Moisture content in desulfurizing tower exiting flue gas is up to 10%~15%, and usual flue-gas temperature is about 50 DEG C.Since desulfurizing tower can not
It is fully effective to remove environmentally harmful fine particle, condensable particulate matter, environmental effects can be contained with flue gas emission
There is the flue gas of vapor to mix after chimney discharge with cold air, causes the vapor in flue gas to condense suddenly and form white cigarette, make
At visual pollution.
Utility model content
The purpose of the utility model is to provide a kind of devices for eliminating condensable particulate matter, can effectively remove desulfurization
Entrained condensable particulate matter in tower exiting flue gas, and the visual pollution of chimney white cigarette can be eliminated to a certain extent.
In order to solve the above technical problems, the utility model adopts the following technical solutions: a kind of elimination condensable particulate matter
Device, including module frame, flue gas condensing heat exchanger, cold water sprays device and flue demister, the module frame setting
In flue section after desulfurizing tower and before chimney, it is horizontally disposed with or is vertically arranged, the cold water sprays along flue gas direction
Device is electrically connected with the controller, and the flue gas condensing heat exchanger, cold water sprays device, flue demister are all set in module frame
Interior, cold water sprays device is arranged between flue gas condensing heat exchanger and flue demister.
In a kind of device for eliminating condensable particulate matter above-mentioned, the cold water sprays device includes spray gun, the spray
Mist rifle is connect by rotating device with jet pipe.Spray gun realizes that 360 degree of angle rotates by rotating device, by adjusting spraying
The spray angle of rifle can make it as the flusher for rinsing flue demister, realize the multifunctionality of equipment, improve self-cleaning
Ability.
In a kind of device for eliminating condensable particulate matter above-mentioned, gas-liquid two-phase flow nozzle is provided on the spray gun.
The advantage of gas-liquid two-phase flow nozzle is used to be that the partial size of the sprayed atomized drop of this kind of nozzle can reach 40 μm~80 with very little
μm.The atomized drop for ejecting this minimum partial size can greatly increase contact area with flue gas, can make flue gas when extremely short
Interior completion heat transfer process achievees the purpose that reducing temperature twice amplitude up to 1~3 DEG C.
In a kind of device for eliminating condensable particulate matter above-mentioned, the material of the module frame is stainless steel material.It adopts
It is corrosion-resistant, service life is high with the module frame of stainless steel material.
In a kind of device for eliminating condensable particulate matter above-mentioned, the flue demister is baffle plate type flue demisting
Device.
Since the process of reducing temperature twice needs to spray into atomized drop, the flue gas condensing in a temperature-fall period is precipitated in addition
Droplet has part and carries with flue gas, in order to avoid this two parts drop enters chimney with flue gas, causes Wet chimney phenomenon.Cause
This, is arranged baffle plate flue demister, captures to these drops, avoided Wet chimney phenomenon.
In a kind of device for eliminating condensable particulate matter above-mentioned, flue gas condensing heat exchange lower section is provided with catch basin.
Catch basin is for collecting the droplet being precipitated after vapor is condensed.
Compared with prior art, the utility model makes the vapor contained in flue gas be condensed precipitation by cooling for the first time,
The water capacity of flue gas is reduced, thus since the white cigarette that vapor condenses suddenly and generates is existing after the discharge that removes smoke to a certain extent
As, while removing part particulate matter influential on environment；Droplet is further precipitated by reducing temperature twice, utilizes further analysis
The characterization of adsorption of droplet and particulate matter out increases particulate matter volume and quality, then substantially by the capture of flue demister
Long-pending particulate matter improves efficiency of dust collection so as to effectively remove the particulate matter carried in desulfurizing tower exiting flue gas；First cooling
The droplet that condensation divides vapor to be precipitated is collected by the catch basin below flue gas condensing heat exchanger, plays water-saving effect；This reality
Modular mode is used with novel entirety, convenient for equipment installation and trouble hunting.
