Method and device for generating power by utilizing waste gas of matrix-type charcoal kiln

Abstract

The invention discloses a method and a device for generating power by utilizing waste gas of a matrix-type charcoal kiln, wherein the method comprises the steps of: adopting a three-dimensional kiln body and arranging channel groups which are arranged according to matrixes and are provided with two arrays and more than two layers in the kiln body, wherein each channel group is provided with more than one kiln car channel; arranging an entrance lifting movement device which can move kiln cars into a designated kiln car channel in the front of the channel groups; arranging an exit lifting movement device which can move the kiln cars at the kiln car channel exits to a designated position in the back of channel groups; and collecting the waste gas in each kiln car channel together through a flue gas collection main pipe and then obtaining flammable gas by purification treatment, and finally supplying the flammable gas to a generator set for use. By collecting and purifying the waste gas which is discharged in the carbonizing process, the flammable gas is obtained and harmful substances discharged to the air are reduced greatly. Simultaneously, in the purification process of the waste gas, wood vinegar and wood tar can also be extracted as the raw materials of other industries, thus having significant economic benefits.

Description

technical field [0001] The invention relates to a method and device for generating electricity by using exhaust gas, in particular to a method and device for generating electricity by using exhaust gas from an array charcoal kiln. Background technique [0002] The production process of mechanism charcoal is as follows. It uses wood chips and waste plant straw as raw materials. The raw materials are crushed, sieved and then dried. The dried raw materials are made into raw material rods by a rod making machine, and then put on charcoal The finished charcoal is fired in the kiln. During the whole process of making charcoal, a lot of dust and smoke will be produced, also known as charcoal waste gas. In the past, these exhaust gases were directly evacuated, that is to say directly into the atmosphere. These exhaust gases contain a large amount of dust and harmful gases, which cause serious pollution to the atmosphere, so everyone says that the carbon making industry is a major ...
