Description

The energy saving and environment friendly hydrophobic row's silt device of flue gas desulfurization chimney highly effective

Technical field

The present invention relates to a kind of hydrophobic row's silt device of energy-conserving and environment-protective flue gas desulfurization chimney highly effective.

Background technology

Through chimney high altitude discharge after flue gas desulfurization and dedusting is up to standard, still have micro dust and steam in flue gas, in chimney on Because Action of Gravity Field falls to inner wall of stack during rising, chimney bottom is flow to, typically is arranged right below discharging in chimney bottom Pipe and valve periodically discharge sludge, and chimney otherwise can be caused to be condensed and settle underflow blocking, overhaul of the equipments and spoil disposal want high-altitude to make Industry, it is dangerous big, while air-tightness is impacted in chimney during sludge discharge, low dense waste gas is spilt from floss hole, deteriorates operation ring Border.

The content of the invention

The purpose of the present invention proposes a kind of energy saving and environment friendly hydrophobic row of flue gas desulfurization chimney highly effective aiming above mentioned problem Silt device, the device can efficiently dredge the ponding of flue gas desulfurization chimney automatically, discharge silt dirt, keep chimney unobstructed, avoid people The danger of work work high above the ground cleaning, simple and convenient, safety and environmental protection, low cost, easily promotes, overcomes problem of the prior art with this.

The purpose of the present invention is realized by following means：

A kind of hydrophobic row's silt device of energy saving and environment friendly flue gas desulfurization chimney highly effective, it has drain trap one and drain trap two, its It is characterised by that drain trap one and drain trap two are closed container, there is upper catheter connection, the entrance of upper catheter between the two Positioned at the top overfall of drain trap one, outlet keeps gap positioned at the bottom of drain trap two and with bottom surface；Drain trap one is led Flow tube connects with high-altitude chimney bottom, and a filler pipe with gate valve respectively arranged at the top of drain trap one and drain trap two, and bottom is each There is a bottom blow-off pipe with gate valve, the top of drain trap two has a top blow-off pipe to be communicated with outside, top comb Entrance is located at the overfall of drain trap two.

The mozzle reaches one section of inclination at the top of drain trap one, and one section into drain trap one is vertical, to mitigate Impulsive force of the sewage to tank body.

The mozzle has control valve, to control sewage to enter the amount and speed of tank body.

The upper catheter reaches one section of level of drain trap two, and one section into drain trap two is vertical.

The outlet of the top blow-off pipe and draft tube outlets, and the outlet of upper catheter are in the same horizontal position.

Respectively there is one piece of draining baffle plate before the overfall of drain trap one and drain trap two, to stop that solid suspension flows out.

Drain trap two can be by one or more drain traps of top drainpipe series connection, to strengthen detergent power.

The operation principle of the present invention is as follows：

Desulfurization fume by purification enters high-altitude by straight flue and rises chimney, and a small amount of aqueous vapor and dust exist in flue gas Chimney bottom is deposited under Action of Gravity Field, by mozzle by the drain trap one on underflow guiding ground, and enters one in canister Sedimentation separation is walked, clear liquid accumulation rising is discharged into from upper catheter overfall in drain trap two and further supernatant, supernatant accumulation Rising is automatically drained out from top drainpipe overfall, into surface collection ditch, the dirt of drain trap one and the inside of drain trap two deposition Mud periodically alternately discharges from tank body lower part blow-off pipe., can be to tank interior by the injected clear water of top filler pipe 5 after row is become silted up Residual mud is rinsed totally, or filling clear water flooded mozzle lower end and plays sealing function.

The present invention can efficiently dredge the ponding of flue gas desulfurization chimney automatically, discharge silt dirt, keep chimney unobstructed, avoid people The danger of work work high above the ground cleaning, simple and convenient, safety and environmental protection, low cost, is easily promoted.

Beneficial effect can also be specifically summarized as follows：

1）, chimney bottom silting lead to the hydrophobic row's silt device in ground through mozzle, change high-altitude blowdown operation as ground Face operation, workload are greatly reduced, easy management and control, and safety improves；

2）, after this hydrophobic row's silt device in ground of increase, muddy water further can be settled further in shelf jar body, be had Recycled beneficial to sludge dust, realize minimum discharge；

3）, two drain trap alternating discharge sludge, flue gas is in sealing state all the time, avoid flue gas from leaking, improve behaviour Make environment；

4）, mozzle be provided with valve, easy access；

5）, mozzle oblique cutting enter the top of drain trap one, play cushioning effect, avoid muddy water from vertically falling into and cause equipment to damage Wound, thus service life of equipment is grown；

6）, be provided with shelves drain bar before two drain trap top overfalls, be more beneficial for muddy water sedimentation separation.

Embodiment

The present invention is further illustrated below in conjunction with the accompanying drawings.These explanations are to preferably express and understand having for the present invention Beneficial effect, rather than the limitation present invention.

As shown in figure 1, the hydrophobic row's silt device of this high-efficiency flue gas desulfurization chimney of the present invention, including high-altitude chimney bottom row Dirty mozzle 1, mozzle are provided with control valve 2, and mozzle mitered enters ground drain trap 1, while extends vertically into tank body Interior, the top of drain trap one has upper catheter 4 to be connected and extend vertically into inside drain trap two, two drain traps with the top of drain trap two Filler pipe 5 and ball valve 6 are arranged at top.The outlet of top drainpipe 7 of drain trap two is located at overfall, exports to up to surface collection ditch. Before the draining plate washer 8 of two drain traps is located at respective overfall, hydrophobic pot bottom respectively sets portion's blow-off pipe 9 and Hand-operated butterfly valve 10。

NM parts and label are as described above.

As it was previously stated, drain trap one and drain trap two are closed container.They can be cylindrical shape, square tube shape, or The shapes such as person's geometrical combination shape, size is preferably equal, so that disposal ability is mutually matched.The overfall is exactly that liquid flows naturally The position gone out.

Element of installation material referred to above is non-metal anti-corrosion material.

Before the present invention, applicant's unit can periodically or non-periodically be entered to ensure the unimpeded of flue gas desulfurization chimney Row work high above the ground, it is exactly that worker is lifted or climbed to tens meters of high throats, operation in chimney barrel is entered back into, by mud Clear, it is extremely inefficient, and also light is extremely weak in chimney barrel, and air oxygen content is low, and the life and health of worker is threatened very Greatly.After using the present invention, the sludge in chimney flows in drain trap automatically with ponding to be precipitated and purifies automatically, not only can be with The clear water being purified returns to be used in production, can also obtain the mud rich in valuable metal, is made for regenerated resources use, together When ensure that chimney is unimpeded, normal production, save a large amount of production costs.This measure is that applicant's unit brings significant economy and society Can benefit.By worker's welcome consistent with cadre's.
