Description
Technical field
The utility model relates to a kind of combustion gas sampler, belongs to the gas-fired equipment technical field.
Background technology
At present; The amount of combustion gas sample dust-laden and the various impurity got that all has the numerous gas ductwork sampler that uses in the production do not conform to the actual conditions, the amount phenomenon on the low side of measured impurity such as combustion gas dust-laden; And sampling pipe is often stopped up by impurity such as the dust in the combustion gas, tar, thereby cause the post to control personnel the cleaner parameter setting is lost accuracy.The reason that this phenomenon produces is anti-skin effect, and promptly the flow velocity of combustion gas is maximum in the middle of the gas pipeline, and is low more the closer to the tube wall flow velocity.Must make that like this amount of impurity such as the middle combustion gas dust-laden of gas pipeline is high, low near the amount of impurity such as tube wall combustion gas dust-laden.And the sampler of installing on the existing gas pipeline generally all is direct perforate welding stopple coupon from the pipeline; The combustion gas sample of getting is near the less coal gas of impurity such as slow, dust of flow velocity and the tar tube wall, and therefore measured impurity levels such as combustion gas dust-laden do not conform to the actual conditions.For the deviation of the amount of impurity such as the actual dust-laden of combustion gas in the amount of effectively eliminating impurity such as combustion gas sample dust-laden and the pipe network, accurately set the parameter of combustion gas dust removal installation, be necessary very much existing equipment is improved.
The utility model content
The utility model purpose provides a kind of combustion gas sampler, eliminating the deviation of impurity contents such as actual dust-laden in combustion gas sample and the pipe network, thereby can accurately confirm the parameter of combustion gas impurity level, makes the interior actual index of combustion gas of combustion gas sample accurate response pipe network.
The utility model solves the technical scheme that its technical matters adopted:
A kind of combustion gas sampler; Comprise sleeve pipe, flange, stopple coupon, sample valve, ball valve or gate valve, rotatable axle sleeve seal in the composition; The both ends of the surface of ball valve or gate valve are fastened with flange respectively, and the inner flange of ball valve or gate valve is fixedly connected with an end of sleeve pipe, and the other end of sleeve pipe is connected with the tube wall vertical fixing of gas pipeline; Rotatable axle sleeve seal is arranged in the middle of the flange of ball valve or gate valve outer end; And be sleeved on the stopple coupon, an end of stopple coupon passes rotatable axle sleeve seal, is stretched in the gas pipeline by ball valve or gate valve, sleeve pipe, and the other end of stopple coupon is provided with sample valve.
The termination portion that above-mentioned combustion gas sampler, said stopple coupon stretch in the gas pipeline is provided with 90 ° of elbows.
Above-mentioned combustion gas sampler, the inlet end of said stopple coupon stretch into 1/3 place of gas pipeline diameter.
The beneficial effect of the utility model is; The sample position is combustion gas mean flow rate place in gas pipeline; Can effectively eliminate the deviation of the amount of impurity such as the actual dust-laden of combustion gas in amount and the pipe network of impurity such as combustion gas sample dust-laden, each item index that can the interior combustion gas of accurate response gas ductwork, and can produce in batch; Can be applicable to different types of gas ductwork well, have simple structure, life cycle length, change advantage convenient, economy and durability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model user mode 1 synoptic diagram.
Fig. 2 is the utility model user mode 2 synoptic diagram.
1. sleeve pipes among the figure, 2. flange, 3. stopple coupon, 4. sample valve, 5. ball valve or gate valve, 6. rotatable axle sleeve seal, 7. gas pipeline.
Embodiment
In embodiment illustrated in figures 1 and 2; The flanges 2 that are arranged at ball valve or gate valve 5 the inners are connected with an end of sleeve pipe 1; The other end of sleeve pipe 1 and 6 vertical being connected of gas pipeline; Rotatable axle sleeve seal 6 is arranged in the middle of the flange 2 of ball valve or gate valve 5 outer ends, and is sleeved on the stopple coupon 3, and an end of stopple coupon 3 passes rotatable axle sleeve seal 6, stretches into 1/3 place of about pipe diameter in the gas pipeline by the entrance point of ball valve or gate valve 5, stopple coupon.90 ° of bend pipes of the entrance point head of stopple coupon 3 welding, the mouth of pipe is set lead angle, and the other end is installed a small ball or gate valve as sample valve 4, and flange 2 and sleeve pipe 1 that ball valve or gate valve 5 are inboard connect through being weldingly connected between sleeve pipe 1 and the gas pipeline.
During operate as normal, ball valve or gate valve 5 are normally open.The mouth of pipe direction of stopple coupon 3 and gas-flow are on the contrary during sampling; Open sample valve 4; The combustion gas sample is collected after flowing out through stopple coupon 3, and sampling is closed sample valve 4 after accomplishing, and rotates to the mouth of pipe of stopple coupon 3 identical with gas flow; The mouth of pipe of stopple coupon 3 has lead angle, can prevent that impurity such as combustion gas dust is long-pending to drop on the mouth of pipe and stopple coupon 3 is stopped up.If stopple coupon 3 is still blocked, can ball valve or gate valve 5 outer flange 2 bolts be laid down, stopple coupon 3 is extracted out, close ball valve 5 simultaneously rapidly, in case a large amount of gas leakage after stopple coupon 3 mediation cleanings, is opened ball valve 5 to reinstall again and can be continued to use.
In this example; Ball valve or gate valve and casing diameter are 80-100mm; The stopple coupon diameter is 8-12mm, in other instances, and can be according to how many definite ball valves of impurity levels such as combustion gas kind and dust-laden or the diameter of gate valve, sleeve pipe and stopple coupon; Can link to each other with flexible pipe behind the sample valve, flexible pipe is connected to assay apparatus or sampling bag.
