Detailed description of the invention
Fig. 1 is the schematic diagram of an embodiment of the present invention.
Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of flue gas waste heat recovery and cleaning device, including level-one heat exchange columns 1, secondary heat exchange tower 4, first-class heat exchanger 2, two
Grade heat exchanger 5, buffer pool 6, cleaning liquid pool 7 and pump 8,
The first-class heat exchanger 2 is set to the inside of level-one heat exchange columns 1, and one end is provided with level-one inlet tube 21, another
End is provided with level-one outlet tube 22, and the top of the level-one heat exchange columns 1 is provided with into fume pipe 11, and its underpart is detachably connected receipts
Collect slot 13, valve 12 is provided between collecting tank 13 and level-one heat exchange columns 1, the secondary heat exchanger 5 is set to secondary heat exchange tower 4
Inside, one end are provided with second level inlet tube 51, and the other end is provided with second level outlet tube 52, the top of the secondary heat exchange tower 4
It is provided with smoke evacuation tracheae 41, the level-one heat exchange columns 1 are connected to the lower part of level-one heat exchange columns 4 by fume pipe 3, the buffer pool
6 are set to the top of level-one heat exchange columns 1, and downside is connected with distribution head 62 by cleaning fluid pipe 63, and the distribution head 62 is set
It is placed in the inside of level-one heat exchange columns 1 and is located at the surface of first-class heat exchanger 2, the entrance of the pump 8 passes through pipeline and cleaning solution
Pond 7 is connected to, and outlet is connected to by pipeline with buffer pool 6.
The buffer pool 6 is additionally provided with high-pressure gas pipelines 61.
Alkaline cleaning fluid is stored in the cleaning liquid pool 7.
It is described into the first filter screen 111 is provided in fume pipe 11, the second filter screen 31 is provided in the fume pipe 3.
Particulate matter in flue gas is filtered.
As shown in Figure 1, being divided into the recycling of two-stage waste heat, had the advantage that in this way convenient for carrying out cleaning and maintenance to equipment.?
In figure, the first-class heat exchanger 2 in level-one heat exchange columns 1 is the particle for being very easy to collect in flue gas, and especially flue gas is changed in level-one
After heat, the reduction of temperature can generate new particulate matter and coagulation again, be gathered in first-class heat exchanger 2, and second level is changed
On hot device 5 then can few particulate matters collect.So only need to clean first-class heat exchanger 2 when cleaning equipment,
So that cleaning is more targeted, secondary heat exchanger 5 does not need to rinse, and reduces corrosion and damage, extends service life.
It is mostly that acid mud washes away production if being directly rinsed with tap water for what is collected in first-class heat exchanger 2
Raw acid solution can generate corrosion and damage to entire heat exchanger and heat exchange columns.In order to avoid this problem, in the first cleaning
When, it needs to deploy alkaline cleaning fluid in cleaning liquid pool 7.During flushing, acid-base neutralization, on the one hand cleaning is more thorough
On the other hand bottom prevents acidity from easily corroding equipment.
It is only ideal not enough with alkaline cleaning fluid, it is also necessary to keep the time of the first flushing quick as far as possible, can just subtract
It is few that equipment is corroded.As shown, buffer pool 6 is set to the top of level-one heat exchange columns 1, at the beginning of cleaning, pump 8 will be clear
Alkaline solution in washing lotion pond 7 is first pumped into buffer pool 6, when reaching certain storage capacity, is closed pump 8, is opened cleaning
Valve on liquid pipe road 63 makes cleaning solution quickly pass through 62 sprinkle of distribution head and is washed away in first-class heat exchanger 2.It can be with
The eroding velocity of cleaning solution is further increased by way of being passed through high pressure gas from high-pressure gas pipelines 61, reduces acid solution
To the time of the corrosion of equipment.
By washing away and then with scour without sediment motion residual liquid for alkaline solution once or twice.Valve 12 is in figure
Normally off, the opening when wanting cleaning equipment, the liquid washed away flow into collecting tank 13, after cleaning, remove collecting tank 13
Dump rinsing liquid.
It will be appreciated that the embodiments of the present invention while there has been shown and described that, for the common skill of this field
For art personnel, it is possible to understand that can be carried out to these embodiments in the case where not departing from the principles of the present invention and spirit
