Abstract
The invention discloses a kind of methods for improving gas preheater service life and efficiency, it include: the access path that one is opened in the middle part of the entry and exit of gas preheater, so that entire gas preheater is separated into two relatively independent parts, while multiple manholes are arranged in access path；High pressure water flushing is carried out in the entry and exit of gas preheater and access path by giant；The heat pipe easily corroded by lower part in access path gas preheater carries out maintenance replacement in time.Method of the invention can largely thoroughly remove the stronger sundries of the adhesivenesses such as dust on gas preheater, and reduce labor intensity, to improve the efficiency of gas preheater, reduce flue gas loss, reduce boiler operatiopn cost, create benefit.
Description
Technical field
The present invention relates to a kind of methods for improving gas preheater service life and efficiency.
Background technique
Baogang is dynamic to be equipped with gas preheater for head factory 8#9# gas boiler, using fume afterheat come heating gas；?
When mixing the gaseous mixture of burn the grass on waste land coke-stove gas and blast furnace gas, since impurity is excessive in coke-stove gas, the product after leading to burning is big
Amount is collected on gas preheater heat pipe, so that gas preheater efficiency decline 80%, service life reduction 60%, while coal gas is pre-
The increase of hot device pressure difference reduces boiler load, influences the economical operation of boiler, traditional approach can only be to gas preheater surface into
Horizontal high voltage water rinses, and due to heat pipe excessive height and is to be staggered in arrangement, and cleaning is not clean, ineffective.
Summary of the invention
In order to solve the above-mentioned technical problem, the object of the present invention is to provide a kind of raising gas preheater service life and efficiency
Method.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A method of improving gas preheater service life and efficiency, comprising:
1) one access path is opened in the middle part of the entry and exit of gas preheater, so that entire gas preheater is separated into
Two relatively independent parts, while multiple manholes are arranged in access path；
2) high pressure water flushing is carried out in the entry and exit of gas preheater and access path by giant；
3) heat pipe easily corroded by lower part in access path gas preheater carries out maintenance replacement in time.
Further, the diameter of the access path is 1m.
Compared with prior art, advantageous effects of the invention:
This method setting is simple, and investment is low, only 1.0 meters of access path need to be opened in aperture in the middle part of electric gas preheater
, work when clearing up gas preheater simple, high-efficient, cleaning is thorough.After the completion of transformation, lower part is easily corroded
Heat pipe, it is also convenient to check in time in use, carry out maintenance replacement.
Entry and exit high pressure water cleaning, while high pressure water cleaning can be used above and below in 1.0 meters of access path mouths, then exist
Outlet cleaning sweeps away the sundries such as dust, the sulfate come, works when clearing up gas preheater simple, high-efficient, and cleaning is thorough.
Detailed description of the invention
Fig. 1 is the setting schematic diagram of access path.
Description of symbols: 1- access path.
Specific embodiment
A method of improving gas preheater service life and efficiency, comprising:
1) as shown in Figure 1, opening one access path 1 in the middle part of the entry and exit of gas preheater, so that entire coal gas is pre-
Hot device is separated into two relatively independent parts, while 4 manholes are arranged in access path 1；
2) high pressure water flushing is carried out in the entry and exit of gas preheater and access path by giant；
3) heat pipe easily corroded by access path 1 to lower part in gas preheater carries out maintenance replacement in time.
It is stronger that the above method through the invention can largely thoroughly remove the adhesivenesses such as the dust on gas preheater
Sundries, reduce labor intensity, to improve the efficiency of gas preheater, reduce flue gas loss, reduce boiler operatiopn at
This, creates benefit.After this method, since gas preheater no longer blocks, boiler load is influenced, separate unit boiler every year may be used
To create about 3,960,000 yuan of profit.
Embodiment described above is only that preferred embodiment of the invention is described, and is not carried out to the scope of the present invention
It limits, without departing from the spirit of the design of the present invention, those of ordinary skill in the art make technical solution of the present invention
Various changes and improvements, should all fall into claims of the present invention determine protection scope in.
Claims (2)
1. a kind of method for improving gas preheater service life and efficiency characterized by comprising
1) one access path is opened in the middle part of the entry and exit of gas preheater, so that entire gas preheater is separated into relatively
Independent two parts, while multiple manholes are arranged in access path；
2) high pressure water flushing is carried out in the entry and exit of gas preheater and access path by giant；
3) heat pipe easily corroded by lower part in access path gas preheater carries out maintenance replacement in time.
2. the method according to claim 1 for improving gas preheater service life and efficiency, which is characterized in that the maintenance is logical
The diameter in road is 1m.
