Content of the invention:This utility model purpose is, exists in waste heat recovery for existing low-pressure industrial steam boiler Deficiency, and a kind of steam boiler blowdown heat reclamation device is proposed, it has the advantages that waste heat recovery rate is high.
By following technical proposals, achievable the purpose of this utility model, a kind of steam boiler blowdown heat reclamation device, its It is characterised by, including waste heat recovery tank, heat exchanger, support;Waste heat recovery tank includes tank body, ring-shape open formula chuck, soda pop are divided From setting, isolation ring, hydroecium, shower nozzle;The top of tank body is provided with evacuation port, and bottom is provided with hot water outlet, and side wall is respectively equipped with pot Fire grate wastewater inlet, softening water inlet, boiler blow-off water out;Ring-shape open formula chuck is opening up be located at interior in the middle part of tank body Wall, steam-water separation equipment is set in ring-shape open formula chuck, and isolation ring is located at the overthe openings of ring-shape open formula chuck, and hydroecium sets On the top of tank inner chamber, shower nozzle is located at hydroecium bottom, and hydroecium passes through pipeline and is connected with softening water inlet, and boiler blowdown water enters Mouth and boiler blow-off water out and ring-shape open formula chuck cavity UNICOM;Waste heat recovery tank and heat exchanger are fixed by support;Change Hot device is provided with room temperature softened water inlet and outlet, and room temperature softens the softening water inlet that water out passes through pipeline and waste heat recovery tank Connect;Heat exchanger is provided with boiler blow-off water inlet, and it is connected with waste heat recovery tank boiler blow-off water out by pipeline.
Described steam-water separation setting is mainly made up of resistance vapor baffle and packing layer, and resistance vapor baffle is annular flap, and two pieces are One group of two-way middle part being located at ring-shape open formula chuck, packing layer is located at the top of ring-shape open formula chuck.
For ease of installation and maintenance, waste heat recovery tank is made up of through bolt connection upper cover, canister, low head three.
Effect of the present utility model is:1st, waste heat recovery effect is good, saves the energy, the blowdown of recyclable steam boiler institute Most heats in water, with existing apparatus ratio, can improve waste heat recovery rate 85~90, this essentially consists in, this device sets There are two waste-heat recovery devices, the softened water after atomization and the direct condensation by mixing of flash steam guarantee to dodge in waste heat recovery tank Steam recycles completely;In addition, after flash distillation dilatation in room temperature softened water and the waste heat recovery tank in indirect type heat exchanger Discharge 95 DEG C of stove water and carry out heat exchange recovery, finally, sewage temperature can be made to drop to less than 40 DEG C and discharge, not only again elimination emitted energy-conservation Vapour;2nd, simplify device, this is, this device instead of the platoon flash vessel in existing apparatus and surely arranges flash vessel, and, effect Fruit is also good than both;3rd, it is beneficial to environmental conservation, eliminate the thermal pollution to environment.
Brief description:
The process structure schematic diagram that accompanying drawing 1 is connected with auxiliary equipment for existing steam boiler.
Accompanying drawing 2 is structural representation of the present utility model.
The process structure schematic diagram that accompanying drawing 3 is connected with this utility model and part auxiliary equipment for steam boiler.
Below in conjunction with the accompanying drawings and embodiment is expanded on further to this utility model:
Specific embodiment:
Referring to accompanying drawing 2,3, a kind of steam boiler blowdown heat reclamation device, it mainly by waste heat recovery tank A, heat exchanger B, Frame C forms.Waste heat recovery tank A mainly by tank body 7, ring-shape open formula chuck 8, steam-water separation setting 9, isolation ring 10, hydroecium 11, Shower nozzle 12 forms.The top of tank body 7 is provided with evacuation port 13, and bottom is provided with hot water outlet 14, and side wall is respectively equipped with boiler blowdown water Import 15, softening water inlet 16, boiler blow-off water out 17.Ring-shape open formula chuck 8 is opening up to be located in tank body 7 middle part Wall, steam-water separation setting 9 is located in ring-shape open formula chuck 8, and its function is that 1 grate furnace water of boiler is carried out steam-water separation. Isolation ring 10 is located at the overthe openings of ring-shape open formula chuck 8, and its function is not allow the sprayed softened water of shower nozzle 12 enter into ring Cause in the open chuck of shape 8 to soften water loss.Hydroecium 11 is located at the top of tank body 7 inner chamber, and its function is to make softened water equal Even be distributed in each shower nozzle, shower nozzle 12 is located at hydroecium 11 bottom.Hydroecium 11 passes through pipeline and is connected with softening water inlet 16.Boiler is arranged Wastewater inlet 15 is connected with ring-shape open formula chuck 8 cavity with boiler blow-off water out 17.Waste heat recovery tank A and heat exchanger B leads to Cross support C to fix.Heat exchanger B is provided with room temperature and softens water inlet 18 and soften water out 19, softens water out 19 and passes through pipeline It is connected with the softening water inlet 16 of waste heat recovery tank.Heat exchanger B is provided with boiler blow-off water inlet 20, and it passes through pipeline and waste heat Recycling can boiler blow-off water out 17 connects, and heat exchanger B is provided with boiler blow-off water out 21.The setting of described steam-water separation can be by Resistance vapor baffle 91 and packing layer 92 are constituted, and resistance vapor baffle 91 is annular flap, and two pieces is that one group of two-way ring-shape open formula that is located at is pressed from both sides The middle part of set 2, packing layer 92 is located at the top of ring-shape open formula chuck 2, and filler is web material.For ease of installation and maintenance, Tank body 1 is made up of through bolt connection upper cover 71, canister 72, low head 73 three.The platoon outlet of sewer of boiler 1 and fixed row expand Outlet of sewer is connected with the boiler blow-off water inlet 15 of waste heat recovery tank A by pipeline.The hot water outlet 14 of waste heat recovery tank A leads to Piping is connected with softening water tank 6.The room temperature of heat exchanger B is softened water inlet 18 and is connected with softening water tank 6 by pipeline.Steam divides Orchestration 4 one end is connected the other end with boiler 1 and is connected with oxygen-eliminating device 5, oxygen-eliminating device 5 respectively with softening water tank 6, oxygen-eliminating device 5, boiler 1 Connect, softening water tank 6 is connected with oxygen-eliminating device 5, waste heat recovery tank A, heat exchanger B respectively.
