The reasons for the large amount of dust generated at the initial stages of the cottonseed oil production process and ways to reduce it are considered, which can pollute production premises and atmospheric air, worsen the working conditions of workers and employees, and cause them to contract an occupational disease.
KEYWORDS
Cotton seeds, airborne dust, cyclone, dynamic analysis, dust particles, conical cyclone, mineral fractions, air
circulation speed.
While great research is being carried out around the world to maintain an ecologically clean environment, the dusty air coming out of oil refineries in our republic also causes some damage to the ecology of the environment.
To solve this problem, it is necessary to select cleaning methods taking into account the composition of the dust when cleaning dust-laden air entering vacuum cleaners. A large amount of dust is released at all stages of primary processing of cotton seeds.
This dust pollutes the air of industrial premises and the atmosphere, worsens the working conditions of workers and employees, and can cause occupational diseases in them. Cyclone separators are widely used at the initial stages of the process of obtaining oil from cotton seeds at all oil mills and oil processing plants in our republic.
The oil and fat industry organizes processes for receiving, storing, preparing for processing and drying cotton seeds. When setting up an environmentally friendly oil production plant, it is important to capture the resulting dust.
One of the important tasks is to conduct targeted scientific research in areas such as the development of effective dust removal technologies. Models of cyclone separators have been in use for over a century without modification, but in reality, oil mill cyclones are designed to separate solids from process gas streams.
The main focus is on finding new ways to improve technological parameters. Recent studies have also commented on the evaluation of geometric effects in improving equipment performance. A conventional cyclone mainly consists of a cylinder equipped with a tangential inlet, a dust chamber and a vertical outlet pipe in a conical cleaning vessel, commonly known as conical cyclones.

The main indicator characterizing the effectiveness of any device for cleaning dust from dispersed compounds is the cleaning coefficient %.
According to studies of the physical and mechanical properties of dust and its composition, there are a number of difficulties in cleaning dust generated in the processes of cleaning cotton seeds from impurities, depilation, scalding, separating and separating the core from the husk, and they cannot be cleaned using any equipment for cleaning from dust.
Therefore, changing the design of currently used dust collectors is one of the most effective ways to capture dust generated in the oil and fat industry and effectively clean it. In addition, the use of chemical methods for cleaning such dust can also give the expected effective result.
Therefore, it is advisable to use solutions with surfactants to capture dust. Due to the high viscosity of such solutions, dust will adhere better than ordinary water. To do this, it will be necessary to analyze the scientific research conducted.
