Description
Technical field
The utility model relates to industrial tail gas process field, is specifically related to a kind of Spraying Dryer of Ceramics exhaust treatment system.
Background technology
Increasing along with China's architectural pottery output, dust and the waste gas of discharge also constantly increase, and in order to prevent causing environmental pollution in these dust and toxic emission to air, need to take rational means to process these dust and waste gas.At present, at ceramic production industry, spray drying tower is the required equipment preparing ceramic powder, and the dust produced by it and waste gas sulfur dioxide are also the main sources of ceramic production industry pollutant emission.
In order to solve the emission problem of dust and waste gas sulfur dioxide in Production of Ceramics process, in recent years, some Production of Ceramics producers of China start to be applied in by sack cleaner on spray drying tower, concrete solution is that the dust-filtering that first will be produced in spray drying tower by sack cleaner is removed, by the mode of wet desulphurization, sulfur dioxide is removed afterwards, wherein sack cleaner is by being installed on the Bag filter dust on orifice plate, realizes reverse gas cleaning by back-blowing device.Adopt above-mentioned first dust removal by filtration, the method of rear wet desulphurization achieves certain effect really, but, applicant in use notices: sack cleaner filtering accuracy after using 3-4 month significantly declines, there is the situation of dust exceeding in the tail gas after filtration, in addition because the dust of discharging from spray drying tower and exhaust temperature fluctuations strengthen, its fluctuation range is at 80 DEG C-260 DEG C, but the filter material forming cloth bag in sack cleaner mostly is and weaves filter material, fiber cotton for wadding filter material, overlay film filter material, glass fiber filter etc., the maximum temperature that these filter materials can tolerate 130 DEG C only, work under cloth bag being placed in said temperature scope after a period of time and burning bag phenomenon very easily occurs, the dust bonding filtering interception is difficult to cleaning on cloth bag.In order to ensure the operating efficiency of sack cleaner, needing the cloth bag constantly changed in deduster, needing to carry out workshop parking when changing cloth bag, the expense changing cloth bag adds that the economic loss caused of stopping makes the production cost of ceramic producer greatly increase.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of vent gas treatment effect better and the Spraying Dryer of Ceramics exhaust treatment system that production cost is lower.
In order to solve the problems of the technologies described above, the utility model realizes by the following technical solutions:
The utility model Spraying Dryer of Ceramics exhaust treatment system comprises the deduster be connected with Spraying Dryer of Ceramics tail gas output channel and the desulphurization system be connected with deduster filtering gas output channel, the described output channel of filtering gas is provided with blower fan, the orifice plate that described deduster inside is provided with filter core and installs for filter core, described filter core is the metal filter bag of all face closures of one end open that flexible, porous metal forming is formed.From Spraying Dryer of Ceramics, tail gas out mainly comprises some harmful dust and waste gas sulfur dioxide, tail gas enters in deduster along conveyance conduit, the dust in tail gas is fallen in the filter core interception be arranged in deduster, the gas making dust content less sends into desulphurization system through deduster filtering gas conveyance conduit, in desulphurization system, generally adopt wet desulphurization, complete the process to Spraying Dryer of Ceramics tail gas thus.The deduster of flexible, porous metal forming is wherein adopted to filter the benefit that the tail gas containing dust and waste gas sulfur dioxide has two aspects, on the one hand the working strength of flexible, porous metal forming and filtering accuracy comparatively weave filter material, fiber cotton for wadding filter material, overlay film filter material, glass fiber filter are high, the applicant is proven, when other condition is identical, the filtration flux of its filter core formed is about the twice of the Bag filter flux that above-mentioned filter material is formed, and vent gas treatment effect is significantly improved; The physical property of flexible, porous metal forming determines that the metal filter bag that it is formed is more high temperature resistant compared to existing cloth bag on the other hand, therefore the filter bag generation burning bag phenomenon that high-temperature gas out can not make it form from Spraying Dryer of Ceramics, longer service life, do not need often to change filter bag again, greatly reduce production cost.
