Description

Energy saving surge tank

Technical field

The utility model belongs to boiler auxiliary equipment technical field, and in particular to a kind of energy saving surge tank.

Background technology

Steam generator be a kind of water supply by the pressure of feed pump the once-through in heating surface, generate the heat supply of steam Equipment.This design structure is succinctly smooth, and it is reasonable that heating surface arranges, and assembling manufacturing process is simple, is all obtained gradually in every field To being widely applied.But there is also a little shortcomings for current steam generator：

First, water capacity is minimum, and operating mode is unstable, without fixed carbonated drink line of demarcation, is wanted to the control technology of boiler Ask relatively high, especially the control of water pump confluent required more accurate, it is desirable that water pump feedwater flow will with vapor (steam) temperature and User's steam usage amount is at certain linear relationship.And routinely configuration is that water is sent directly into it by feed pump to steam generator In.So, since the signal for receiving vapor (steam) temperature and user's steam consumption is fed back, pump capacity wants the moment to adjust, this So that the variation frequency of water pump is very fast, pump capacity fluctuation is larger, eventually leads to steam generator to water unstable, so that The requirement of user is not achieved in vapor (steam) temperature, steam quality and steam flow；

Secondly as water capacity is minimum, to prevent steam generator water shortage, dry combustion method, according to previous commissioning test experience, It will so that confluent is slightly more than needed, can generally have more 20%~30%.The circulating ratio of steam generator is K=1, confluent Increasing so that hydrophobic amount increases i.e. additional 20%~30% water supply significantly, and hydrophobic temperature basically reaches saturation temperature, It is equivalent to this additional 20%~30% water supply to be heated to the corresponding saturation temperature of operating pressure in this way to discharge again, Virtually waste a large amount of heat so that boiler efficiency significantly reduces, and increases a large number of operating cost.

Utility model content

The purpose of this utility model is to provide a kind of energy saving surge tank, solve that existing boiler feedwater is unstable and efficiency Low problem.

Technical solution used by the utility model is：Energy saving surge tank, including horizontally disposed cylinder, the both ends of cylinder Be connected separately with water supply inlet pipe and water supply outlet pipe, cylinder is internally provided with coil pipe, the both ends of coil pipe be connected separately with it is hydrophobic into Pipe and hydrophobic outlet pipe, hydrophobic inlet pipe and hydrophobic outlet pipe stretch out in outside cylinder.

The utility model is also characterized by

Coil pipe includes the inner ring coil pipe and outer ring coil pipe of mutual fitting, and one end of inner ring coil pipe and one end of outer ring coil pipe are solid Fixed connection, the other end of inner ring coil pipe are connected to the fixation of hydrophobic inlet pipe, and the other end of outer ring coil pipe is connected to the fixation of hydrophobic outlet pipe.

The both ends of cylinder are respectively and fixedly provided with end socket, and two end sockets are located at water supply inlet pipe and cylinder, water supply outlet pipe and cylinder Between.

The bottom of cylinder is connected with blow-off pipe.

The bottom of cylinder is both provided with supporting leg close to cylinder both ends.

The utility model has the beneficial effects that：The energy saving surge tank of the utility model by setting feed pump and boiler it Between, pump capacity can not only be fluctuated and play cushioning effect, but also high temperature can be allowed hydrophobic and carry out heat exchange with low temperature feedwater, it will This hydrophobic partial heat of high temperature is recycled, and energy-efficient effect is reached.

Specific implementation mode

Below in conjunction with the accompanying drawings and the utility model is described in detail in specific implementation mode.

The utility model provides a kind of energy saving surge tank, as shown in Figure 1, include horizontally disposed cylinder 1, cylinder 1 Both ends are respectively and fixedly provided with end socket 7, and water supply inlet pipe 2 and water supply outlet pipe 3 are connected separately on the end socket 7 at 1 both ends of cylinder；Cylinder 1 it is interior Portion is provided with coil pipe 4, and coil pipe 4 includes the inner ring coil pipe 41 and outer ring coil pipe 42 of mutual fitting, one end of inner ring coil pipe 41 and outer Connection is fixed in the one end for enclosing coil pipe 42, and the other end of inner ring coil pipe 41 and hydrophobic inlet pipe 5 are fixed and be connected to, outer ring coil pipe 42 it is another End is connected to the fixation of hydrophobic outlet pipe 6, and hydrophobic inlet pipe 5 and hydrophobic outlet pipe 6 stretch out in outside cylinder 1；The bottom of cylinder 1 is connected with row Dirty pipe 8；The bottom of cylinder 1 is both provided with supporting leg 9 close to 1 both ends of cylinder.

When work, as shown in Fig. 2, boiler feedwater enters the water supply inlet pipe 2 of the utility model through feed pump 10, in cylinder 1 Interior generation heat exchange enters through water supply outlet pipe 3 in boiler 12 after absorbing heat；At the same time, the steam generator 11 of boiler 12 The high temperature of generation is hydrophobic to be entered through hydrophobic inlet pipe 5 in cylinder 1, and hot friendship occurs followed by inner ring coil pipe 41 and outer ring coil pipe 42 It changes, is discharged through hydrophobic outlet pipe 6 after releasing heat.

By the above-mentioned means, the energy saving surge tank of the utility model by be arranged between feed pump 10 and boiler 12, both Pump capacity can be fluctuated and play cushioning effect, and high temperature can be allowed hydrophobic and carry out heat exchange with low temperature feedwater, by high temperature This hydrophobic partial heat is recycled, and energy-efficient effect is reached.
