Embodiment Construction

[0020] Below in conjunction with accompanying drawing, system and method of the present invention are described in further detail:

[0021] Please refer to figure 1 , The present invention includes pulverized coal pyrolysis system A, coke powder molding system B and others. The pulverized coal pyrolysis system A is equipped with a synthesis gas outlet, a coke powder outlet and a coal tar outlet, and the coke powder and coal tar outlets are connected to the coke powder forming system B inlet. The coke powder forming system B is provided with a crude gas outlet connected to the pulverized coal pyrolysis system A, and a briquette outlet. The briquette outlet is divided into two paths, which are respectively connected to the carbonization furnace 9 and the inlet of the water bath chain bucket cooler 11.

[0022] The pulverized coal pyrolysis system A includes a pulverized coal pyrolysis furnace 1 , a cyclone separator 2 , a gas cooler 3 and an oil-water separator 4 . The pulveri...

Abstract

The invention discloses a system and a method for producing coal briquette and formed coke through pyrolysis coke powder comprehensively and efficiently. The system comprises a powdered coal pyrolysis system and a coking coal molding system, wherein the powdered coal pyrolysis system comprises a powdered coal inlet, a synthesis gas outlet, a hot coke powder outlet as well as a coal tar outlet, part of the synthesis gas of the synthesis gas outlet is taken as outer supply, and the other part is taken as the heat source of the powdered coal pyrolysis system, the hot coke powder outlet and the coal tar outlet are connected with the inlet of the coking coal molding system, the outlet of the coking coal molding system comprises a raw gas outlet and a coal briquette outlet, and the raw gas outlet is connected with the powdered coal pyrolysis system.

Description

technical field [0001] The present invention relates to the technical field of molded coal and molded coke in the direction of coal chemical industry, especially the technical field of coke powder forming after medium-low temperature pyrolysis of pulverized coal, and specifically relates to a system and method for comprehensively and efficiently producing molded coal and molded coke from pyrolysis coke powder . Background technique [0002] According to the heating method, the traditional hot pressing forming process can be divided into two categories: gas heat carrier rapid heating hot pressing forming process and solid heat carrier rapid heating hot pressing forming process. The IGI process of the former Soviet Union is a typical gas heat carrier process. It needs to consider the combustion efficiency of the hot blast stove and the heat transfer efficiency between gas and solid phases. The Ancit process in Germany is a typical solid heat carrier process. It uses a certain...
