Description

Technical Field

[0001] The utility model relates to a heat exchange device, in particular to a waste heat recovery device for a winery. Background Art

[0002] The brewing industry is an important food industry and occupies an important position in the national economy. In the brewing industry, the cooking, fermentation of grains and the distillation of base wine are important links in the brewing process, and these processes consume a lot of energy.

[0003] As we all know, different wines have their own unique flavors and microbial composition. In order to maintain the characteristics of wine, various wines have strict requirements on temperature and pressure during cooking, fermentation and distillation. The cooking and fermentation process of grains is usually carried out in a steamer. The more typical modern cooking process uses steam heating. In order to strictly control the pressure in the steamer, a valve is usually set on the steam inlet pipe of the steamer. The valve is used to adjust the pressure of the steam entering the steamer to ensure that the upper limit of the temperature in the steamer is within a controllable range, while the steam outlet pipe of the steamer is directly connected to the atmosphere to ensure the upper limit of the pressure in the steamer. This steam inlet and outlet control method can ensure the temperature of grain cooking, and then ensure the quality and taste of the wine. However, this steam inlet and outlet control method is relatively extensive, and a large amount of uncondensed exhaust steam directly enters the atmosphere, causing the common problem of excessive steam consumption in wineries. For example, the steam consumption of a winery is about 10 tons / ton of base wine, and there is a lot of room for steam saving. Recovering the waste heat of exhaust steam and reducing steam consumption in the winemaking process are of great significance to reducing winemaking costs and improving the competitiveness of wineries. Summary of the invention

[0004] The purpose of the utility model is to provide a waste heat recovery device for a winery, which recovers the waste heat of steam discharged during the brewing process of the winery, reduces the cost of brewing, and achieves energy saving and emission reduction.

[0005] The technical solution of the utility model is: a waste heat recovery device for a winery, comprising a heat exchanger and a hot water storage tank integrated with heat storage and heating, the heat exchanger is connected in series with the hot water storage tank through a hot water pipe to form an overall waste heat recovery device.

[0006] Furthermore, a hot water valve is arranged on the hot water pipeline.

[0007] Among them, the heat exchanger with integrated heat storage and heating includes an upper head, a lower head and a cylinder. The upper head and the lower head are respectively installed on the upper and lower ends of the cylinder. The upper tube sheet and the lower tube sheet are arranged at the upper and lower ends of the cylinder. Heat exchange tubes are arranged between the upper and lower tube sheets. A cold water inlet pipeline is arranged on the side of the cylinder. A steam inlet is arranged at the bottom of the lower head. The steam inlet is connected to the steam exhaust main pipe of the brewing workshop. A steam exhaust outlet is arranged at the top of the upper head.

[0008] Furthermore, a water inlet valve is arranged on the cold water inlet pipeline.

[0009] Furthermore, a thermometer and a liquid level gauge are arranged on the side of the cylinder.

[0010] Going a step further, a steam trap is installed at the steam inlet.

[0011] The waste heat recovery process of the steam discharged from the brewing workshop is as follows: cold water enters the shell side of the heat exchanger from the cold water inlet of the heat exchanger, and the steam discharged from the brewing workshop enters the tube side through the steam exhaust main pipe through the steam inlet on the lower head of the heat exchanger with integrated heat storage and heating. The steam in the tube side exchanges heat with the water in the shell side, and the cold water in the shell side is heated into hot water. After the water in the shell side is heated to a certain temperature, it enters the hot water storage tank through the hot water pipe between the heat exchanger with integrated heat storage and heating and the hot water storage tank for use by the using department. The steam in the tube side is cooled and condensed into liquid water, and the condensed water is discharged from the steam trap. Part of the uncondensed steam is discharged to the atmosphere through the steam tail gas outlet on the upper head of the heat exchanger with integrated heat storage and heating.

[0012] The utility model has the following features: 1. A liquid level gauge is set on the shell side of the heat exchanger with integrated heat storage and heating to determine the water level on the shell side. 2. A thermometer is set on the shell side. When the cold water on the shell side is heated to a certain temperature, water is supplied to the hot water storage tank according to the needs of the workshop. 3. Since the steaming process and the washing process are intermittent operations, and the exhaust steam and hot water use time are not synchronized, the production of the winemaking workshop is scientifically arranged. 4. There is no valve between the steam exhaust main pipe of the winemaking workshop and the steam tail gas outlet of the waste heat recovery device. The steam exhaust pipeline is unobstructed. While recovering the waste heat, the process operating conditions of the winemaking workshop will not be changed, thereby ensuring the original quality of the wine in the winery.
