Problems solved by technology
[0006] Insufficient utilization of condensed water waste heat. The existing condensed water recovery part adopts the form of plate heat exchanger. When the temperature of condensed water is higher than the return water temperature of the secondary network, the waste heat of condensed water can be recycled.
When the temperature of the condensed water is close to or lower than the return water temperature of the secondary network, the plate heat exchanger cannot use the waste heat of the condensed water

Embodiment 1
[0073] The heating renovation project of an industrial family area of a group company in Hubei, with a heating area of about 122,474m 2 , a total of 39 residential buildings, 1598 households. The original district heating system condensed water is directly discharged, and now an absorption heat pump is added to recover the waste heat of steam condensed water, which is used for district heating and reduces the steam consumption of the heating system.
[0074] The design parameters of the primary steam network are 1.3MPa(g), 300°C, and the operating parameters are: 0.6Mpa, 180°C;
[0075] The design temperature of the heating medium supply and return water of the secondary network is 75°C / 50°C, and the design pressure is 0.9MPa;
[0076] Residential heating area is about 122474m2 2 , the total heat load is about 7348kW.
[0077] A waste heat absorption heat pump is now added. The main heat exchanger of the system adopts a spiral wound tube heat exchanger. According to the...

The invention provides a novel steam condensate waste heat recovery system for heating. The system comprises a steam-water heat exchanger and an absorption heat pump unit, one side of the steam-waterheat exchanger is connected with a steam-liquid separator in parallel through a first steel pipe and a third steel pipe, and the other side of the steam-water heat exchanger is connected with a secondsteel pipe and a fourth steel pipe which are connected in parallel. By adopting an absorption heat pump for waste heat recovery of condensate water, the temperature of the condensate water can be reduced to 25 DEG C, the situation that conventional heat exchange can only reach the temperature close to 50 DEG C of a secondary net is broken through, and waste heat resources of the condensate waterare utilized to the maximum extent.
Description
technical field [0001] The invention relates to the field of heating and heat exchange, in particular to a novel heating steam condensate waste heat recovery system. Background technique [0002] Energy saving and emission reduction is an urgent problem to be solved in the current social development. The purpose of steam condensate waste heat utilization is to maximize the limited energy of steam, develop circular economy, improve energy utilization efficiency, reduce energy consumption, and reduce the emission of heat source heating pollutants. Effective protection of the environment. [0003] A large amount of condensed water is produced in the process of civil heating and heat exchange. Due to the instability of the outlet water temperature, only a small part of this condensed water is reused at present, and the rest is directly discharged into the municipal sewage pipe network, which is a great waste. In winter, it can often be seen near the heat exchange station of the...
