Intelligently controlled coal coking smoke waste heat recovery system

Abstract

The invention discloses an intelligently controlled coal coking smoke waste heat recovery system. The system comprises a gas guiding tube used for connecting and introducing coal coking smoke, the gas outlet end of the gas guiding tube communicates with a buffer chamber, one end, close to the gas guiding tube, in the buffer chamber is detachably provided with a buffer rack, the buffer rack is provided with a plurality of ceramic buffer balls, the gas outlet end of the buffer chamber communicates with a heat recovery chamber, a coal economizer is arranged in the heat recovery chamber, the water inlet end of the coal economizer traverses through the heat recovery chamber and is externally placed below the heat recover chamber, the water outlet end of the coal economizer traverses through the heat recovery chamber and is externally placed at the top of the heat recovery chamber, and the gas outlet end of the heat recovery chamber is connected with a gas outlet tube; and the system also comprises a controller, a first solenoid valve is arranged between the buffer chamber and the heat recovery chamber, a second solenoid valve is arranged between the heat recovery chamber and the gas outlet tube, a temperature sensor and a pressure sensor are arranged at the middle part of the heat recovery chamber, and the first solenoid valve, the second solenoid valve, the temperature sensor and the pressure sensor are respectively electrically connected with the controller.

Description

technical field [0001] The invention relates to the technical field of heat recovery systems, in particular to an intelligent control briquette coking flue gas waste heat recovery system. Background technique [0002] Coal coking, also known as coal high-temperature dry distillation, is a coal conversion that uses coal as raw material, heats coal to about 950°C under air-isolated conditions, produces coke through high-temperature dry distillation, and simultaneously obtains gas and coal tar and recovers other chemical products. craft. During the entire coal conversion process, some high-temperature flue gas and waste gas will inevitably be produced, and these flue gases will take away a large amount of heat energy, which will cause a great waste of energy. At present, various new types of energy-saving equipment have been continuously developed, such as the use of high-quality insulation materials such as new refractory fibers, so that the heat loss of coal conversion equip...

Problems solved by technology

However, the flow rate of high-temperature flue gas is relatively fast. Most of the flue gas flowing at high speed in the prior art has not been slowed down. The flue gas that quickly brushes through the cooling liquid pipe has insufficient heat energy recovery and low heat recovery efficiency.
