Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail

[0018] figure 1 Among them, the gas collection chamber (1) is located at the charging end of the coking furnace and communicates with the tubular carbonization chamber (3), and the top of which is provided with a gas collection pipe (4) for collecting the charging of the coking furnace and during the carbonization process. A small amount of overflowing gas is sent to the combustion chamber (2) as fuel, and the gas collection chamber (1) has a hole corresponding to the size of the tubular carbonization chamber (3), and is equipped with a movable valve. The charging device is loaded into the tubular carbonization chamber (3) through the gas collection chamber (1), and at the same time pushes the carbonized coke into the coke discharge chamber (6).

[0019] The tubular carbonization chamber (3) consists of a plurality of pipes arranged from top to bottom to...

Abstract

The invention discloses a tubular coking furnace, which is characterized in that the tubular carbonization chamber is composed of more than two pipes arranged from top to bottom, a combustion chamber is formed between the carbonization chambers, and the inlet and outlet of the carbonization chamber are respectively connected with the collector. The gas chamber is connected with the coke discharge chamber; one end of the coke discharge chamber is connected with the tubular carbonization chamber, the other end is provided with a discharge gate connected with the coke quenching chamber, and the upper gas outlet is connected with the gas pipeline; There is a gas collection chamber connected with the carbonization chamber, and the top is provided with a gas collection pipe connected to the combustion chamber to close the feed end; the coke discharge chamber at the discharge end is connected to the coke quenching chamber, and an arched gate is set in between, and the coke quenching chamber passes through the coke quenching water tank Close the discharge end with the water gas collection port. The invention implements a fully enclosed structure for feeding and discharging materials, which completely eliminates the pollution problem in the production process of molded coke. The coking quality of the molded coke is improved, and the structure is simple, the range of raw materials is wide, and the cost of coking is low, so it is suitable for coking of various molded coals.

Description

technical field [0001] The invention relates to a coke oven device composed of a carbonization chamber-combustion chamber heat exchange structure, in particular to a tubular coke oven used for coke production. Background technique [0002] The research on molded coke in foreign countries began in the 1950s. The types of molded coke ovens include: sand bath furnace, vertical furnace, oxygen heat treatment in tunnel kiln, inclined bottom carbonization furnace, etc. [0003] Since the early 1980s, we have been developing and applying coke. He has researched and developed tunnel kilns, rotary hearth furnaces, inclined groove furnaces, rotary furnaces, vertical furnaces and inclined hearth furnaces, and gained certain experience. The practical application effects are more prominent in the following three types: [0004] (1) Fifty tons of "rapid coking coke" carried out in the 1980s were produced in batches for industrial testing of fertilizer gas production. In December 1983, ...
