Unpowered sludge dewatering device

Abstract

The invention relates to an unpowered sludge dewatering device, which comprises a liquid flow tank set on the upper surface of the bottom of the dewatering tank platform, the upper surface of the tank bottom of the dewatering tank platform is inclined to the horizontal plane, and the upper surface of the dewatering tank platform A dehydration woven bag is placed on the upper surface of the bottom of the tank. The length direction of the dehydration woven bag is consistent with the length direction of the dehydration tank table. The height of the outlet, the inlet end of the dehydration woven bag is set above the high end of the dehydration tank table, the tie belt body is set at the outlet of the dehydration woven bag, and the water storage tank and the slag storage tank are arranged outside the low end of the dehydration tank table. The distance between the water tank and the lower end of the dewatering tank table is smaller than the distance between the slag storage tank and the lower end of the dewatering tank table. After the invention is installed and used, it can automatically dehydrate without consuming external power, has good dehydration effect, simple structure, small volume, low cost and can save a lot of 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...

Problems solved by technology

[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 separation and other methods need to 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 labor to operate.

Calculated according to the moisture content of 80%, my country will produce 30 million tons of sludge from 2009 to 2010. If the above traditional methods are used to deal with it, a lot of money and energy will be wasted.
