Description
Technical field
The utility model relates to fixed-bed intermittent formula gas stove field, specifically a kind of intermittent coal gas stove Special water seal with safe insulating effect.
Background technique
The structure of original intermittent coal gas stove water seal as shown in Figure 1, comprise the coal gas inlet pipe being installed on Safety water seal body 1 top, the up gas pipe 2 communicated with coal gas inlet pipe and little dust collector 3, be communicated in the descending gas pipe 4 on little dust collector 3, the coal gas inlet pipe being positioned at Safety water seal body 1 top is in series with the first hydraulic seat plate valve 5, and coal gas inlet pipe is connected with Safety water seal body 1 inside by the coal gas Inserting Tube 6 of Safety water seal body 1 inside, Safety water seal body 1 side surface upper part is provided with relief valve 7, middle part is provided with the first priming valve 8, bottom is provided with drain valve 9, Safety water seal body 1 top is connected with gas main by 90 degree of coal gas bend pipes 10.
The main effect of this Safety water seal body 1 be for when shutdown maintenance adds water and coal gas system isolate, prevention coal gas flows backwards.And this Safety water seal body 1 is again the unique channel that separate unit gas stove is supplied gas to system simultaneously, the first hydraulic seat plate valve 5(DN700 hydraulic seat plate valve) play a part when blowing out to block coal gas, installation position is that side is entered the end and gone out.But in furnace shutting down process, if hydraulic system failure, the first hydraulic seat plate valve 5 runs out of steam, and the system pressure of gas main can make coal gas flow backwards its valve plate jack-up bottom the first hydraulic seat plate valve 5, and then initiation security incident, and Safety water seal body 1 can not replace blind plate.
Summary of the invention
The potential safety hazard that the utility model exists to solve current intermittent coal gas producer gas system, provides a kind of intermittent coal gas stove Special water seal with safe insulating effect.
The utility model is achieved through the following technical solutions: the intermittent coal gas stove Special water seal with safe insulating effect, comprise the coal gas inlet pipe being installed on Safety water seal body top, be series at the first hydraulic seat plate valve on the coal gas inlet pipe at Safety water seal body top, be communicated with the coal gas Inserting Tube of coal gas inlet pipe and Safety water seal body inside, be installed on the drain valve of the first priming valve in the middle part of Safety water seal body side surface, bottom, be installed on 90 degree of coal gas bend pipes between Safety water seal body and gas main, relief valve
The 90 degree of coal gas bend pipes being positioned at Safety water seal body outlet port are in series with the second hydraulic seat plate valve.
During concrete use, the second hydraulic seat plate valve and gas making oil-way system are interlocked, and the start-stop stove button interlocking of this valve and DCS control system, this valve opening when gas stove runs, during normal production, this valve is in normal opening state, automatically closes during blowing out.When running into unexpected incidents (as post has a power failure or oil-way system fault) and causing blowing out, this valve is closed automatically, coal gas system and gas main can be made to completely cut off, coal gas refluence is avoided to cause the security incidents such as blast or fire, there is the space of slip spade simultaneously when overhauling after installing this valve additional, itself and coal gas system can be made thoroughly to completely cut off.
The intermittent coal gas stove Special water seal with safe insulating effect described in the utility model; utilize System interlocks; reach the effect of duplicate protection; in furnace shutting down process; effectively can completely cut off coal gas; avoid the phenomenon that coal gas flows backwards when post power failure or oil-way system fault, ensure that ability anti-risk in production run process.
Accompanying drawing explanation
Fig. 1 is the structural representation of original intermittent coal gas stove water seal.
Fig. 2 is the structural representation with the intermittent coal gas stove Special water seal of safe insulating effect described in the utility model.
In figure: 1-Safety water seal body, the up gas pipe of 2-, the little dust collector of 3-, the descending gas pipe of 4-, 5-first hydraulic seat plate valve, 6-coal gas Inserting Tube, 7-relief valve, 8-first priming valve, 9-drain valve, 10-90 degree coal gas bend pipe, 11-second hydraulic seat plate valve, 12-Ash valves, 13-second priming valve.
Embodiment
There is the intermittent coal gas stove Special water seal of safe insulating effect, comprise the coal gas inlet pipe being installed on Safety water seal body 1 top, be series at the first hydraulic seat plate valve 5 on the coal gas inlet pipe at Safety water seal body 1 top, be communicated with the coal gas Inserting Tube 6 of coal gas inlet pipe and Safety water seal body 1 inside, be installed on the drain valve 9 of the first priming valve 8 in the middle part of Safety water seal body 1 side, bottom, be installed on 90 degree of coal gas bend pipes 10 between Safety water seal body 1 and gas main, relief valve 7
The 90 degree of coal gas bend pipes 10 being positioned at Safety water seal body 1 outlet port are in series with the second hydraulic seat plate valve 11.
See Fig. 2, described relief valve 7 is installed on the coal gas inlet pipe between Safety water seal body 1 and the first hydraulic seat plate valve 5.Effectively can increase the height of water seal, flowing backwards for preventing coal gas serves the effect of dual fail-safe.
Further, Safety water seal body 1 side lower is provided with Ash valves 12.Mainly discharge the lime-ash be deposited in bottom Safety water seal body 1.In addition, before ash discharge, add appropriate circulating water by the first priming valve 8, the environmental pollution problem in ash discharge process can be avoided on the one hand, also a small amount of thin ash can be taken out of from Ash valves 12 on the other hand.After drained ash, then open the drain valve 12 of Safety water seal body 1 bottom, by emptying for its internal residual water rear closedown.During concrete enforcement, adopt the Ash valves of DN300 model.
In addition, between the inlet pipeline of the first priming valve 8 and 90 degree of coal gas bend pipes 10 between the second hydraulic seat plate valve 11 and gas main, the second priming valve 13 is installed.Main Function by remaining in the coal ash punching of 90 degree of coal gas bend pipes 10 to the bottom of Safety water seal body 1, then be discharged by Ash valves 12, can effectively avoid the coal ash at 90 degree of coal gas bend pipe 10 places to accumulate the phenomenon causing gas resistance to raise.During normal production, timing should be opened by this priming valve, rinse the coal ash that 90 degree of coal gas bend pipe 10 places accumulate.
During concrete enforcement, preferably original coal gas Inserting Tube 6 is shortened, extend the waiting time of coal gas in Safety water seal body 1, and its mouth of pipe is designed to the angle of 45 °, the larger particles that carries in coal gas such as slag, coal ash etc. can be made to be deposited in the bottom of Safety water seal body 1, enter in the gas pipe line before waste heat boiler from avoiding the large granular impurity that coal gas carries to a great extent, important function is served to reduction gas resistance.
Above-mentioned improved device, proves through running: when semi-water gas tolerance is constant, the gas resistance of gasification system reduces 5kPa, and separate unit stove gas forming amount adds 600 m
3/ h, System steam consumption reduces 5t/h, not only reduces feed coal consumption, decreases gas condensed water amount simultaneously, namely alleviates the environmental protection pressure of circulating water for gasification.
