Abstract

The invention relates to a control device used for the coal dry distillation process and a control method thereof, and is used for a coal dry distiller having a pipeline for transporting gas, air and recycle gas. The control device has a heat carrier temperature control part and a material terminal temperature control part. According to the control device used for the coal dry distillation process, the heat carrier temperature control part is realized by the mode of gas distribution, i.e. two gases enter into a mixing chamber simultaneously, wherein one is high temperature flue gas generated by gas and air through combustion, and the other is recycle gas (the drying section is flue gas and the dry distillation section is raw gas) through heat exchange. A temperature sensor and a pressure sensor are arranged in the mixing chamber for providing feedback signals. The amount of recycle gas is increased if temperature is high and the amount of recycle gas is decreased if temperature is low so that operation is convenient and flexible, the control device can be rapidly adapt to the change of temperature and realization of automatic control is facilitated.

Description

technical field [0001] The invention relates to the technical field of coal treatment equipment, in particular to a control device and a control method for a coal dry distillation process. Background technique [0002] The dry distillation of coal is a reaction process in which solid or organic matter is heated and decomposed in the absence of air. As a result of dry distillation, various gases, vapors and solid residues are produced. The mixture of gas and vapor is separated into gas and liquid after cooling. Dry distillation is a production process that humans have been familiar with and adopted for a long time, such as dry distillation of wood to make charcoal, and at the same time to obtain wood essence (methanol), wood acetic acid, etc. Dry distillation has always been an important method in the chemical processing of coal. After the coal is dry-distilled, the composition and aggregation state of the raw materials will change, and there are solid, gaseous and liquid ...
