Description

Stove device with liquified petroleum gas bulge and carbon-quinque petroleum mixed as gas

It is the domestic stove device of fuel with the liquefied gas that the utility model belongs to a kind of, particularly a kind ofly mixes with carbon five petroleum hydrocarbons (hereinafter to be referred as C5) and the furnace unit that acts as a fuel with the oil gas bubbling.

Development along with oil exploitation and petro chemical industry, can be more and more for the liquid hydrocarbon that utilizes, with petroleum hydrocarbon cracking system ethene is example, its byproduct C5 accounts for 16.6% of ethylene yield, it is more considerable that casing-head gas separates and separates during stable processing of crude oil the C5 of recovery afterwards, therefore, as combustion gas, increasing research has been carried out at 1967-1992 in countries in the world with C5.C5 is difficult to direct gasification at normal temperatures, and people are once with the pressurization atomizing, and methods such as heating and gasifying act as a fuel after C5 is gasified, but this method needs certain optional equipment, and the danger of blast is arranged, should not be as Domestic stove fuel.Japan this Yu Fu of pine etc. once did domestic fuel research, but used liquefied gas converting means needs the container of anti-certain pressure and temperature, and needed to adopt special catalyst, was difficult to use in general family.Units such as Kingsoft, Shanghai county liquid fuel factory are pressed into air in the steel cylinder that contains C5 with air pump, make the gasification of C5 bubbling, form C5 steam-air Mixture, in the special furnace set internal combustion, though this method is simple, but when C5 fuel reduces, the air that is pressed into might make mixture strength reach explosion ratio scope (LEL is 14.7%, and UEL is 8.3% volume ratio) with regard to the diluted mixture gas-bearing formation, therefore very dangerous, and the residual liquid of this method is more.

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, proposes a kind of safe in utilizationly, reliably, easily, and the gaseous mixture that forms with liquefied petroleum gas bell and C5 is the domestic stove device of fuel.

The utility model furnace unit is made up of oil liquefied gas steel cylinder, C5 steel cylinder, stove and accessory and therebetween connecting line and valve; The outlet of liquefied petroleum steel cylinder is connected with the inlet of tube connector with a path of the bilateral valve that is installed in C5 steel cylinder mouth through pressure-reducing valve, and the other end of this path is equipped with a breather pipe, bottom in the through steel cylinder of this breather pipe, and a porous nozzle is installed in its lower end; Another path of described bilateral valve is that the inner short tube that connects feeds in the steel cylinder on the liquid level, and its outer end joins by tube connector and spark arrester and liquefier stove and accessory.

The utility model stove and accessory is because of having said structure, so it is simple to operate, esy to use, safe and reliable and with low cost, provide a kind of equipment that has practical value for C5 being developed as domestic cooking fuel, not only can effectively utilize and energy savings, reduce atmosphere pollution, and, make things convenient for resident's life to have great importance changing the fuel structure of urban and rural residents, particularly, has the very effect of reality especially to solving the problem of vast rural area fuel famine.

Describe embodiment of the present utility model with reference to the accompanying drawings in detail.

Fig. 1 is the outside drawing of the utility model furnace unit one embodiment.

Fig. 2 is the package assembly schematic diagram of the utility model furnace unit one embodiment.

Fig. 3 is the fuel steel cylinder structural representation of another embodiment of the utility model furnace unit.

Fig. 4 is the A-A generalized section of Fig. 3.

As shown in Figure 1, 2, the utility model furnace unit is made up of liquefied petroleum gas steel cylinder (1), C5 steel cylinder (2), gas stove (3) and valve therebetween and connecting line; Steel cylinder (1) links to each other with a pressure-reducing valve (5) by a single-pass valve (4), this pressure-reducing valve (5) can have self-locking device, just in case when blowby gas path, can cut off source of the gas automatically, pressure-reducing valve (5) outlet is connected to tube connector (6), this tube connector (6) adopts withstand voltage oil resistant flexible pipe, for guaranteeing safety, the safety joint of attaching fast commonly used on the air drill equipment can be equipped with in the termination of tube connector (6), pipeline is installed rapidly, but can not unplug after installing, to guarantee the easy to use and safety of user; The port of export of tube connector (6) links to each other with the inlet of bilateral valve (7) one paths on being installed in C5 steel cylinder (2) bottleneck, this path communicates with being installed in the interior breather pipe (8) that also directly extends its underpart of steel cylinder (2), and this breather pipe (8) lower end is a porous nozzle (9); Another path of described bilateral valve (7), an end join with a short tube (10) in steel cylinder (2), and the port of this short tube (10) is on the C5 liquid level; The other end of this path is on steel cylinder (2) outer connecting pipe road (11); This bilateral valve (7) can open or close the gaseous mixture of liquefied petroleum gas and liquefied petroleum gas and C5 simultaneously; Pipeline (11) joins through spark arrester (12) and gas stove (3).

Another embodiment of the utility model furnace unit, shown in Fig. 3,4, its liquefied petroleum steel cylinder and C5 steel cylinder can close and be made for an integral body, whole steel cylinder is made of inside and outside two cylinders, inner core (15) is the high pressure steel cylinder, urceolus (16) is the normal pressure steel cylinder, and two steel cylinder tops and bottom are respectively the same tube top and the tube end altogether; Inner core (15) is the liquefied petroleum container, and urceolus (16) is the C5 container; Inner core (15) be provided with can and urceolus (16) concentric, also can eccentricly be provided with so that the installation of each valve of steel cylinder top and pipeline, wherein the single-pass valve (4) of liquefied petroleum container top directly connects the breather pipe (8) that has porous nozzle (9) through pressure-reducing valve (5), breather pipe (8) inserts between urceolus (16) and inner core (15) wall, at the bottom of directly stretching into tin; Single-pass valve (7 ') is installed in the C5 container top, and its outlet is connected with liquefied petroleum stove and accessory (2) through spark arrester (12) by pipeline (11).

The method of operating of the utility model furnace unit is very simple, earlier liquefied petroleum steel cylinder one-way valve (4) is opened, and opens C5 steel cylinder bilateral valve (7) then; Check that whether self-locking pressure-reducing valve (5) is in normal working pressure state, if pressure is excessive or too small, can be regulated; Open the switch of stove and accessory (3) at last, promptly incendivity uses, and the raffinate of burning back C5 is few, and the unlikely explosion danger that causes mixed liquid is better than domestic prior art.

Above described C5 be a kind of light petroleum hydrocarbon, it forms complicated, the source difference is the grade difference then, and it is bigger to form difference, and the material of five carbon such as the used C5 isoprene containing of the utility model stove and accessory, 1,3-pentadiene, cyclopentene, pentane is no less than 89 percent.This fuel source is extensive, and the byproduct of all petroleum hydrocarbon cracking ethylene preparations, casing-head gas separate and separate during stable processing of crude oil the C5 that reclaims etc. and all can be used as raw material.
