The embodiment of the invention discloses a cracking risk processing method and device, electronic equipment and a computer program product. Wherein the client calls a communication interface to establish at least two communication connections with the server side, calls a java layer communication interface to establish at least one type of communication connection with the server side, and calls a C / C + + language layer communication interface to establish at least one type of communication connection with the server side; respectively generating at least two messages by using the operation data of the client, and respectively sending the at least two messages to the server through the corresponding communication connections; and the server side detects whether the client side has a cracking risk or not by comparing the consistency of the operation data corresponding to the same request identifier. On one hand, the cracking difficulty of a client communication interface is reinforced through a C / C + + language layer communication interface; and on the other hand, through cross validation of the transmission layer, low-cost and high-reliability cracking risk detection is realized, so that the data authenticity is improved.

This invention provides a pyrolysis gas treatment system and method. The system includes a pyrolysis furnace, a dust removal device, and a hot air furnace. The dust removal device includes a cyclone dust collector for removing large-particle-size dust (10 μm or larger) from the pyrolysis gas. The dust removal device also includes a terminal dust collector disposed between the cyclone dust collector and the hot air furnace for removing remaining small-particle-size dust from the pyrolysis gas. The terminal dust collector includes: a terminal cylinder having a terminal inlet for pre-treated pyrolysis gas to enter, a terminal dust outlet for small-particle-size dust to flow out, and a terminal outlet for pyrolysis gas to flow out; a cover sealing the terminal outlet and connected to the hot air furnace via a pipe; a sealing plate held between the terminal cylinder and the cover; a metal microporous membrane filter bag detachably suspended inside the terminal cylinder; and a dust baffle plate disposed on the inner wall of the terminal cylinder, located between the terminal inlet and the metal microporous membrane filter bag. This invention ensures efficient separation and treatment of small-particle-size dust (less than 10 μm) from the pyrolysis gas.

This utility model discloses an air purification mechanism for a ventilation device, including a ventilation housing. The air inlet end of the ventilation housing is connected to an air inlet duct via a flange, and the air outlet end of the ventilation housing is connected to an exhaust duct via a flange. A fan is installed inside the exhaust duct. A mesh protective plate is screwed onto one end of both the air inlet and exhaust ducts. This utility model improves air purification efficiency by sequentially arranging a filter screen, an electrostatic dust collection module, a HEPA filter element, and an activated carbon layer within the ventilation housing. The layered spatial arrangement allows for periodic disassembly, cleaning, or replacement of the filter screen. A self-cleaning structure is provided above the filter screen. A nylon brush moves parallel to the filter screen surface via a synchronous belt, and the negative pressure suction port enhances the cleaning effect. When the differential pressure sensors at both ends detect that the filter screen resistance reaches a preset value, cleaning is triggered, achieving self-cleaning of the filter screen, shortening cleaning time, and improving the filter screen flux recovery rate.

This invention relates to the field of powder coating production technology and discloses an anti-adhesion cooling device for powder coating production. In this invention, a corresponding conveying component is placed inside the external frame. An auxiliary spring-loaded assembly, consisting of a guide groove, pressure rod, connecting shaft, and return spring, allows a soft pad placed on its side surface to intermittently contact the material on the bottom conveyor belt at appropriate times. Even after cooling, the coating material that remains adhered will partially break off under the contact of the soft pad. The spring-loaded contact of the soft pad relies mainly on the interaction between the contact rod, connecting sleeve, abutment rod, and return spring connected to the other end. This device separates material that remains adhered after cooling under mechanical stress; the overall structure is simple and easy to operate.
