Abstract
A deaerator of low-level heat power consists of degassing tower and water box. It is featured as setting air inlet pipe, water inlet pipe and air exhaust pipe on degassing tower; connecting one spare water pump and one on-service water pump to bottom of degassing tower; setting rotary diaphragm, packing and reboiling pipe net in degassing tower; and arranging self-control overflow unit of liquid level on water box.
Description
Technical field
The present invention relates to a kind of low level, heating power deaerator, mainly can be used for supporting with steam boiler.
Background technology
At present, the used oxygen-eliminating device of steam boiler is high-order thermal deaerator, comprises oxygen-eliminating device body and water pump, and described oxygen-eliminating device body is made of degassing tower that is interconnected and deoxygenation water tank, described degassing tower is provided with steam inlet pipe, water inlet pipe and direct blast pipe, is respectively applied for admission, water inlet and exhaust.The defective of air suspended type oxygen-eliminating device is that blast pipe directly is communicated with atmosphere outside, part steam in the degassing tower is directly entered atmosphere, cause the energy and water resource waste, and because the pressure in the water tank is low, pressure head is little before causing pump, forms the cavitation to water pump easily.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of low level, heating power deaerator, this low level, heating power deaerator helps reducing the waste of heat energy and water resource, and helps reducing the cavitation to water pump.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of low level, heating power deaerator, comprise the oxygen-eliminating device body that constitutes by degassing tower and water tank, and described degassing tower is provided with steam inlet pipe, water inlet pipe and blast pipe, and described blast pipe connects surge tank.
The invention has the beneficial effects as follows: owing on the degassing tower blast pipe, be provided with surge tank, under the normality exhaust valve of surge tank is closed, not external in line steam, the steam of input forms certain pressure gradually in surge tank and oxygen-eliminating device body, promoted the heating of steam to soft water, make most steam heats be exchanged for deaerated water and enter the circulatory system, improved utilization rate water resource in the steam and heat energy; Simultaneously owing to improved the pressure in the water tank, make the draining water pump of oxygen-eliminating device obtain sufficiently high dynamic head, satisfied the requirement of the anti-net positive suction head of water pump, avoided the cavitation of high-temperature water to water pump, oxygen-eliminating device can be placed on low level thus, reduced the civil engineering cost, shortened installation period, the management intuitive and convenient.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of low level, heating power deaerator comprises the oxygen-eliminating device body that is made of degassing tower 3 and water tank 9, and described degassing tower is provided with steam inlet pipe 10, water inlet pipe 4 and blast pipe 2, and described blast pipe connects surge tank 1.
Described blast pipe is provided with valve 11, and this valve can be often to open electrically-controlled valve.Under normal conditions, the steam in the degassing tower directly enters surge tank by its blast pipe, and the drain tap of surge tank is closed, and steam is outwards discharging not, forms pressure thus in surge tank and degassing tower.When pressure reaches certain value, close the exhaust valve of degassing tower, open oxygen and on-condensible gas in the drain tap discharging surge tank of surge tank, close the drain tap of surge tank then, open the exhaust valve of degassing tower, enter normality.
Described surge tank is provided with surge tank blast pipe 12, and described surge tank blast pipe is provided with valve 13, and this valve constitutes the drain tap of described surge tank, and can adopt normally closed electrically-controlled valve.
Described normally closed electrically-controlled valve and Chang Kai electrically-controlled valve can be provided with pressure sensor or timing controller (for example time relay), described pressure sensor is used for gathering the pressure signal of described surge tank, and described timing controller is used to produce the timing signal of control magnetic valve.When the pressure in the surge tank or time reach default discharge value, control described normally closed electrically-controlled valve and open, often open electrically-controlled valve and close, oxygen and on-condensible gas in the surge tank are discharged; When the pressure in the surge tank is reduced to default normality value or drain time when finishing, make normally closed electrically-controlled valve and Chang Kai electrically-controlled valve be returned to corresponding closure or opening.Described pressure sensor, each electrically-controlled valve and mounting means separately and interconnect mode and all can adopt prior art.
Described degassing tower bottom can connect boiler feed pump (or claim oxygen-eliminating device draining pump) 8, is used for the deaerated water of water tank is sent into feed water system of boiler pipeline 6, and the quantity of described water pump can be two or more, one be equipped with usefulness or one be equipped with many with or be equipped with many usefulness more.
Described deoxygenation water tank directly is associated in up and down with described boiler feed pump, need not the 5-16 rice discrepancy in elevation under the prior art.
Described water tank can be provided with automatic control of liquid level overflow mechanism 5, is used for carrying out when liquid level is extraordinary automatic overflow.Described automatic control of liquid level overflow mechanism and can adopt prior art with the connected mode of water tank.
Can be provided with rotary diaphragm, structured packing and the pipe network that seethes with excitement again in the described degassing tower, carry out three grades of deoxygenations, to improve deaerating effect.
Described each electrically-controlled valve, each water pump can also be provided with setting and the Artificial Control that electrical control cubicles is controlled parameter, and described electrical control cubicles can adopt prior art.
Because each equipment (degassing tower, surge tank, water pump etc.) in the utility model adopts pipeline to connect, under the constant situation that maintains the connection, the concrete installation site of each equipment does not exert an influence to enforcement of the present utility model, can specifically be provided with according to field conditions, for example the base of surge tank or support can equally be installed on the ground with described oxygen-eliminating device body base 7.
The utility model can be provided with auxiliary equipment such as various instrument, valve as required.
