The invention relates to a coke oven raw gas rising pipe waste heat recovery device, which belongs to the technical field of heat energy recovery and utilization. The device includes upper and lower headers surrounding the inner wall of the coke oven raw gas rising pipe, and the upper and lower headers respectively lead a group of separate heat pipes through the inner wall of the coke oven raw gas rising pipe to connect the upper and lower headers to absorb heat. At the same time, they communicate upwardly with the two ends of the heat release end of the separated heat pipe through connecting pipelines, and the heat release end of the separate heat pipe is located in the heat exchange drum. The invention realizes rapid recovery of heat, and because the separated heat pipe is adopted, the arrangement is convenient, and by increasing the pressure of steam production, the wall temperature of the heat pipe can be ensured to be above the dew point of raw gas tar, so no coking problem will occur; and the separated heat pipe The amount of working medium in the tube is small, even if the heat tube is damaged, the steam-water mixture in the entire steam drum will not leak into the carbonization chamber like the water jacket, so it will not cause safety accidents and can ensure the safe operation of the coke oven.

The invention belongs to the technical field of air conditioners, and aims to solve the problem that an existing air conditioner with a dust removal purification module is prone to generate condensation phenomenon. Therefore, the invention provides a control method for the air conditioner; the air conditioner comprises an indoor unit and a purification module; the control method comprises the steps that the air conditioner is enabled to execute a purification mode; an air outlet temperature of the indoor unit is acquired; and the position of the purification module is adjusted according to theair outlet temperature of the indoor unit. When the air conditioner executes the purification mode, the air outlet temperature of the indoor unit is acquired, then the position of the purification module is adjusted according to the air outlet temperature, so that the condensation phenomenon of the indoor unit when the temperature is too low is avoided; and then the water blowing phenomenon is avoided, the indoor environment cannot be polluted, safety accidents cannot be caused, and the user experience is improved.

A system for prohibiting a vehicle from driving when a door is opened comprises a hydraulic pump, an ejector rod roller valve, a filter, an air bag, a fuel tank, a safety valve, a gear-selecting directional valve, a forward gear clutch, a reverse gear clutch and a control mechanism. An ejector rod of the ejector rod roller valve is connected with a door of the vehicle cab, the air inlet port P ofthe ejector rod roller valve communicates with the air bag, the execution port A of the ejector rod roller valve communicates with the air control port K of the control mechanism, the oil inlet port Pof the control mechanism communicates with the oil outlet port of the hydraulic pump, the execution port A of the control mechanism communicates with the oil inlet port P of the gear-selecting directional valve, the execution port A of the gear-selecting directional valve communicates with the forward gear clutch, the execution port B of the gear-selecting directional valve communicates with thereverse gear clutch, and the oil inlet port of the hydraulic pump communicates with the fuel tank through the filter. By applying the system, the vehicle cannot advance or reverse even if the gear-selecting directional valve is operated when the driver does not close the cab door, so that no accident is caused.

The invention discloses a pen container for students. The pen container comprises a rectangular container body, a first separation plate with the hollow interior is fixedly arranged in the container body, a groove is formed in the position, located on the lower side of the first separation plate, of the container body, a storage drawer is movably mounted in the groove, a first vertical sliding groove is formed in one side of the container body, a first sliding block is movably connected to the interior of the first sliding groove, and one side, away from the container body, of the first sliding block is movably connected with a container cover through a hinge; and the interior of the container wall of the container body is hollow, a second transverse sliding groove is formed in the side face of an inner cavity of the container wall, and a second sliding block is movably mounted in the second sliding groove. According to the pen container for the students, after pens, erasers and other stationery are put into the container body, a container cover is located on the top of the container body through the joint effect of the first sliding block and the hinge, then the container body is covered with the container cover, carrying is convenient, convenience and rapidness are high, it is ensured that pointed objects like the pen cannot cause the safety accidents, and safety of the students is facilitated.
