A coal gas water closing device is connected in parallel on the prior system which adopts a an electrical control butterfly valve to realize the blast furnace gas releasing; when the electrical control butterfly valve is closed abnormally, and a main pipe is in a high pressure state, the coal gas releasing is realized by applying the principle of coal gas water closing puncture. The blast furnace gas automatic releasing device has simple application principle and low cost, and is practical and is easy to be processed and manufactured; besides, the device has the advantages of simple maintenance and safety and reliability.
Description
Technical field
The utility model relates to the automatic bleeding device of a kind of blast furnace gas of smelter.
Background technology
At present, Iron and Steel Enterprises in China blast furnace gas residue bleeding device, what the overwhelming majority adopted is the set(ting)value of motorized adjustment butterfly valve according to the main pipe pressure parameter, controls automatically and realizes diffusing.The patent of the at present domestic relevant automatic bleeding device of blast furnace gas is devoted to the Control Study and the improvement of gas bleeding valve mostly.But how the control of no matter diffusing valve improves, and still has the following shortcoming that can't overcome based on this automatic bleeding device of blast furnace gas that diffuses valve: (1) can not have a power failure by answering system.When system blackout and the coal gas user produces when stopping suddenly, cause main pipe pressure to raise rapidly, accident to leak the coal gas takes place, the crisis life security because the big large time delay of reaction causes blast furnace gas hydathode along the line to puncture easily in the manual operation bleeding device.(2) the motorized adjustment butterfly valve easily breaks down.When system produces normally, and the motorized adjustment butterfly valve overhauls it when breaking down, and obviously can influence to produce or cause main pipe pressure to raise.
The utility model content
Technical problem to be solved in the utility model provides the automatic bleeding device of a kind of blast furnace gas, and when blast furnace system production is normal, and the electronic releasing device of blast furnace gas occurs when unusual, can make still that blast furnace gas is safe and reliable to be diffused.
For solving the problems of the technologies described above, the utility model proposes following technical scheme: comprise motorized adjustment butterfly valve, bleeder, it is characterized in that, also comprise inlet pipe, water-sealed cylinder, water service pipe, water-freeing arrangement, described water-sealed cylinder connects described water service pipe and water-freeing arrangement respectively, one end of described inlet pipe is connected on the person in charge between blast furnace gas source of the gas and the described motorized adjustment butterfly valve, and the other end inserts in the water body in the described water-sealed cylinder, and said structure forms the blast furnace gas water seal.
As further improvement, described water-sealed cylinder inner route clapboard is divided into forward and backward two Room, and described dividing plate height is higher than the height of water body, and the dividing plate bottom has communicating aperture, and described inlet pipe is inserted in the water body of cup.Cup plays the water seal effect, and exhaust and shock absorption are played in back chamber, with the impact of buffering high pressure, high velocity air.
Further optimize, the chamber is connected on the person in charge between described motorized adjustment butterfly valve and the bleeder by vapor pipe behind the described water-sealed cylinder.
Preferably, described water service pipe comprises a U type pipe.
Same preferred, described water-freeing arrangement comprises upflow tube, the 2nd U type pipe, water shoot, gas-liquid shunting bleeder, described upflow tube one end connects described water-sealed cylinder, the other end connects described the 2nd U type pipe, one end of described the 2nd U type pipe connects described gas-liquid shunting bleeder, the other end connects described water shoot, and Open Side Down for described water shoot, and described gas-liquid shunting bleeder opening upwards.
The utility model is by the utility model in parallel in the system that realizes blast furnace gas at original employing motorized adjustment butterfly valve and diffuse, when abnormal conditions are that the motorized adjustment butterfly valve cuts out, and be responsible for when the ultra-high voltage state occurring, the principle of using coal gas water seal puncture realizes diffusing of coal gas, applied principle is simple, practicality is processed, is made easily, and cost is low; Has simple and convenient operation and maintenance simultaneously, safe and reliable advantage.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Fig. 1 is the automatic bleeding device structure principle chart of blast furnace gas of the present utility model.
Embodiment
As shown in Figure 1, one end of inlet pipe 12 is connected on the person in charge 1 between blast furnace gas source of the gas and the motorized adjustment butterfly valve 2, in the water body in the other end insertion water-sealed cylinder 5, water-sealed cylinder 5 connects water service pipe 10 by feedwater valve 9, water service pipe 10 comprises the first U-shaped pipe 14, keep storing the water of certain altitude in the water-sealed cylinder 5, form the blast furnace gas water seal.Water-sealed cylinder 5 is divided into cup 16 and two Room 17, back by dividing plate 8, the height of dividing plate 8 is higher than the height of water body, about 200mm place, dividing plate 8 bottoms opens a communicating aperture 4, inlet pipe 12 is inserted in the water body of cup 16, cup 16 plays the water seal effect, 17 exhausts in back chamber and shock absorption are with the impact of buffering high pressure, high velocity air.Chamber 17 is connected on the person in charge between electric butterfly valve 2 and the bleeder 3 by vapor pipe 15 behind the water-sealed cylinder.Water-sealed cylinder 5 also connects by surplus valve 13 and connects upflow tube 18, the end that surplus valve 13 connects the second U-shaped pipe, 19, the second U-shaped pipes 19 connects gas-liquid shunting bleeder 6, and the other end connects water shoot 7, Open Side Down for water shoot 7, and gas-liquid shunting bleeder 6 openings upwards.Surplus valve shown in the figure 13 comprises A, B, three surplus valves that are installed in different heights of C, is responsible for the different needs of operating pressure size according to coal gas, regulate and definite water-sealed cylinder 5 in water seal height after, choose and open one of them.For example, main pipe pressure is less than 12000Pa during works better, and then the water seal height in the water-sealed cylinder 5 is 1200mm, if the B point of setting highly is 1200mm, so just selects to open the surplus valve 13 of B point position.
During ordinary production, be responsible for 1 ultra-high voltage that produces by regulating 2 controls of motorized adjustment butterfly valve.If motorized adjustment butterfly valve 2 is in closing condition, in the time of can not normally opening, blast furnace gas promptly enters water-sealed cylinder 5 by inlet pipe 12, and breaks through water seal and implement to diffuse, and main pipe pressure 1 promptly reduces, and prevents that the ultra-high voltage accident from appearring in the blast furnace gas person in charge thereby reach.
Should be noted that; the exemplary illustration that this embodiment is just done the utility model and do not limit its protection domain; those skilled in the art can also make the change of some unsubstantialities to the utility model; so long as the improvement of carrying out without creative work and to this patent, all within the protection domain of this patent.
