Abstract

The utility model relates to a steam boiler's excretion machine, concretely relates to boiler blow -off cooler, including the boiler, the export pipeline of boiler is connected with the blow off pipe, the last blowoff valve that is provided with of export pipeline, still be connected with the blow down cooler between boiler and the blow off pipe, the blow down cooler includes tube and conveyer pipe, the conveyer pipe is established inside the tube, conveyer pipe both ends intercommunication export pipeline and blow off pipe, be equipped with the water inlet and the delivery port of cooling water on the tube, high temperature sewage that the boiler blow -off cooler of this scheme of adoption enabled boiler exhaust reaches national emission standard and relatively to have a cost lower with traditional periodical blowdown cooler, the little heat recovery function that has concurrently simultaneously of area.

Description

Boiler blow-off cooler
Technical field
The utility model relates to the Regular Drain system of steam boiler, is specifically related to boiler blow-off cooler.
Background technology
Because (below 8T/H) little tonnage steam boiler is when designing boiler room, user seldom requires be equipped with periodical blowdown expander or do blowdown cooling tank, the high-temperature water of boiler blow-off is collected and processed, but sewer is directly put into trench and bleeds off.
Trace it to its cause:
1. little tonnage boiler blow-off amount is only 5% of boiler capacity per hour less;
2. compare directly discharge to be equipped with periodical blowdown expander or to do blowdown cooling tank, increasing investment and increase boiler room floor space, is all that user is unwilling to see.
By the steam boiler of boiler nominal steam pressure 1.0MPa, the stove coolant-temperature gage 184 DEG C that blowdown is discharged, absolutely large number user (especially in private unit) adopts directly discharged to the mode of trench, allows sewer cooling naturally inside trench (can not more than 40 DEG C to tube net outside temperature at discharging condensate by relevant national standard regulation).The impact of following several respects can be caused like this:
1. stove coolant-temperature gage height is not through supercooling, flash distillation can produce steam, affect boiler room environment (especially winter is more obvious) during external blowdown;
2. stove water exhaust temperature is high, also has 100 DEG C, easily scald personnel after flash distillation;
3. high temperature furnace water is directly drained, and wastes energy, and boiler heat loss is large.
Utility model content
The utility model be intended to provide a kind of cost lower, sewage temperature can be made to reach the boiler blow-off cooler of discharging standards.
Boiler blow-off cooler in this programme, comprise boiler, the outlet conduit of boiler is connected with blow-off pipe, outlet conduit is provided with blowoff valve, also be connected with blow down cooler between described boiler and blow-off pipe, described blow down cooler system comprises shell and carrier pipe, and described carrier pipe is located at shell inside, carrier pipe two ends are communicated with outlet conduit and blow-off pipe, and described shell is provided with water inlet and the delivery port of cooling water.
The utility model has the advantages that: on the blow-off line of boiler, increase by a blow down cooler carry out exchange heat, blow down cooler side access cold water carries out cooling the exhaust temperature (40 DEG C) boiler blow-off high-temperature-hot-water out being dropped to rapidly national regulation, thus ensure the security of discharge, cooling water enters after in blow down cooler shell and cools carrier pipe, flows out after cooling water enters from water inlet from delivery port.
Further, also comprise recovery channel, described outlet pipe connects boiler by recovery channel.The high-temperature cooling water of discharging from delivery port directly enters boiler, by heat recovery and utilization.
Further, described carrier pipe is helix tube.Because in boiler, HTHP sewage directly discharges, produce high-velocity flow, flow through helix tube, produce comparatively large disturbances, improve heat exchange efficiency; Comprise a large amount of impurity (as dirt, iron rust etc.) due in the sewage that boiler is discharged, effluent stream, through helix tube, is forced to forcibly changing water (flow) direction, and helix tube inwall can be rinsed well by high-velocity flow and the impurity with current flowing, prevents blocking.
Further, described carrier pipe has many, and in staggered spread configuration.Use many helix tubes to carry, improve cooling effectiveness, be conducive to blowdown simultaneously, heat exchanger can not be caused to block.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model boiler blow-off cooler embodiment.
In figure, 1 is boiler, and 2 is outlet conduit, and 3 is blowoff valve, and 4 is helix tube, and 5 is shell, and 6 is water inlet, and 7 is delivery port, and 8 is recovery channel, and 9 is blow-off pipe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
According to Fig. 1, a kind of boiler blow-off cooler, comprise boiler 1, the outlet conduit 2 of boiler 1 connects blowoff valve 3, and blowoff valve 3 connects the carrier pipe of blow down cooler, carrier pipe comprises many helix tubes 4, helix tube 4 two ends are connection outlet pipeline 2 and blow-off pipe 9 respectively, uses the effect of many bolt tube to be increase sewage cooling path, increases the contact area of cooling, improve heat exchanger effectiveness, in the present embodiment, preferably use three helix tubes 4.During boiler blow-off, in boiler, the stove water of HTHP is by outlet conduit 2, flows through helix tube 4, blow-off pipe 9 discharges.Effluent stream at a high speed, when helix tube, owing to being forced to forcibly changing water (flow) direction, can producing greater impact to the inwall of helix tube 4, and then produce comparatively large disturbances, improve heat exchange efficiency; Also can prevent the impurity blocking helix tube 4 in sewage simultaneously.Be the shell 5 of blow down cooler outside helix tube 4, shell 5 be connected with water inlet 6 and the delivery port 7 of cooling water.Water inlet 6 and delivery port 7, respectively at the two ends of shell 5, are so also to fully use cooling water.And delivery port 7 is also connected with boiler 1 by recovery channel 8, after high temperature sewage boiler being discharged with helix tube 4 contact heat-exchanging in shell 5 when cooling water cools, high-temperature cooling water is directly recovered into boiler 1, by high-temperature cooling water by heat recovery and utilization.Like this, the cooling of sewage and the heat recovery of sewage can be realized.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
