The liquid mixing gasifying device of lighter hydrocarbons

It is that main liquid light hydrocarbon (adding a small amount of liquefied gas) is produced air mixture with chemical by-product (carbon five) that the utility model relates to a kind of, directly flows to the liquid mixing gasifying device of lighter hydrocarbons of user's burning with pipeline with low pressure.

The gasification installation that uses has following two kinds at present: a kind of is that light-hydrocarbon gas gasification installation, this device are made of oil storage tank, reactor, combustion gas and air blending tank, air cushioning jar, electric heating water tank, air boost pump, the a small amount of crude oil of input is to reactor from oil storage tank, crude oil is through heat cycles water in the reactor, make crude oil oil temperature rise to 30～40 ℃ and gasify, air boost pump injects the air of air cushioning jar and reactor gasification burning and is transported to combustion gas and air blending tank respectively and forms and mix empty combustion gas and flow to the user by pipeline.Another kind is a Chinese patent, the patent No. is 94200723.9, Granted publication number is CN2185266Y, denomination of invention " light-hydrocarbon gas system supply equipment and pipeline ", the scheme of this patent is: the air supply pipe of light-hydrocarbon gas system supply equipment and oil return pipe communicate with fuel and vapor separator, in user mode, pressure-reducing valve is contained in roof, between fuel and vapor separator and pressure-reducing valve tracheae is housed, between pressure-reducing valve and oil return separator tracheae is housed, between oil return separator and oil storage tank oil pipe is housed, oily vapour separate measurement table and air inlet pipe and flowline communicate with tracheae, and escape pipe communicates with kitchen range.Air inlet pipe is contained between oil tank booster pump and the head tank, magnetic valve is housed on it, fuel feed pump is contained between head tank and the retort, on the water tank of retort electric heater is housed, air hose is contained between gas bag and the retort, magnetic valve is housed on it, the combustion gas booster pump is housed on the gas bag, the air supply pipe of retort communicates with light-hydrocarbon gas system supply equipment and air supply pipe, the oil return pipe of oil storage tank communicates with the oil return pipe of light-hydrocarbon gas system supply equipment, rupture pressure disc also is housed on head tank, rupture pressure disc is housed on the retort, rupture pressure disc is housed on the oil storage tank.Booster pump injects the air of air cushioning jar and sends into retort through the air isocon, in retort, form a large amount of little gas columns and fully mix the formation air mixture with the oil that injects retort, utilize hot water in the electrical heating cyclic water tank simultaneously, thereby the oil temperature in the raising retort, improve gasification result, make air mixture and be transported to the user by pipeline.Above-mentioned two kinds mainly exist following problem: 1, the fluctuation of fuel gas buring calorific value is big, because the lighter hydrocarbons liquid material is with seasonal variations, the crude oil rate of gasification increases with increase in temperature, output gas concentration fluctuating range is bigger, the fluctuation of concentration amplitude surpasses 3%, the fuel gases calorific value fluctuation surpasses 20% (promptly 500 kilocalories), and this brings certain difficulty to correct charge of resident and burning.2, the air feed number of users is restricted.General 3m ³Reactor can only be concentrated with the gas time (date for dinner in two-day weekend) for 200-250 family, particularly user, and system tolerance does not catch up with, and combustion heat value is on the low side, will supply 300-350 family or more families as a supply station, and a reactor does not satisfy.3, winter, outside air temperature was down to zero following, combustion gas is prone to liquid in the pipeline, general light-hydrocarbon gas gasification installation mixes empty than being controlled at 1: 4, the combustion gas dew point is 0～-3 ℃, but winter, outdoor temperature dropped to subzero 5 ℃ or when lower, indoor kitchen space temperature can drop to about 0 ℃, and combustion gas becomes liquid easily in the pipeline, and it will influence resident's burning or see the plug kitchen range.4, oil storage tank lacks light hydrocarbon oil and does not in time transport to, and influences the user and uses gas.

The purpose of this utility model has provided a kind of lighter hydrocarbons mixing gasifying device, the liquefaction tracheae is housed on reactor, be suitable for multiple occasion and use (scarce lighter hydrocarbons fluid oil, replace energy air feed equally with liquefied gas), increased gas gasification efficient and air feed efficient, make combustion gas and air mixing ratio less than 3%, combustion heat value control is below 10%, the combustion gas dew point drops to-7～-10 ℃, and is simple in structure, safe and reliable.

For realizing above-mentioned task, the utility model is by the following technical solutions: it is by oil storage tank, reactor, solar energy cyclic water tank, magnetic valve, air cleaner, air cushioning jar, formation such as Gas Pipe, ball valve, fuel feed pump is housed above oil storage tank, fuel feed pump connects ball valve and links to each other with reactor, reactor both sides water pipe links to each other with the solar energy cyclic water tank, and reactor one side-lower is equipped with air hose and links to each other with air cleaner through magnetic valve.It is characterized in that being equipped with the liquefaction tracheae and link to each other with attenuator, gas meter, flow meter, ball valve, cylinder for liquefied gas above reactor, the reactor top links to each other with user's kitchen range by Gas Pipe, ball valve, gas concentration degree meter.Reactor one side top air hose, attenuator, airflow meter link to each other with air cleaner.The air cushioning jar links to each other with air cleaner by air hose, and the air cushioning jar links to each other with micro-compressor by air hose.
