Novel sludge treatment device

Abstract

The invention discloses a novel sludge treatment device which comprises a reaction body with a steam inlet and a sludge outlet. The reaction body is connected with a rotating shaft of a rotating motor, the rotating motor is positioned on a supporting platform, a compressed gas inlet is formed in the reaction body, a plurality of uniformly arranged cutting blades are arrange don the inner wall of the reaction body, the sludge outlet is connected with a high-constant-temperature box through a sludge pump, and a mud outlet is formed in the bottom of the high-constant-temperature box. According to the device, overall dewatering effect of sludge is improved and balanced, the dewatering rate of the sludge is greatly increased, the probability of secondary pollution of the sludge is reduced, volume and weight reduction, stabilization and harmlessness treatment of the sludge is achieved, and the device further solves the problem of spread of infectious diseases easily caused by harmful germs, parasitic ova and diseases, so that more environment-friendly and safer discharging of the sludge is achieved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a novel sludge treatment equipment. Background technique [0002] The water content of domestic sludge is generally very high. The existing sewage treatment process uses hot steam to heat the sludge in the reaction body to achieve the effect of sludge dehydration. However, due to the unstable pressure in the reaction body, the hot steam The distribution in the reaction body is not very uniform, and most of the hot steam gathers in the upper part of the reaction body, which makes the dehydration effect of the sludge in the lower part of the reaction body not very ideal. The mud cannot be well exposed to the hot steam, which makes the whole dehydration effect of the sludge uneven. The moisture content of the dewatered sludge in the existing technology is generally 75% to 85%, which is colloidal and sticky, which is easy to cause secondary dehydration. secondary pollution, a...

[0002] The water content of domestic sludge is generally very high. The existing sewage treatment process uses hot steam to heat the sludge in the reaction body to achieve the effect of sludge dehydration. However, due to the unstable pressure in the reaction body, the hot steam The distribution in the reaction body is not very uniform, and most of the hot steam gathers in the upper part of the reaction body, which makes the dehydration effect of the sludge in the lower part of the reaction body not very ideal. The mud cannot be well exposed to the hot steam, which makes the whole dehydration effect of the sludge uneven. The moisture content of the dewatered sludge in the existing technology is generally 75% to 85%, which is colloidal and sticky, which is easy to cause secondary dehydration. secondary pollution, and may also cause secondary pollution during transportation, which can no longer meet the requirements of environmental protection, and subsequent sludge treatment methods such as composting, incineration, landfill, etc. require the moisture content to be below 60% to further reduce the sludge moisture content The efficiency is an important basis for sludge volume reduction, stabilization and harmless disposal. In addition, due to the high content of organic matter in sludge, it is easily corrupted and produces stench, so the stacking and discharge of sludge will pollute the environment. A large number of germs, parasite eggs and viruses contained in sludge can easily cause the spread of infectious diseases
