Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a circulating cooling tower used in chemical production. Background Art

[0002] The function of a cooling tower is to exchange heat between cooling water carrying waste heat and the air within the tower, transferring the waste heat to the air and dissipating it into the atmosphere. Traditional circulating cooling towers used in chemical production adopt an open cooling mode, that is, waste hot water generated during chemical production is sprayed into the cooling tower through nozzles, and dissipated by fans. However, when used in cold winters, water vapor often splashes onto low-temperature areas such as the heat dissipation grille during the aforementioned process, causing ice to form inside the cooling tower, affecting industrial production.

[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1-3This embodiment provides a circulating cooling tower for chemical production, which includes a tower body 1, two sets of heat dissipation grilles 2 fixedly installed on the outer wall of the tower body 1, a tower column 3 fixed at the bottom of the tower body 1, a chemical waste liquid inlet pipe 4 arranged through the side wall of the tower body 1, an output pipe 5 with the liquid outlet end extending outside the tower body 1, a plurality of heat dissipation fins 6 arranged vertically in the tower body 1, a pipe assembly 10 fixedly arranged through the plurality of heat dissipation fins 6, and a fan C7, a fan A8, and a fan B9 installed in the tower body 1.

[0027] The chemical waste liquid inlet pipe 4 is located above the heat dissipation grille 2, and the outlet end of the chemical waste liquid inlet pipe 4 is located at the central axis of the tower body 1. The output pipe 5 is fixedly connected to the bottom of the tower body 1 through the outlet pipe 5.

[0028] The pipe assembly 10 is fixedly connected between the chemical waste liquid inlet pipe 4 and the outlet pipe 5. The pipe assembly 10 is located within the tower body 1 and includes six groups of branch pipes arranged in a ring array. In this embodiment, the pipe assembly 10 adopts a structure in which six groups of branch pipes are arranged in a ring array. Compared with a single diversion channel, this embodiment provides six diversion channels, each of which penetrates the heat sink 6, thereby maximizing the utilization of the heat transfer surface of the heat sink 6, increasing the heat transfer area, and thus improving the cooling efficiency.

[0029] Fans C7, A8, and B9 are all secured to the tower body 1 via brackets, with fan C7 positioned above the chemical waste liquid inlet pipe 4. The heat sink 6 and tower body 1 are not in contact, and fans A8 and B9 are symmetrically positioned on opposite sides of the heat sink 6. Fan A8 is positioned directly opposite one set of heat sink grilles 2, while fan B9 is positioned directly opposite the remaining set of heat sink grilles 2.

[0030] The cooling tower of this embodiment works as follows:

[0031] First, wastewater generated during chemical production enters tower body 1 through chemical wastewater inlet pipe 4, is diverted through piping assembly 10, and finally flows out of tower body 1 through outlet pipe 5 for reuse. During this process, as the wastewater passes through piping assembly 10, heat is conducted through heat sink 6. Fans C7, A8, and B9, combined with fans C7, A8, and B9, blow air in three directions through piping assembly 10 to accelerate convection, thereby achieving rapid cooling.

[0032] Conventional circulating cooling towers for chemical production employ an open cooling mode, where wastewater generated during chemical production is sprayed into the cooling tower via nozzles and dissipated by fans. However, during cold winter months, water vapor often splashes onto cooler areas, such as the radiator grille 2, causing ice to form within the cooling tower, impacting industrial production. Consequently, the iced areas need to be cleaned, and manual de-icing can be prone to accidents, reducing the safety of the cooling tower. Therefore, the circulating cooling tower of this embodiment employs a fully enclosed heat dissipation structure. Specifically, the industrial wastewater is transported entirely within a closed pipeline formed by the chemical wastewater inlet pipe 4, outlet pipe 5, and piping assembly 10. This allows for simultaneous cooling during the transport process, overcoming the ice formation problem associated with open cooling modes due to low temperatures.

[0033] In summary, the circulating cooling tower for chemical production in this embodiment has the following advantages compared to traditional cooling towers: the circulating cooling tower in this embodiment adopts a structural design of closed pipes + heat conduction + air blast to accelerate convection, so that the waste hot water generated during chemical production is directional transmitted and cooled in an integrated manner, achieving rapid cooling, and overcoming the problem of freezing in a low-temperature working environment when the waste hot water is sprayed into the cooling tower through a nozzle for cooling. It can continuously treat industrial hot wastewater in low-temperature areas, thereby improving the efficiency of industrial production.

Those skilled in the art may also choose other nouns to describe the names of the various components of the present invention.
