Description

A method of supply hot oil, hot water

Technical field

The present invention relates to a kind of methods using multifunctional heating device heat supply, and relating more specifically to one kind can supply simultaneously The method for answering hot oil, hot water.

Background technique

Boiler is the mechanical equipment for water being heated as using the thermal energy of fuel or other energy hot water or steam.In boiler The hot water or steam of generation directly can provide required thermal energy for industrial production and people's lives, can also be filled by steam power It sets and is converted to mechanical energy, or electric energy is converted mechanical energy by generator again.The boiler for providing hot water is known as hot-water boiler, main It is used to live, also there is a small amount of application in industrial production.The boiler for generating steam is known as steam boiler, is chiefly used in thermal power station, ship Oceangoing ship, locomotive and industrial and mining enterprises.

It is well known that boiling point is 100 DEG C to water under normal pressure, when external pressure increases, the boiling point of water increases therewith, therefore, In order to meet the needs of industrial production and people's lives, boiler usually all passes through setting pressure vessel (drum/drum) Lai Zengjia Pressure is higher than 100 DEG C of hot water or steam to obtain.Boilers and pressure vessel volume is big, sealing, bear high pressure etc. due to, hold Easily occur leakage, explosion accident and jeopardize the safety of personnel, equipment and property.

In addition, there are also a kind of boilers using heat-conducting oil heating heat conducting oil boiler.Conduction oil, also known as organic heat carrier, Thermal medium oil, hot oil, liquid energe-carrying medium, heat transfer oil are substantially a kind of high boiling liquids, are GB/T 4016-1983 The former name of " heat medium oil " in " oil product vocabulary of terms ", English name are Heat transfer oil, for passing indirectly Pass the specialized oil product of a kind of better heat stability of heat.Since it is with homogeneous heating, temperature adjustment precise control can be in low steam The features such as pressure generates high temperature, and heat-transfer effect is good, energy conservation, conveys and is easy to operate, is widely used in various occasions in recent years, and And its purposes and dosage are more and more.

Conduction oil is mainly the following type in the prior art:

1) alkyl benzene-type (benzenoid form) conduction oil: this kind of conduction oils are the chemical combination that phenyl ring has alkane branching types Object belongs to product of the short-chain branch alkyl (including methyl, ethyl, isopropyl) in conjunction with phenyl ring.Its boiling point at 170~180 DEG C, Condensation point is at -80 DEG C or less.

2) alkylnaphthalene type conduction oil: the structure of this type conduction oil is the compound that alkane branch is connected on phenyl ring.It Attached side chain generally has methyl, dimethyl, isopropyl etc., and the type and quantity of adding side chain determine the property of compound Matter.The connected alkylnaphthalene of side chain chief of the Xiongnu in Acient China's methyl, the vapour phase heating system applied to 240~280 DEG C of ranges.

3) alkyl biphenyl type conduction oil: the conduction oil of this type is the chemical combination that alkyl branches one kind is connected on biphenyl basic ring Object.Its boiling point > 330 DEG C, thermal stability is also good, is the ideal product used within the scope of 300~340 DEG C.

4) biphenyl and Biphenyl Ether eutectic mixture type conduction oil: the conduction oil of this type is that biphenyl and Biphenyl Ether eutectic are mixed Object is closed to be made of 26.5% biphenyl and 73.5% Biphenyl Ether.Fusing point is 12 DEG C, and the synthesis aromatic hydrocarbons used earliest in the world is led Hot oil is Dowtherm, its main feature is that thermal stability is good, it is high (400 DEG C) using temperature.Such product because phenyl ring on not with The connection of alkane base side chain, and heat resistance is best in organic heat carrier.This condensation point (12.3 DEG C) eutectic mixture, in room temperature Under, boiling temperature is within the scope of 256~258 DEG C using both economical.

5) alkyl biphenyl ether type conduction oil: for an ethers link among two phenyl ring, on two phenyl ring respectively there are two The admixture of isomeric compound of methyl, kinematic viscosity is low under such mixing conduction oil low temperature, good fluidity, is suitble to the cold ground in the north Area uses, it is recommended to use not more than 330 DEG C of temperature, -54 DEG C of condensation point.

When production environment had not only needed using hot-water boiler but also needed to use heat conducting oil boiler, user needs while buying This two classes boiler, causes use cost to be significantly increased, and when using each boiler service efficiency it is more low.
