The invention provides an experimental device for flow-induced vibration of a tube bundle. The experimental device for flow-induced vibration of the tube bundle comprises a shell-shaped flow-induced vibration experimental device. The tube bundle supported by a supporting plate is arranged in the flow-induced vibration experimental device. The two ends of the flow-induced vibration experimental device are flanges. An acceleration sensor is arranged in the flow-induced vibration experimental device. The upper portion of the flow-induced vibration experimental device is connected with a water pump through a pipeline which is provided with a pressure gauge, a flow meter and a first valve in sequence. The water pump is further connected with a water tank through a pipeline provided with a second valve. The water tank is connected with the bottom of the flow-induced vibration experimental device through a pipeline provided with a third valve. The portion, between the water tank and the third valve, of the pipeline and the portion, between the flow meter and the first valve, of the pipeline are connected with each other through a pipeline provided with a fourth valve. The experimental device for flow-induced vibration of the tube bundle is really effective.

The invention discloses a production method of an efficient, energy-saving and environment-friendly formed and carbonized material. The method comprises the following steps of performing dehydration, drying and powdering on water-washed clean coal, compression-molding the powder through a pelletizer, and then crushing the molded powder into formed materials with a grain size of 2-10 mm through a straightening granulator; feeding the formed materials into a carbonizing converter from the tail portion, performing segmented and temperature-controlled heating inside the carbonizing chamber of the carbonizing converter from the room temperature to 550-600 DEG C, and performing cooling and discharging carbonized materials from the converter end of the carbonizing converter. Retorting gas volatilized during the low-temperature dry distillation process of the formed materials can move in the same direction with the raw materials under negative-pressure control and enter a high-temperature incinerator via a converter end special gas passage of the carbonizing converter for incineration; high-temperature gas generated by the incineration can enter the heating chamber of the carbonizing converter through a gas inlet pipe at the converter end of the carbonizing converter and move reversely relative to the formed materials to indirectly heat the formed materials and further to achieve low-temperature distillation effects. The production method of the efficient, energy-saving and environment-friendly forming carbonization material improves the quality of the carbonized material and meanwhile reduces energy consumption and emission to really achieve energy conservation and environmental protection.

The invention relates to a solar photovoltaic assembly which comprises a solar panel, a section material and a cover plate. The section material comprises a section material main body, a bearing plate, a first extension, a second extension, a third extension and a split block, wherein one part of the section material main body is vertically arranged, the bearing plate is arranged at one end of the section material main body and forms a 90-degree angle with the section material main body, the first extension and the second extension both extend from the bearing plate and form 90-degree angles with the bearing plate, the height of the first extension in the vertical direction is lower than that of the second extension, a space is formed by the first extension, the second extension, the bearing plate and the solar panel to be used for accommodating waterproof glue, the third extension extends from the section material main body and is arranged opposite to the bearing plate, the split block is arranged at one end of the third extension and extends from the third extension, and the split block is horizontally arranged. After the solar photovoltaic assembly is spliced well, the solar photovoltaic assembly can be built into an integrated roof of a solar photovoltaic building, and effects of power generation, waterproofness, dust prevention, energy conservation and environmental friendliness are achieved.
