The utility model discloses a styrene volatile gas discharge pipeline system which comprises a storage tank, an inflation pipeline and an exhaust pipeline, one end of the inflation pipeline and one end of the exhaust pipeline are respectively communicated with the storage tank, an air inlet valve is arranged on the inflation pipeline, an exhaust valve is arranged on the exhaust pipeline, and a timing switch valve is connected with the exhaust pipeline. The timing switch valve is located behind the exhaust valve in the exhaust direction, and a pressure gauge is arranged on the storage tank and matched with the air inlet valve and the exhaust valve. According to the styrene volatile gas exhaust pipeline system, the timing switch valve is connected to the exhaust pipeline, and when the exhaust pipeline exhausts styrene waste gas for a long time, the timing switch valve is opened within a certain interval time, so that external air is conveyed into the exhaust pipeline for replacement; and the air reacts with the styrene waste gas in the exhaust pipeline, so that the blockage phenomenon caused by auto-polymerization of the styrene waste gas in the exhaust pipeline is effectively avoided, and the emission effect of the styrene waste gas is ensured.

An external fan air supply device for a range hood and a ventilation pipeline is composed of an air supply device, a fan, a pipeline and a sealing connecting piece. The air supply device is an innovative core component and can be made of metal or non-metal materials through machining or injection molding and other processes and equipment. The air supply device is simultaneously connected with the fan arranged outside the pipeline and the smoke exhaust pipeline or the ventilation pipeline of the range hood, the flow guide structure is guided through the air supply device during working, airflow needing to be exhausted or conveyed is sucked and guided out, and therefore the oil smoke exhaust or ventilation effect is achieved. Therefore, the problems that the fan is arranged in the range hood or the ventilating duct, oil dirt and dust are prone to being accumulated, potential safety hazards of fire safety electricity utilization are caused, and cleaning and maintenance are inconvenient are solved, and meanwhile the effective space and gas passing ability in the range hood and the ventilating duct are improved. The safety, the practicability and the application scene universality of the method can generate remarkable economic benefits.

This invention belongs to the technical field of diesel engine aftertreatment systems, and particularly relates to a method for calculating urea injection quantity, a dual-SCR system, an engine, and electronic equipment. The calculation method includes: calculating the conversion efficiency of the pre-stage SCR system based on the first urea injection quantity and the first nitrogen oxide content; obtaining an aging correction coefficient based on a first temperature; calculating the first nitrogen dioxide content after passing through DOC based on the pre-stage SCR conversion efficiency and the aging correction coefficient; calculating the second nitrogen dioxide content after passing through DPF based on the first nitrogen dioxide content; calculating the ratio of nitric oxide to nitrogen dioxide in the second nitrogen oxide content; and calculating the second urea injection quantity before the post-stage SCR system based on the ratio. According to the method for calculating the urea injection quantity before the post-stage SCR system of this invention, the second urea injection quantity can be precisely controlled, ensuring emission performance, avoiding ammonia leakage, reducing urea consumption, and improving economic efficiency.

The utility model discloses drying equipment for hermetia illucens cultivation, which relates to the technical field of drying and comprises a drying box, an outer support body is arranged on the inner side of the drying box, a feeding frame body is slidably mounted on the inner side of the outer support body, an outer supporting column is fixedly mounted on the surface of the outer support body, and an auxiliary sliding rod is rotatably mounted on the surface of the outer supporting column. According to the drying equipment for hermetia illucens breeding, the defect that the drying effect is poor due to the fact that single static drying is adopted when traditional hermetia illucens are dried is overcome, and in this way, the good turning effect is guaranteed when the hermetia illucens are dried; the defect of non-uniform drying in the hermetia illucens when the hermetia illucens are stacked is also reduced, and the effect of discharging impurities in the hermetia illucens through a material guide groove when the hermetia illucens are dried is guaranteed, so that the synchronous operation effect of convenient stirring drying and impurity cleaning can be realized when the hermetia illucens are cultured; and the efficient and uniform drying effect during hermetia illucens drying is guaranteed.
