Description
Technical field
The utility model relates to a kind of gas energy equipment, and more particularly, the utility model relates to a kind of light-hydrocarbon gas equipment.
Background technology
Liquid light hydrocarbon (referring to that mainly carbon number is carbon five, carbon six and the lighter hydrocarbons of minority carbon more than seven) is the accompaniment in oil exploitation, refining, the natural gas purification process.In order to instruct from the perspective of policy and the comprehensive utilization that promotes for this part resource, relevant ministries, commissions and bureaus of country are listed it in " resource comprehensive use catalogue ", and crossed to whole society's publicity and utilized the correlation technique data of this part resource manufacturer with combustion gas, so that this part energy is brought into play maximum economic benefits, social benefit, environmental benefit.For this reason, in nearly two ten years, more domestic enterprises correlation technique that released one after another has successively been built more than 200 air supply system, is mainly used in cooking, dining room gas for cooking, bathing usefulness gas, and back yard industry stove cellar for storing things usefulness gas, boiler usefulness gas, direct combustion machine usefulness gas or the like of residential building sub-district.
In this regard, the Chinese patent file that have that application number is 97109156.0, name is called " carrier gas evaporation pentane pipeline gas conveyer " discloses a kind of gas-carrying evaporation pentane pipeline delivery of fuel gas generating means, and it is made up of control temperature, pressure, automatic control of liquid level circuit, air compressor, air transformer, surge tank, oil storage tank, vacuum tank, combustion gas pressure regulating box and antiriot device.It is said: the temperature of the thermal liquid medium that this technology utilization control specific heat is bigger is controlled the oil temperature indirectly; Utilize the evaporating pressure of the dual control oil of Pressure gauge on air transformer and the surge tank; Utilize vacuum tank and combustion gas pressure regulating box control gaseous-pressure, thereby stablize gas concentration, safe and reliable.Anti-static device, fireproof tempering device further guarantee safety.
It is the effect pentane pipeline gasifier section identical with piped gas of raw material with pentane (C5) that the Chinese patent file that also have that application number is 92209122.6, name is called " civilian pentane pipeline gasifier section " discloses a kind of.It measures sensing head 10 by fuel storage tank 5, air compressor 1, combustable gas concentration and density control valve 9, heater 6 and temperature control element 7, electric cabinet 15, gas pressure regulating box 11 gentle sports associations take over 4,8 and form.Wherein fuel storage tank 5 is airtight non-pressure vessel, built-in liquid pentane (C5), and being provided with heater 6, the pentane of gasification flows to the user through pipeline 20 after entering pressure regulator 11 pressure regulation by outlet, gas connecting tube 8 and the gas concentration control valve that is arranged in storage tank 5 tops again.
But, up to now, because in such technology, traditional system gas device structure imperfection; Critical component (as safety bubbler etc.) parameter, unreasonable structure; Safety devices (as catching the mist device) are not in place; Production procedure imperfection a series of reasons such as (all being one-level system gas basically) cause this technology to have the following disadvantages:
1) weight metal of production unit gas quantity equipment needed thereby is too big, and the efficient that combustion gas is produced is low;
2) the combustion gas poor quality of output: combustion gas unit's calorific value is low, and the fuel gases calorific value fluctuation range of output is big, is difficult to use on the gas equipment little in calorific value requirement variation, that variations in temperature is little;
3) gaseous-pressure of output is low but the pressure oscillation scope is big, thereby has limited follow-up transmission ﹠ distribution distance and the occupation mode of combustion gas, has also limited the production scale of single device;
4) in the larger field, can only adopt the patterns of the most amounts of little unit at a gas consumption with gas, both increase management cost, increase construction cost again;
