The invention discloses a negative pressure waste gas discharge disinfection and sterilizer and a manufacturing method thereof, which comprises a housing, a gas pipeline, a junction box and a heating element. Both ends of the housing are provided with protective covers, and the size of the opening of the protective cover is along the The center of the shell gradually decreases toward the end, and the inner cavity of the protective cover communicates with the gas pipeline. The method includes: a, installing a protective cover welding device; b, welding to obtain a protective cover with an initial shape; c, welding an inner cavity in the protective cover with an initial shape; d, cutting to obtain a formed protective cover; The sealing plate is welded and fixed; f, the protective cover is painted; g, the protective cover is respectively welded on both ends of the shell; h, the bottom of the junction box is sealed on the shell. The invention can avoid the phenomenon of gas leakage, reduce the temperature of the exhaust at the same time, improve the safety, and increase the processing air volume; and solve the technical problem that the inside of the truss-shaped protective cover is not easy to weld, and increase the vertical pressure bearing of the protective cover Capability, can be welded in batches to get the protective cover.

The invention provides a control method for an engine starting system. The control method includes the steps that: 1, when an engine starts, an electronic control unit controls an air jet guide rail assembly to supply hydrogen fuel to the engine and ignite to start up; 2, after then engine starts, the electronic control unit detects the operating time of the engine in real time, when it is detected that the operating time of the engine is time T, the electronic control unit control the air jet guide rail assembly to close and control an oil jet guide rail assembly to open, wherein the time T is the operating time of the engine when a three-way catalyst reaches an initiation temperature. According to the control method for the engine starting system, the hydrogen is adopted as the fuel of the starting system of the engine, so that the problem that the engine is difficult to start under the low temperature environment is solved, and meanwhile the ECU (Electronic Control Unit) switches a fuel supply system according to the operating time of the engine when the three-way catalyst reaches the initiation temperature, thus further reducing discharge of pollutant when the engine starts.

The invention relates to a heat accumulating type slewing air preheater which comprises an upper air chamber, a lower air chamber and a middle slewing heat accumulating device. The slewing heat accumulating device comprises a slewing bearing, a speed reducer and a slewing body, wherein the slewing bearing is arranged at the top of the lower air chamber, the speed reducer is arranged on one side of the slewing bearing and drives the slewing bearing to rotate, and the slewing body is arranged on the slewing bearing and rotates along with the slewing bearing. A liquor condensate collection and neutralization system is arranged at the bottom of a cold smoke chamber of the lower air chamber and comprises a mixed precipitation chamber and a heavy metal processing chamber, wherein limestone alkaline particles are arranged in the mixed precipitation chamber, the heavy metal processing chamber is connected with a discharging pipe, and processed liquor condensate is discharged out through the discharging pipe. The slewing bearing drives the slewing body and a heat accumulating body to rotate to complete heat exchange between high-temperature smoke and cold air, pollutants such as acid liquid containing nitration and sulfide and produced by condensation of low-temperature smoke can be collected and neutralized through the liquor condensate collection and neutralization system, and therefore, air pollution caused by smoke discharged out of a heating furnace is reduced.

The present invention relates to a single gun oil-gas recovery separator, which is characterized by at least comprising a filter cylinder, a gas inlet joint and a connection joint, wherein an accumulation filtration unit is fixed inside the filter cylinder, the accumulation filtration unit is packaged in the filter cylinder through the upper cover and the lower cover by both ends of the filter cylinder, the upper cover is connected with the gas inlet joint, the lower cover is connected with the connection joint, the gas inlet joint and the connection joint are arranged on both ends of the filter cylinder, the gas inlet joint, the filter cylinder, the accumulation filtration unit and the connection joint form a first filtration body, and the separated gas-liquid enters from the gas inlet of the gas inlet joint and is discharged from the connection joint. The single gun oil-gas recovery separator has characteristics of low cost, simple structure and good process, wherein the existing recycling equipment is completely utilized so as to reduce the engineering cost.

The invention discloses an air intake propulsion device for a vector vehicle, specifically relates to the field of automobile manufacturing, comprising an outer air intake guide cylinder and a guide flow pipe, a sliding guide rail is fixedly installed on the inner side of the outer air intake guide cylinder, and a guide rail is slidingly installed on the inner side of the sliding guide rail. The flow plate, the other side of the flow guide plate is fixedly connected with the guide shaft cylinder in the outer air intake guide cylinder, the inner side of the guide flow pipe is fixedly installed with a bearing frame, the inner side of the bearing frame is pierced with a transmission shaft rod, and the transmission shaft rod The upper and lower ends of the upper and lower ends are respectively fixedly connected with an intake drive fan blade and a wind blowing turbofan. In the above scheme, the air intake propulsion device of the vector car is installed in the air intake channel between the air filter and the throttle valve to increase the air intake. After fusion, a variety of vortices are formed, which makes the air and fuel more fully stirred, and the combustion is more complete, avoiding the accumulation of carbon deposits, thereby further improving the combustion efficiency.
