Abstract
The utility model discloses a deaerated water tank water seal device which comprises a water seal cylinder. The water seal cylinder is composed of an outer steel tube and an inner steel tube, wherein the inner steel tube is disposed inside the outer steel tube in a sleeved mode, a water seal volume is positioned between the inner steel tube and the outer steel tube, the top and the bottom of the outer steel tube are sealed, a pressure relief tube opening to the atmosphere is disposed above the side wall of the outer steel tube, the top of the outer steel tube of the water seal cylinder is provided with a desalting water pipe used for replenishing water for the water seal cylinder, the desalting water pipe is provided with a first valve, two ends of the inner steel tube are open, the top opening is connected with steam space above the deaerated water tank through a pipeline, and a second valve is placed on the pipeline. By the aid of the deaerated water tank water seal device, the spare pressure relief tube is arranged to guarantee pressure safety of the deaerated water tank when the water seal cylinder is in an isolated state, the valves are added between the deaerated water tank and the water seal cylinder to isolate the water seal cylinder and the deaerated water tank, and thereby the water seal cylinder can be smoothly filled with the water.
Description
Technical field
The relevant a kind of water seal arrangement of the utility model refers to a kind of deoxygenation water tank water seal arrangement that can fill water in the normal operating pressure scope of deoxygenation water tank especially.
Background technique
The atmosphere-type thermodynamic oxygen remover working pressure is 0.02MPa, and pressure maximum is 0.04MPa.Because the safety valve lowest set pressure is more than the 0.1MPa, thus can not use safety valve as pressure relief device, and serve as pressure relief device with the water seal cylinder.When the deaerator storage tank internal pressure rises to when the highest, the water seal arrangement inside and outside differential pressure is greater than water column pressure in the water seal arrangement, the carbonated drink pressure balance is destroyed in the water seal arrangement, water in the water seal arrangement is extruded discharge, steam drains into atmosphere continually by water seal arrangement in the deaerator storage tank, with the deaerator storage tank internal pressure normal value of releasing, guarantee that deaerator storage tank is not because of the superpressure explosion.
Because of after the deaerator storage tank superpressure breaks through water seal, almost anhydrous in the water seal arrangement, if under oxygen-eliminating device working pressure 0.02MPa to the water seal arrangement moisturizing, so then be to cover little water to be blown out by the steam of the inside at once, just can't normally seal water seal arrangement at all.Can only reduce at present the oxygen-eliminating device working pressure in the actual motion to 0MPa, then water in the water seal arrangement could be filled, slowly promote again oxygen-eliminating device pressure to working pressure.Yet the working pressure of reduction and recovery oxygen-eliminating device can cause full factory thermodynamic system changes in balance, affects boiler capacity and generator power output, and adjusting is got up difficult, has wasted operator's time and efforts.
The model utility content
In view of this, main purpose of the present utility model is to provide a kind of deoxygenation water tank water seal arrangement that can fill water in the normal operating pressure scope of oxygen-eliminating device.
For achieving the above object, the utility model provides a kind of deoxygenation water tank water seal arrangement, it includes the water seal cylinder, this water seal cylinder is comprised of outer layer pipe and the inner layer steel pipe that is sheathed in the outer layer pipe, be the volume of water seal between the inside and outside two-layer steel pipe, this outer layer pipe top and bottom sealing, this outer layer pipe sidewall top is provided with the relief tube that leads to atmosphere, the outer layer pipe top of this water seal cylinder is provided with the desalting pipe of supplementing water sealed tube water, this desalting pipe is provided with the first valve, this inner layer steel pipe both ends open, the open-topped place connects the air space of deoxygenation water tank top by a pipeline, and this pipeline is provided with the second valve.
Be provided with relief tube for subsequent use between described the second valve and the described deoxygenation water tank, on this relief tube for subsequent use the 3rd valve be installed.
The utility model arranges the second valve between deoxygenation water tank and water seal cylinder, be provided with relief tube for subsequent use between this second valve and the deoxygenation water tank, water seal in the water seal cylinder is because of deoxygenation water tank superpressure when destroyed, guaranteeing under the deoxygenation water tank pressure security, needn't reduce the oxygen-eliminating device working pressure, can will fill water in the water seal cylinder smoothly, allow water seal arrangement recover normal operation.
Description of drawings
Fig. 1 is the structural representation of the utility model deoxygenation water tank water seal arrangement.
Embodiment
For ease of structure of the present utility model and the effect that reaches are had further understanding, the existing preferred embodiment that develops simultaneously by reference to the accompanying drawings is described in detail as follows.
As shown in Figure 1, a kind of deoxygenation water tank water seal arrangement of the present utility model, it includes water seal cylinder 1, this water seal cylinder 1 is comprised of outer layer pipe 10 and the inner layer steel pipes 11 that are sheathed in the outer layer pipe 10, be the volume of water seal between the inside and outside two-layer steel pipe, outer layer pipe 10 tops and bottom sealing, outer layer pipe 10 sidewalls top is provided with the relief tube 2 that leads to atmosphere, outer layer pipe 10 tops of water seal cylinder 1 are provided with the desalting pipe 3 of supplementing water sealed tube 1 water, this desalting pipe 3 is provided with the first valve 4, inner layer steel pipe 11 both ends opens of water seal cylinder 1, the open-topped place connects the air space of deoxygenation water tank 8 tops by a pipeline, this pipeline is provided with the second valve 5, is provided with relief tube 6 for subsequent use between this second valve 5 and the deoxygenation water tank 8, and the 3rd valve 7 is installed on this relief tube for subsequent use.
As shown in the figure, during 8 normal operation of deoxygenation water tank, the second valve 5 is opened, the first valve 4 and the 3rd valve 7 are closed, water column static pressure in the water seal cylinder 1 equals the working pressure of deoxygenation water tank 8, by the water of water seal cylinder 1 deoxygenation water tank 8 and outside atmosphere is isolated, and keeps the normal operating pressure of deoxygenation water tank 8.When the pressure superpressure of deoxygenation water tank 8, water is extruded rising and passes through relief tube 2 discharges in the water seal cylinder 1, deoxygenation water tank 8 directly contacts with atmosphere with relief tube 2 by water seal cylinder 1, the pressure drop of deoxygenation water tank 8 is to normal value, the steam of constantly emerging in the relief tube 2, open first the 3rd valve 7 this moment, close again the second valve 5, relief tube 2 steam of no longer emerging, and then open the first valve 4 and replenish demineralized water by desalting pipe 3 in water seal cylinder 1 is until have water continuously till the outflow in the relief tube 2, close again the first valve 4, open the second valve 5, close at last the 3rd valve 7, water seal works again.
The utility model arranges the second valve between deoxygenation water tank and water seal cylinder, be provided with relief tube for subsequent use between this second valve and the deoxygenation water tank, water seal in the water seal cylinder is because of deoxygenation water tank superpressure when destroyed, guaranteeing under the deoxygenation water tank pressure security, needn't reduce the oxygen-eliminating device working pressure, can will fill water in the water seal cylinder smoothly, allow water seal arrangement recover normal operation.
The above is preferred embodiment of the present utility model only, is not be used to limiting protection domain of the present utility model.
