Spiral self-preheating deodorization furnace and waste gas deodorization process using same

Abstract

The invention provides a spiral self-preheating deodorization furnace and waste gas deodorization process using the same. The spiral self-preheating deodorization furnace comprises an inner cylinder, an outer cylinder and a spiral guiding plate. The outer cylinder comprises a preheating chamber and a combustion chamber. The top portion of the inner cylinder is communicated with the combustion chamber of the outer cylinder. The spiral guiding plate is arranged on an outer wall of the inner cylinder in spiral mode from the bottom to the top. A waste gas inlet is arranged at the bottom side of the outer cylinder. The waste gas inlet is communicated with the preheating chamber. A gas inlet is arranged on the top side of the outer cylinder. The gas inlet is communicated with the combustion chamber. The gas inlet is tangential with an outer wall of the combustion chamber. A waste gas outlet is communicated with the bottom of the inner cylinder. The spiral self-preheating deodorization furnace can adapt to deodorization processing of different foul gas substances with high concentration and large gas quantity, is stable and reliable in operation and does not require special pre-processing, such as heating, humidifying, on the foul gas. Operation cost is low, covered area of equipment is small, operation and maintaining are simple, and the spiral self-preheating deodorization furnace can provide heat for other systems.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a spiral preheating type deodorization furnace and a waste gas deodorization process using the same. Background technique [0002] A large amount of poisonous, harmful, irritating, and foul-smelling gases will be produced in industries such as garbage disposal, sludge disposal, chemical industry, and coating, which will affect the environment and cause pollution. Therefore, it is necessary to use an incinerator to treat these gases and then discharge them to meet environmental protection requirements. However, the traditional incinerator directly incinerates the gas, which not only consumes high heat energy during the incineration process, but also has a high temperature of the exhaust gas, which results in a large loss of heat. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spiral self-preheating deodorization furn...
