Abstract
The utility model discloses a kind of steam boiler backwater circulation and utilizes system, including return water accumulator tank and automatic control system, return water holding vessel upper end is connected with water return pipeline end minimum point, return water holding vessel lower end is connect by vapor transfer pipeline with boiler, vapor transfer pipeline is pumped equipped with vapor transfer, return water holding vessel is externally provided with high-temp magnetic flap level gauge and liquid level sensor, and liquid level sensor is connected by signal wire with automatic control system.The utility model water return pipeline end minimum point behind boiler room builds return water holding vessel, and holding vessel is connected in boiler by vapor transfer pump and vapor transfer pipeline.When return water liquid level reaches setting high level in holding vessel, automatic control system starts delivery pump, and return water is made to enter boiler；When liquid level reaches low value, automatic control system control delivery pump stops working, and realizes that backwater circulation work, timely high efficiente callback utilize boiler blow-down water by automatic control system.It realizes and automatically controls, operated without personnel.
Description
Technical field
The utility model belongs to boiler blow-down water technical field, and in particular to and a kind of steam boiler backwater circulation utilizes system,
It is applied especially to the steam boiler return water of explosive production process.
Background technique
During explosive production, steam heating is needed to dissolve water oil phase material, conveyance conduit heat preservation, in this process
The middle return water or steam mixture for generating a large amount of high temperature recycles delivery pump that will return currently, return water is uniformly recovered in back pool
Water is extracted into boiler, but return water temperature can reduce loss, and residual steam cannot efficiently use, and be discharged into atmosphere.
Summary of the invention
In order to solve the above-mentioned technical problem, return water and residual steam, energy saving, the utility model are preferably recycled
A kind of steam boiler backwater circulation is provided and utilizes system.
The technical solution of the utility model is as follows:
A kind of steam boiler backwater circulation utilizes system, including return water accumulator tank and automatic control system, the return water storage
It stores tank wall and is equipped with insulating layer, return water holding vessel upper end is connected with water return pipeline end minimum point, return water holding vessel lower end
It is connect by vapor transfer pipeline with boiler, vapor transfer pipeline is pumped equipped with vapor transfer, and return water holding vessel is externally provided with liquid level
Meter and liquid level sensor, liquid level sensor are connected by signal wire with automatic control system.
The insulating layer is heat-preservation cotton layer.Guarantee that return water temperature does not decline, and is directly entered boiler, is more advantageous to recycling in this way
It is energy saving using return water and residual steam.
In order to avoid return water temperature height makes vapor transfer pump generate failure, lead to system stalls, the vapor transfer
Pipeline has two, and one vapor transfer of setting pumps on every conveyance conduit, wherein a vapor transfer pump is spare.
The liquidometer includes high-temp magnetic flap level gauge and floating ball.
The automatic control system includes frequency converter, intelligence instrument, relay, contactor；The frequency converter and steam are defeated
Pump is sent to connect, intelligence instrument is connect with sensor.
The model (XMT-3) of the intelligence instrument.
The automatic control system is located in the numerical control tank of boiler room.
Liquidometer and liquid level sensor are set to return water and save tank wall.
The utility model has the beneficial effects that the utility model water return pipeline end minimum point behind boiler room builds return water storage
Tank is deposited, holding vessel is connected in boiler by vapor transfer pump and vapor transfer pipeline.When return water liquid level reaches and sets in holding vessel
When determining high level, automatic control system starts delivery pump, and return water is made to enter boiler；When liquid level reaches low value, automatic control system
Control delivery pump stops working, and realizes that backwater circulation utilizes work by automatic control system, timely high efficiente callback utilizes boiler
Return water.It realizes and automatically controls, operated without personnel.Further, return water accumulator tank is sealed thermal insulating return water holding vessel, can
Return water and residual steam are preferably recycled, it is energy saving.
Detailed description of the invention
Fig. 1 is that a kind of steam boiler backwater circulation of the utility model utilizes system schematic；
Wherein 1 is return water accumulator tank, and 2 pump for vapor transfer, and 3 be vapor transfer pipeline, and 4 be boiler, and 5 be high-temp magnetic turnover panel
Liquidometer, 6 be liquid level sensor, and 7 be water return pipeline, and 8 be floating ball, and 9 be insulating layer.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of steam boiler backwater circulation utilizes system, including return water accumulator tank 1 and automatic control system,
1 outer wall of return water holding vessel is equipped with insulating layer, and 1 upper end of return water holding vessel is connected with 7 end minimum point of water return pipeline, returns
1 lower end of water store tank is connect by vapor transfer pipeline 3 with boiler 4, and vapor transfer pipeline 3 is equipped with vapor transfer pump 2, liquid level
Sensor 6 is connected by signal wire with automatic control system.The vapor transfer pipeline 3 has two, sets on every conveyance conduit 3
A vapor transfer pump 2 is set, wherein a vapor transfer pump is spare.
The automatic control system includes frequency converter, intelligence instrument, relay, contactor；The frequency converter and steam are defeated
Send pump 3 connection, intelligence instrument is connect with sensor 6.
The automatic control system is located in the numerical control tank of boiler room.
High-temp magnetic flap level gauge 5, liquid level sensor 6 and floating ball 8 are set to 1 outer wall of return water accumulator tank.
When return water liquid level reaches setting high level in return water holding vessel, automatic control system starts vapor transfer pump, makes back
Water enters boiler；When liquid level reaches low value, automatic control system control delivery pump stops working, and passes through automatic control system reality
Existing backwater circulation utilizes work.
