Abstract
The utility model discloses a naphthalene scrubbing system for a primary cooler. The system comprises a scrubbing liquid groove (2), wherein the scrubbing liquid outlet of the scrubbing liquid groove (2) is connected with the scrubbing liquid inlet of the primary cooler (1) through a naphthalene scrubbing pump (3); and the scrubbing liquid outlet of the primary cooler (1) is communicated with the scrubbing liquid inlet of the scrubbing liquid groove. Due to the adoption of the technical scheme, the naphthalene scrubbing effect is improved remarkably, the increase of resistance is slow, the scrubbing period of the primary cooler is prolonged from once every two months to once every half year, the operation flow is improved, the labor intensity is lowered, and stable production is facilitated.
Description
Technical field
The utility model belongs to the coal tar chemical technology field, is specifically related to a kind of primary cooler and washes the naphthalene system.
Background technology
By the discharge gas temperature that comes out is 80 ~ 90 ℃, contains a large amount of coal tar, steam and other materials.The effect of primary cooler is that the condensation of coal tar G&W steam is got off, and they are removed from coal gas, reduces gas volume, saves the coal gas transmitting power, helps reclaiming other chemical products.Owing to behind saturated coal gas entering primary cooler, steam and tar gas condensation are arranged, form very thin liquid film at tube wall, reduce heat transfer coefficient.In the path of back, because of the condensed tar amount is few, temperature is low, and the naphthalene crystal will be deposited on the tube wall, heat transfer coefficient is reduced heat transfer coefficient is reduced, and the coal gas circulating resistance increases.On coal gas rising path.Condensate also can be because of contact thermal coal gas and is partly evaporated, thereby has increased the content of naphthalene in the coal gas.Defectives such as existing primary cooler is washed the naphthalene system and existed clean result poor, and labor strength is big.It is fast to cause the primary cooler resistance to increase, and the coal gas that influences cold drum system goes out to send difficulty, must stop production cleaning once in average about two months, has seriously restricted the orderly function of producing.
The utility model content
The purpose of the utility model is to solve the above-mentioned technical problem that exists in the prior art, provides a kind of primary cooler to wash the naphthalene system.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
The primary cooler of the utility model is washed the naphthalene system, and this system comprises the washing lotion groove, and the outlet of washing lotion trough washery liquid is connected with the washing lotion import of primary cooler through washing the naphthalene pump, and the washing lotion outlet of primary cooler is communicated with the washing lotion import of washing lotion groove.
This system also comprises the condensation liquid bath, and the condensation liquid bath is connected with the washing lotion groove, and the condensation liquid bath is connected with ammoniacal liquor defecator (6) through condensate pump.
In the utility model, the proportioning of washing naphthalene liquid is an ammoniacal liquor 40%, condensate liquid 60%.Washing naphthalene liquid internal circulating load is 200m3/h.
Owing to adopt technique scheme, wash the naphthalene effect and rise appreciably, resistance increasess slowly, and has prolonged the primary cooler cleaning period, by original per two months once, be improved as every half a year once.Improve operating process, alleviated labour intensity, be more conducive to the production stable regulation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
It is as shown in Figure 1 that the primary cooler of the utility model is washed the naphthalene system, and this system comprises washing lotion groove 2, and the outlet of washing lotion groove 2 washing lotions is connected with the washing lotion import of primary cooler 1 through washing naphthalene pump 3, and the washing lotion outlet of primary cooler 1 is communicated with the washing lotion import of washing lotion groove.
This system also comprises condensation liquid bath 4, and condensation liquid bath 4 is connected with washing lotion groove 2, and condensation liquid bath 4 is connected with ammoniacal liquor defecator 6 through condensate pump 5.
