A heating equipment for coal chemical deep processing

Abstract

The invention relates to coalification deep processing heating equipment. The coalification deep processing heating equipment is characterized in that a cavity below a driving fire grate is divided into an area A, an area B and an area C by a separating board AB and a separating board BC, an area A air adjusting push-pull rod is arranged in the area A, an area A air door is arranged on the separating board AB opposite to the area A air adjusting push-pull rod, a double-bottom air channel is arranged below the area A, a fan connecting port is formed outside the area A, a coal inlet, a front furnace arch, a middle furnace middle arch and a rear furnace arch are arranged above the driving fire grate, heat insulating materials are arranged above the middle furnace arch, the outside of the rear furnace arch is communicated with an ash cleaning port, a fire wall is arranged in a purification room, a flame path is arranged outside the purification room, and a distillation still outer wall is arranged outside the flame path. The coalification deep processing heating equipment has the advantages that rolling wheels are arranged on the bottom portion of the coalification deep processing heating equipment, the coalification deep processing heating equipment is convenient to move, and the coalification deep processing heating equipment is small in size, small in occupied area, unique in air distribution mode, strong in coal type adaptability, sufficient in coal seam burning, low in carbon content of ash, stable in heating system, convenient to maintain and capable of solving the problems of large coal consumption of an industrial furnace, poor working conditions and the like well.

Description

technical field [0001] The invention relates to a heating equipment for deep processing of coalification. Background technique [0002] my country is a big coke producer, accounting for about 36% of the world's total. The production of coke produces a large number of by-products-coal tar. Coal tar is an organic mixture mainly composed of aromatic hydrocarbons. It contains more than 10,000 compounds, and about 200 types can be extracted. The light oil, phenol, and naphthalene obtained by its deep processing , asphalt and other products are the basic raw materials for synthetic plastics, synthetic fibers, pesticides, dyes, medicines, coatings, additives and fine chemical products, as well as basic raw materials for metallurgy, synthesis, construction, textiles, papermaking, transportation and other industries. Therefore, coal The development of tar deep processing can greatly promote the development of these industries. [0003] However, there are two kinds of heating condit...

AI Technical Summary

Problems solved by technology

[0003] However, there are two kinds of heating conditions for the deep processing of coal tar today, one is gas heating, and the other is coal-fired heating. The gas generator required for gas heating is expensive, and it is a pressure vessel, which is complicated to operate and dangerous, so it is used Most coal-fired heating methods are used, but the external air ducts of coal-fired machinery used for coal-fired heating occupy a large area, and the operating space for the fireman is small, and it is inconvenient to add coal and slag. The air volume on the opposite side of the tuyere air chamber is large, and the local wind pressure on the combustion surface is too large. On the other side, the air volume is small, the air supply is insufficient, and the fuel combustion is insufficient. In addition, the old-fashioned equipment must be shut down for maintenance. In the end, maintenance personnel can enter the kiln to replace accessories for maintenance work, resulting in many problems for users in terms of environmental protection, energy saving and consumption reduction.
