High-low groove type oil-stain floating collection system

Abstract

The invention discloses a high-low groove type oil-stain floating collection system. The high-low groove type oil-stain floating collection system mainly comprises a high-groove structure and a low-groove structure, wherein the high-groove structure comprises a high-groove base, limiting vertical columns and an oil-collecting guide pipe; the limiting vertical columns are arranged in an inner cavity of the high-groove base; flexible springs are arranged at the upper parts of the limiting vertical columns; the lower ends of the flexible springs are fixedly connected with the limiting vertical columns; the upper ends of the flexible springs move up and down along the limiting vertical columns; a floating oil-collecting port is arranged in the upper part of the oil-collecting guide pipe and isconnected with the flexible springs; an outlet of the oil-collecting guide pipe is communicated with the low-groove structure; the low-groove structure comprises a low-groove base, a low-groove oil-collecting container, a floater liquid-level meter and a water discharging pipe. The high-low groove type oil-stain floating collection system disclosed by the invention has the beneficial effects thatby adoption of the high-low groove design, initial oil-water separation and floating collection are carried out in a high groove, and secondary oil-water separation is adopted in a low groove, so that the problem that the oil stains carry a large amount of water during oil-water separation in the existing collection equipment and method is solved.

Description

technical field [0001] The invention relates to oil pollution collection and treatment technology, in particular to a floating collection method for oil pollution in high and low tanks. Background technique [0002] At present, there are mainly two methods for oil-water separation, one is physical separation, and the other is chemical separation. These two methods have their own advantages and disadvantages. In addition, the oil generated by the car washing tank at the construction site cannot be collected and separated at any time, and can only be accumulated in the primary sedimentation tank; the conventional primary sedimentation tank uses a fixed overflow port, and when the liquid level drops, the oil layer cannot overflow, and it rains in rainy days Due to the low terrain of the sedimentation tank of the car wash tank, the rainwater is easy to collect and flow into the sedimentation tank in a short time, causing the oily liquid level of the sedimentation tank to rise to...

Problems solved by technology

In addition, the oil generated by the car washing tank at the construction site cannot be collected and separated at any time, and can only be accumulated in the primary sedimentation tank; the conventional primary sedimentation tank uses a fixed overflow port, and when the liquid level drops, the oil layer cannot overflow, and it rains in rainy days Due to the low terrain of the sedimentation tank of the car wash tank, the rainwater is easy to collect and flow into the sedimentation tank in a short time, causing the oily liquid level of the sedimentation tank to rise too fast, and the oil has no time to flow to the collection tank through the fixed overflow port, and it rises from the pool mouth and pollutes the ground environment. The sedimentation tank is often manually adjusted to replenish water, and the collection tank needs to be inspected and pumped every day; moreover, the volume of the sedimentation tank is large, the auxiliary separation device is complex, consumes a lot of energy, is inconvenient to use, and the investment cost is high; more importantly, the efficiency of oil-water separation low
