Description
Technical field
The present invention relates to technical field of waste water processing, particularly relate to a kind of waste water vaporizer.
Background technology
Water purposes is industrially a lot, and typical industrial application has: water of productive use, rinsing water, washing and cooling water.This means industrially to have a large amount of waste water containing various high density pollution thing and produce.In most cases, these waste water needs after process, just can be discharged in public drainage or river, lake and ocean in built-in system.Economic, environment amenable Waste Water Treatment should be part indispensable in a factory or workshop integrated planning.Waste water vaporizer is mainly applicable to evaporation and the crystallization that xln separates out solution, is widely used in chemical industry, the smelting of Metal mining, the spent pickle liquor of large-scale steel mill, the wet desulphurization liquid waste disposal etc. of power plant.But existing triple-effect evaporator is arranged as evaporation, need auxiliary heating energy source, energy consumption is large, cost is high.
Summary of the invention
The object of the invention is to solve the high technical problem of existing waste water vaporizer running cost, a kind of energy-efficient waste water vaporizer is provided, it is characterized in that: comprise the vacuum compression pump obtaining high-temperature high-pressure steam for pressurized air, the heat-exchanger rig, the separator for separating of gas and liquid that utilize described High Temperature High Pressure to steam steam to heat waste water; Described heat-exchanger rig comprises preheating heat exchanger and evaporating heat exchanger; The high-temperature high-pressure steam that described vacuum compression pump exports circulates successively between described evaporating heat exchanger, described preheating heat exchanger and described vacuum compression pump; Described waste water is successively successively through described preheating heat exchanger, described evaporating heat exchanger, described separator; Described separator is separated the waste water obtained and discharges described waste water vaporizer; Described waste water vaporizer is discharged in the waste water crystallization that described evaporating heat exchanger obtains.The rate of heating of described vacuum compression pump is fast, without the need to the external heat source that electricity, steam or hot water etc. are additional.Described preheating heat exchanger utilizes the pre-thermal wastewater of water vapor waste heat of described evaporating heat exchanger, can reduce energy consumption like this.
As preferably, described preheating heat exchanger is spiral-plate exchanger.Spiral-plate exchanger turbulence effects is good, and heat exchange efficiency is high, and Impurity deposition probability is little, and fouling tendency is low.Because fluid flows in helical channel, can reach turbulent flow under lower NR, and can select higher flow velocity, overall heat transfer coefficient is larger.Because the flow velocity of fluid is higher, in fluid, suspended substance not easily deposits, and any settling is by reducing the transverse section of single channel, thus makes speed increase, and play souring again, therefore spiral-plate heat exchanger is not easily blocked to blocking region.
As preferably, described evaporating heat exchanger is tubular heat exchanger.
As preferably, described tubular heat exchanger comprises at least two heat transfer tubes be connected in parallel.Many heat transfer tube is connected in parallel, and increases heat interchanging area, improves heat exchange efficiency.
As preferably, in described heat transfer tube, Ceramic Balls is set.Described Ceramic Balls surface has hole, can adsorbed oil smoke particle, reaches the effect of filtration.Meanwhile, described Ceramic Balls is heated in described heat transfer tube, considerably increases heat interchanging area when waste water flows through from the described heat transfer tube being built-in with described vitrified pipe, improves heat transfer effect.
As preferably, the diameter of described Ceramic Balls equals described heat transfer tube internal diameter.In still-process, described Ceramic Balls is rolled along with the flowing of described heat exchange liquid in pipe, produces rub with described heat transfer tube inwall, cleans described Tube Sheet of Heat Exchanger inner, prevent heat transfer tube fouling by described Ceramic Balls.
As preferably, described heat transfer tube is dismountable to be arranged in described tubular heat exchanger.Care and maintenance is more convenient.
The utility model has following beneficial effect: the rate of heating of described vacuum compression pump is fast, without the need to the external heat source that electricity, steam or hot water etc. are additional.Described preheating heat exchanger utilizes the pre-thermal wastewater of water vapor waste heat of described evaporating heat exchanger, can reduce energy consumption like this.Ceramic Balls is set in described heat transfer tube in still-process, cleans described Tube Sheet of Heat Exchanger inside by described Ceramic Balls, cut operating costs by the rate of evaporation of lower energy consumption and Geng Gao.
Accompanying drawing explanation
Fig. 1 is a kind of system construction drawing of waste water vaporizer.
