Description
Technical field
The utility model belongs to hydrogen manufacturing conversion furnace technical field, specifically, is related to a kind of top based on double tube reactor
Burning formula hydrogen manufacturing conversion furnace.
Technical background
Hydrogen manufacturing conversion furnace is the core of device for producing hydrogen, interior to include hydrogen production conversion reactor, and the reactor is a kind of external-heat
Shell-and-tube reactor, due to conversion reaction highly endothermic and high temperature the features such as, this reactor is designed to the form of heating furnace, urges
Agent directly heats, reaction medium is entered by the beds in boiler tube in reformer tube one by one in burner hearth
Row reaction.
Hydrogen production conversion double tube reactor can realize 600 DEG C -850 DEG C in high-temperature product gas of high-temperature position heat by
Central tube self-loopa is set up in reaction tube and is used for heating response gas, one-way heating is two-way confession in pipe outer tube on the outside of change reaction tube
Heat, so as to reduce fuel consumption and energy consumption, turn into a direction of hydrogen manufacturing conversion furnace reactor research.But due to hydrogen manufacturing conversion furnace
Heating-up temperature is high, and response intensity is big, and simple sleeve structure can not adapt to the stress variation under high temperature, is easy to cracking etc. and asks
Topic.
Device for producing hydrogen reburner is classified by radiation chamber heat-supplying mode, can be divided into following four mode：Tipburn stove, side are burnt
Stove, halfpace stove, bottom fired heater.
The burner of tipburn stove is arranged at the top of radiation chamber, and flame burns from top to bottom, in flow of flue gas direction and conversion tube
Media flow direction is identical, and heat transfer type conducts heat for cocurrent.Sidefired furnace burner is arranged on radiation chamber side wall, the combustion of flame attached wall
Burn, conversion tube is conducted heat by radiant wall, flow of flue gas direction and media flow in pipe are in opposite direction, and heat transfer type cross-flow passes
Heat.The burner row of halfpace stove is fewer than sidefired furnace, is a kind of improved cross-flow heat transfer.Bottom fired heater is countercurrent heat-transfer.
Due to different heat transfer types, so the different type of furnaces have different calorific intensitys and tube wall temperature distribution.Tipburn stove
Flame concentrates on roof of the furnace, and it is top burning type reburner that highest tube wall temperature and calorific intensity peak value occur at the top of conversion tube simultaneously
The characteristics of.For side burning and halfpace reburner, because burner is evenly distributed on the different level along pipe range direction, radiant heat transfer
Than more uniform, it is allowed to higher conversion gas outlet temperature, improve the yield of hydrogen.Bottom fired heater has furnace roof heat on heat transfer property
Low intensity, the high characteristic of heat intensity of hearth, thus furnace wall temperature change is maximum, furnace wall temperature is all type of furnaces particularly at furnace bottom
Middle highest, it is very unfavorable to the boiler tube life-span, in order to control highest tube wall calorific intensity not exceeded, very low evenly heat can only be selected strong
Degree, the huge waste of tubing is caused, so large-scale plant does not use bottom fired heater.
All conversion tubes of tipburn stove and bottom fired heater are arranged in same burner hearth, and arrangement is compact, save floor space,
Suitable for maximization.Sidefired furnace and the maximization of halfpace stove have certain difficulty.The burner dense arrangement of tipburn stove is in furnace roof, fuel
Pipe arrangement and air line accordingly simplify, but top construction is more complicated.
Over nearly 15 years, the Chinese patent on hydrogen manufacturing conversion furnace shares more than 100, wherein 2/3 is patent of invention.These are special
It is anti-that profit according to key structural feature can be divided into traditional burner improvement, heat-exchanged reformer, fluidized-bed reactor, fixed catalyst bed
Answer device, using the class of the reactor of catalyst layer and other patents related to hydrogen manufacturing conversion furnace etc. six.Hydrogen manufacturing conversion furnace it is special

Reburner accounts for the 28% of patent sum, and the patent of fluidized-bed reactor accounts for always 11%, and traditional burner is improved patent and is concentrated mainly on
The several respects such as furnace tube structure and connection, burner and reburner material.
At this stage there is the problem of energy consumption is big in hydrogen manufacturing conversion furnace, and transform portion is the main energy consumption element of device, existing rank
Section device for producing hydrogen comprehensive energy consumption more than 1000 kilograms mark oil/tons, typically constitute from modern refinery's total energy consumption 3% and more than.Main cause
For in existing steam reformation hydrogen production technique, steam and about 500 DEG C of entrance of hydrogen feedstock mixture by pretreatment are reforming
Stove is filled with the reaction tube of catalyst, is reacted through combustion heating, and a maximum of about of 850 DEG C of product gas goes out reburner and enters waste heat
Boiler produces high steam.This flow radiant section thermic load only accounts for more than 50%, and remaining is reclaimed by flue gas energy recovery section, about
10% energy for accounting for gross heat of combustion is converted into outer defeated steam, so reforming high energy consumption, hydrogen manufacturing cost remains high, conversion
Furnace volume is huge.Due to the maximization of device, the thermal expansion problem of hydrogen manufacturing conversion furnace pipeline system is more and more prominent.Substantial amounts of heat
Expansion issues will be by the thermal expansion such as tail pipe and spring support hanging frame absorber element and being reserved with enough expansion rooms to solve.
