Description
Technical field
The utility model belongs to industrial smoke denitration device technical field, is specially the two-way water-gland of a kind of tank used for storing ammonia.
Background technology
NOx is one of main atmosphere pollution, quite serious to the harm of human body.NO can make the nervous centralis of people benumb and cause death by suffocation; NO
2toxicity ratio NO stronger, asthma and pulmonary emphysema can be caused, cause the afunction of the heart of people, lung, liver, kidney and hematopoietic tissue.Oxides of nitrogen becomes in rain process at air, is formed acid rain and Los Angelos smog, havoc earth ecology bad border by the drop absorption that condensation vapor becomes.Selective catalytic reduction (SCR) technology is under catalyst action, deoxidation compound NH
3(liquefied ammonia, ammoniacal liquor, urea etc.) and the NO in flue gas
xreaction, by the NO in flue gas
xbe reduced to the nitrogen N of nontoxic pollution-free
2with water H
2o.Its reactor is arranged between boiler economizer outlet and air preheater entrance, and temperature of reaction is generally between 320 DEG C-400 DEG C, and SCR method denitration technology is the denitration technology of most mature and reliable both at home and abroad at present, and denitration efficiency is high, and security of system is stablized.
Tank used for storing ammonia in flue gas denitrification system and ammonia water spray device, by pipeline communication, will be stated the ammonia atomization of tank used for storing ammonia and spray into 850 ~ 1000 DEG C of high-temperature areas of cement kiln.How high efficiente callback ammonia, the equilibrium of pressure controlled in tank used for storing ammonia are the gordian techniquies in selective catalytic reduction technology.The special breathing valve balance tank used for storing ammonia pressure that existing tank used for storing ammonia is arranged by tank deck, breathing valve complex structure, and the unnecessary ammonia needing that external pipe and external water tank dissolving breathing valve discharge.
Summary of the invention
Adopt breathing valve to need the problem of external pipe and external water tank for ammonia storage tank, the utility model proposes the two-way water-gland of a kind of tank used for storing ammonia.
The two-way water-gland of tank used for storing ammonia of the present utility model, its structure is sealed shell of tank, is positioned over tank used for storing ammonia top, it is characterized in that:
Above tank body, induction opening is set; Arrange horizontal baffle in tank body, tank body is divided into upper and lower two cavitys by horizontal baffle, horizontal baffle is arranged drainage pipeline I and vertical pipe; Upper cavity side is communicated with inlet channel; Tank base arranges vertical partition plate, and lower chamber is divided into independent water space by vertical partition plate, and the tank base of vertical partition plate both sides arranges drainage pipeline II and drainage pipeline III; Upper cavity arranges with lower chamber side the three-way pipeline be communicated with air, and the three-way pipeline saliva mean place in upper cavity is lower than the top pipeline opening of vertical pipe; Valve is set in described drainage pipeline I, drainage pipeline II and drainage pipeline III and all accesses tank used for storing ammonia.
During work, close the valve of drainage pipeline I and drainage pipeline III, by inlet channel, water is accessed two-way water-gland, above the water flooding vertical pipe of upper cavity, pipeline opening enters the water space of lower chamber side; When the ammonia volatilized in tank used for storing ammonia is by induction opening access to plant, ammonia gas dissolves enters in the water in upper and lower cavity to form ammoniacal liquor, and when reaching capacity, tank body internal gas pressure increases, and the ammoniacal liquor of upper cavity is pressed into lower chamber by three-way pipeline; Meanwhile, air pressure is by the ammoniacal liquor press-in lower chamber in vertical pipe, and saturated ammoniacal liquor flooded the water space that vertical partition plate flows into lower chamber opposite side, and was again back to tank used for storing ammonia again to utilize by the drainage pipeline II of bottom.Drainage pipeline I and drainage pipeline III can be opened as required at any time.
As preferably, for security consideration, explosionproof hole is set at tank body top.
The two-way water-gland of tank used for storing ammonia of the present utility model, replaces the breathing valve of circle tank used for storing ammonia, when in tank, malleation reaches certain value, and breath (NH
3) absorb after dissolving through this device, periodic exhaustion absorption liquid utilizes to storage tank, without the need to pumping.Air is sucked when negative pressure in tank reaches certain value.Two-way water-gland can make tank body internal and external pressure balance, avoids the interior pressure of the ammonia tank caused when ammoniacal liquor is decomposed into ammonia and increases, effectively avoid breakdown and explosion hazard.It also avoid contaminated environment when ammonia steam is arranged outward.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, induction opening 1, horizontal baffle 2, drainage pipeline I3, vertical pipe 4, inlet channel 5; Vertical partition plate 6, drainage pipeline II7 and drainage pipeline III8; Three-way pipeline 9, explosionproof hole 10.
Detailed description of the invention
Embodiment 1: the two-way water-gland of tank used for storing ammonia, its structure is sealed shell of tank, is positioned over tank used for storing ammonia top, it is characterized in that: arrange induction opening 1 above tank body; Arrange horizontal baffle 2 in tank body, tank body is divided into upper and lower two cavitys by horizontal baffle 2, horizontal baffle 2 is arranged drainage pipeline I3 and vertical pipe 4; Upper cavity side is communicated with inlet channel 5; Tank base arranges vertical partition plate 6, and lower chamber is divided into independent water space by vertical partition plate 6, and the tank base of vertical partition plate 6 both sides arranges drainage pipeline II7 and drainage pipeline III8; Upper cavity arranges with lower chamber side the three-way pipeline 9 be communicated with air, and the 9 mouthfuls of water mean places of the three-way pipeline in upper cavity are lower than the top pipeline opening of vertical pipe 4; Valve is set in described drainage pipeline I3, drainage pipeline II7 and drainage pipeline III8 and all accesses tank used for storing ammonia.For security consideration, explosionproof hole 10 is set at tank body top.
