The utility model discloses a kind of ceiling fastener, sound attenuation voltage regulator and sound attenuation shell, including sound attenuation spacer and heat insulation sleeve, there is deslagging gap between two, sound attenuation spacer is equipped with first deslagging hole, front plugging step, rear plugging step and multiple partition steps, step structure separates first, second deslagging passage and is connected by communicating passage, there is deslagging outlet in the outer ring of front plugging step, first deslagging hole is located in first deslagging passage close to front plugging step side.This design makes ash discharge path zigzag, effectively prolongs deslagging distance, significantly enhances sound attenuation effect;At the same time, the partition step is arranged in the sound attenuation spacer, which reduces the processing difficulty, reduces the working hours and cost, and improves the product competitiveness;The extended deslagging path also buffers the ash speed, avoids high-speed injection, and improves the use safety.

The utility model discloses a computer mainframe packing box relates to packing box technical field, and packing box includes one bottom buffer tray, and the middle downward recessed of bottom buffer tray has the accommodation groove, and the accommodation groove is used for the computer mainframe embedding placement, and the groove bottom of accommodation groove upward convex has the bead, and the bead is used for leaning against the support computer mainframe, and the bead part of the front cover below is concave and forms the support groove, and the support groove is used for leaning against the support lower side wall of front cover, and the bead part of the front cover below is not concave and leans against the lower side wall of support computer mainframe, in bottom buffer tray's left and right sides all are provided with side buffer tray, and side buffer tray can turn over and stand up upward, or outwardly fold and spread in bottom buffer tray's outer circumference, when the computer mainframe is placed in the accommodation groove, and side buffer tray turns over and stands up upward, can be respectively padded in computer mainframe's left and right side wall outside. The packing box of the utility model has better buffering effect.

This invention discloses a high-temperature, high-dust-content flue gas purification device, relating to the field of flue gas purification technology. The device includes an adjustable purification structure comprising multiple ceramic filter elements. SCR catalyst components are coated on the surface of each ceramic filter element. A swirling ammonia injection grille is installed at the inlet end of each ceramic filter element. An attitude adjustment mechanism is connected to the purification structure. A PLC control system is electrically connected to the attitude adjustment mechanism, which controls the ceramic filter elements of the purification structure to switch between vertical, inclined, and parallel settings. In the vertical setting, flue gas passes through the filter element in a straight line from top to bottom or bottom to top. In the inclined setting, flue gas passes through obliquely, forming a "Z"-shaped path. In the horizontal setting, flue gas flows laterally through the filter element, and particulate matter is deposited downwards under gravity. This invention solves the problem of low removal efficiency of fine particulate matter, achieving highly efficient purification of high-temperature, high-dust-content flue gas, and is particularly suitable for treating high-emission flue gas under complex operating conditions.
