Detailed Description
In the description of the present utility model, it should be understood that the description of indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description and to simplify the description, rather than to indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present utility model.
In the description of the present utility model, it should be noted that, unless explicitly stated and limited otherwise, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The technical scheme of the utility model is as follows:
referring to fig. 2, the spinneret plate cleaning device of the utility model comprises a cleaning tank, wherein a solvent inlet pipe 1, an overflow pipe 2 and a spraying plate 3 are arranged in the cleaning tank, the spraying plate 3 is arranged in the cleaning tank at intervals, and an inner cavity of the spraying plate is communicated with the solvent inlet pipe 1. The overflow pipe 2 is perpendicular to the bottom of the cleaning tank, an overflow port 21 is formed in the opening at the top, so that the solvent overflows back to the DMAC storage tank (the sealed storage tank is provided with a heating jacket outside or a heating coil inside and is used for heating the solvent) at the position of the overflow port 21, and the solvent is cleaned in a circulating and closed mode through a circulating pump.
In a further technical scheme, the cleaning tank is provided with an upper cover 4 hinged with the tank body. Since DMAC has a pungent smell, the upper cover 4 serves to seal the cleaning tank.
In a further technical scheme, the side wall of the cleaning tank is provided with an air outlet 5, and the height of the air outlet 5 is required to be higher than that of the overflow port 21. DMAC gas generated in the cleaning process is exhausted through the exhaust port 5, and the gas enters a tail gas treatment system (comprising a spray tower) for treatment until reaching the standard and can not be discharged.
In a further technical scheme, a drain outlet is arranged at the bottom of the cleaning tank, the cleaned waste liquid is pumped into a refining recovery system through the drain outlet, water is removed through a first distillation tower of the tower, then the waste liquid enters a second refining tower of the tower to neutralize acid, alkali and conductivity, and the waste liquid is recycled after the treatment index is normal.
In a further technical solution, the spraying plates 3 are symmetrically distributed on two sides of the solvent inlet pipe 1, and a cavity for placing the spinneret plate 100 is formed between every two spraying plates on the same side. In this embodiment, a maximum of 6 spinnerets 100 may be cleaned simultaneously, each spinneret 100 being placed within a respective cavity, as shown in fig. 3.
In a further technical scheme, the two adjacent spray plates 3 are connected and fixed by a connecting plate 6 at one side close to the solvent inlet pipe 1. This is because the solvent with a certain pressure enters the spray plate from the solvent inlet pipe, and the pressure is larger as the solvent inlet pipe is closer, so that the solvent needs to be supported and fixed so as not to deform.
In a further technical solution, a plurality of groups of injection holes 31 are provided on a side of the injection plate 3 facing the spinneret plate 100, each group of injection holes 31 is distributed in a circular shape, and each circular injection hole group 31 is arranged at intervals. The circular spray holes 31 are distributed in two rows and columns on the spray plate as shown in fig. 4. In this arrangement, the solvent is caused to radiate against the corners of the spinneret 100, thoroughly cleaning the interior of the cavity of the spinneret 100. A pressure value of 30 kg (namely 3 MPa) is set on the pump to play a role in pressure injection.
The original immersion cleaning mode is adopted, and the cleaning effect is not understood. After improvement, a spray mode is adopted, solvents are sprayed on two sides of the spinneret plate opposite to the spinneret plate, hot DMAC is conveyed by the pump and sprayed out under pressure, the inside of the cavity of the spinneret plate can be cleaned, the solvents overflow back to the DMAC storage tank through the overflow pipeline for circular cleaning, DMAC gas generated in the cleaning process enters the tail gas treatment system through the exhaust port, and waste liquid after cleaning is pumped into the refining recovery system through the drain port, as shown in fig. 5. In addition, through placing a plurality of rows of spray plates, the cleaning efficiency is improved.
While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that the specific embodiments described are illustrative only and not intended to limit the scope of the utility model, and that equivalent modifications and variations of the utility model in light of the spirit of the utility model will be covered by the claims of the present utility model.
