Application of sludge dewatering screen in sludge treatment

From the perspective of sludge treatment equipment supply, the equipment supply chain of sludge treatment can be refined and divided into tempering and wall breaking, sludge dewatering machine, conveying equipment, deodorizing equipment, digestion equipment, composting equipment, drying equipment, and incineration equipment according to demand. Among them, the technical content of dewatering machine, conveying equipment, and deodorizing equipment is relatively low, and tends to be general equipment; while the technical content of digestion equipment, composting equipment, drying equipment, and incineration equipment is relatively high, involving the company’s parameter setting for sludge treatment process, engineering experience, etc.; the highest technical barriers are still related technical equipment of tempering and wall breaking.

Harmlessness and stabilization are the basic requirements of various treatment technologies, and the method is incineration and subsequent treatment of fly ash; tempering and wall breaking are the key links to achieve breakthroughs in the requirements of reduction; in energy resource utilization, anaerobic digestion and coordinated incineration are the development direction.


The sludge treatment market is currently in its infancy, and the treatment scale of various companies in the industry is small and highly dispersed, basically at a disposal scale of less than 1,000 tons/day.

Working principle and parameters of industrial slurry pump

In order for the industrial slurry pump to fully play its role, we need to understand the working principle of the industrial slurry pump: https://www.lzzgmachine.com/products/supporting-equipment/slurry-pump.html Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy to leave the outer edge of the impeller at a high speed and enter the volute pump shell. In the volute pump case, the Fluid is slowed down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy. At last, it flows into the discharge pipe and is sent to the place where it is needed. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Above the liquid level of the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. LZZG slurry pump pe...

Sandblasting nozzle classification and use

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently. Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle , double Venturi sandblasting nozzle, angle sandblasting nozzle Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.

How to build a sand and gravel aggregate production line

 High-quality aggregates (coarse aggregates and fine aggregates, fine aggregates are sand): First, the shape of the particles should be good, and the senses should be good; second, the gradation should be reasonable. Especially for machine-made sand, high-quality machine-made sand products must not only meet the sand requirements of commercial concrete, but also meet the requirements of higher standards for ready-mixed mortar sand (ready-mixed mortar is an inevitable requirement in the future. On-site stirring will be phased out over several years). Reasonable continuous grading can meet the needs of high-quality concrete. Both are indispensable. The fifth condition for the success of the sand and gravel aggregate production line is that the aggregate product of the production line must meet the requirements of soil content. High-quality concrete has higher and higher requirements for soil content. The seemingly simple problem may be the reason for the failure of the project. Ther...
