The environment-friendly liquid ring pump is conveyed by the first water pump and the second water pump at the same flow rate in the using process, and water in the shell is continuously replaced by water in the circulating water tank, so that the water temperature of the water in the shell can be kept at a lower temperature, and the volatilization of an organic solvent is reduced.
In the above technical scheme, preferably, a temperature sensor is arranged in the liquid ring pump casing, the temperature sensor is connected with a control device, and the control device is connected with the first water pump and the second water pump. Adopt this structure can have the temperature sensor response casing in the temperature, when reaching the settlement temperature, controlling means control first water pump and second water pump start, with the water in the water circulation tank constantly the water in the replacement casing, and when the temperature was less than the settlement temperature, first water pump and second water pump did not start, played energy-conserving effect.
In the above technical scheme, preferably, the circulation water tank is provided with a cooling jacket, the cooling jacket is connected with a third water pump for introducing brine ice through a connecting pipeline, and the third water pump is connected with the control device. The water in the circulating water tank can be cooled by introducing ice salt water into the jacket through the third water pump, so that the water temperature of the water entering the shell is reduced.
In the above technical scheme, preferably, a transparent observation port for observing the liquid level is arranged on one end face of the shell, and an indication scale is arranged on the transparent observation port. Adopt this structure can observe the water level in the casing through transparent viewing aperture, prevent that the water level from crossing excessively or the normal operating that the water level is too high influences the liquid ring pump.
Compared with the prior art, the utility model, following beneficial effect has: the environment-friendly liquid ring pump is conveyed by the first water pump and the second water pump at the same flow rate in the using process, and water in the shell is continuously replaced by water in the circulating water tank, so that the water temperature of the water in the shell can be kept at a lower temperature, and the volatilization of an organic solvent is reduced.
