In coal chemical enterprise, the coal gas come out by coke oven initially enters primary cooler, most tar gas, big portion in coal gas
Divide steam and naphthalene to be condensed, provided safeguard for follow-up recovery of chemical products workshop section.The tar and naphthalene being condensed, which are attached to, to be changed
On heat pipe outer wall, cause exchange capability of heat to decline, therefore ammonia water spraying device is set in the top at interval of one section of heat exchanger tube, periodically
Carry out ammoniacal liquor sprinkling, cleaning heat exchange pipe outer wall.However, the mixture due to using tar ammonia in actual production, leads
Cause ammonia water spraying device outlet to be frequently occluded, it is necessary to which primary cooler is stopped work, ammoniacal liquor spray line is disassembled and cleared up, is operated
It is inconvenient.
The content of the invention
For overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of primary cooler flusher, realizes and is not stopping
Tar ammonia spray line is cleaned in the case of work, is easily installed, it is easy to operate.
To achieve the above object, the present invention is achieved through the following technical solutions：
A kind of primary cooler flusher, including spray line, tar ammonia mixture conduit, spray line mix with tar ammonia
Tar ammonia valve is connected between conduit, tar ammonia valve and tar ammonia mixture conduit are arranged on outside primary cooler；
Also include backwash tube, adpting flange lid, the cleaning jet chimney for being connected with steam valve, be connected with ammoniacal liquor valve
Cleaning ammoniacal liquor pipeline；
Backwash tube is arranged on above spray line, and the two is connected in spray line afterbody, and spray line and backwash tube are set
Inside primary cooler, backwash tube is connected by cleaning valve with cleaning jet chimney, cleaning ammoniacal liquor pipeline outside primary cooler；
Backwash tube is supported by flange connection cover with spray line and fixed.
Described adpting flange lid and the adpting flange of primary cooler passes through the spacing connection of alignment pin.
Described spray line bottom is symmetrically staggeredly provided with some sprinkling apertures or some anti-blocking sprayers, and spray line afterbody is set
Closure plate and support ring.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention can clean in the case where not stopping work to tar ammonia spray line, without disassembly, cleaning of stopping work,
It is easy to operation.Backwash tube is set above spray line, and by primary cooler outside Valve controlling spray line and backwash tube
Work, can be achieved the cleaning to blocking spray line in the case of without dismantling flusher, and execute-in-place is point conveniently.This spray
When spilling device installation, alignment pin is installed in dowel hole position corresponding to the adpting flange and adpting flange lid in primary cooler, avoids
The possibility of misloading occurs during installation, can make the installment work of this flusher very convenient.

Embodiment
The present invention is described in detail with reference to Figure of description, it should be noted that the implementation of the present invention is unlimited
In following embodiment.
See Fig. 1-Fig. 3, a kind of primary cooler flusher, including spray line 10, tar ammonia mixture conduit 6, backwash
Pipe 9, the lid 11 of adpting flange 19, the cleaning jet chimney 2 for being connected with steam valve 3, the cleaning ammonia water pipe for being connected with ammoniacal liquor valve 5
Road 4；It is arranged on outside primary cooler；Backwash tube 9 is arranged on the top of spray line 10, and the two is connected in the afterbody of spray line 10, spray
Spill pipe 10 and backwash tube 9 is arranged on inside primary cooler；Tar is connected between spray line 10 and tar ammonia mixture conduit 6
Ammoniacal liquor valve 7, backwash tube 9 is connected by cleaning valve 8 with cleaning jet chimney 2, cleaning ammoniacal liquor pipeline 4 outside primary cooler；
Tar ammonia valve 7 and tar ammonia mixture conduit 6 connect outside primary cooler, and backwash tube 9 passes through flange with spray line 10
Connection cover support is fixed.
See Fig. 5, Fig. 6, the adpting flange 19 of the lid 11 of adpting flange 19 and primary cooler passes through 18 spacing connection of alignment pin.Connection
The lid 11 of flange 19 is provided with the hole 17 of alignment pin 18 in the correspondence position being connected with adpting flange 19, and the hole 17 of alignment pin 18 is through hole or blind
Hole, facilitate the installation of flusher.
See Fig. 2-Fig. 4, the bottom of spray line 10 is symmetrically staggeredly provided with some sprinkling apertures 15 or some anti-blocking sprayers 16, sprinkling
The afterbody of pipe 10 sets closure plate 13 and support ring 14, and support ring 14 is fixed with primary cooler overlap joint, for supporting flusher；Closure plate 13
It can ensure that the liquid in spray line 10 and backwash tube 9 is sprayed by sprinkling aperture 15 or anti-blocking sprayer 16.Spray line 10 and recoil
Wash between pipe 9 and some supporting plates 12 are fixedly installed, strengthen the intensity of flusher.
See Fig. 1, when primary cooler internal heat exchange tubes need cleaning, tar ammonia valve 7 is opened, ammoniacal liquor valve 5, steam valve
3rd, cleaning valve 8 is turned off, and sprays tar ammonia mixture, cleaning by the sprinkling aperture 15 on spray line 10 or anti-blocking sprayer 16
Exchange heat pipe outer wall.When detection discovery spray pressure increase, illustrate that spraying aperture 15 or anti-blocking sprayer 16 blocks, and now closes
Tar ammonia valve 7, cleaning valve 8 is opened, select steam soaking or ammoniacal liquor to clean according to technological requirement, and open corresponding steam valve
Door 3 or ammoniacal liquor valve 5, steam or ammoniacal liquor enter spray line 10, sprinkling aperture 15 or anti-blocking spray to blocking by backwash tube 9
First 16 are cleaned.
The present invention can clean in the case where not stopping work to tar ammonia spray line 10.This flusher is installed
When, alignment pin 18 is installed in the position of 18 hole of alignment pin 17 corresponding to the adpting flange 19 and the lid 11 of adpting flange 19 in primary cooler, keeps away
The possibility of generation misloading during installation is exempted from, the installment work of this flusher can be made very convenient.
