The shower room is equipped with: a drain pipe connected to the drain outlet; and a purging device for purging the chemical protective suit after rinsing to dry it. The purging device includes: an air inlet located on the side wall of the shower room and connected to the air inlet chamber, which provides purging gas to the shower room; an air outlet located on the side wall of the shower room and connected to the air outlet chamber, which extracts air from the shower room; and an entrance / exit door located on the side wall of the shower room, which fits tightly against the shower room during cleaning.

[0035] The solution disclosed in this utility model includes a spraying device and a purging device. The spraying device is used to rinse the chemical protective suits worn by personnel who have not yet removed them after handling a chemical spill. The purging device is used to purge the rinsed chemical protective suits to dry them. Compared with the solution where other personnel need to wear lower-grade chemical protective suits to clean the exterior of the chemical protective suits worn by the personnel handling the spill, this reduces the probability of the personnel handling the spill coming into contact with chemicals, thereby reducing the probability of secondary injury to the personnel handling the spill. Moreover, it also helps to reduce the probability of chemical residues on the surface of the chemical protective suits, and helps to reduce the workload of the personnel handling the spill and reduce the consumption of consumables (such as lower-grade protective suits, acid-absorbing cotton, etc.) during the handling of chemical spill accidents.

[0036] To make the above-mentioned objectives, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Figure 1 This is a structural schematic diagram of an embodiment of the shower equipment of this utility model.

[0038] refer to Figure 1 In this embodiment, the shower equipment is used to clean the chemical protective suits worn by personnel after handling a chemical spill accident. It includes: a chamber 100, comprising a shower chamber 101 and an air chamber 102 located on the side of the shower chamber 101. The air chamber 102 includes an air inlet chamber 103 and an air outlet chamber 104, with an isolation structure 105 between the air outlet chamber 104 and the air inlet chamber 103; and a spray device 110 for rinsing the chemical protective suit. The spray device 110 includes: a top water inlet 111 located on the top wall of the shower chamber 101; an inlet pipe 113 connected to the top water inlet 111; a drain outlet 114 located at the bottom of the shower chamber 101; and a drain pipe 115. The shower room 101 is connected to the drain outlet 114; a purging device 120 is used to purge the chemical protective suit after rinsing to dry it; the purging device 120 includes: an air inlet 121, located on the side wall of the shower room 101 and connected to the air inlet chamber 103, the air inlet 121 is used to provide purging gas to the shower room 101; an exhaust outlet 122, located on the side wall of the shower room 101 and connected to the exhaust chamber 104, the exhaust outlet 122 is used to extract air from the shower room 101; and an entrance / exit 130, located on the side wall of the shower room 101, which is tightly fitted to the shower room 101 during cleaning.

[0039] The red arrows indicate the direction of gas flow within the chamber.

[0040] The rinsing equipment includes a spray device 110 and a purging device 120. The spray device 110 is used to rinse the chemical protective suits that the personnel handling the chemical spill have not yet removed after the accident. The purging device 120 is used to purge the rinsed chemical protective suits to dry them. Compared with the solution where other personnel assisting in the handling need to wear lower-grade chemical protective suits to clean the exterior of the chemical protective suits worn by the personnel handling the accident, this reduces the probability of the personnel assisting in the handling of the accident coming into contact with chemicals, thereby reducing the probability of secondary injury to the personnel assisting in the handling of the accident. Moreover, it also helps to reduce the probability of chemical residues on the surface of the chemical protective suits, and helps to reduce the workload of the personnel assisting in the handling of chemical spill accidents and reduce the consumption of consumables (such as lower-grade protective suits, acid-absorbing cotton, etc.).

[0041] The chamber 100 is used to provide space for setting up the shower chamber 101 and the air chamber 102.

[0042] As an example, the chamber 100 is made of stainless steel, which has good strength and corrosion resistance. This reduces the probability of corrosion damage to the chamber 100 during cleaning, thus extending its service life. In other embodiments, the chamber may be made of other suitable materials.

[0043] The shower chamber 101 provides a process basis for setting up the spray device 110, the air inlet 121 and the air outlet 122.

[0044] In this embodiment, the shower room 101 is a visible shower room 101, which is beneficial for the assisting personnel outside the shower room 101 to understand and discover the situation inside the shower room 101 in a timely manner, so as to deal with any unexpected situations inside the shower room 101 in a timely manner.

[0045] In this embodiment, the shower chamber 101 includes a drainage zone I and an exhaust zone II. The drain outlet 114 is located in the drainage zone I, which helps to reduce the mutual influence between the drain outlet 114 and the exhaust outlet 122, thereby improving the effect of rinsing and purging.

[0046] The air chamber 102 is used to provide a process basis for setting up the purging device 120.

[0047] The air inlet chamber 103 is used to communicate with the air inlet 121, and the air outlet chamber 104 is used to communicate with the air outlet 122.

[0048] The exhaust chamber 104 and the air inlet chamber 103 are separated by an isolation structure 105, that is, the exhaust chamber 104 and the air inlet chamber 103 are mutually isolated.

[0049] In this embodiment, the air chamber 102 is located on the two opposite side walls of the shower chamber 101, and the air chambers 102 on the same side are isolated into an air inlet chamber 103 and an air outlet chamber 104.

[0050] The air chamber 102 is located on the two opposite side walls of the shower chamber 101, which helps to reduce the difficulty of connecting the air inlet chamber 103 with the air inlet 121 and the air outlet 104 with the air outlet 122.

[0051] In this embodiment, the isolation structure 105 between the exhaust chamber 104 and the air inlet chamber 103 is a baffle located in the air chamber 102. In other embodiments, the shower chamber can also serve as an isolation structure when the exhaust chamber and the air inlet chamber are located on different side walls of the shower chamber.

[0052] The spray device 110 is used to rinse the chemical protective suit to remove chemicals that have splashed or dripped onto it.

[0053] The top water inlet 111 supplies rinsing water into the shower chamber 101 from the top of the shower chamber 101.

[0054] In other embodiments, the top water inlet is located near the top of the shower chamber.

[0055] In this embodiment, the spray device 110 further includes: a bottom water inlet 112, which is disposed at the bottom of the shower chamber 101; the water inlet pipe 113 is also connected to the bottom water inlet 112; and the drain outlet 114 is disposed on the side of the bottom water inlet 112.

[0056] The bottom water inlet 112 is used to rinse the bottom (i.e., the sole) of the chemical protective suit, reducing the probability of chemical residue on the sole, thereby improving the rinsing effect of the protective suit.

[0057] Specifically, the drain outlet 114 is arranged around the bottom water inlet 112, which makes it easier for the bottom water inlet 112 to be close to the central area of ​​the bottom of the shower chamber 101, thereby reducing the difficulty of rinsing the bottom of the chemical protective suit.

[0058] The water inlet pipe 113 is used to connect the top water inlet 111 to an external water source, and to connect the bottom water inlet 112 to an external water source.

[0059] The drain outlet 114 and drain pipe 115 are used to discharge the wastewater after rinsing into the wastewater pool in the external environment.

[0060] In this embodiment, the spraying device 110 further includes a water tank 116, located at the bottom of the drain outlet 114, and connected to the drain outlet 114 and the drain pipe 115.

[0061] The water tank 116 is used to buffer the wastewater after rinsing, which helps to reduce the probability of water accumulating at the bottom of the shower chamber 101, and thus helps to reduce the probability of the chemical protective suit being secondary contaminated.

[0062] The purging device 120 provides purging gas to the shower chamber 101 through the air inlet chamber 103 and the air inlet 121, and extracts air from the shower chamber 101 through the exhaust chamber 104 and the exhaust outlet 122, so that the gas in the shower chamber 101 circulates, thereby realizing the purging treatment of the chemical protective suit after rinsing.

[0063] In this embodiment, when the air chambers 102 are located on the opposite side walls of the shower chamber 101, and the air chambers 102 on the same side are all isolated into an air inlet chamber 103 and an air outlet chamber 104, the side walls of the shower chamber 101 with the air chambers 102 are provided with air inlets 121 and air outlets 122, which helps to improve the uniformity of the purging process, thereby making the drying effect of the chemical protective suit better.

[0064] In this embodiment, the air inlet 121 is located on the side wall near the top of the shower chamber 101, and the air outlet 122 is located on the side wall near the bottom of the shower chamber 101. This makes it easier for the gas to circulate within the shower chamber 101, thereby improving the purging effect.

[0065] Specifically, there are multiple air inlets 121 and multiple air outlets 122, and the total area of ​​the air inlets 121 is the same as the total area of ​​the air outlets 122.

[0066] The presence of multiple air inlets 121 and exhaust outlets 122 further enhances the purging effect. Furthermore, the total area of ​​the air inlets 121 is the same as the total area of ​​the exhaust outlets 122, resulting in a better balance between the purging gas and the extraction gas, which also contributes to further improving the purging effect.

[0067] As an example, the air inlets 121 are arranged in a matrix, for example, in a 5*4 matrix arrangement.

[0068] It should be noted that the longitudinal distance between the exhaust vent 122 and the drain vent 114 should not be too small. If the longitudinal distance between the exhaust vent 122 and the drain vent 114 is too small, that is, if the exhaust vent 122 is located near the bottom of the shower chamber 101, the probability of wastewater splashing into the exhaust vent 122 after rinsing is increased. Therefore, in this embodiment, the longitudinal distance between the exhaust vent 122 and the drain vent 114 is greater than or equal to 100 mm.

[0069] In this embodiment, the inner height of the exhaust vent 122 is greater than its outer height, which helps to reduce the probability of wastewater after rinsing flowing into the exhaust vent 122.

[0070] The inner side of the exhaust vent 122 refers to the side closer to the shower room 101, and the outer side of the exhaust vent 122 refers to the side closer to the external environment.

[0071] In this embodiment, the purging device 120 further includes: an air inlet fan 123 located at the top of the shower chamber 101, with its air inlet 1231 located on the top wall of the chamber 100, and the air inlet 1231 communicating with the air inlet 121 through the air inlet chamber 103; and an exhaust fan 124 located at the bottom of the exhaust zone II of the shower chamber 101, with its air inlet 1241 located on the side wall of the chamber near the bottom of the chamber 100, and the air inlet 1241 communicating with the exhaust outlet 122 through the exhaust chamber 104.

[0072] The air intake fan 123 provides purging gas to the shower chamber 101 through the air intake chamber 103 and the air inlet 121, and the exhaust fan 124 extracts air from the shower chamber 101 through the exhaust chamber 104 and the exhaust outlet 122. Furthermore, the air intake fan 123 is located at the top of the shower chamber 101, and its air outlet 1231 is located on the top wall of the chamber 100. The exhaust fan 124 is located at the bottom of the exhaust zone II of the shower chamber 101, and its air outlet 1241 is located on the side wall of the chamber near the bottom of the chamber 100, facilitating gas circulation within the shower chamber 101.

[0073] Specifically, the power of the air intake fan 123 is the same as that of the exhaust fan 124, which facilitates the circulation of gas in the shower chamber 101 and also helps to reduce the pressure difference between the shower chamber 101 and the external environment, thereby improving the safety of the shower chamber.

[0074] In this embodiment, the flow direction of gas in the shower chamber 101 and the air chamber 102 is as follows: Figure 1 As indicated by the red arrow in the middle.

[0075] During cleaning, the entrance / exit 130 is tightly fitted to the shower chamber 101, which helps to reduce the impact of the cleaning process on the external environment of the chamber 100 and reduces the probability of the external environment of the chamber 100 being contaminated by chemicals.

[0076] It is understood that during cleaning, the entrance / exit 130 and the shower chamber 101 are tightly fitted together, that is, during cleaning, the entrance / exit 130 and the shower chamber 101 are sealed.

[0077] It should be noted that multiple cleaning processes can be performed to ensure the chemical protective suit is clean.

[0078] It should also be noted that the cleaning process usually takes less than or equal to 5 minutes to prevent the risk of suffocation to people in the shower room 101 due to excessive cleaning time.

[0079] In this embodiment, the entrance / exit 130 is located in the side wall of the shower chamber 101, which is not equipped with a water inlet 111, an air inlet 121, or an exhaust outlet 122. This helps to reduce the difficulty of setting up the entrance / exit 130 and also helps to improve the sealing performance of the entrance / exit 130.

[0080] Specifically, the entrance / exit 130 is equipped with a magnetic lock (not shown). When cleaning is performed, the magnetic lock is energized to seal the entrance / exit 130 with the shower chamber 101. When cleaning is completed, the magnetic lock is de-energized to allow the entrance / exit 130 to be opened. This helps to ensure that wastewater in the shower chamber 101 does not easily flow into the external environment during cleaning, thereby reducing the probability of external environmental pollution.

[0081] It should be noted that the entrance / exit door 130 includes an entrance door 131 and an exit door 132 arranged opposite to each other, so that personnel can enter the shower room 101 through the entrance door 131 and leave the shower room 101 through the exit door 132. This helps to reduce the probability of chemicals dripping near the entrance door 131 causing secondary contamination of the chemical protective clothing after cleaning.

[0082] It should also be noted that both the inlet door 131 and the outlet door 132 open outwards from the shower room 101 in one direction. This helps to further reduce the probability of the chemical protective suit being contaminated again after cleaning. It also helps to reduce the difficulty of entering the shower room 101 and opening the inlet / outlet door 130 from inside the shower room 101.

[0083] As an example, the shower room 101 is a visible shower room 101. Therefore, a viewing glass is provided on the entrance door 130 to facilitate making the shower room 101 a visible shower room 101.

[0084] In this embodiment, the shower device further includes a timer 140 located on the outer wall of the chamber 100. The timer 140 is used to display the remaining time of the cleaning process to remind the assisting personnel outside the shower chamber 101 to prevent the cleaning process from taking too long and causing the personnel inside the shower chamber 101 to be at risk of suffocation.

[0085] In this embodiment, the rinsing device further includes a pH meter 141, which is installed in the drain pipe 115 to obtain the pH value of the wastewater after rinsing and to infer the pH value of the leaked chemicals, thereby facilitating the assessment of the leakage accident level.

[0086] In this embodiment, the showering equipment further includes a control device 150, which is coupled to the spraying device 110 and the purging device 120. The control device 150 is used to control the process parameters of the spraying device 110 and the purging device 120. The control device 150 includes a control panel 151, which is located on the side wall of the chamber 100 facing the external environment.

[0087] The control device 150 is used to enable the shower equipment to perform automatic cleaning according to a preset setting, thereby reducing the need for personnel to operate the shower equipment and improving the automation level of the shower equipment.

[0088] Adjusting the process parameters of the spraying device 110 and the purging device 120 controlled by the control device 150 via the control panel 151 improves the convenience of adjusting the process parameters of the spraying device 110 and the purging device 120.

[0089] Understandably, the flushing time, the flow rate of the purging gas during the purging process (i.e., the airflow during the purging process), the purging time, and the number of cleaning cycles can be adjusted via the control panel 151. Specifically, since the cleaning time is typically less than or equal to 5 minutes, the number of cleaning cycles can be adjusted by changing the time of each flushing and purging process.

[0090] It should be noted that, since the entrance / exit 130 is equipped with a magnetic lock, and the entrance / exit 130 includes an entrance door 131 and an exit door 132 that are arranged opposite to each other; therefore, the magnetic lock is coupled to the control device 150, which helps to reduce the probability that the entrance / exit 130 is accidentally opened during the cleaning process.

[0091] Specifically, the shower equipment also includes an emergency stop button coupled to the control device 150. The emergency stop button includes a first emergency stop button 145 located on the inner wall of the shower chamber 101 and a second emergency stop button 146 located on the outer wall of the chamber 100.

[0092] The emergency stop button is used to stop the cleaning process in case of an accident involving personnel in the shower room 101, or to quickly stop the shower equipment in case of a malfunction.

[0093] More specifically, the distance between either or both of the first emergency stop button 145 and the second emergency stop button 146 and the bottom of the chamber 100 is 1 meter to 1.2 meters, so as to facilitate the rapid pressing of the emergency stop button in an emergency.

[0094] In this embodiment, the shower device further includes a timer 140 located on the outer wall of the chamber 100. The timer 140 is used to display the remaining time of the cleaning process. Therefore, the timer 140 is coupled to the control device 150 and is used to stop the cleaning process when the remaining time of the cleaning process is less than or equal to zero, which helps to further reduce the probability of suffocation risk to personnel in the shower room 101.

[0095] Specifically, the entrance / exit door 130 is equipped with a magnetic lock. The entrance / exit door 130 includes an inlet door 131 and an outlet door 132 arranged opposite to each other. The magnetic locks of the inlet door 131 and the outlet door 132 are both coupled to the control device 150 so that the timer 140 starts timing when the inlet door 131 is opened and stops timing and resets when the outlet door 132 is opened. This helps to accurately determine the remaining time for cleaning, thereby improving the effect of further reducing the risk of suffocation for personnel in the shower room 101.

[0096] In this embodiment, the shower equipment further includes an alarm device 147 located on the top wall outside the chamber 100 and coupled to the control device 150. The alarm device 147 is used to issue an alarm during cleaning and transmit the cleaning signal to the Emergency Response Center (ERC).

[0097] An alarm is triggered during cleaning to allow personnel outside shower room 101 to be aware of the operation of the shower equipment. The cleaning signal is transmitted to the emergency response center so that personnel inside the emergency response center can be aware of the operation of the shower equipment in a timely manner, thereby enabling personnel outside shower room 101 or personnel inside the emergency response center to take necessary safety measures during the cleaning process.

[0098] Specifically, the alarm device 147 includes an alarm light 148 located on the top wall outside the chamber 100, and an alarm (not shown) connected in series with the alarm light 148. During cleaning, the alarm light 148 illuminates to signal the operation of the shower equipment, allowing personnel outside the shower room 101 to promptly understand and monitor the operation of the shower equipment.
