Abstract
The invention relates to an ammonium nitrate technology steam demisting apparatus, which comprises a casing (1), a gas distribution device (2), a silk screen demister (3), a multilayer column plate (4) and a filter core demister (5) are provided in the casing from down to top. According to the invention, through silk screen demisting, the column plate absorption and the multistage absorption separating of annular demisting, ammonia and ammonium nitrate mist particles with 1 micrometer can be effectively separated in the technology steam, and the demisting efficiency is greatly enhanced, thereby the droplet separating effect of a technology steam by a despumation silk screen is not ideal, so that problems that NH3-N content in a steam condensate exceeds the standard and waste water processing load is increased can be solved. According to the invention, the annular demister can capture submicron mist particles through bump, interception and Brownian diffusion mechanism, separating efficiency can be enhanced, and the separation efficiency can reach 99.9%.
Description
Technical field
The present invention relates to a kind of ammonium nitrate process steam demister, it is applicable to the process steam washing demist workshop section after ammonium nitrate and composite fertilizer's neutralization reactor.
Background technology
The demist of existing ammonium nitrate neutralization reaction process steam is at the top of ammonium nitrate process steam scrubbing tower, a wire mesh demister to be housed, and it can tackle ammonia, ammonium nitrate droplet in process steam.But only complete above-mentioned demist with a wire mesh demister, its demist efficient is undesirable, can not catch the aerosol particle of submicron order, thereby cause ammonia, ammonium nitrate content in process steam that above-mentioned scrubbing tower discharges always high, increased in the rear end and the washing of scrubbing tower load, and cause NH3-N content overproof in process steam, increase load and the operating cost of Waste Water Treatment.
Summary of the invention
The objective of the invention is for the problem in prior art, a kind of demister of ammonium nitrate process steam scrubbing tower is provided, improve demist efficient.
For achieving the above object, technical scheme of the present invention is as follows:
It has a shell, be respectively equipped with a gas outlet and a circulation fluid outlet in described cover top portion and bottom, its special character is: be provided with successively a gas pipe, wire mesh demister, multilayer column plate and an annular demister in described shell from bottom to top, the air inlet of described gas pipe is the process steam import, be respectively equipped with sparge pipe and lower sparge pipe on the shell wall of described wire mesh demister top and bottom, be provided with a water supplement port on the shell wall above described multilayer column plate.
Further improved technical scheme of the present invention is as follows:
Described annular demister is made of two coaxial being nested of cylindrical filter cartridge at least.
The first pressure gauge and the second pressure gauge are housed respectively on the shell wall of described annular demister upper/lower terminal, and are provided with a spray thrower above annular demister.
Beneficial effect of the present invention is as follows:
One, the present invention absorbs through silk screen demist, column plate and separates with the multistage absorption of annular demist, greatly improved demist efficient, solved the not high and NH3-N content overproof in the steam condensate that causes of existing foam removal Efficiecy of Wire Net Demister, increased the series of problems such as wastewater treatment load.
Two, process structure of the present invention has adopted the demist process that absorbs step by step and capture, established technology steam is the preliminary interception by the foam removal silk screen first, then absorbs by column plate, filters through collision more at last to catch, can effectively separate ammonia, ammonium nitrate droplet below 1 micron, separative efficiency is high.
Three, annular demister of the present invention can be caught the droplet of submicron order by collision, interception and Blang's diffusion mechanism, has greatly improved separative efficiency, and its separative efficiency can reach 99.9%.
Four, the further improvement of the present invention is to make device can automatically clean annular demister.Namely when the pressure reduction of annular demister reaches setting value, automatically open spray thrower annular demister is sprayed cleaning, make demister remain on low voltage difference and move for a long time, extend its service life.
Five, the present invention utilizes gas pipe that steam inlet is disperseed, and makes air inlet be evenly distributed, thereby has reduced the impact to the demist internals, increases the service life.
Description of drawings
Fig. 1 is structure cross-sectional schematic of the present invention.
Fig. 2 is the A-A cross-section illustration intention of Fig. 1.
The specific embodiment
referring to Fig. 1, it has a shell (1), be respectively equipped with a gas outlet (1-1) and a circulation fluid outlet (1-2) in described cover top portion and bottom, be provided with successively a gas pipe (2) from bottom to top in described shell (1), a wire mesh demister (3), multilayer column plate (4) and an annular demister (5), the air inlet (2-1) of described gas pipe (2) is the process steam import, be respectively equipped with upper sparge pipe (3-1) and lower sparge pipe (3-2) on the shell wall of described wire mesh demister (3) top and bottom, be provided with a water supplement port (4-1) on the shell wall of described multilayer column plate (4) top.Wherein column plate is to adopt bubble cap plate or valve plate to be advisable.
Referring to Fig. 2, in order to make demist efficient better, described annular demister (5) is at least by the coaxial formation that is nested of two cylindrical filter cartridges (5-1,5-2).This routine inner core filter core (5-1) is a cylindrical shape filter core, and urceolus filter core (5-2) is assembled by eight demist plates and consists of.
Referring to Fig. 1,2, in order to extend the service life of annular demister, the first pressure gauge (7) and the second pressure gauge (8) are housed respectively on the shell wall of described annular demister upper/lower terminal, and are provided with a spray thrower (6) in the top of annular demister (5).
The course of work of this demister is: the process steam that contains gaseous ammonia, ammonium nitrate enters gas pipe (2) by air inlet (2-1), make process steam evenly by wire mesh demister (3) by gas distribution, by the time wherein larger drop tackled by silk screen, simultaneously, spray desalted water by upper sparge pipe (3-1) and lower sparge pipe (3-2) at the upper/lower terminal of silk screen, ammonia in absorption technique steam, ammonium nitrate, ammonia, ammonium nitrate absorb and drop separation thereby complete for the first time; Process steam continue to rise through three layers of column plate (4), process steam and reverse contact of desalted water from water supplement port (4-1) on column plate, and ammonia, the ammonium nitrate in absorption technique steam again, thus complete absorption for the second time; Process steam continues to rise by annular demister (5), respectively by inner core filter core (5-1) and urceolus filter core (5-2), gas is by collision and Blang's diffusion mechanism, the droplet of submicron order wherein is blocked, catches, thereby complete drop separation for the third time, (1-1) discharges steam after purification through the gas outlet, enters the rear end operation.Through above-mentioned multistage absorption and separation, avoided the generation of reentrainment fully, demist efficient is up to 99.9%.This device is after operation a period of time, can produce the salt made from earth containing a comparatively high percentage of sodium chloride crystalline particle on filter core in the annular demister, thereby make the upper/lower terminal of annular demister (5) produce certain pressure reduction, when the pressure difference that records when first, second pressure gauge (7), (8) reaches setting value, spray thrower (6) is opened, thereby annular demister (5) is sprayed cleaning, until pressure reduction recovers normal, spray finishes.This spray clean guaranteed this demister for a long time low voltage difference move continuously, long service life.
