Abstract
The utility model discloses a sealing device of a gas producer fire detecting hole seat. The sealing device is characterized in that an annular water seal is arranged on the upper portion of the gas producer fire detecting hole seat, the annular water seal is provided with a water inlet and a water outlet, and a sealing cover arranged on the upper portion of a fire detecting hole performs sealing by contacting with an annular water seal groove. The sealing device is capable of tightly sealing coal gas leaked out due to abrasion of a sealed surface of a fire detecting hole plug, keeps no coal gas of a furnace surface, reduces occupational hazard and environmental pollution caused by coal gas leakage, and has the advantages of simple structure, small investment and fine effect. The sealing device has excellent reference and popularization values for coal gas sealing of all gas producer fire detecting holes and observation holes.
Description
Technical field
The utility model relates to a kind of tightness system of producer gas generator fire exploring hole seat.
Background technology
The producer gas generator fire detecting arrangement adopts steam to seal when visiting fire at present, then adopts the mechanical seal mode to seal in other period.Because the mechanical seal tightness is relatively poor, especially under the situation of sealing surface wear, sealing effectiveness is poorer, causes producer gas generator to be given birth to often normal, exists a large amount of coal gas to leak, and causes the operating environment gas concentration higher, easily causes personnel to poison.
The utility model content
In order to improve the producer gas generator operating environment, stop coal gas and leak from the producer gas generator fire exploring hole, reduce the gas concentration of operating surface, avoid acute and chronic poisoning of generation personnel and environmental pollution incident.The utility model provides a kind of principle of utilizing water seal coal gas to be carried out the tightness system of the producer gas generator fire exploring hole seat of tight seal.
The technical solution of the utility model is: on producer gas generator fire exploring hole seat top an annular water seal is set, annular water seal has water-in and water outlet, and fire exploring hole top has sealing cover to contact with annular seal-water tank to seal.
The utility model compared with prior art has following positively effect:
Can keep boiler face not have coal gas to the coal gas tight seal that leaks out because of fire exploring hole plug sealing surface wear, reduce the occupational hazards and the environmental pollution that cause because of gas leak.And this apparatus structure is simple, and less investment is effective.The utility model has good reference and promotional value to the coal gas sealing of all producer gas generator fire exploring holes, vision slit.
Description of drawings
Fig. 1 is the schematic diagram of sealing device (front view) of producer gas generator fire exploring hole seat of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Among the figure, 1-water-in, the water seal of 2-annular, 3-water outlet, 4-fire exploring hole mouth, 5-loop turn.
Embodiment
Producer gas generator is not high from gas pressure that fire exploring hole leaks when ordinary production, amount is little; According to water to the comparatively tight characteristics of air seal.On fire exploring hole top a h being set is 80mm, the annular water seal of φ 195 * φ 150mm, be used for the coal gas that sealing leak is come out, water-in and the water outlet (mode that connects with the connecting mode employing internal thread of external water pipe) of a φ=24mm are set at annular water seal h=91mm place, as shown in Figure 1, fire exploring hole top has sealing cover (adopt left-hand thread formula bell jar) to contact with annular seal-water tank to seal.Calculate and utilize water seal can seal up the coal gas of pressure below 0.89Pa.During ordinary production, keep in the water seal of fire exploring hole annular not lack of water by the external water source of the entery and delivery port on the fire exploring hole, to guarantee the sealing effectiveness of this fire exploring hole; When visiting fiery operation, form steam film by high pressure steam flow at high speed in the loop turn of fire exploring hole seat bottom, coal gas is sealed.
During ordinary production, there is a spy fire plug that coal gas is sealed for the first time, carries out secondary seal by left-hand thread formula bell jar and annular water seal at annular water seal 2 places at fire exploring hole mouth 4 places.When visiting fiery operation, when visiting fiery operation, form steam film by high pressure steam flow at high speed in the loop turn 5 of fire exploring hole seat bottom, coal gas is sealed.
