The utility model provides an efficient desulfurization wastewater clarification device which comprises a clarification tank main body, and an upper heat exchanger, a heat exchange tube and a lower heat exchanger are sequentially arranged in an inner cavity of the clarification tank main body from top to bottom; the bottom of the heat exchange pipe is connected with a pipeline bracket, and clarification tank filler is arranged at the top of the heat exchange pipe; wherein the other end of the pipeline bracket is connected with the bottom of a sedimentation tank in the clarification tank main body; a sludge outlet is formed in the bottom of the sedimentation tank; the device can automatically clean and operate, is high in automation degree, and can specifically and efficiently precipitate desulfurization wastewater compared with a traditional precipitation tank; strong brine is used as a heat exchange medium for heat exchange, so that the temperature of the strong brine is increased, heat needed by temperature rise of the rear-end evaporation section is reduced, and the energy-saving effect is achieved.

This invention belongs to the field of medical suture technology, and particularly relates to a medical suture barb heat-fusion device, comprising a first traction component, a second traction component, a positioning component, a heat-fusion component, and a cutting component. The first and second traction components are used to drive the suture to linear horizontal movement and rotation from both ends. The positioning component provides effective positioning support for the linearly horizontally moving suture. The heat-fusion component softens the suture to a suitable degree. The cutting component cuts barbs on the softened suture. This invention has a simple structure, is easy to operate, and has low maintenance costs.
