Rotary cooling furnace for semi-coke dry quenching

Abstract

The invention discloses a rotary cooling furnace for semi-coke dry quenching. The rotary cooling furnace comprises a furnace body, wherein a plurality of rolling rings are arranged on the furnace body; the rolling rings are respectively supported by support wheel devices and baffle support wheel devices; a transmission device for driving the furnace to continuously rotate on the support wheel devices and the baffle support wheel devices is arranged outside the middle section of the furnace body; a feeding mechanism and a material feeding seal are arranged at the head of the furnace body; a water spraying cooling jacket is arranged at the front section of the furnace body; a discharge mechanism is arranged outside the rear section of the furnace body; a fish scale sealing structure is arranged between the furnace body and the discharge mechanism; the furnace body is internally provided with a cooling system; the cooling system is communicated with a rotating connector at the tail part of the furnace body; semi-coke is fed into a cooling zone in the furnace body through the feeding mechanism; through circulation water heat exchange in a cooling system tube bundle, indirect cooling quenching of the semi-coke in the furnace body is completed. By adopting the rotary cooling furnace, the semi-coke is continuously and indirectly cooled, so that the semi-coke barely has moisture, the quality of the semi-coke is improved, the environment can be protected, the energy can be saved, and the semi-coke does not need to be further dried by a user when being used.

Description

technical field [0001] The invention relates to a rotary cooling furnace for dry-cooling and quenching semi-coke (semi-coke) during the production process of industrialized semi-coke (semi-coke). Background technique [0002] Semi-coke, also known as semi-coke, can be widely used in production and living fields such as calcium carbide, ferroalloy, fertilizer gas production, blast furnace injection, and clean coal for urban residents; while producing semi-coke (semi-coke), by-products of tar and coke oven gas. At present, the main method for industrial production of semi-coke (semi-coke) in China is the thermal cracking of internal heating type vertical carbonization furnace to prepare semi-coke. This process mainly adopts water-sealed wet coke quenching for semi-coke (semi-coke) cooling treatment. [0003] At present, the domestic industrial production of semi-coke (semi-coke) is the most widely used, largest-scale, and most-used method of pyrolyzing raw coal to prepare se...

Problems solved by technology

[0003] At present, the domestic industrial production of semi-coke (semi-coke) is the most widely used, largest-scale, and most-used method of pyrolyzing raw coal to prepare semi-coke is thermal cracking of internal heating vertical carbonization furnace to prepare semi-coke. This process cools semi-coke (semi-coke) The water seal wet coke quenching method is mainly used in the treatment. This coke quenching method will produce a large amount of high-temperature wastewater and steam during coke quenching, and the harmful components contained in the wastewater and steam will pollute the environment. At the same time, the coke quenching process consumes The latent heat of a part of semi-coke (semi-coke) affects the quality of semi-coke (semi-coke), restricts the use of semi-coke, and the product has a high water content, which increases transportation costs. Users need to re-dry when reusing
