Description
Technical field
The utility model belongs to industrial enterprise coal gas technology field, particularly relates to a kind of mixed gas ST, is applicable to the sampling of industrial enterprise's mixed gas.
Background technology
Industrial enterprise's kinds of gas is various, mainly comprises blast furnace gas, coke-oven gas, coal gas of converter, producer gas, rock gas and liquefied petroleum gas (LPG).Wherein blast furnace gas, coke-oven gas and coal gas of converter are the by-product gas of iron and steel enterprise, and producer gas is an artificial coal gas, and the composition and the calorific value of these six kinds of coal gas have nothing in common with each other.In industrial enterprise; Industrial furnace is the main users of consumption coal gas, and the difference of industrial furnace is also different to the calorific value requirement of coal gas; For energy-saving and cost-reducing; Industrial enterprise at first all utilizes by-product gas, and insufficient section replenishes producer gas, rock gas or liquefied petroleum gas (LPG), therefore will different types of coal gas be mixed the back and supply stove to use.In order to improve the thermal efficiency of industrial furnace, often require mixed gas calorific value stable.Coal gas mixes employing flowrate proportioning regulative mode mostly at present, the on-line monitoring calorific value, and this just need measure the calorific value of mixed gas.The accuracy that calorific value of gas is measured will directly influence the calorific value that mixes back coal gas, and present coal gas mixing station is directly incorporated small pipeline into large pipeline mostly, be difficult to reach evenly after coal gas mixes like this, and different parts in the pipeline, the composition of coal gas is different.The calorific value of gas of measuring for caloric value instrument can react actual calorific value of gas, needs a kind of mixed gas ST especially.
Summary of the invention
The purpose of the utility model is to provide a kind of mixed gas ST.When carrying out the calorific value of gas detection, the gas composition that sampling is come out is identical with the actual gas composition of pipeline, to reach the calorific value monitoring accuracy, for the coal gas hybrid technology creates conditions.
The utility model comprises stopple coupon 1, sample valve 2, sweeping head 3, outgoing gas connection tube 4, stopple coupon termination 5, stub (tube) 6, support 7, stiffening plate 8.Stopple coupon 1 one ends insert in the gas piping, and the other end is connected with stopple coupon termination 5; Stub (tube) 6 is welded in the gas piping outer wall, and the end connects flange and blind flange; Stopple coupon 1 is connected with sample valve 2 after passing blind flange, connects sweeping head 3 again; Support 7 and stopple coupon 1 are through being welded to connect, and support 7 two ends are welded on the gas piping through stiffening plate 8; Connect outgoing gas connection tube 4 at stopple coupon 1 back segment, the position is between the contact and stopple coupon termination 5 of support 7 and stopple coupon 1.
The gas side of meeting that stopple coupon 1 inserts on gas piping one end has the circular hole that is evenly distributed, and makes the coal gas of the interior different parts of gas piping flow in the stopple coupon 1.
Stopple coupon 1 welds with the blind flange of stub (tube) 6 ends, and 6 pairs of stopple coupons 1 of stub (tube) play a supportive role, and when stopple coupon 1 maintenance, can extract gas piping out with blind flange.
Sample valve 2 is a ball valve, and effect is to cut off coal gas.
Sweeping head 3 is provided with ball valve, and sweeping head 3 joins with nitrogen tube during use, opens ball valve, and nitrogen is fed pipeline, and air or coal gas in the displacement stopple coupon 1 rear portion pipeline are avoided forming damp or leaked and poisons.
Outgoing gas connection tube 4 is connected with external pipe, is connected to caloric value instrument.
The advantage of the utility model is: the gas of different parts in the gas piping is flowed in the stopple coupon; Make the gas componant of going out composition near actual gas in the gas piping through stopple coupon; Thereby the online calorific value of measuring coal gas is near actual calorific value, for the accuracy of coal gas hybrid technology or the sampling of other mixed gas creates conditions.The utility model maintenance simultaneously, easy to maintenance, safe and reliable.
Description of drawings
Fig. 1 is the ST synoptic diagram of the utility model.Wherein, stopple coupon 1, sample valve 2, sweeping head 3, outgoing gas connection tube 4, stopple coupon termination 5, stub (tube) 6, support 7, stiffening plate 8.
Embodiment
Fig. 1 is a kind of embodiment of the utility model.
The utility model comprises stopple coupon 1, sample valve 2, sweeping head 3, outgoing gas connection tube 4, stopple coupon termination 5, stub (tube) 6, support 7, stiffening plate 8.Stopple coupon 1 one ends insert in the gas piping, and the other end is connected with stopple coupon termination 5; Stub (tube) 6 is welded in the gas piping outer wall, and the end connects flange and blind flange; Stopple coupon 1 is connected with sample valve 2 after passing blind flange, connects sweeping head 3 again; Support 7 and stopple coupon 1 are through being welded to connect, and support 7 two ends are welded on the gas piping through stiffening plate 8; Connect outgoing gas connection tube 4 at stopple coupon 1 back segment, the position is between the contact and stopple coupon termination 5 of support 7 and stopple coupon 1.
The gas side of meeting that stopple coupon 1 inserts on gas piping one end has the circular hole that is evenly distributed, and makes the coal gas of the interior different parts of gas piping flow in the stopple coupon 1.
