Embodiment

[0031] A sludge dehydrator, see figure 1 and figure 2 , including a sludge chamber 1, a pulse power drive source 10, and an energy converter. The energy converter includes a casing 9 and a high-voltage electrode 5 and a ground electrode 6 that are oppositely arranged in the casing 9. A metal The wire 7, the high voltage electrode 5 are supported on the casing 9 through the high voltage insulator 8, the ground electrode 6 is connected to the casing 9 through the ground electrode support seat, the casing 9 is located at the gap between the high voltage electrode 5 and the ground electrode 6, and the gap is used as a shock wave output window and passed through The holster 4 is sealed, and the holster 4 is filled with pure water to form a water bag; the lower end and the upper end of the shell 9 protrude from the sludge chamber 1 respectively. The upper end of the sludge chamber 1 is provided with a wire storage tray 11. The upper end of the metal wire 7 passes through the groun...

Abstract

The invention provides a sludge dewatering method. Electric energy is converted into shock waves to act on the deep part of the sludge through electric explosion of metal wires, so that deep dewatering of the sludge is realized, and the problem that it is difficult for the existing sludge dewatering equipment to perform deep dewatering on the sludge is solved. The invention provides a sewage dewaterer. Shock waves are generated through electric explosion of the metal wires, the energy conversion efficiency is very high, the shock waves can act on tiny particles and capillary tubes in sludge, so that deep dewatering of the sludge can be achieved. The structure is simple, the implementation is convenient, continuous discharge can be implemented by supplementing metal wires, shock waves are enabled to continuously act on the deep position of the sludge, the dewatering effect is good, and the sludge dewatering rate can be increased by 10% or above.

Description

technical field [0001] The invention belongs to the technical field of sludge dewatering, and relates to a sludge dewatering method and a sludge dehydrator. Background technique [0002] Sludge is a solid-liquid mixture formed by living cells of bacteria and fungi and the gelatinous groups formed by them and water. Sludge, especially primary sludge, contains a large number of pathogenic bacteria, parasite eggs and viruses, which can easily cause large-scale spread of infectious diseases, and it is easy to corrupt and produce stench; at the same time, sludge is also a kind of resource, which contains a lot of heat , its calorific value is between 10000~1100kJ / kg (dry mud), which is higher than that of coal and coke; in addition, the sludge is also rich in nitrogen, phosphorus and potassium, which is an organic fertilizer with high fertilizer efficiency. Processing is important. [0003] There are roughly four combinations of water in sludge: (1) Interstitial water surrounde...
