Water hammer shock wave pulsation heat exchange device applied to ship water waste heat recovery system

Abstract

The invention discloses a water hammer shock wave impulse heat exchange device applied to a ship water waste heat recovery system. The device comprises a plate heat exchanger; for one way of the plate heat exchanger, heat produced by a diesel engine cylinder sleeve water heat source is exchanged by the plate heat exchanger, circulating heat exchanging in the plate heat exchanger is realized through a first water pump, for the other way of the plate heat exchanger, a cooling medium is driven by a centrifugal water pump to flow through a flow adjusting valve and a shock valve on a main loop to enter the plate heat exchanger for heat absorbing, a three-way valve is arranged between the flow adjusting valve and the shock valve, one port of the three-way valve is connected with a spring check valve, the spring check valve is located in an energy storage tank, the energy storage tank is connected with the main loop through a branch pipeline, and heat removing equipment for cooling the heated cooling medium is arranged on the main loop. Impulses are produced in a main pipeline, the pulsatory cooling medium beats the inner wall of the plate heat exchanger, and the device has the advantages that the waste heat utilization efficiency is high, the size of the heat exchanger is small and the device is not prone to scaling.

Description

technical field [0001] The invention relates to a water hammer shock wave pulsation heat exchange device applied to a ship water waste heat recovery system, belonging to the field of waste heat recovery. Background technique [0002] In recent years, with the strengthened requirements of IMO for ship Energy Efficiency Design Index (EDDI), the issue of energy saving of marine equipment has been paid more and more attention. In recent years, the heat transfer enhancement and anti-fouling issues of marine heat exchange equipment have attracted more and more attention. At present, the main direction of ship waste heat utilization is: the waste heat of exhaust gas of main and auxiliary engines and the waste heat of cylinder liner cooling water. Most of the waste heat of the exhaust gas is utilized by the exhaust gas turbine and the exhaust gas boiler of the engine, while the heat of the jacket water is taken away by the seawater in the central cooler. Some waste heat utilizatio...

Problems solved by technology

However, due to the need to transport fluid through motors and frequency-regulated pipeline pumps, electric energy is required, and energy consumption is high

Traditional pulsation generators generally use electromagnetic valves or reciprocating pumps, but these pulsation methods are active enhanced heat transfer technologies, which require additional energy consumption and are limited in practical applications
