Abstract

The utility model relates to an evaporator, which comprises a bottom box and a box cover. A plurality of permeating holes are arranged on the periphery of the bottom box, a soleplate and the box cover. The utility model uses light hydrocarbon as the main fuel instead of diesel in catering industry; light hydrocarbon burns stably and fully without black smoke and odor; the fire can be adjusted conveniently and flexibly. The utility model not only protects the environment but also reduces fuel cost.

Description

Evaporimeter

Technical field

The utility model belongs to fuel oil, particularly replaces diesel oil with lighter hydrocarbons in catering trade is the evaporimeter field of use in fuels.

Background technology

Have in the catering trade at present significant proportion with diesel oil as main fuel.Because the burning condition on the catering trade cooking stove is bad, diesel combustion is incomplete, and black smoke is big during burning, and strange taste is arranged, and often has oil droplet to splash, and has not only wasted resource but also contaminated environment.And diesel oil belongs to strategic materials, and catering trade uses diesel oil to make main raw material, has increased the weight of the burden of this strategic materials of China's import, simultaneously the fuel cost of catering trade can not be fallen.Therefore using the alternative diesel oil of clean energy resource of environment-friendly type has been imperative as catering trade fuel.

In issuing＜the comprehensive utilization of resources catalogue by State Economic and Trade Commission, planning commission, the Ministry of Finance, State Administration of Taxation in November, 1996, lighter hydrocarbons have been included in country and encouraged one of resource kind of development and use.The lighter hydrocarbons performance is the raffinate of liquefied petroleum gas between liquefied petroleum gas and gasoline, is again the gasoline tops, mainly contains C ₅-C ₇, calorific value is about 45900-48400J/kg, and boiling range is between 30-150 ℃, and the market price is lower by about 10% than diesel oil.Can process extraction in the leftover bits and pieces of oilfield exploitation, oil plant, petrochemical plant, ethylene plant etc., be a kind of clean energy resource of high-quality and efficient environment-friendly type.If put into the diesel oil cooking stove that generally uses now and use but directly lighter hydrocarbons are replaced diesel oil, the sometimes prominent height of combustion instability, detonation easily, flame sometimes reduces, and is difficult to control, because effect is undesirable, hindered lighter hydrocarbons and extensively replaced diesel oil and make the catering trade primary raw material.

Summary of the invention

The technical problems to be solved in the utility model is to make the lighter hydrocarbons can smooth combustion, makes that heat energy is more made full use of in the fuel.

The utility model solves the problems of the technologies described above with following technical scheme: evaporimeter is made up of end box and lid, and the periphery of end box, base plate and lid are covered with penetrating aperture.Inner chamber filling heat-storing material, sustained release agent and the catalyst of evaporimeter.

Use evaporimeter of the present utility model; Light hydrocarbon burner is stable, fully, the adjusting of no black smoke, no strange taste, flame size and power is very convenient flexible; both protected environment; greatly reduced the cost of fuel oil again; and can utilize the existing burner that burns diesel oil to change the burning lighter hydrocarbons, create very advantageous conditions to promoting the use of lighter hydrocarbons.

Description of drawings

Fig. 1 is the structural representation of the utility model evaporimeter when placing in the burner of diesel oil cooking stove.

The specific embodiment

Evaporimeter is made up of end box 2 and lid 3, and the base plate of end box, side plate and lid are covered with penetrating aperture all around.The box internal cavity is filled heat-storing material, sustained release agent and catalyst, heat-storing material can be selected bigger material of thermal capacitance such as seat clay etc., sustained release agent can be selected the material such as the calcium chloride that can make liquid light hydrocarbon slowly discharge the gaseous state lighter hydrocarbons reposefully for use, and catalyst can be selected materials such as silica for use.When being used for evaporimeter of the present utility model on the existing food and drink diesel oil cooking stove, need only the burner 4 of evaporimeter being put into diesel oil, lighter hydrocarbons basin and oil-in 1 are connected and can start working with flexible pipe.Because the gasification temperature of lighter hydrocarbons is much lower than diesel oil, promptly have part to begin gasification under the normal temperature, so lighter hydrocarbons need not give heat in burner and gasification just has volatilization, volume became big after liquid light hydrocarbon entered burner in addition, and pressure reduces, and has quickened the gas-liquid separation phenomenon, very easily light quick combustion.Penetrated by the flame width of cloth after heating begins to heat up when the heat-storing material in the evaporator box, the lighter hydrocarbons that enter in the evaporimeter also heat up, and impel its gasification rate to accelerate, and combusting firepower strengthens rapidly, forms benign cycle; Sustained release agent in the evaporimeter can absorb liquid light hydrocarbon earlier, then slowly discharges the gaseous state lighter hydrocarbons more reposefully, makes lighter hydrocarbons can keep burning in a long time; Catalyst can reduce the surface tension of liquid light hydrocarbon, reduces evaporation institute calorific requirement, helps flame to strengthen, and burning fully.During burning, liquid light hydrocarbon enters in the evaporimeter by the penetrating aperture on the evaporator box wall again after entering the burner inner chamber from the oil-in 1 of burner, and the gaseous state lighter hydrocarbons that evaporation the produces penetrating aperture on the box wall again pierce burner and participate in burning.Gaseous state Light hydrocarbon burner required air during still by original burning diesel oil supporting air feed facility supply with, blast after air enters burner interlayer 6 from air inlet 7, enter inner chamber and the mixed combustion of gaseous state lighter hydrocarbons through the aperture in the interlayer 5 again.
