Description

TECHNICAL FIELD

[0001] The utility model relates to static pressure kettle technical field, concretely is a static pressure kettle waste heat recovery device. BACKGROUND

[0002] Static pressure kettle, also known as static high pressure vessel or isostatic pressure vessel, is a kind of high pressure vessel equipment. Its working principle is to use high-pressure liquid or gas as pressure transmission medium to apply high pressure in all directions to the object to be treated. The container body is usually made of high-strength, corrosion-resistant material to ensure that it can withstand high pressure and high temperature environment. Static pressure kettle also has the advantages of compact structure, simple operation, safety and reliability. In order to improve energy utilization efficiency, reduce production cost and reduce environmental pollution, static pressure kettle needs to use waste heat recovery device.

[0003] Common static pressure kettle waste heat recovery device is usually composed of bottom plate, support structure, static pressure kettle, reaction box, waste heat recovery system, filtration system and other auxiliary components. The bottom plate is used to support and fix other components. The support frame is used to fix the static pressure kettle. The static pressure kettle is provided with a reaction box inside for high-pressure reaction or treatment. The waste heat recovery system is used to transfer the collected waste heat to the filter tank for further treatment. The filtration system is used to filter and purify the transferred waste heat to remove impurities and particulate matter. Other auxiliary components include access doors, pipes, valves, etc.

[0004] Traditional static pressure kettle generates heat during the reaction process and discharges the generated heat outward, which not only causes a large amount of heat loss, but also causes thermal pollution to the environment, affecting the surrounding ecosystem and biological community. To solve the above problems, some static pressure kettles are equipped with pump body, filtering mechanism and storage tank. The pump body first transports the hot gas generated in the static pressure kettle to the inside of the storage tank, the hot gas is filtered by the filtering mechanism to remove impurities in the gas, and then the hot gas is transported to the inside of the storage tank for storage and discharged outward during use. However, this method cannot handle the toxic substances in the form of gas in the hot gas discharged from the static pressure kettle, which not only reduces the waste heat recovery effect, but also increases the difficulty of recycling. Therefore, a static pressure kettle waste heat recovery device is proposed. UTILITY MODEL CONTENTS
