Abstract
The utility model discloses calcium plaster processing unit in a kind of heat-engine plant wet desulphurization system, including gypsum cyclone, dewaterer, filtrate water box and gypsum overflow baffle-box, it is connected on the overflow pipe of the gypsum overflow baffle-box above pipeline to the filter cloth of dewaterer；Filtrate branches on the filter cake of dewaterer and makes chlorion, heavy metal be attached on filter cake to take desulphurization system out of in gypsum overflow baffle-box when dewaterer is run.Substantial amounts of chlorion, heavy metal are avoided with the operation for corroding influence equipment after desulphurization plant or precipitation fouling in filtrate together blowback desulphurization system.
Description
Technical field
The utility model is related to a kind of thermal power plant's wet desulfurization system, more particularly to a kind of heat-engine plant wet desulphurization system
Middle calcium plaster processing unit.
Background technology
Electric power is the important energy source of the national economic development, and thermal power generation is China and many countries produce electric energy in the world
Main method.Coal burns liberated heat in boiler, water is heated into the steam with certain pressure and temperature, then
Steam does work along pipeline into turbine expansion, drives the rotation of the superhigh speed of generator one, comes so as to send electricity.Done in steam turbine
The steam of complete work(is discharged into cold vapour device and condenses into water, is then condensed water pump feeding oxygen-eliminating device.Water in oxygen-eliminating device by from
The extracted steam from turbine of exhaust tube heats and removes contained gas, last to be repeated to participate in above-mentioned circulation in feedwater pumped back boiler again
Process.Inevitable thermal power generation can produce the substantial amounts of tail gas and waste gas for damaging environment, and sulfur dioxide is mainly harmful gas
One of body, the desulfurization means that the gypsum desulfurization in wet desulphurization is commonly used for thermal power plant, but exist in this desulphurization system useless
The process problem of water.From the point of view of current use situation, although thermal power plant has put into the processing that substantial amounts of energy carries out waste water, but
It is that existing waste water system equipment still has many defects, reliability is not high, it is often necessary to prolonged maintenance.Overhauling
Waste water system can not put into operation in journey, and chlorion, content of beary metal are too high during this period, easily cause desulphurization plant corrosion and scaling
Seriously, the normal operation of desulphurization plant is influenceed.
Utility model content
The purpose of this utility model is that providing one kind can effectively reduce when desulphurization system wastewater treatment equipment is overhauled
Calcium plaster processing unit in chlorion, the heat-engine plant wet desulphurization system of content of beary metal.
Calcium plaster processing unit in this heat-engine plant wet desulphurization system that the utility model is provided, including gypsum eddy flow
Pipeline is connected on device, dewaterer, filtrate water box and gypsum overflow baffle-box, the overflow pipe of the gypsum overflow baffle-box to de-
Above the filter cloth of water dispenser；Dewaterer run when gypsum overflow baffle-box in filtrate branch on the filter cake of dewaterer make chlorion,
Heavy metal, which is attached on filter cake, takes desulphurization system out of.
The pipeline is provided with switch valve.
The top of the gypsum overflow baffle-box is provided with agitator.
The utility model is after coming into operation, when waste water system is normally run, and the switch valve in control pipeline, which is in, to close
Closed state, gypsum acts on forming byproduct by dewaterer after calcium plaster is acted on through gypsum cyclone, and filtrate enters gypsum overflow
Baffle-box, is partly into a filtrate water box part and is pumped out by waste water system；When waste water system is in inspecting state, control
Switch valve on pipeline is in open mode, and gypsum acts on forming by-product by dewaterer after calcium plaster is acted on through gypsum cyclone
Product, filtrate is flow on the filter cake of dewaterer into a gypsum overflow baffle-box part, chlorion, heavy metal is attached to gypsum filter cake
On take desulphurization system out of.Substantial amounts of chlorion, heavy metal are avoided with corroding desulphurization plant in filtrate together blowback desulphurization system
Or influence the operation of equipment after precipitation fouling.
Brief description of the drawings
Fig. 1 is the arrangement schematic diagram of one preferred embodiment of the utility model.
Illustrate sequence number：
1-gypsum cyclone, 2-dewaterer, 3-filtrate water box, 4-gypsum overflow baffle-box, 5-agitator, 6-open
Close valve.
Embodiment
As shown in figure 1, calcium plaster processing unit in this heat-engine plant wet desulphurization system that the present embodiment is provided, including stone
Agitator 5 is provided with cream cyclone 1, dewaterer 2, filtrate water box 3 and gypsum overflow baffle-box 4, gypsum overflow baffle-box 4.
When desulphurization system works, the calcium plaster flowed out from absorption tower is separated into the gypsum slurries of concentration by gypsum cyclone
And filtrate, formation by-produced gypsum is exported after the gypsum slurries of concentration are acted on through dewaterer, and filtrate enters gypsum overflow baffle-box
It is interior, and be stirred by agitator 5.Gypsum overflow baffle-box is provided with overflow pipe, and overflow pipe has two delivery outlets, one
Delivery outlet is connected with filtrate water box, and the overflow pipe that another delivery outlet is delivered to filtrate at the top of dewaterer, dewaterer is provided with
Switch valve 6.
When waste water system can normally be run, the switch valve on control overflow pipe is closed, and calcium plaster is through stone
Cream cyclone is acted on and separation of solid and liquid, and the gypsum slurries of concentration are transported at dewaterer, act on forming gypsum by dewaterer,
Exported as the byproduct of desulphurization system；And filtrate then enters in gypsum overflow baffle-box, and stirred by mixer, it is to avoid defeated
Go out the phenomenon of substantial amounts of deposition, the filtrate after stirring is partly into blowback after filtrate water box and recycled into desulphurization system,
Another part is pumped out by waste water system.When waste water system is in inspecting state, the switch valve in control pipeline, which is in, to be opened
State, separation of solid and liquid after calcium plaster is acted on through gypsum cyclone, the gypsum slurries of concentration are after dewaterer is acted on as desulfurization
The byproduct of system is exported so that it is used；And filtrate then enter gypsum overflow baffle-box in, agitated device stir after filter
A liquid part is flow on the filter cake of dewaterer, chlorion, heavy metal is attached on gypsum filter cake and is taken desulphurization system out of, it is to avoid a large amount of
Chlorion, heavy metal corrode desulphurization plant or precipitation fouling into desulphurization system with the common blowback of filtrate, improve desulfurization system
The operation stability of system.
