The present invention relates to a device capable of rising heat exchange efficiency and boiler using said device. It includes a circular tube whose tube end is closed, on the side wall of the circular tube several water inlet holes are set, every water inlet hole is equipped with water guide plate, and the plate surface of every water guide plate and tangential direction of circumference of circular tube are formed into 10deg.-50deg.angle, and another end of said circular tube is equipped with a water outlet. Said structure can effectively raise heat-exchange efficiency.

The invention discloses a device for silencing, ventilation and light collection. The device comprises a quadrangle silencing frame filled with a silencing material, wherein interior of the silencing frame is divided into a ventilation and silencing room and a light collection and silencing room; the ventilation and silencing room is divided into three successively connected rooms including a first room, a second room and a third room, and the first room and the third room are opened and the second room is sealed on the face of the ventilation and silencing room located outdoors; the indoor side of the ventilation and silencing room is closed, and connection edges between the first room and third room and the second room are set as ventilated grates or nets; at joints of the ventilation and silencing room and the light collection and silencing room, the first room and the third room are sealed by silencing edges, and the second room is open; and an outer window body is disposed on the outdoor face of the light collection and silencing room, and an inner window body with an openable structure is disposed on the face towards indoors. According to the invention, light collections effects are the same as light collection effects of a common window; dual-layer window sealing is used; sound isolation effects are better; ventilation is quick; ventilation effects are good; the silencing structure achieves perfect silencing effects; the structure is simple; the cost is low; and use is convenient.

The invention belongs to the technical field of organic silicon production, and in particular to a device for recycling waste of organic silicon synthesis. The device comprises an upper seal head, a cylindrical barrel, a cone-shaped cylinder large in the upper part and small in the lower part, a residue outlet and a stirring module, wherein the stirring module comprises an air cylinder, support plates, connecting rods and arc-shaped sliding blocks; a group of support plates are arranged at intervals at the middle part of a push rod of the air cylinder; a group of connecting rods radially arranged along the support plates are arranged at outer rings of the support plates; one ends of the connecting rod are fixedly connected at one sides of the arc-shaped sliding blocks; elastic films are arranged in through grooves; one sides of the elastic films are fixedly connected with one sides of the through grooves; the other ends of the elastic films are fixedly connected with sliding plates; through notches are formed in the middle parts of the elastic films; and the sliding plates are used for controlling the closing or the opening of the notches. The device disclosed by the invention hasthe beneficial effects that the support plates are driven to move up and down by the push rod and when the arc-shaped sliding blocks slide to the cylindrical barrel, the sliding plates move outwards and the notches are opened, so that the flow path of organic silicon slag slurry is increased, the convection of the organic silicon slag slurry is more sufficient and the distillation efficiency of high-boiling point substances is improved.
