Exhaust gas recycling system for garbage brick factory

Abstract

The invention relates to an exhaust gas recycling system for a garbage brick factory. The exhaust gas recycling system comprises a kiln body and a closed garbage green brick producing workshop, wherein the kiln body is divided into a green brick drying section, a furnace section and a finished brick cooling section sequentially, a first air outlet is arranged on the green brick drying section, a first air inlet and a second air inlet are arranged on the finished brick cooling section, and a second air outlet is arranged on the closed garbage green brick producing workshop; a first fan is installed on the first air outlet, a first ventilation pipeline through which the first fan is communicated with the finished brick cooling section is installed on the first fan, and a dust remover, an oxygenation device and a first control valve are arranged on the first ventilation pipeline; a second fan is installed on the second air outlet, a second ventilation pipeline through which the second fan is communicated with the finished brick cooling section is installed on the second fan, and a second control valve is arranged on the second ventilation pipeline. According to the exhaust gas recycling system, repeated combustion of monoxide such as carbon monoxide in exhaust gases can be achieved, so that exhaust emissions are reduced, the utilization rate of fuel is improved, energy conservation and emission reduction are achieved; the exhaust gas recycling system has the advantages of being simple in structure, convenient to use and popularize and capable of achieving energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a waste treatment system, in particular to a recycling system for waste gas from a waste brick factory. Background technique [0002] With the continuous development of our society and the continuous improvement of people's living standards, in order to adapt to people's rapidly improving living standards, the country, enterprises and individuals have invested more and more in infrastructure construction. An important part of construction, greening and infrastructure for municipal engineers. These basic constructions are inseparable from bricks in the construction process. The current bricks can be divided into unburned bricks and fired bricks according to the manufacturing method. However, due to the low strength and short service life of unburned bricks, they are generally used The filling bricks used in large-scale retarded concrete frame structur...

These basic constructions are inseparable from bricks in the construction process. The current bricks can be divided into unburned bricks and fired bricks according to the manufacturing method. However, due to the low strength and short service life of unburned bricks, they are generally used The filling bricks used in large-scale retarded concrete frame structure buildings have a narrow range of use; while fired bricks can be widely used in various construction fields due to their advantages such as high strength and long service life, and now fired bricks still occupy the most of the market for bricks

In the production process of fired bricks, it must first be made from garbage, and then fired through the kiln body. During the firing process of garbage bricks, the kiln body will generate a large amount of waste gas. The waste gas contains carbon dioxide, nitrogen dioxide, Sulfur dioxide, carbon monoxide, nitrogen monoxide, dioxins and other gases, of which carbon dioxide and nitrogen dioxide are the main gases that cause the greenhouse effect, sulfur dioxide will cause rainwater and air acidification, and carbon monoxide, nitrogen monoxide, dioxins are not only harmful to the human body It is a toxic gas that is seriously harmful, and it is still a gas that can be burned again. Therefore, once these gases are discharged into the air, they will not only cause great harm to the environment and the human body, but also cause a waste of resources; The billet workshop will also produce some exhaust gas during the billet making process, especially the workshop that uses garbage to make billets, which will produce unpleasant odors. The current treatment method is to extract the odor gas into the air through an air extractor, so that cause air pollution
