Description

Technical Field

[0001] The utility model relates to the technical field of Chinese liquor brewing, and particularly relates to a steam recovery control system for the distillation and condensation link of Chinese liquor. Background Technique

[0002] As one of the "six major distilled spirits in the world", Chinese liquor has its profound cultural heritage and unique brewing process. The core process of Chinese liquor production - the distillation link determines the extraction efficiency of alcohol concentration and flavor substances, and is related to the final quality and liquor yield of Chinese liquor. The distillation and liquor flowing process is often divided into the stages of head liquor, high-quality liquor, and tail liquor (the strong-flavor process includes steaming grains with high heat). When distilling head liquor and high-quality liquor, due to the high alcohol concentration and the low boiling point of ethanol, it is often necessary to precisely control the flow rate of distillation steam; during the distillation of tail liquor or the steaming of grains, the proportion of water increases, the boiling point of flavor substances increases, and at the same time, to ensure the gelatinization of grains, it is necessary to increase the steam consumption. The above liquor flowing and grain steaming processes consume a large amount of steam and generate a large amount of waste heat and waste steam. The traditional treatment process mostly directly uses a condensing device to separately condense high-temperature liquor steam and water steam to form a liquor solution and brewing wastewater. In the above treatment method, the steam heat energy is not effectively utilized, wasting heat energy resources, and at the same time increasing the treatment costs of condensed water and wastewater.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] like Figure 1 As shown, the utility model provides a steam recovery control system for the condensation link of liquor distillation.

[0032] Steam recovery control system for the distillation and condensation process of Chinese liquor, comprising a retort 1, a steam inlet pipe 3 and a condenser 18. The steam inlet pipe 3 is connected to the upper part of the retort 1 and the condenser 18, a heat exchange chamber 7 and an expansion compressor 12. A metal diaphragm 9 is provided in the heat exchange chamber 7, and the metal diaphragm 9 divides the heat exchange chamber 7 into upper and lower chambers. The steam inlet pipe 3 is connected to the lower chamber of the heat exchange chamber 7, and the lower chamber is connected to the condenser 18; above the metal diaphragm 9, there is a gas-liquid separation plate 10. The upper chamber of the heat exchange chamber 7 is provided with a water inlet, and the upper chamber is connected to the expansion compressor 12 through a steam outlet pipe 11; the outlet of the expansion compressor 12 is connected to the retort 1 through a bottom pan steam inlet pipe 16, and a bottom pan steam valve 15 is provided on the bottom pan steam inlet pipe 16.

[0033] In this application, by adding a heat exchange chamber 7, the steam heat energy in the production of Chinese liquor can be recovered, significantly saving resources and reducing the waste of resources caused by heat loss; further, the upper chamber of the heat exchange chamber 7 is connected to the expansion compressor 12, and the expansion compressor 12 is connected to the retort 1, so that the recovered heat is used to provide new steam for the system, further saving energy.

[0034] In this embodiment, it also includes a water storage tank 4 connected to the water inlet of the upper chamber. The upper chamber of the heat exchange chamber 7 and the water storage tank 4 are connected through a water inlet pipe 6, and a water inlet valve 5 is provided on the water inlet pipe 6. By adding a water storage tank 4 and a water inlet valve 5, the amount of soft water entering above the metal diaphragm 9 of the heat exchange chamber 7 can be controlled.

[0035] In this embodiment, the expansion compressor 12 is also connected to an energy inlet pipe 14, and an energy inlet valve 13 is provided on the energy inlet pipe 14. By introducing a new air inlet source, it is convenient to further control the steam flow rate entering the retort 1.

[0036] In this embodiment, the upper chamber of the heat exchange chamber 7 is connected to a drain pipe 17, and the drain pipe 17 is added to facilitate the discharge of soft water in the upper chamber.

[0037] In this embodiment, a steam flow sensor 21 is provided in the bottom pan steam inlet pipe 16. By monitoring the steam flow rate entering the retort 1 through the steam flow sensor 21, it is convenient to monitor and adjust.

[0038] In this embodiment, a quality sensor 20 is provided at the bottom of the retort 1 for feedback of the weight of the fermented grains. By monitoring the weight of the fermented grains in the retort 1, it is convenient to calculate the required steam amount and facilitate feedback adjustment.

[0039] In this embodiment, a temperature sensor 2 is provided in the steam inlet pipe 3. By monitoring the temperature of the steam discharged from the retort 1, it is convenient to judge the current stage of the Chinese liquor process, so as to accurately control the required steam.

[0040] In this embodiment, an alcohol detection sensor 19 is provided in the condenser 18 to monitor the alcohol content in the liquid in the condenser 18 so as to judge the current liquor process stage and thus accurately control the required steam.

[0041] In this embodiment, a plurality of fins 8 are connected below the metal diaphragm 9 , and the heat exchange efficiency is improved by adding the fins 8 .

[0042] The steam recovery control system used in the condensation link of liquor distillation mainly includes a steam regeneration unit and an expansion compressor 12. The steam regeneration unit is mainly composed of a heat exchange chamber 7, fins 8, a metal diaphragm 9 and a gas-liquid separation plate 10. The heat exchange chamber 7 is divided into two layers by the metal diaphragm 9, the lower layer is a chamber for steam entry, and the upper layer is a chamber for adding pure soft water. The design is based on the principle of using the heat energy of the lower steam to vaporize the upper soft water to produce pure steam.

[0043] At the beginning of distillation, the wine vapor generated by the steam drum 1 enters the heat exchange chamber 7 at the lower layer of the steam regeneration unit through the steam inlet pipe 3. The heat exchange chamber 7 is provided with fins 8 to form turbulence for the steam and increase the contact area to increase the heat exchange efficiency. The wine vapor transfers heat energy to the upper soft water chamber through the metal diaphragm 9. The soft water chamber is composed of a soft water inlet pipe 6, a drain pipe 17 and a gas-liquid separation plate 10. The soft water passes through the water inlet valve 5 from the water storage tank 4 and is spread on the metal diaphragm 9 to form a thin layer of water film. It absorbs heat and vaporizes to form clean water vapor. The gas-liquid separation plate 10 blocks the water droplets in the steam.

[0044] After the low-pressure steam enters the expansion compressor 12 and is pressurized and heated, it is mixed with the clean high-pressure steam delivered by the energy intake pipe 14, and enters the bottom pot steam pipe 16 through the bottom pot steam valve 15, and is delivered to the bottom pot of the steamer barrel 1 for recycling. The wine vapor passes through the heat exchange chamber 7 of the steam regeneration unit, and the heat is partially utilized to form a gas-liquid combination of wine, which then enters the condenser 18 below and is completely condensed into wine, reducing the condensation cost.

[0045] The mass sensor 20 under the steamer barrel 1 measures the weight of the dregs in real time, and calculates the amount of steam required for the distillation of the steamer wine through the production database, realizing precise control of the steam usage. The wine steam temperature sensor 2 installed on the steam pipe above the steamer cover and the alcohol detection sensor 19 in the wine extraction pipe can be used to judge the downstream wine stage in real time. The steam usage in the tail wine and grain steaming stage is automatically increased according to the preset value, and the corresponding heat exchange efficiency and heat energy recovery efficiency are improved.

[0046] Specifically, the quality sensor 20 feeds back the weight of the mash to match the amount of steam required by the corresponding steamer barrel 1. The disc steamer is used to evenly spread the lees in the steamer barrel 1, and the amount of steam required by the corresponding steamer barrel 1 is matched according to the process requirements. The steam temperature sensor 2, the alcohol detection sensor 19 and the steam flow sensor 21 are used to automatically control the amount of steam passing through the steam valve 15 for the bottom pot. The temperature sensor 2 measures the temperature of the wine in real time, and the alcohol detection sensor 19 measures the alcohol content in real time, and distinguishes the wine flow stage in real time according to the preset value. When the wine temperature exceeds 92°C and the alcohol content is 55%vol, the wine flow stage is automatically switched to the tail wine stage, and the system controls and adjusts the steam valve 15 for the bottom pot. The steam flow sensor 21 detects the amount of steam in the steam pipe for the bottom pot in real time and feeds back to the system. The system automatically identifies the wine flow stage, and realizes heat recovery of different efficiencies according to the steam consumption before and after the tail wine flow. According to the steam demand of different stages of the steamer barrel 1 and the steam volume of the expansion compressor 12, the system automatically controls the energy intake valve 13 to adjust the steam input of the energy center

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
