Abstract
The invention discloses a coal rod baking method, which adopts methane gas as fuel to bake a coal rod. According to the coal rod baking method, the exhaust gas in the productive process-tail gas produced in the process of hydrogen membrane separation at rear working section, namely the methane gas, is taken as the fuel, so that the unstable problem of moisture in the coal rod caused by the uneven heat distribution in the traditional coal baking technique is solved. As the tail gas produced in the process of hydrogen membrane separation at the rear working section (the methane gas) is recovered to be served as the fuel to bake molded coal, the exhaust gas in the productive process is recovered, a great quantity of heat is recovered, the consumption of feed coal is reduced, and the production cost is saved for enterprises. According to the coal rod baking method, the method is simple, is beneficial for operating and has better effect.
Description
Technical field
The present invention relates to coal rod production technical field, be specifically related to a kind of coal rod furnace drying method.
Background technology
At present, synthetic ammonia feedstock changes coal powder formation into by the piece coal gas, and powdered coal formation comprises that fine coal fragmentation-adding sodium humate macerates the oven dry of system-mechanical presses-coal rod; Wherein supporting coal rod drying system adopts coal-fired oven dry, can not effectively control the intensity of a fire when drying because of fire coal, and entering drying oven heat distribution is inhomogeneous; The coal rod moisture that causes drying oven to make is unstable; And then influence follow-up to be the gasification reaction of fuel with the coal rod, to bring very big influence to production, thereby also cause coal consumption higher.
Summary of the invention
The purpose of this invention is to provide a kind of coal rod furnace drying method.
In order to realize above purpose, the technical scheme that the present invention adopted is: a kind of coal rod furnace drying method, the employing methane gas is a fuel, and the coal rod is dried.
Preferably, said methane gas is carried hydrogen tail gas for back workshop section film.
Coal provided by the invention rod furnace drying method has made full use of the waste gas-back workshop section film that produces in the production process, and to carry hydrogen tail gas namely for methane gas be fuel, solved in traditional coal-fired drying technology because the excellent moisture content instability problem of the coal that the heat distribution inequality causes.Back workshop section film is proposed hydrogen tail gas (namely for methane gas) recovery act as a fuel, both reclaimed the waste gas that produces in the production process, reclaimed a large amount of heats, reduced the consumption of feed coal again, practiced thrift the enterprise production cost as the moulded coal oven dry.Coal rod furnace drying method method provided by the invention is simple, is beneficial to operation, and effect is better.
The specific embodiment
Embodiment 1
The coal rod furnace drying method that present embodiment provides, adopting back workshop section film to carry hydrogen tail gas namely for methane gas is fuel, and the coal rod is dried.
Coal that present embodiment provides rod furnace drying method has made full use of the waste gas-back workshop section film that produces in the production process, and to carry hydrogen tail gas namely for methane gas be fuel, solved in traditional coal-fired drying technology because the excellent moisture content instability problem of the coal that the heat distribution inequality causes.Back workshop section film is proposed hydrogen tail gas (namely for methane gas) recovery act as a fuel, both reclaimed the waste gas that produces in the production process, reclaimed a large amount of heats, reduced the consumption of feed coal again, practiced thrift the enterprise production cost as the moulded coal oven dry.The coal rod furnace drying method method that present embodiment provides is simple, is beneficial to operation, and effect is better.
Claims (2)
1. a coal rod furnace drying method is characterized in that the employing methane gas is a fuel, and the coal rod is dried.
2. coal rod furnace drying method according to claim 1 is characterized in that, said methane gas is carried hydrogen tail gas for back workshop section film.
