Above, it can also reduce the impact on the surrounding environment of the cabinet level and reduce the explosion loss; it can also reduce the impact on other parts of the cabinet caused by the explosion of the electrical cabinet, and reduce the impact force caused by the explosion; thus reducing The damage caused by the explosion to the surrounding people or objects, in order to achieve the purpose of explosion protection.

The invention relates to a double-trigger umbrella type oil and gas pipeline explosion-proof valve, which includes a valve body, a bracket, a valve stem guide rail, a valve stem group, an explosion-proof cover, a left mechanical response mechanism, a right mechanical response mechanism, a locking mechanism, a sensor Warm action mechanism, the two ends of the valve body are the valve diameter, the valve stem guide rail is set between the left mechanical response mechanism and the right mechanical response mechanism, the valve stem guide rail is located in the valve body, the valve stem group is surrounded by the valve stem guide rail, and the valve stem group is outsourced A layer of explosion-proof cover; the left mechanical response mechanism and the right mechanical response mechanism are installed in the center of the valve diameter at both ends of the valve body through brackets. When the pipeline burns or explodes, the limiting plate at one end of the present invention is released and moves quickly in the guide rail, so that the valve stem group shrinks rapidly, so that the valve disc presents an open posture; when the limiting plate moves to the limit distance, It is locked with another limit plate through the lock block and the lock cavity, and cannot continue to move. At this time, the valve disc is close to the inner wall of the valve body, blocking flame or shock wave, and achieving the effect of flameproofing.

The invention provides an explosion-proof lamp comprising an upper shell, a lower shell cooperating with the upper shell, a driver and a lamp tube are arranged in the lower shell, the lamp tube is electrically connected to the driver, and the locking device is locked. The switch mechanism of the upper shell and the lower shell. The switch mechanism includes multiple sets of rotating assemblies rotatably arranged on the first side of the lower case, and multiple sets of locking assemblies arranged on the second side of the lower case. The explosion-proof lamp also includes a sealing assembly, which is used for sealing the upper shell and the lower shell. The above-mentioned explosion-proof lamp uses a sealing component to seal the upper case and the lower case, and cooperates with the rotating component and the locking component to lock the upper case and the lower case. At this time, the gap between the upper shell and the lower shell is very small, which can limit the explosive gas, steam or mist from entering the interior of the lamp body to achieve the purpose of explosion protection. When the locking component is released, the upper shell can rotate around the rotating component, which facilitates the opening of the lamp, and the operation is simple and economical.

An explosion-proof safety valve for a lithium battery, comprising a valve body (2), a filter (1) that allows gas to pass through but not liquid, a rubber cover (3) that is resistant to electrolyte corrosion, a cover (4), and a rubber sleeve The cover (3) is an inverted cylinder-shaped structure with a top-capped longitudinal section in the shape of "冂". The bottom of the valve body (2) is open, and an annular bead (21) protrudes upward in the valve inner chamber (22). The inner cavity (23) of the protruding ring (21) runs through up and down, and the lithium battery explosion-proof safety valve also includes an annular pressure ring (5), an annular pressure ring (5), a filter disc (1), and a rubber cover (3) from top to bottom The bottom is placed in the inner cavity (22) of the valve in turn, the rubber cover (3) is buckled and arranged on the annular bead (21), the cover (4) is covered on the top surface of the valve body (2), and the cover ( 4) There is a ventilation gap (41) between the bottom surface and the top surface of the valve body (2) for the valve inner cavity (22) to communicate with the outside world, and the filter (1) is provided with a groove that can be broken through if the air pressure is higher than the set value bottom annular groove (11). Its advantages are: sensitive response to pressure, high adaptability and good explosion-proof effect.

The invention relates to a filtering capacitor equipped with an explosion-proof apparatus. The filtering capacitor comprises a shell, a capacitor core group, a cover board, a first electrode electrically connected with the capacitor core group, a second electrode electrically connected with the capacitor core group, insulating oil and the explosion-proof apparatus, wherein the explosion-proof apparatus comprises a pressure switch and an alternating current contactor; a drainage tube is arranged at the bottom of the pressure switch; a downwardly convex film sheet is arranged at the bottom of the drainage tube; the alternating current contactor comprises a coil, a first contact switch and a second contact switch; the circuit where the coil is located is connected with the circuit where the pressure switch is located in series; the circuit where the first contact switch is located is connected with the first electrode in series; and the circuit where the second contact switch is located is connected with the second electrode in series. The filtering capacitor equipped with the explosion-proof apparatus is simple to overhaul and troubleshoot, convenient to use, good in explosion-proof effect, high in safety, and high in application value.

The invention relates to a process for preventing fogging and explosion of coal dried tail gas in dry bag-type dust removal process. The process comprises the following steps of: sucking high-dew-point and low-oxygen-content dust-containing dried tail gas which is exhausted from the tail of a drier into a bag-type dust remover by a draught fan for gas-solid separation; discharging separated dust which is deposited at the bottom of the bag-type dust remover by a star discharger; drawing purified carrier gas and water vapour to a safety place by the draught fan for exhausting; drawing a part ofthe tail gas from an outlet pipeline of the bag-type dust remover by a circulating fan; mixing a part of air which is heated by an air heater; and heating the air by using a circulating heater, and mixing into an outlet tail gas pipeline of the drier. The aim of preventing the fogging of the tail gas in the dried tail gas treatment process is fulfilled by cyclically heating the part of the tail gas and mixing a certain amount of hot air, the aim of preventing the explosion is fulfilled by controlling the content of oxygen in an outlet of the bag-type dust remover, and the fogging of the driedtail gas in the bag-type dust remover is prevented during explosion prevention.
