Background
The prior art comprises and has the structure that:
in a traditional steam-water heat exchange unit, a heat exchanger adopts a form of a primary desuperheater and a traditional plate heat exchanger or a form of a tubular heat exchanger, heat of a heat source is exchanged to a secondary side, and a medium on the secondary side circulates to a user side to send out heat under the action of a circulating water pump.
The prior art has the following defects: both of these forms of heat exchangers are inefficient; the primary desuperheater and the traditional plate heat exchanger are not suitable for high-temperature and high-pressure working conditions; the shell and tube heat exchanger occupies a large space.
SUMMERY OF THE UTILITY MODEL
In order to solve the heat exchange efficiency who improves heat exchanger group, the problem of the limitation that better solution one-level desuperheater + plate heat exchanger form was suitable for, the utility model provides an energy-saving soda heat exchanger group more saves steam, saves running cost and maintenance cost, can the above-mentioned weak point of effectual improvement.
The technical scheme adopted by the utility model for solving the technical problems is to provide an energy-saving steam-water heat exchanger unit, which comprises a spiral wound tubular heat exchanger, a secondary net circulating system, a water supplementing system, a primary steam system, a condensate water system and an electric control system; the steam inlet of the spiral wound tube type heat exchanger is connected to a primary steam system, the condensation outlet of the spiral wound tube type heat exchanger is connected to a condensate water system, the secondary water outlet and the secondary water inlet of the spiral wound tube type heat exchanger are respectively connected to a secondary net circulating system, and the secondary net circulating system is connected to a water supplementing system; and the electric control system is respectively connected to the secondary network circulating system, the water supplementing system and the primary steam system through signal lines.
Further, the spiral winding pipe type heat exchanger is connected with the secondary network circulating system, the water replenishing system, the primary steam system and the condensed water system through bolts.
Further, the shell of the spiral wound tube type heat exchanger is made of 304 stainless steel, and the heat exchange tube is made of 316L stainless steel.
Compared with the prior art, the beneficial effects of the utility model are that:
1. through changing the heat exchanger form, make full use of steam carries out heating heat recovery, improves the heat exchange efficiency of heat exchanger greatly. Under the same working condition and the same heating area requirement, the using amount of steam can be greatly reduced, and more energy is saved.
2. The shell of the spiral winding tube type heat exchanger is made of 304 stainless steel, the heat exchange tube is made of 316L stainless steel, the heat exchanger is integrally welded, the model selection design is carried out according to different working conditions, the spiral winding tube type heat exchanger is particularly suitable for high-temperature and high-pressure working conditions, the highest temperature resistance can reach 400 ℃, and the highest pressure can reach 4.0MPa (heating working condition).
3. Because the spiral wound tube type heat exchanger has a different structure from the common tube type heat exchanger, the heat exchange tube of the spiral wound tube type heat exchanger is in a spiral form, and under the condition of the same heat exchange area, the size of the spiral wound tube type heat exchanger is smaller, and the occupied space is small.
