Technical field
The present invention relates to the processing technology field of combustion product, more particularly, is a kind of desulfurized dust collector with multiple water films.
Background technology
Existing flue gas desulfurization (FGD) is control SO
2The major technique means of polluting mainly are to utilize the absorbent of various alkalescence or the SO in the adsorbent capture flue gas
2, fume desulphurization method mainly contains following three kinds: (1) dry method, with powdery or granular absorbent, adsorbent or catalyst to remove SO
2(2) wet method promptly adopts the liquid-absorbant washing to remove SO
2(3) semidry method, absorbent desulfurization and processing desulfurization product carry out under wet state and drying regime respectively.Wherein wet washing is occupied an leading position, and accounts for 85%.
Existing flue gas ash removal mainly adopts modes such as bag-type dusting, mechanical type dedusting, electric precipitation and wet dedusting; The at present domestic dust arresters such as cloth-bag type, cyclone type, electrostatic, water film type, fountain and water-bath type that utilize carry out flue gas ash removal.Cloth-bag type, cyclone type and electrostatic dust arrester only have dedusting function, and middle pernicious gas can not remove smoke; Water film type, fountain and water-bath type belong to Wet-way dust-collector, and it has the dual-use function of dedusting, filtering noxious gas, still, the existing water film type device that is suitable for flue gas desulfurization and dedusting, because complex structure, the cost height can only be used for newly-built large power plant usually and use.Though and middle-size and small-size industry coal-boiler is to cause dust and SO
2One of important source of polluting, and the existing supporting cleaner function singleness of middle-size and small-size industry coal-boiler, efficiency of dust collection is generally lower and be unsuitable for desulfurization, can not satisfy the environmental requirement that improves day by day.
Summary of the invention
Technical problem to be solved by this invention is, prior art is improved, and it is one that a kind of collection desulfurization and dedusting function are provided, rational in infrastructure, desulfurization dust-removing efficiency height, effective satisfies environmental requirement, is particularly suitable for the matching used desulfurized dust collector with multiple water films of middle-size and small-size industry coal-boiler.
Solving the technical scheme that its technical problem adopts is, a kind of desulfurized dust collector with multiple water films, it comprises body 10, at body 10 sidewalls gas approach 1 is set tangentially, purification exhanst gas outlet 5 is set at body 10 tops, in body 10, be provided with water desulfurizing-dusting device 11, the structure of described water desulfurizing-dusting device 11 is, the outside sandwich 14 that between tube 12, forms that body 10 and body 10 are built-in, every tube 12 and the intermediate course 15 and the central tube 13 that form every the built-in central tube 13 of tube 12, outside sandwich 14, intermediate course 15 and central tube 13 are connected, at outside sandwich 14, intermediate course 15 and central tube 13 tops are provided with ring-type moisture film generator 2, top in body 10 be provided with communicate with the central tube 13 of water desulfurizing-dusting device 11 take off mist dehumidifier 16, describedly take off the conically shaped of one deck at least I3 that mist dehumidifier 16 comprises that the tops in the body 10 are provided with, take off mist dehumidifier 16 and be communicated with purification exhanst gas outlet 5.
Described water desulfurizing-dusting device 11 also is included in described intermediate course 15 and the central tube 13 lamination that all the is provided with formula eddy flow guide plate 9 of misunderstanding each other.
Purification exhanst gas outlet 5 places on described body 10 tops are provided with flue-gas temperature monitoring point 6.
On described body 10 tops, take off mist dehumidifier 16 places sulfur dioxide monitoring point 7 be set.
Described body 10 tops be positioned at take off mist dehumidifier 16 places and/or body 10 bottoms be positioned at the flue dust outlet above acid-base value monitoring point 8 is set.
The advantage applies of desulfurized dust collector with multiple water films of the present invention exists:
(1) because employing tangentially is provided with gas approach on the body sidewall, the flue gas eddy flow is entered in the body, enter intrinsic eddy flow flue gas, detour and the abundant drip washing of ring-type moisture film generator through the misunderstand each other break-in baffling of formula eddy flow guide plate of outside sandwich, intermediate course, central tube and the lamination of the built-in water desulfurizing-dusting device of body, the mist dehumidifier that takes off that constitutes through the taper guide shell dewaters again, cause the purification flue gas of desulfurization and dedusting to be discharged from purifying exhanst gas outlet, it is rational in infrastructure, desulfurization dust-removing efficiency height, effective and satisfy environmental requirement.
(2) because collection desulfurization and dedusting function are one, utilize a covering device just can solve the needs of medium small boiler dedusting simultaneously, desulfurization, cost is low.
(3) owing to be provided with flue-gas temperature monitoring point, sulfur dioxide monitoring point, acid-base value monitoring point, can realize exhanst gas outlet temperature, sulfur dioxide and acid-base value are monitored in real time, strict control cleaning solution is in the acid-base value and the exhanst gas outlet temperature of deduster entrance and exit.Both can control the quality of desulfurization and dedusting, also save cleaning solution simultaneously.
