A kind of processing method of dust-suppressing sludge solidifying agent

Abstract

The invention discloses a processing method of a dust-suppression sludge curing agent. The processing method includes: surfactants are added into water to prepare a surfactant aqueous solution, the surfactant aqueous solution is added into a curing agent and evenly stirred to obtain a humidified curing agent, the humidified curing agent is loaded onto transportation equipment for transportation, and the humidified curing agent is unloaded when being transported to a destination and used for construction, wherein the surfactants are anionic surfactants and / or nonionic surfactants; the mass percentage of the surfactants is 0.008-0.1%, and the balance is water; the adding amount of the surfactant aqueous solution is 5-11% of the weight of the curing agent. The method has the advantages that 1-3 kinds of surfactants are added into the water under the premise that the performance of the curing agent is unaffected, the problems of caking and heat generation caused by adding water into the curing agent are solved, and the problem of flying dust during the loading, transportation and stirring of the curing agent is solved; the curing agent is transported in bulk by using a common truck and covered by tarpaulin, material supply mobility is improved, influence on curing agent performance is low, and engineering technology production requirements are satisfied.

Description

technical field [0001] The invention relates to a processing method of a dust-suppressing sludge solidifying agent, which solves the dust raising problem in the construction of the sludge solidifying agent. Background technique [0002] It is difficult to avoid the dust problem during the loading and unloading of powdery sludge curing agent and construction mixing. Several common methods to solve this problem include using special facilities and preparing the curing agent into slurry. Bagging and tanking of powder curing agent can reduce part of the dust, but dust is still generated during unloading and mixing, especially in windy weather, resulting in a harsh construction environment. It is also necessary to set up a vertical storage tank for unloading of tank trucks, which reduces the mobility of materials and the radius of construction operations. Adding water to the curing agent to make a slurry can avoid dust during construction and mixing. However, special slurry supp...

Problems solved by technology

However, through laboratory and engineering tests, it is known that the amount of water added and whether it is uniform will cause two major problems, one is the problem of agglomeration and pilling, and the other is the problem of premature failure of the curing agent due to the large amount of heat of hydration

If a car of curing agent sprayed with water is transported to the construction site, these two problems exist at the same time, and the delay time is less than 2.5 hours
