TECHNICAL FIELD
[0001] The present application belongs to the field of tail gas recovery, and particularly relates to a high-efficiency tail gas recovery equipment for distilling wine. BACKGROUND
[0002] At present, the treatment method for tail gas of distilling wine in the wine brewing industry is relatively simple and extensive. Most enterprises only directly discharge the tail gas into the atmosphere, and this treatment method has many problems. On the one hand, a large amount of water vapor in the tail gas carries a large amount of heat, and direct discharge will cause serious waste of energy, which does not meet the current development requirements of energy saving and emission reduction. On the other hand, the volatile organic compounds and dust contained in the tail gas will cause serious pollution to the surrounding environment, affect the air quality, and harm human health.
[0003] Some enterprises try to simply treat the tail gas of distilling wine, for example, using an ordinary spray tower for cooling treatment. The low spray tower directly contacts the cooling water with the waste gas for heat exchange to achieve the purpose of cooling, but the effect of recycling the heat in the tail gas is very poor, and most of the heat is lost with the discharge of the cooling water. At the same time, the ordinary spray tower has limited effect on the removal of pollutants in the tail gas, and it is difficult to effectively remove volatile organic compounds and fine dust in the tail gas, so the discharged tail gas after treatment may still be over standard.
[0004] In addition, for the treatment of water vapor in the tail gas, although the existing technology uses condensation, adsorption and other methods to remove water in the waste gas, for example, using a condensing device to reduce the temperature of the waste gas below the dew point to condense water vapor into water and discharge, thereby reducing the humidity of the waste gas, but these water removal methods are usually independently set, and are disconnected with the heat recovery, pollutant removal and other process links of the tail gas, resulting in high equipment complexity, complicated treatment process and high operation cost of the whole tail gas treatment system. Moreover, most of the existing treatment equipment can only treat a specific type of tail gas, and has poor adaptability to tail gas generated by different brewing processes and different raw material ratios, and the application range is limited.

The opening degree of the valve can be adjusted according to the processing progress of the sorghum wine retort, so as to ensure that the cooking and processing of sorghum in the sorghum wine retort are stably carried out.
[0026] The steam compressor TGR forced direct heat exchange circulating device comprises a compressor body and a heat exchange chamber. The gas inlet end of the compressor body is connected with the tail gas outlet of the sorghum wine retort by a pipeline, and is used to receive the tail gas generated by the sorghum wine retort. The gas outlet end of the compressor body is connected with the inlet of the heat exchange chamber. The compressor body can compress the tail gas, so as to increase the pressure and temperature of the tail gas, and facilitate the subsequent heat exchange process. A plurality of heat exchange pipes are arranged in the heat exchange chamber in a spiral manner. The two ends of the heat exchange pipes are respectively connected with the circulating water inlet and the circulating water outlet of the heat exchange chamber. The spiral arrangement of the heat exchange pipes can increase the contact area and contact time of the circulating water and the tail gas, and improve the heat exchange efficiency.
[0027] The circulating water supply system comprises a circulating water tank, a circulating water pump, and a cooling tower. The outlet of the circulating water tank is connected with the circulating water inlet of the heat exchange chamber through the circulating water pump, and the circulating water pump provides power for the flow of the circulating water. The circulating water outlet of the heat exchange chamber is connected with the inlet of the cooling tower.

[0028] The condensing and water removing device is arranged between the steam compressor TGR forced direct heat exchange circulation device and the booster isolation purifier, and comprises a condensing cavity and a water outlet.
