Intermittent high-pressure steam heat recovery device

Abstract

The invention discloses an intermittent high-pressure steam heat recovery device, and belongs to the technical field of energy conservation. The device comprises a steam collection and heat exchange device, a buffer water tank and a circulating water system, wherein the steam collection and heat exchange device comprises a heat exchange tube, a guide plate, a spring and a flexible pipe; the spring pushes the guide plate to move up and down; four inlets and outlets are formed in the buffer water tank in all, and can be increased or reduced according to the service condition of hot water; and the circulating water system comprises an internal water cycle between the steam collection and heat exchange device and the buffer water tank and an external water cycle between the buffer water tank and tail end equipment. The intermittent high-pressure steam heat recovery device disclosed by the invention achieves effective and convenient recovery and utilization on intermittent steam; waste of heat is avoided; and the energy utilization rate is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and in particular relates to heat recovery and utilization in an industrial production process using intermittent high-temperature and high-pressure steam, such as using intermittent high-temperature and high-pressure steam to iron product clothing in the production process of a textile factory. Background technique [0002] Intermittent high-temperature and high-pressure steam refers to intermittently feeding high-temperature and high-pressure steam into the equipment in use for the equipment to complete a certain function. As a result, the steam discharged from the equipment after work has high heat content, but it is not continuous and is usually not recovered and utilized. [0003] In my country, high-temperature and high-pressure steam is widely used in the production process of the textile industry to iron product clothing. Among them, the widely used cloth ironing forming unit belon...

AI Technical Summary

Problems solved by technology

Due to the intermittent nature of the ironing work, the high-temperature and high-pressure steam fed into the equipment is intermittent. After the high-temperature and high-pressure steam is fed into the ironing machine, it is often discharged directly into the sewer or the environment without being reused.

The temperature of this part of the discharged steam is mostly above 100°C, which contains a large amount of heat energy that has not been recovered and utilized. Currently, there is no device that can effectively collect this energy on the market.
