The theoretical basis of this programme design is as follows: during can-type calcine furnace 1 produces ripe coke, the raw material of use are stone
Petroleum coke after changing industry oil refining, we are its green coke, we are its ripe burnt or calcined coke the coke after high-temperature calcination.It is
Heavy oil remaining solid product after 500-550 DEG C of heating of separating at high temperature goes out various oil products, volatile content is generally in 3%-
16%, aluminium generally uses 11% or so petroleum coke with raw material of wood-charcoal.The temperature of quirk is a 1100-1300 DEG C of left side in calcining furnace calcination process
The right side, the temperature in batch can at 1000 DEG C or so, at this temperature almost all of hydro carbons and other organic matters can all decompose or
Carbonization, the decomposition temperature of methane is 927 DEG C, so methane can also decompose at this temperature, their overwhelming majority all become
Carbon and hydrogen.Sulphur has also started a large amount of precipitations at this temperature.So fugitive constituent ingredient is relative to petroleum cracking and coking of coal
Gas is simply more, and main ingredient is hydrogen 80% or so and sulphur 10% or so, also containing a small amount of methane, carbon monoxide, two
Other substances such as carbonoxide, vapor, nitrogen, tar and carbon black, calcined ripe burnt fugitive constituent is less than 1%.
This programme uses extra fuel fugitive constituent extraction design scheme.The characteristics of this scheme, is: being worked as with external fuel
Calciner fuel carrys out heating and calcining furnace and replaces fugitive constituent, and fugitive constituent is extracted, this after desulfurization sulfur recovery and pretreatment
The content of treated fugitive constituent hydrogen can achieve 80%-90% or so, can burn up using it as fuel, can also regard thick hydrogen
Gas is sold, for example is sold to petroleum cracking industry, and better method is it further can be purified to 99% or more to become high-purity
Hydrogen can more promote value-added content of product and the performance of enterprises.Because being several times as much as Gas Prices by the price that ton calculates hydrogen.It does so
Have four big advantages: 1, petroleum green coke is in calcination process, and fugitive constituent is after sulfur recovery, hydrogen purification centrifugal station, high-purity
Hydrogen works as industrial chemicals to sell, remaining ingredient and natural gas are very close to as furnace body fuel, such economic benefit can mention significantly
High several times；2, increase desulfurizer, while producing sulphur, moreover it is possible to oven gas be allowed to reach environmental protection standard.Namely desulfurization is allowed to become
It must be easier, desulphurization plant is simple, and operation cost is low, and a large amount of sulfur products of abjection are also an economic well-being of workers and staff；3 is temperature automatically controlled
More easily, the method that multistage combustion can be used all controls fuel and combustion air, them is made to reach reasonable burning
Than.This is easily achieved control unattended and to each batch can fire path temperature of furnace body；4, vent gas treatment is used and is opened one's minds,
Since fuel uses natural gas for raw material, sulfur content is extremely low, meets National Fuel Gas standard, too small, the tail gas meeting of air-fuel ratio control
Containing a small amount of methane, carbon monoxide, these substances are handled by select existing tail gas chemical catalysis reduction apparatus, it is such
Device does not have to personal management, and operation cost substantially reduces.5, waste heat can recycle, and save more fuel.
In order to reach better combustion efficiency, automatic temperature controlling combustion system in this programme contains the flue gas oxygen of system
Amount meets National Fuel Gas boiler standard, oxygen content of smoke gas < 3%.In order to reach this target, it is necessary to gaseous fuel and combustion-supporting sky
The ratio of combustion strict control of gas.By the automated system in this programme, temperature is controlled with temperature sensor, is sensed with oxygen content
Device controls ratio of combustion.The amount for increasing combustion gas when temperature is inadequate, increases preheated air amount when oxygen content is inadequate.Conversely, then subtracting
It is few.
Energy-saving efficiency is theoretically up to 75% in this programme, and the energy conversion of saving at the production with economic value
Product: hydrogen.Hydrogen is the industrial chemicals being widely used, and is worth very high.Its economic benefit value is far superior to cogeneration.
Input cost is also far smaller than cogeneration.In addition, environmental issue is solved, the exhaust gas volumn of processing is greatly reduced, base
Originally it can accomplish three-waste free discharge, the investment of environmental protection equipment also greatly reduces.
Using the production system of this programme, available three kinds of products: calcined coke, the hydrogen of 99% purity, 99% purity
Sulphur is greatly improved economic benefit；It is precisely temperature automatically controlled to greatly facilitate realization, temperature can be precisely controlled most is having
