Description
Technical field
The present invention relates to a kind of vacuum concentrator, belong to evaporation equipment technical field.
Background technology
In the technical fields such as chemical industry, pharmacy and food, often need to concentrate feed liquid, inspissator, just for evaporating the solvent in feed liquid, extracts the equipment of high-purity feed liquid.Inspissator is divided into normal pressure inspissator and high pressure inspissator according to its pressure difference, for normal pressure inspissator, in order to improve its thickening efficiency, needing higher thickening temperature, correspondingly also increasing energy consumption; And when containing heat-sensitive substance in material to be concentrated, heat-sensitive substance is at high temperature sex change easily, have impact on the stability of enriched product quality.
In order to overcome the above-mentioned shortcoming of normal pressure inspissator, researcher proposes a kind of vacuum concentrator, and it can concentrate at a lower temperature, not only reduces energy consumption, and heat-sensitive substance also maintains stability in concentration process.As Chinese patent literature CN2332406Y discloses a kind of traditional Chinese medicine extraction concentrator, comprise extractor, heater and evaporimeter, the top of heater is connected with evaporimeter, the position of extractor is higher than heater and evaporimeter, heater is connected by the drug liquid tube with by-pass valve control with the bottom of extractor, the liquid in extractor can under gravity through the control flow check of by-pass valve control to heater; The top of extractor is also provided with reflux condenser, and the outlet of reflux condenser is communicated with vacuum system; Be provided with the steam pipe with extracting valve between extractor and the top of evaporimeter, steam pipe is by being connected with another entrance reclaiming condenser with the recovery tube reclaiming valve, and the outlet of this recovery condenser is also connected with vacuum system; The bottom of reclaiming condenser is recycling cavity, and the below of recycling cavity is recycling can, and the bottom of recycling cavity is connected with recycling can with fluid-through tube by breather pipe, and breather pipe is provided with breather valve, fluid-through tube is provided with logical liquid valve.When needs carry out concentrated separately, closing control valve and extraction valve, open recovery valve, while heater leads to steam to evaporimeter, vacuum system vacuumizes evaporimeter by reclaiming condenser, in removal process, breather valve and logical liquid valve are closed, constantly condensate liquid is accumulated in recycling cavity, when running up to a certain degree, first stop vacuumizing and logical steam, open breather valve and logical liquid valve more successively, make condensate stream in recycling can, again close breather valve and logical liquid valve after emptying and carry out next round and vacuumize and concentrate.In above-mentioned technology, all need first to stop vacuumize and logical steam before condensate liquid being recycled to recycling can at every turn, after reclaiming condensate liquid, also need carry out emptying to device and again vacuumize and could again concentrate, not only complex operation, energy consumption increase, and thickening efficiency is very low.
In order to solve the technical problem that above-mentioned vacuum concentrator in use exists, Chinese patent literature CN201949667U discloses a kind of dual-effect concentrator, comprises the effect heater and evaporimeter, two effect heater and evaporimeter, water knockout drum and condensers that sequentially connect; Condenser connects total vacuum tube, and total vacuum tube connects vacuum system; The below of condenser is provided with submerged soil, and the inside of submerged soil is provided with a dividing plate and submerged soil inner sealing is divided into upper and lower, and wherein the top of submerged soil is connected with the bottom of condenser; Submerged soil cell wall is provided with a bypass vacuum tube bottom of submerged soil is connected with total vacuum tube, and be provided with a branch vacuum pipe top of submerged soil is connected with bypass vacuum tube, branch vacuum pipe is provided with vacuum communicating valve, on bypass vacuum tube, between branch vacuum pipe and bypass vacuum tube, is provided with vacuum by-pass valve.Time concentrated, close vacuum by-pass valve, open vacuum communicating valve, vacuum system by total vacuum tube for inspissator provides vacuum environment, when the concentrate of submerged soil bottom is stacked into a certain degree, close vacuum communicating valve, by the bottom tapping of submerged soil, emptying, first open vacuum by-pass valve afterwards, with system vacuum, supplementary vacuum is carried out to submerged soil bottom, when equaling the vacuum in dual-effect concentrator Deng the vacuum in submerged soil, close vacuum by-pass valve, and open vacuum communicating valve simultaneously, recover the collective low condensate liquid to submerged soil.
In above-mentioned technology, the setting position of total vacuum tube is near the condensate liquid collected, and therefore vacuum system is easily by the condensate liquid collected by total vacuum tube sucking-off, not only causes the loss of solvent, also easily damages vacuum equipment simultaneously.
In addition, although when each discharge condensate liquid, without the need to carrying out emptying to whole inspissator and again vacuumizing, only need emptying be carried out to the bottom of submerged soil and heavily vacuumize, decrease energy consumption to a great extent, improve thickening efficiency; But, above-mentioned inspissator all needs to regulate vacuum communicating valve and vacuum by-pass valve before and after each discharge condensate liquid, complex operation, and to the emptying of submerged soil bottom with vacuumize and still can waste portion of energy, cause the thickening efficiency of vacuum concentrator to reduce.
Summary of the invention
