Automatic laddering water replenishment method

Abstract

The invention relates to an automatic laddering water replenishment method, and belongs to the technical field of automatic ring cold water replenishment. The method comprises the following steps of 1, newly building a ring cold sewage buffer pool and installing an electric water replenishment valve on the pool; 2, setting an automatic water replenishment limit; 3, placing a floating device in thepool; 4, enabling the electric water replenishment valve to start to automatically replenish water when the water level reaches the lower limit; 5, enabling the electric water replenishment valve tostop the automatic water replenishment when the water level reaches the upper limit; and 6, triggering a sound-light alarm when the water level reaches the lower limit without water replenishment andthe water level reaches the upper limit without stopping the water replenishment, and manually opening or closing the electric water replenishment valve to replenish water or stop the water replenishment according to the water level of the floating device. The automatic laddering water replenishment method provided by the invention introduces domestic sewage, reclaimed water and fresh water to thebuffer pool by building a new ring cold sewage buffer pool, and uses the electric water replenishment valve to control the limit of the above three water sources, thereby realizing automatic ring cold water replenishment, solving the problem that fresh water is used for cooling and water spraying always by the ring cold, and reducing the new water consumption of pellets.

Description

technical field [0001] The invention relates to a stepwise automatic water replenishment method, which belongs to the technical field of ring cooling automatic water replenishment. Background technique [0002] As the main equipment of the pelletizing process and sintering process, the annular cooler is a very common cooling equipment, widely used in the cooling of sinter and pellets. The main function has two aspects: blasting and cooling the high-temperature oxidation pellets discharged from the rotary kiln to reduce the temperature to facilitate subsequent processing; as an important part of the heat balance of the whole system, recovering the heat in the high-temperature pellets, Used in the previous process, thereby reducing the fuel consumption of the entire system. [0003] The existing ring cooler uses new water for cooling, which consumes a lot of resources, resulting in a lot of waste of resources, and staff are required to guard during the entire ring cooling pro...

Problems solved by technology

[0004] The purpose of the present invention is to provide a stepwise automatic water supply method. By building a new ring-cooled sewage buffer pool, introducing domestic sewage, reclaimed water, and new water to the buffer pool, and using an electric water supply valve to control the limit of the above three water sources, the ring-cooled automatic water supply can be realized. Water replenishment solves the problem of using fresh water to cool and fetch water for ring cooling, and reduces the consumption of fresh water for pellets; and it has low cost of use, no need for staff to guard, step-by-step water replenishment, and remarkable energy-saving effect
