Description

Technical Field

[0001] The utility model relates to the technical field of alcohol waste heat recovery, in particular to an alcohol finished product waste heat recovery device. Background Art

[0002] In my country, alcohol production enterprises use a large amount of cooling water to cool the finished alcohol to below 35°C after the finished alcohol is produced and then send it to the tank area for storage. The cooling process requires the installation of multiple sets of cooling equipment and consumes a large amount of cooling water. In addition, in the hot summer season, the cooling water temperature is high and the cooling water often fails to cool down, causing alcohol production enterprises to reduce production.

[0003] Cooling of finished products in the alcohol industry is a long-standing problem. Due to the difficulty and high cost of recovering low-quality heat, this heat can only be removed through cooling water, resulting in a waste of low-grade energy. Utility Model Content

[0004] The purpose of the utility model is to provide a waste heat recovery device for finished alcohol products to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waste heat recovery device for finished alcohol products, comprising an alcohol condenser, a split heat pipe heat exchange component, a lithium bromide absorption refrigerator, an alcohol cooler and an alcohol final cooling device, wherein two split heat pipe heat exchange components are provided, the alcohol condenser is connected to one end of the lithium bromide absorption refrigerator through one of the split heat pipe heat exchange components, and the other end of the lithium bromide absorption refrigerator is connected to the alcohol cooler through another split heat pipe heat exchange component.

[0006] A steam inlet is arranged at the top of the alcohol condenser, and the bottom of the alcohol condenser is connected with the alcohol cooler through a pipeline.

[0007] One side of the alcohol cooler is connected to the alcohol final cooling device through a pipeline 2.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. The utility model can reduce the amount of circulating water for cooling finished alcohol products and avoid wasting water resources.

[0010] 2. The utility model recycles waste heat and generates chilled water which is added to the circulating water pool, further increasing the cooling capacity of the circulating water system in summer.

[0011] 3. The utility model can ensure production in the high temperature season in summer and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1 The utility model provides a technical solution: a waste heat recovery device for finished alcohol products, comprising an alcohol condenser 1, a split heat pipe heat exchange component 2, a lithium bromide absorption refrigerator 3, an alcohol cooler 4 and an alcohol final cooling device 5, wherein two split heat pipe heat exchange components 2 are provided, the alcohol condenser 1 is connected to one end of the lithium bromide absorption refrigerator 3 through one of the split heat pipe heat exchange components 2, and the other end of the lithium bromide absorption refrigerator 3 is connected to the alcohol cooler 4 through another split heat pipe heat exchange component 2.

[0016] A steam inlet is provided at the top of the alcohol condenser 1, and the bottom of the alcohol condenser 1 is connected to the alcohol cooler 4 through a pipeline 1.

[0017] One side of the alcohol cooler 4 is connected to the alcohol final cooling device 5 through a pipeline 2.

[0018] The process of this device is as follows:

[0019] The finished alcohol vapor extracted from the finished product is first condensed by the alcohol condenser 1, and the latent heat of vaporization of the alcohol is sent to the lithium bromide absorption refrigerator 3 through the split heat pipe heat exchange component 2 to provide energy for refrigeration.

[0020] After condensation, the hot alcohol product transfers part of its heat to the lithium bromide absorption refrigerator 3 through the alcohol cooler 4, so that the temperature of the alcohol drops to 85°C, and finally the finished product temperature is cooled to 35°C through the alcohol final cooling device 5.

[0021] The recovered heat passes through the split heat pipe heat exchange assembly 2 and is used as the energy source of the lithium bromide absorption refrigerator 3, and the produced low-temperature chilled water returns to the circulating water pool.
