Lime digester; It has a wide range of applications, mainly used in power plant desulfurization, metallurgy, soda ash manufacturing, biopharmaceuticals, alumina, chemical industry, water treatment, titanium dioxide, sugar production, ironmaking and other industries.
The main features of the quicklime digester are:
1. This device has its own independent and reasonable dust removal system, and is characterized by its compact structure
2. This device adopts double helix digestion, which has good digestion effect, uniform feeding, no spraying or blockage, and adopts a dual axis stirring form. It has multiple functions and effects such as stirring, crushing lumps, and self-cleaning. Its blades and mixing method ensure even mixing and sufficient reaction between quicklime and water; It has a crushing effect on the agglomerates generated during the reaction process.
3. This equipment is equipped with exhaust ports for steam and dust, which can be discharged to the dust removal pipeline through connecting pipes. It can effectively handle the dust, steam, and gas generated during the digestion process of quicklime. After use, it can achieve the reuse of waste dust and quicklime, and the on-site environment is free of dust pollution. This enables the quicklime digester to reasonably add the required water volume, achieving the effect of full digestion of quicklime.
4. A set of spiral feeding thrusters is designed at the feed inlet of the digester to prevent the backflow of steam and dust generated during the digestion process. The formed steam and dust are concentrated at the dust outlet and enter the dust removal equipment, reducing corrosion and damage to surrounding equipment and providing an excellent working environment. At the same time, it also improves the utilization rate of quicklime. This equipment adopts a covered water addition device, with uniform water addition and lime digestion.
5. The dual axis blades are made of high manganese material, and the heat-treated alloy material has the function of self-cleaning and bonding materials; Avoiding problems such as poor discharge, blade wear, and even shaft breakage caused by bonding lime, and extending the service life of the equipment.
6. The XH type dual axis quicklime digester can be improved in terms of relevant dimensions according to enterprise requirements, and automatic matching can also be added according to enterprise requirements.
7. The blades of the spiral shaft of this device are made of embedded hard alloy, which has the advantage of a long service life of one year.
The quicklime digester mainly adopts the method of lime digestion by using rotary motion instead of stirring. There is a sieve hole at the rear of the inner cylinder of the ash crusher, and the lime blocks are digested in contact with water in the inner cylinder. The lime milk flows out from the lower discharge outlet in the direction of the feeding port through the sieve hole. The undigested over burned and quickburned lime is discharged from the outer cylinder through the slag removal device at the tail of the outer cylinder. The structure and device of the ash machine are reasonable, easy to operate, and have high production capacity and low labor intensity. It is suitable for any quality of lime.
The quicklime digester is also known as a quicklime digestion machine, ash making machine, lime blending machine, etc. This machine is mainly composed of an outer cylinder, an inner cylinder, a support device, and a transmission device. The tail is equipped with a slag removal device. This machine is a device that digests quicklime (calcium oxide) into lime milk.
The working principle of the digester: In response to the existing problems, we have developed an environmentally friendly quicklime digester. The process is as follows: quicklime enters the environmentally friendly quicklime digester from the feed inlet and is digested with water in a double helix manner. At this time, a large amount of steam with dust is generated by using a fan to generate negative pressure in the water tank, and then the steam containing dust from outside is sucked into the water tank through the induced draft pipe, so that the steam containing dust is mixed with water in the dust removal water box through the dust removal sieve tube. In this way, dust settles when it meets water, while steam becomes water when it meets water. The generated sediment is mixed with external water in the water tank and then pumped away by a water pump before being added to the quicklime digester. This achieves the process of dust removal and wastewater recycling after dust removal. This solves the problems of low utilization rate of wet dust removal and secondary water pollution. The steam containing dust enters the water tank through multiple dust removal screens, each with multiple small holes drilled on it, so that the steam actually enters the water through the small holes. In this way, the water splashes generated by blowing water through each small hole will not carry away any dust, thus achieving the dust removal effect.
