Description
technical field:
The utility model relates to smoke sampling technical field, refers in particular to a kind of flue gas sampling device of electrical heating type band automatic protection functions.
background technology:
Along with the rapid growth of Electricity Demand, power plant soot total amount keeps rapid growth trend.How accurately and effectively benzene in coal fire discharged flue gas, naphthalene, particle equal size occupy the great majority of anthropogenic discharge, the content of gather and analysis flue gas benzene, naphthalene, particle, become the important method evaluating the existing pollutant catabolic gene equipment in coal-burning power plant.To flue gas run continuous samples analyze time, although existing sampler possesses heat insulation function, but because outdoor temperature is low, sampling line is long, dew condensation phenomenon is there is when causing flue gas to enter analytical equipment, and due to the water-soluble rear formation acid solution of corrosive gas, easily corrosion is produced to sampler, benzene, naphthalene, particles etc. easily block probe when condensation, cause sampler cannot continuous sampling work, especially in the winter that day and night temperature is larger, the blocking that condensation causes, corrosion phenomenon is particularly evident, but also there is sampling location complicated operation, sampling cost is high, collecting efficiency is low, deviation is large.
utility model content:
The purpose of this utility model is to overcome the deficiency existed in above-mentioned technology, provides a kind of flue gas sampling device of electrical heating type band automatic protection functions.The utility model purport solves sampler blocking in the mode of low cost and prevents the problem of flue gas corrosion.
The purpose of this utility model realizes as follows: a kind of flue gas sampling device of electrical heating type band automatic protection functions, comprise sampler barrel, sampler barrel is provided with air admission hole and thief hole, described sampler barrel inside is provided with circular baffle plate, circular baffle plate surrounding is uniformly distributed fixing muscle, and fixing muscle welding is with on sampler barrel inwall, described air admission hole port part is provided with filtrator, another port and sampler barrel inner space, and port is provided with temperature sensor, temperature sensor is by wire connection signal converter, signal converter connects PLC, PLC connects sky and opens, sky drives the well heater connecting and be positioned at sampler barrel inside, well heater is fixed on the sealing socket of sampler barrel rearward end, well heater connects contactor, sensor is protected in contactor connection, protect sensor connection sky to open, when flue-gas temperature reaches capping value, well heater stops heating automatically, when temperature return preset lower limit, well heater control loop is communicated with beginning Automatic-heating.
Described signal converter, PLC, sky are opened, protect sensor and contactor is positioned at electric cabinet.
Described sampler barrel outer wall is provided with heat-insulation layer.
Described baffle plate is positioned at thief hole rear.
The beneficial effects of the utility model are: reasonable in design, be skillfully constructed novelty, well heater heats the flue gas entering into sampler barrel inner chamber, prevent flue gas from probe, producing dew condensation phenomenon and cause sampler that corrosion and blocking occur, the sampling of guarantee sampler work is undistorted, continuation and serviceable life; The large solid entering into the flue gas of sampler barrel inner chamber can filter by the filtrator of air admission hole port, greatly reduces flue gas and enters the possibility resulted in blockage after in sampler barrel chamber; Baffle plate can increase the distance of flue, prevents flue gas cool-down too fast, and easily runs off; Realize Automatic-heating by PLC, ensure to there will not be dew condensation phenomenon in sampler barrel, and protect sensor and can play effect effect to overheating protection, preventing from having no progeny in sample gas, dry combustion method is overheated causes fire failure, achieves Automated condtrol.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
embodiment:
With reference to Fig. 1, a kind of flue gas sampling device of electrical heating type band automatic protection functions, comprise sampler barrel 4, sampler barrel 4 is provided with air admission hole 6 and thief hole 1, described sampler barrel 4 inside is provided with circular baffle plate 16, circular baffle plate 16 surrounding is uniformly distributed fixing muscle 2, and fixing muscle 2 welds with on sampler barrel 4 inwall; Described air admission hole 6 port part is provided with filtrator 5, another port and sampler barrel 4 inner space, and port is provided with temperature sensor 7, temperature sensor 7 is by wire connection signal converter 10, signal converter 10 connects PLC 11, PLC 11 connects sky and opens 13, sky drives the well heater 8 that 13 connections are positioned at sampler barrel 4 inside, well heater 8 is fixed on the sealing socket 9 of sampler barrel 4 rearward end, well heater 8 connects contactor 15, contactor 15 connects and protects sensor 14, protects sensor 14 and connects sky and open 13.Described signal converter 10, PLC 11, sky open 13, protect sensor 14 and contactor 15 is positioned at electric cabinet 12.Described sampler barrel 4 outer wall is provided with heat-insulation layer 3.Described baffle plate 16 is positioned at thief hole 1 rear.
Sampler barrel 4 is fixed in sampling environment by sealing socket 9; flue gas is through filtrator 5 and flow into sampler barrel 4 inner chamber by air admission hole 6; and carry out inner chamber temperature signal collection by temperature sensor 7; the simulating signal of collection is become digital signal by signal converter 10 and is sent to PLC 11; PLC 11 controls the well heater 8 that sky opens 13 connections; when well heater 8 own temperature is too high by contactor 15 with protect sensor 14 and protect self, opens 13 by sky and cut off the electricity supply.
The utility model reasonable in design, be skillfully constructed novelty, well heater 8 heats the flue gas entering into sampler barrel 4 inner chamber, prevent flue gas from probe, producing dew condensation phenomenon and cause sampler that corrosion and blocking occur, the sampling of guarantee sampler work is undistorted, continuation and serviceable life; The large solid of the flue gas entering into sampler barrel 4 inner chamber can filter by the filtrator 5 of air admission hole 6 port, greatly reduces flue gas and enters the possibility resulted in blockage after in sampler barrel 4 chamber; Baffle plate 16 can increase the distance of flue, prevents flue gas cool-down too fast, and easily runs off; Realize Automatic-heating by PLC 11, ensure to there will not be dew condensation phenomenon in sampler barrel 4, and protect the effect that sensor 14 can play overheating protection, preventing from having no progeny in sample gas, dry combustion method is overheated causes fire failure, realizes Automated condtrol.
