Abstract
The present invention combines the steam boiler thermal deaerator self-body, electric automatic control, level automatic control fluid flow device and water pump together and makes them into an electromechanical equipment and provides its related technique. It is characterized by that said equipment is arranged at lower position, its deaerization water tank is equipped with level automatic control overflow device and reboiling gridiron, on the upper deaerating tube a deaerating automatic control valve is added.
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
Existing steam boiler oxygen-eliminating device is high-order thermal deaerator (referring to Fig. 1), it comprises oxygen-eliminating device body and water pump 8, described oxygen-eliminating device body mainly is made of degassing tower 2 and water tank 1, described degassing tower is provided with steam inlet pipe 5, water inlet pipe 3 and direct gland steam exhauster 4, prevent the condensed water in high temperature cavitation damage owing to generally believe the water tank in the oxygen-eliminating device body for a long time to the big more water pump that helps more of the vertical discrepancy in elevation of water pump, therefore the oxygen-eliminating device body is arranged on a high position, make the water tank of oxygen-eliminating device body form elevated tank, its setting height(from bottom) can be 7-14m, the downpipe 7 that respective length is set between water tank and the water pump connects, water outlet 6 in the water tank enters water pump by this pipeline, discharges through pumping line 9.The defective of this high-order thermal deaerator is that construction investment is big, hoisting difficulty is big, the construction time is long and still has certain pump cavitation problem.
This high-order thermal deaerator employing prevents that the technological means of cavitation from being the pump cavitation under solving dynamically with the hydrostatic head under static, belongs to static theoretical in theory.But be based on the product that this static theory designs, head exists during clean attitude, static pressure head Lock-out when pump is moving, any one setting pressure table at downpipe, survey its force value and be all negative pressure, this is to change the acceleration that high speed is rotated and water falls naturally by water pump per minute 2950 to cause, relies on elevated tank can't eliminate the existence of this negative pressure, therefore also just can't eliminate the cavitation of water pump.
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 relies on dynamic head to prevent pump cavitation, has not only reduced cavitation effectively, and has greatly reduced construction investment and hoisting difficulty.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of low level, heating power deaerator, comprise oxygen-eliminating device body and water pump, described oxygen-eliminating device body mainly is made of degassing tower and water tank, also be provided be used for deaerated water heating again boiling in length and breadth to steam pipe system, described water pump is positioned at oxygen-eliminating device body below, connects with described water tank, and described degassing tower is provided with steam inlet pipe, water inlet pipe and gland steam exhauster, described gland steam exhauster is provided with autocontrol valve, is connected with the automatic control of liquid level overflow mechanism on the described water tank.
Because the present invention is provided with autocontrol valve on gland steam exhauster, do not add and can close automatically when steam does not need deoxygenation yet not advancing demineralized water, not only energy-conservation but also guaranteed the stability of tank pressure; Because water tank is provided with the automatic control of liquid level overflow mechanism, has replaced the multilevel water seal of existing high-order oxygen-eliminating device, service pressure is by bringing up to 0.02-0.6Mpa below the 0.02Mpa under the prior art; Owing to kept the pressure of steam in the water tank to liquid level, make water pump obtain enough dynamic heads, satisfied the requirement of the anti-net positive suction head of water pump, and the setting height(from bottom) of integral device reduces ground from 7-14m, not only save a large amount of civil engineering cost and lifting cost, make become simple and direct is installed, maintenance management has also made things convenient for.
Description of drawings
Fig. 1 is the structural representation of the high-order thermal deaerator under the prior art;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Referring to Fig. 2, low level, heating power deaerator provided by the invention comprises oxygen-eliminating device body and water pump 8, described oxygen-eliminating device body mainly is made of degassing tower 2 and water tank 1, described degassing tower is provided with steam inlet pipe 5, water inlet pipe 3 and gland steam exhauster 10, and described gland steam exhauster is provided with autocontrol valve 11, is connected with automatic control of liquid level overflow mechanism 13 on the described water tank, be provided with the space 12 that holds steam and water in the water tank, described water pump is provided with outlet pipe 9, is positioned at oxygen-eliminating device body below, connects with described water tank.
The present invention can be provided with vertical and horizontal steam pipe system, is used for substituting the single tube under the prior art, carries out deaerated water heating boiling again, and this mode of heating has been avoided the single tube heating produces under the prior art heating inequality and water hammer.
The present invention can be provided with rotary diaphragm, structured packing and the net that seethes with excitement again, carries out three grades of deoxygenations, makes deaerating effect be better than high-order thermal deaerator under the prior art.
Claims (2)
1. low level, heating power deaerator, comprise oxygen-eliminating device body and water pump, it is characterized in that described oxygen-eliminating device body mainly is made of degassing tower and water tank, also be provided be used for deaerated water heating again boiling in length and breadth to steam pipe system, described water pump is positioned at oxygen-eliminating device body below, connects with described water tank, and described degassing tower is provided with steam inlet pipe, water inlet pipe and gland steam exhauster, described gland steam exhauster is provided with autocontrol valve, is connected with the automatic control of liquid level overflow mechanism on the described water tank.
