Abstract
The invention discloses a gas and water separating device for urea raw material gas, aiming at solving a problem of an existing urea producing raw material gas which is serious in CO2 gas waste in gas and water separation. The gas and water separating device comprises a gas and water separator (1), wherein a urea raw material gas inlet pipe (2), a CO2 gas exhaust pipe (3) and a separated water drainage port (4) are respectively arranged on the gas and water separator (1); a drainage pipe (6) is connected to the separated water drainage port (4); a reverse spraying valve (5) is arranged on the drainage pipe (6); water seal water (8) is arranged in a water seal container (9); a water outlet (7) of the drainage pipe (6) is arranged in the water seal water (8) in the water seal container (9); pressure on the water outlet (7) of the drainage pipe (6) is greater than that of urea raw material gas in the gas and water separator (1). The gas and water separating device can prevent waste of the raw material gas and enhance urea yield.
Description
Technical field
The present invention relates to a kind of gas and water separator, particularly a kind of gas and water separator of urea unstripped gas.
Background technology
When fertilizer plant produces urea, be by moisture CO
2gas falls to drench before compressor inlet separator, tends to cause CO in draining
2gas waste; And processing requirement wants interval discharge per half an hour once, adjust that to drench valve half-open by closing, there is the staff heavy and CO that works
2gas is wasted serious problem.
Summary of the invention
The invention provides a kind of urea unstripped gas gas and water separator, there is CO in the unstripped gas that has solved existing production urea in gas-water separation
2gas is wasted serious problem.
The present invention solves above technical problem by the following technical programs:
A unstripped gas gas and water separator, comprises air water separator, is respectively arranged with urea unstripped gas and enters tracheae, CO on air water separator
2gas outlet pipe and Separation of Water relief outlet, on Separation of Water relief outlet, be connected with water shoot, on water shoot, be provided with and drench valve, in water-sealed container, be provided with water seal water, the water outlet of water shoot is arranged in the water seal water arranging in water-sealed container, at the pressure of the water outlet of water shoot, is greater than the pressure of the urea unstripped gas in air water separator.
The pressure of the water outlet of water shoot is 20 kPas, and the pressure of the urea unstripped gas in air water separator is 13 kPas.
The isolated moisture of separator of the present invention is discharged automatically from pipeline, and in separator, remaining gaseous tension is less than water seal pressure, CO
2gas gas is blocked, and with water, does not discharge, and has prevented the waste of unstripped gas, increases urea production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A unstripped gas gas and water separator, comprises air water separator 1, is respectively arranged with urea unstripped gas and enters tracheae 2, CO on air water separator 1
2gas outlet pipe 3 and Separation of Water relief outlet 4, on Separation of Water relief outlet 4, be connected with water shoot 6, on water shoot 6, be provided with and drench valve 5, in water-sealed container 9, be provided with water seal water 8, the water outlet 7 of water shoot 6 is arranged in water-sealed container 9 in the water seal water 8 arranging, and the pressure at water outlet 7 places of water shoot 6 is greater than the pressure of the urea unstripped gas in air water separator 1.
The pressure at water outlet 7 places of water shoot 6 is 20 kPas, and the pressure of the urea unstripped gas in air water separator 1 is 13 kPas.
At urea CO
2the blowdown of compressor inlet separator increases and to be highly 2 meters, and it is the water seal of 20 kPas that maximum is born pressure; The isolated moisture of separator is all discharged from pipeline, and CO
2gaseous tension is less than water seal maximum and bears pressure, can not discharge with water, thereby guarantee CO
2gas is not wasted.
Claims (2)
1. a urea unstripped gas gas and water separator, comprises air water separator (1), is respectively arranged with urea unstripped gas and enters tracheae (2), CO on air water separator (1)
2gas outlet pipe (3) and Separation of Water relief outlet (4), it is characterized in that, on Separation of Water relief outlet (4), be connected with water shoot (6), on water shoot (6), be provided with and drench valve (5), in water-sealed container (9), be provided with water seal water (8), the water outlet (7) of water shoot (6) is arranged in the water seal water (8) arranging in water-sealed container (9), and the pressure of locating at the water outlet (7) of water shoot (6) is greater than the pressure of the urea unstripped gas in air water separator (1).
2. a kind of urea unstripped gas gas and water separator according to claim 1, is characterized in that, the pressure that the water outlet (7) of water shoot (6) is located is 20 kPas, and the pressure of the urea unstripped gas in air water separator (1) is 13 kPas.
