Description

A kind of waste water treatment system, multichannel process system and multi-level handling system
Technical field
The utility model is related to a kind of waste water treatment system, multichannel process system and multi-level handling systems, belong to firepower hair Electric technical field of waste water processing.
Background technology
The wastewater treatment of coal-fired station mainly has steam multiple-effect evaporation, membrane process+MVC/MVR evaporations+crystallization, cigarette Road evaporation, membrane distillation (MD) technology etc..By taking the thermal power plant of 2 × 600MW grades as an example, power plant's about 20 tons of wastewater flow rate of production/when, such as MVC evaporation/crystallization technologies are sprayed using U.S.'s horizontal film, gross investment is 60,000,000 yuan, about 12,000,000 yuan of annual operating cost.It is useless Water treatment facilities investment is high, and operating cost is higher, increases the production cost of electric power enterprise.On the other hand, current waste water Processing equipment failure rate is higher, and service life is shorter, and a set of membrane process+MVC/MVR evaporation equipments are usually run less than 4 years with regard to face The problem of facing replacement membrane element, high expense make most of enterprise can't bear the heavy load.Cost for wastewater treatment how is reduced, and is carried The reliability of high sewage treatment equipment is urgent need to solve the problem in industry.
On the other hand, the deslagging temperature of coal-fired power station boiler is generally up to 600 DEG C or more, this partial heat does not obtain profit With, need additional low-temperature receiver instead and configure slag extractor come realize cooling.Air-cooled slag extractor must largely be passed through cold wind, this part Cold wind enters boiler furnace during cooled slag, forms furnace bottom and leaks out, boiler efficiency is made to reduce about 0.5%.In the market It is badly in need of a kind of new technology, afterheat of slags can be efficiently used, and reduces furnace bottom and leak out loss.
In view of the case where above-mentioned cost for wastewater treatment is high and afterheat of slags is unable to get utilization, existing wastewater treatment system System has and handles waste water using afterheat of slags, such as the waste water treatment system that notification number is CN204897464U, is provided with and firepower Waste water in waste water baffle-box, the warm sludge of slag well is sprayed onto by spray tube by the waste water baffle-box of power-plant waste outlet On, it is intended that by warm sludge waste heat by waste water moisture evaporating completely, while reaching cooling warm sludge purpose.The simple system is practical, but Being that there are problems is:1, the easy fouling of spray tube nozzle, blocking;2, boiler slag removal mouth heating surface high temperature salification corrosion is easily caused;3、 Processing waste water ability is limited, and wet slag problem is more serious.Since wastewater treatment process does not form cyclic process, only waste water is logical It crosses spray tube and sprays to warm sludge, the waste heat by warm sludge is impossible to reach that evaporation is complete, leads to the aqueous height of clinker of output, is needed pair Clinker is dehydrated, and is reprocessed to the waste water of abjection, cost higher.
The technical solution is clearly appreciated that waste water evaporating completely is difficult, therefore in order to keep the waste water energy for entering slag well real Showing evaporating completely, be preferably provided with compressed air unit in the patent document is atomized the waste water that warm sludge is sprayed to from nozzle as possible, but It is that atomization will produce a large amount of salt fog clouds for carrying corrosive ions and drop, boiler slag removal mouth high temperature salification is caused to corrode.
