Carry out ammonium hydroxide sprinkling, cleaning heat exchange pipe outer wall.However, the mixture due to using tar ammonia in actual production, leads
It causes ammonia water spraying device outlet to be frequently occluded, needs to stop work primary cooler, ammonium hydroxide spray line is disassembled and is cleared up, operate
It is inconvenient.
Invention content
In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a kind of primary cooler flusher, realizes
Tar ammonia spray line is cleaned in the case of not stopping work, is easily installed, it is easy to operate.
To achieve the above object, the utility model is achieved through the following technical solutions：
A kind of primary cooler flusher, including spray line, tar ammonia mixture conduit, spray line are mixed with tar ammonia
Tar ammonia valve is connected between conduit, tar ammonia valve and tar ammonia mixture conduit are arranged outside primary cooler；
Further include backwash tube, connecting flange lid, the cleaning jet chimney for being connected with steam valve, be connected with ammonium hydroxide valve
Cleaning ammonium hydroxide pipeline；
Backwash tube is arranged above spray line, and the two is connected in spray line tail portion, spray line and backwash tube setting
Inside primary cooler, backwash tube is connected by cleaning valve with cleaning jet chimney, cleaning ammonium hydroxide pipeline outside primary cooler；
Backwash tube is supported by flanged joint lid with spray line and is fixed.
The connecting flange of the connecting flange lid and primary cooler is limited by positioning pin and is connected.
The spray line lower part is symmetrically staggeredly equipped with several sprinkling apertures or several anti-blocking sprayers, the setting of spray line tail portion
Closure plate and support ring.
Compared with prior art, the utility model has the beneficial effects that：
The utility model can without stopping work clean tar ammonia spray line, clear without dismounting of stopping work
It washes, it is easy to operation.Backwash tube is set above spray line, and by primary cooler outside valve control spray line and backwash tube
Work, the cleaning to blocking spray line can be achieved without dismantling flusher, execute-in-place is point to facilitate.This
When flusher is installed, positioning pin is installed in the connecting flange and connecting flange lid of primary cooler corresponding dowel hole position, is kept away
The possibility for having exempted from generation misloading when installation, can make the installment work of this flusher very convenient.

Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model
Implement embodiment not limited to the following.
See Fig. 1-Fig. 3, a kind of primary cooler flusher, including spray line 10, tar ammonia mixture conduit 6, backwash
Pipe 9,19 lid 11 of connecting flange, the cleaning jet chimney 2 for being connected with steam valve 3, the cleaning ammonia water pipe for being connected with ammonium hydroxide valve 5
Road 4；It is arranged outside primary cooler；Backwash tube 9 is arranged above spray line 10, and the two is connected in 10 tail portion of spray line, spray
It spills pipe 10 and backwash tube 9 is arranged inside primary cooler；It is connected with tar between spray line 10 and tar ammonia mixture conduit 6
Ammonium hydroxide valve 7, backwash tube 9 is connected by cleaning valve 8 with cleaning jet chimney 2, cleaning ammonium hydroxide 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 that Fig. 5, Fig. 6,19 lid 11 of connecting flange and the connecting flange 19 of primary cooler limit connection by positioning pin 18.Connection
19 lid 11 of flange is provided with 18 hole 17 of positioning pin in the corresponding position being connect with connecting flange 19, and 18 hole 17 of positioning pin is through-hole or blind
