Abstract
The utility model discloses a waste water evaporation plant in coal fired boiler stove, including coal fired boiler who is arranged in the coal burning and the dust remover that is used for getting rid of flue gas dust granule, be equipped with the follow -up flue that is used for discharging the ash pipeline way of dust granule and is used for transport filtration back flue gas on the dust remover, coal fired boiler and dust remover pass through dedusting flue and feed through, be equipped with atomizing nozzle in the coal fired boiler, the coal fired boiler peripheral hardware has the water pump that is used for extracting waste water, and atomizing nozzle and water pump pass through the pipeline intercommunication. The device make full use of existing equipment and flue gas heat, it becomes vapor to have distributed the pervaporation with the waste water normal water, and the pollutant in the waste water evaporates the post crystallization for solid -state at moisture completely to make moisture and pollutant clean separation in the waste water be convenient for deal with differently, with the thorough innocent treatment who realizes boiler waste water.
Description
Technical field
This utility model is specifically related to waste evaporator plant in a kind of coal boiler.
Background technology
The energy characteristics of China is gas oil-poor, few, rich coal, and coal occupies the energy output of country more than 70% always.Coal-burning boiler is exactly fuel is coal-fired boiler, refer to through fire coal combustion heat release amount in burner hearth, heat medium water or other organic heat carrier (such as heat conduction wet goods) being heated to the thermal powerplant of uniform temperature (or pressure), coal-burning boiler is the most extensive approach of coal utilization.Along with the continuous reinforcement of Environmental protection, produced by coal-burning boiler, all kinds of waste water need progressively to realize zero-emission, and the sustainable development of coal-burning boiler field is proposed severe challenge by this.
Traditional coal-burning boiler waste water treatment process, all adopt chemistry dosing and the method for physics sedimentation, the method flow process is complicated, operation expense is high, and it is only capable of the partial contamination thing composition in waste water, waste water after handled still can not be secondary use, therefore a large amount of waste water will appear from nowhere can with the situation that can arrange.
Utility model content
The purpose of this utility model is in that to overcome the shortcoming of prior art, it is provided that waste evaporator plant in a kind of coal boiler, to solve the partial contamination thing composition that existing coal-burning boiler is only capable of in waste water, the problem that remaining waste water cannot process.
For achieving the above object, technical solution adopted in the utility model is: provide waste evaporator plant in a kind of coal boiler, including the coal-burning boiler for coal combustion with for removing the cleaner unit of dust granule in flue gas, cleaner unit is provided with the ash handing pipeline for discharging dust granule and for the follow-up flue of flue gas after delivery of filtered, and coal-burning boiler is connected by dust-removing flue with cleaner unit；Being provided with atomizer in coal-burning boiler, coal-burning boiler is externally provided with the water pump for extracting waste water, and atomizer and water pump pass through pipeline connection.
The beneficial effects of the utility model are:
1, this utility model makes full use of existing equipment and flue gas heat, moisture in waste water is evaporated completely and becomes steam, the crystallization after moisture evaporates completely of pollutant in waste water is solid-state, so that moisture and pollutant in waste water are kept completely separate and are easy to process respectively, to realize the thorough harmless treatment of boiler wastewater.
Accompanying drawing explanation
Fig. 1 is the structural representation of waste evaporator plant in coal boiler.
Wherein: 1, coal-burning boiler；2, water pump；3, atomizer；4, dust-removing flue；5, cleaner unit；6, ash handing pipeline；7, follow-up flue.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with this utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to Fig. 1, the present embodiment provides waste evaporator plant in a kind of coal boiler, including the coal-burning boiler 1 for coal combustion with for removing the cleaner unit 5 of dust granule in flue gas, cleaner unit 5 is provided with the ash handing pipeline 6 for discharging dust granule and for the follow-up flue 7 of flue gas after delivery of filtered, and coal-burning boiler 1 is connected by dust-removing flue 4 with cleaner unit 5；Being provided with atomizer 3 in coal-burning boiler 1, coal-burning boiler 1 is externally provided with the water pump 2 for extracting waste water, and atomizer 3 and water pump 2 pass through pipeline connection.
Waste water evaporation technology in a kind of coal boiler, comprises the following steps:
Water pump 2 extract waste water through pressurization after flow to atomizer 3, atomizer 3 by waste water atomized spray inside coal-burning boiler 1.
Moisture in atomization waste water evaporates completely in coal-burning boiler 1 becomes steam, and the crystallization after moisture evaporates of the pollutant in atomization waste water is solid-state.
Steam and solid contaminant enter cleaner unit 5 by dust-removing flue 4, and solid contaminant enters ash handing pipeline 6 after being caught by cleaner unit 5, and steam enters follow-up flue by cleaner unit 5.
This device makes full use of existing equipment and flue gas heat, moisture in waste water is evaporated completely and becomes steam, the crystallization after moisture evaporates completely of pollutant in waste water is solid-state, so that moisture and pollutant in waste water are kept completely separate and are easy to process respectively, to realize the thorough harmless treatment of boiler wastewater.This device technique clear process, the device of increase is few convenient to carry out and with low cost, and is capable of the zero-emission of boiler wastewater.
Above-mentioned embodiment is used for illustrating this utility model; rather than this utility model is limited; in spirit of the present utility model and scope of the claims, any amendment that this utility model is made and change, both fall within protection domain of the present utility model.
