Abstract

PURPOSE:To dehydrate efficiently sewer sludge, etc. by usng respectively separately a coarsely meshed filter cloth belt for the belt to be used in a gravity dehydration zone and a finely meshed filter cloth belt for the belt to be used in a compressive dehydration zone. CONSTITUTION:The sludge supplied into a trough 3 is successively gravitationally dehydrated and thickened by an upper filter cloth 2 and a lower filter cloth 2 in a gravity dehydration zone A. The sludge is then fed to a compressive dehydration zone B where the sludge sandwiched by the cloths 2 is guided zigzag by plural rolls 1' and is pressed by press rolls 5 and is thus compressively dehydrated. The filter cloth belts 2 meshed at >=14,000cc/sec-cm<2> on the basis of air permeability are used for said belts to be used in the zone A and the filter cloths meshed at 10,000-14,000cc/sec-cm<2> air permeability are used in the zone B.

らＩしていゐ。Ken) Next, between many parallel rolls, a pair of upper cylinders were freely runnable and rotated, and between these cylinders 1ζ←Sosakakigiku, the gravity of the sewage sludge before being supplied was applied to the hydraulic power. Belt presses are well known in which the water is squeezed, pressed into the rolls, and then dewatered using another pressing device. In order to use ICs like this, it is necessary to use an 11i scale machine, and the machine frame is also large in size, so the dehydration process as described in NFJ is carried out in the dehydration zone and pressure. I am well aware of belt presses that are divided into zones and configured separately.

In ζmetsu, 44 Luka dehydration zones/A and pressurized dehydration zones B are formed in the running section of a pair of furnace cloths 2.2/In addition, the arrangement is as follows: Yang Hui,
If gravity dehydration, which requires coarse mesh, is satisfied, the cake will leak during compression, and if fine-mesh furnace cloths 2, 2 are used to satisfy compression dehydration, gravity dehydration will be insufficient, and 1 c. Keihin ran away and iP'lli 2, 2
On the other hand, it protrudes and cannot be squeezed out, so this invention was developed by solving the above-mentioned problems. In the gravity dehydration zone A and the squeezed water zone B, the parent M tl: /Jth P Ri 2 ,

It was confirmed that a well-balanced amount of water and compressed dehydration can be achieved using one bar of water. In addition, when it comes to dirty soil construction, Piaz, 2 used for compressed dewatering requires a fire of 1000 to 3000 ca/L-, which is much lower than that of 10υQQ06/Dai-1. ≧ Of course, it is essential to do -C.
