Shell tubular secondary spray condenser for cooling tower

Abstract

The invention discloses a shell tubular secondary spray condenser for a cooling tower. The shell tubular secondary spray condenser comprises condensing coils which are distributed in rows. The condensing coils comprise inner coil bodies and outer coil bodies. Upper ports of the outer coil bodies communicate with an upper water collecting cavity, and upper ports of the inner coil bodies communicatewith an upper flow collecting cavity. The upper flow collecting cavity is formed in the upper water collecting cavity. Lower ports of the outer coil bodies communicate with a lower water collecting cavity, and lower ports of the inner coil bodies communicate with a lower flow collecting cavity. The lower flow collecting cavity is formed in the lower water collecting cavity. The upper flow collecting cavity communicates with a fluid inlet pipe, and the lower flow collecting cavity communicates with a fluid outlet pipe. A branch pipe is arranged at the side edge of the lower water collecting cavity, and a water guiding pipe is arranged on the upper water collecting cavity. The upper end of the water guiding pipe is connected with a water collecting tank, and secondary spray heads are distributed on the bottom face of the water collecting tank. The water collecting tank is horizontally arranged above the condensing coils. According to the shell tubular secondary spray condenser, the heat-dissipating area is larger, full-contact-type water cooling and indirect-evaporation-type cooling can be achieved, the cooling efficiency of the condenser is improved greatly, and the efficient cooling purpose is achieved.

Description

Technical field [0001] The invention belongs to the technical field of cooling towers, and specifically is a shell and tube type secondary spray condenser for cooling towers. Background technique [0002] The existing condenser for cooling towers such as figure 1 As shown, the condenser coil adopts a straight pipe structure with elbows connected at both ends to form a circuitous and curved structure. The external cooling water is sprayed from the upper end down on the upper surface of the condenser to perform evaporative cooling. Due to structural limitations and cooling The limitation of the method leads to the limited cooling efficiency of this kind of condenser, which cannot be broken. If the cooling efficiency is to be improved, the condenser is required to be made larger, so that the larger the cooling tower body, the higher the cost, the floor space and the overall The volume is also larger. Summary of the invention [0003] The purpose of the present invention is to solve ...

[0002] Existing condensers for cooling towers such as figure 1 As shown, the condenser coil adopts a straight pipe structure, and the two ends are connected with elbows to form a circuitous and curved structure. The external cooling water is used to spray down on the upper surface of the condenser from the upper end to perform evaporative cooling. Due to structural limitations and cooling Due to the limitation of the method, the cooling efficiency of this condenser is limited and cannot be broken through. If the cooling efficiency is to be improved, the condenser is required to be made larger, so that the larger the cooling tower body, the higher the cost, the floor area and the overall The volume is also bigger
