The water hammer preventing system can effectively eradicate the formation of water hammer of the steam heat supply pipe network, ensures the long-term safe operation of the heat supply network, can recycle condensed water in a centralized manner, save resources, reduces the thermal pollution and unsafe factors caused by in-situ emission of the condensed water, and can realize the full-automatic operation.

Description

Steam heat distribution pipe network water impact preventing system

Technical field

The utility model belongs to steam heat distribution pipe network conveying technology field, and the utility model especially relates to a kind of steam heat distribution pipe network water impact preventing system.

Background technology

Steam is in heat distribution pipe network course of conveying, because variations in temperature produces a certain amount of condensed water, reach when a certain amount of and can result in blockage and produce water attack when condensed water is gathered in the lower of thermal pipe or ascent stage, being created in heating network operation of water attack is hard to guard against, once and generation causes great destruction to the safety of heating network operation, so, how to prevent that steam heat supply network from producing water attack is in heating network operation an one also very scabrous difficult problem always urgently to be resolved hurrily.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, thereby provides a kind of water attack that can effectively prevent steam heat distribution pipe network to form the steam heat distribution pipe network water impact preventing system that water attack destroys heat supply network of stopping.

The technical scheme providing according to the utility model, described steam heat distribution pipe network water impact preventing system, comprise the first high liquid level sensor, the first low liquid level sensor, bag catchments, electric dredging devices water valve, water receiver, the second high liquid level sensor, heat-exchanger pump and the second low liquid level sensor, be fixed with at the low spot of steam heat solenoid or the lower wall of pipeline rising portion the bag that catchments, catchment bag delivery port and the water inlet of water receiver between be connected with drain pipe, electric dredging devices water valve is installed on drain pipe, the delivery port of water receiver with join by the water inlet of hot water inlet pipe and heat-exchanger pump, the delivery port of heat-exchanger pump is by hot water drainpipe access Recovery of the hot water station, the first high liquid level sensor and the first low liquid level sensor are installed in the steam heat solenoid of the side of wrapping that catchments, and the first high liquid level sensor and the first low liquid level sensor all join by holding wire and electric dredging devices water valve, the second high liquid level sensor and the second low liquid level sensor are installed in water receiver, and the second high liquid level sensor and the second low liquid level sensor all join by holding wire and heat-exchanger pump.

The water attack that the utility model can be stopped steam heat distribution pipe network effectively forms, ensure the long period safe operation of heat supply network, the utility model energy centralized recovery condensed water, economize on resources, reduce condensed water and discharge on the spot thermal pollution and the unsafe factor of generation, and the utility model can be realized full-automatic operation.

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is described in further detail.

This steam heat distribution pipe network water impact preventing system, comprise the first high liquid level sensor 1, the first low liquid level sensor 2, bag 3 catchments, electric dredging devices water valve 5, water receiver 6, the second high liquid level sensor 7, heat-exchanger pump 8 and the second low liquid level sensor 10, be fixed with at the low spot of steam heat solenoid 9 or the lower wall of pipeline rising portion the bag 3 that catchments, between bag 3 delivery port and the water inlet of water receiver 6, be connected with drain pipe 4 catchmenting, electric dredging devices water valve 5 is installed on drain pipe 4, the delivery port of water receiver 6 with join by the water inlet of hot water inlet pipe and heat-exchanger pump 8, the delivery port of heat-exchanger pump 8 is by hot water drainpipe access Recovery of the hot water station, in steam heat solenoid 9 above the bag 3 that catchments, the first high liquid level sensor 1 being installed all joins by holding wire and electric dredging devices water valve 5 with the high liquid level sensor 1 of the first low liquid level sensor 2, the first and the first low liquid level sensor 2, the second high liquid level sensor 7 is installed in water receiver 6 all to join by holding wire and heat-exchanger pump 8 with the high liquid level sensor 7 of the second low liquid level sensor 10, the second and the second low liquid level sensor 10.

Steam is in steam heat solenoid 9 is carried, when the excessive paramount water level point of the condensed water producing, touch the first high liquid level sensor 1 of high water level point, this first high liquid level sensor 1 sends signal to controller, controller is opened electronic electric dredging devices water valve 5 automatically, and condensed water is discharged in water receiver 6 by drain pipe 4, and liquid level sensor is also sent to heating network control center signal simultaneously, on LED display, show that full heat supply network may produce the situation of water attack, grasp full heating network operation safety.When the condensed water in steam heat solenoid 9 drops to low water level point, the low liquid level sensor 2 of the first low liquid level sensor 2, the first that touches low water level point sends signal to controller, closes electronic electric dredging devices water valve 5.Like this, at each low spot of steam heat solenoid 9 or pipeline rising portion (the hydrophobic place of operation need be set), this device is all installed, just can be effectively stopped the gathering of condensed water and the water attack that produces, ensure the operation of heat distribution pipe network energy long-term safety.

The excessive paramount water level point of condensate water level in water receiver 6, touch the second high liquid level sensor 7 of high water level point, the second high liquid level sensor 7 sends signal to controller, start heat-exchanger pump 8, condensed water is delivered to Recovery of the hot water station (unconditionally reclaim condensed water herein, electric dredging devices water valve 5 just can directly discharge) by hot water inlet pipe.When the condensate water level in water receiver 6 drops to low water level point, the low liquid level sensor 10 of the second low liquid level sensor 10, the second that touches low water level point sends signal to controller, closes down heat-exchanger pump 8, back and forth automatic cycle, ensures that each low spot of steam heat distribution pipe network can safe transport steam.
