Abstract
The utility model relates to a kind of dust leakage detection apparatus of many casings fly-ash separator, be connected to and dusty gas is purified, there is the air outlet place of many casings fly-ash separator of at least one independent air outlet, comprise the air outlet place that is arranged on many casings fly-ash separator and will introduce on-line detector in air-flow and carry out the gas pipeline to be detected of dust concentration detection, be connected to the dust concentration detector of gas pipeline end to be detected, the induced draft fan be connected with dust concentration detector successively, main air blower and aiutage.Compared with prior art, the utility model can adopt the fuel gas and dust concentration of separate unit detector to each tank outlet of many casings fly-ash separator to carry out on-line checkingi.
Description
Technical field
The utility model relates to field of Environment Protection, especially relates to a kind of dust leakage detection apparatus of many casings fly-ash separator.
Background technology
Along with improving constantly of national environmental standard and dust pelletizing system monitoring requirement, increasing house outlet sets up the on-line monitoring leakage detection apparatus of dust concentration.Dust concentration monitoring leakage detection apparatus common is at present arranged as follows:
The first, to the fly-ash separator of operation under positive pressure as blast furnace gas dust collector, in the outlet of its each casing, a dust concentration on-line computing model is all set;
The second, to most environmental dust removal devices that negative pressure is run, the aiutage after main air blower thereafter arranges a dust concentration on-line computing model.
For first kind of way, although can monitor continuously the dust concentration that each dust-removing box exports, buy and safeguard that the cost of on-line detector increases many times; Although only establish an on-line detector to the second way, buy and maintenance cost lower, cannot the dust-removing box that dust concentration exceeds standard be positioned, increase check cost.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of dust leakage detection apparatus adopting the fuel gas and dust concentration of separate unit detector to each tank outlet of many casings fly-ash separator to carry out many casings fly-ash separator of on-line checkingi is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A dust leakage detection apparatus for many casings fly-ash separator, is connected to and purifies dusty gas, has the air outlet place of many casings fly-ash separator of at least one independent air outlet, comprising:
The air outlet place being arranged on many casings fly-ash separator carries out the gas pipeline to be detected of dust concentration detection by introducing on-line detector in air-flow,
Be connected to the dust concentration detector of gas pipeline end to be detected,
The induced draft fan be connected with dust concentration detector successively, main air blower and aiutage.
The air outlet place of described many casings fly-ash separator is also provided with the switch valve each tank outlet dust concentration being carried out to on-line checkingi or continuous on-line detection in turn.
The air outlet fuel gas and dust concentration limit of described many casings fly-ash separator is 10 ~ 30mg/Nm
3.
Described many casings fly-ash separator also connects the import of main air blower by main air blower inlet pipeline.
Described dust concentration detector is directly installed on the ground.
Compared with prior art, the fraction in each tank outlet air-flow is introduced the detection that dust concentration detector carries out dust concentration by induced draft fan by the utility model, and contrasts with the limit value of setting, leaks grey phenomenon to judge whether to have in each casing.And by switch valve, can realize separate unit detector to all tank outlet fuel gas and dust concentration detects, simultaneously because gas flow to be checked greatly reduces, the detector of small dimension can be adopted, greatly save the cost of investment of dust concentration detection system; And for depression dust-removing system, the installation site of dust concentration detector can be down on ground by the high-altitude on aiutage top, greatly facilitates the maintenance of detector.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 be many casings fly-ash separator, 2 be switch valve, 3 be gas pipeline to be detected, 4 be dust concentration detector, 5 be induced draft fan, 6 be main air blower intake stack, 7 be main air blower, 8 for aiutage.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of dust leakage detection apparatus of many casings fly-ash separator, its structure as shown in Figure 1, be connected on many casings fly-ash separator 1, mainly comprise switch valve 2, gas pipeline to be detected 3, dust concentration detector 4, induced draft fan 5, main air blower inlet pipeline 6, main air blower 7 and aiutage 8.
The many casings fly-ash separator 1 pair of dusty gas connected purifies, and has of independent air outlet with upper box, and the Chinese Industrial Standards (CIS) of its exit gas dust concentration limit value is≤10 ~ 30mg/Nm according to the difference of region and technique
3.Switch valve 2 is located on each casing air outlet gas pipeline 3 to be detected, by the action in turn of switch valve 2, can realize the on-line checkingi in turn of each tank outlet dust concentration; Simultaneously also by the control to switch valve, realize the continuous on-line detection to specific tank outlet dust concentration.Sub-fraction in each tank outlet air-flow can be introduced the detection that dust concentration detector 4 carries out dust concentration by gas pipeline 3 to be detected, when house outlet fuel gas and dust concentration exceedes the limit value of setting, while display dust concentration value, carry out the warning that exceeds standard.The bootable air-flow to be checked of induced draft fan 5 enters main air blower 7 import.Main air blower 7 is one of topmost equipment in whole device, dust-contained airflow can be introduced fly-ash separator purification, main air blower 7 also connects many casings fly-ash separator 1 by main air blower inlet pipeline 6, and fly-ash separator purified gas is discharged by the aiutage 8 after being arranged on main air blower 7.
The utility model in use, the gas to be detected taken out from each casing of many casings dedusting 1 enters dust concentration detector 4 through switch valve 2 and gas pipeline to be detected 3, then delivered to the inlet pipeline 6 of main air blower 7 by induced draft fan 5, finally discharge through aiutage 8 together with primary air.
By the switch of each switch valve 2, gas to be checked for each tank outlet can be caused detector 4 and carry out dust concentration detection, and the limit value of measured value and setting is contrasted, then judge whether each casing has and leak grey phenomenon.
