Abstract
A uniflow steam boiler with level control function has a water gauge outside the boiler. Said water gauge is communicated downward to the water-discharge drain tube of boiler and upward to the linking tube of safety valve, and has an internal sensor composed of upper, middle and lower electrode rods. Said sensor is connected to controller connected with water pump. Its advantages is easy control of water level in boiler.
Description
The present invention is the improvement to existing direct-flow steam boiler.
Existing direct-flow steam boiler because of its design feature, the water level meter is not installed, so water level is unclear, and is difficult to control, makes the boiler operatiopn instability, and load is difficult to regulate.Water entrained by steam is serious when water level in the boiler is too high, and quality of steam is difficult to control.
The objective of the invention is to design a kind of direct-flow steam boiler with water level control function, it should easier control the water level of boiler, makes boiler operatiopn stable, and can regulate load.It also should make water level in the boiler keep normal, to guarantee quality of steam.
The present invention includes direct-flow steam boiler 1, water level meter 2, be provided with water level meter 2 in the outside of direct-flow steam boiler 1, the below of water level meter 2 is connected with the blow-off pipe 4 that discharges water of direct-flow steam boiler 1 by water pipe 3, and the top of water level meter 2 is connected with the safety valve connecting pipe 5 of direct-flow steam boiler 1 by water pipe 3.
The present invention installs water level meter 2 between the vapor space of direct-flow steam boiler 1 and hydrospace, the water level that it can be controlled in the boiler is no more than peak level, be implemented in peak level top and arrange net gas section (or superheat section), force boiler to produce steam like this, and improved the steam quality of boiler, made stable operation of the boiler.It can also regulate load, makes water level in the boiler keep normal.
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the structural representation of embodiment two.
Embodiment one: present embodiment is made up of direct-flow steam boiler 1, water level meter 2.Direct-flow steam boiler 1 inside is provided with inside and outside coil pipe 6, is provided with burner 7, vapor outlet port valve 8 and safety valve 9 above the direct-flow steam boiler 1.The blow-off pipe 4 that discharges water is positioned at the below of direct-flow steam boiler 1 and is connected with inside and outside coil pipe 6.Be provided with water level meter 2 in the outside of direct-flow steam boiler 1, the below of water level meter 2 is connected with the blow-off pipe 4 that discharges water by water pipe 3, and the top of water level meter 2 is connected with the adapter 5 of safety valve 9 by water pipe 3.The top of the water pipe 3 above water level meter 2 is provided with Pressure gauge 14 and pressure controller 15.
Embodiment two: what present embodiment and embodiment one were different is to be provided with sensor 10 in the inside of water level meter 2, sensor 10 is made up of high water level electrode rod 11, mid water levels electrode bar 12 and low water level electrode rod 13, sensor 10 is connected with controller 16 through lead, controller 16 is connected with water pump 17 through lead, and water pump 17 is connected on the feed pipe 18 of direct-flow steam boiler 1.Other composition is identical with embodiment one with annexation.
The high, medium and low level electrode rod of sensor 10 passes to controller 16 with peak level, mid water levels, lowest water level signal, and control the work of water pump 17 by controller 16, when water level reached highest order, water pump quit work, when water level reached lowest order, water pump was started working.It makes boiler realize automatic control.
