Abstract
The invention discloses an in-furnace wastewater evaporation device and process for a coal-fired boiler. The device comprises a coal-fired boiler and a dust remover, wherein an ash conveying pipeline and an subsequent flue are arranged on the dust remover, and the coal-fired boiler and a dust remover are communicated with each other through a dust removal flue; and an atomizing nozzle is arranged in the coal-fired boiler, a water pump is arranged outside the coal-fired boiler, and the atomizing nozzle and the water pump are communicated through a pipeline. The process comprises the following steps: wastewater is pumped by virtue of the water pump, is pressurized, is introduced to the atomizing nozzle and is sprayed into the coal-fired boiler by virtue of the atomizing nozzle; pollutants in the atomized wastewater are crystallized into solids after moisture is evaporated; and the solid pollutants are captured by the dust remover and are discharged into the ash conveying pipeline, and water vapor is discharged into the subsequent flue by virtue of the dust remover. According to the device and the process, the moisture in the wastewater is completely evaporated into water vapor by virtue of existing equipment and the heat of flue gas, and the pollutants in the wastewater are crystallized into solids after the moisture is evaporated, so that the moisture and the pollutants in the wastewater are completely separated so as to be respectively processed, and the thorough innocent treatment of the wastewater of the boiler is realized.
Description
Technical field
Present invention relates particularly to waste evaporator plant and technique 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 of country more than 70% always
Output.Coal-burning boiler be exactly fuel be coal-fired boiler, refer to through fire coal combustion heat release amount in burner hearth,
Heat energy heat medium water or other organic heat carrier (such as conduction oil etc.) being heated to uniform temperature (or pressure) moves
Power equipment, coal-burning boiler is the most extensive approach of coal utilization.Continuous along with Environmental protection
Strengthening, all kinds of waste water produced by coal-burning boiler need zero-emission is done step-by-step, and this can to coal-burning boiler field
Sustainable development proposes severe challenge.
Traditional coal-burning boiler waste water treatment process, all uses chemistry dosing and the method for physics sedimentation, the party
Method flow process is complicated, operation expense is high, and is only capable of the partial contamination thing composition in waste water, handled
After waste water still can not be secondary use, therefore a large amount of waste water will appear from nowhere can with the situation that can arrange.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that waste water evaporation in a kind of coal boiler
Device and technique, to solve the partial contamination thing composition that existing coal-burning boiler is only capable of in abjection waste water, remaining
The problem that waste water cannot process.
For achieving the above object, the technical solution used in the present invention is:
Waste evaporator plant in a kind of coal boiler is provided, including for coal combustion coal-burning boiler and for
Remove the cleaner unit of dust granule in flue gas, cleaner unit be provided with the ash handing pipeline for discharging dust granule and
The follow-up flue of flue gas after delivery of filtered, coal-burning boiler is connected by dust-removing flue with cleaner unit；Coal-fired
Being provided with atomizer in boiler, coal-burning boiler is externally provided with the water pump for extracting waste water, atomizer and water pump
Pass through pipeline connection.
Waste water evaporation technology in a kind of coal boiler, comprises the following steps:
Water pump extraction waste water flows to atomizer after pressurization, and waste water atomized spray is being fired by atomizer
Inside coal burning boiler；
The evaporation completely in coal-burning boiler of moisture in atomization waste water becomes steam, the pollution in atomization waste water
Thing crystallization after moisture evaporates is solid-state；
Steam and solid contaminant enter cleaner unit by dust-removing flue, and solid contaminant is caught by cleaner unit
After enter ash handing pipeline, steam enters follow-up flue by cleaner unit.
The invention have the benefit that
1, the present invention makes full use of existing equipment and flue gas heat, is evaporated completely by moisture in waste water and becomes water steaming
Gas, it is solid-state that the pollutant in waste water crystallize after moisture evaporates completely, so that the moisture in waste water and dirt
Dye thing is kept completely separate to be 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.
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 object, technical solutions and advantages of the present invention clearer, specifically real below in conjunction with the present invention
Execute example and technical solution of the present invention is clearly and completely described by corresponding accompanying drawing.
With reference to Fig. 1, the present embodiment provides waste evaporator plant in a kind of coal boiler, including for coal combustion
Coal-burning boiler 1 and for removing the cleaner unit 5 of dust granule in flue gas, cleaner unit 5 is provided with for discharging
The ash handing pipeline 6 of dust granule and the follow-up flue 7 of flue gas, coal-burning boiler 1 and dedusting after delivery of filtered
Device 5 is connected by dust-removing flue 4；Being provided with atomizer 3 in coal-burning boiler 1, coal-burning boiler 1 is externally provided with use
In the water pump 2 of extraction waste water, 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 extracts waste water and flows to atomizer 3 after pressurization, and atomizer 3 is by waste water atomized spray
Inside coal-burning boiler 1.
The evaporation completely in coal-burning boiler 1 of moisture in atomization waste water becomes steam, the dirt in atomization waste water
The crystallization after moisture evaporates of dye thing is solid-state.
Steam and solid contaminant enter cleaner unit 5 by dust-removing flue 4, and solid contaminant is by cleaner unit 5
Entering ash handing pipeline 6 after seizure, steam enters follow-up flue by cleaner unit 5.
This device makes full use of existing equipment and flue gas heat, and being evaporated completely by moisture in waste water becomes steam,
It is solid-state that pollutant in waste water crystallize after moisture evaporates completely, so that the moisture in waste water and pollutant
