Abstract

The method for preparing ice water at 1-2 deg.C solves the problems that in industrial production, low-temperature pure water at 1-2 deg.C is used for feeding material, and the transport of pump is affected due to no ice formation. At present, ice water at 1-2 ℃ is prepared in industrial production, most of the ice water is prepared by firstly preparing low-temperature antifreeze solution and then carrying out plate exchange and secondary exchange with pure water, and also a coil pipe is added in the water tank to lead refrigerant to the coil pipe to cool the water in the water tank to 1-2 ℃, and the water in the water tank is continuously stirred to prevent ice.

Description

Method for preparing ice water at 1-2 DEG C
Technical Field
The invention relates to the field of refrigeration, in particular to the field of preparing ice water at 1-2 ℃.
Background
In industrial production, a plurality of processes need to be carried out by feeding pure water at a low temperature of 1-2 ℃ and the transmission of a pump is not influenced by freezing, most of the current processes adopt a method of firstly preparing low-temperature antifreeze fluid and then carrying out plate exchange and secondary exchange with pure water, and also adopt a method of adding a coil pipe into a water tank and introducing a refrigerant into the coil pipe to cool the water in the water tank to the temperature of 1-2 ℃ and continuously stirring the water in the water tank to prevent freezing, and the two methods need to additionally add matched auxiliary equipment and are not energy-saving.
Disclosure of Invention
The invention adopts the mode of repeated circulation in the front section and one-time cooling in the rear section, and realizes the preparation of ice water at 1-2 ℃ by the optimized control method, thereby avoiding freezing, having less equipment initial investment, being simple to control and saving energy.
The specific method comprises the following steps: the refrigerating system is provided with two water tanks, namely a raw water tank, an ice water tank, a small raw water tank and a large ice water tank, wherein the ice water tank is provided with a liquid level sensor, a water outlet of the refrigerating unit is provided with a temperature sensor and a steering device, and the switching device can be respectively provided with an electric valve on a branch pipeline leading to the raw water tank and the ice water tank or a three-way reversing electric valve on a Y-pipe leading to the raw water tank and the ice water tank. The automatic water replenishing device is composed of a liquid level sensor and a water replenishing valve, when the water level of the original water tank is lower than a certain scale, water replenishing is automatically stopped when the water level of the original water tank is higher than the certain scale, a refrigerating unit, a pump, a pipeline, a valve and the original water tank form a refrigerating loop when the water temperature of the original water tank is higher, the refrigerating unit firstly cools the water in the original water tank in a circulating way, when the water temperature of the original water tank is reduced to a certain temperature, the water of the original water tank enters the evaporator of the refrigerating machine to be cooled to 1-2 ℃ in a one-stage way mode, when the water temperature sensor at the water outlet of the refrigerating unit detects that the water temperature is lower than 2 ℃, the steering device automatically steers to enable ice water to enter the ice water tank, if a small amount of ice is formed in the evaporator at the moment, but ice is melted rapidly again because the high-temperature water in the original water tank continuously enters the evaporator, and therefore ice blockage cannot be generated. When the water level of the original water tank is reduced to a certain scale mark, new normal-temperature water is filled into the original water tank, the temperature of the original water tank is increased, and when the water temperature sensor detects that the water temperature is higher than 2 ℃, the steering device is automatically switched to repeatedly cool the water in the original water tank.
A liquid level sensor is arranged in the ice water tank, and when the liquid level of the ice water tank reaches a certain height, the system is automatically stopped; when the liquid level of the ice water tank is lower than a certain height, the system is started again; when the liquid level in the ice water tank is reduced to a certain limit height, the external ice water supply pump stops supplying ice water to the production line.
The refrigerator evaporator is preferably plate-exchanged, and the evaporating temperature of the plate-exchanged evaporator is relatively high when the same water outlet temperature is obtained, so that the icing risk is further reduced.
Advantageous effects
By adopting the mode, the freezing risk of the refrigerator can be effectively reduced, and auxiliary equipment matched with the refrigerator is reduced. The front section adopts a circulating cooling mode, so that the instant evaporation temperature of the refrigerator is improved, and the refrigeration energy efficiency is improved.
