Abstract

A feeder of a coal low-temperature pyrolysis reactor comprises a tank, the upper portion of the tank is provided with a coal inlet, a discharge outlet arranged at one end of the tank body is connected with a feed inlet of the reactor, and a feeding device capable of conveying raw coal briquettes to the reactor and a catalyst spraying pipe used for spraying catalyst and communicated into the reactor are arranged in the tank. Nanometer catalyst can be directly sprayed into the reactor by the catalyst spraying pipe arranged in the feeder of the coal low-temperature pyrolysis reactor, so that the catalyst and volatile matters can be sufficiently mixed in the reactor, and pyrolysis efficiency can be improved greatly.

Description

technical field [0001] The invention belongs to the technical field of coal heating and cracking, and in particular relates to a feeder for a coal low-temperature pyrolysis reactor. Background technique [0002] Coal thermal cracking (coal dry distillation, coal pyrolysis) is one of the important processes of coal chemical industry. It refers to the process in which coal is heated and decomposed under air-isolated conditions to produce coke (or semi-coke), coal tar, crude benzene, gas and other products. According to the difference in the final heating temperature, it can be divided into three types: 900-1100°C is high-temperature pyrolysis (high-temperature dry distillation), that is, coking; 700-900°C is medium-temperature pyrolysis; 500-600°C is low-temperature pyrolysis. [0003] At present, the low-temperature pyrolysis of coal generally adopts the internal heat method of solid heat carrier. The method firstly mixes the preheated small pieces of raw coal with the cata...
