Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of other ways than those described herein, and those skilled in the art will be able to make similar generalizations without departing from the spirit of the invention. The invention is therefore not limited to the specific embodiments disclosed below.
The common external circulation evaporator at present is not provided with a sampling structure, and the equipment with the structure has the following defects: the operation of the device is affected: the concentration of the concentrated solution can not be detected, and the phenomenon of excessive concentration is easy to occur, so that the coke tube can be blocked. The operation is inconvenient because multiple observations are needed; repeated reductions in steam pressure are required; the operation efficiency is low, resulting in unstable whole concentration operation. Whether the concentration of the concentrated solution reaches the standard or not can not be detected when the equipment works. The operation of the device is affected. The utility model provides an outer circulation evaporimeter of easily getting a sample.
Referring to fig. 1, an external circulation evaporator easy to sample comprises a heating tank 1 and a separation tank 2, wherein a heat exchanger is arranged in the heating tank 1, and a feed liquid inlet 3 and a concentrated liquid outlet 4 are arranged at the bottom of the heating tank 1; the upper part of the heating tank 1 is connected with the separation tank 2 through an upper circulating pipe 5, and the bottom of the heating tank 1 is connected with the bottom of the separation tank 2 through a lower circulating pipe 6; the separation tank 2 is provided with a sampling valve 7.
In the above embodiment, the evaporimeter contains heating jar 1 and knockout drum 2, sets up sample valve 7 on knockout drum 2, can obtain the concentrate sample and detect concentration in real time through opening sample valve 7 in the evaporimeter separation working process, prevents concentrated excessively or concentrated not enough, and then has avoided the mistake that stifled pipe, coke breeze pipe lead to.
Further, as an embodiment of the present invention, the sampling valve 7 is located at the bottom of the lower circulation pipe 6. Since the lower circulation pipe 6 is located at the bottom of the evaporator, the extracting solution is influenced by gravity, and the concentration of the bottom is highest, so that the maximum concentration of the sample in the whole separation tank 2 can be obtained by obtaining the sample of the concentrated solution at the bottom of the evaporator and detecting the concentration, and the concentrated solution in the whole separation tank 2 is not excessively concentrated as long as the concentration at the bottom of the separation tank 2 is not excessively concentrated.
