Description
Technical field
The invention belongs to intermediate level liquid waste Cemetation process fields, and in particular to a kind of pulverized fuel ash cement object
Batch can blows bl bridge layer and method.
Background technique
Intermediate level liquid waste Cemetation engineering waste liquid flow and solid stream amount are wherein vital two
Control parameter.Evaluation solidify one of fine or not standard of weight --- and the ratio of mud is exactly waste liquid flow and consolidates stream amount (or waste liquid
Cumulative amount and expect cumulative amount admittedly) the ratio between.In solid stream amount control system, Gu the quality of stream amount control system, directly reflects
Whether it is capable of the operation of continuous-stable to solid material flow system, is also related to whether solid stream amount controls in given value, while
It is related to the ratio of mud whether control system controlled level reaches control.In casting operational process in the past, admittedly expect flowed fluctuation
Larger (up to 8%), post operation personnel, which will ceaselessly operate, blows bridge formation pressure sky, controls its pressure, in operation,
Sometimes pressure open very stream amount does not always reach requirement admittedly greatly, pressure very little and solid stream amount is very big, is difficult to realize sometimes
Compared with stability contorting, or even process control needs are not achieved.Therefore urgently process flow is simple in exploration one, and application cost is low, effect
The high treatment process of rate is to realize the problems such as adjusting to solid stream amount.
Summary of the invention
It is an object of the invention to: a kind of pulverized fuel ash cement material pot blows bl bridge layer, and it is solid to solve large volume pouring cement
Change material flow control admittedly 3% hereinafter, to improve the stability of solid stream amount.
Technical scheme is as follows: a kind of pulverized fuel ash cement material pot blows bl bridge layer, including air accumulator, air accumulator
It is separately connected control valve A and control valve B, blows bridge formation A in control valve A connection cement bin A, in control valve B connection cement bin B
Blow bridge formation B；And cement bin A passes through outlet valve A with cement bin B respectively and connect auger with outlet valve B, lower section is equipped with nucleon and claims
Flowmeter, and between auger connection stirred tank.
The auger is L-type.
A kind of method that pulverized fuel ash cement material pot blows bl bridge layer, comprising the following steps:
S1: opening control valve A, control valve B, opens outlet valve A, outlet valve B, starts auger；Air accumulator is supplied；
S2: the flow that nucleon claims flowmeter is adjusted；
S3: cement bin A, cement bin B pressure are adjusted by control valve A, control valve B；
S4: cement bin A, after the cement in cement bin B is blown bridge formation, blows bridge formation B purging, through outlet valve A, outlet valve B and
Auger is transported between stirred tank；
In the S2, the flow for adjusting nucleon flowmeter is referred to as 11T/h~14T/h.
Cement bin A, cement bin B pressure are adjusted in 0.4kPa~15kPa by control valve A, control valve B.
Remarkable result of the invention is: reducing influence of the pressure to cement bin blanking, solution is exactly to replace two
It is a to blow bridge formation, to avoid bridging in cement bin and clogging, admittedly material flow control is 3% hereinafter, improving solid stream amount
Stability, this work have been resolved.
Detailed description of the invention
Fig. 1 is that pulverized fuel ash cement material pot of the present invention blows bl bridge layer schematic diagram；
Fig. 2 blows bl bridge layer for pulverized fuel ash cement material pot of the present invention and blows bridge formation schematic diagram；
In figure: blow bridge formation A1, cement bin A2, outlet valve A3, control valve A4, air accumulator 5, nucleon claim flowmeter 6, auger 7,
8 between stirred tank, control valve B9, blow bridge formation B10, cement bin B11, outlet valve B12
Specific embodiment
A kind of pulverized fuel ash cement material pot blows bl bridge layer, including air accumulator 5, air accumulator 5 be separately connected control valve A4 with
Bridge formation A1 is blown in control valve B9, control valve A4 connection cement bin A2, blows bridge formation B10 in control valve B9 connection cement bin B11；
And cement bin A2 passes through outlet valve A3 with cement bin B11 respectively and connect auger 7 with outlet valve B12, auger 7 is L-type, lower section peace
Claim flowmeter 6 equipped with nucleon, and auger 7 is connected to 8 between stirred tank.
A kind of pulverized fuel ash cement material pot blows bridging method, comprising the following steps:
S1: opening control valve A4, control valve B9, opens outlet valve A3, outlet valve B12, starts auger 7；Air accumulator 5 carries out
Gas supply；
S2: the flow for adjusting nucleon flowmeter 6 is referred to as 11T/h~14T/h；
S3: cement bin A2, cement bin B11 pressure are adjusted in 0.4kPa~15kPa by control valve A4, control valve B9；
S4: cement bin A2, after the cement in cement bin B11 is blown bridge formation 1, blows bridge formation B10 purging, through outlet valve A3, go out
Material valve B12 and auger 7 are transported to 8 between stirred tank；
Bridge formation, which is blown, by operation wall built-up or blocking warehouse occurs to avoid storehouse inner wall, it is unstable so as to cause cement bin blanking
Existing phase, eliminate original blows influence of the bl bridge layer to warehouse blanking, material is at the uniform velocity to auger ash conveying cement.
