Description

Integrated high-efficiency desulfurization and dedusting demister
Technical field
The utility model belongs to coal fired power plant flue gas desulfurization, dedusting, demist technical field, is specifically related to a kind of integrated high-efficiency desulfurization and dedusting demister.
Background technology
Rich coal resources in China, coal is widely used in the technical fields such as generating, heating, metallurgy as fuel, cause thus the discharge capacity of China's sulfur dioxide huge, and atmosphere has been caused to serious pollution.China is that global SO2 emissions are the highest at present, one of acid rain area maximum, country that problem is the most outstanding, urgently to be resolved hurrily.
Flue gas desulfurization technique can be divided into three kinds of dry method, semidry method and wet methods, wet process of FGD is to adopt the gas liquid reaction of liquid-absorbant under ion condition, and then sulfur dioxide in removal flue gas, system device therefor is simple, stable and reliable operation, desulfuration efficiency is high, is current industrial trade large-scale application, effective sulfur method.Traditional removing sulfur, dust and fog from flue gas equipment by horizontal Venturi tube, organize sparge pipe, main tower and centrifugal separating device more and form, this equipment is owing to limit by its structure, after there is desulfurization, clean exhaust gases passes mouth flue gas is containing ash, band mist, it is bad that dedusting removes fog effect, desulfuration efficiency is lower, floor space is larger, the problem that engineering construction cost is high.
Summary of the invention
The utility model is to solve the problems referred to above that prior art exists, a kind of integrated high-efficiency desulfurization and dedusting demister is provided, desulfurization and dedusting demist efficiency has a more substantial increase, and removal effect is better, and integrated structural design has reduced floor space and construction cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of integrated high-efficiency desulfurization and dedusting demister, comprise clean exhaust gases passes after exhaust gases passes before desulfuration absorbing tower, desulfurization, desulfurization, before described desulfurization, exhaust gases passes is arranged on desulfuration absorbing tower lower sides, after described desulfurization, clean exhaust gases passes is arranged on desulfuration absorbing tower top, and before the inner desulfurization of described desulfuration absorbing tower, after exhaust gases passes and desulfurization, the part between clean exhaust gases passes is installed with spraying layer, one-level demister layer, Venturi tube layer, shower humidification layer, secondary demister layer, three grades of demister layers from bottom to top successively; Described spraying layer is provided with some row of horizontal spray equipments; Described one-level to a three grade demister layer is horizontal demister or ridge type demister; Described Venturi tube layer is the structure that the anti-corrosive steel tube that gathered by some rows forms; Described shower humidification layer is the damping device that some (operating) water nozzles are installed.
Integrated high-efficiency desulfurization and dedusting demister described in the utility model, its beneficial effect is:
1, demister layer, the integrated design of Venturi tube layer are built, two class device layers are strengthened mutually, both can meet the requirement that in flue gas after desulfurization, water smoke is removed, can meet again the grit of carrying secretly in flue gas after desulfurization, the requirement that foundry loam is removed, and make demist, efficiency of dust collection have raising by a relatively large margin, particularly remove efficiently PM2.5 grit and the foundry loam in flue gas after desulfurization, carried secretly.
2, the uniform flue gas of Venturi tube layer, the contact of enhancing gas-liquid-solid three-phase, together with shower humidification layer, have desulfurizing function again to the flue gas after the effect of spraying layer lime stone slurry, thereby improved desulfuration efficiency.
3, the subparticle in the adsorbable flue gas of water smoke of shower humidification layer ejection, promotes gathering, the removal of dust subparticle.
4, integrated design, compact conformation, floor space reduces, engineering construction cost.
