Abstract
The invention provides a double-effect outer circulation concentration evaporator, which is characterized in that a foam catcher is arranged in the evaporator, foam in substances evaporated in the evaporator can be removed by the foam catcher, so that problem of difficult foam removal during the operation of the evaporator can be solved, entrainment in secondary steam can be separated, operation condition can be improved, technical index is optimized, treating capacity is increased, valuable material is recovered, environment is protected, and atmosphere pollution is reduced.
Description
Technical field
The present invention relates to for industry liquid material evaporation and concentration such as Chinese and Western medicine, light industry, food and receive cream field, relating in particular a kind of economic benefits and social benefits outer circulation concentration evaporator of foam removal automatically.
Background technology
Mechanical steam recompression (MVR) evaporimeter utilizes the indirect steam producing in evaporimeter, and through compressor compression, pressure, temperature raise, heat content increases, then deliver to the heating clamber of evaporimeter and be used as heating steam use, make feed liquid maintain fluidized state, heating steam itself is condensed into water.Like this, originally will just be fully utilized by discarded steam, and reclaimed latent heat, and improved again the thermal efficiency, the economy of raw steam is equivalent to 30 effects of multiple-effect evaporation, has reduced the demand to external heat and cooling resource, reduces energy consumption, reduces and pollutes.Because evaporimeter is concentrated under vacuum state, a lot of viscosity is high produces foam while having material evaporation easy to foaming, and active ingredient in material can be wrapped in foam, finally slatterns.The problem that while therefore, solving evaporator operation, foam cannot be removed just seems particularly important.
Summary of the invention
The economic benefits and social benefits outer circulation concentration evaporator that the object of this invention is to provide a kind of foam removal automatically, by foam catcher is installed in evaporimeter, by foam catcher, the foam in the material evaporating in evaporimeter is carried out to foam removal, the problem that while having solved evaporator operation, foam cannot be removed.
The invention provides a kind of economic benefits and social benefits outer circulation concentration evaporator, comprise an effect heater, 1st effective evaporator, two effect heaters, 2nd effect evaporator, condenser and collecting tank, described 1st effective evaporator is arranged on the right of an effect heater, two effect heaters are arranged on the right of 1st effective evaporator, described 2nd effect evaporator is arranged on the right of two effect heaters, described condenser is arranged on the right of 2nd effect evaporator, described collecting tank is arranged on the right-hand member of condenser, a described effect heater, 1st effective evaporator, two effect heaters, 2nd effect evaporator, condenser is adjacent with collecting tank to be connected by pipeline between the two, in described 1st effective evaporator and 2nd effect evaporator, be provided with foam catcher, described foam catcher by silk screen and silk screen grid form silk screen piece and fixedly the supporting arrangement of silk screen piece form, described foam catcher is arranged on the entrance place on 2nd effect evaporator right side.
Further improve and be: described silk screen piece is generally the gas-liquid filter net of various materials, and gas-liquid filter net is that multiply non-metallic fibers twisting forms.
Further improve and be: be described for being provided with flow rate measurement valve on the pipeline connecting, for detection of the mass flow circulating in pipeline.
Further improve and be: the steam pressure in described 1st effective evaporator and 2nd effect evaporator is less than 0.25Mpa.
Beneficial effect of the present invention: foam catcher is installed in vaporization chamber indirect steam exit, is prevented the escape of active ingredient.Wire mesh demister by by silk screen, silk screen grid, formed silk screen piece and fixedly the supporting arrangement of silk screen piece form, the gas-liquid filter net that in general silk screen is various materials, gas-liquid filter net is comprised of wire or nonmetal wire.The nonmetal wire of gas-liquid filter net is formed by multiply non-metallic fibers twisting.This wire mesh demister not only can filtering be suspended in the larger liquid foam in air-flow, and energy filtering is less and minute liquid foam.When the gas with mist rises by silk screen with certain speed, due to the effect of inertia that mist rises, mist silk screen filament collides and is attached in filament surfaces.The diffusion of mist in filament surfaces is, the gravitational settling of mist makes the larger drop of mist formation flow to the interface point of two rhizoids along filament.The capillarity of the wettability of filament, the surface tension of liquid and filament, make drop increasing, until the drop of assembling is while arrive greatly making a concerted effort of climbing power that the gravity himself producing surpasses gas and surface tension of liquid, drop is separation whereabouts from filament just.Gas, by after wire mesh demister, does not basically contain mist.Mist in separated secondary steam, to improve operating condition, Optimization Technology index, increases treating capacity and reclaims valuable material, and protection of the environment reduces atmosphere pollution etc.
