Based on the above, the present invention provides a kind of mine water residual heat direct heating system, the system is straight using mine water residual heat
It connects and is used for wellhead anti-freezing, system is practical, efficient, it is only necessary to consume a small amount of electric energy, not generate the discharge of any waste, operating cost
It is low.
This system includes water system and wind system two parts.
Water system is divided into heat source side and for hot side, and interior heat source lateral line is mine water, for being to avoid in hot side circulation line
Equipment scaling influences service life of equipment, and intermediate heat transfer is used for using softened water.Heat source side is by mine water feed cistern, latent
Dirty pump, quartz filter, plate heat exchanger, mine water back pool composition.High-temperature mine water is conveyed through submersible sewage pump in feed cistern
To quartz filter, plate heat exchanger is entered after filtering, is transferred heat to for hot side recirculated water, mine water cooling heel row is extremely
Back pool.Water system is for hot side by heating cycle water pump, well head heating unit inner-finned-tube heat exchanger, constant pressure water compensation apparatus, soft
Change water tank composition, the intermediate circulating water after heating is delivered to well head heating unit by heating cycle water pump, for wellhead anti-freezing, drop
It is heated, moved in circles again by plate heat exchanger after temperature.Water system is equipped with softening water tank and constant pressure water compensation apparatus, pipeline for hot side
When interior pressure is reduced to below setting value, system automatic water supplement maintains circulating pressure to stablize.
Wind system is mainly made of centrifugal fan, air outlet in Electric air valve, filter screen, well head heating unit.Around
Environment fresh air enters in well head heating unit through Electric air valve, filter screen, is exchanged heat by finned tube under centrifugal fan effect
Device exchanges heat with water system for hot side recirculated water, is sent after heating through air outlet to well head, meets wellhead anti-freezing demand.
Water system is for installing electric control valve, well head heating unit root on hot side well head heating unit circulating water outlet pipeline
According to the variation of ambient temperature, real-time controlling opening of valve adjusts wind pushing temperature, and then it is relatively permanent that well head is kept to mix air temperature
It is fixed.
Under well head heating unit closed state, unit monitoring fresh air environment temperature, when new air temperature exchanges heat less than finned tube
After device inner coil pipe deicing requirements temperature, unit opens anti-freezing pattern, and Electric air valve aperture is adjusted to zero, and cut-out environment is entered the wind, together
When dynamoelectric water valve open completely, keep finned tube exchanger in circulating water line it is unimpeded, prevent well head heat unit internal coil
Bursting by freezing.
