Description

Technical Field

[0001] This utility model relates to the field of chemical cooling equipment technology, and in particular to a high-efficiency and energy-saving chemical process cooling water circulation device. Background Technology

[0002] With the rapid development of modern industry, many processes (such as chemical, metallurgical, power, and pharmaceutical industries) generate a large amount of heat. These heats must be removed in a timely manner through cooling systems to ensure the normal operation of equipment and the stability of processes.

[0003] In the prior art, patent publication number CN220119641U discloses a cooling water circulation device, relating to the field of cooling water cooling technology. It includes a housing, inside which a circulating water tank and a cooling tank are installed. The circulating water tank has a water trough inside, and a water pump is installed on one side of the tank. The input end of the water pump extends into the water trough, and the output end of the water pump is fixedly connected to a cooling pipe. The beneficial effects of this utility model are: This cooling water circulation device, through an electric heating plate installed inside the circulating water tank, can, during non-cooling periods, cooperate with a feeder on the top of the tank to mix chemical substances such as baking soda with heated water. As the water flows, it reacts with the scale adhering to the cooling pipe, facilitating scale removal. Furthermore, the tank is equipped with a filter screen and a stirring shaft, which helps to accelerate the mixing of chemical substances and water, and intercept impurities in the water flow, preventing blockages and ensuring smooth water flow.

[0004] Although the above-mentioned cooling water circulation device can remove scale through the setting of circulating water tank and water pump, it still has the following shortcomings in practical applications: Traditional cooling water circulation systems usually use a single-stage heat exchanger to cool down the high-temperature process water, resulting in low heat exchange efficiency and poor cooling effect. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a highly efficient and energy-saving chemical process cooling water circulation device.

[0006] To achieve this objective, the present invention adopts the following technical solution: a high-efficiency and energy-saving chemical process cooling water circulation device, comprising a mounting frame, a liquid storage component fixedly installed on the bottom inner wall of the mounting frame, the liquid storage component comprising a liquid storage tank fixedly installed on the bottom inner wall of the mounting frame, a cooler fixedly installed on the side wall of the liquid storage tank, an injection port and a drain port fixedly connected to the side wall of the liquid storage tank, and a primary heat exchange component and a secondary heat exchange component fixedly installed on the top of the mounting frame, wherein the primary heat exchange component, the secondary heat exchange component and the liquid storage component are interconnected.

[0007] Preferably, the primary heat exchange assembly includes a heat exchanger fixedly installed on the top of the mounting frame, the inlet of the heat exchanger being connected to the inlet pipe of high-temperature process water, and the outlet of the heat exchanger being connected to the secondary heat exchange assembly.

[0008] Preferably, a water pump is fixedly installed on the top of the mounting frame. The input end of the water pump is connected to the side wall of the liquid storage tank, and the output end of the water pump is connected to the liquid inlet of the heat exchanger. A drain pipe is fixedly connected to the liquid outlet of the heat exchanger. The bottom end of the drain pipe penetrates the top wall of the mounting frame and is connected to the top of the liquid storage tank.

[0009] Preferably, the secondary heat exchange assembly includes a heat exchange tank fixedly installed on the top of the mounting frame. A spiral heat exchange tube is fixedly installed inside the heat exchange tank. A water guide pipe is fixedly connected to the top end of the spiral heat exchange tube. The end of the water guide pipe away from the spiral heat exchange tube passes through the side wall of the heat exchange tank and is connected to the outlet of the heat exchanger. A water outlet pipe is fixedly connected to the bottom end of the spiral heat exchange tube. The end of the water outlet pipe away from the spiral heat exchange tube passes through the side wall of the heat exchange tank and extends to the outside of the heat exchange tank.

[0010] Preferably, multiple nozzles are uniformly fixedly installed on the top inner wall of the heat exchange tank, and a second water pump is fixedly installed on the top of the mounting frame. The input end and output end of the second water pump are respectively connected to the liquid storage tank and the multiple nozzles.

[0011] Preferably, a second drain pipe is fixedly inserted into the bottom of the mounting frame, and the bottom end of the second drain pipe penetrates the top wall of the mounting frame and is connected to the top of the storage tank.

[0012] Preferably, a fan is fixedly fitted on the inner ring of the top wall of the heat exchange tank.

[0013] The beneficial effects of this invention are as follows: When using this device, the inlet pipe of the high-temperature process water is connected to the inlet of the heat exchanger. Pump one is started to extract coolant from the storage tank and inject it into the heat exchanger through the inlet. Heat exchange is achieved using the temperature difference between the process water and the coolant, thus initially cooling the high-temperature process water. The initially cooled process water then enters the spiral heat exchange tube through a guide pipe. Pump two is started to extract coolant from the storage tank and spray it onto the spiral heat exchange tube through multiple nozzles, further cooling the process water flowing within the spiral heat exchange tube and increasing the cooling effect. A fan is started to forcibly introduce external air, increasing the airflow speed. This airflow carries away the heat released during water evaporation on the spiral heat exchange tube, thereby accelerating the cooling process. Through these features, the device can improve heat exchange efficiency through a two-stage heat exchange system, thereby increasing the cooling effect on the high-temperature process water.

A liquid storage component 2 is fixedly installed on the bottom inner wall of the mounting frame 1. The liquid storage component 2 includes a liquid storage tank 21 fixedly installed on the bottom inner wall of the mounting frame 1. A cooler 22 is fixedly installed on the side wall of the liquid storage tank 21.

Through these arrangements, the heat exchanger 31 provides preliminary cooling to the high-temperature process water. Furthermore, a thermoelectric power generation module can be installed on the side wall of the heat exchanger 31. Utilizing the principle of thermoelectric power generation, the temperature difference between the high-temperature process water and the coolant is converted into electrical energy.
