Domestic hot water supply device for factory and operation method

Abstract

The invention belongs to the technical field of mechanical engineering, and particularly relates to a domestic hot water supply device for a factory and an operation method. The domestic hot water supply device comprises a container, a heat charging device and a water homogenizing device; the container is provided with a steam pipe, a steam inlet pipe, a water inlet pipe, a water outlet pipe and a tap water pipe; the steam pipe is connected with the steam inlet pipe, the steam inlet pipe is connected with the heat charging device, and the steam pipe is provided with a first cut-off control valve; one end of the water outlet pipe is connected with the bottom of the container, the other end of the water outlet pipe is connected with a water tank, and the water tank is connected with a tail end water using unit; the water outlet pipe is provided with a second cut-off control valve; the water inlet pipe is connected with the water homogenizing device and enables steam condensation water to be conveyed to the water homogenizing device, and the tap water pipe is connected with the water inlet pipe and provided with a third cut-off control valve; and the container is provided with a temperature controller for controlling the water temperature in the container. By means of the domestic hot water supply device, the steam condensation water can be effectively used, tap water can be heated through steam when supplying of the condensation water is insufficient, two methods are combined, and the domestic hot water supply device saves energy and is convenient.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and relates to a water supply device, in particular to a domestic hot water supply device for factories and an operation method. Background technique [0002] Steam is an important energy source in industrial production. Steam has a high enthalpy per unit mass and is easy to control. Therefore, steam is mostly used as a heat source in many industrial productions such as chemical plants and food factories. The thermal energy of steam is composed of sensible heat and latent heat. The general heat exchange process only utilizes the latent heat and a small amount of sensible heat of steam. After the steam releases latent heat and a small amount of sensible heat, it becomes high-temperature condensed water. [0003] The steam in the steam pipeline produces condensed water due to the heat loss of the pipeline. If the condensed water at the bottom is not removed in time, it will flow with...
