Detailed Description
The present invention will be described in detail with reference to the accompanying drawings. As shown in fig. 1, the catalytic furnace comprises a furnace body 1, wherein the furnace body 1 is a cuboid, a heating catalytic chamber 2 is arranged at the right end of the furnace body 1, an electric heating pipe 3 is arranged at the lower part in the heating catalytic chamber 2, and a catalytic bed 4 is arranged at the upper part. The middle part of the furnace body 1 is a preheating chamber 5, and the left side of the preheating chamber 5 is provided with a waste gas inlet pipe 8 and a clean gas outlet pipe 9.
Wherein, a preheating pipe 6 and a partition 7 are arranged in the preheating chamber 5.
Wherein, a bypass air valve 10 is arranged between the heating catalysis chamber 2 and the purified air outlet pipe 9.
The electric heating catalytic oxidation furnace has the following specific implementation modes:
the furnace body is mainly divided into a catalytic chamber and a preheating chamber, organic waste gas firstly enters the preheating chamber through a waste gas inlet pipe and passes through the outer part of the preheating pipe to exchange heat with high-temperature gas in the preheating pipe, so that the temperature of the organic waste gas is improved. In order to improve the heat exchange efficiency, a plurality of partition plates are arranged in the preheating chamber, so that the outer part of the tube is an S-shaped path, and the heat exchange time is prolonged.
After the organic waste gas is preheated to a certain temperature, the organic waste gas enters a catalytic chamber, the temperature is raised to about 400 ℃ under the heating action of an electric heating pipe to reach a catalytic process temperature, and at the moment, the organic waste gas enters a catalytic bed.
The catalytic bed is provided with a plurality of layers of ceramic honeycomb blocks plated with noble metal catalysts such as platinum, palladium and the like, and organic waste gas starts to be oxidized and decomposed under the catalytic action of the catalysts when passing through the pores of the honeycomb blocks to become harmless carbon dioxide and water, and then is discharged to the preheating chamber. The temperature of the purified gas is about 450 ℃, the purified gas enters the preheating pipe and exchanges heat with low-temperature organic waste gas newly entering the preheating pipe outside the preheating pipe, and the purified gas is discharged to the atmosphere through the purified gas outlet pipe after the temperature of the purified gas is reduced.
This electrical heating catalytic oxidation stove still has safety coefficient, and when the exhaust gas temperature behind the electrical heating was too high, can cause the harm to the catalyst, the bypass blast gate between catalysis room and the clean gas play tuber pipe was opened this moment, makes high temperature gas discharge fast to send into new trend and come rapid cooling, guaranteed the security of equipment, extension equipment life.
The device integrates the inlet and outlet pipelines, the preheating chamber and the catalysis chamber as much as possible, reduces the volume of the device and reduces the floor area of the device.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
