Technique effect of the present utility model is:
After using the utility model; coal gas has been removed steam wherein before entering transport pipe; thereby no longer need to be provided with water-freeing arrangement in the transport pipe; avoid the leakage of toxic gas; protection life safety and environmental safety; protect pipeline not corroded simultaneously; the calorific value of coal gas is also effectively improved; in addition; the utility model is used for the coal gas heat in the pre-cooler to heat the coal gas of rewarming well heater; or the coal gas cold in the rewarming well heater is used for precooling the flow through coal gas of pre-cooler, save energy effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises housing 3, and the two ends of housing 3 are provided with gas inlet 1 and gas exit 8, and gas inlet 1 and gas exit 8 are connected with the transport pipe of coal gas respectively.Between gas inlet 1 and the gas exit 8, pre-cooler 2, at least one group of water cooler 4, water-stored section 5, mist eliminator 6 and rewarming well heater 7 sequence units are in housing 3, water cooler 4 is connected with handpiece Water Chilling Units 13 and water pump 12 by pipeline, the heat that water cooler 4 absorbs in the coal gas raises water temperature, water pump 12 reenters water cooler 4 and is the coal gas cooling after hot water is pumped into handpiece Water Chilling Units 13 coolings.Pre-cooler 2 is connected with rewarming well heater 7 by pipeline and water circulating pump 11, the heat that pre-cooler 2 absorbs in the coal gas raises water temperature, water circulating pump 11 pumps into rewarming well heater 7 with the hot water in the pre-cooler 2 and is the heating of coal gas rewarming again, water temperature reduces, water after water circulating pump 11 will be lowered the temperature pumps in the pre-cooler 2 once more does precooling for coal gas, like this, constantly the transfer of heat of ingress's coal gas is added heating gas to the exit, it is that coal gas is done precooling that the cold of exit coal gas is transferred to ingress, no longer need utilize external source to come precooling or add heating gas, save the energy effectively at pre-cooler 2 and rewarming well heater 7 places.Water-stored section 5 is a cavity, its housing bottom has a groove 501, groove 501 connects water shoot and automatic drainer 9, automatic drainer 9 enters water receiving tank 10 automatically with water, automatic drainer 9 is only discharged water, and coal gas still is enclosed in the housing, and in the present embodiment, what automatic drainer 9 used is the SDLP-30000-150 type multicell high pressure anti-leakage gas drainage device of being produced by Nantong Shendong Metallurgical Machinery Co., Ltd..
In the present embodiment, above-mentioned pre-cooler 2, water cooler 4 and rewarming well heater 7 adopt continuous fin-tube heat exchanger structure; Above-mentioned water cooler 4 only is equipped with one group, because when pressure leak source 〉=5 of coal gas °, one group of water cooler 4 is enough to reduce temperature of gas, when pressure leak source≤5 of coal gas °, need to be equipped with the water cooler 4 of two groups even more groups, just to be enough to gas temperature is dropped to below the pressure leak source; By Fig. 1,2 can see, above-mentioned mist eliminator 6 comprises with the web plate 601 of screw device on housing 3, support 603 usefulness screw devices are on web plate 601, at least two-layer baffle plate 602 usefulness screw inclination devices are on support 603, baffle plate 602 also can be welded on the support 603, the angle of inclination B (Fig. 2) of baffle plate 602 is arranged between 10 °~75 ° usually according to the size of flow, in the gas flue that between two baffle plates 602, constitutes, demister element 604 levels are inserted support 603, demister element 604 is made up of superimposed multilayer Stainless Steel Cloth in screen work, device has 602,5 layers of demister element 604 of 6 layers of baffle plate altogether in the present embodiment.
Working process of the present utility model: the coal gas that contains a large amount of water vapors that iron-smelting furnace, converter or coke oven etc. produce when ironmaking, steel-making or coking by pipe-line transportation to gas inlet 1 of the present utility model, the gas temperature of this moment is between 30 ℃~50 ℃, cooling through pre-cooler 2 and water cooler 4, most of water vapor in the coal gas is condensed into the globule, accumulate current again and flow into water-stored section 5, automatic drainer 9 enters water receiving tank 10 with the water of discharging.A large amount of water vapors in the coal gas are removed at this moment, but still contain a large amount of fog in the coal gas, coal gas is by the baffle plate 602 guiding process demister element 604 that tilt to install, on demister element 604, filter and be agglomerated into the globule, under the effect of gravity, the globule flow in the water-stored section along the baffle plate 602 that tilts, and compiles with the effusive water of condensation of pre-cooler 2 and water cooler 4 places, again by outside the automatic drainer 9 automatic device for transferring.Coal gas is at process pre-cooler 2, water cooler 4 and mist eliminator 6, its water capacity reduces widely, but its rh value still reaches 100%, in heating through rewarming well heater 7, its rh value reduces to 20%~50%, the calorific value of coal gas is effectively improved, and coal gas is sent into transport pipe from gas exit 8.
Pre-cooler 2 in the utility model, water cooler 4, rewarming well heater 7, handpiece Water Chilling Units 13, water pump 12, water circulating pump 11 and automatic drainer 9 manufacture and design or the commercial goods according to prior art.
