Abstract
The utility model relates to boiler sewage draining equipment, in particular to a boiler sewage draining expansion tank for the automatic expansion and temperature reduction of sewage water in a boiler; the boiler sewage draining expansion tank is characterized by at least comprising a sewage draining expansion tank (1), a temperature sensor (3), a temperature measurement and control unit (10) and an electromagnetic valve (4); a sewage draining inlet (2) of the sewage draining expansion tank (1) is communicated with the boiler sewage draining equipment; a normal temperature water inlet (5) is communicated with an input port the electromagnetic valve (4); an output port of the electromagnetic valve (4) is communicated with the sewage draining expansion tank (1) which is provided with the temperature sensor (3); the temperature sensor (3) and an input terminal of the temperature measurement and control unit (10) are in electric connection; an output port of the temperature measurement and control unit (10) and a control terminal of the electromagnetic valve (4) are in electric connection; the lower end of the sewage draining expansion tank (1) is provided with a sewage outfall (8); and the sewage outfall (8) is communicated with a drainage system (9). The boiler sewage draining expansion tank can automatically reduce the temperature of the sewage water in the boiler, reduce the occupied area and save investment.
Description
Technical field
The utility model relates to a kind of boiler blow-off wetting system, is a kind of boiler blow-off flash vessel with the automatic dilatation cooling of boiler blowdown water exactly.
Background technology
The temperature of boiler blowdown water is higher, can not directly discharge, and through behind the common blowdown system, its temperature at discharging condensate also need continue cooling through the blowdown cooling tank usually also greater than 40 ℃, so not only increase investment, and floor space is big.
Summary of the invention
The purpose of this utility model provides a kind of boiler blow-off flash vessel, so that boiler blowdown water is lowered the temperature automatically, has reduced floor space simultaneously, and has reduced investment outlay.
For achieving the above object, the technical solution of the utility model is: design a kind of boiler blow-off flash vessel, it is characterized in that: which comprises at least blowdown system 1, sewer import 2, temperature sensor 3; Thermometric control module 10, magnetic valve 4, normal-temperature water import 5; Sewer import 2 on the blowdown system 1 is communicated with boiler blow-off, normal-temperature water import 5 is communicated with magnetic valve 4 input ports, magnetic valve 4 delivery outlets are communicated with blowdown system 1, blowdown system 1 is provided with temperature sensor 3, temperature sensor 3 is electrically connected with thermometric control module 10 inputs, and thermometric control module 10 delivery outlets are electrically connected with magnetic valve 4 control ends; There is sewage draining exit 8 blowdown system 1 lower end, and sewage draining exit 8 is communicated with drainage system 9.
Be connected with hand-operated valve 6 between described normal-temperature water import 5 and magnetic valve 4 input ports.
The course of work of the present utility model and advantage: because the utility model is on the basis of common blowdown system, increased the normal-temperature water import, temperature sensor and thermometric control module are arranged in the flash vessel, when the temperature that measures boiler blowdown water when temperature sensor is higher than 40 ℃ (time temperature spot can set), open normal-temperature water by the thermometric control module and make normal-temperature water enter blowdown system with magnetic valve between the flash vessel to mix, discharge when making mixed water temperature in the blowdown system drop to below 40 ℃ with the boiler blow-off water.Integral device is structure as a whole, and has avoided being provided with separately the blowdown cooling tank again, has reduced floor space, has saved investment, and practical effect is good.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the utility model example structure schematic diagram.
Among the figure: 1, blowdown system; 2, sewer import; 3, temperature sensor; 4, magnetic valve; 5, normal-temperature water import; 6, hand-operated valve; 7, steam drain; 8, sewage draining exit; 9, drainage system; 10, thermometric control module.
The specific embodiment
As shown in Figure 1, which comprises at least blowdown system 1, sewer import 2, temperature sensor 3; Thermometric control module 10, magnetic valve 4, normal-temperature water import 5; Blowdown system 1 sewer import 2 is communicated with boiler blow-off, normal-temperature water import 5 is communicated with the input port of magnetic valve 4, the delivery outlet of magnetic valve 4 is communicated with blowdown system 1, blowdown system 1 is fixed with temperature sensor 3, temperature sensor 3 is electrically connected with thermometric control module 10 inputs, and thermometric control module 10 delivery outlets are electrically connected with magnetic valve 4 control ends.When the temperature that provides boiler blowdown water when temperature sensor 3 is higher than 40 ℃ signal, signal by thermometric control module 10 is handled, open at normal-temperature water import 5 and magnetic valve 4 between normal-temperature water is communicated with by control mouth, making normal-temperature water enter blowdown system 1 mixes with the boiler blow-off water, mixed water temperature through blowdown system 1 is dropped to below 40 ℃, and the water of sewage draining exit 8 discharges at this moment will reach discharge standard.
In addition, between being communicated with, normal-temperature water import 5 and normal-temperature water except being connected magnetic valve 4, also can increase hand-operated valve 6, with the assurance Maintenance of electromagnetic valve.When using magnetic valve 4, hand-operated valve 6 is shown in an open position.
Temperature sensor 3 in the utility model and thermometric control module 10 are owing to the product of the standard of employing is used, so its technology is not described in addition.Relevant technology contents can be understood by the relevant documents and materials of temperature survey and control.
