Detailed description of the invention
As shown in Figure 1, a kind of individual well sledge dress heated by natural gas throttling arrangement, the heating furnace 2, the chimney 1 that comprise sledge seat 28 and be fixed on sledge seat, also comprise the Imported gas pipeline 8 be fixed on sledge seat, described Imported gas pipeline 8 is successively after the first heating plate group 6, choke valve 11, second heating plate group 7, choke valve 11, be connected with gas external transport pipeline 9, a branch is connected with return line 29 through gate valve 30 simultaneously;
After return line 29 and reverse pumping gas inlet line 10 merge, be connected with vertical separator 12, gate valve 30, stabilizator 16, pneumatic control case 18 successively, while stabilizator before gate valve also in parallel with gate valve, first group of preheat coil, 13, second group of preheat coil 14; The thermometer 15 that described pneumatic control case 18 is also other with heating furnace and temperature controller 17 are connected;
Out two pipelines from pneumatic control case 18, one through needle-valve 20, extinguish protector 22 and be connected with the female nozzles 21 being positioned at heating furnace, another is connected through stop valve 19, burner 23 and the main nozzles 24 that are positioned at heating furnace.
Heating furnace is fixedly mounted on sledge seat 28, is provided with chimney 1, is provided with explosion proof door below chimney on the left of heating furnace 2, and heating furnace 2 top is provided with drain 3, water supplement port 4 and manhole 5.First added water by water supplement port 4 pairs of inside heating furnace, in sledge, then pass into fuel gas igniting, the water of inside heating furnace is heated.
Fuel gas uses on-the-spot reverse pumping gas; heating throttling skid-mounted device is entered from reverse pumping gas inlet line 10; fuel gas enters after in sledge; be introduced into vertical separator 12; pneumatic control case 18 is entered again after stabilizator 16 pressure regulation; arrive female nozzles 21 and main nozzles 22 by female fiery burning line and main fiery burning line afterwards, female fiery burning line is provided with needle-valve 20 and extinguishes protector 22, and main fiery burning line is provided with stop valve 19 and burner 23.Burner 23 is negative-pressure ejecting formula burner, does not need electricity consumption and has anti-storm design.
When in-furnace temperature reaches field requirement, gas well defeated natural gas in sledge can be opened, natural gas enters after in sledge from Imported gas pipeline 8, be introduced into the first heating plate group 6 and carry out one-level heating, then after choke valve 11 carries out one-level throttling, enter the second heating plate group 7 again carry out secondary heating, defeated from gas external transport pipeline 9 after carrying out two-step throttle step-down afterwards again.
As shown in Figure 1 and Figure 2; after passing into reverse pumping gas in sledge; first open startup valve 26; burning torch is reached female nozzles 21 place; slowly the needle-valve 20 on female fiery burning line is opened again; female fire can be lighted; after female pyrogene merits and demerits are lighted; extinguishing protector above female nozzles is due to the valve automatically opening pneumatic operated valve 27 in pneumatic control case that is heated; now startup valve 26 cuts out; fuel gas can continue to carry in stove by pneumatic operated valve 27, as long as the stop valve 19 then opened on main fiery burning line can light main fire, namely burner drops into normal operation.
When there are abnormal conditions, as female flame extinguishes, the extinguishing protector on female fiery burning line can automatically be closed valve and pressure signal is delivered to pneumatic control case 18 by female fiery burning line, and pneumatic operated valve 27 can cut out automatically, stops transfer the fuel gas in stove.
Heating furnace 2 front is provided with thermometer 15 and temperature controller 17, and is connected with pneumatic control case 18, carries out temperature setting to temperature controller 17.Pneumatic control case 18 comprises two pneumatic operated valves, 27, two pneumatic operated valves 27 valve 25 in parallel for subsequent use and startup valve 26 respectively of series connection.Valve 25 for subsequent use, startup valve 26 are all gate valves.When device normally runs, when the bath temperature in heating furnace 2 reaches more than setting value, temperature controller 17 can pass the signal along to pneumatic operated valve 27, and pneumatic operated valve 27 can turn down valve automatically, and main fire is extinguished, when the bath temperature of heating furnace 2 is reduced to below setting value, temperature controller 17 can pass the signal along to pneumatic operated valve 27, and pneumatic operated valve 27 can open valve automatically, and main fire is rekindled heat the water of heating furnace 2, so repeatedly, round-the-clock operatorless control can be realized.
Can according to actual needs, do to optimize further or improve to above-mentioned a kind of individual well sledge dress heated by natural gas throttling arrangement.
As shown in Figure 1, natural gas is outer defeated after adding the two-step heating throttling of individual well sledge dress heated by natural gas throttling arrangement, while defeated outward, the gate valve 30 can opened on return line 29 makes a part of gas enter burning line to use as fuel gas, natural gas mixture is generally because well head carrys out gas, liquid is with in gas, when use on-the-spot from air feed as fuel gas time, need to be introduced into vertical separator 12 to be separated, again through first group of preheat coil 13 and the preheating of second group of preheat coil 14, and then enter heating furnace, so can solve and use scene from the problem of air feed as frozen block easy during fuel gas.
