Abstract
The invention discloses an evaporation and concentration device for a corrosive liquid material, which comprises a falling film evaporator, a compressor, a secondary vapor condenser and a water pump. The evaporation and concentration device is a set of chlorate waste liquid falling film evaporator and a set of medium cooling circulation system, wherein the chlorate waste liquid falling film evaporator is used for evaporating and concentrating chlorate waste liquidchlorates and consists of a medium cooling circulation system compressor, thea falling film evaporator and thea secondary vapor condenser. Cooler vapor with relatively high temperature behind the outlet of the compressor is used for heating the chlorate waste liquid to evaporate and concentrate diluted solution of a chlorate; a cooling medium evaporates and absorbs the heat during condensation of secondary vapor in the secondary vapor condenser; and the water pump is arranged at the outlet of the secondary vapor condenser and can quickly drain condensed water in a negative pressure state, and then the secondary vapor smoothly enters the secondary vapor condenser and is condensed.
Description
Technical field:
The present invention relates to a kind of industry and concentrate production technology, particularly a kind of evaporating and concentrating process technical field that is applicable to corrosive liquids materials such as chlorate.
Background technology:
Chlorate is the corrosive liquids material like clorox, potassium hyperchlorate etc., is one of industrial chemicals of using always, and clorox is widely used in the sterilization that comprises running water, Zhong Shui, industrial circulating water, swimming-pool water, hospital sewage or the like various water bodys.Clorox can also destroy cyanide ion and phenyl ring etc.; Advanced oxidation as Treatment of Cyanide-containing Wastewater and some industrial serious pollution waste water; Can also be used for bleachings such as paper pulp, what the clorox liquid of high concentration can also be used for adhering on peel-off device and the pipeline is stained with mud.
Clorox belongs to strong base-weak acid salt, and it is as clear as crystal, is a kind of liquid that can be dissolved in water fully.But because sodium hypochlorite solution is heated and be prone to decomposes, have strong oxidizing property, be difficult for stored for a long timely, clorox is many with electrolysis low concentration saline solution in situ preparation.
In fact prepare clorox through electrolysis low concentration saline solution and will consume a large amount of electric energy; And in the waste liquid after the sterilization; Often also have a spot of clorox,, for enterprise, will reduce cost if can reclaim this a part of clorox; And can reduce pressure, so the inevitable choice of the recycling manufacturing enterprise of clorox to environment.
Reclaim the waste liquid that these contain clorox, the angle from making full use of the natural resources no matter is still from point of view of environment protection; All be noticeable problem, and liquor natrii hypochloritis's characteristics are to have strong oxidizing property, determined it concentrate with other solution concentration process be different; In addition; The liquor natrii hypochloritis is unstable, meets heat and is prone to decompose, and therefore can only under low-temp low-pressure, evaporate.
Concentrate in the treatment process commonly used at waste liquid; Evaporation technique is a kind of technology commonly used; Traditional evaporation process just is to use living Steam Heating weak solution, produces condensed water after the steam heat release condensation and discharges, and the higher indirect steam of the temperature that produces after the water evaporates in the weak solution is directly got rid of; A kind of dilute sulfuric acid evaporation and concentration scheme like the design of the grand technological development in Guangzhou Co., Ltd; The multiple-effect evaporation form that it adopts, first imitates the living steam that has used 0.6MPa, and in the end an effect has adopted the higher steam of water quench temperature.Will cause the consequence of two aspects like this: 1) the indirect steam temperature is higher, and directly discharging can increase operating cost, wastes energy; 2) will carry a spot of drop secretly in the indirect steam, will cause the loss of solute like this, also will pollute the environment.
Summary of the invention:
The object of the invention provides the evaporation concentration device of a kind of energy-conservation, low consumption, free of contamination corrosive liquids material.
Apparatus of the present invention comprise falling film evaporator, compressor, secondary steam condenser, water pump; The feed tube of corrosive liquids material is connected an entrance point of falling film evaporator; With connect the high-temperature vapor port of export on the falling film evaporator that this entrance point is connected, falling film evaporator also is provided with the concentrated liquid material port of export; Said falling film evaporator also is provided with the heat transferring medium entrance point and the port of export; Said secondary steam condenser is provided with the heat transferring medium entrance point and the port of export; The heat transferring medium port of export of said falling film evaporator is connected with the heat transferring medium entrance point of secondary steam condenser through choke valve, and the heat transferring medium port of export of said secondary steam condenser is connected with the heat transferring medium entrance point of falling film evaporator through compressor; Said secondary steam condenser also is provided with steam entrance point and condensation-water drain end; The high-temperature vapor port of export of said falling film evaporator is connected with the steam entrance point of secondary steam condenser, and the condensation-water drain end of said secondary steam condenser connects drainpipe through water pump.
The present invention is a cover chlorate waste liquid falling film evaporator and a cover medium cooling cycle system, and chlorate waste liquid falling film evaporator supplies chlorate waste liquid evaporation and concentration to use, and is made up of medium cooling cycle system compressor, falling film evaporator, indirect steam condenser.The higher refrigerant vapour of temperature behind the compressor outlet is used for the chlorate waste liquid is heated, and makes chlorate weak solution evaporation and concentration; Refrigerant absorbs the heat of indirect steam condensation in the evaporation of indirect steam condenser the inside; Outlet at the indirect steam condenser is provided with a water pump, can make to be under the negative pressure state condensed water and to discharge rapidly, and indirect steam gets into condenser condenses smoothly.
The present invention places the refrigerant loop with compressor, can protect compressor, prolongs the life-span of compressor; Because steam specific volume under worst cold case is very big, be the hundreds of times of refrigerant specific volume under this temperature approximately again.If adopt the direct pressurized water steam of compressor, the volume of compressor will be very big, is arranged in compressor in the refrigerant loop, just can reduce the compressor volume greatly, practices thrift to concentrate cost.
In addition, heat exchanger of the present invention all adopts the heat exchanger of falling liquid film form, and is circulation form, so just can reduce heat exchanger tube length, the stability and the security of the operation of raising system.
