Dredging method and dredging agent for sewer blockage through rapid chemical reaction

Abstract

The invention relates to the field of dredging technology for sewer blockage and discloses a dredging method and a dredging agent for sewer blockage through a rapid chemical reaction. The dredging agent used in the dredging method comprises sodium hypochlorite used as an oxidizing agent for decomposition and dissolution of entanglement, sodium dodecyl benzene sulfonate capable of decomposing grease adhered on the inner wall of a water channel, caustic soda, an exothermic agent--aluminum powder and an auxiliary exothermic agent--sodium gluconate. Group A powder component and group B dredging agent component are composed, wherein the group A powder component comprises 20% of aluminum powder and 5% of sodium gluconate, and the group B dredging agent component comprises 20% of sodium hypochlorite, 40% of caustic soda and 15% of sodium dodecyl benzene sulfonate. In usage of the dredging agent provided by the invention, the powder of the group A powder component is poured into a blocked sewer, then the group B dredging agent component is poured, and rapid stirring is carried out so as to decompose blocking substances in the sewer. The dredging agent provided by the invention can rapidly react to dissolve and decompose resins, hairs and meal residues in a pipeline, thereby allowing the blocked sewer to be unobstructed; the cost of the dredging agent is 5 to 10 times less than cost of a dredging machine; and the dredging agent is safe and reliable to use.

Description

technical field [0001] The invention relates to the technical field of dredging waterway blockages, in particular to a dredging method and dredging agent for rapid chemical reaction of sewer blockages. Background technique [0002] At present, the traditional sewer blockage unclog device (machine or manual) is used in daily life. Most of this unclog device uses a spiral steel wire to screw in and out at the sewer blockage. It must be completed by electricity or manually. It takes a lot of effort when working, and the working time is long, especially the fees charged to users are high. Every year, a large number of users use dredging machines or manual labor, so that the cost of consumables and labor is not low, which does not meet the production requirements of low energy consumption. There are two reasons why the sewer is often blocked. (1) It is the blockage caused by the insoluble grease or the solidified grease that becomes resinous after oxidation. The sticky resinous g...
