Abstract

A device for cleaning a plate type vessel is provided. It includes a cleaning unit (12), a first operating unit and a second operating unit. The first operating unit moves the cleaning unit along the length direction (Y) of the plate type vessel (2), which executes the horizontal cleaning operation on the inner surfaces of the lateral walls of the plate type vessel along the length direction. While executing the horizontal cleaning operation, the second operating unit drives the cleaning unit to execute the vertical cleaning operation on the inner surfaces of the lateral walls of the plate type vessel. A system for cleaning a plate type vessel is also provided. Multiple said devices for cleaning the plate type vessel are connected together by joint levers (3). The system enables cleaning multiple plate type vessels simultaneously by moving the devices all together along the length direction of these plate type vessels arranged in line. The invention can be used to clean a plate type vessel with narrow width and multiple layers, exhibiting the advantages of good cleaning effect and high efficiency.

Abstract

A method for effectively controlling harmful organisms in the large-scale culture of microalgae comprises the following steps: (1) determining the harmful species causing pollution to the microalgae in culture, and the acid and alkali tolerance level of said harmful species; and (2) adjusting the pH value of a microalgae culture system according to the different acid and alkali tolerance levels of the harmful organisms; when the harmful organisms are determined to be killed or inhibited effectively, adjusting the pH value back to be suitable for the normal growth of the microalgae. After the treatment, common harmful protozoa in the culturing processes of most microalgae (green algae, blue algae and variegated algae) can be controlled effectively, and the method is also effective against certain miscellaneous algae pollutions.

Abstract

An oil shale exploitation method comprises: forming a gas inlet pipeline (1) and a gas outlet pipeline (3) in an oil shale; forming a gasification channel (5) that connects the gas inlet pipeline and the gas outlet pipeline in the oil shale; feeding a combustible gas and oxygen into the well through different gas inlet pipelines, and then igniting, in an aerobic environment, the combustible gas fed into the well at the lower opening of the pipeline for conveying the combustible gas, so as to heat the oil shale; and recycling through the gas outlet pipeline an oil-gas mixed product formed after thermal decomposition of kerogen in the oil shale. The method has simple process and low energy consumption, and is capable of heating kerogen in the shale bed, thereby exploiting an oil shale mineral layer to obtain oil and gas products more economically and reasonably.
