Opposite shrinkage type water body greasy dirt suspended matter adsorption device

Abstract

The invention discloses an opposite shrinkage type water body greasy dirt suspended matter adsorption device, and belongs to the field of water body greasy dirt treatment. According to the opposite shrinkage type water body greasy dirt suspended matter adsorption device, when adsorbed greasy dirt is nearly saturated, the greasy dirt can penetrate through a limiting channel to enter an inward shrinkage deformation column, a built-in self-hydrolysis water ball is dissolved when meeting oil to release water in the water body greasy dirt suspended matter adsorption device, an effervescence columnis gasified when meeting water, so that a gas gathering film cylinder expands under the extrusion action of gas, on one hand, the buoyancy of the adsorption device is effectively improved, the adsorption device is not prone to sinking into water when the gravity is increased after oil stain adsorption, and it is guaranteed that the adsorption process is normally carried out, and on the other hand,after the effervescence column in the indentation deformation column is gasified, the inward shrinkage deformation column strength is reduced, along with the stretching of the elastic sheet, the deformation is gradually recovered, and the volume and the transverse span of the adsorption device are gradually reduced, so that workers on the shore are effectively reminded of the oil stain adsorptioncondition, the recovery condition caused by unsaturated adsorption is effectively reduced, and the oil stain adsorption efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of water body oil pollution treatment, and more specifically relates to an oppositely contracting water body oil pollution suspended matter adsorption device. Background technique [0002] With the rapid development of the water transportation industry, the risk of water accidents is also increasing. In the waters where ships sail and berth intensively, the discharge or leakage of ships will generate a large amount of floating objects. Floating objects on the water surface include oil slicks, garbage, plant debris, etc., which have the characteristics of large pollution range, long destruction time, and fast diffusion and drift. The large-area (oil) film formed by floating objects on the water surface blocks the normal water-air exchange process, affects the cycle of the biological chain, destroys the ecological balance, and deteriorates the quality of the water body. [0003] In the prior art, when the adsorption t...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide an adsorption device for oily suspended solids in a water body with opposite contraction, when the oily dirt adsorbed by the adsorption device approaches saturation, the oily dirt will pass through the limiting channel and enter the interior. Shrinkage deformation column, the built-in self-decomposing water ball dissolves in oil, and after releasing the water inside, the effervescent column is vaporized when it meets water, so that the gas-gathering film tube expands under the extrusion of the gas, effectively reducing the leakage of gas. On the one hand Thereby effectively improving the buoyancy of the adsorption device, so that the adsorption device is not easy to sink into the water when the gravity becomes larger after absorbing oil pollution. , the stretched shrapnel will gradually restore the deformation, so that the volume and lateral span of the adsorption device will gradually decrease, thereby effectively reminding the staff on the shore of the oil pollution adsorption situation, effectively reducing the occurrence of recovery when the adsorption is not saturated, thereby effectively improving the adsorption device. Efficiency for oil adsorption
