Abstract
The utility model discloses a naphthalene removal and exhaust gas emission device of a sulphonating kettle, and belongs to the technical field of naphthalene water reducer production equipment. The device comprises an exhaust pipeline connected with a sulphonating kettle exhaust opening, wherein the exhaust pipeline is connected with a gas upstream pipeline; the gas upstream pipeline is connected with a raw naphthalene downstream pipeline used for preventing raw naphthalene from entering the exhaust pipeline; and the raw naphthalene downstream pipeline and the gas upstream pipeline are arranged on two sides of the exhaust pipeline. By adopting the device, after exhaust gas containing the raw naphthalene enters the gas upstream pipeline from the exhaust pipeline and is cooled, the raw naphthalene directly falls into the raw naphthalene downstream pipeline instead of the exhaust pipeline, so as not to fall back into a sulphonating kettle, so that the device effectively prevents the raw naphthalene from falling back into the sulphonating kettle and from producing attachments, and further guarantees the product quality.
Description
Technical field
The utility model belongs to naphthalene water reducer production equipment technical field, relates in particular to a kind of sulfonation still and takes off the naphthalene gas emission device.
Background technology
The main component of naphthalene water reducer is β base naphthalene sulfonic acid-formaldehyde condensation product, it is a kind of non-bleed type water reducer, this naphthalene water reducer is good to various cement adaptabilities, can improve concrete operability, is widely used in engineerings such as highway, railway, bridge, tunnel, power station, dam, skyscraper.
Naphthalene water reducer is to make by synthetic methods such as sulfonation, hydrolysis, condensation, neutralization, filtration and dryings, and the living naphthalene in the sulfonation still has the physical characteristic of distillation owing to give birth to naphthalene in sulfonation process, thereby produces the tail gas that contains a large amount of living naphthalenes.At present, mainly take to give birth to the naphthalene gathering-device and recycle giving birth to naphthalene, but in giving birth to the naphthalene collection process, give birth to naphthalene and easily fall back to and generate attachment in the sulfonation still and cause poor product quality.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of sulfonation still to take off the naphthalene gas emission device, fall back in the sulfonation still and to generate the technical problem that attachment causes poor product quality to solve living naphthalene.
For solving the problems of the technologies described above, the technical solution of the utility model is: the sulfonation still takes off the naphthalene gas emission device, comprise the discharge duct that connects described sulfonation still exhaust outlet, described discharge duct connects the gas up-hill line, described gas up-hill line is connected with for stoping and gives birth to the descending pipeline of living naphthalene that naphthalene enters described discharge duct, and the descending pipeline of described living naphthalene and described gas up-hill line are positioned at the both sides of described discharge duct.
As a kind of improvement, the angle between described discharge duct and the described gas up-hill line is acute angle or right angle.
As further improvement, be provided with cooling device in the described gas up-hill line.
As further improvement, described cooling device comprises the coil pipe that is communicated with cooling water, and the water inlet of described coil pipe and delivery port stretch out described gas up-hill line.
As further improvement, series connection is provided with at least two described coil pipes in the described gas up-hill line.
After having adopted technique scheme, the beneficial effects of the utility model are: because described discharge duct connects the gas up-hill line, described gas up-hill line is connected with for stoping and gives birth to the descending pipeline of living naphthalene that naphthalene enters described discharge duct, the descending pipeline of described living naphthalene and described gas up-hill line are positioned at the both sides of described discharge duct, thereby after the tail gas that contains living naphthalene enters the cooling of gas up-hill line from discharge duct, give birth to naphthalene and directly fall into the descending pipeline of living naphthalene, can not fall into gas exhaust piping, and then can not fall back in the sulfonation still, effectively avoid living naphthalene to fall back in the sulfonation still and generated attachment, and then guaranteed the quality of product.
Because the angle between discharge duct and the described gas up-hill line is acute angle or right angle, thereby living naphthalene is difficult for falling into gas exhaust piping more.
Owing to be provided with cooling device in the described gas up-hill line, thereby can separate from mist giving birth to naphthalene faster.
Because series connection is provided with at least two described coil pipes in the described gas up-hill line, thus contain the tail gas of living naphthalene can cooling fully in the gas up-hill line, guarantee to give birth to the sufficient condensation of naphthalene.

Among the figure, 1, sulfonation still exhaust outlet, 2, discharge duct, 3, the gas up-hill line, 4, give birth to the descending pipeline of naphthalene, 5, cooling device, 51, coil pipe, 52, water inlet, 53, delivery port, 54, water pipe;
Hollow arrow represents that tail gas trend, filled arrows represent to give birth to naphthalene steam trend, the round dot arrow living naphthalene trend of representing to sublimate.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the sulfonation still takes off the naphthalene gas emission device, comprise the discharge duct 2 that connects sulfonation still exhaust outlet 1, discharge duct 2 connects gas up-hill line 3, gas up-hill line 3 is connected with for stoping and gives birth to the descending pipeline 4 of living naphthalene that naphthalene enters discharge duct 2, the living descending pipeline 4 of naphthalene and gas up-hill line 3 are positioned at the both sides of discharge duct 2, and the angle between discharge duct 2 and the gas up-hill line 3 is acute angle or right angle, is preferably acute angle.
Be provided with cooling device 5 in the gas up-hill line 3, cooling device 5 comprises the coil pipe 51 that is communicated with cooling water, water inlet 52 and the delivery port 53 of coil pipe 51 stretch out gas up-hill line 3, also can feed other cooling fluids in the coil pipe 51 certainly, thereby can separate from mist giving birth to naphthalene faster.
Series connection is provided with at least two coil pipes 51 in the gas up-hill line 3, the delivery port 53 of adjacent coil pipe 51 is connected by water pipe 54 with water inlet 52, the quantity of coil pipe 51 can be set according to the ratio that contains living naphthalene steam in the tail gas, preferably be set to 3, to guarantee not contain living naphthalene steam in the final discharge tail gas.
The sulfonation still that the utility model provides takes off the naphthalene gas emission device, because discharge duct 2 connects gas up-hill line 3, gas up-hill line 3 is connected with for stoping and gives birth to the descending pipeline 4 of living naphthalene that naphthalene enters discharge duct 2, the living descending pipeline 4 of naphthalene and gas up-hill line 3 are positioned at the both sides of discharge duct 2, thereby after the tail gas that contains living naphthalene steam enters 3 coolings of gas up-hill line from discharge duct 2, the living naphthalene of sublimating directly falls into the descending pipeline 4 of living naphthalene, can not fall into gas exhaust piping 2, and then can not fall back in the sulfonation still, effectively avoid living naphthalene to fall back in the sulfonation still and generated attachment, and then guaranteed the quality of product.
