Abstract
The invention discloses a novel U-shaped pipe gas water seal. The water seal comprises a water seal body U-shaped pipe, a condensate inlet pipe is arranged at the upper end of the water seal body U-shaped pipe, a condensate discharge pipe is disposed at the tail end of the water seal body U-shaped pipe, control valves are correspondingly arranged on the water seal body U-shaped pipe, the condensate inlet pipe and the condensate discharge pipe respectively, the condensate inlet pipe is connected with a circulating ammonia water pipe on one side of an upper pipe of the control valve, the condensate inlet pipe is connected with a steam pipe on one side of a lower pipe of the control valve, a water seal blow-down pipe is arranged at the bottom of the U-shaped portion of the water seal body U-shaped pipe, and a control valve is arranged on the water seal blow-down pipe. According to the novel U-shaped pipe gas water seal, circulating ammonia water is used for replacing steam for heat supply and insulation, and the design of a sealing structure is used structurally, so that emission of polluting and combustible gas is reduced effectively, and obvious effects on reducing environmental pollution and achieving energy saving and emission reduction are provided.
Description
Technical field
The present invention relates to a kind of water seal for coal gas, particularly a kind of Novel U-shaped pipe water seal for coal gas.
Background technique
Can continue in coke-stove gas conveyance conduit and the facility condensed fluid that tar, naphthalene, water etc. mix to occur, if untimely discharge can increase the coal gas transporting resistance, affect the equipment operation, destroy whole production when serious stable.
For the problem that occurs in the above-mentioned explained hereafter, general method is in coal gas conveying facility fixed point water seal for coal gas to be set at present, collect so serially and discharge condensed fluid, ensure the stable operation of gas transportation system, but common water seal needs a large amount of steam insulations, can produce a large amount of sewage like this, and common water seal for coal gas is after operation a period of time, because tar, dregs deposit in a large number in the water seal, the water seal emptying of just need in time stopping is processed.In addition, common water seal for coal gas is the equipment of open type, unavoidably has contaminativity and inflammable gas effluxes, not only can be to environment, and have inflammable and explosive danger.
Just because of the existing problem of above-mentioned common water seal for coal gas, to develop and a kind ofly novel can satisfy the explained hereafter requirement, the water seal for coal gas that can reach again energy-saving and emission-reduction becomes present problem demanding prompt solution.
Summary of the invention
Technical problem solved by the invention has provided a kind of Novel U-shaped pipe water seal for coal gas, and this invention utilizes cyclic ammonia water to replace steam to realize insulation, effectively reduces the discharging of harmful gas and sewage, thereby has realized the dual purpose of safety and environmental protection and energy-saving and emission-reduction.
For solving the problems of the technologies described above, a kind of Novel U-shaped pipe water seal for coal gas of the present invention, it is characterized in that, comprise water seal main body " U " type pipe, the upper end of described water seal main body " U " type pipe is provided with the condensed fluid inlet tube, end is provided with the outer comb of condensed fluid, described water seal main body " U " type pipe, the condensed fluid inlet tube, on the outer comb of condensed fluid respectively correspondence be provided with control valve, described condensed fluid inlet tube connects a side of the upper pipe of control valve and establishes the cyclic ammonia water pipeline, described condensed fluid inlet tube connects a side of the lower pipeline of control valve and establishes steam line, the bottom of the U-shaped portion position of described water seal main body " U " type pipe is provided with the water seal blow-down pipe, and described water seal blow-down pipe is provided with control valve.
On described cyclic ammonia water pipeline and the steam line respectively correspondence control valve is set.
The invention has the beneficial effects as follows:
1. the present invention utilizes cycling hot aqueous ammonia to replace steam to carry out heat supply insulation, realized water seal for coal gas without steam insulation, reduce the consumption of steam.
2. encapsulation of the present invention is better, and is excessive without gas, reduced contaminativity and inflammable gas effluxes, and effectively avoided the pollution of environment, also more is conducive to carry out on-the-spot fire operation simultaneously, so that on-the-spot fire operation is more safe and reliable.
3. the present invention installs and changes simplely, and operating process does not affect the normal operation of rough gas transporting system, and engineering work load is little, invests lowly, has preferably economic benefit and social benefit.
Description of drawings
Fig. 1 is structural drawing of the present invention;
Fig. 2 is the structural representation when installing and using;
Among the figure: 1 water seal main body " U " type pipe, 11U type position, 2 condensed fluid inlet tubes, 21 upper pipe, 22 lower pipeline, the outer comb of 3 condensed fluids, 4 control valves, 5 cyclic ammonia water pipelines, 6 steam lines, 7 water seal blow-down pipes, 8 gas transportation systems, 9 condensed fluid collection ponds.
Embodiment
As shown in Figure 1, a kind of Novel U-shaped pipe water seal for coal gas of the present invention, it comprises water seal main body " U " type pipe 1, the upper end of described water seal main body " U " type pipe 1 is provided with condensed fluid inlet tube 2, end is provided with the outer comb 3 of condensed fluid, on described water seal main body " U " type pipe 1, condensed fluid inlet tube 2, the outer comb 3 of condensed fluid respectively correspondence be provided with control valve 4.
The side that described condensed fluid inlet tube 2 connects the upper pipe 21 of control valve 4 is established cyclic ammonia water pipeline 5, pass into cycling hot ammoniacal liquor in the cyclic ammonia water pipeline 5, the temperature of cycling hot ammoniacal liquor remains on more than 75, can play so on the one hand the effect of water seal insulation, the effect that also can play on the other hand flushing water seal main body " U " type pipe 1, prevents from stopping up water seal main body " U " type pipe 1.
The side that described condensed fluid inlet tube 2 connects the lower pipeline 22 of control valve 4 is established steam line 6, can realize blocking pipe is cleaned fast when passing into steam in steam line 6.
The bottom of the U-shaped portion position 11 of described water seal main body " U " type pipe 1 is provided with water seal blow-down pipe 7, and described water seal blow-down pipe 7 is provided with control valve 4.Purpose of design is to be convenient to the dregs of water seal main body " U " type pipe 1 interior part remnants are discharged like this.
