Abstract
The utility model discloses a special-purpose boiler for waste heat recovery and utilization of an all-around coke making enterprise. The upper part of a furnace body is a high-temperature flue gas heat exchange chamber, and the lower part is a combustion chamber. The high-temperature flue gas heat exchange chamber is provided with a heat exchange tube communicated with a steam pipeline. Two sides of the high-temperature flue gas heat exchange chamber are respectively provided with an air inlet pipeline and a smoke evacuation pipeline, and the air inlet pipeline is provided with a deduster. The smoke evacuation pipeline is provided with a filter, a coal economizer and an air pre-heater. The special-purpose boiler for waste heat recovery and utilization of an all-around coke making enterprise is advantageous in that high-temperature flue gas, fine ash and dust, coal tar auxiliary products, and coke oven gas, which are generated by coking process can be recovered and utilized; energy saving and emission reduction can be realized; energy consumption can be reduced, and energy waste can be prevented.
Description
Technical field
The utility model relates to industrial afterheat recovery and utilizes the field, relates in particular to the heat recovery of a kind of Almightiness type coal chemical enterprise boiler dedicated.
Background technology
Coking industry produces a large amount of waste heats in process of production, is generally to recycle by waste heat boiler.Simultaneously, in production technology, also can produce a large amount of flammable byproducts, discarded object etc., present waste heat boiler can't utilize above-mentioned resource, causes certain wasting of resources.In addition, because dust in the coking flue gas is more, pollute comparatively seriously, present waste heat boiler does not have facilitation to reducing smoke pollution.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of reasonable in design that the utility model provides, and the Almightiness type coal chemical enterprise heat recovery of the fume afterheat that produces in technique and flammable byproduct, waste ' s reclamation is boiler dedicated.
For realizing above-mentioned technical purpose, the utility model by the following technical solutions: the heat recovery of a kind of Almightiness type coal chemical enterprise is boiler dedicated, it is characterized in that: upper of furnace body is divided into the high-temperature flue gas Heat Room, and the bottom is divided into the combustion chamber; Be provided with the heat exchanger tube that is communicated with steam pipework in the high-temperature flue gas Heat Room, high-temperature flue gas Heat Room both sides are provided with admission line and smoke discharging pipe, and admission line is provided with deduster, and filter, economizer and air preheater are installed on smoke discharging pipe; Be provided with one-level fire grate and secondary fire grate in the combustion chamber, a side is provided with fuel port.
The utlity model has following beneficial effect: the high-temperature flue gas that coking process produces enters and carries out heat exchange in the high-temperature flue gas Heat Room, realize waste heat recovery, and the thin grey dust that produces in technique, coal tar byproduct, coke-stove gas enter the utilization of burning in the combustion chamber; The high-temperature steam pushing turbine that steam pipework produces rotates, and finally drives the generating set generating, realizes utilizing the purpose of coking fume afterheat, byproduct generating.
