Description

Flying ash sampling device

Technical field

The utility model is related to industrial technical fields, specially flying ash sampling device.

Background technology

Phosphorus content in coal-fired boiler in thermal power plant flying dust is to weigh the important indicator of boiler operatiopn and efficiency of combustion. Boiler flyash carbon content index reasonably controls the economy for being conducive to improve boiler and generating set operation in a certain range Property, cost of electricity-generating is reduced, the comprehensive utilization for expanding flyash is also helped.In order to adapt to development and the economical operation of power industry Property require, immediately sampling, immediately chemical examination, unburned carbon in flue dust on-line monitoring just become a kind of development trend.Flying ash sampling ejector It is the necessary part of boiler flyash carbon content on-Line Monitor Device.In the operational process of boiler flyash carbon content on-Line Monitor Device In, after testing after ash sample, boiler flue need to be flow back to.And be easy for occurring during this stifled ash, leakage ash, detection quartz ampoule without Phenomena such as grey.Flying ash sampling ejector is also less prone to seal, cause using electronic, mechanical structure is not only complicated, high failure rate Sampling separator cisco unity malfunction.

It is supervised online currently, disclosing a kind of boiler flyash carbon content application No. is the Chinese patent of CN200510067180.6 The flying ash sampling ejector in device is surveyed, its primary structure is that the ash discharge seat top to bottom, left and right, front and rear of flying ash sampling ejector are logical Hole, the logical quartzy detection pipe in upper hole, lower opening lead to blowback nozzle and compressed air inlet, and left and right, front and back two groups of through-hole levels are interlocked Installation and all communicated with upper lower through-hole, upper layer or so through-hole be equipped with ash discharge nozzle and ash discharge accelerating tube, ash discharge accelerating tube successively with Horizontal flapper, ash discharge nozzle, ash releasing tube and ash discharge oblique conical opening are connected, and baffle is housed on the angle in horizontal flapper;Under Through-hole is equipped with sampling nozzle and sampling accelerating tube before and after layer.Sampling nozzle one end leads to compressed air inlet, sampling accelerating tube one end Logical sampling separator.Ash ejector uses fluid mechanics principle, using compressed air as power, has ash discharge, keeps sample, locks gas, blowback Function also can avoid dust stratification, stifled ash.Although the patent solves in the operation of boiler flyash carbon content on-line monitoring system and detects stone English pipe and dust removing system it is stifled it is grey, ashless, caused by gas leakage the problems such as separator cisco unity malfunction, but structure is not light enough Ingeniously, the flying dust of high temperature enters sampler, does not carry out preliminary cooling, is easy to influence device work.

Based on this, the utility model devises flying ash sampling device, to solve the above problems.
