Problems solved by technology

[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

Embodiment 1

[0013] Such as figure 1 As shown, the present invention provides a new type of sludge treatment equipment, including a reaction body 1 provided with a steam inlet 11 and a sludge discharge port 14, the reaction body 1 is connected to the rotating shaft 21 of the rotating motor 2, and the rotating The motor 2 is located on the support platform 3, the reaction body 1 is also provided with a compressed gas inlet 12, the inner wall of the reaction body 1 is provided with a number of uniformly arranged cutting pieces 4, and the sludge discharge port 14 passes through The sludge pump 5 is connected to a high temperature constant temperature box 6, the bottom of the high temperature constant temperature box 6 is provided with a mud outlet 61, the inner wall of the reaction body 1 is provided with a temperature sensor 7, and the support platform 3 is equipped with and The temperature sensor 7 matches the temperature receiving display 8, and the reaction body 1 is also provided with a ...

Embodiment 2

[0015] Such as figure 1 As shown, after the sludge to be dehydrated is located in the reaction body 1, hot water vapor and compressed gas are introduced through the steam inlet 11 and the compressed gas inlet 12 respectively, so that the hot water vapor can be evenly distributed in the reaction body 1, then start the rotating motor 2, and the rotating shaft 21 drives the reaction body 1 to start rotating. When the reaction body 1 is rotating, the cutting piece 4 can break up the blocky sludge, increasing the overall contact area between the sludge and hot water vapor , the dehydration efficiency is improved, and the dehydration effect is improved. When the dehydration is completed, the sludge discharge port 14 is opened, and the sludge pump 5 is started. The sludge in the reaction body 1 enters the high-temperature thermostat 6 through the sludge pump 5, and the high-temperature The temperature of the incubator 6 is set at 300° C., and the sludge is discharged through the slud...

Embodiment 3

[0017] Set the specified temperature range for sludge dehydration to 70~90°C. During the dehydration process, once the temperature of the reaction body 1 detected by the temperature sensor 7 exceeds 90°C, the cooling air inlet 13 is opened to flow into the reaction body 1. Pass in cooling air, stop passing in cooling air after the temperature drops to within the specified temperature range.

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.
