[0029] The following is combined with Figure 1 This application is described in further detail.
[0030] The present application embodiment discloses a multi-component concentration system for extracting traditional Chinese medicine and plants. Figure 1A multi-component concentration system for extracting traditional Chinese medicine and plants includes a preheater 1, a concentrator 2, a heater 3, a compressor 4, a condenser 5, a cooler 6 and a liquid receiving tank 7. A feed pipe is fixed on the concentrator 2, one end of the feed pipe is connected and communicated with an external raw material tank, and the other end of the feed pipe is communicated with the inside of the concentrator 2. A feed pump is fixed on the feed pipe, and the raw material is transported to the concentrator 2 through the feed pipe by the feed pump. A first circulation pipeline is fixed on the concentrator 2, and a circulation pump 8 is fixed on the first circulation pipeline. The preheater 1 and the concentrator 2 are connected and communicated through the first circulation pipeline. The raw material in the concentrator 2 is circulated and preheated in the preheater 1 through the first circulation pipeline under the action of the circulation pump 8. A steam condensation water channel is provided in the preheater 1. When the preheater 1 is in operation, the raw steam enters the steam condensation water channel, and the raw steam in the steam condensation water channel exchanges heat with the raw material to preheat the raw material. When preheated to a certain temperature, the raw steam stops entering the preheater 1, and the raw material is subsequently heated by the heater 3.
[0031] A feed pipe is also fixed on the preheater 1, and a feed pump is fixed on the feed pipe. The preheater 1 is connected and communicated with the heater 3 through the feed pipe, and the preheated raw materials are transported to the heater 3 through the feed pipe by the feed pump for heating. A second circulation pipeline is fixed on the heater 3, and the second circulation pipeline is connected and communicated with the first circulation pipeline. The second circulation pipeline is connected and communicated with the preheater 1 through the first circulation pipeline, thereby realizing the connection and communication between the heater 3 and the preheater 1. The raw materials preheated by the preheater 1 are circulated and heated in the heater 3 and the preheater 1 through the circulation pump 8 until the temperature reaches the standard. At this time, the raw steam has stopped entering the preheater 1. A feed pipe is fixed on the heater 3, and the heater 3 is connected and communicated with the concentrator 2 through the feed pipe. The raw materials that meet the heating standards enter the concentrator 2 through the feed pipe for evaporation and separation.
[0032] The temperature of the concentrator 2 is controlled at 40°C to 50°C. Through low-temperature evaporation, the effective ingredients in the raw materials can be greatly retained, and the product quality can be improved. A vacuum pipeline is fixed on the top of the concentrator 2. The condenser 5 is connected and communicated with the concentrator 2 through the vacuum pipeline. The water vapor generated during the evaporation of the concentrator 2 enters the condenser 5 through the vacuum pipeline to condense and form a condensed liquid. A condensed liquid outlet pipeline is fixed on the condenser 5. The condenser 5 is connected and communicated with the cooler 6 through the condensed liquid outlet pipeline. The condensed liquid temperature is high. The condensed liquid enters the cooler 6 through the condensed liquid outlet pipeline for cooling. A cooling liquid outlet pipeline is fixed on the cooler 6. The cooler 6 is connected and communicated with the liquid receiving tank 7 through the cooling liquid outlet pipeline. The cooled cooling liquid enters the liquid receiving tank 7 for storage. A discharge pipeline is provided at the bottom of the concentrator 2. A discharge pump 9 is fixed on the discharge pipeline. The concentrated liquid formed after the raw material is evaporated stays in the concentrator 2. When the concentration of the concentrated liquid formed after the raw material in the concentrator 2 is evaporated reaches the design value, it is discharged from the discharge pipeline through the discharge pump 9 to the outside of the concentrator 2.
[0033] Furthermore, the compressor 4 is connected between the condenser 5 and the heater 3. The condenser 5 is provided with a refrigerant. The compressor 4 is used to drive the refrigerant in the condenser 5 to circulate. When the refrigerant circulates, it absorbs heat from the water vapor entering the condenser 5, and then flows into the heater 3 to dissipate heat, thereby heating the raw material. An air outlet pipe is fixed on the heater 3, and a condensed water inlet and a condensed water outlet are provided on the condenser 5. The heater 3 is connected and communicated with the condensed water inlet of the condenser 5 through the air outlet pipe. After the refrigerant flowing into the heater 3 dissipates heat, it is transported to the condenser 5 through the air outlet pipe to form a part of condensed water to help condensation, so that the energy generated during the operation of the condenser 5 and the heater 3 can be fully utilized. Thereby, energy reuse, energy saving and emission reduction are achieved, the energy consumption of the concentration system is reduced, and the operating cost is reduced. The outlet of the condenser 5 is connected to the condensed water pump through a pipeline, and the used condensed water is finally discharged by the condensed water pump.
[0034] In addition, a water inlet pipe is fixed on the top of the concentrator 2 and the liquid receiving tank 7, and a sewage pipe is fixed on the bottom of the concentrator 2 and the liquid receiving pipe. When the concentrator 2 and the liquid receiving tank 7 need to be cleaned, water is introduced into the water inlet pipe to flush the concentrator 2 and the liquid receiving tank 7, and the sewage after flushing is discharged from the sewage pipe, which is convenient for the operator to clean the concentrator 2 and the liquid receiving tank 7 regularly.
[0035] Furthermore, a temperature sensor and a pressure transmitter are installed on the vacuum pipe to monitor the temperature and pressure of the water vapor respectively. The temperature sensor and the pressure transmitter enable the temperature and pressure of the water vapor to be monitored in real time, so that the operator can understand the operation status in real time and take timely response measures.
[0036] Furthermore, the liquid receiving tank 7 is fixedly connected with a vacuum pipe and a liquid discharge pipe, a vacuum pump 10 is fixed on the vacuum pipe, and a liquid discharge pump 11 is fixed on the liquid discharge pipe. The vacuum pump 10 can perform vacuum treatment on the liquid receiving tank 7. Since the liquid receiving tank 7, the cooler 6, the condenser 5 and the concentrator 2 are all connected and communicated through pipelines, the vacuum pump 10 can extract the air in the liquid receiving tank 7, the cooler 6, the condenser 5 and the connected pipelines when vacuuming, and the non-condensable gas in the condenser 5 that is not condensed during condensation is also extracted, reducing the gas content in the liquid receiving tank 7, the cooler 6, the condenser 5 and the connected pipelines, thereby reducing the boiling point of the raw materials in the concentrator 2, making the raw materials in the concentrator 2 boil faster, and improving the concentration efficiency. It also reduces the occurrence of the situation where the gas in the liquid receiving tank 7 affects the stability and uniformity of the liquid, and at the same time reduces the chemical effect of the gas on the liquid. When the liquid in the liquid receiving tank 7 reaches a certain amount, the liquid can be extracted by the liquid discharge pump 11, which is convenient for the subsequent storage of the liquid in the liquid receiving tank 7.
[0037] During the operation of the multi-component concentration system for traditional Chinese medicine and plant extracts, the raw materials are preliminarily preheated by the preheater 1 before entering the heater 3, and the raw steam enters the preheater 1 to preheat the raw materials. When preheated to a certain temperature, the raw steam stops entering the preheater 1, and the raw materials are subsequently heated by the heater 3, which greatly reduces the use of raw steam. The compressor 4 drives the refrigerant to circulate. When the refrigerant circulates, it absorbs heat from the water vapor entering the condenser 5, and then flows to the heater 3 to dissipate heat and heat the raw materials. The energy generated during the operation of the condenser 5 and the heater 3 can be fully utilized. The amount of condensed water consumed by the condenser is greatly reduced, and the consumption of condensed water can be ignored, so only the power cost of the required pump is considered. The energy saving comparison is calculated based on 300 yuan / ton of steam, 0.7 yuan / kw of electricity, and 0.2 yuan / ton of cooling water loss. Comparison of energy consumption based on evaporation of 1t / h of raw liquid:
[0038] project Ordinary concentrator Energy-saving concentration system Steam consumption / hour 1.2t - Power consumption / hour 8kw 129kw Water / hour 60t - Energy consumption per hour 377.6 yuan 90.3 yuan Annual energy consumption 2.49 million yuan 600,000 yuan
[0039] It can be seen that the annual operation time is calculated as 20 hours / day*330 days / year=6600 hours / year. The annual operation cost of this energy-saving concentration system is 1.89 million yuan less than that of ordinary concentrators, and the operation cost is greatly reduced. It also reduces energy consumption and helps reduce environmental pollution.
[0040] The implementation principle of a multi-component concentration system for extracting traditional Chinese medicine and plants in the present application is as follows:
[0041] The raw material is transported to the concentrator 2 through the feed pipe by the feed pump, and the raw steam enters the preheater 1 as a heat source. The raw material in the concentrator 2 enters the preheater 1 through the first circulation pipeline through the action of the circulation pump 8 to exchange heat with the raw steam, and circulates and preheats in the preheater 1. The preheated raw material is circulated and heated in the heater 3 and the preheater 1 by the action of the circulation pump 8 until the temperature reaches the standard, and then enters the concentrator 2 for evaporation and separation. The water vapor generated by the raw material in the concentrator 2 during the evaporation process enters the condenser 5, and the water vapor is condensed into high-temperature condensed liquid by the condenser 5 and then enters the cooler 6 for cooling. The cooled liquid enters the liquid receiving tank 7 for storage. The concentrated liquid formed after the raw material is evaporated stays in the concentrator 2. When the concentration of the concentrated liquid in the concentrator 2 reaches the design value, it is discharged from the bottom of the concentrator 2 through the discharge pump 9.
[0042] Through the action of the compressor 4, the refrigerant circulates and absorbs heat from the water vapor entering the condenser 5, and then flows to the heater 3 to dissipate heat and heat the raw materials. The energy generated during the operation of the condenser 5 and the heater 3 can be fully utilized. Thus, energy reuse is achieved, energy saving and emission reduction are achieved, the energy consumption of the concentration system is reduced, and the operating cost is reduced. The operator regularly cleans the concentrator 2 and the liquid receiving tank 7, and the water inlet pipe is used to flush the concentrator 2 and the liquid receiving tank 7, and the flushed sewage is discharged from the sewage pipe.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
