Low-temperature coal carbonization kiln

Abstract

The invention discloses a low-temperature coal dry distillation square furnace, which comprises a furnace body, a coal scuttle, a coke pusher, and a branch pipe mixer. A gas-collecting array umbrella is installed on the top of the furnace chamber. The lower part is provided with several rows of air-distributing flower walls, and each row of air-distributing flower walls corresponds to the interval between every two adjacent parasols of the air-collecting array umbrella, and the two adjacent rows of air-distributing flower walls are supported by bow-shaped walls; each row of air-distributing flower walls Two branch pipe mixers are inserted on the front and rear sides; a coke discharge box is connected to the lower end of the furnace body, a coke guide groove is connected under the coke discharge box, a coke pusher is arranged under the coke guide groove, and a coke pusher plate of the coke pusher is installed A water seal tank, a scraper machine is arranged in the water seal tank. The present invention adopts internal combustion and internal heat heating scheme, and the heating is uniform. The gas-collecting array umbrella and auxiliary coal box are used to make the cloth evenly and collect gas evenly. The coke pushing mechanism is used to make the discharge uniform. Therefore, the maximum production capacity is fully utilized, the investment is reduced, the benefit is improved, it is easy to operate, employs less people, and can realize automatic control.

Description

technical field [0001] The invention relates to a dry distillation furnace, in particular to a coal low-temperature dry distillation square furnace. Background technique [0002] The original carbonization furnace is a vertical cavity with the same width, and a heating combustion chamber is arranged on both sides of the vertical cavity, and the heating gas is injected into the vertical cavity after being burned at a high temperature in the combustion chamber. The existing problem is: the high temperature gas enters the furnace, the temperature is not easy to control, it is easy to cause the coal to ash and hang slag due to the high temperature, which affects the service life of the furnace, and affects the output and quality of the product. Moreover, the volume of the vertical cavity is small, and the output is also very low. Contents of the invention [0003] In order to solve the above-mentioned existing problems, the object of the present invention is to provide a low-...
