Description

Hot-blast stove fume comprehensive utilization device in a kind of aluminium polychloride production
Technical field
The utility model belongs to tail gas disposal technique field, and in particular to hot-blast stove fume in a kind of aluminium polychloride production Comprehensive utilization device.
Background technology
In aluminium polychloride production, hot-blast stove is often needed to be provided for drying plant for drying aluminium polychloride product Hot-air.Hot-blast stove includes coal burning machine, coal is delivered in coal burning machine by coaling machine in actual applications, and pass through air blower Combustion air is provided for coal burning machine;In the prior art typically using the air around coal burning machine as combustion air, but in the winter Energy dissipation can be caused as combustion air using the cold air in surrounding environment during season, while dew can be produced inside coal burning machine Water, equipment corrosion is easily caused, shorten service life of equipment.Therefore in view of the above-mentioned problems, being necessary that it is fire coal to establish a set of The smoke comprehensive that machine provides combustion air utilizes device.
Utility model content
Technical problem to be solved in the utility model is:Hot-blast stove fume in a kind of aluminium polychloride production is provided to integrate Using device, to solve energy dissipation, and dew etching apparatus, shorten the technical problem of service life of equipment.
In order to solve the above technical problems, the technical solution of the utility model is:
Hot-blast stove fume comprehensive utilization device in a kind of aluminium polychloride production, including hot-blast stove, the hot-blast stove include Coal burning machine and combustion fan, the coal burning machine are provided with exhanst gas outlet and combustion air inlet, and the exhanst gas outlet connects heat exchanger, The thermal source outlet of the heat exchanger is connected by combustion fan described in off-gas recovery pipeline communication, the air outlet of the combustion fan The combustion air inlet of the coal burning machine.
As an improvement technical scheme, the off-gas recovery pipeline also connects exhaust duct, and the exhaust duct connects Logical smoke eliminator, the exhanst gas outlet connection aluminium polychloride drying tower of the smoke eliminator.
As an improvement technical scheme, the off-gas recovery pipeline is provided with air-introduced machine.
As an improvement technical scheme, be respectively equipped with control valve on the off-gas recovery pipeline and exhaust duct.
After employing above-mentioned technical proposal, the beneficial effects of the utility model are:
Because including hot-blast stove, hot-blast stove includes coal burning machine and combustion fan, coal burning machine is provided with exhanst gas outlet and combustion-supporting sky Gas import, exhanst gas outlet connection heat exchanger, the thermal source outlet of heat exchanger pass through off-gas recovery pipeline communication combustion fan, combustion air The combustion air inlet of the air outlet connection coal burning machine of machine.In actual applications, entered by high-temperature flue gas caused by hot-blast stove In heat exchanger, heat caused by high-temperature flue gas is to realize the heating to reaction mass, while will by off-gas recovery pipeline Combustion air of the high-temperature flue gas of recovery as coal burning machine, both reduces energy loss, promotes coal combustion, improves the combustion of coal Burning rate, while corrosion of the dew to equipment can be also prevented, extend the service life of equipment.
Because off-gas recovery pipeline also connects exhaust duct, exhaust duct connection smoke eliminator, smoke eliminator Exhanst gas outlet connection aluminium polychloride drying tower.In actual applications, the flue gas of hot-blast stove discharge passes through smoke eliminator After processing, it may also be used for dry aluminium polychloride product.
Because off-gas recovery pipeline is provided with air-introduced machine.By this design, it is easy to flue gas to enter in coal burning machine.
Brief description of the drawings
Fig. 1 is hot-blast stove fume comprehensive utilization device structural representation in a kind of aluminium polychloride production of the utility model;
Wherein, 1- coal burning machines, 2- combustion fans, 3- heat exchangers, 4- off-gas recovery pipelines, 5- exhaust ducts, 6- flue gases are net Makeup is put, 7- aluminium polychloride drying towers, 8- air-introduced machines.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.
As shown in figure 1, hot-blast stove fume comprehensive utilization device in a kind of aluminium polychloride production, including hot-blast stove, hot blast Stove includes coal burning machine 1 and combustion fan 2, and coal burning machine 1 is provided with exhanst gas outlet and combustion air inlet, exhanst gas outlet connection heat exchanger 3, the thermal source outlet of heat exchanger 3 connects combustion fan 2, the air outlet connection coal burning machine of combustion fan 2 by off-gas recovery pipeline 4 1 combustion air inlet, air-introduced machine 8 is wherein additionally provided with off-gas recovery pipeline 4.
In actual applications, flue gas caused by hot-blast stove is after heat exchanger, and by air-introduced machine, part of smoke is along cigarette Gas recovery channel enters inside coal burning machine, the combustion air as coal burning machine;Another part flue gas enters cigarette along exhaust duct Air purifying apparatus, after smoke eliminator is handled, clean flue gas is used to dry aluminium polychloride product;In addition high temperature cigarette When gas passes through heat exchanger, heat caused by high-temperature flue gas can be additionally used in heated material.
As an improvement off-gas recovery pipeline 4 also connects exhaust duct 5, exhaust duct 5 connects smoke eliminator 6, The exhanst gas outlet connection aluminium polychloride drying tower 7 of smoke eliminator 6.In actual applications, flue gas is beaten after heat exchanger The control valve to begin to rehearse on wind pipeline, part of smoke enter smoke eliminator along exhaust duct, after treatment, entered back into Aluminium polychloride drying tower is used to dry aluminium polychloride.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
