Abstract

The invention relates to an unpowered sludge dehydration device, comprising a fluid bath arranged on the upper surface of the tank bottom of a dehydration tank; wherein the upper surface of the tank bottom of the dehydration tank is obliquely arranged with the horizontal plane, a dehydration woven bag is arranged on the upper surface of the tank body of the dehydration tank, the length direction of the dehydration woven bag is the same as the length direction of the dehydration tank, an outlet end of the dehydration woven bag stretches out of the dehydration tank and the inlet height of the dehydration woven bag is higher than the outlet height of the dehydration woven bag; the inlet end of the dehydration woven bag is arranged above a high end of the dehydration tank, a tying belt is arranged at the outlet of the dehydration woven bag and a water storage tank and a slag storage tank are arranged at the outside of a low end of the dehydration tank; wherein the distance between the water storage tank and the low end of the dehydration tank is smaller than the distance between the slag storage tank and the low end of the dehydration tank. After being installed, the unpowered sludge dehydration device can automatically carry out dehydration without external power, features good dehydration effect, simple structure, small volume, low manufacturing cost and conservation of massive funds and energy.

Description

technical field

[0001] The invention relates to an environmental protection device, in particular to an unpowered sludge dewatering device. Background technique

[0002] Sewage treatment will produce sludge, and most of the sludge is activated sludge with a particularly high water content, most of which are organic matter, and also contain toxic substances, heavy metals, phosphorus, ammonia, nitrogen and other substances. If the sludge is not dehydrated, it will be It brings troubles to the comprehensive treatment of sludge transportation, packaging, deep processing, power generation, incineration, etc. Conventional (50%) sludge treatment needs to obtain relatively dry sludge, which must be buried, filtered, centrifugally separated, and vacuum squeezed Separation, heating and separation methods consume a lot of power energy and heat energy. At the same time, all sludge dewatering equipment is bulky, expensive, requires high mechanical maintenance costs, and requires a lot of...
