Problems solved by technology
[0003] At present, in the sludge treatment process, it is necessary to dry the sludge to separate the water in the sludge. In the prior art, most of the sludge is dried by heat treatment, and in the heat treatment process, due to the sludge There are residues mixed in, and the residues may cause danger due to flammability caused by excessive temperature. At the same time, after the residues are ignited, a large amount of harmful gases are produced, which pollutes the air.

The invention discloses sludge low-temperature drying equipment with a dehumidification function, and belongs to the technical field of sludge treatment. The sludge low-temperature drying equipment can achieve the effect that when convex thorns stir sludge filled in a sludge containing box, water in the sludge is adsorbed to the surface of a water-absorbing expansion balloon through water-absorbing tips, so that the sludge is dried; a sealing baffle plate applies pressure to an extension spring under the centrifugal action during stirring to open a flowing pipeline, and a water guide fiber guides a part of water on the surface of the water-absorbing expansion balloon into a storage balloon to chemically react with barium hydroxide octahydrate and ammonium chloride to achieve a refrigeration effect, so that cold air spreads to the surfaces of the convex thorns to condense a layer of frost, and the convex thorns are not easily damaged due to stone contained in sludge in the sludge stirring process; and meanwhile, an exhaust fan is used for exhausting air, water in the water-absorbing expansion balloon is air-dried, cold air enters a cooling pipe, the surface of the cooling pipe has a certain low temperature, and heat generated after the motor continuously works is cooled and dissipated.
Description
technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a low-temperature sludge drying equipment with dehumidification function. Background technique [0002] Sludge treatment is the process of reducing, stabilizing and harmlessly treating sludge. The higher the degree of sewage treatment, the more sludge residues will be generated to be treated, unless land treatment or sewage ponds are used Otherwise, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal have become the most complicated and costly part of the sewage treatment system. [0003] At present, in the sludge treatment process, it is necessary to dry the sludge to separate the water in the sludge. In the prior art, most of the sludge is dried by heat treatment, and in the heat treatment process, due to the sludge There are residues mixed in, and the residues may cause d...
