Micro-positive pressure dust isolation system

Abstract

The invention discloses a micro-positive pressure dust isolation system. An air storage tank, an air compressor, an air duct and a pressure regulating valve are mounted in an isolation tank casing onan equipment platform; air pressure in the air storage tank is adjusted to be a micro-positive pressure state, and then air enters a driving cab; air filters and back flushing devices are mounted on the side walls of the two sides of the isolation tank casing; an electric control cabinet is mounted at the top of an isolation tank; an air inlet is formed in the upper part of the top of the drivingcab; an air outlet is formed in the lower part of the top of the driving cab; pressure of clean air subjected to dust removal through filtering of the air filters is adjusted to be micro-positive pressure, and then the clean air is connected with and conveyed to the interior of the driving cab, so that air pressure in the driving cab always keeps a micro-positive pressure state slightly higher than that of the outside. The system can isolate dust outside the driving cab, prevent dust from entering the equipment driving cab, keep environmental health of air in the driving cab, and reduce the equipment maintenance workload, and is convenient in mounting operation; the system device can be further applied to all other similar dynamic and static equipment requiring dust isolation and places, such as site work and rest rooms, surrounded by dust.

Description

technical field [0001] The invention relates to a micro positive pressure dust isolation system. Background technique [0002] The raw material of high-density calcined petroleum coke in the carbon manufacturing industry is green coke, which is processed by residual oil after delayed coking. Carbon form, the granular piled raw materials contain a certain proportion of powdered coke, which will cause dust pollution during the process of processing, manufacturing, production transfer, and material dumping; in the prior art, a fully enclosed steel structure greenhouse is used to cover the raw material stacking and taking place In the process of production and processing, the dust is limited to fluttering in the greenhouse when it is stacked and taken, and will not pollute the external environment. However, because the quality of the dust is relatively light, and the equipment is still working continuously, the dust floating in the air will be suspended in the air for a long tim...

[0002] The raw material of high-density calcined petroleum coke in the carbon manufacturing industry is green coke, which is processed by residual oil after delayed coking. Carbon form, the granular piled raw materials contain a certain proportion of powdered coke, which will cause dust pollution during the process of processing, manufacturing, production transfer, and material dumping; in the prior art, a fully enclosed steel structure greenhouse is used to cover the raw material stacking and taking place In the process of production and processing, the dust is limited to fluttering in the greenhouse when it is stacked and taken, and will not pollute the external environment. However, because the quality of the dust is relatively light, and the equipment is still working continuously, the dust floating in the air will be suspended in the air for a long time and will not pollute the external environment. The pervasive drilling into the cab of the stacking and reclaiming equipment in the steel structure greenhouse has long-term violations of the health of the operators in the cab, and it will also drill into the electrical appliances and instrument panels in the cab to cause equipment failures, which poses greater occupational hazards and Hidden dangers in production safety; the equipment and operators in the greenhouse are in a heavily dust-polluted environment, and there are serious hidden dangers in production safety and occupational health and safety
