Description
Affiliated technical field
The present invention relates to a kind of deduster, relate in particular to a kind of sack cleaner.
Background technology
Sack cleaner is a kind of high-efficiency dust remover commonly used, but it exists major defect: the filtration resistance of deduster is big, reaches 1000～4000PA, thereby its energy consumption is big, and running expense is high; Just because of power consumption is too big, many users can not use; It also has another major defect: leaving unused in the inside and outside space of filter element, has only the filter area about 10 square metres in every cubic metre of volume, and cause the bulky of deduster, and weight is big, and cost is high; The applicant was that 012652156 patent application pilot scale figure solves these defectives at application number once, found that this scheme can't implement, though can carry out a bag inner frame, the outer skeleton of bag and cloth bag in advance, but can't this three be fitted together; If on the hard luggage, filter cloth also relaxes, the both sides of each folding folding fit together during use, and filter cloth is inoperative, so must strain, this scheme can't be strained.
Summary of the invention
How energy-conservation sack cleaner is, at first should be supported with proofs, and its principles of science is:
Can know that by dynamics the kinetic energy of material is:
T＝mv
2/2 ………………………………………………(1)
In the formula: the kinetic energy that T-material had; The quality of m-material; The movement velocity of v-material.
This formula is interpreted as the energy that gas consumed that is processed, and wherein m is a gaseous mass, and v is a flowing velocity.
Find out in the formula, square being directly proportional of the kinetic energy that material had and its movement velocity, and speed v can change and control artificially, when v drops to three/for the moment, its energy then drops to 1/9th.Energy-conservation theoretical principle and the foundation of sack cleaner that Here it is.
Use sack cleaner, must apply kinetic energy to gas, with the form of gas it is filtered by force through filtrate flue dust with blower fan; Clean air passes filtrate and enters atmosphere; Dust is retained down, and gas is wanted consumed energy in the process of filtering, and the kinetic energy of gas comes from blower motor.When the kinetic energy of controlling gas artificially descends it significantly, then the power consumption of power source also will decline to a great extent thereupon, and reach the purpose of energy savings.In the dust pelletizing system, under the prerequisite that guarantees the processing air quantity, the kinetic energy of gas depends on the total head of blower fan, and the numerical value of blower fan total head depends on the resistance of dust pelletizing system, and the resistance of deduster then depends on the resistance of filtrate.Handle air quantity, gas just must flow, and also just certainly exists wind speed; Have wind speed in the dust pelletizing system, its SR also just inevitable with square being directly proportional of flowing velocity, filtrate is no exception.
V in (1) formula is changed, and making other is constant c; When v=1, T=1c; During v=3, T=9c; During v=1/3, T=c/9; Be that the rate of filtration drops to three/for the moment, the energy consumption of filtrate is that resistance just drops to 1/9th.The rate of filtration drops to 1/3rd method and has only one: the processing air quantity on the unit are is reduced to 1/3rd.For example: be used for handling 10,000 m
3The filter area of/h air quantity is by 100m
2Be increased to 300m
2Total blast volume is constant, and the air quantity that unit are is handled has dropped to 1/3rd, and the rate of filtration has just dropped to 1/3rd, and filtering material resistance at this moment just drops to 1/9th, just can realize reducing resistance and purpose of energy saving.
By routine, filter area is increased to three times, and its production cost, weight, volume also will be increased to three times, and this can not take.Only way only under constancy of volume or littler and prerequisite that production cost does not increase, is increased to three times even more with filter area.
