The main raw and auxiliary materials and energy consumption of this 1 t/h cat litter production line in Saudi Arabia project are shown in the table below:

• Pea fiber: Pea fiber is made by separating the protein, starch and fiber from peas and extracting the fiber. The separated fiber has strong water absorption, and the high purity pea fiber does not contain protein.
• Corn starch: Corn starch is also called corn starch. The common name is Liugufen. It is a white and slightly yellowish powder, which is produced by soaking corn and then crushing, sieving, settling, drying and grinding. Ordinary products contain small amounts of fat, protein, etc. It has strong hygroscopicity, up to 30% or more.
• Guar gum: Guar gum is a highly purified natural polysaccharide extracted from guar beans. Due to its unique molecular structure and naturalness, guar gum has quickly become a new environmentally friendly additive with superior performance. Guar gum is a macromolecular natural hydrophilic colloid, a natural galactomannan, one of the quality improvers, and a natural thickener.
• Oil powder: Oil powder is the abbreviation of emulsified balanced oil powder. It is a feed additive. Its main ingredients are: emulsified fat powder, puffed corn meal, modified starch, protein, VE. It adopts triglyceride enzyme digestion, exchange and recombination. And emulsification technology, livestock and poultry are easier to absorb, and are more effective than other conventional oils and fat powders.

Brief description of process flow:

The purchased pea fiber, corn starch, etc. are weighed and proportioned according to the product ratio, and are manually fed into the sealed warehouse. The materials are sealed and conveyed to the sealed mixer through the stainless steel auger. The mixer uses the automatic water supply device to fill the water and mix it evenly. Long conveyed to the pellet machine.

The mixed material enters the cat litter pellet machine, and the pellets are pressed through a ring mold (normal temperature) and initially formed. The formed pellets are transported to a natural gas drying box through a closed conveyor, and the formed particles are dried at about 65°C (heated by natural gas).

After the cat litter pellets are dried and cooled, and the finished cat litter passes the inspection, it enters the automatic packaging machine, is vacuum packed and put into storage for sale.

The waste gas generated during the production process of the 1 t/h cat litter production line in Saudi Arabia project is mainly dust (feeding, packaging dust), natural gas combustion waste gas and drying waste gas.

Most of the raw materials used in the production process of the project are powders. Generally, dust is easily generated during the feeding, mixing, transportation, packaging and other processes.

However, the mixing process of the project is filled with water and is fully sealed. The transportation uses a sealed dragon, which basically does not generate dust. Therefore, this project Dust is mainly generated during the feeding, unloading and packaging processes.

During the feeding process of the 1 t/h cat litter production line in Saudi Arabia project, the suction fan on the side of the hopper is turned on throughout the entire process to form a slight negative pressure in the hopper, which can effectively prevent the material dust from escaping;

During the unloading and packaging process, the product is already granular, but there will still be some debris to generate dust. Limited, the amount of dust generated in the feeding and packaging section is calculated based on 2kg/t of raw materials. The actual amount of raw materials added to the project is 2954.05t/a, so the amount of dust generated is 5.908t/a (2.462kg/h).

[Pollution control measures]

The dust generated by the 1 t/h cat litter production line in Saudi Arabia project is collected and treated with a bag dust collector and then discharged through a 15m high exhaust pipe (1#) at high altitude.

The drying heat source of the project uses natural gas as energy, which is a clean energy. The consumption of natural gas is about 5000m3/a. Every 10,000m3 of natural gas burned produces 107753m3 of pollutant industrial waste gas, SO20.02Skg (S=200), and NOx15.87kg. The natural gas combustion exhaust gas is collected and discharged through a 15m high exhaust pipe (2#) at high altitude.

The raw materials of the project will contain a certain amount of moisture due to moisture. Fresh water also needs to be added during the material mixing process. The annual fresh water requirement is about 100t/a.

However, the project products have certain requirements for moisture content, so the granulated products need to be processed In the drying process, the drying temperature is set at about 65°C. The moisture contained in each material will evaporate to form water vapor. The hot steam rises to the reserved pipe of the dryer and is discharged at high altitude through the 15m high exhaust tube (2#).

[Pollution control measures]

Enterprises are required to strengthen the passage of machinery in the workshop and ensure air circulation in the workshop.

The noise source of the 1 t/h cat litter production line in Saudi Arabia project is the noise generated by the operation of various types of equipment.
