Problems solved by technology

Since this part of hot water can only be digested by itself for about 40%, the redundant hot water generated after cooling in the hot water temporary storage tank of the saccharification workshop will automatically overflow and be drained after the storage tank is full, causing a lot of waste. The 85°C water in the feeding tank needs to be cooled down to 60°C with cooling water, which still causes waste of energy and water resources

Embodiment 1

[0027] Embodiment one: see figure 1 , figure 2 , a system for reusing cooling hot water in beer production, comprising a hot water temporary storage tank 1 and a feeding pool 3 in a saccharification workshop for containing cooling hot water, the lower end of the hot water temporary storage tank 1 in the saccharification workshop is connected to the feeding pool 3, and The feeding pool 3 is also connected with a cold water inlet pipe 20, and about 40% of the 85°C hot water discharged from the hot water temporary storage tank 1 of the saccharification workshop is provided to the saccharification workshop for feeding, washing and washing. The hot water is mixed with the cold water to form feeding water at 60° C., which enters the feeding tank 3 .

[0028] The side wall of the hot water temporary storage tank 1 in the saccharification workshop is respectively provided with a first overflow pipe 16 and a second overflow pipe 17, wherein the second overflow pipe 17 is higher than ...

Embodiment 2

[0068] Embodiment two: see image 3 , Figure 4 , the numbering is the same as in Embodiment 1, the meaning is the same, the same parts will not be repeated, the difference is: a temperature sensor probe 23 is arranged on the inner side of the hot water storage tank 2 in the boiler workshop, and the temperature sensor probe 9 is connected to the signal input end of the PLC , when the temperature is lower than 65 degrees, the water pump stops working, and the steam inlet valve T2 is opened at the same time, and the signal output terminal of the PLC is connected with the microcomputer (shown in the accompanying drawing) or the digital meter display 24 to display the hot water storage tank of the boiler workshop 2 inside water temperature.

[0069] A temperature sensor probe 25 is arranged inside the hot water storage tank 4 in the bottling workshop, and the temperature sensor probe is connected with the signal input end of the PLC, and the signal output end of the PLC is connec...

Embodiment 3

[0070] Embodiment three: see figure 1 , the number is the same as that of Embodiment 1, and the meaning is the same, and the same parts will not be repeated. The difference is that an overflow pipe 18 is also provided at the upper end of the hot water storage tank 4 in the bottling workshop.

Abstract

The invention relates to a control system for recycling waste heat in beer production, which comprises a saccharification-workshop temporary hot water storage tank, a boiler-workshop hot water storage tank, a boiler-workshop steam tank, a filling pocket, a water pipe and a valve, wherein the lower part of the saccharification-workshop temporary hot water storage tank is communicated with the filling pocket, the upper part of the saccharification-workshop temporary hot water storage tank is communicated with the boiler-workshop hot water storage tank through a first overflow pipe and is communicated with a filling-workshop hot water storage tank through a second overflow pipe, the boiler-workshop hot water storage tank is communicated with the boiler-workshop steam tank, the height of the first overflow pipe is smaller than that of the second overflow pipe, and the height difference is H. The saccharification-workshop temporary hot water storage tank is directly used for supplying filling water into the filling pocket, thus avoiding resource waste caused by discharging residual hot water in the original saccharification workshop, and avoiding troubles and resource waste caused by reheating cold water with steam to serve as the filling water; the residual hot water in the saccharification workshop can be recycled for other fields; and PLC automatic control is adopted to realize automatic and reasonable utilization of the residual hot water, thus the invention is beneficial for popularization and implementation.

Description

1. Technical field: [0001] The invention relates to a waste heat recycling technology in the beer production industry, in particular to a cooling hot water reuse system in the beer production. 2. Background technology: [0002] In the process of producing beer, beer production enterprises will produce a large amount of (85°C) hot water for cooling, and this part of hot water can only be digested by about 40% by itself. Beer production starts with wort. According to the actual situation of most domestic beer production enterprises at present: after the completion of the saccharification process, the hot wort is heat-exchanged through a thin-plate cooler (reverse convection cooling), and the wort enters the fermenter for fermentation and cooling. The water flows into the hot water temporary storage tank placed on the roof of the saccharification workshop. The cooling hot water in the hot water temporary storage tank of the saccharification workshop is currently only used for f...
