Abstract
The invention discloses a drain water seal, and relates to improvement of drain water seal structures mainly for combustible gases, such as gas, marsh gas and the like, after dehumidification and dehydration. The invention provides a drain water seal which can prevent contaminations of condensate water from blocking the drain pipes. The drain water seal comprises a condensate pipe, wherein a primary drain pipe with a switch valve is arranged below the condensate pipe, a water seal pipe communicated with the air is arranged outside the primary drain pipe, and a secondary drain pipe is arranged above the water seal pipe.
Description
Technical field:
The present invention relates to a kind of improvement that is mainly used in the drain water seal structure after combustion gas field dehumidifying such as combustion gas such as gas, biogas are dewatered.
Background technique:
General combustion gas processing system, gaseous-pressure is lower than 100KPa, and the pressure head that is reflected at water is lower than 10 meters.In existing combustion gas processing system, generally be to need to discharge condensed water after the combustion gas dehumidifying of pressure is arranged, the method of draining generally adopts the method for float-ball type draining, also have and adopt the method for balance water seal to realize, the method of traditional float-ball type draining is unfavorable for discharging the condensed water that has solid particle polluter, granule foreign or obstruction weep hole are not gone out condensed water row; Weep hole is not closed completely, produces gas leakage, and cause security incident.The on-the-spot layout that is difficult for of balance water seal is restricted by site environment, has gas leakage when layout is unreasonable; Solid particle polluter stops up descending pipeline when long-time running, causes drain function to lose efficacy, but also can damage rear end equipment.
Summary of the invention:
The present invention is exactly at the problems referred to above, provides a kind of dirt of condensed water that prevents to stop up the drain water seal of waste pipe.
For achieving the above object, the present invention adopts following technological scheme, the present invention includes condensate pipe, its structure outline be the waste pipe that condensate pipe below is provided with switch valve, one time waste pipe is outside equipped with the water sealing (sealing water) pipe that communicates with atmosphere, and the top of water sealing (sealing water) pipe is provided with the secondary waste pipe.
Beneficial effect of the present invention:
1, the dirt that can prevent condensed water stops up waste pipe
The present invention can make the be discharged into water sealing (sealing water) pipe of the condensed water that contains solid particle polluter of condensate pipe through a waste pipe, when the water sealing (sealing water) pipe liquid level is higher than secondary waste pipe draining liquid level, condensed water is discharged water seal, because of the situation that does not have the valve opening and closing draining exists, the situation that particulate dirt is stopped up waste pipe will not take place;
2, simple in structure
The present invention mainly adopts pipe fitting and valve, and pipe fitting, valve all can purchase from market, easily makes, and easily applies universal.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of two condensate pipes.
Embodiment:
The present invention includes condensate pipe 1,3, waste pipes 3 of a waste pipe that condensate pipe 1 below is provided with switch valve 2 are outside equipped with the water sealing (sealing water) pipe 6 that communicates with atmosphere, and the top of water sealing (sealing water) pipe 6 is provided with secondary waste pipe 4.
Also can be provided with flush pipe 5 in the side of a waste pipe 3 with switch valve 2; Under switch valve 2 normalities of flush pipe 5 is closed condition.When needing to get rid of the solid particle polluter sediments of water sealing (sealing water) pipe 6 belows, open the switch valve 2 of flush pipe 5, meanwhile close the switch valve 2 of a waste pipe 3, have the water of the flush pipe 5 of pressure that the solid particle sediments is gone out, water sealing (sealing water) pipe 6 is had the flushing of pressure.
Water sealing (sealing water) pipe 6 can place underground, and general vertical depth is more than 1.5 times of fall head that gaseous-pressure is reflected at water.
During use, the condensed water that combustion gas is discharged after treatment, switch valve 2 (being opening state under the normality) through a waste pipe 3, one time waste pipe 3 is discharged in the water sealing (sealing water) pipe 6, when liquid level in the water sealing (sealing water) pipe 6 is higher than secondary waste pipe 4 draining liquid levels, condensed water is discharged from secondary waste pipe 4, is discharged to outer draining occasions such as gutter.
