Problems solved by technology

[0003] However, it is unavoidable that the currently used sludge drying and incineration systems often have certain defects. For example, the utilization rate of waste heat is not high, the cost of wastewater treatment is high, and the utilization rate of incineration is low. Such defects will often be greatly improved. The cost of sludge drying and incineration, and the waste cannot be effectively used for recycling

Abstract

The invention discloses a sludge drying and incineration system. The system comprises a sludge tank, a drying system, an incineration system, a water regeneration system and a heat recovery system, wherein the drying system comprises an evaporation tank, a centrifugal dryer and a heat source dryer; the incineration system comprises a sludge intermediate bin, an incinerator and a screening slag extractor; the heat recovery system comprises a heat conduction oil storage tank, a heat exchanger, a condenser and a heat conduction oil circulation pipeline. The water regeneration system sequentiallycomprises a filter tank, a sedimentation tank, a ring filter, a purification tank and a water storage tank. The sludge drying and incineration device is used for drying and incinerating sludge; an intermediate product can be recycled; the drying process is carried out by a plurality of devices in sequence, the drying efficiency is high, and the effect is good; a heat source in the drying process utilizing the heat source is obtained by recycling waste heat so that the drying energy consumption and cost are greatly reduced; produced wastewater is regenerated through a water regeneration system,so that the water resource is saved; furnace slag is recycled and screened, recycling is facilitated, and in conclusion, the sludge drying and incineration system has the advantages of being capableof saving energy, environmentally friendly and capable of achieving waste utilization.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a sludge drying and incineration system. Background technique [0002] The sludge drying and incineration system is a complete set of treatment equipment for the harmless treatment of sludge. It is widely used in the field of sludge treatment because of its remarkable advantages such as fast treatment speed, small footprint, and no need for long-term storage. [0003] However, it is unavoidable that the currently used sludge drying and incineration systems often have certain defects. For example, the utilization rate of waste heat is not high, the cost of wastewater treatment is high, and the utilization rate of incineration is low. Such defects will often be greatly improved. The cost of sludge drying and incineration, and the waste cannot be effectively used for recycling. Contents of the invention [0004] Aiming at the above problems, the present inventi...
