Description
Technical field
The utility model relates to a kind of boiler automatic sewage discharging device, belongs to the waste heat recovery apparatus technical field, is applied in the automatic control of steam boiler continuous blowdown and the recycling aspect of sewer waste heat.
Background technology
Steam boiler need constantly carry out continuous blowdown in running, get rid of the high stove water of salt content, and the water quality of stove water is reached the set quota, and could guarantee the security of operation of boiler like this.What at present, the continuous blowdown of most steam boilers adopted is artificial process.The lab technician carries out sample examination to stove water, when the water quality index (chlorine root or basicity) of stove water surpasses specified standard, drives big blowoff valve continuously with regard to the artificially; When the water quality index of stove water is lower than specified standard, turn down the continuous blowdown valve with regard to the artificially.Artificial blowdown can only be interrupted to be carried out, and the most comparison methods that adopt of water quality detection, can not guarantee the accuracy of measurement result, therefore can cause stove water overproof water quality sometimes, influences the safe operation of boiler; Sometimes stove water water quality index is very low, causes a large amount of losses of water resource and heat.
The utility model content
The technical problems to be solved in the utility model provides a kind of boiler automatic sewage discharging device, is applied in the waste heat recovery of the automatic control of steam boiler continuous blowdown and sewer.
The technical solution of the utility model is: this device comprises heat recovery heat exchanger, electric control valve, conductivity meter, sewer overflow pipe and blowoff valve.Wherein electric control valve and conductivity meter are installed on the sewer inlet of heat recovery heat exchanger; Sewer overflow pipe and blowoff valve are installed on the sewer delivery port of heat recovery heat exchanger.
Heat recovery heat exchanger adopts the vertical shell-and-tube structure, is made up of tube sheet, heat exchanger tube, shell, sewer inlet, sewer outlet, demineralized water inlet, demineralized water outlet, exhaust outlet and discharge outlet.The flow through outside of heat exchanger tube of the flow through inside of heat exchanger tube of demineralized water, sewer.The heat of sewer exchanges to demineralized water by heat exchanger tube.Between sewer inlet and the heat exchanger tube impingement baffle is installed, is used to reduce the impact of sewer exchange heat pipe.
Electric control valve is installed on the sewer water inlet pipe of heat recovery heat exchanger.
Conductivity meter is installed on the bypass capillary of electric control valve.In bypass capillary, have a spot of stove water to flow through, conductivity meter detects the water quality of stove water and transfers out 4～20mA signal, by the aperture of this signal controlling electric control valve, thereby the water amount of blowdown of control boiler, the water quality that guarantees stove water is in a reasonable range.
The sewer outlet of heat exchanger is equipped with the sewer overflow pipe.Have only when the sewer water level of accumulation in the heat exchanger is higher than overflow pipe, sewer ability outflow heat exchanger, its effect is to have prolonged the time of staying of sewer in heat exchanger, guarantees that the heat of sewer exchanges fully to demineralized water.Blowoff valve is installed in the sewer outlet of heat exchanger, and opening valve can all emit the sewer in the heat exchanger.
The utility model beneficial effect is a continuous blowdown process of controlling boiler effectively, has guaranteed the water quality index of stove water, and can reclaim the waste heat of sewer.
