The flue gas that produces from industrial production in-process is collected and is led into flue gas transfer pipeline, ensure that flue gas flows to the cooling tower in succession, steadily, when reducing flue gas temperature, the dust granule that partly carries can condense and subside in the cooling process, the flue gas that passes through cooling and preliminary purification is sent into in the flue gas desulfurization reactor, the sulfur dioxide in the flue gas turns into the compound that easily handles, the flue gas after accomplishing the desulfurization, can give circulating water or other medium with waste heat transfer through plate heat exchanger, realize the recycle of waste heat, flue gas itself is further cooled down simultaneously, satisfy emission standard, the waste heat of recovery can be applied according to actual demand, thereby improve energy utilization efficiency.
The invention realizes the quick and simple disassembly and assembly of the single heat dissipation plate 2 through the process of the cooperative work of the self-locking mechanism 3 and the extrapolation component 4, and the process particularly relates to the process of releasing the locking state of the movable rod 12 and the positioning rod 13, and the self-locking mechanism 3 is used for driving the movable rod 12 and the positioning rod 13 to synchronously move so as to release the constraint on the heat dissipation plate 2, meanwhile, the extrapolation component 4 precisely applies force to guide the single heat dissipation plate 2 to smoothly move out of the main body frame 1 along the guide plate 14, so that the disassembly and assembly time of the single heat dissipation plate 2 is greatly shortened, and compared with the traditional method, the disassembly and assembly are completed under the condition of not interfering other heat dissipation plates 2, the integral stability and the integrity of the plate heat exchanger are protected, and the potential damage risks caused by maintenance operation are reduced.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
