Abstract
The utility model relates to a high-efficiency separator for tail gas of a device with sodium nitrate and sodium nitrite, which comprises a vertical middle housing that is provided on a base and is provided with a lower tail gas inlet and an upper tail gas outlet. The housing above the tail gas inlet is internally provided with two layers of fiber filtering bed units. A middle chamber of the housing is internally provided with a silk screen demister. A flow guiding pipe which is communicated with the bottom of the housing after passing through the silk screen demister is provided below the fiber filtering bed unit. The bottom end of the housing is provided with a liquid outlet which is communicated with the outer part of the base. Compared with the prior art, the high-efficiency separator for tail gas of the device with sodium nitrate and sodium nitrite has the following advantages: novel and reasonable structure, high convenience in operation, high separation precision and separation efficiency, stable performance, high applicability, and capability of trapping and separating acid mist with particle size in 0.01-1 micrometer. The high-efficiency separator for tail gas of the device with sodium nitrate and sodium nitrite is much better than the traditional separation equipment.
Description
Technical field
The utility model belongs to the separation equipment technical field, relates to a kind of nitric acid, two sodium device exhaust efficient cyclones that are suitable for containing the chemical industry production usefulness of nitric acid, two sodium (sodium nitrate, natrium nitrosum) medium.
Background technology
It is relatively backward to continue to use traditional isolation technics at present in the chemical industry that contains nitric acid, two sodium (sodium nitrate, natrium nitrosum) medium, the separation equipment structure is the combination that simple ghost equipment and silk screen are caught the foam unit, generally can only capture and separate the acid mist more than 100 microns, separation accuracy and separative efficiency are all very low.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, and then a kind of rational in infrastructure, easy to operate, separation accuracy and high nitric acid, the two sodium device exhaust efficient cyclones of separative efficiency are provided.
Technical solution for achieving the above object is such: the nitric acid that is provided, two sodium device exhaust efficient cyclones comprise a upright hollow housing that has bottom gas inlet and the outlet of upper end tail gas that is installed on the base, be provided with two-layer fiber filter bed unit in the housing above gas inlet, at the indoor horizontal wire mesh demister that is provided with in housing middle part, have the mozzle that passes to housing bottom after passing through slotting wire mesh demister, the logical leakage fluid dram of locating to base exterior outside the housing bottom is provided with in fiber filter bed unit.
Technical solution of the present utility model also comprises: be provided with discharge opeing choke device gas alarm mouth on the housing bottom sidewall, be respectively equipped with a liquid level warning mouth on housing bottom sidewall and base end wall.In addition, also respectively be provided with a differential manometer mouth at the top and the medium position place of housing sidewall.
Operation principle of the present utility model is such: the tail gas that contains sodium nitrate, natrium nitrosum particle, acid mist, nitrogen oxide enters the tail gas separator from the N1 mouth, revolve branch by machinery and separate impurity such as sodium nitrate particle more than the larger particles 100 μ m, nitric acid droplet, gas after overwinding divide to separate enters that fiber filter bed unit thoroughly purifies, demist, separation, and separative efficiency can reach more than 99%; Tail gas is entered by the filter bed skin, and internal layer flows out, and the acid mist in the tail gas is during by special fiber filter bed unit, and fiber filter bed unit captures impurity such as acid mists, is condensed into liquid membranaceously, flows downward under the gravity effect; The second layer fibre bed that is located at downstream, fiber filter bed unit can be assisted discharge opeing and can effectively be prevented the secondary entrainment; High-purity tail gas after the isolated by filtration is assembled at the inner chamber of fiber filter bed unit, discharges from exhaust gas filter top N2 mouth at last, enters down operation.When device separates is filtered tail gas, the acid mist of carrying secretly in the tail gas is agglomerated into big drop after capturing through fiber filter bed unit, drop is flowed to device bottom through the guide pipe of fiber filter bed unit, when amount of liquid and other impurity surpass certain altitude, can discharge from device bottom leakage fluid dram N6 cleaning.The leakage fluid dram valve can be controlled automatically also and can manually control.When discharging, gas must close the leakage fluid dram valve.
In order not influence separating effect and to judge fiber filter bed unit stopping state, respectively be provided with differential manometer mouth N3, a N4 in housing 1 side wall upper part and medium position place.Judge the stopping state and the separating effect of fiber filter bed unit by observe importing and exporting gas differential pressure, and then determine whether to change fiber filter bed unit or fiber filter bed unit is cleaned.
Compared with prior art, novel and reasonable structure of the present utility model, easy to operate, separation accuracy and separative efficiency height, stable performance, applicability are strong, and this separator can capture and separate 0.01～1 micron acid mist, is better than traditional separation equipment greatly.
