Problems solved by technology

However, the traditional incinerator directly incinerates the gas, which not only consumes a lot of heat energy during the incineration process, but also exhausts a high temperature exhaust gas, which results in a large loss of heat.

Embodiment 1

[0028] like Figure 1 to Figure 4 As shown, it is a spiral self-preheating deodorization furnace provided in Embodiment 1 of the present invention, which includes an inner cylinder 3 , an outer cylinder 4 , a spiral guide 2 , an insulation layer 7 , a fan 8 , and a gas analyzer 9 .

[0029] The outer cylinder 4 includes a preheating chamber 10 and a combustion chamber 11 . The bottom side of the outer cylinder 4 is provided with an exhaust gas inlet 1 . The exhaust gas inlet 1 communicates with the preheating chamber 10 . A gas inlet 12 is provided on the top side of the outer cylinder 4 . The gas inlet 12 communicates with the combustion chamber 11 . In this embodiment, the gas inlet 12 is tangent to the outer wall of the combustion chamber 11 .

[0030] The top of the inner cylinder 3 communicates with the combustion chamber 11 of the outer cylinder 4 . A waste gas outlet 6 communicates with the bottom of the inner cylinder 3 . In this embodiment, the outer cylinder 4 ...

Embodiment 2

[0042] This embodiment is roughly the same as Embodiment 1, except that the helical guide piece in this embodiment is set in a form of variable pitch (such as Figure 5 As shown), the pitch of the helical guide piece gradually decreases from bottom to top, so that the gas can be compressed step by step during the rising process, and the temperature of the exhaust gas to be treated can be increased.

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...
