Abstract
The invention relates to a surface-type indirect air cooling system plate-type condenser of a thermal power plant, which comprises headers that are symmetrically arranged; a steam inlet is arranged above the headers, and a condensate water well is positioned under the headers; the condenser is characterized in that a heat exchanger connected between the headers has plate-type structure which is provided with a plurality of vertical metal plates; a transverse clapboard is arranged between the plate 1 and the plate 2, so that a cooling water channel is formed, and the two ends of the cooling water channel are communicated with the headers; a vertical clapboard is arranged between the plate 2 and the plate 3, so that a steam channel is formed; a transverse clapboard is arranged between the plate 3 and the plate 4, so that a cooling water channel is formed, and so on, a plate-type heat exchanger can be formed. On the premise of maintaining the original design, the plate-type condenser improves the heat transfer coefficient by 20-45%, and reduces the weight, the volume, tubes and other material consumption by 30%, thus greatly reducing the manufacturing cost.
Description
Technical field
The present invention relates to the condensation heat transfer equipment of thermal power plant surface-type indirect air cooling system.
Background technology
Thermal power plant's air cooling technique is just to grow up nearly half a century.Since the last century the eighties, the large electric power plant unit of air cooling technique in the landlocked water-deficient area of China obtains to use widely, built and building air cooling power station total installation of generating capacity above 7,000 ten thousand kilowatts.In air cooling technique, adopt the indirect air cooling system (claiming the Harmon system again) of surface condenser to be used widely, this system is made of surface condenser and the air cooling tower that radiator is housed, similar substantially with the humid-cool system of routine, difference is the clammy tower that replaces hybrid evaporative cooling heat exchange with the air cooling tower of surface-type heat convection, replace the copper pipe condenser with stainless steel pipe condenser, replace recirculated water with alkaline demineralized water, replace the open type recirculating cooling water system with Enclosed Type Circulating Cooling Water System.
The condenser of surface condenser indirect air cooling system has adopted the heat pipe-type structure, the heat exchanger of condenser is made up of the water-cooled tube bank, between header, connect the water-cooled beam tube, cooling water and condensate water are divided into two autonomous systems, constitute independent loop separately, so two kinds of water quality can require to carry out Water Treatment according to difference, thereby make that water treatment system is simple, water quality is also easy to control.It is owing to adopted surface condenser that table coagulates formula indirect air cooling system major defect, need carry out twice heat exchange in the system, so the end difference is higher, the thermal efficiency decreases, and the film-cooled heat of heat pipe-type condenser is strengthened relatively, and investment is increased.
Summary of the invention
The surface-type indirect air cooling system plate-type condenser of thermal power plant that the object of the present invention is to provide a kind of heat exchange efficiency height, cost to reduce, the present invention includes symmetrically arranged header, cooling water inlet and outlet are arranged on the header, connect heat exchanger between the header, the header top is the steam inlet, there is hot well the header below, it is characterized in that the heat exchanger that connects between the header is a plank frame, plank frame has the metallic plate of several settings, between plate 1 and the plate 2 lateral partitions is set, constitute cooling-water duct, the cooling-water duct two ends are communicated with header; Between plate 2 and the plate 3 vertical dividing plate is set, constitutes steam channel; Between plate 3 and the plate 4 lateral partitions is set, constitutes cooling-water duct; Between plate 4 and the plate 5 longitudinal baffle is set, constitutes the water vapour passage; By that analogy, constitute plate type heat exchanger.
Plate-type heat exchange structure can make that the active thermal resistance of condensing, thermal-convection resistance and dirtiness resistance decline to a great extent in the condenser diabatic process, is fit to very much this application scenario of indirect air cooling system surface condenser.Use plate-type heat exchange structure, can keep under the constant situation of former design, make the heat transfer coefficient of condenser improve 20%～45%, in other words, just can make the heat exchange area of condenser increase 20%～45%.Guaranteeing under the constant situation of cooling capacity,, can make condenser weight, volume, tubing and other material consumption reduce 30%, thereby can reduce the condenser cost greatly for newly-designed condenser.And this compact conformation degree is big, and floor space is little, saves the main building space, simultaneously, the technical program is energy-conservation to circulation, water saving has significant contribution, has both reduced water circulating pump power consumption in the circulatory system, have and to reduce the circulation circulating ratio, reduce quantity of circulating water, reduced operating cost.

The specific embodiment
As shown in Figure 1, the header of condenser is symmetrical set, and cooling water inlet and outlet are arranged on the header, and there is the steam inlet header top, there is hot well the below, connect plate type heat exchanger between the header, the vertical spaced set of the corrosion resistant plate of plate type heat exchanger is provided with lateral partitions between corrosion resistant plate 1 and the plate 2, lateral partitions is triangularly arranged, become 60 degree angles between dividing plate is mutual, constitute the corrugated cooling-water duct, the cooling-water duct two ends are communicated with header; Between plate 2 and the plate 3 vertical dividing plate is set, the end face seal of plate 2 and plate 3, vertical dividing plate is triangularly arranged, and becomes 60 degree angles between dividing plate is mutual, constitutes the corrugated steam channel, between plate 3 and the plate 4 lateral partitions is set, and constitutes cooling-water duct; Between plate 4 and the plate 5 longitudinal baffle is set, constitutes the water vapour passage, by that analogy, constitute plate type heat exchanger.Be provided with evacuation passageway at the plate type heat exchanger middle part.
