Technical field
The utility model relates to a kind of gathering-device of flue gas purification system, belongs to power industry field of environment protection.
Background technology
According to statistics, the coal-burning power plant more than 95% of China adopts electrostatic precipitator.As everyone knows, under accidental conditions, efficiency of dust collection can reach 99%, but very limited for fine grained flue dust removal ability.The fine droplets of fine grained flue dust and a small amount of slurry spraying after wet desulfuration tower, uses existing demister can not catch at all, and enters clean flue and chimney with flue gas; Part is converted into aerosol containing in ultra-fine slurries droplet transition process or is condensed into large droplet, after smoke stack emission, form " white cigarette ", and even near plant area, sedimentation forms " gypsum rain ", brings adverse effect also to periphery ecological environment and resident living.Coal fired power plant flue gas advanced purification technology effectively can solve the difficult problems such as the flue dust perplexing power plant is not up to standard, gypsum rain, sulfur trioxide, sulfur dioxide, nitrogen oxide and ammonia etc. are comprised to precursor pollutant and heavy metal Hg has Collaborative Control effect simultaneously, have important practical significance.
Wet electrical dust precipitator dust-cleaning principle and dry collector dust-cleaning principle similar, the object that wet static dedusting removes is made up of dust and droplet, because the physical characteristic of droplet and dust exists difference, its operation principle also difference to some extent.For the flue gas of water vapour content and high fume temperature, more existing treatment systems can arrange cool solidifying heat exchanger and be used for recovered flue gas heat, but all do not provide a kind of effective gathering-device for the flue gas after heat exchange and condensed water.In addition, relate to water rinse-system in wet static dedusting technology, it is one of hot subject of this area research that the aqueous vapor after how collecting desulfurization in wet flue gas rinses water source as wet static dedusting device automatic on-line.Existing on-line rinsing water source is mainly derived from the public fresh water (FW) system of power plant, adds public fresh water (FW) system water consumption on the one hand; In addition on the one hand, due to distant for water system distance gas cleaning gathering-device, long-distance sand transport adds lectotype selection surplus and investment, is unfavorable for investment reduction cost.
Summary of the invention
The purpose of this utility model is the gathering-device in order to provide a kind of flue gas purification system, effectively can collect water in flue gas as on-line rinsing system water source, improve dust removal performance, achieves the object that automatic on-line rinses.
The concrete technical scheme that the utility model adopts is as follows:
A kind of gathering-device of flue gas purification system, flue gas purification system inside is disposed with condensing heat exchanger, gathering-device, automatic on-line rinse-system, cathod system, rigidity fine particle anode dust collecting system and collecting tank according to flow of flue gas direction, collecting tank is arranged on the bottom of cleaning system, described gathering-device comprise connect successively concavo-convex porous collection groove, collect liquid storage tank, delivery pump and valve, feeder be arranged on condensing heat exchanger outlet below; Described concavo-convex porous collection groove is pyramid type, and the swash plate surface of feeder is concaveconvex structure, and protruding top arranges flue gas water conservancy diversion through hole; Described valve is connected to the water inlet pipe of automatic on-line rinse-system by pipeline.
Further, the outlet of described feeder is connected with collection liquid storage tank by the water pipe with certain angle of inclination.
Described rigidity fine particle anode dust collecting system comprises rigidity dust collection plate and brace summer, and brace summer is positioned at below rigidity dust collection plate, and is welded on flue gas purification system body.
Further, described rigidity dust collection plate is that ladder is arranged, and its material is stainless steel, fiberglass or fabric.
The utility model utilizes the feeder of special construction, is originated by the water collected, realize automatic on-line pre-washing function as the rinse-system water of wet electrostatic device.Utilize feeder collection condensing heat exchanger to coagulate the water of change, make automatic on-line rinse-system and fine grained trapping system form a binary cycle system on the one hand, both relatively independent operations; On the one hand be arranged in again in same device in addition, both ensure that fine grained arresting efficiency higher, again reduce water consumption, decrease occupation of land, saved investment and operating cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of flue gas purification system of the utility model;
Fig. 2 is the detail of construction of the concavo-convex porous collection groove of the utility model.
In figure: the former flue gas of 1-, 2-neat stress, 3-condensing heat exchanger, 4-cathod system, 5-rigidity fine particle anode dust collection plate, 6-collecting tank, the clean flue of 7-, 8-automatic on-line flusher, the concavo-convex porous collection groove of 9-, 10-collects liquid storage tank, 11-delivery pump, 12-valve, 13-flue gas water conservancy diversion through hole, 14-feeder swash plate, 15-collects liquid pipeline.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figure 1, be flue gas purification system that the present embodiment is used.Condensing heat exchanger 3 is fixedly installed on the smoke inlet place of flue gas purification system, and former flue gas 1 enters condensing heat exchanger 3, collects the steam of condensing heat exchanger cohesion as the water source of automatic on-line flusher 8, achieve the object of water saving by gathering-device.The flue gas water conservancy diversion through hole 13 that flue gas is arranged above by concavo-convex porous collection groove 9 improves air flow method, then by rigidity fine particle anode dust collection plate 5, in rigidity fine particle anode dust collection plate 5, the cathode line be connected with cathod system 4 is discharged, make the fine particles such as the water droplet in flue gas, flue dust charged, under the effect of electric field force, anode moves, trapped by rigidity fine particle anode dust collection plate 5 by electrostatic force, collecting tank 6 collects water droplet and the flue dust of the trapping of rigidity fine particle gathering-device, and neat stress 2 passes through clean flue 7 by chimney qualified discharge.Cathod system 4 mainly comprises cathode line, the erecting by overhang of top and the bottom, insulated case.
