Description
Technical field
The present invention relates to production of compound fertilizer fields, and in particular to fuel gas heat recycling device in a kind of production of compound fertilizer.
Background technique
In production of compound fertilizer, many processes need discharge flue gas outward, and the flue gas discharged outward usually carries largely
Thermal energy, directly into atmosphere, on the one hand, the pollution of environment is caused, in addition, causing the waste of energy.
Summary of the invention
In conclusion in order to overcome the deficiencies of the prior art, technical problem to be solved by the invention is to provide a kind of compounds
Fuel gas heat recycling device in fertilizer production.
The technical scheme to solve the above technical problems is that flue gas heat recycling dress in a kind of production of compound fertilizer
It sets, including chimney and water pipe；The chimney is vertically installed at the position for discharging flue gas in production of compound fertilizer；At the water pipe
Heating chamber is formed in the periphery of the chimney, and between the water pipe and the chimney, is provided in the heating chamber to be added
The cold water of heat；The chimney is vertically connected with by the pipeline of multistage pyramidal structure, the both ends of the pipeline be respectively bore compared with
The big lesser serrated end of discharge end and bore, and the discharge end of next pipeline connects the contraction of a pipeline
End, thus formed inside the chimney flue gas is constantly spread after the structure shunk again；
Also horizontal inside the chimney to be equipped with several mounting boxs, the inside of each mounting box is equipped in flue gas
Driving under rotatable fan.
The beneficial effects of the present invention are: recycling the heat for discharging flue gas in production of compound fertilizer outward, and the rate of recovery
Height is conducive to environmental protection, saves the energy, reaches energy-saving and environment-friendly purpose.
Based on the above technical solution, the present invention can also be improved as follows:
Further, the fan has two blades being oppositely arranged, the thickness of each blade afterbody side towards its
The direction progressive additive in outside, and two blades are axially on same straight line, the position point of tail portion progressive additive
Other places are in axial two sides to be staggered.
Further, the upper end of the water pipe is equipped with water inlet, and lower end is equipped with water outlet.
Further, the water pipe is made of thermal insulation material.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the top view being mounted in chimney after mounting box is assembled with fan.
In attached drawing, parts list represented by the reference numerals are as follows:
1, chimney, 2, water pipe, 3, heating chamber, 4, mounting box, 5, blade.
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1, fuel gas heat recycling device in a kind of production of compound fertilizer, including chimney 1 and water pipe 2.The water pipe
2 upper end is equipped with water inlet, and lower end is equipped with water outlet, and the water pipe 2 is made of thermal insulation material.The chimney 1 is vertical
It is mounted at the position for discharging flue gas in production of compound fertilizer.The water pipe 2 is in the periphery of the chimney 1, and the water pipe
Heating chamber 3 is formed between 2 and the chimney 1, is provided with cold water to be heated in the heating chamber 3.The chimney 1 is by multistage
The pipeline of pyramidal structure is vertically connected with, and the both ends of the pipeline are respectively that the biggish discharge end of bore and bore are lesser
Serrated end, and the discharge end of next pipeline connects the serrated end of a pipeline, thus inside the chimney 1
Form the structure shunk again after constantly spreading flue gas.Flue gas in chimney 1 passes through multiple circulating repetition during chimney 1
Diffusion is shunk, and the flow path of flue gas is extended, to increase the heat exchanger time with cold water in heating chamber 3, and cigarette
Gas constantly spreads, shrinks, and alternation rushes the side wall of chimney 1, the heat of flue gas be concentrated in the side-walls of chimney 1 i.e. close to plus
The position of hot chamber 3 sufficiently improves the heat exchange efficiency of cold water in flue gas and heating chamber 3, improves the rate of recovery of flue gas heat.
As shown in Fig. 2, also horizontal inside the chimney 1 be equipped with several mounting boxs 4, each mounting box 4 it is interior
Portion is equipped with the rotatable fan under the driving of flue gas.The fan has two blades 5 being oppositely arranged.Cigarette is discharged in chimney 1
During gas, meeting driving blade 5 is rotated, and on the one hand delays residence time of the flue gas in chimney 1；In addition, flue gas is in leaf
Under the action of piece 5 rotates, moved upwards along the inner wall that tangentially against chimney 1 of the rotational plane of blade 5, so that cigarette
Gas 1 is largely focused on the inner wall of chimney 1, so that the heat in flue gas is easier in the cold water for being transferred to heating chamber 3.It is each
The thickness of a 5 tail portion side of the blade is towards the direction progressive additive on the outside of it, and two blades 5 are axial in same
On one straight line, the position (part blackened in Fig. 2) of tail portion progressive additive is respectively at axial two sides to be staggered.
By the above-mentioned design of blade 5, improve the thickness of 5 tail portion side of blade compared to other side thickness, quality also mentions
Height, to increase the inertia of 5 corresponding position of blade, so that blade 5 is in the course of rotation, tail portion is i.e. from chimney 1
The nearest position of inner wall is most strong to the effect of flue gas, is moved upwards with the inner wall for promoting more flue gases to against chimney 1, into one
Step improves heat exchanger effectiveness.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
