Description

Parallel connection's buffer memory storehouse

Technical Field

The utility model relates to a parallel connection's buffer memory storehouse for the coal processing field.

Background

China is a country with more coal, less oil and poor gas, and in the petrochemical energy reserves proven in China, oil and natural gas only account for 6 percent, and the rest 94 percent are coal substances. The resource characteristics determine that China mainly builds energy structures by using coal substances.

The DCS System is an english abbreviation (Distributed Control System) of a Distributed Control System, and is also called a Distributed Control System in the domestic automatic Control industry. The computer control system is a novel computer control system relative to a centralized control system, and is developed and evolved on the basis of the centralized control system.

A PLC system, also known as a programmable logic controller, is a digital arithmetic operation electronic system designed specifically for use in an industrial environment. It uses a programmable memory, in which the instructions for implementing logical operation, sequence control, timing, counting and arithmetic operation are stored, and utilizes digital or analog input and output to control various mechanical equipments or production processes.

In the field of coal processing, a large-scale coal processing system is basically controlled by adopting a DCS (distributed control system), distributed management is facilitated, centralized control can be realized, and a common PLC (programmable logic controller) system for a medium-small coal processing system is only required to be controlled in one place in a centralized manner.

At present, a buffer storage bin is generally designed for storing coal at normal temperature, a feeding device and a discharging device matched with the buffer storage bin are also generally normal-temperature devices, and the buffer storage bin is not linked with each other because normal-temperature coal is stored and is also mixed with the normal-temperature coal; however, in the field of coal processing, particularly low-rank coal processing, after low-rank coal processing, particularly after anaerobic or micro-aerobic dry distillation, the hardness is high, and equipment abrasion is more easily caused, the processing temperature of the low-rank coal entering a buffer bin is generally above 100 ℃, the ignition point of the low-rank coal is the lowest ignition point of all coals, is about 270-300 ℃, the stacking time is long, and spontaneous combustion is easily caused under the condition of a certain amount of oxygen. Because current buffer storage storehouse, feed arrangement and discharging device do not record and provide the inside temperature of device, combustible gas concentration and/or pressure, in the coal course of working, DCS system or PLC system control, used data often are for throwing coal processing technology data such as material, owing to lack the inside data of device, make DCS system and PLC system receive the limitation on solving some specific problems, especially on equipment causes the leakage problem because of wearing and tearing, the unusual change of combustible gas concentration in the environment is generally gathered in current DCS system, thereby early warning, consequently, there is higher hysteresis quality.
