Abstract
The utility model is an emulsion preparation equipment for lime powder including a preparation case, an liquidometer, a stirrer, an anti plugging cover, a lime powder measuring hopper, upper and lower pneumatic board plug valves, a blanking pipe, a lime material storehouse, an exhaust pipe, an emulsion outlet valve and a water inlet valve. A large-angle spray nozzle is connected through a spraying water valve. A water case, used specially for assimilation reaction, connected to the preparation case is arranged when the charge is raw lime powder. The emulsion assimilating preparation equipment for lime powder adopts high temperature digestion (90-100 Degree Celsius), which not only promotes assimilation reaction process but also enable the milk of lime to have high dispersion. A blast aeration valve preventing dewing and bonding on pipe wall is arranged outside the blanking pipe, little hot air is blew in (or a heating equipment is arranged on the blanking pipe) by the control of the valve then dewing and bonding on pipe wall are prevented. The equipment may not only improves the emulsion dispersion, reduces the bonding on inner wall, but also prevents jams in the blanking pipe, then safety running of emulsion preparation equipment is ensured.
Description
Technical field
The utility model relates to the improvement of the water demineralization treatment facility in the city sewage deep treatment engineering, specifically is a kind of lime powder emulsion preparation equipment, and it also is applied to other industrial production of using milk of lime.
Background technology
In water or advanced treatment of wastewater technical field, the lime treatment method is a kind of not only economy but also good method free from environmental pollution.Be extensive use of the lime treatment method at home and abroad as far back as the fifties, particularly municipal effluent is the main decision-making that China alleviates the Freshwater resources scarcity as the water source of the master of power plant process water in recent years.According to the water quality characteristics of Chinese northern area, generally speaking, the advanced treatment of municipal effluent after second-stage treatment all preferentially adopts the lime treatment method.Thus, the research and development of the equipment of newborn equipment of calcium lime powder digestion system and slaked lime powder system breast are important topics in the lime treatment method device systems in the water demineralization treatment facility.
What the newborn technology of the system of calcium lime powder digestion at present was commonly used is low-temperature digestion system breast, be that calcium lime powder is directly sent in the big water gaging, stir the system breast, because the characteristics of calcium lime powder own, it can produce a large amount of conglobulation things in water when meeting water digestion, its surface is gelationus slaked lime [Ca (OH)
2].This ball centre then is the calcium lime powder of dried shape, because the gluey film that gelationus slaked lime seals in the outside formation of spheroid, its outside water infiltrates this spheroid inside, then needs the long time.Therefore, the churning time of low-temperature digestion system breast process is longer, is easy to cause the obstruction of follow-up system and equipment.In equipment, produce a large amount of flying dusts during again owing to blanking, on this its upper side wall, vapor pipe and blanking tube wall, produce a large amount of adhesive easily, so that the safe operation of newborn equipment is made in influence.The milk of lime dosing apparatus of slaked lime powder equally also can be on its its upper side wall, and vapor pipe and tremie pipe will produce the adhesive of a large amount of slaked limes after operation for some time, also can influence the safe operation of the newborn equipment of system.
Summary of the invention
Deficiency at above-mentioned calcium lime powder digestion newborn equipment of system and slaked lime powder milk of lime dosing apparatus, goal of the invention is in order to ensure the safety and economic operation of the newborn equipment of system, calcium lime powder digestion system breast and two kinds of equipment of slaked lime powder system breast have been proposed to be respectively applied for, these two kinds of devices can improve emulsion dispersion, significantly reduce device inwall adhesive, can stop the obstruction of tremie pipe again, ensure the safe operation of the newborn equipment of system.
Task of the present utility model is finished by following technical scheme, developed a kind of lime powder system breast device, it is the system breast device that into feeds intake with lime powder, it comprises: preparation case (jar) body and liquidometer thereof, agitator and Anti-stop cover, lime powder weighing hopper and upper and lower pneumatic push-pull valve thereof, tremie pipe, the lime feed bin, vapor pipe, slurry outlet valve and inlet channel and water intaking valve thereof.Also be provided with the spray water valve on suction culvert, this spray water valve has by pipe connection: be arranged on intravital, the uniform wide-angle nozzle of this case (jar).
Described preparation case (jar) body, when its with calcium lime powder when advancing to feed intake, prepare the setting of case (jar) body for this and specialize in digestion water tank and the liquidometer thereof that digestion reaction is used, this digestion water tank is connected and is gone into to prepare case (jar) body by pipeline and digestion water intaking valve thereof.
Described lime powder weighing hopper, it is: the calcium lime powder weighing hopper of the newborn device of calcium lime powder digestion system; Itself or be the slaked lime powder weighing hopper of slaked lime powder system breast device.
Described lime powder weighing hopper is provided with on the tube wall of its blanking pipeline and prevents tube wall dewfall agglutinating air blast valve, or at the tremie pipe outer wall companion's thermic devices is set.
Described air blast valve also is provided with the well heater of heating air blast on the pipeline between itself and the blanking pipeline.
Advantage of the present utility model is: because the newborn device of the calcium lime powder of the utility model design digestion system adopts thermophilic digestion (90-100 ℃), can the promoting digestion reaction process, and can make the milk of lime of preparation have polymolecularity again.
Its operation of equipment mode is:
The water that adds is to control its flooding quantity by the liquid level of digestion water tank for the first time, and the weight ratio of its flooding quantity and calcium lime powder is 3: 1, mixes.Carry out digestion reaction this moment, and the reaction of water and calcium lime powder is an exothermic process, and its thermal discharge can make the temperature of reaction mixture be elevated to 90-100 ℃.This is swift in response and finishes (general 2-5 minute), can form slaked lime [Ca (OH)
2] mashed prod.
Adding for the second time water is to control its flooding quantity by the liquid level in the preparation case, is mixed with needed lime milk concentration.In order to prevent that the calcium lime powder that waves in the case when the charging is bonded in casing top, vapor pipe and the tremie pipe, after tremie pipe charging (about 5 seconds) is finished, open the wide-angle nozzles spray that water inlet pipe connects, utilize and be located at casing top wide-angle nozzle, the dust that flies upward is removed.In order to prevent tremie pipe because bonding produce to be stopped up, in tremie pipe, prevent tube wall dewfall agglutinating air blast valve by setting, blast a spot of warm air (or establish companion thermic devices at the tremie pipe outer wall) continuously by this valve control, prevent that blanking tube wall dewfall from causing bonding.Ensured the normal operation of system breast.
The device of the slaked lime powder preparing lime milk close with the structure of the newborn device of above-mentioned calcium lime powder digestion system, the wide-angle nozzles spray equally also is set, it can prevent effectively that also slaked lime powder from producing bonding in casing or tank body top, tremie pipe or vapor pipe, ensured the normal use of equipment.Be the disposable milk of lime that water is mixed with desired concn that adds this moment, needn't pass through the digestion reaction process.
