Abstract
The utility model discloses a water sealing negative-pressure explosion-proof pressure relief device for a straw gasifying furnace. The water sealing negative-pressure explosion-proof pressure relief device comprises a straw gasifying furnace, wherein a hearth is formed in the straw gasifying furnace; a grate is arranged in the hearth for partitioning the hearth into an upper part and a lower part; the upper part is taken as a combustion chamber; the lower part is taken as an ash collecting chamber; the ash collecting chamber is connected with a pressure relief pipe; the pressure relief pipe is connected with a pressure relief water tank; water is filled into the pressure relief water tank; and the outlet of the pressure relief pipe extends under the water surface in the water tank, and is sealed with water. The water sealing negative-pressure explosion-proof pressure relief device is simple in structure, can be installed at one time and can work continuously by ensuring the water level height, does not require maintenance or manual operation, and is safe and reliable.
Description
Technical field
The utility model relates to a kind of stalk gasifier water seal negative pressure explosion-proof relief device.
Background technology
Methods such as rubber sheet or spring pressure cover plate are generally adopted in the explosion-proof decompression of existing stalk gasifier, and when pressure reach a certain height, the rubber plate or surpass spring pressure and back down cover plate of rising was brokenly laid down detonation pressure.
Existing explosion-proof relief is accomplished after spring pressure backs down cover plate at the rubber plate or surpass of rising brokenly, promptly is after pressure reach a certain height, to carry out pressure release, stores certain strength impact power, thereby has hidden danger.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; A kind of stalk gasifier water seal negative pressure explosion-proof relief device is provided, and it is simple in structure, and the highest safety stage height can be realized one-step installation, non-stop run; Need not maintain and manual operation, safe and reliable.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of stalk gasifier water seal negative pressure explosion-proof relief device; Comprising stalk gasifier, is burner hearth in the said stalk gasifier, is provided with fire grate in the burner hearth burner hearth is divided into upper and lower two portions; Top is divided into the combustion chamber, and the bottom is divided into dust collection chamber; Said dust collection chamber is connected with relief tube, and said relief tube connects the pressure release water tank, is filled with water in the said pressure release water tank, and water seal is carried out by water in the underwater that the outlet of said relief tube is stretched in the water tank.
Said relief tube and pressure release water tank are 6, are uniformly distributed in the periphery of stalk gasifier, and water seal is carried out by water in the underwater that the outlet of each relief tube is all stretched in the water tank, and 6 adjacent 6 water tanks that are interconnected in twos, make of pressure release water tank form as one.
Said pressure release water tank is connected with water tank connecting pipe.
Said fire grate below is provided with air-breathing balanced umbrella, and air-breathing balanced umbrella below is provided with air suction pipe, and said air suction pipe inlet mouth is arranged at air-breathing balanced umbrella below, and stalk gasifier is stretched out in the air suction pipe air outlet.
Said air-breathing balanced umbrella constitutes a umbrella-shaped structure by two balancing disks.
After the said water seal negative pressure of the utility model explosion-proof relief device absorbs the detonation certain pressure by negative pressure; Absorb certain pressure, draining highly generally at 100～150mm by water secondary in the relief tube again, very little to detonation pressure release resistance, can directly detonation gas be drained like this.
The utility model water seal negative pressure explosion-proof relief device has been realized the surging force that zero-pressure drainage detonation produces fully through negative pressure venting of dust explosion and draining, and is safe and reliable.
The utility model is simple in structure, and the highest safety stage height can be realized one-step installation, non-stop run, need not maintain and manual operation, and is safe and reliable.
