Abstract
The invention discloses a kind of white systems that disappears suitable for alkali kiln gas, are made of gas cooler, heat recovery heat exchanger, spray column, spray column water pump, flue gas heater, cooling tower.After flue gas enters gas cooler cooling, into heat recovery heat exchanger reducing temperature twice, enters spray column cool-down dehumidification later, finally discharged after flue gas heater heats up.Flue gas thoroughly eliminates white cigarette to remove the most of moisture and salt in flue gas by two-stage cooling, spraying cooling dehumidifying, heat temperature raising；The heat of waste heat recycling has carried out sufficient utilization, spraying cooling water and cooling-tower circulating water and has been exchanged heat by heat exchanger, ensure that the water quality of cooling-tower circulating water, improves economic benefit, reduces pollution on the environment.
Description
Technical field
The present invention relates to field of environment engineering technology, especially a kind of white system that disappears suitable for alkali kiln gas.
Technical background
Flue gas disappears white meaning, has been known together in recent years, largely the drop containing salt can be discharged with wet flue gas
Into atmosphere, wherein the sol particle object carried, exerts a certain influence to environment.Alkali kiln gas water content is high, wet cigarette
Plumage is more serious, it is therefore desirable to take the white measure that disappears accordingly.
This patent disappears white for the flue gas of alkali furnace, provides a kind of feasible effective measures.
Summary of the invention
The present invention is a kind of white system that disappears suitable for alkali kiln gas, can carry out two-stage cooling, spraying cooling to flue gas
Dehumidifying, heat temperature raising thoroughly eliminate white cigarette to remove the most of moisture and salt in flue gas.
To achieve the above object, technical solution of the invention are as follows: it is a kind of suitable for alkali kiln gas disappear white system by
Gas cooler, heat recovery heat exchanger, spray column, spray column water pump, flue gas heater, cooling tower composition.Flue gas enters cigarette
After Gas Cooler cooling, into heat recovery heat exchanger reducing temperature twice, enters spray column cool-down dehumidification later, finally pass through flue gas
It is discharged after heater heating.
It is further described that carrying out heat transfer with heat medium water circulation between gas cooler and flue gas heater.
It is further described that spray column recirculated water and cooling-tower circulating water are exchanged heat using heat exchanger.
It is further described that the heat process water of heat recovery heat exchanger recycling is sent to other workshops, process water is derived from
Cooling tower.
The beneficial effects of the present invention are: flue gas dehumidifies by two-stage cooling, spraying cooling, heat temperature raising, to remove cigarette
Most of moisture and salt in gas, thoroughly eliminate white cigarette；The heat of waste heat recycling has carried out sufficient utilization, spraying cooling water
It is exchanged heat with cooling-tower circulating water by heat exchanger, ensure that the water quality of cooling-tower circulating water, improve economic benefit, reduce pair
It is polluted caused by environment.
Detailed description of the invention
Invention invention is further described with reference to the accompanying drawings and detailed description.
Attached drawing 1 is that a kind of flue gas suitable for alkali furnace disappears white system schematic.
In figure: 1, gas cooler, 2, heat recovery heat exchanger, 3, spray column, 4, heat exchanger, 5, spray column water pump,
6, flue gas heater, 7, cooling tower.
Specific embodiment
As shown in attached drawing, it is a kind of suitable for alkali kiln gas disappear white system by gas cooler 1, heat recovery heat exchanger 2,
Spray column 3, heat exchanger 4, spray column water pump 5, flue gas heater 6, cooling tower 7 form.
When the white system that disappears is run, flue gas enters gas cooler 1 and carries out level-one cooling, recycles and exchanges heat then into waste heat
Device 2 carries out second level cooling, and flue gas continues to flow, and into 3 cool-down dehumidification of spray column, flue gas enters the heating of flue gas heater 6 later
After be discharged；The heat that heat recovery heat exchanger 2 absorbs flue gas is used for heating process water, and process water is derived from cooling tower 7, after heating
Process water send to other process for needing hot water；4 cold source of heat exchanger comes from cooling-tower circulating water, the extraction spray of spray column water pump 5
Working medium in leaching tower sprays Hui Tazhong after heat exchanger 4 is cooling, is recycled.
The above, embodiment is only that preferred embodiments of the present invention will be described, not to of the invention
Range is defined, and under the premise of not departing from the spirit of the technology of the present invention, this field engineers and technicians are to skill of the invention
The various changes and improvements that art scheme is made, should fall within the scope of protection determined by the claims of the present invention.
