Description
Technical field
The utility model belongs to energy-conserving and environment-protective field, relates to emission measurement, is specifically related to a kind of hot stopple coupon of companion measured for boiler near-zero release.
Background technology
Regulation in " fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011), general regional coal-burning boiler chimney soot emissions limit value 30mg/Nm
3, key area coal-burning boiler chimney soot emissions limit value 20mg/Nm
3, mercury and mercuric compounds pollutant emission limit 0.03mg/Nm
3.
Experimentally dust concentration is analyzed at 20mg/Nm in room
3flue gas in, the particle of equivalent diameter below 10 microns (PM10) accounts for the mass ratio more than 90% of all dust.Existing thermal power plant is substantially all furnished with wet desulphurization device before chimney, and the flue gas therefore entering smoke stack emission is supersaturation wet flue gas.Containing a large amount of gasoloid and fine liquid water droplet in supersaturation wet flue gas.The particle of equivalent diameter below 10 microns (PM10) has and much sticks on gasoloid and fine liquid water droplet.
At present, in boiler emission sampling detects, stopple coupon is directly exposed in air.Because environment temperature is less than flue-gas temperature, gasoloid and fine liquid water droplet can condense in sampling tube wall and form bulky grain water droplet, cannot enter sample collection device, thus cause detection data to be significantly smaller than actual value, and boiler dust discharge can not get effective control.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is, provides a kind of hot stopple coupon of companion measured for boiler near-zero release, solves in prior art and measure for boiler near-zero release, the problem that testing result error is large, improves the authenticity detecting data.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to be achieved:
For the hot stopple coupon of companion that boiler near-zero release is measured, comprise stopple coupon, described stopple coupon is divided into bend loss and straight length, and the straight length of stopple coupon is coated with one deck zone of heating, and on the straight length of stopple coupon, also cover has the sleeve pipe for encapsulating zone of heating.
The utility model also has distinguishes technical characteristic as follows:
Described zone of heating is also provided with temperature sensor.
Described zone of heating is coated with one layer of heat preservation layer, and heat-insulation layer is in also sleeve is encapsulated in.
Gap is had between described heat-insulation layer and internal surface of sleeve pipe.
Described sleeve pipe is detachable to be arranged on the straight length of stopple coupon, and the two ends of sleeve pipe are provided with end cap.
The utility model compared with prior art, has following technique effect:
The device that device of the present utility model is measured as boiler near-zero release, all applicable to industrial coal powder boiler, gas fired-boiler and coal-fired power station boiler.Apparatus structure is simple, easy to implement, effectively can ensure the advantages such as the authenticity that boiler near-zero release is measured.
Accompanying drawing explanation
Fig. 1 is one-piece construction cut-away view of the present utility model.
In figure, the implication of each label is: 1-stopple coupon, (1-1)-bend loss, (1-2)-straight length, 2-zone of heating, 3-sleeve pipe, (3-1)-end cap, (3-2)-end cap, 4-heat-insulation layer.
Below in conjunction with accompanying drawing, explanation is further explained in detail to particular content of the present utility model.
Embodiment
Below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents done on technical scheme basis all fall into protection domain of the present utility model.
Embodiment:
Defer to technique scheme, as shown in Figure 1, the present embodiment provides a kind of hot stopple coupon of companion measured for boiler near-zero release, comprises employing
12 × 2 materials are the stopple coupon 1 that the stainless-steel tube of 316L makes, described stopple coupon is divided into bend loss 1-1 and straight length 1-2, the straight length 1-2 of stopple coupon 1 is coated with the zone of heating 2 that a layer thickness is 2mm, and on the straight length 1-2 of stopple coupon 1, also cover has the sleeve pipe 3 for encapsulating zone of heating 2.
Further, the external 220V AC power of zone of heating 2, zone of heating 2 is also provided with temperature sensor.Zone of heating 2 is furnished with temperature-measuring element, i.e. temperature sensor, external control system is by the switch of temperature signal control 220V AC power, thus the temperature ensureing stopple coupon 1 is 120 ± 5 DEG C.
Further, zone of heating 2 is coated with one layer of heat preservation layer 4, and heat-insulation layer 2 thickness is 10mm, and material is hermetic type bubble structure PEVA rubber and plastic.Heat-insulation layer 4 is in also sleeve 3 is encapsulated in.For the ease of mounting bush 3, between heat-insulation layer 4 and sleeve pipe 3 inwall, there is 3mm gap.
Sleeve pipe 3 is detachable to be arranged on the straight length 1-2 of stopple coupon 1, and the two ends of sleeve pipe 3 are provided with end cap 3-1,3-2, is convenient to install.The material of sleeve pipe 3, end cap 3-1,3-2 is 316L stainless steel
The course of work of the present utility model is as described below:
During measurement, first open the 220V AC power of zone of heating 2, until the temperature of stopple coupon 1 maintains 120 ± 5 DEG C.Then stopple coupon 1 is put into chimney entrance sampling gaging hole, connect sample collection device, start boiler emission and detect.
Supersaturation wet flue gas enters stopple coupon 1 from the bend loss 1-1 end of stopple coupon 1, flow to and straight length 1-2.Temperature now in stopple coupon 1 is heated to 120 DEG C by zone of heating 2, and the liquid aerosol in supersaturation wet flue gas and fine water droplet are all heated to form gaseous state, can not meet condensation knot in stopple coupon 1.In flue gas, all dust are with air-flow by stopple coupon 1, all enter sample collection device below.
