Abstract
The utility model discloses an integrated device for dust-removal, desulfurization, denitration and heating, which belongs to the technology of exhaust gas pollution abatement and is mainly used to desulfurize (denitrate) and remove the dust of an industrial boiler and a furnace as well as all coal-fired smoke gases and industrial dust. The overall shape of the device is round inside and square outside, and the inner surface of the device is coated with an antiseptic and wearproof protection layer. The device adopts the technical proposal that the exhaust gas flows orderly through an inlet, a heater, a multilevel cyclone dust-removing cylinder, a multilevel pipe for spraying, watering, desulfurizing, and denitrating, a large-caliber dewatering and demisting cylinder one by one and then again enters in the heater and the outlet, so that the sulfur dioxide, the nitrogen oxide, and other harmful gases in the smoke gas can be got rid of by fully reacting with desulfurizer (denitration reagent), and then the smoke gas enters into the heater so as to heat the smoke above the dew point. The device has the advantages that the integration of dust removal, desulfurization, denitration, dewatering, demisting, and heating is realized, the efficiencies are respectively as follows: the dust removal coefficient is 99.8 percent, the desulfurization coefficient is 98.6 percent, the denitration coefficient is 88.7 percent; the device has less resistance, the smoke gas does not carry water and does not deposit dust, and the operational cost is low.
Description
Affiliated technical field
The utility model relates to a kind of dust-removal and desulfurizing denitration intensification integrated apparatus, is used for the dust-removal and desulfurizing denitration and the industrialness elimination of dust contamination of Industrial Boiler, kiln waste gas.
Background technology
In recent years, along with the development of industrial production and city civilization construction, the harm understanding that people's environmental pollution is caused is more and more clear, administers, protects environment requirement and desire more and more higher.In order to reduce discharge of harmful gases amount in the flue gas, the prior art measure is the terminal configuration of the back-end ductwork one dust-removal and desulfurizing equipment at boiler or kiln, form owing to piling up with natural granite, cohering seam when handling high-temperature flue gas usually splits and leaks gas and leak, device therefor does not have flue gas heating measure again, and the flue gas after wet-treating is with water easily, causes the problems such as stifled ash, dust stratification and corrosion of air-introduced machine, chimney and flue, though can remove a large amount of flue dust, desulfurization (SO
X), denitration (NO
X) effect still can not reach the standard of environmental regulations.
The technical problem that solves
Exploitation purpose of the present utility model is to develop a kind of flue gas of administering after qualified that can make and overcomes the defective of above-mentioned prior art, but also to solve leak, stifled ash, not dust stratification, not with problems such as water and corrosion except that desulfuring and denitrifying apparatus.
The utility model content
The whole arrangement (with reference to accompanying drawing 1,2) of making of the utility model, the housing material therefor can adopt metal material or construction material, adopts disposable construction to be shaped as interior garden foreign side, inside lining anti-corrosive wear-resistant protective layer.High-temperature flue gas is introduced into heater (2) outer tube by import (1), and flue gas is walked from top to bottom, and then flue gas enters multistage cyclone dedusting tube (3), and after the thick dedusting of multistage cyclone dedusting tube, flue gas is walked from the bottom up; Flue gas is sent in the multilayer spraying spray desulphurization denitration pipe (4), flue gas is walked from top to bottom, utilize jet pipe and nozzle (5) to be installed in the advantage in multilayer spraying spray desulphurization denitration pipe (4) centre, liquid with desulfurization (nitre) agent sprays in the interior rotation flue gas of multilayer spraying spray desulphurization denitration pipe (4) at many levels, make air water fully contact micronic dust and be condensed into larger particles, make pernicious gas such as sulfur in smoke and nitrogen oxide and desulfurization (nitre) agent etc. fully reaction remove, under action of centrifugal force flue gas and dirt moisture from, flow out dust-removal and desulfurizing denitration intensification integrated apparatus from outlet pipe (6); The qualified flue gas of treated mistake is sent in the heavy caliber dehydrating demisting tube (7) by multilayer spraying spray desulphurization denitration pipe (4) again and is removed aqueous vapor and fog, and flue gas is walked from the bottom up; Through the qualified flue gas that dehydrating demisting was handled, sent back to pipe in the heater (2) once more, low-temperature flue gas is heated to more than the dew point, thereby has solved corrosion and the dust stratification problem of low-temperature flue gas flue and air-introduced machine; After the qualified flue gas that heats and handled is sent dust-removal and desulfurizing denitration intensification integrated apparatus from outlet (8).
Beneficial effect
The utility model dust-removal and desulfurizing denitration intensification integrated apparatus, compare with existing dust-removal and desulfurizing equipment, can make the flue gas that removes after qualified overcome the defective of above-mentioned existing equipment and technology, and well solve leak, stifled grey, problem such as dust stratification and corrosion not, and have dust removal efficiency 99.8%, desulfurization degree 98.6%, denitration rate 88.7%; Device resistance is little, flue gas is with water, low etc. characteristics of dust stratification, operating cost not.
The specific embodiment
Specific embodiments of the present utility model is an overall structure with metal material or construction material manufacturing, and global shape is an interior garden foreign side, the inside lining anti-corrosive wear-resistant protective layer.Governance process be make the untreated flue gas heater via (2) that enters dust-removal and desulfurizing denitration intensification integrated apparatus, multistage cyclone dedusting tube (3), multilayer spraying spray desulphurization denitration pipe (4), heavy caliber dehydrating demisting tube (7), again advance the efficient processing of heater processes such as (2) after.Flue gas reaches the requirement of qualified discharging, discharges dust-removal and desulfurizing denitration intensification integrated apparatus.
