Roller kiln oxidation section double-flue heat exchange system

Abstract

The invention discloses a roller kiln oxidation section double-flue heat exchange system which comprises a kiln body, the interior of the kiln body is divided into an oxidation chamber and a flue chamber, the two sides of the kiln body are provided with a first energy-saving combustor and a second energy-saving combustor corresponding to the oxidation chamber respectively, the top of the kiln body is provided with a vertical frame, and a main air pipe is installed on the vertical frame; and a flow dividing pipe is arranged at the bottom of the kiln body, a branch air pipe is communicated between the main air pipe and the flow dividing pipe, a first pipeline connector and a second pipeline connector are arranged at the two ends of the flow dividing pipe respectively, a first heat exchange pipe communicated with the first energy-saving combustor is arranged on the first pipeline connector, and a second heat exchange pipe communicated with the second energy-saving combustor is arranged on the second pipeline connector. After the main air pipe is ventilated, air reaches the flow dividing pipe along the branch air pipe and then enters the first heat exchange pipe and the second heat exchange pipe in a flow dividing mode, heat exchange with the flue chamber is achieved, high-temperature gas is conveyed to the energy-saving combustors to be mixed with fuel gas, the energy-saving combustors can ignite only by consuming little energy, and then the effects of saving energy and reducing consumption are achieved.

Description

Technical field [0001] The present invention relates to the field of kiln, and more particularly to a two-fling heat exchange system for roller cauling sections. Background technique [0002] In recent years, the construction ceramic industry has become more strict in national environmental protection requirements. The supply of raw materials is tight, electricity, gas price increase, product cost is getting higher and higher. The profits of corporate profits are further compressed. The product market competitiveness has continued to decline in the severe situation, in order to Enterprise survival and development, reduce production costs, and energy saving and consumption reduction are imperative. In the construction ceramic production process, the fire of the wall brick is achieved by gas burning roller kiln. Gas-burning roller kiln is one of the main equipment of electricity and gas consumption in ceramic production enterprises. How to make the gas burning roller kiln can ensur...
