The separator is disposed with a main air introducing machine and a sub air introducing machine, the smoke separated by the sub air introducing machine will recirculated in the furnace and will be burnt, the tower cover of the cracking tower is opened with a waste gas inlet through which the all industrial waste gas of the waste gas generating devices in the load system of the heat conducting oil furnace is fed into the cracking tower by an industrial waste gas air introducing machine through a gas searching pipe and a gas feeding pipe in order to be gasified and burnt. The device also has unite integrative energy saving and environmental protection mechanism.

Description

The outer circulation coal smoke-eliminating heat-conductive oil oven that a kind of and poisonous industrial waste gas connection is searched and burnt

The present invention relates to the outer circulation coal smoke-eliminating heat-conductive oil oven technology that a kind of and poisonous industrial waste gas connection is searched and burnt, when especially being provided with not only having concurrently of cleavage column that the refractory brick of capping suitable for reading builds by laying bricks or stones in the coil pipe inner chamber thorax of the conduction oil loop body that makes progress in the coal-fired furnace cavity exit existing indusrial toxic exhaust emission effectively purified but also coal-fired cleaningization and return the heat-conducting oil furnace of cigarette after-flame smoke elimination by the outer circulation smoke separator.

At present, known heat-conducting oil furnace, all fire coals must be given birth to cigarette.Both made is that the COAL-WATER SLURRY TECHNOLOGY application also can't use the bag-type dusting flue dust to exceed standard because of exhaust gas temperature is higher; The industrial circle of especially present all application heat-conducting oil furnaces, often be accompanied by the polymerization in the heat conduction work, distillation, concentrate, fusion, grease decomposes, deodorization, heat is walked type, oven dry, pad-dry-cure dyeing, stoving of the paint, dry, hot setting and pitch dissolving, the coating heating, the ornament materials heating, waterproof material, malthoid is produced, hot-forming, production process such as plastics and rubber industry accompany a large amount of poisonous fumes pollute all can't comprehensive purifying or pollution treatment with high costs, the most long-standing abuses of industrial waste gas pollution problem that make China various places are difficult environmental protection problem and can't plan as a whole for a long time to solve.

The objective of the invention is: at first the smoke abatement and dust control that flue gas is collected recirculation after separation under the burning device configuration of cigarette smoke separator is returned in the technical realization outer circulation of the coal combustion equipment of conduction oil is relatively thoroughly changed, install xeothermic cleavage column additional and introduce indusrial toxic waste gas and realize hydrocarbon reorganization oxidizing fire then under the thermal cracking condition at Oil Guide stove furnace outlet again, with this realize in all production processes that adopt heat-conducting oil furnaces organic toxic waste gas in the lump in purified treatment and the coal-fired process relative smoke abatement and dust control completely need not obviously increase cost and combine in heat-conducting oil furnace, for the energy-conserving and environment-protective cause of China is made bigger contribution.

The object of the present invention is achieved like this: open on the chain fire-gate burner hearth Hou Qiang of routine top and return cigarette and go into fire door (the oblique cigarette that returns of upper furnace one wing furnace wall of fixed grate is gone into fire door); And establish the refractory irregular block cleavage column bucket just that circle prolongs port tube upper cover on (side) post at the furnace outlet place, bucket end opening and furnace outlet dock entirely only on the bucket interface side to around open some mistake burners and the tower caping is opened the exhaust gas entrance that joins with the industrial waste gas air duct, the logical waste gas of mouth is collected Blower for sucking or supplying, power traction is searched feed channel, the road connects each generation equipment of industrial waste gas, the smoke neck feeds smoke separator, and (smoke separator is very effective through practical validation, it revolves chimney by bilayer and forms, the inner core group establishes smoke-dividing hole, the outer negative pressure of mouth is drawn cigarette, cigarette is crossed auxiliary induced draft fan and is returned in the stove), the flue gas that device draws purification by main induced draft fan is sent to chimney and goes, and device is entered the black smoke separated and powder ash fine coal outer circulation in the lump by auxiliary induced draft fan and returns cigarette and go into fire door.Like this, upward normally coal-fired as fire grate row, then the nature of the raging fire in the burner hearth burns the cleavage column tube aglow, makes the interior temperature maintenance of its tower in the 1300 ℃ left and right sides levels approaching with fire box temperature.The cigarette of being given birth to, drawn the smoke neck by crossing burner by negative pressure again prior to the tower inside vortex, then enter in the outer smoke separator of stove (because the double-deck cigarette speed of revolving of revolving in the chimney is quite high, all flue dust are all given to paste along seizing the opportunity on the inner tube wall at the centrifugal force of at a high speed rotation and are introduced by outer negative pressure and separate with purifying gas flow) crossed by auxiliary induced draft fan and return the smoke pipe road and send into and return cigarette and go into fire door, institute's smoke discharging (certainly, have an amount of dispensing two, tertiary air) enter burner hearth and fire again (so, all cigarettes and moving in circles are up to after-flame); Meanwhile, each industrial waste gas generation poisonous fume that equipment produces is crossed by air-introduced machine and is searched feed channel and push the waste gas air duct exhaust gas entrance that stimulates the menstrual flow and enter within the Pintsch process Tata thorax, interior continuous high temperature has been kept the thermal cracking condition of poisonous fume molecule and has been made it hydrocarbon reorganization and oxidation after-flame under suitable oxygenating condition, so, poisonous industrial waste gas has become utilizable second energy of cleanization and has stopped environmental pollution.

Owing to adopted such scheme, the heat-conducting oil furnace that the present invention has not only given the high temperature smoke evacuation recycles after-flame formula smoke elimination performance and effectively captures ultrafine dust through the outer circulation separated smoke at coal-fired process, but also can be being thermally cracked to elementary gas and burning without exception by the poisonous fume of collecting of having ready conditions such as being produced in production such as pitch dissolving, printing and dyeing, thermal finalization because of thermal procession volatilization in the industrial equipment of this heat-conducting oil furnace institute load, the surplus row's of institute burnt gas or carry out the replacement technology of devulcanizer processing formation heat-conducting oil furnace of new generation at afterbody again.
