Description

Negative pressure heat exchangers for district heating
Technical field
The utility model relates to belong to heating field, especially a kind of negative pressure heat exchangers for district heating.
Background technique
Most of steam power plant can mostly use greatly back pressure turbine to drag circulating pump for preferably energy-saving and emission-reduction now Technology, economizing on energy and electricity.And the exhaust steam pressure of back pressure turbine is generally lower, absolute pressure is about 0.05~0.25MPa, well below Main steam pressure.So the absorption of back pressure steam discharge generally takes the mode for increasing a steam exhaust heat exchanger to solve.But due to Exhaust steam pressure is low, and pervious steam discharge positive pressure takes normal heat exchangers for district heating heat exchange structure can use, and negative pressure cannot be used, It generally just discharges, does not meet the objective of energy-saving and emission-reduction.
Utility model content
The technical assignment of the utility model is to provide a kind of negative pressure heat exchangers for district heating in view of the deficiency of the prior art, The negative pressure heat exchangers for district heating has the steam discharge for taking full advantage of steam turbine, the characteristics of having saved the energy, reduced operating cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows: it includes shell, left head and right end socket, It is provided with left head on the left of the shell, right end socket is provided on the right side of shell, the left head top is provided with out The mouth of a river, lower part are provided with water inlet, and the top setting of the shell is there are two steam inlet, and lower part is provided with drain port, institute Continuous gland steam exhauster is provided in the shell stated, shell, and an external blower are stretched out in one end of the continuous gland steam exhauster, described Continuous gland steam exhauster includes vertical tube and transverse tube, and the transverse tube is horizontally set on the middle part of shell, one end of the vertical tube and cross Pipe is connected, and the other end stretches out shell, is provided with multiple air inlets on the circumferencial direction of the transverse tube.
Air inlet on the transverse tube is from left to right in the setting of multiple row interval, spacing distance 40mm.
Each column air inlet respectively includes 8 air inlets, and 8 air inlets are circumferentially uniformly arranged along transverse tube.
The diameter of each air inlet is respectively 6mm.
The outer diameter of the vertical tube and transverse tube is respectively 50mm.
The shell includes large cylinder and small cylinder, and small cylinder includes two, is separately positioned on the left and right two of large cylinder Side is connected with two half-wave expansion joints respectively between large cylinder and two small cylinders, and the wave height of the half-wave expansion joint is 0.5m。
Compared to the prior art the negative pressure heat exchangers for district heating of the utility model, has following prominent the utility model has the advantages that abundant The steam discharge of steam turbine is utilized, negative pressure steam is allowed to smoothly enter inside negative pressure heat exchangers for district heating, thus realize that negative pressure exchanges heat, section The about energy, the features such as reducing operating cost.

Specific embodiment
The negative pressure heat exchangers for district heating of the utility model is described in detail below referring to Figure of description 1 and attached drawing 4.
The negative pressure heat exchangers for district heating of the utility model, structure include shell 1, left head 2 and right end socket 3, the shell The left side of body 1 is provided with left head 2, and the right side of shell 1 is provided with right end socket 3, and 2 top of left head is provided with water outlet 4, lower part is provided with water inlet 5, and there are two steam inlets 6 for the top setting of the shell 1, and lower part is provided with drain port 7, institute Continuous gland steam exhauster 8 is provided in the shell 1 stated, shell 1, and an external blower 9 are stretched out in one end of the continuous gland steam exhauster 8, The continuous gland steam exhauster 8 includes vertical tube 81 and transverse tube 82, and the transverse tube 82 is horizontally set on the middle part of shell 1, described One end of vertical tube 81 is connected with transverse tube 82, and the other end stretches out shell 1, is provided on the circumferencial direction of the transverse tube 82 multiple Air inlet 821.
Air inlet 821 on the transverse tube 82 is from left to right arranged in multiple row interval, spacing distance 40mm.
Each column air inlet 821 respectively includes 8 air inlets, and 8 air inlets are circumferentially uniformly arranged along transverse tube 82.
The diameter of each air inlet 821 is respectively 6mm.
The outer diameter of the vertical tube 81 and transverse tube 82 is respectively 50mm.
The shell 1 includes large cylinder 11 and small cylinder 12, and small cylinder 12 includes two, is separately positioned on large cylinder 11 The left and right sides, be connected respectively with two half-wave expansion joints 13 between large cylinder 11 and two small cylinder 12, the half-wave is swollen The wave height of swollen section 13 is 0.5m.Which not only adds the diameter of negative pressure heat exchangers for district heating, between large cylinder 11 and small cylinder 12 Space negative pressure steam can be allowed to be easier to enter inside negative pressure heat exchangers for district heating.
