Description

A CIP device on the top of a fermenter

technical field

The utility model relates to a position cleaning (CIP) device arranged on the top of a fermentation tank.

Background technique

In the CIP pipeline of the fermenter in the prior art, the sewage pipeline is directly arranged at the lower part of the emptying pipeline. This design does not consider environmental protection factors. When the emptying pipeline is cleaned in place (CIP), the lye flows directly through the sewage pipeline. to the environment, so this structure leads to a large loss of lye, resulting in waste of lye, but also increases the difficulty of environmental protection. According to calculations, an average of 23.8m ³ of lye with a concentration of 2% is wasted every day.

Therefore those skilled in the art always pay attention to how to improve the CIP device of the fermenter, to eliminate the above-mentioned lye waste phenomenon.

Contents of the invention

The purpose of this utility model is to provide a CIP device on the top of a fermenter that can solve the above problems.

In order to achieve the above object, the CIP device at the top of the fermenter described in the utility model adopts the following technical scheme: a CIP device at the top of the fermenter, which includes: an emptying pipeline connected to the top of the fermenter, the emptying The pipeline has a corner, wherein a sewage pipeline is arranged at the bottom of the corner of the emptying pipeline, and a first automatic on-off valve is arranged on the discharge end of the sewage pipeline, and a first automatic on-off valve is arranged between the first automatic on-off valve and the emptying pipeline. There is a return pipeline, the other end of which is communicated with the top of the fermenter, and a second automatic on-off valve is arranged on the return pipeline.

Further, the first automatic on-off valve is in the open state in the normal working state, and is in the closed state in the position cleaning state; the second automatic on-off valve is in the normally closed state in the normal state, and is in the position cleaning (CIP) state. The status is normally open.

After the implementation of the CIP device on the top of the fermenter with the above structure, the CIP cleaning and recovery of lye is effectively recovered, thereby reducing the cleaning cost and reducing the direct pollution of the lye to the environment.

Description of drawings

Fig. 1 is a schematic diagram of the structure of the CIP device on the top of the fermenter described in the present invention.

Detailed ways

In order to better understand the purpose, structural features and functions of the utility model, the structure, working process and functions of the preferred embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 is the schematic diagram of the structure of the CIP device at the top of the fermenter described in the utility model, as shown in the figure, the CIP device at the top of the fermenter includes: an emptying pipeline 1 connected to the top of the fermenter, the exhaust The empty pipe 1 has a corner 11, the emptying pipe 1 discharges the purified air in the furnace into the air, and the residue left in the corner 1 after purification needs to be cleaned regularly; the corner 11 of the emptying pipe 1 There is a sewage pipe 2 at the bottom, and a first automatic on-off valve 21 is set on the discharge end of the sewage pipe 2. The first automatic on-off valve is kept open in the normal state, and kept in the normal state during cleaning in place (CIP). closed; between the first automatic switch valve 21 and the emptying pipeline 1, a return pipeline 3 is provided, the other end of the return pipeline 3 communicates with the top of the fermenter, and the second automatic switch is provided on the return pipeline 3 The valve 31, the second automatic switch valve 31 is kept normally closed in the normal state, and kept normally open in the position cleaning (CIP);

Below in conjunction with the above-mentioned structure, describe the implementation process of the CIP device at the top of the fermenter described in the utility model, when transforming the CIP device at the top of the fermenter in the prior art, at first, measure and calculate the actual discharge flow velocity and the flow rate of the irrigation top sewage pipeline; then, Make equipment selection and engineering design based on the test data; then, add a new PLC control program according to the process CIP cleaning requirements, and update the control program after the on-site renovation is completed; finally, check whether the renovation project can operate normally, that is, under normal working conditions, Open the first automatic on-off valve 21, close the second automatic on-off valve, the waste liquid remaining in the emptying pipeline can be drained through the sewage pipeline 2; in the CIP cleaning process, close the first automatic on-off valve 21, open the second automatic on-off valve Open and close the valve, the lye can circulate in the emptying pipe 1 and the return pipe 3 so as to realize the geodesic cleaning of the emptying equipment and the recycling of the lye.

The CIP device on the top of the fermenter equipped with a return pipeline can effectively recover the CIP cleaning lye, thereby reducing the cleaning cost and reducing the direct impact of the lye on the environment.

The above is only a preferred embodiment of the CIP device at the top of the fermenter described in the present invention. It should be pointed out that for those skilled in the art, the Minor modifications and improvements should also be considered as belonging to the protection scope of the present utility model.
