Abstract
The utility model discloses a vacuum water tank sewage cooling and circulating device which comprises a vacuum water tank (1), a pump (2) and a cooling tower (3). The vacuum water tank (1), the pump (2) and the cooling tower (3) are serially connected to form a water circulating loop, a water outlet (5) of the vacuum water tank (1) is connected with a water inlet (7) of the cooling tower (3) through a connection pipe (6), the pump (2) is serially connected to the connection pipe (6), a water outlet (8) of the cooling tower (3) is connected with a water inlet (4) of the vacuum water tank, the water inlet (4) of the vacuum water tank is connected with a last-stage rectification device, and the device is characterized in that a condenser (9) is serially connected to the connection pipe (6) between the pump (2) and the water inlet (7) of the cooling tower (3). The condenser is serially connected to a vacuum water tank sewage cooling and circulating loop, and the condenser is used for cooling water in the loop in advance so that the work load of the cooling tower is reduced.
Description
Technical field
The utility model relates to a kind of rectifier unit sewage cooling-cycle device, especially a kind of EGR of disposing of sewage with vacuum water tank.
Background technology
The impurity that is produced in the distillation process often is drawn into it in vacuum water tank through vavuum pump, thereby impurity band is got back in the cooling water.Because the process of foreign substances also is drawn into the heat in the rectifier unit in the vacuum water tank, make that the cooling water in the vacuum water tank heats up, and the temperature in the vacuum water tank is high more, the vacuum of vacuum water tank is poor more.For this reason; Vacuum water tank is placed the cooling circuit that constitutes by vacuum water tank, pump and cooling tower series connection; Utilize pump that the sewage in the vacuum water tank is drawn in the cooling tower; Utilize cooling tower that the sewage in the closed circuit is cooled off, thereby unnecessary heat is siphoned away, at last in getting back to vacuum water tank.Adopt this mode, reduced sewage emissions frequency in the vacuum water tank, reduced pollution, reduced production cost environment.Along with the increase of concentration of wastewater in the vacuum water tank, closed circuit still need cool off the water in the loop again, must strengthen the intractability of cooling tower, the live load intensity of aggravation cooling tower.
Summary of the invention
The utility model technical problem to be solved provides a kind of vacuum water tank sewage cooling-cycle device, has the treatment effeciency height, the characteristics of energy-saving and emission-reduction.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of vacuum water tank sewage cooling-cycle device, comprise vacuum water tank, pump and cooling tower, and said vacuum water tank, pump and cooling tower series connection constitute a water-flow circuit; Said vacuum water tank is provided with a water inlet and a delivery port; The delivery port of said vacuum water tank is connected to the water inlet of cooling tower through tube connector, and said pump is serially connected on the tube connector, and the delivery port of said cooling tower connects the water inlet of vacuum water tank; The water inlet of said vacuum water tank connects the upper level rectifying device, and its innovative point is: be serially connected with condenser on the tube connector between said pump and the cooling tower water inlet.
The advantage of the utility model is: through serial connection one condenser in vacuum water tank sewage cooling circuit, utilize condenser to give that water cools off earlier in the loop, thereby reduce the live load of cooling tower.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Shown in Figure 1 is the structural representation of a kind of vacuum water tank sewage of the utility model cooling-cycle device.
The specific embodiment
Vacuum water tank sewage cooling-cycle device shown in Figure 1; Comprise vacuum water tank 1, pump 2 and cooling tower 3; Said vacuum water tank 1, pump 2 and cooling tower 3 series connection constitute a water-flow circuit; Said vacuum water tank 1 is provided with a water inlet 4 and a delivery port 5, and the delivery port 5 of said vacuum water tank 1 is connected to the water inlet 7 of cooling tower 3 through tube connector 6, and said pump 2 is serially connected on the tube connector 6; The delivery port 8 of said cooling tower 3 connects the water inlet 4 of vacuum water tank; The water inlet 4 of said vacuum water tank connects the upper level rectifying device, lowers the temperature for giving the sewage in the loop earlier in advance, on the tube connector 6 between the water inlet 7 of said pump 2 and cooling tower 3, is serially connected with a condenser 9.
During work, utilize pump 2 that the water in the vacuum water tank 1 is drawn into the water inlet 7 of cooling tower through condenser 9, utilize condenser to lower the temperature for earlier the sewage in the loop, then cool off, return at last in the vacuum water tank 1 through cooling tower 3.
