Problems solved by technology

[0002] At present, in the process of oil production, it is necessary to use a large amount of high-temperature water vapor to heat various pipes, tanks and other equipment. After the heating operation is completed, the high-temperature steam is often condensed from a vapor state to a liquid, thereby producing a large amount of oil with a relatively high temperature. High-temperature condensed water, because these condensed waters contain a large amount of heat energy resources on the one hand, and on the other hand, water resources also need to be fully recycled. After performing one-stage or multi-stage heat exchange, it is reintroduced into the steam boiler, so as to achieve the purpose of recycling the condensed water itself and waste heat. However, in actual work, it is found that the comprehensive

Embodiment 1

[0019] Such as figure 1 A heat exchange process for comprehensive recovery of heat energy shown includes the following steps:

[0020] The first step is condensed water recovery. The condensed water produced after heating the pipelines, tank farms and other equipment is recovered through the collection tank. When recovering, according to the temperature of the condensed water, the condensed water with a temperature difference of 10°C is collected separately. cans for recycling;

[0021] In the second step, one-time filtration, the condensed water in each collection tank is passed through the filter device respectively, and the solid particle impurities in the condensed water are filtered;

[0022] The third step is softening, passing the filtered condensed water into the softening water device for softening treatment, and collecting and storing the softened condensed water through the softening tank again;

[0023] The fourth step is secondary filtration. The softened conden...

Embodiment 2

[0029] Such as figure 1 A heat exchange process for comprehensive recovery of heat energy shown includes the following steps:

[0030] The first step is condensed water recovery. The condensed water produced after heating the pipelines, tank farms and other equipment is recovered through the collection tank. When recovering, according to the temperature of the condensed water, the condensed water with a temperature difference of 20°C is collected separately. cans for recycling;

[0031] In the second step, one-time filtration, the condensed water in each collection tank is passed through the filter device respectively, and the solid particle impurities in the condensed water are filtered;

[0032] The third step is softening, passing the filtered condensed water into the softening water device for softening treatment, and collecting and storing the softened condensed water through the softening tank again;

Abstract

The invention provides a process for comprehensively recovering heat energy and exchanging heat. The process comprises five steps, namely, the step of recovering condensed water, the step of filtering for the first time, the step of softening, the step of filtering for the second time, and the step of reusing. The process is simple in steps, and convenient to operate and control; the comprehensive recycling rate of condensed water and condensed water afterheat can be effectively improved, and moreover, the quality of the condensed water can be effectively improved, thus the recycling efficiency and safety of the condensed water can be improved, and as a result, the purposes of reducing the comprehensive utilization rate of the energy of a heating system and reducing the risk of failure of the heating system due to water scale and other reasons can be achieved.
