The paper discusses the physical properties of the silica clay used as building material and mineral. During crushing, pouring, packing and other processes the dust which enters the storage bunkers of dust removal systems, is formed; it is emitted from the dust collecting devices into the atmosphere, and a part of the dust enters the working area. The paper compares the elemental composition of the silica clay before the crushing operation; the dust collected in bunkers of dust removal systems; in the air emissions; the dust after using the dust collectors and working area air dust. The study was conducted using a Versa 3D Dual Beam scanning electron microscope. The dust characteristics’ comparative studies were carried out in three intake zones for three types of dust collectors used in dust removal systems: fabric filters, cyclones and swirling approach flows (SAF). The homogeneity hypothesis was tested using the Kolmogorov-Smirnov criterion. Based on the measurement results, it was concluded that the dust from the dust bunkers for all the dust collector options has a close elemental composition and can be returned to the additives’ production process. It is shown that the dust entering the working area air and in emissions into the atmosphere are close in their characteristics. The results of measuring the random distribution functions of the elemental composition and molecular weight are obtained, which allow calculating particle weight and other characteristics with 95% certainty, as well as evaluating the aerodynamic characteristics of dust particles, etc.
Complex influence of the ground of waste of the oil refinery including three sections of a pond store, a pond evaporator, a pond - the store of synthetic fatty acids, a dump of solid industrial wastes, the card of viscous waste of production of additives on the environment is investigated. It is revealed that the main pollutant are oil products (oil hydrocarbons), the steady trend of their accumulation in the environment is noted.
It is established that extent of utilization of the petrowaste which is valuable secondary raw materials is small that leads to their accumulation on the grounds and sludge collectors which are sources of environmental pollution. Extent of recycling of production of additives is especially low that is explained by their complex structure causing the low productivity and high cost of technological process of their processing.
The scheme of the organization of monitoring of a condition of the environment around placement of the ground of waste including control of a condition of the atmosphere, underground waters and soils is offered.
Reduction of environmental pollution by waste of oil processing due to their greatest possible secondary use and consequently, and economy of scarce and expensive natural raw materials, it is possible only in the presence at the enterprise of the comprehensive program of waste management.
The theoretical and pilot researches directed to decrease in negative impact of the ground of waste of oil refineries on the environment are conducted, the method of liquidation of the map of viscous production wastes of additives with use of production wastes of the additive DF-11 (KEK) is developed.
In this research was studied gathering efficiency and breakthrough of flask dust particles in industrial plants. The experiments were carried out on devices with counter swirling flows with various modifications and diameters of 150, 400, 600, and 800 mm. Analyzed and graphically presented the dependences of particle breakthrough on tghe devices size. The breakthrough effect in small inertial VZP devices was investigated, also the construction of VZP device was designed and experimentaly tested under operating conditions in terms of productivity and energy losses close to standard devices, but excluding the breakthrough effect of larger particles. Recommendations are given for the device usage on counter swirling flows with the best characteristics for capturing flask dust particles.
The work considers the breakthrough effect of large particles in a small diameter device on counter-swirling flows. The dependences of particle breakthrough on different diameter devices were built. An experiment was carried out on a device of 100, 200, 300 and 400 mm with top paddle strikers installed at the axial outlet. A comparative analysis is made with the calculated and experimental data of the researchers in this area. The results of devices with small diameter are obtained and presented in the visual graphs and conclusions.
