Description
Technical field:
the utility model relates to a waste heat utilization system, in particular to a steam condensate waste heat recycling system.
The background technology is as follows:
the molecular sieve is an adsorption device frequently used in the field of coal chemical industry, and the principle is that the surface of the adsorbent is covered by the adsorbate after adsorption is carried out for a certain time through the adsorbent in the molecular sieve, so that the adsorption capacity is rapidly reduced, and the adsorbate is required to be desorbed at the moment, so that the adsorbent is regenerated. There are various regeneration methods, and there is a conventional heating regeneration method, in which a regenerated gas is heated by a steam heater and then fed into a molecular sieve, and the adsorbed substance is desorbed by increasing the temperature of the adsorbent. The condensate formed after the heat exchange and the temperature reduction of the steam in the steam heater is sent into a desalted water system for recycling. However, because the steam consumption of the steam heater is higher, the operation cost is increased, and more importantly, the condensate temperature of the steam heater is higher, so that the service life of the desalted water regeneration bed EDR is seriously influenced; and the temperature of the regenerated gas heated by the steam heater is low frequently, so that the molecular sieve cannot be thoroughly activated, and the molecular sieve is operated for a long time, so that the adsorption capacity of the molecular sieve is gradually reduced, and the service life of the molecular sieve is seriously influenced.
The utility model comprises the following steps:
in order to solve the problems, the utility model aims to provide a steam condensate waste heat recycling system.

the steam outlet of the steam source is communicated with the steam inlet of the steam heater through a pipeline, the condensate outlet of the steam heater is communicated with the condensate inlet of the steam condensate tank through a pipeline, the liquid outlet of the steam condensate tank is communicated with the heat medium inlet of the condensate heat exchanger through a pipeline, and the heat medium outlet of the condensate heat exchanger is communicated with the water inlet of the desalted water system through a pipeline.
Further, the top of the steam condensate tank is also provided with an air vent.
Further, a condensate pump is arranged on a pipeline for communicating the steam condensate tank and the condensate heat exchanger.
The utility model has the advantages that:
according to the utility model, the temperature of the regenerated gas of the molecular sieve can be increased by carrying out heat exchange and temperature rise on condensate generated after the regenerated gas is firstly subjected to heat exchange with the steam heater and then entering the steam heater for heating and temperature rise, so that the regenerated gas temperature reaches the temperature required by the activation of the molecular sieve, the molecular sieve is thoroughly activated, the maximum dynamic adsorption capacity of the molecular sieve is exerted, and the service life of the molecular sieve is prolonged; meanwhile, the steam consumption of the steam heater can be reduced by heat exchange and temperature rise twice, so that the purpose of saving energy consumption is realized; in addition, the condensate temperature can be reduced, so that desalted water system equipment is protected.
