Abstract
The utility model discloses a condensate water recycling system of a small steam boiler, which comprises a condensate water collecting cylinder and a boiler drum with a soft water-supply tube, wherein the soft water-supply tube is provided with a water-supply check valve; the output tube of the condensate water collecting cylinder is provided with a reciprocating pump; the outlet tube of the reciprocating pump is provided with a check valve; and the output end of the outlet tube is connected to the soft water-supply tube between the water-supply check valve and the boiler drum. The reciprocating pump can pressurize condensate water from the condensate water collecting cylinder, which can quickly pressurize condensate water with high temperature in the condensate water collecting cylinder into the boiler drum preferentially, and can shorten temperature rise time of water in the boiler drum, so coal can be saved by more than 5%. The recycling system has obvious economic benefit for boilers with the operating method of discontinuous water filling.
Description
Technical field
The utility model relates to a kind of small steam boiler condensed water recycling system.
Background technology
Usually the condensed water that forms after the producing steam work of small steam boiler institute is to return or flow to certainly in the water supply softened water tank with heat-exchanger pump.The temperature of condensed water is than the water temperature height in the water supply softened water tank, but when more a spot of relatively condensed water is mixed in the water supply softened water tank, regulate little for the water temperature in the water supply softened water tank, can not make the higher condensed water of temperature be back in the boiler drum in the shortest time, to shorten the heating-up time of water in the boiler drum, can not utilize the heat of condensed water more fully, cause coal consumption higher simultaneously, particularly very for the boiler that is interrupted upward water running.
The utility model content
The technical problems to be solved in the utility model provides a kind of small steam boiler condensed water recycling system that can make full use of condensed water heat.
For solving the problems of the technologies described above, the small steam boiler condensed water recycling system that is provided, comprise condensed water surge drum and the boiler drum that has the soft water feed pipe, the soft water feed pipe is provided with feed-check valve, its design feature is: the efferent duct of condensed water surge drum is provided with reciprocating pump, on the outlet pipe of reciprocating pump check-valves is installed, the output end of outlet pipe is connected on the soft water feed pipe between feed-check valve and the boiler drum.
After adopting said structure, because the efferent duct of condensed water surge drum is provided with reciprocating pump, on the outlet pipe of reciprocating pump check-valves is installed, the output end of outlet pipe is connected on the soft water feed pipe between feed-check valve and the boiler drum, reciprocating pump can be given the condensed water of coming in condensed water surge drum pressurization, make the high-temperature condensation water in the condensed water surge drum preferentially be squeezed in the boiler drum rapidly, also can shorten the heating-up time of water in the boiler drum, can economize on coal more than 5%, more remarkable to the boiler economic benefit of being interrupted water running.
As improvement of the present utility model, on the described efferent duct stop valve is installed, can regulate and control the liquid level in the condensed water surge drum.
As improvement of the present utility model, on the described outlet pipe safety valve is installed, can monitor the hydraulic pressure on the outlet pipe, guarantee the reciprocating pump safe operation.
As improvement of the present utility model, on the described condensed water surge drum liquid level gauge and pressure-equalizing pipe are installed, liquid level gauge can be monitored the moisture storage capacity in the condensed water surge drum at any time, and pressure-equalizing pipe communicates with atmosphere, can guarantee that condensed water flow in the condensed water surge drum smoothly certainly from the steam place to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is the condensed water surge drum, and 2 is reciprocating pump, and 3 is check-valves, and 4 is the soft water feed pipe, and 5 is stop valve, and 6 is liquid level gauge, and 7 is boiler drum, and 8 is safety valve, and 9 is feed-check valve, and 10 is efferent duct, and 11 is outlet pipe, and 12 is pressure-equalizing pipe.
The specific embodiment
Small steam boiler condensed water recycling system as shown in Figure 1, comprise the condensed water surge drum 1 that to collect boiler steam condensate water, one side of condensed water surge drum 1 is equipped with the liquid level gauge 6 that can detect condensed water surge drum middle water level, the pressure-equalizing pipe 12 that communicates with atmosphere also is housed on the condensed water surge drum 1, to guarantee that condensed water is smoothly from flowing in the condensed water surge drum 1, efferent duct 10 ends of condensed water surge drum 1 are provided with reciprocating pump 2, and stop valve 5 is installed on the efferent duct 10.By water (flow) direction safety valve 8 and check-valves 3 are installed successively on the outlet pipe 11 of reciprocating pump 2, the terminal water delivery end with make-up pipe 4 of the output of outlet pipe 11 is connected on the boiler drum 7 jointly, soft water feed pipe 4 is provided with feed-check valve 9, can guarantee that soft water does not flow backwards, the output end of outlet pipe 11 is located on the soft water feed pipe 4 between feed-check valve 9 and the boiler drum 7, the water supply end of soft water feed pipe 4 is connected on the water supply softened water tank, and the soft water supply of soft water feed pipe 4 only is used for regulating the water level of boiler drum 7 to guarantee safe operation of the boiler.
