Abstract
The utility model relates to an isolating device for a blowing gas recovery valve. The isolating device for the blowing gas recovery valve comprises the blowing gas recovery valve. The blowing gas recovery valve is connected with a blowing gas recovery header pipe; the blowing gas recovery header pipe is connected with a blowing gas waste heat centralized recovery device; a water seal for connecting the blowing gas recovery valve with the blowing gas recovery header pipe is arranged between the outlet of the blowing gas recovery valve and the blowing gas recovery header pipe; and the water seal is provided with a water adding valve, an overflow valve and a drainage blowoff valve. According to the technical scheme disclosed by the utility model, through arranging the water seal between the blowing gas recovery valve and the blowing gas recovery header pipe, when a furnace needs to be shut down for overhauling, the water seal and the water adding valve are opened, and a blowing gas recovery system overhauled after the furnace is shut down is effectively isolated from other gas production systems by utilizing water in the water seal, so that blowing gas generated by other gas production systems cannot enter a furnace body to be overhauled and the safety of overhauling personnel is ensured.
Description
Technical field
The utility model relates to a kind of disrupter, relates to a kind of disrupter that is used for the blowing air recovery valve of gas furnace specifically.
Background technology
The static bed gas making operation is a raw material with coal or Jiao, adopts the atmosphere intermission gas-made technology to produce semi-water gas and water-gas, supplies synthetic ammonia and the production of methyl alcohol system to use gas.In the production process of coal gas, gas furnace in a working cycle, be divided into blowing, on blow, blow down, blow on the secondary, air blows off five stages.Get into from the gas furnace bottom at blowing stage air; The blowing air that produces in the stove is come out from furnace roof; Get into tornado dust collector through last air flue; Blowing air after the dedusting goes the blowing air waste heat to concentrate the retrieving arrangement recovery waste heat through reclaiming house steward, and generally each gas furnace is provided with a blowing air recovery valve respectively, is just getting into blowing air recovery house steward through the blowing air after the tornado dust collector dedusting again through the blowing air recovery valve; Though blowing air is being carried out dedusting through process cyclone dust removal before the blowing air recovery valve; But wherein still carry secretly a certain amount of and the carry-over certain granules degree, the trim of the valve port that will wear and tear unavoidably, its abrasion loss is directly proportional with the speed of passing through of blowing air; Because the blowing air recovery valve is frequently closed for a long time, be easy to distortion simultaneously under 350 ℃ of temperature.Above-mentioned two kinds of reasons cause the sealing valve port degradation; There is certain drawback: the one, because sealing property is bad; The blowing air recovery valve can leak up coal gas and following steam blowing; Cause unnecessary leakage loss, the lighter sacrifices waste heat and concentrate to reclaim due benefit, and is heavy then jeopardize and keep the safety in production even lead to explosion hazard; The 2nd, because the shared blowing air waste heat of each gas furnace is concentrated retrieving arrangement; So when a certain gas furnace shutdown maintenance wherein; The blowing air waste heat concentrates retrieving arrangement still to need work, and the decline of blowing air recovery valve sealing property is in waste heat string to the body of heater that is overhauling that the gas furnace that can cause producing produces; The maintainer is caused the human injury, and promptly blowing air recovery system and gas furnace production system can not be isolated completely effectively.
The utility model content
The purpose of the utility model provides a kind of disrupter of blowing air recovery valve, and this disrupter is guaranteed the isolation of blowing air recovery system and gas furnace production system when gas furnace stops and overhaul, and safety performance is high.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: comprise the blowing air recovery valve; The blowing air recovery valve reclaims house steward with blowing air and links to each other; Blowing air reclaims house steward and concentrates retrieving arrangement to link to each other with the blowing air waste heat, and the outlet of described blowing air recovery valve is reclaimed between the house steward with blowing air and is provided with the water seal that is connected both, is respectively equipped with priming valve, surplus valve and the wash water valve that discharges water in the described water seal.
The water seal of the utility model is the water seal of U type, comprises the body that is the U type, and the body two ends of U type water seal link to each other with the outlet and the blowing air recovery house steward of blowing air recovery valve respectively.
The water seal of the utility model is the van-type water seal, comprises envelope and first, second pipeline, and an end of first, second pipeline stretches in the envelope, and the other end of first, second pipeline links to each other with the outlet and the blowing air recovery house steward of blowing air recovery valve respectively.
Also be provided with the clean-up port in the van-type water seal of the utility model.
The outlet of the surplus valve of the utility model links to each other with overflow pipe.
Can know by technique scheme; The utility model is through being provided with water seal between blowing air recovery valve and blowing air recovery house steward; When the needs shutdown maintenance, open the water seal priming valve, utilize the water in the water seal that blowing air recovery system and other gas prodn system of shutdown maintenance effectively isolated; The blowing air that other gas prodn system is produced can not get into the body of heater of Awaiting Overhaul, and maintainer's safety is protected.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Like Fig. 1, a kind of blowing air recovery valve disrupter shown in Figure 2; Comprise blowing air recovery valve 1; Blowing air recovery valve 1 reclaims house steward 2 with blowing air and links to each other, and blowing air reclaims house steward 2 and concentrates retrieving arrangement 3 to link to each other with the blowing air waste heat, and the outlet of blowing air recovery valve 1 is reclaimed between the house steward 2 with blowing air and is provided with the water seal that is connected both; Be respectively equipped with priming valve 4, surplus valve 5 and the wash water valve 6 that discharges water in the water seal; The outlet of surplus valve 5 links to each other with overflow pipe, and regular switch when the wash water valve 6 of discharging water is flat is to remove the condensation ponding in the water seal.
Embodiment one:
As shown in Figure 1, water seal is U type water seal 7, comprises the body 71 that is the U type, and the body two ends of U type water seal 7 link to each other with the outlet and the blowing air recovery house steward 2 of blowing air recovery valve 1 respectively, are respectively equipped with priming valve 4, surplus valve 5 and the wash water valve 6 that discharges water in the U type water seal 7.
Embodiment two:
