Overview

The sale of new types of second-hand solid waste, waste residue, dewatering centrifuge, and alkaline residue poses a great threat to the ecological environment. In the production of pure alkali by ammonia alkali method, the treatment of alkali residue and white mud has always been a very difficult problem for many enterprises, which restricts the application of ammonia alkali process in the pure alkali industry. The amount of alkali residue produced is 30% to 35% of the production of pure alkali. Nowadays, with the increasing emphasis on environmental protection both domestically and internationally, alkali plants are constantly seeking the resource utilization of alkali residue, including environmental protection while saving the cost of alkali residue treatment,

Selling a new type of second-hand solid waste residue dewatering horizontal screw centrifuge

Alkali residue from alkali plants, commonly known as white mud, is a solid waste (waste residue) generated during the production of pure alkali by ammonia alkali method. Alkali residue poses a great threat to the ecological environment. In the production of pure alkali by ammonia alkali method, the treatment of alkali residue and white mud has always been a very difficult problem for many enterprises, which restricts the application of ammonia alkali process in the pure alkali industry. The amount of alkali residue produced is 30% to 35% of the production of pure alkali. Nowadays, with the increasing emphasis on environmental protection both domestically and internationally, alkali plants are constantly seeking the resource utilization of alkali residue, including environmental protection while saving the cost of alkali residue treatment. Otherwise, the development of enterprises and society will be an empty promise.

The separation equipment of solid control and the related processing equipment of the horizontal screw centrifuge can efficiently solve the problem of alkali residue or white mud dehydration in alkali plants. The Guanneng horizontal spiral centrifuge has become the core equipment for alkali residue wastewater treatment.

Compared with other alkali residue treatment equipment, Guanneng horizontal screw centrifuge has the following advantages:

The Guanneng alkali residue treatment centrifuge has a small footprint and is easy to install.
Through PLC program control, continuous work can be achieved and the operation is simple.
Compared to other devices, the Guanneng horizontal screw centrifuge produces a large amount of sludge and has lower energy consumption.
The low maintenance cost of Guanneng horizontal screw centrifuge greatly reduces the cost of alkali residue mechanical separator
Unlike the process requirements of the plate and frame filter press, the slurry processed by the Guanneng horizontal screw centrifuge does not require a sand separation process.
The sand content in conventional distillation waste liquid can be separated by a crown energy centrifuge without affecting the capacity of the device.
A standardized marketing service network can provide more timely services for ammonia alkali production enterprises in various regions.

2、 Working principle
The sludge to be treated is connected to the input end of the sludge feeding system through a pipeline. The long fiber impurities in it are cut and crushed by a sludge cutting machine, and then metered by a flow meter through a feed pump (single screw pump) and input into the sludge dewatering machine (horizontal screw centrifuge).
The flocculant (powder or liquid) is diluted and fully dissolved in the mixing tank according to the proportion, and then enters the storage tank. The mountain dosing pump controls the flow rate determined by the dehydration process requirements. After dilution with water at a concentration of 0.08-0.12%, it enters the dewatering machine and mixes with the sludge to be treated. The flocculant solidifies into a dense state. After the sludge is dehydrated by the dewatering host, the clarified sewage is discharged through the pipeline of the mountain clarification liquid, and the dehydrated sludge is discharged from the discharge outlet of the host and then transferred to the site or directly loaded onto the truck for external transportation by a flexible shaftless sludge conveyor (or sludge conveying pump). The continuous input of sludge to be treated, the continuous discharge and transportation of clarified liquid and dehydrated sludge is a fully automatic treatment process. The dosing, feeding, sludge transportation, and operation of the main unit of the grid device are all detected and controlled by a fully automatic PLC electro-hydraulic control box, making the device a fully automatic complete set of operating units.
