Mechanical heat exchange device with automatic water saving function

Abstract

The invention provides a mechanical heat exchange device with an automatic water saving function. The mechanical heat exchange device comprises a heat exchange device and a valve. The valve comprises a self-operated temperature controller, an automatic pulse stream flushing device and a stopper which are mounted in the valve. The self-operated temperature controller comprises a temperature bulb, a valve rod and a sluice valve plate. The automatic pulse stream flushing device comprises a vane wheel. The vane wheel is connected with a stopping plate through a connecting rod. The stopping plate is of a movable structure. The tangential direction of the vane wheel is the water flow direction of a water inlet. The heat exchange device comprises a shell, a heat exchange tube in the shell and a tube plate used for positioning the heat exchange tube. Fluid in a tube pass of the heat exchange device enters upwards and rushes out downwards. The mechanical heat exchange device is simple in structure, water flow can be effectively and automatically controlled according to the temperature of circulating water, and pulse water flow is used for flushing so as to avoid scaling of pipelines; the heat exchanger structure is used for reuse of energy, and thus, cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of water-saving devices for heat exchangers, in particular to a mechanical automatic water-saving heat-exchange device used in petrochemical plants and others that uses circulating water and requires automatic regulation and heat exchange. Background technique [0002] Heat exchange processes exist widely in petroleum and chemical production processes, such as equipment cooling, process medium cooling, and waste heat recovery, etc., and heat exchange equipment and various adjustment systems are necessary conditions to ensure the smooth progress of heat exchange processes. In the production process of petroleum and chemical products, circulating water is mainly used to cool various high-temperature process media. Since the cooling water temperature fluctuates greatly due to the influence of the external environment, the maximum temperature difference can reach about 30 degrees Celsius. If the cooling water fl...

AI Technical Summary

Problems solved by technology

The existing self-operated temperature control devices on the market are relatively expensive, have poor adaptability, cannot be widely used in the automatic regulation of circulating water, and do not have the function of preventing the structure from scouring

At the same time, the existing self-operated regulating valve only plays the role of regulating the flow, and the cut-off of the water flow and the removal of the scale are two other devices. Moreover, after the hot fluid in the pipeline is discharged through the valve, a large amount of energy is wasted. , which seriously damages the economic benefits of industrial production
