Abstract
The utility model relates to a new device for calcium chloride to concentrate and dry, adopting two spray drying devices to make into a set of continuous spray drying device capable of both concentrating and drying via scientific connection and integration. The utility model concentrates and dries calcium chloride liquid quickly in atomizing condition, with a view to obtain high-purity, water-free calcium chloride products. The utility model has the advantages of remarkably reducing the concentration and dryness cost of calcium chloride, improving the quality of the products, and alleviating the corrosion of the chloride ion to the device.
Description
Affiliated technical field
Present technique relates to that a kind of Calcium Chloride Powder Anhydrous concentrates, the equipment of drying and calcining process technology, can significantly reduce the manufacturing cost of Calcium Chloride Powder Anhydrous, improves the quality of products, and alleviates the corrosion of chlorion to equipment.
Background technology
Calcium chloride is as a kind of important Inorganic Chemicals, and Application Areas is extensive, is widely used in fields such as industry, agricultural, mining, oil drilling, environment protection, food.
The production method of domestic calcium chloride has three kinds of waste ammonia-soda solution absorption method, hydrochloric acid lime method and Potcrate Greenwaltrecovery process Greenwalt NSCCs.Wherein the waste soda ash solution absorption method is calcium chloride and the sodium-chlor of recycling in the ammonia alkali steaming chlorine waste liquid.Present domestic waste soda ash solution absorption method is produced calcium chloride, and its output accounts for more than 80% of calcium chloride ultimate production.
The calcium chloride product of domestic production is based on two water and anhydrous, and product mostly is sheet or powdery.
After flake calcium chloride production generally adopts the cauldron of weldering system to boil about 70%, enter cylinder cooling pelleter, obtain flake calcium chloride again through packing.After perhaps adopting multiple-effect evaporator to be concentrated to about 70%, enter cylinder cooling pelleter again, obtain flake calcium chloride again through packing.
Calcium chloride powder be with the ammonia alkali evaporated waste ammonia liquid through purification, clarification, evaporation concentration, when calcium chloride content reaches 40% left and right sides, earlier the sodium-chlor Crystallization Separation is come out, salt is made in reprocessing; Mother liquor behind the separation sodium-chlor after further clarifying, enters spray-drier, and drying, packing obtain finished product calcium chloride.
These technology dewatering times are long, and drying efficiency is low, and drying cost is very high, can not continuous production, and throughput is little, and calcium chloride solution residence time in metal vessel is longer, and severe corrosion equipment, contaminated material have reduced the quality of product.According to statistics, the cost of the concentrate drying of solid calcium chloride is about respectively: 300 yuan of main content 74% products, 600 yuan of main content 77% products, main about 1100 yuan/ton of content 94% products (difference being arranged) according to the thermal source price, particularly produce the producer of calcium chloride with waste soda ash solution, drying cost accounts for the proportion of product total cost up to more than 70%.
The energy consumption of the Calcium Chloride Powder Anhydrous of ammonia alkali evaporated waste ammonia liquid manufacturing at present is: the ton product energy consumption of powdered anhydrous calcium chloride is 9,900,000 kilocalories.Under the situation of international energy anxiety, greatly wasted limited fuel source, energy consumption height not only, equipment volume is huge, and output is little, cost height and poor product quality.
Summary of the invention
Calcium Chloride Powder Anhydrous drying cost height, quality product are subjected to disadvantages such as secondary pollution in the traditional technology in equipment in order effectively to solve, two spray drying devices of this process using, by science connection and integrated, be combined into the continuous spray drying device that a cover concentrate drying calcining is integrated in one, with calcium chloride solution quick concentrate drying under atomize, thereby obtain the anhydrous chlorides of rase calcium product of better quality.Its technical scheme that adopts is: with pure calcium chloride water under the effect of high-pressure hydraulic pump, successively squeeze into " adverse current spraying concentration tower ", rapidly pure calcium chloride water concentration is brought up to about 55% in " adverse current spraying concentration tower ", inflow has in the plastics intercepting basin of insulation.Effect through high-pressure pump, the calcium chloride solution of 55% left and right sides concentration is successively sprayed in " flash spraying drying calcining tower ", in " flash spraying drying calcining tower ", rapidly with the calcium chloride water concentration and evaporation and slough water of constitution, under the effect of high-pressure suction fan, enter efficient powder collector, through efficient powder collector, extraordinary wind stopping device continuously, packing can obtain the anhydrous chlorides of rase calcium product.The high-temperature tail gas of the efficient powder collector of process enters in " adverse current flash spray tower " under the effect of high negative pressure, and in order to concentrate the calcium chloride original solution, the gas after concentrating enters atmosphere behind high-pressure suction fan, finish whole technological processs.
Beneficial effect
This technology makes material continuous concentration, drying, calcining under atomizing state, improved utilization efficiency of heat energy to greatest extent, shortened time of drying, solved present conventional production process the problem that concentrate drying forms in metal vessel to the material severe contamination, also solved simultaneously heavy corrosion problem to equipment, thereby increased product whiteness, improved quality product, reduced production cost.Consumption of this process fuel and power consumption all significantly are lower than conventional calcium chloride drying process, and the drying cost of Calcium Chloride Powder Anhydrous per ton reduces about 65% (different and different according to the thermal source price) than traditional technology.

Embodiment
With pure calcium chloride water under the effect of 4. high-pressure hydraulic pump, successively squeeze into 8. " adverse current spraying concentration tower ", rapidly pure calcium chloride water concentration is brought up to about 55% in " adverse current spraying concentration tower ", inflow has in the 10. plastics intercepting basin of insulation.Through the 9. effect of high-pressure hydraulic pump, the calcium chloride solution of 55% left and right sides concentration is successively sprayed among the " flash spraying drying calcining tower ", in " flash spraying drying calcining tower ", rapidly with the calcium chloride water concentration and evaporation and slough water of constitution, along with the hot gas flow from high temperature heat source enters the efficient powder collector of , through efficient powder collector, extraordinary wind stopping device continuously, packing can obtain the anhydrous chlorides of rase calcium product.8. the high-temperature tail gas of the efficient powder collector of process enters in " adverse current spraying concentration tower " under the effect of high negative pressure, and in order to concentrate the calcium chloride original solution, the gas after concentrating enters atmosphere behind high-pressure suction fan, finish whole technological processs.
