Description

Full closed circulation fluidized bed and its using and using method
Technical Field
The invention relates to a full-closed-circuit circulating fluidized bed and a using and applying method thereof, belonging to the technical field of circulating fluidized beds.
Background
The utility model discloses a medicine, edible material processing equipment ' of utility model 2014208581643, invention patent 2014108408080 ' circulating fluidized bed equipment ', 2014108417323 ' normal temperature air current drying equipment ' and so on are typical representatives of the third generation circulating fluidized bed, and figure 1 is an embodiment of the third generation circulating fluidized bed, and is composed of a fan 1, a positive pressure circulating pipe 2, a cyclone dust collector 3, a positive pressure circulating pipe 4, a dust collector branch 5, a tail gas processing device 6, a molecular sieve dryer 7, an air inlet air current heating device 8, a negative pressure circulating pipe 9 and an adjusting device; after materials are added by the atomizer 11 and the feeding valve 10 on the negative pressure circulating pipe, the materials are dispersed into particles to form a fluidized state under the action of the fan 1 and high-speed air flow generated by the fan, and the drying and crushing operation of the materials is realized in the process of high-speed circulating flow in the circulating pipeline, so that the method is suitable for processing most of the materials with micro powder in product form; the cyclone dust collector 3 serving as a first-stage material-gas separation device separates air flow from materials in a fluidized state, most of the separated materials and a small part of the separated air flow enter a negative pressure circulating pipe for circulation operation again, most of the air flow and the small part of the separated materials enter a dust collector branch 5 serving as a second-stage material-gas separation device, moisture discharged by the dust collector branch 5 is condensed and separated by a condenser 6, most of moisture enters a molecular sieve dryer 7 for deep dehydration, the deeply dehydrated air flow is heated by a heater 8 and then used as inlet air flow again, the embodiment realizes anaerobic closed circulation operation substantially, and most of the operation process can be controlled below 50 ℃ through an inlet air flow temperature adjusting device consisting of a temperature sensor 12, the heater 8 and a fan rotating speed adjusting device, so that rapid normal-temperature drying is realized. In practice, it has been found that there is a need for improvement in the apparatus, namely, in order to increase the flow velocity of the fluidized material, the total pressure of the fan is increased, which also increases the pressure in the positive pressure circulation pipe, due to the thermodynamic effect and after the drying process enters the deceleration drying period, the moisture in the material is reduced, so that the heat consumed by moisture gasification is greatly reduced, in order to control the temperature in the air conditioner to be below 50 ℃, the rotating speed of the fan needs to be reduced so as to reduce the heat converted from the kinetic energy of the fan, however, in order to maintain the fluidization state of the materials, particularly, high-speed airflow is needed to blow off the materials adhered to the pipe wall, the reduction of the rotating speed of a fan is limited to a certain extent, the lowest air flow can be reduced to room temperature, the third-generation circulating fluidized bed is not completely effective by a regulating method for controlling the temperature in the machine to be below 50 ℃ through an air flow temperature regulating device, and the normal-temperature operation becomes more and more the basic requirement for processing the materials used as medicines and foods; and secondly, the effective circulation and the fluidization state of the materials are sometimes realized by increasing the rotating speed of the fan and increasing the wind speed in the pipe, and the effective circulation and the fluidization state of the high-humidity and high-viscosity materials are ensured to be effective but not economical by simply increasing the rotating speed of the fan.
Nutrient (nutrient) is a substance which provides energy to organisms, repairs organism and tissue and has a physiological regulation function, agricultural production is an important subject for obtaining nutrient, and the increase of the nutrient output of unit farmland is an important subject, but the present method cannot realize the maximization of the nutrient output of the farmland. For a long time, most of grain production only aims at obtaining crop tissues with high nutrient content, the planting times of crops in the same region within one year are basically fixed due to the limitation of the growth period of the crops, and the grain production aiming at obtaining the crop tissues with high nutrient content cannot increase the yield by increasing the planting times. Research shows that the total amount of nutrients contained in plants is different during the whole growth period of the crops, and the maximum value of the total amount of nutrients contained in the plants is not in the harvesting time, so that obviously, if the total amount of the nutrients in the whole crop plants (but not in the crop tissues harvested in the traditional production) can be harvested and utilized when the content of the nutrients is proper, the growth period of the crops can be expected to be shortened, the planting times can be increased, and the nutrient output of cultivated land can be maximized.
Water from plant tissues has important value, at present, the method for obtaining the water from the plant tissues mainly adopts juicing, the purpose of the juicing is mainly to obtain soluble solid components in the plant tissues, and at present, no economically-cost method for preparing the water from the plant tissues without the solid components in a large scale mode exists. The water which is derived from the plant tissue and does not contain solid components is called plant dew, the plant dew is not only water, and the plant dew is rich in volatile components in plants.
The volatile components contained in the plants are the most important active components, in particular plant essential oil and medicinal plants such as volatile oil in pseudo-ginseng, glucosinolate in maca and the like. Most available plant tissues can be stored after being dried, most of important volatile substances are lost due to volatilization during drying processing, for example, after the fresh maca fruits are dried, glucosinolates are reduced to below 50% of the dry basis of the fresh maca fruits, after the fresh panax notoginseng fruits are dried, volatile oil in the fresh panax notoginseng fruits is lost to different degrees, and the existing method for preparing the volatile components in the plants is not economical.
According to literature data, the grain diameter range of the food material and Chinese medicinal material ultrafine powder is 1-75um, and the ultrafine powder has higher processing cost, so that the ultrafine powder is only used in the aspects of high-grade nourishing nutriments, health-care foods, medicinal materials and the like at present. The common food materials are more beneficial to digestion and absorption after being subjected to superfine grinding, the utilization efficiency of the feed materials is improved after being subjected to superfine grinding, the plant absorbability is improved by the fertilizer after being subjected to superfine grinding, and although the common food materials, the fertilizer and the feed materials are prepared into superfine powder and then are used, the beneficial effect is obvious, the application mode is not completely feasible economically due to too high processing cost of the superfine powder.
The conventional distillation method basically adopts heating to gasify the fraction and then liquefies the gaseous fraction to extract the gasifiable components in the material, and the conventional distillation method is not economical due to the fact that the gasification speed of the gasifiable components is not high and the liquefaction of the gaseous fraction consumes extra energy.
In summary, the conventional process involving drying, ultrafine grinding, evaporation distillation, concentration, gasification liquefaction, mixing, etc. has problems of high energy consumption, high processing cost and difficult quality assurance due to factors such as insufficient water and heat exchange speed between the material and the operation medium, long process flow, high operation temperature, etc., so that it is not completely feasible in economic aspects to solve common problems of rapid normal temperature drying in the production of intermediate raw material products, ultrafine grinding of large-scale materials, large-scale preparation of volatile components in the materials, etc.

Example 17: a method for utilizing a refrigeration facility, wherein the refrigeration facility is used as a cold source of a full-closed circulating fluidized bed and/or the refrigeration facility is used as a heat source of the full-closed circulating fluidized bed.
The refrigeration equipment is a device for realizing heat transfer from one space to another space by utilizing a refrigerant as an energy carrier through the phase change from liquid to gas for heat absorption and the phase change from gas to liquid for heat release, the energy consumed for realizing the transfer is far less than the transferred heat, the refrigeration equipment is a device for realizing high-efficiency heat enrichment and cold enrichment, the parameter for measuring the energy transfer efficiency of the refrigeration equipment is an energy efficiency ratio, the energy efficiency ratio is defined as the ratio of the effective energy of the enrichment to the energy consumed for realizing the energy enrichment, and the currently widely used refrigeration equipment realizes the energy efficiency ratio of more than 3.0. Although the refrigeration equipment can simultaneously realize the accumulation of cold and heat, the refrigeration equipment only needs to heat or refrigerate at an application place, so the refrigeration equipment only generally utilizes the accumulated cold or the accumulated heat at present, and rarely can simultaneously utilize the accumulated cold and the accumulated heat; on the other hand, because the refrigeration equipment can only output heat carriers below 100 ℃ generally, the heat carriers are only used in the occasions with the temperature of 20-70 ℃ as heat sources generally, the fully-closed circulating fluidized bed needs cold energy and heat simultaneously, and the temperature of the inlet airflow is below 100 ℃ generally, so that the fully-closed circulating fluidized bed becomes an excellent application occasion of the refrigeration equipment; the method enables the full-closed-circuit circulating fluidized bed to have wider energy-saving prospect.
