Abstract
The utility model relates to a kind of improved reformation hydrogen compressors of naphtha catalytic reforming unit.Mainly solve the problems, such as that the existing higher energy loss of compressor surplus capacity is bigger.It is characterized by: compressor main body (1) both ends are cylinder block (5), each cylinder block (5) is equipped with cylinder head (2)；Each on the inside of cylinder head (2) to increase cylinder clearance adjustment flange (3), adjustment flange (3) side is boss, and the other side is groove, and surrounding is provided with bolt hole.The improved reformation hydrogen compressor of the naphtha catalytic reforming unit can reduce compressor original state capacity, reduces compressor shaft power loss, saves the energy, slow down the defective modes such as compression cover side liquid hammer.
Description
Technical field
The utility model relates to Petro-Chemical Machinery technical field, in particular to a kind of naphtha catalytic reforming unit transformation
Reformation hydrogen compressor afterwards.
Background technique
Compressor used in oil plant is typically all that electric energy or other forms can be converted to mechanical energy, then turned by mechanical energy
Be changed in gas pressure can a kind of power device, be a kind of low-pressure gas to be promoted to high pressure gas by compression to meet
The driven fluid machinery of petroleum and petrochemical industry manufacturing technique requirent, compressor can be divided into reciprocating (piston type) by its working principle and press
Contracting machine, rotary (rotary) compressor (turbine type, liquid-ring type, turbine) compressor, Axial Flow Compressor, injecting type compressor
And the various types such as helical-lobe compressor, wherein what is be most widely used in petrochemical industry is reciprocating (piston type) compressor.It urges
Changing reformer to reform hydrogen compressor form is reciprocating-piston compressor, and compressed media is reformer hydrogen, admission pressure
For 1.2Mpa, pressure at expulsion 1.8Mpa.When because of compressor type selecting, rated discharge amount is all larger than the actually required exhaust of technique
Amount；Now according to existing reformer process conditions, the actually required discharge capacity of compressor is calculated, is arranged further according to compressor rated designs
Meter calculates superfluous capacity；Superfluous capacity is higher to cause compressor shaft power loss bigger, wastes a large amount of electric energy.It is easy
Increase slows down the defective modes such as the compression cover side liquid hammer.
Summary of the invention
Technical problem to be solved in the utility model is to overcome existing compressor surplus exhaust present in background technique
The bigger problem of higher energy loss is measured, and a kind of improved reformation hydrogen compressor of naphtha catalytic reforming unit is provided, it should
The improved reformation hydrogen compressor of naphtha catalytic reforming unit can reduce compressor original state capacity, reduce compression
Shaft power loss, saves the energy, slows down the defective modes such as compression cover side liquid hammer.
The invention for solving the technical problem can reach by following technical solution: naphtha catalytic reforming unit transformation
Reformation hydrogen compressor afterwards, including compressor main body, the compressor main body both ends are cylinder block, and each cylinder block is equipped with cylinder
Lid；It is each on the inside of cylinder head to increase a cylinder clearance adjustment flange；Adjustment flange side is boss, and the other side is groove, surrounding
It is provided with bolt hole.
The cylinder head and adjusting method your beautiful writings are equipped with gasket；The adjustment flange material is 45# steel forgings.
The improved reformation hydrogen compressor working principle of the naphtha catalytic reforming unit are as follows:
By following formula it is found that compressor original state capacity and the shaft power of compressor are proportional:
Wherein:
Wi--- compressor shaft power, kW；
The adiabatic coefficent of K --- medium；
Z1, Z2 --- the gas compressibility factor under the conditions of compressor inlet and outlet；
P1 --- admission pressure, MPa；
QV --- compressor original state capacity, m3/min；
ε --- inlet and outlet compression ratio.
Method by increasing compresser cylinder clearance volume, reduces compressor original state capacity, that is, meets technique
Requirement, and compressor actual power is reduced again, achieve the purpose that save electric energy.
The utility model can be had the following beneficial effects: compared with above-mentioned background technique using the naphtha catalytic reforming
Reformation hydrogen compressor before plant modification, the practical shaft power of highest are 296.55KW, and average shaft power is 277.31KW；Using this
After technology, the practical shaft power of highest is 257.4KW, and average shaft power is 237.15KW, greatly reduces compressor shaft power damage
It loses, saves the energy, while slowing down the defective modes such as compression cover side liquid hammer.It is expected that the Spring Festival holidays save electric energy 351802kWh, saving takes
With about 211081 yuan.
Detailed description of the invention
Attached drawing 1 is the system structure diagram of the utility model；
Attached drawing 2 is the structural schematic diagram of the utility model adjustment flange.
In figure: 1, compressor main body, 2, cylinder head, 3, adjustment flange, 4, gasket, 5, cylinder block.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawing:
As shown in attached drawing 1, Fig. 2, the improved reformation hydrogen compressor of the naphtha catalytic reforming unit, including compression owner
Body 1,1 both ends of compressor main body are cylinder block 5, and each cylinder block 5 is equipped with cylinder head 2, increases by one on the inside of the cylinder head 2
A cylinder clearance adjusts flange 3, it acts as increasing compressor two-stage cylinder head side clearance volume, thus reduce compressor inhale,
Capacity；The specification for adjusting flange need to be according to designs such as the original clearance volume of compresser cylinder, cylinder dimensions, superfluous loads
The corresponding compressor redundant gap adjusts component out；Gasket 4 is respectively provided between the cylinder head 2, cylinder block 5 and adjustment flange 3；It adjusts
Whole 3 side of flange is boss, and the other side is groove, and surrounding is provided with bolt hole, is fixed on cylinder head 2 for that will adjust flange 3；
Adjustment 3 material of flange is 45# steel forgings.
After blue stone Co., Ltd implements the present invention to reformer reformation hydrogen compressor C401A in grand celebration, in technique
Under the constant operating condition of load, maximum current is 41.25A, average current 39.56A before being transformed；Maximum current is after transformation
37.5A, average current 36.08A.Reduce motor actual current 3.48A.Compressor shaft power is by Zhou Pingjun shaft power after transformation
237KW is dropped to by 277KW, averagely reduction 40KW；It is expected that the Spring Festival holidays save electric energy 351802kWh, about 211081 yuan are saved money.
Meet technique requirement, and play energy-saving effect, reaches invention effect.
