Hot water circulation converter

Abstract

The invention discloses a hot-water circulation convertor which works between a waste heat recovery device and a hot-water heating pipe network. The hot-water circulation convertor structurally comprises an electrical valve group, a first water storage chamber, a second water storage chamber and a one-way valve group. The first water storage chamber and the second water storage chamber are identical in structure. Under the control of the electrical valve group, the working sequence of the hot-water circulation convertor is that heating hot water stored in the first water storage chamber is supplied from the bottom to the hot-water heating pipe network through a one-way valve. Low-temperature water returns through the hot-water heating pipe network and flows into the first water storage chamber from the top through an electrical valve. The low-temperature return water stored in the second water storage chamber is supplemented into the waste heat recovery device from the top through the electrical valve. The heating hot water from the waste heat recovery device flows from the bottom into the second water storage chamber through the one-way valve. After set time, the first water storage chamber and the second water storage chamber respectively performs the process opposite to the process.

Description

technical field [0001] The invention relates to heat supply technology, in particular to a hot water circulation converter. Background technique [0002] In my country's industrial and agricultural production, a large amount of waste hot water at 50-100°C is discharged. Because the waste hot water contains impurities, its heat energy is difficult to recycle, and it is all discarded. Among them, the slag flushing water of iron and steel enterprises is a typical example. [0003] my country is already a big country in steel production, and the annual output of steel accounts for 40% of the world's total output. Whether it is steelmaking or ironmaking, a large amount of slag will be produced. Slag is produced along with iron and steel. It is a by-product of iron and steel smelting, and it is also the basic condition for a series of important metallurgical reactions. It directly participates in the physical and chemical reactions and mass and heat transfer processes of iron an...

Problems solved by technology

This situation brings about a problem: the heating circulating water channel in the intermittent heat exchanger cannot be part of the closed regional hot water heating pipe network, that is, the two cannot be directly connected

[0017] 1. The heat transfer capacity of this partition wall heat exchanger is huge and the cost is high;

[0018] 2. The heat transfer temperature difference of the partition wall heat exchanger makes the output heat lower the heating temperature
