Detailed Description
Embodiments of the present utility model will be described in more detail below with reference to the drawings and reference numerals, so that those skilled in the art can practice the present utility model after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The utility model provides a concentrated water seal explosion-proof area wastewater discharge system as shown in fig. 1-2, which comprises a plurality of reaction kettles 10, wherein the drain pipes of the reaction kettles 10 are connected to a drain header pipe 20, the drain header pipe 20 is connected to a water seal well 30, and wastewater is discharged from a wastewater pipe 40 after the water seal well 30 is used for primarily separating organic solvent which is insoluble in water and enters the next procedure. The waste 40 is also provided with an inspection well 60. The water seal well 30 is intensively used for draining water of a plurality of reaction kettles 10 in the same explosion-proof area, so that the number of the water seal wells can be reduced, the cost is reduced, the space utilization rate of an outdoor site is improved, and an installation space is provided for wastewater treatment equipment and a solvent recovery tank.
In this embodiment, the water seal well 30 includes a tank body 31, a partition wall 34 that divides the tank body 31 into an oil-separating cavity 32 and a water drainage cavity 33 is disposed in the tank body 31, and the oil-separating cavity 32 and the water drainage cavity 33 are both provided with a well cover 35. The oil separation cavity 32 is provided with a water inlet three-way pipe 321, a first end of the water inlet three-way pipe 321 is connected with the water drainage main pipe 20, a second end of the water inlet three-way pipe 321 extends towards the bottom of the oil separation cavity 32, and a third end of the water inlet three-way pipe 321 is detachably connected with a plug 36; the water draining cavity 33 is provided with a water draining three-way pipe 331, a waste pipe 40 is connected to a first end of the water draining three-way pipe 331, a second end of the water draining three-way pipe 331 extends towards the bottom of the water draining cavity 33, a third end of the water draining three-way pipe 331 is detachably connected with a plug 36, and a second end of the water draining three-way pipe 331 is higher than the water passing port 341. The partition 34 is provided with a water passing port 341 that communicates the oil partition chamber 32 with the water discharge chamber 33.
After the wastewater enters the water seal well, a water seal is formed at the lower edge of the first end of the water discharge three-way pipe 331, and the second end of the water inlet three-way pipe 321 and the second end of the water discharge three-way pipe 331 extend into the water seal to isolate the mutual strings of combustible gas. Specifically, the second end of the water inlet tee 321 is flush with the second end of the water outlet tee 331, and the height H1 between the second end of the water outlet tee 331 and the lower edge of the first end of the water outlet tee 331 is greater than or equal to 250 mm.
After the water seal is formed, the wastewater enters the oil separating cavity 32, wherein the organic solvent insoluble in water floats up to the top of the oil separating cavity 32 and is blocked by the partition wall 34, and water enters the water draining cavity from the water passing port 341 at the bottom. The drainage of a plurality of reaction kettles is concentrated and uses a water seal well 30, and the flow rate and the flow velocity of wastewater entering the water seal well 30 can be multiplied. In the prior art, due to the increase of the flow velocity and the flow quantity of the wastewater, part of the organic solvent which is insoluble in water is not separated from the water, and is carried by the wastewater to directly flush into the drainage cavity from the gap between the partition plate and the bottom of the tank body, so that the oil-water separation effect of the partition plate is poor. In order to solve this problem, in the present embodiment, a flow blocking ridge 342 is disposed between the water passing opening 341 and the bottom of the tank body 31 to block the water flow directly flowing from the bottom of the tank body 31 to the drainage cavity, and guide the water flow to the upper middle portion of the oil separating cavity 32, so that the water-insoluble organic solvent has sufficient time to separate from the water and float upwards, and the water flows into the drainage cavity again, thereby enhancing the oil-water separation effect. The flow blocking ridge 342 protrudes into the oil separating chamber 32, so that the upward water flow is relatively far away from the water passing opening 341.
Preferably, the oil-separating chamber 32 has a larger volume than the water-discharging chamber 33. In the present embodiment, the width of the oil-separating chamber 32 is larger than that of the water-discharging chamber 33 to increase the time for separating the water-insoluble organic solvent from the water and the space for accommodating the solvent.
Preferably, the height of the baffle ridge 342 is greater than or equal to 300 mm.
Preferably, the oil discharging device further comprises an oil suction pipe 50 extending into the oil separating cavity 32 and an oil discharging pump connected with the oil suction pipe 50, wherein the tail end of the oil suction pipe 50 is higher than the water passing port 341. When the volume above the water passing port is gradually filled with the organic solvent which is insoluble in water in the oil separation cavity, part of the solvent flows into the water discharging cavity from the water passing port. The solvent amount on the surface of the liquid in the drain cavity of the well cover is checked at regular time, and if the liquid level is covered by the solvent, the oil drain pump is opened to timely suck the solvent in the oil separating cavity.
Preferably, the height difference H2 between the end of the oil suction pipe 50 and the water passing port 341 is greater than or equal to 100 mm.
The foregoing is a description of one or more embodiments of the utility model, which are specific and detailed, but are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
