Abstract
A detachable combined water tube waste heat boiler is a waste heat recovery device for coal gas or blowing gas in a small nitrogen fertilizer plant. It has the advantages of small resistance, high thermal efficiency, long service life, investment saving, etc., and is characterized in that; the shell (2) is provided with orifices (24) corresponding to the heat exchange unit (1), and the periphery of the orifices (24) is provided with a fixed flange (5); the water inlet pipe (13) and the water outlet pipe (11) are arranged on the same side of the heat exchange unit (1) and are connected with the flange cover (12) into a whole through welding or a filler sealing component. When the heat exchange unit (1) is replaced, only the relevant bolts and nuts need to be disassembled, and gas cutting and electric welding do not need to be used, so that the possible explosion accidents caused by 'fire striking' are fundamentally avoided.
Description
The utility model is that small nitrogenous fertilizer plant reclaims coal gas (or blowing-out gas) waste heat waste heat boiler.
The little nitrogenous fertilizer of China is born three during the last ten years, and fire tube monoblock type waste heat boiler is adopted in coal gas (or blowing-out gas) waste heat recovery always.This waste heat boiler resistance is big, the life-span is short, the thermal efficiency is low, investment is high.(see the patent No.: 91211345.6) above-mentioned shortcoming is overcome, following blemish in an otherwise perfect thing is still arranged though occurred " combined type water pipe waste heat boiler " in recent years.Promptly several heat exchange units because of " combined type water pipe waste heat boiler " are inclusive in the non-disconnectable housing, in case certain heat exchange unit breakage when changing, just must be cut housing with gas cutting.After heat exchange unit is upgraded, must mend with the electric weld handle housing again.This not only causes changes the complicated of heat exchange unit, the more important thing is, just in case System Security Measures is inconsiderate, can set off an explosion because of " getting angry " operation of gas cutting, electric welding.
The purpose of this utility model provides a kind of improved knockdown type combined type water pipe waste heat boiler.It both possessed all advantages of " combined type water pipe waste heat boiler ", can not need " getting angry " just can realize the replacing of heat exchange unit easily again.To avoid the generation of explosion accident.
For achieving the above object, the utility model adopts three measures: 1, the position corresponding to each heat exchange unit is provided with aperture and mounting flange on housing; 2, water inlet pipe, the outlet pipe of heat exchange unit are located at its homonymy; 3, add at water inlet pipe, the outlet pipe place of heat exchange unit not only match with mounting flange, but also with the relatively-stationary blind flange of heat exchange unit.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings is as follows:
Fig. 1 is a knockdown type combined type water pipe waste heat boiler schematic diagram.
Fig. 2 is the A-A cutaway view of Fig. 1.
1 is heat exchange unit; 2 is housing; 3 is bolt; 4 is nut; 5 is mounting flange; 6 is tedge; 7 is drum; 8 is down-comer; 9 is the total header of upper connecting tube; 10 is valve; 11 is outlet pipe; 12 is blind flange; 13 is water inlet pipe; 14 is valve; 15 is the total header of lower linking tube; 16 is ash bucket; 17 is supporting steel; 18 is ash-removing valve; 19 is supporting leg; 20 are the dedusting tube; 21 is filler strip; 22 is the gas entry pipe; 23 is gas outlet tube; 24 is the aperture.
Housing (2) is the drum ladle that forms with welded steel plate.Corresponding to the residing position of each heat exchange unit (1), be provided with the aperture (24) that confession is packed into or shifted out heat exchange unit (1) on it.Its aperture (24) is provided with mounting flange (5) all around.
Heat exchange unit (1) is the core parts that waste heat boiler is realized the coal gas waste heat recovery.Its water inlet pipe (13), outlet pipe (11) be located at respectively its homonymy bottom and topmost.
Blind flange (12) is a flat shape blind plate that matches with mounting flange (5).It connects with water inlet pipe (13), the outlet pipe (11) of heat exchange unit (1) mutually by welding (or packing seal assembly---not shown), and four is an integral body.
When heat exchange unit (1) desire row is changed, as long as taking off valve (14) and valve (10) goes up the bolt of close water inlet pipe (13), outlet pipe (11) side, screws off nut (4), just blind flange (12), heat exchange unit (1) and water inlet pipe (13) thereof, outlet pipe (11) can be shifted out in the lump.After treating the whole spare part of new heat exchange unit (1), water inlet pipe (13), outlet pipe (11) and blind flange (12) packed into, the bolt on fastening nut (4) and valve (14), the valve (11) gets final product again.
In view of the utility model, when changing heat exchange unit (1), need to cut benefit housing (2) with gas cutting, electric welding.Thereby, the advantages such as the thermal efficiency is high, the life-span is long, reduced investment little except that resistance with " combined type water pipe waste heat boiler ", also have replacing heat exchange unit (1) tube list, convenience, save time, and the advantage of fundamentally having avoided causing because of " getting angry " explosion accident.
Present small nitrogenous fertilizer plant, desire adopts the utility model, for using " combined type water pipe waste heat boiler " person, can be transformed by this structure on the basis of former waste heat boiler; For still using fire tube monoblock type waste heat boiler person, can be under the constant situation of original drum (7), tedge (6), down-comer (8), add a total header of lower linking tube (15) and a total header of upper connecting tube (9) more afterwards, with this knockdown type combined type water pipe waste heat boiler former fire tube monoblock type waste heat boiler being replaced gets final product.
Claims (1)
1, a kind of knockdown type combined type water pipe waste heat boiler that is used for small nitrogenous fertilizer plant coal gas or waste heat recovery device for blowoff gas, it has housing (2), heat exchange unit (1), the total header of upper connecting tube (9), the total header of lower linking tube (15), tedge (6), down-comer (8), drum (7), it is characterized in that:
(a): on housing (2),, aperture (24) is set and around it, is provided with mounting flange (5) corresponding to the residing position of each heat exchange unit (1);
(b): the water inlet pipe (13) and the outlet pipe (11) of heat exchange unit (1) are located at its same side;
(c): blind flange (12) connects with water inlet pipe (13), the outlet pipe (11) of heat exchange unit (1) mutually by welding or packing seal assembly, and four is an integral body.
