Abstract
The utility model relates to a self-clean air heat exchanger which comprises an air heat exchanger and a controlling circuit. The utility model is characterized in that the back end of a ventilating duct of the air heat exchanger is provided with a flushing device. The front and back sides of the ventilating duct of the air heat exchanger are provided with pressure differential controllers connected with the controlling circuit. The bottom of the air heat exchanger is provided with a condensate water disk which is provided with a drainage pipeline. The utility model with the advantages of simple structure, easy fabrication, easy use, etc. can automatically clean the air heat exchanger. The utility model not only can ensure the normal operation of air-handling units, but also can save a great amount of human power and material resources to achieve the effects of economy and energy-saving.
Description
(1), affiliated technical field
The utility model relates to a kind of air heat exchanger, particularly a kind of air heat exchanger that can wash.
(2), technical background
Air heat exchanger in the existing air-treatment unit---surface air cooler and air heater, when the full dust of knot or dust are tied to a certain degree, can make air-treatment unit resistance increasing, systematic air flow is more and more littler, until calm, whole system can have to be out of service because of the ability of not having automatic cleaning, and the building enclosure that can only remove the air-treatment unit takes out of unit with air heat exchanger and clean, and cleans and assemble unit again after finishing.This has not only influenced the operation of air-treatment unit, has also wasted great amount of manpower and material resources.
(3), summary of the invention
The purpose of this utility model just provides a kind of self-cleaning air heat exchanger simple in structure and easy to use, and it is the scavenging air heat exchanger automatically, saves great amount of manpower and material resources, guarantees the normal operation of air-treatment unit.
The purpose of this utility model is to realize by such technical scheme, it includes air heat exchanger and control circuit, it is characterized in that: the rear end of the ventilating duct of air heat exchanger is provided with flusher, both sides are provided with the differential pressure controller that is connected with control circuit before and after the ventilating duct of air heat exchanger, and the bottom of air heat exchanger is provided with the condensate drain pan of band drainage pipeline.
The utility model is work like this: under air heat exchanger ventilated normal situation, flusher did not carry out work.When the full dust of air heat exchanger knot or dust are tied when making differential pressure controller reach a certain setting value, differential pressure controller sends signal to control circuit, control circuit starts flusher, flusher sprays the current of high pressure with the reverse hydro-peening air heat exchanger of the opposite side of air-flow direction, thereby reaches the purpose of removing dust on air heat exchanger surface and the air heat exchanger slit.Sewage after the removing is discharged from after flowing into condensate drain pan.
Owing to adopted technique scheme, the utlity model has simple in structure, make and advantage such as easy to use easily, it is the scavenging air heat exchanger automatically, can not only guarantee the normal operation of air-treatment unit, also save great amount of manpower and material resources, realized the effect of economical and energy saving.
(4), description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. air heat exchanger; 2. differential pressure controller; 3. condensate drain pan; 4. shower nozzle; 5. water pipe; 6. water pump.
(5), the specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, the utility model includes air heat exchanger 1 and control circuit, it is characterized in that: the rear end of the ventilating duct of air heat exchanger 1 is provided with flusher, both sides are provided with the differential pressure controller 2 that is connected with control circuit before and after the ventilating duct of air heat exchanger 1, and the bottom of air heat exchanger 1 is provided with the condensate drain pan 3 of band drainage pipeline.
The utility model is work like this: under air heat exchanger 1 ventilated normal situation, flusher did not carry out work.When the full dust of air heat exchanger 1 knot or dust are tied when making differential pressure controller 2 reach a certain setting value, differential pressure controller 2 sends signal to control circuit, control circuit starts flusher, flusher sprays the current of high pressure with the reverse hydro-peening air heat exchanger of the opposite side of air-flow direction, thereby reaches the purpose of removing dust on air heat exchanger 1 surface and air heat exchanger 1 slit.Sewage after the removing is discharged from after flowing into condensate drain pan 3.
As shown in Figure 1, 2, flusher is the water pipe 5 that has shower nozzle 4, follows the water pump 6 of control circuit to be connected with water pipe 5.Control circuit controls the unlatching of water pump 6 or cuts out, and under the normal situation of ventilating, water pump 6 is in closed condition.In case when differential pressure controller 2 reached setting value, control circuit control water pump 6 was in opening, under the effect of water pump 6, water sprays to air heat exchanger 1 through water pipe 5, shower nozzle 4.
Claims (2)
1. self-cleaning air heat exchanger, include air heat exchanger (1) and control circuit, it is characterized in that: the rear end of the ventilating duct of air heat exchanger (1) is provided with flusher, both sides are provided with the differential pressure controller (2) that is connected with control circuit before and after the ventilating duct of air heat exchanger (1), and the bottom of air heat exchanger (1) is provided with the condensate drain pan (3) of band drainage pipeline.
2. self-cleaning air heat exchanger as claimed in claim 1 is characterized in that: flusher is the water pipe (5) that has shower nozzle (4), follows the water pump (6) of control circuit to be connected with water pipe (5).
