The invention relates to a latch needle, which is characterized in that a latch slot (9) of the latch needle (1) is fixed with a latch spring (22) at back. The latch needle (1) is provided with spring support grooves (19, 21) capable of being touched at latch back (7) or the suitable structure capable of containing the ends (25, 26) of the latch spring (22), wherein the spring support grooves (19, 21) are sealed toward the latch back (7), at least the ends (25, 26) of the latch spring (22) are connected with fitting shapes or at least held in the spring support grooves (19, 21) for preventing drop. Therefore, the invention can reduce error sensitivity of latch needle in production. The invention can improve the operation, reliability and service life of latch needle.

The invention relates to a novel device for implanting instruments, which comprises a spreading rod, a spreading rod operating part, a control rod, a moving rod and a moving rod operating part, the spreading rod is a hollow tube, and the spreading rod The distal part of the extension rod can be bent as a whole or in part, the proximal end of the expansion rod is fixedly connected with the operation part of the expansion rod, one end of the control rod is connected to the distal part of the expansion rod, and the other end of the control rod is connected to On the distal part of the moving rod, the proximal end of the moving rod is fixedly connected with the moving rod operating member, and moving the moving rod operating member relative to the spreading rod operating member can realize the spreading The closing and opening of the rod, the release device also includes an anchor needle and an anchor needle push rod, the anchor needle and the anchor needle push rod are arranged in the expansion rod, and the anchor needle The distal end of the push rod is located proximal to the anchor pin. The invention can controlly release the implanted instrument connected thereto, which is beneficial to accurate positioning and improves the success rate of operation.

The invention discloses a preposing cyclone pre-dedusting SCR flue gas denitration technique. The flue gas extracted from a boiler economizer (12) primarily passes through a high temperature resistantcyclone separator (6), then passes through a flue gas current equalizer (7) and a static mixer (2) to unify the flow direction of the flue gas evenly; meanwhile, the flue gas after being mixed evenlywith ammonia is preprocessed before reacting with a catalyst of an SCR reactor (3); finally, the flue gas is output after the temperature is reduced through an air preheater (4) and the flue gas is dedusted through an electrical precipitator (5). The invention reduces the volume of the catalyst and the SCR reactor, reduces the requirements of the support, eliminates an SCR bypass and greatly reduces engineering cost of the SCR; meanwhile, the invention also prolongs the service life of the catalyst and the cleaning period of the air preheater without installing a soot blower or prolonging theperiod of sootblowing.

The invention relates to a billet or bloom continuous casting system, comprising a mold for forming a metal strand and a strand guide (2) connected to the mold (1) for supporting and guiding the metal strand, wherein the strand guide is formed by multiple strand guide segments (3a, 3b, 3c, 3d, 3e, 4), and each strand guide segment is supported via a segment support frame (7, 8) in the system support framework of the continuous casting system, and a first segment support frame (7) directly following in the strand guide of the mold supports at least two strand guide segments. In order to minimize the maintenance expense, the first strand guide segment (3a, 3d) directly following the mold is detachably mounted on the first segment support frame on substantially vertical support surfaces (12), and is configured such that the same can be installed into and uninstalled from the continuous casting system independently of the subsequent strand guide segments (3b, 3c, or 3e), and at least the last strand guide segment (3c, 3e) supported on the first segment support frame (7), exclusively together with said frame, forms an assembly unit that can be installed and removed.

The invention discloses an I-type impact air flow attenuator. The I-type impact air flow attenuator comprises an air flow buffering cavity, wherein an air inlet pipe and an air outlet pipe which are communicated with an inner cavity of the air flow buffering cavity are arranged at the two ends of the air flow buffering cavity; straight pipe sections of an emptying pipeline are communicated by the air inlet pipe and the air outlet pipe on the air flow buffering cavity; the air inlet pipe and the air outlet pipe on are arranged on a same straight line and are distributed in an I shape in the air flow buffering cavity. According to the I-type impact air flow attenuator, the properties of impact air flow and the emptying pipeline are considered comprehensively, basic principles of an interference type air flow buffer, a porous plate and a pore plate acoustic filter are integrated and extraction flow requirements of the emptying pipeline and the dynamic property of the impact air flow are considered comprehensively; the I-type impact air flow attenuator can be mounted on the straight pipe sections of the emptying pipeline outside a safety valve horizontally or vertically; the air flow buffering cavity is arranged, and the turning parts of the emptying pipeline are communicated by the air inlet pipe and the air outlet pipe on the air flow buffering cavity, so as to realize the effects of dissipating the energy of the impact air flow, reducing a coupling effect of the pipelines and guaranteeing the requirements of extraction flow.
