Description
The utility model relates to a kind of direct electric heating lighter hydrocarbons liquid gasification installation.
Here the lighter hydrocarbons liquid of indication mainly is meant based on pentane except that the raffinate of used liquefied petroleum gas, contains the liquid fuel of part hexane, also can abbreviate crude pentane as.They all are by-products of oil refinery.Because the octane value of crude pentane is low, be about 62 and boiling point height (pentane is 36.1 ℃, and hexane is 69 ℃), therefore, it can not can not use as combustible gas for the resident without gasification as the fuel of internal-combustion engine.So annual the overstocking of this lighter hydrocarbons liquid China reaches more than millions of tons.This shows that active development utilizes lighter hydrocarbons liquid that important economic value is arranged.
At present, the many departments of China all at research and utilization lighter hydrocarbons liquid as civilian combustible gas.Up to now, have only two kinds of methods: promptly blow evaporating method and indirect heating evaporating method.
Typical air blowing evaporating method such as Chinese patent 1112214 " gasifying liquefied petroleum gas device ", be characterized in that heated liquefied petroleum letter shoot is located in the heating chamber that has the air supplying tube, heated air delivery pipe is imported hot air by single-phase valve to heated liquefied petroleum tracheae, through gas, liquid in pipe, mix be incorporated in the heating chamber heating after, export combustible gas by mixture pipe and use for the user.This shows, the air blowing evaporating method need be equipped with more equipment and instrument, as instrument such as heating chamber, heater, air-blaster and temperature, pressure and flows, cost is big undoubtedly, power consumption is higher and the thermal efficiency is low, but its topmost problem, be the instantaneous variation that in time to follow user's gas consumption, keep constant temperature, constant voltage gasification.Secondly, the tightness of single-phase valve is difficult to guarantee 100%, so as user during suddenly without gas, produce back-pressure in the pipeline, manages interior mixed gas this moment and might sew to indoor from single-phase valve.Therefore, poor stability.
The indirect heating evaporating method divides by thermal source: two kinds of methods of hot water and electric heating are arranged.Adopt having of hot water heating: Chinese patent 2196729 " synthetic fuel gasification installation ", it comprises body of heater, flue and thermal storage water tank, the synthetic fuel case is placed in the hot water tank gasifies.Chinese patent 2185833 " liquefied gas residue heat catalysis basin " and for example, it is that steel cylinder with the contain liquefied gas residue is placed in the hot water basin, shape at the bottom of the hot water basin is made and the corresponding annular recess of steel cylinder base shape, the water-injecting cavity at basin top is gone into hot water from the basin rising pouring, one upper lateral part of basin has flow-off, hot water is from making progress at the bottom of the basin to the flow-off outflow, to reach the purpose of heating steel cylinder.Chinese patent 2084548 " cylinder for liquefied gas heating warmer ", its principle and structure are also with above-mentioned similar substantially.The characteristics of Chinese patent 2142922 " LPG (liquefied petroleum gas) residual liquid gasification utilized device " are to use now a catheter is installed on the angle valve endoporus of steel cylinder, raffinate in the bottle is pressed into the vaporizer that has hot water jacket's (or adding heat medium electricity consumption heater heats again in the chuck) gasifies.
