Description
Technical field
Recycle small kiln cooling technique the present invention relates to a kind of coke oven chemical, specifically small kiln cooling device and its
Cooling technique.
Background technique
Currently, the method that the small kiln cooling technique of most domestic is mainly directly cooled down using interior water spray, basic technology
To be injected directly into the cooling coke of industry water into small kiln.The technical maturity is stablized, but because of coke inhomogeneous cooling, easy powdered,
Cause coke quality not high, subsequent cleaner load is big.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of small kiln cooling device and its cooling technique are provided, is improved burnt
Charcoal quality, investment is low, and the adaptation of product is strong, stable operation is flexible, environmental-friendly.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A kind of small kiln cooling device, it is characterised in that: it includes small kiln, interior water spray puddle, interior water spray pump, branch water pipe, outer
Water spray puddle, outer water spray pump, heat exchanger, the water pipe for being connected to small kiln hood, small kiln hood, mist eliminator, blower and chimney；
Water spray pump in the interior water spray puddle connection, interior water spray are connected to small kiln tail portion by branch water pipe with pump；
The outer water spray pump of outer water spray puddle connection, heat exchanger are separately connected outer water spray pump, recycle water station and be connected to small
The water pipe of kiln hood, small kiln hood are sequentially connected mist eliminator, blower and chimney.
The small kiln cooling device, it is characterised in that: the branch water pipe include flow automatic regulation water pipe and
Manually adjust the water pipe of flow.
The cooling technique of small kiln cooling device, it is characterised in that: calcined red material enters small through Dayao head feeder pipe
In kiln；
Interior water spray craft process: 0~40 DEG C of water pipe of the water through pump and six flow automatic regulations later in interior water spray puddle
It is sent with the water pipe for manually adjusting flow to the tail portion for returning small kiln；
Outer water spray craft process: circulation of 50~60 DEG C of the water pumped to heat exchanger, with circulation water station in outer water spray puddle
40 DEG C are cooled to after water heat exchange, is sent through 9 branch water pipes to the shell of small kiln, the steam generated outside cylinder, through mist eliminator
Enter blower after removing water droplet, finally drains into chimney.
The beneficial effects of the present invention are: improving, coke quality, to reduce subsequent cleaner load, synergy, investment low each
A aspect.Although the present invention adds equipment, old vacant lot is utilized, investment and land occupation are lower.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
A kind of small kiln cooling device as shown in Figure 1:, it includes small kiln 2, interior water spray puddle 3, interior water spray pump 4, branch's water
Pipe, outer water spray puddle 7, outer spray water are connected to the water pipe 10 of small kiln hood with pump 8,9, nine, heat exchanger, small kiln hood 11, catch mist
Device 12, blower 13 and chimney 14；
Water spray pump in the interior water spray puddle connection, interior water spray are connected to small kiln tail portion by branch water pipe with pump；
The outer water spray pump of outer water spray puddle connection, heat exchanger are separately connected outer water spray pump, circulation water station 15 and are connected to
The water pipe of small kiln hood, small kiln hood are sequentially connected mist eliminator, blower and chimney.
The branch water pipe includes the water pipe 5 of four flow automatic regulations and the water pipe 6 that two manually adjust flow.
The cooling technique of small kiln cooling device, calcined red material enter in small kiln through Dayao head feeder pipe 1, after cooling
Temperature of charge be about 120~160 DEG C；
Interior water spray craft process: 0~40 DEG C of water pipe of the water through pump and six flow automatic regulations later in interior water spray puddle
It is sent with the water pipe for manually adjusting flow to the tail portion for returning small kiln；
Outer water spray craft process: circulation of 50~60 DEG C of the water pumped to heat exchanger, with circulation water station in outer water spray puddle
40 DEG C are cooled to after water heat exchange, is sent through 9 branch water pipes to the shell of small kiln, the steam generated outside cylinder, through mist eliminator
Enter blower after removing water droplet, finally drains into chimney.
Its innovative point of the invention is: small kiln increases outer water injection system newly, and outer water spray and interior water spray are separated with pump.Outer water spray
Temperature increases after contacting with small kiln hood, is flow to outer water spray puddle certainly.Industry water in puddle is evacuated to by outer water spray with pump
Heat exchanger is sent cooling to small kiln after exchanging heat with recirculated water.Industry water generates steam with coke indirect heat exchange in small kiln hood,
Steam is sent to old chimney by blower after mist eliminator removes water droplet and is discharged.
Small kiln adds shell, and cooling system is made of interior water spray and outer water spray, directly cooling and indirectly cooling while carrying out,
Effectively improve coke quality.It is 1t/h that water spray, which needs water, in small kiln, and outer water spray is 55t/h.
In the above-mentioned cooling technique of the present invention: outer water spray temperature after contacting with small kiln hood increases, and outer water spray is by 0~40 DEG C
Rise to 50~60 DEG C.Outer water spray return water is sent to heat exchanger cooling, and temperature is 40 DEG C after cooling.
Relative to existing small kiln cooling technique, the advantage of the invention is that improving coke quality, reducing subsequent cleaner
Load, synergy, the low various aspects of investment.Although the present invention adds equipment, utilize old vacant lot, investment and land occupation compared with
It is low.
