Description
Technical field
The present invention relates to a kind of device of lime metering method, relate in particular to a kind of shunt regulating lime milk dosing system, it is particularly suitable for the lime medicine system in intermediate water reuse system, Water Treatment in Circulating Cooling System, desulfurization wastewater treatment system etc.
Background technology
The lime metering system adopted in power plant chemistry process Hydraulic Projects at present has two kinds, dry method and wet process metering system.To be employing system inflow size and dry lime dosage according to certain ratio add lime dry method measuring principle ensures that PH stablizes in depositing reservoir below, specifically comprising equipment is: lime bin, vibrating bunker, hand operated gate valve, star-shaped feeding machine, conveying worm, gas powder separator, balanced reservoir, lime under agitation case, Lime Milk Transfer Pump, also comprise mating valve and control instrument, control cabinet, mixer etc.The technological process of its metering method: the star-shaped feeding machine of dry method metering is VFC, according to system inflow size, the frequency-variable controller adjustment discharge quantity of adjustment star-shaped feeding machine realizes Systematical control index.Concrete milk of lime manner of formulation is, the blanking of feed bin cone bucket, arch camber is prevented to vibrating bunker, guarantee blanking is unobstructed, lime enters star-shaped feeding machine, is metered into conveying worm by frequency conversion, and lime is sent into lime preparation case by gas powder separator by conveying worm, the water inlet of preparation case is communicated with from flowing into agitator tank by balanced reservoir with agitator tank, ensures that in agitator tank, liquid level is constant.Delivery pump is power frequency conveying milk of lime, because lime milk concentration difference adjustment Lime-Injecting amount ensures equipment pH value below.This metering method greatest problem is that lime system easily blocks, and pipeline and delivery pump often block, and star-shaped feeding machine often blocks, and leaks powder serious, because vibrating bunker is outer vibration, cause blanking place poorly sealed, cause severe air to pollute in workshop.Maintenance workload is very large, all will take pump, pipeline, star-shaped feeding machine cleaning every day apart, remove blocking.Air pollution cannot be avoided, and also cannot process.The problem caused is more serious.Current part factory also in employing, but is all run in spite of illness.Be badly in need of transforming as early as possible.
Limewash method metering system comprises equipment: lime bin, shake reach motor, hand operated gate valve, lime weighing hopper (being with pneumatic insertion plate door), weighing hopper outlet Pneumatic butterfly valve, lime preparation case, lime under agitation case, Lime Milk Transfer Pump, lime milk metering pump, hydrocyclone, also comprise mating valve and control instrument, control cabinet, 2, mixer etc.The technological process of its metering method: wet method metering method measuring pump is VFC, realizes chemical feeding quantity by measuring pump change of frequency and changes with the change of system inflow, ensure that system PH is constant below.Lime bin sodalime reaches motor and shakes to reach and enter lime weighing hopper by shaking, in weighing hopper after the full quantitative lime of storage, it is grey under in lime preparation case, after water inlet to certain liquid level and volume, ash output valve opened by weighing hopper, dissolving object is reached by being uniformly mixed, be transported to by Lime Milk Transfer Pump after dissolving and catch husky device, remove inner sand, enter milk of lime agitator tank, in agitator tank, dissolve mixing further, be transported to system below by lime milk metering pump.Better but also have problems, problem mainly contains native system operational effect: 1, weighing hopper also easily blocks, and especially during initial stage blanking, vibrating motor vibrating effect is poor, is difficult to blanking.2, integral device cost is higher, and valve and equipment are all more, because of needs with preparation case according to volume measurement, comparatively large by what calculate that preparation case and agitator tank will do, highly higher, cause workshop total height higher, project total cost is higher.Overall operation effectiveness comparison is good, and do not leak grey problem, air pollution is little.Blockage problem is less, because lime inferior quality easily causes pipeline and system jams.Repair rate is slightly low.Greatest problem is that cost is high.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is, provide a kind of shunt regulating lime milk dosing system, pipeline and valve not easily block, and can not leak grey phenomenon; Can be good at ensureing that the compound concentration of milk of lime, cost are low simultaneously.
