Energy-saving and environment-friendly kiln

Abstract

The invention discloses an energy-saving and environment-friendly kiln. The energy-saving and environment-friendly kiln comprises a sintering section and a smoke discharging section, wherein an air inlet is formed in the sintering section. The energy-saving and environment-friendly kiln is characterized by further comprising a transition section and an exhaust gas induced draft fan. The transition section is connected between the sintering section and the smoke discharging section. An air inlet, a first air outlet and a second air outlet are formed in the exhaust gas induced draft fan, wherein the air inlet extends to the interior of the transition section, the first air outlet is communicated with the air inlet of the sintering section through an exhaust gas backflow pipe, and the second air outlet extends to the smoke discharging section. The energy-saving and environment-friendly kiln has the advantages of being simple and reasonable in structure, capable of balancing the air pressure on the smoke discharging section, and capable of recycling the exhaust gas, improving thermal efficiency, reducing energy consumption, and being energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of kilns, in particular to an energy-saving and environment-friendly kiln. Background technique [0002] At present, the improvement of various kilns has been studied on how to reduce heat loss. For example: ceramic kiln, its structure includes a firing section and a smoke exhaust section. The high-temperature exhaust gas generated in the firing section is directly discharged from the furnace body through the smoke exhaust section. [0003] The traditional kilns mentioned above have the following deficiencies: (1) Since the exhaust gas has high heat, the high-temperature exhaust gas is directly discharged in this way, which obviously causes waste of heat, affects thermal efficiency, and loses heat energy; moreover, the kiln is in use At the same time, a rated amount of heat is required, and the direct discharge of high-temperature exhaust gas will consume more heat energy. To make up for the lost heat, more...

Problems solved by technology

[0003] The traditional kilns mentioned above have the following deficiencies: (1) Since the exhaust gas has high heat, the high-temperature exhaust gas is directly discharged in this way, which obviously causes waste of heat, affects thermal efficiency, and loses heat energy; moreover, the kiln is in use At the same time, a rated amount of heat is required, and the direct discharge of high-temperature exhaust gas will consume more heat energy. To make up for the lost heat, more energy will be consumed, which will inevitably cause more exhaust gas emissions, pollute the environment, and increase Production cost; (2) The exhaust gas from the firing section all enters the smoke exhaust section. However, due to the inability to balance the air pressure in the exhaust chamber, it will affect the timely discharge of exhaust gas, thereby affecting the firing quality of the product
