Problems solved by technology

A single low-temperature temperature control unit can fully satisfy the cycle temperature control and heat preservation work for two material tanks. However, once a single low-temperature temperature control unit fails or is repaired and maintained, it will have a direct impact on production

Abstract

The invention discloses a double-tank double-temperature-control redundant hot-standby low-temperature control system which comprises a first tank, a first low-temperature control unit, a second tank and a second low-temperature control unit. The invention also discloses a control method of the double-tank double-temperature-control redundant hot-standby low-temperature control system. The control method is carried out according to eight working modes and four steps and has very high fault-tolerant performance. The failure of any single device does not affect the normal operation of the system. The eight working modes can be automatically switched for the control system, and regular timing switching can make the components of the system used so as to avoid negative effect on the device due to long-term idle. The control system may automatically switch in failure and may solve problems in most case cases by using own fault-tolerant performance of the system, greatly reduces the number of manual intervention times, reduces labor intensity, and improves the operation efficiency and the degree of automation.

Description

technical field [0001] The invention relates to a temperature control structure and a control method of a spice heating tank. Background technique [0002] In the actual production process of the tobacco industry, the spice heating tank mostly adopts the method of double-tank circulation temperature control, which not only effectively improves the production efficiency, but also avoids the failure of the material tank to affect the production. Low temperature temperature control system (also called low temperature heating system) is a system that uses circulating hot water or circulating cold water to control the temperature (heating or cooling) of the liquid in the tank. [0003] In order to distinguish it from the dual temperature control redundant hot standby low temperature temperature control system of the present invention, the existing low temperature temperature control system is called a low temperature temperature control unit. [0004] With the progress of societ...
