Continuous type transmission sludge burning caking furnace

Abstract

The invention discloses a continuous type transmission sludge burning caking furnace which comprises a feeding device, a transmission wire belt, a furnace body system, a sideward discharging connecting wire belt and a wire belt naturally extending ditch. The feeding device comprises a support, a feeding machine and a feeding guide roller. The furnace body system comprises a preheating chamber, a heating chamber and a steam chamber. A preheating roller and a sideward discharging connecting wire belt driving roller are arranged inside the preheating chamber. A burner nozzle and a heatproof carrier roller are arranged inside the heat chamber. A transmission roller, a tensioning roller and a carrier roller are arranged inside the steam chamber. A driving roller and a support roller are arranged inside the wire belt naturally extending ditch. The transmission wire belt twines the feeding machine, the feeding guide roller, the preheating roller, the transmission roller and the tensioning roller and penetrates the heating chamber in the middle. The sideward discharging connecting wire belt twines the sideward discharging connecting wire belt transmission roller, the heatproof carrier roller, the driving roller and the support roller and penetrates the heating chamber and the steam chamber in the middle. High temperature smoke produced after burning is transmitted to the preheating chamber so that wet sludge is heated and then dried, waste heat is used, energy is saved and burning effect is good.

Description

technical field [0001] The invention relates to the field of environmental purification treatment equipment, in particular to a continuous conveying sludge incineration and agglomeration furnace. Background technique [0002] In recent years, with the progress of society, the phenomenon of environmental pollution has become increasingly serious, and urban sludge is one of the most important environmental pollutants. Therefore, the sludge produced after urban sewage treatment has always been a national environmental protection problem. There are a large number of bacteria, germs, nitrogen, sulfur, chlorine, heavy metals and other pollutants in the sludge, which is not only difficult to treat, but also seriously affects the normal operation of the sewage treatment plant, and affects the environment of the body and the normal life of people. [0003] Today's sludge treatment generally involves direct incineration of sludge, in which a large amount of steam is generated when th...

There are a large number of bacteria, germs, nitrogen, sulfur, chlorine, heavy metals and other pollutants in the sludge, which is not only difficult to deal with, but also seriously affects the normal operation of the sewage treatment plant, but also affects the environment of the body and the normal life of people

[0003] Today's sludge treatment generally involves direct incineration of sludge, in which a large amount of steam is generated when the wet sludge is burned, and the heat contained in the steam can be recovered and utilized. However, these steams contain a large amount of harmful gases, which increases the difficulty of recovery ;In addition, in order to fully burn the sludge, the method commonly used at present is to dry the wet sludge through a sludge dryer, and then incinerate it at a high temperature in an incineration tower. Drying is usually heated and dried by steam. However, due to the relatively high investment in sludge treatment, the drying and incineration processes require heating and high temperature respectively, so this method will also increase energy costs

The flue gas mixture coming out of the incineration tower itself has a very high temperature. If this part of the flue gas mixture is allowed to dissipate its heat naturally instead of being used, it is also a waste of energy.

In addition, because the heat contained in the sludge varies greatly, the temperature of the flue gas produced by the existing incinerator is very unstable, which limits the further recycling of the flue gas
