Description

Spiral winding tube type heat exchanger of condensing system Technical Field The utility model relates to the technical field of tubular heat exchangers, in particular to a spiral winding tubular heat exchanger of a condensing system. Background The existing shell-and-tube condenser has the problems of low heat exchange efficiency, large volume, easy scaling and the like. Although the heat exchange efficiency of the conventional spiral winding tube heat exchanger is improved by extending the flow channel, the problems of flow dead zone, condensate accumulation affecting heat exchange, vibration abrasion of the tube bundle and the like caused by fixed tube bundle spacing exist in the conventional structure. Disclosure of utility model In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a condensation system's spiral winding tubular heat exchanger, includes the body, body one end sets up the front end, and the other end sets up the rear end, and the front end is connected with preceding ring flange cooperation, and the rear end is connected with the cooperation of rear ring flange, and body front end both sides set up preceding siphunculus, set up fixing bolt, middle part siphunculus and side siphunculus on the ring flange, middle part siphunculus and the inside UNICOM of body, body one side sets up the body valve, and body inside both ends set up the metal disc, and the metal disc outside sets up a plurality of winding pipes, side siphunculus and the inside UNICOM of a plurality of winding pipes, set up spiral sheetmetal on the body inner wall, spiral sheetmetal is connected with a plurality of winding pipes. Preferably, an inner pipe body is arranged in the pipe body, the front through pipe is communicated with the inner pipe body, a groove is arranged between the pipe body and the inner pipe body, and the groove is communicated with the side through pipe. Preferably, the front flange plate is provided with a plurality of holes, the front flange plate is connected with the front sealing head through bolts, the rear flange plate is provided with a plurality of holes, and the rear flange plate is connected with the rear sealing head through bolts. Preferably, the metal disc is connected with the inner side of the inner tube in a matched manner, a plurality of small holes are formed in the metal disc, and the spiral metal sheet is fixedly connected with the inner tube. Compared with the prior art, the utility model has the following beneficial effects: The utility model improves the heat exchange efficiency, namely, the reverse winding and variable spacing design ensures that the medium forms turbulence and improves the heat exchange coefficient, the anti-scaling spiral fin and round tube design reduces the detention area and the scaling rate, the structural stability is that the flange plate support and wave spacing piece can inhibit the vibration of the tube bundle, and the condensate is quickly separated, thus improving the gas-liquid separation efficiency.
