user, could supply the user normally to use.The control of native system gas concentration in service is by the suction tude ball valve (4) and liquid inlet pipe ball valve (10) the combination realization of ventilation post; Inlet open is big, and the feed liquor valve turns down, and gasification rate is fast, and synthetic fuel steam ratio is little in the mixed gas; Otherwise gasification rate is slow, and the synthetic fuel vapour concentration is big in the mixed gas, generally controls synthetic fuel steam: air be about 1: 5 more suitable, this moment, the mixed gas Lower heat value made was between 3500--5000 kilocalorie/cubic meter.The present invention is easy to normalization, the scale flexible configuration, generally with aerogenesis unit of a ventilation post and balance basin composition, each in unit year aerogenesis ability 30 ten thousand steres, can use for 500 families.How much press the user, can the combination in parallel of a plurality of unit.
