This means industrial 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 inner system. One economical, environment amenable Waste Water Treatment should be a factory or part indispensable in the entirety planning of workshop. Waste water vaporizer mainly is applicable to have xln to precipitate out evaporation and the crystallization of solution, is widely used in chemical industry industry, the smelting of Metal mining, the big spent pickle liquor of section steel works, the wet desulphurization liquid waste disposal etc. of power plant. But existing triple-effect evaporator is arranged as evaporation, it is necessary to auxiliary heating energy source, energy consumption is big, cost height.
Practical novel content
The purpose of this utility model 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 characterised in that: comprise for pressurized air obtain the vacuum compression pump of high-temperature high-pressure steam, the heat-exchanger rig utilizing described High Temperature High Pressure to steam steam and heated by waste water, for separating of the separator of gas and liquid; Described heat-exchanger rig comprises preheating heat exchanger and evaporating heat exchanger; The high-temperature high-pressure steam delivery port of described vacuum compression pump connects the entrance of described evaporating heat exchanger, described preheating heat exchanger and described vacuum compression pump successively; The entrance of described waste water vaporizer successively connects described preheating heat exchanger, described evaporating heat exchanger, described separator successively; The waste water that the separation of described separator obtains 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, it is not necessary 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 vapour 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, heat exchange efficiency height, and Impurity deposition probability is little, and fouling tendency is low. Owing to fluid flows in helical channel, can reaching turbulent flow, and can select higher flow velocity under lower Reynolds value, overall heat transfer coefficient is bigger. Owing to 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 blocking region is played again souring, therefore spiral-plate heat exchanger is not easily blocked.
As preferably, described evaporating heat exchanger is tubular heat exchanger.
As preferably, described tubular heat exchanger comprises at least two heat transfer tubes being connected in parallel. Many heat transfer tube is connected in parallel, and increases heat interchanging area, it is to increase heat exchange efficiency.
As preferably, arranging Ceramic Balls in described heat transfer tube. Described Ceramic Balls surface has hole, it is possible to 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, it is to increase heat exchange effect when waste water flows through from the described heat transfer tube being built-in with described vitrified pipe.
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 friction with described heat transfer tube inwall, cleans described Tube Sheet of Heat Exchanger by described Ceramic Balls inner, prevents heat transfer tube fouling.
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 useful effect: the rate of heating of described vacuum compression pump is fast, it is not necessary 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 vapour 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 the system architecture figure of a kind of waste water vaporizer.
Embodiment
Below in conjunction with accompanying drawing, enforcement mode of the present utility model is described in detail. A kind of waste water vaporizer, comprises and obtains the vacuum compression pump of high-temperature high-pressure steam, the heat-exchanger rig utilizing high temperature and high pressure steam to be heated by waste water, separator for separating of gas and liquid for pressurized air.
Heat-exchanger rig comprises preheating heat exchanger and evaporating heat exchanger, and wherein preheating heat exchanger is spiral-plate exchanger, and evaporating heat exchanger is tubular heat exchanger. Spiral-plate exchanger forms two spirality channels by two pieces of sheet metals in device. When carrying out heat exchange, cold and hot fluid enters two passes counter-current flow respectively. Tubular heat exchanger comprises at least two heat transfer tubes being connected in parallel, and increases the heat interchanging area with waste water. Arranging Ceramic Balls in heat transfer tube, the diameter of Ceramic Balls preferably equals the internal diameter of heat transfer tube. When waste water flows through heat transfer tube, Ceramic Balls and heat transfer tube inwall produce friction and prevent heat exchange in-tube fouling.
