Abstract
The utility model relates to a naphthalene-scrubbing system of a final-cooling tower. The naphthalene-scrubbing system comprises the final-cooling tower, wherein an ammonia water pipe with a valve is connected at the upper part of the final-cooling tower; a naphthalene-scrubbing pump is connected on the ammonia water pipe behind the valve, and is connected with a water storage tank; the water storage tank is connected with an underground-water-emptying tank through a pipeline; the water storage tank is in a closed state; a self-priming pump is adopted as the naphthalene-scrubbing pump; and the water storage tank is higher than the naphthalene-scrubbing pump. The self-priming naphthalene-scrubbing pump is additionally arranged and can be mounted on the ground; the closed water tank is higher than the naphthalene-scrubbing pump; the naphthalene-scrubbing pump, the water storage tank and the underground-water-emptying tank are connected together, and then are butted with a hot ammonia water pipeline; therefore, inlet water for naphthalene scrubbing comprises hot ammonia water and water in the naphthalene-scrubbing pump, the inlet water amount is increased, and the naphthalene scrubbing effect is obvious. After the naphthalene-scrubbing system is mounted, the final-cooling tower only needs to be replaced after three to four months, the resistance for the final-cooling tower is relatively stable, and the operation is normal.
Description
Technical field
The utility model relates to the naphthalene system of washing of final cooling tower.
Background technology
At coal chemical enterprise, final cooling tower need be washed naphthalene to tower with a period of time, and washing naphthalene at present all is to connect an ammonia-feeding pipe on the top of final cooling tower, in tower, feeds hot ammoniacal liquor, carries out naphthalene washing process.Each moon is switched final cooling tower one time like this, increases workman's the amount of labour, and the final cooling tower resistance raises fast, and is high with hot ammoniacal liquor purge column frequency, careless slightly will the causing the accident of operation in the process of purge column.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency provides a kind of final cooling tower to wash the naphthalene system.
The purpose of the utility model realizes through following technical scheme:
A kind of final cooling tower is washed the naphthalene system, comprises final cooling tower, and final cooling tower top is connected with the ammonia water pipe of band valve, on the ammonia water pipe of valve back, is connected with and washes the naphthalene pump, washes the naphthalene pump and is connected with water tank.
Above-mentioned final cooling tower is washed the naphthalene system, and water tank is connected through pipeline with underground water emptying groove, and water tank is airtight water tank.
Above-mentioned final cooling tower is washed the naphthalene system, and the said naphthalene pump of washing is a self priming pump, and water tank is higher than washes the naphthalene pump.
Adopt technique scheme, the utility model has following advantage: owing to installed the self-priming naphthalene pump of washing additional, can install on the ground washing the naphthalene pump; Make an airtight water pot and setting height(from bottom) and be higher than and wash the naphthalene pump, will wash naphthalene pump, water tank, underground tank then and link up, dock with hot ammoniacal liquor pipeline again; Wash like this naphthalene water inlet comprise hot ammoniacal liquor and the water of washing in the naphthalene pump, increased inflow, it is obvious to wash the naphthalene effect; After the utility model is installed; Final cooling tower three just need be switched once to four months, and the final cooling tower resistance is more stable, and operation is normal.
Description of drawings
Fig. 1 is that traditional final cooling tower is washed naphthalene system architecture sketch map.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
A kind of final cooling tower as shown in Figure 2 is washed the naphthalene system, comprises final cooling tower 2, and final cooling tower 2 tops are connected with the ammonia water pipe 1 of band valve; On the ammonia water pipe 2 of valve back, be connected with and wash naphthalene pump 3; Wash naphthalene pump 3 and be connected with water tank 4, water tank 4 and underground water emptying groove 5 are connected through pipeline, and water tank is airtight water tank; The said naphthalene pump 3 of washing is self priming pumps, and water tank 4 is higher than washes naphthalene pump 3.
