Abstract

The invention discloses a sludge low-temperature drying mechanism for sludge treatment. The sludge low-temperature drying mechanism comprises a closed sludge drying chamber; the closed sludge drying chamber is equipped with a sludge inlet, multiple layers of end-to-end connected conveying net belts and a sludge outlet from top to bottom; two fans, including a first fan and a second fan, are arranged at an interval on the lower side of the bottom layer of conveying net belt; an air filtering device is arranged on the upper side of the top layer of conveying net belt; a condenser is arranged onthe left side of the air filtering device; an output end of the condenser is connected with an input end of a heat exchanger; the output end of the heat exchanger is connected with the input end of aliquid storage tank; the output end of the liquid storage tank is connected with a first input end of a gas-liquid separator; a bulk collecting device is arranged on the bottom in the closed sludge drying chamber; the bulk collecting device comprises a sludge collecting mechanism and a sludge conveying mechanism. The sludge low-temperature drying mechanism for sludge treatment is capable of solving the problems that the drying effect of the sludge low-temperature drying device is uneven, the energy utilization efficiency is low and the blanking materials are difficult to be collected.

Description

technical field [0001] The invention relates to a sludge treatment mechanism, in particular to a sludge low-temperature drying mechanism used in sludge treatment. Background technique [0002] With the large-scale construction and operation of sewage treatment plants in my country, the sludge output has also increased significantly, and the threat to environmental pollution has become increasingly serious. However, most of the dehydrated sludge has a moisture content higher than 80% and contains a large amount of toxic and harmful substances. It is unstable in nature and difficult to utilize as resources. Therefore, proper drying treatment is extremely necessary before final disposal such as composting or incineration. The low-temperature heat pump drying technology in the drying technology has the advantages of small footprint, drying The unique advantages of high efficiency and little pollution to the environment. [0003] The low-temperature drying equipment adopts the pri...
